Before Grand Theft Auto became a legend: Under which working title did the development of the first GTA begin?
Erklärung: Before Grand Theft Auto became synonymous with open worlds, limitless freedom and digital chaos, the project carried a much more harmless name: Race'n'Chase. But already under this working title slumbered one of the greatest legends in game history.
Race'n'Chase was the original working title of the first Grand Theft Auto. The Scottish studio DMA Design began development in Dundee in 1995. A preserved design document of the 22. March 1995 describes the project as a fast-paced multiplayer racing game focusing on chases, clashes and novel graphics techniques. Planned was a freely navigable city where players could take over different vehicles and compete either as policemen or criminals. Road traffic, pedestrians, police vehicles, missions and various urban areas were already the foundation of what would later become Grand Theft Auto.
During development, the focus shifted more and more from the classic racing game to the criminal side of the original robber-and-gendarm concept. Free exploration, stealing other people's vehicles and escalating chases proved to be more appealing than a fixed race. Thus, Race'n'Chase gradually developed into a game in which not the racetrack but an entire city became a playing field.
After a difficult development, the game appeared in 1997 under the new name Grand Theft Auto for MS-DOS, Windows and PlayStation. Already the first part contained versions of Liberty City, Vice City and San Andreas. The inconspicuous working title Race'n'Chase thus gave rise to the basic framework of a series that was to change the open-world genre sustainably.
Wrong answer Lead Foot (Screamer) – Screamer or Bleifuss was an independent racing series of the 1990s and had no direct connection with the development of Grand Theft Auto.
Wrong answer Hot Pursuit – Hot Pursuit was primarily known as the subtitle of Need for Speed III from 1998 and appeared only after the first Grand Theft Auto.
Wrong answer OutRun – OutRun is Sega’s legendary 1986 arcade racing game. It was neither a GTA working title nor a direct precursor to the series.

How to wake up a computer?
Erklärung: A sleeping computer seems turned off – but deep in its network card, a tiny guard is waiting for the right signal. Only the interaction between Magic Packet and WoL brings the machine back from its digital dream.
WoL stands for Wake-on-LAN and allows you to start a switched off or sleeping computer over the network. The network card remains in a particularly power-saving standby state and monitors incoming data. If it recognizes a correctly constructed Magic Packet, it sends a wake-up signal to the mainboard. The packet initially contains six bytes with the value FF and then sixteen repetitions of the MAC address of the target device. This allows the network card to clearly recognize that exactly this computer is meant.
For this to work, the mainboard, network card and operating system must support Wake-on-LAN and must be configured accordingly. Often the function must also be activated in the BIOS or UEFI. In the local network, the packet can be transmitted directly, over the Internet, usually additional router and security settings are necessary. Technically, therefore, both answers belong together: WoL denotes the function, the Magic Packet is the signal that triggers it.

Which legendary graphics card is considered the Holy Grail of the 3dfx era and impressed with four VSA-100 chips and 8x full-scene anti-aliasing?
Erklärung: Four graphics chips, 128 megabytes of memory and an image quality that seemed almost like future technology in 2000 — the never-regularly released Voodoo5 6000 became the holy grail of a lost 3dfx world.
The Voodoo5 6000 was planned as the final flagship of the Voodoo 5 family. On their massive board, four VSA-100 chips worked in the scan line interleave network. Each chip had 32 megabytes of its own memory, making the card carry a total of 128 megabytes. Since important graphics data had to be stored for each chip, these 128 megabytes did not completely correspond to a shared memory pool.
Their biggest weapon was the Sparse Grid Supersampling Anti-Aliasing realized via the T-Buffer. 3dfx used an offset sampling pattern, more precisely called rotated grid supersampling. Each VSA-100 calculated two slightly shifted image scans. Four chips combined a total of eight samples into one image and enabled 8x full-scene anti-aliasing. Not only polygon edges, but also textures, transparencies and fine image details were smoothed.
However, the construction was complicated, expensive and energy-hungry. Prototypes suffered from power supply, signal quality and AGP compatibility issues. An external power supply was therefore part of the unusual setup. Before 3dfx could bring the card into series production, the company was in massive financial difficulties. At the end of 2000, significant assets were acquired by Nvidia and the Voodoo5 6000 remained an almost unattainable prototype.
More than two decades later, Russian hardware developer Anthony Zxclxiv began a spectacular reverse engineering project. Without destroying an original, he reconstructed the complex circuit and developed his own board with four original VSA-100 chips, 128 megabytes of memory and more modern power supply. Its called Napalm 6000 S.U.X. Well-known replicas use the original drivers and BIOS versions and even reproduce different peculiarities of the original. Anthony produced several variants and offered individual copies for sale in small numbers.
Something happened that seemed impossible in 2000 — the never-released Voodoo5 6000 came into the hands of some enthusiasts decades later. It is not a newly developed modern GPU, but a passionately reconstructed continuation of the hardware whose official history was abruptly aborted.
Three decades after the appearance of Voodoo Graphics, active communities such as VoodooAlert, VOGONS and other 3dfx forums still exist. Cards are repaired, drivers adapted, rare prototypes documented and new hardware projects developed. The company has disappeared, but its technology and the voodoo magic cannot be extinguished to this day.
Wrong answer GeForce2 Ultra — Nvidia’s top-of-the-range model at the time was extremely fast and regularly available, but had neither four VSA 100 chips nor the characteristic 8×FSAA process of the Voodoo5 6000.
Wrong answer ATi Rage Fury Maxx — This card combined two Rage-128-Pro chips via alternate frame rendering. It was unusual, but belonged to ATI and not to the Voodoo family.
Wrong answer S3 Savage 2000 — S3’s ambitious graphics chip was known for its problematic Hardware T&L implementation, but technically it had nothing to do with the four-fold VSA-100 network.

Which of these games became legendary flagship titles of the 3dfx era and appeared with official Glide support?
Erklärung: When brown software rendering suddenly gave way to filtered textures, colored light and liquid 3D graphics, the voodoo spell began. Tomb Raider, Need for Speed 2 SE and Unreal became icons of this glide revolution.
With Voodoo Graphics, 3dfx transformed the PC into a real 3D gaming machine in the mid-1990s. The company’s proprietary interface Glide was tightly tailored to the hardware and let developers use functions such as bilinear texture filtering, perspectively correct textures, transparency, fog and dynamic lighting effects at high speed.
Tomb Raider received a special 3dfx patch, showcasing Lara’s first adventure with filtered textures, higher resolution and much quieter image. Need for Speed 2 SE made the difference particularly visible: vehicles and tracks seemed smoother, clearer and much smoother in the Glide version than in software mode. Unreal eventually became the great Cathedral of Light of the Voodoo era. Coloured lighting, fog, reflections and vast landscapes impressively demonstrated what accelerated 3D graphics could do in 1998.
These games were not the only titles with Glide support, but they became their most famous ambassadors. Those who switched between software mode and 3dfx version did not see a small difference in quality, but apparently a new generation of computer graphics.
Wrong answer Age of Empires – Ensemble Studios’ strategy game relied on a two-dimensional sprite and tile representation. An official Glide version was not part of its technical concept.

Which legendary sound card extension transformed simple MIDI sound into lively game music using sampled instruments?
Erklärung: When MIDI music still fluctuated between beeping synthesis and orchestral size, a small additional board transformed the sound card into an instrument store: the Wavetable module brought real samples into the games rooms.
A Wavetable module was an extension board for compatible sound cards. Instead of artificially generating instruments solely through simple FM synthesis, the module used digitally stored recordings of real instruments. A MIDI command did not contain the finished music, but information about instrument, pitch, punch strength and duration. The module chose the appropriate sample from its ROM and shaped the audible sound from it.
Many sound cards had a standardized wave blaster connection. Famous expansions included Roland, Yamaha, Creative and Orchid. Especially general MIDI music in games could win dramatically: guitars sounded more like strings, strings got depth and drums lost the typical metallic FM character. However, the result depended heavily on the respective sample ROM and its instrument assignment – the same MIDI piece could have a completely different effect on two modules.
In the DOS era, a high-quality Wavetable module was therefore almost the acoustic counterpart to the 3dfx card for sound enthusiasts: not a new game, but a completely new experience of the same game.

Which digital pest proliferates independently and crawls from computer to computer without a host file?
Erklärung: He does not need an infected file and no clueless double click: A Computer worm independently searches for the next system, copies itself over networks and can turn a single computer into a global epidemic.
A Computer worm is malware that can duplicate itself independently and spread over network connections. Unlike a classic computer virus, it does not have to attach to an executable host file. Many worms automatically scan for accessible systems, use known security vulnerabilities or send copies via email and message services. Once a new device is infected, the same process starts again.
This independence makes worms particularly dangerous. Within a short period of time, they can generate enormous amounts of network traffic, overload systems, install backdoors or reload other malicious programs. Historical examples such as Morris, Blaster, Sasser and Conficker showed how quickly a single infection can become a worldwide event.
Wrong answer Trojans – A Trojan disguises itself as useful or harmless software. It can cause great damage, but by definition does not spread like a worm on its own.
Wrong answer Rootkit – A rootkit is primarily used to hide attackers or harmful processes deep within the system and to maintain privileged access as undetected as possible.
Wrong answer Keyloggers – A keylogger records keyboard input, such as passwords or messages. Its task is surveillance, not independent distribution between computers.

What was the world’s first website?
Erklärung: Before the web was made up of billions of pages, it all started with an unassuming address and a handful of links. In 1991, info.cern.ch opened the first window into an information world that would change the planet.
info.cern.ch was the address of the first web server and the first publicly accessible website. Tim Berners-Lee developed the basic building blocks of the World Wide Web at CERN: HTML for structuring documents, HTTP for transmission and URLs for unique addressing. The NeXT computer used for this even carried a hint that it should not be switched off because a server was running on it.
The first page was visually unspectacular. She explained what the World Wide Web is, how hypertext works, what software is needed, and how other operators were able to create their own servers and websites. This was its revolutionary power: it not only presented information, but at the same time explained the open system with which everyone could link further information.
The original website was created in 1990 within CERN, in 1991 the web was opened to users outside the research facility. info.cern.ch did not grow into a single online service, but a universal network of documents, links and servers.

The sudden end of 3dfx buried big visions: Which of these graphics cards never reached regular trading?
Erklärung: When 3dfx fell silent in December 2000, two massive machines remained trapped between prototype and legend: the Voodoo5 6000 and the Spectre 4000 never reached regular trade. They became the lost future of a graphic empire.
The Voodoo5 6000 with four VSA-100 chips, 128 megabytes of memory and up to 8x full-scene anti-aliasing should become the ultimate model of the Voodoo 5 range. Several prototype revisions were built, but issues with power supply, AGP signal quality, cost and series maturity delayed publication. When 3dfx collapsed economically, the monstrous flagship was still not regularly available.
Even further into the future, the Spectre 4000 was targeted. Behind this name was a planned graphics card based on the Rampage chip. Rampage was designed to remove 3dfx from the Voodoo architecture that has been extended over the years, bringing features such as modern 32-bit display, a new memory interface and hardware support for transformation and lighting. Individual Rampage prototypes were already running, but for a finished sales platform the end came too early.
The Voodoo5 4500 and Voodoo5 5500, however, still made it into the trade in 2000. Thus, the two correct answers mark the lost future of 3dfx: a last brute voodoo and the new architecture with which the company once again wanted to compete against GeForce and Radeon.
Wrong answer Voodoo5 4500 – The entry-level model with a VSA 100 chip was actually sold and was available as a PCI and AGP version.
Wrong answer Voodoo5 5500 – The dual-chip model also reached trade. It became the most powerful officially released Voodoo graphics card.

What powerful compiler tool brings GoldSrc maps to life by calculating their static lightmaps using radiosity?
Erklärung: When geometry was in the Hammer Editor, the invisible alchemy of light began. Only HLRAD.exe distributed light energy over walls and floors and burned the static lightmaps that gave GoldSrc worlds atmosphere.
HLRAD.exe is the radiosity compiler of the GoldSrc tool chain. After processing the geometry, he examines the light sources of a map and calculates how light hits surfaces and is passed on indirectly from there. This radiosity principle takes into account not only directly illuminated surfaces, but also a simplified exchange of light energy between the surfaces. The results are written as static lightmaps into the BSP file.
The method could take a lot of computing time depending on the size, resolution and complexity of a map. For this, the lighting did not have to be calculated completely in real time during the game. GoldSrc was already able to display rooms with soft brightness profiles, colored light and a convincing atmosphere on hardware at that time.
Wrong answer HLVIS.exe – HLVIS calculates which areas of a BSP map are visible from each other. This visibility data prevents the engine from constantly drawing the entire world.
Wrong answer HLBSP.exe – HLBSP generates the spatial BSP structure from the prepared geometry and organizes the map for further processing.
Wrong answer HLCSG.exe – HLCSG disassembles and combines the brush geometry of the map. It prepares the constructive geometry, but does not calculate the final lightmaps.

Which famous PC game became the symbol of those compatibility issues that convinced Microsoft of a powerful Windows gaming platform?
Erklärung: A children’s movie stumbled Windows and helped change Microsoft’s view of PC games. The Lion King 1994 became a symbol of how urgently Windows needed a real gaming platform.
Disney’s The Lion King 1994 appeared at a time when many PC games were still being developed directly for MS-DOS. Windows did not offer developers an equally fast and unified path to graphics, sound and input devices. On different computers, games therefore encountered different drivers, graphics settings and performance limits. Just a Christmas product sold millions of times made visible how problematic this situation was for normal family computers.
Microsoft was already working on WinG, an interface for faster graphics output on Windows. Shortly after, a more comprehensive collection of game APIs was created under the code name Manhattan Project: DirectX. DirectDraw, DirectSound, DirectInput and other components should give developers shared access to the hardware and turn Windows from an office interface into a serious gaming platform.
The Lion King was not the technical origin of DirectX alone, but rather the frequently told story is symbolic of the compatibility crisis that Microsoft had to solve. This is exactly why The Lion King 1994 fits as an answer: A massively sold game clearly showed that PC gaming under Windows needed reliable standards.

Which messenger released in 1996 brought with its legendary “Uh-oh”! “ Instant communication to a worldwide audience?”
Erklärung: A short “Uh-oh!” “ was enough and millions of users knew immediately that a new message had arrived.” Released in 1996, Messenger ICQ brought personal real-time communication to the open Internet and became the soundtrack of an entire online generation.
ICQ was developed by Israeli company Mirabilis and published in November 1996. His name sounded pronounced like “I seek you” and thus described exactly his task. Friends could find each other on the Internet, see their online status and exchange messages almost without delay.
Each user received a unique numerical identifier, the so-called UIN. Early members had coveted short numbers, while later accounts got longer and longer sequences of numbers. Contact lists, status messages, file transfers, group chats and the unmistakable message noise made ICQ a model for numerous later messengers.
Mirabilis distributed the program for free and exploded its user base. Already in 1998, AOL bought the young company for several hundred million dollars. Later, ICQ changed hands again and lost importance in the age of smartphones. In June 2024, the service was finally discontinued. The legendary "Uh-oh"! He fell silent after almost 28 years.
ICQ was not the first form of digital instant communication at all. Chat systems, Unix Talk and IRC already existed before. His historic triumph was to make an independent Internet messenger with a personal contact list accessible to a global mass audience.
Wrong answer YAHOO — Yahoo Pager appeared in 1998 and was later renamed Yahoo Messenger. The service linked instant messages to Yahoo’s web offerings and user accounts.
Wrong answer AOL — AOL Instant Messenger was published in 1997 and emerged from the existing buddy list communication of the online service AOL. The independent AIM started after ICQ.
Wrong answer MSN — Microsoft released MSN Messenger in 1999 as a competitor to ICQ and AIM. The service later evolved into Windows Live Messenger and was largely replaced by Skype in 2013.
Erklärung: A short “Uh-oh!” “ was enough and millions of users knew immediately that a new message had arrived.” Released in 1996, Messenger ICQ brought personal real-time communication to the open Internet and became the soundtrack of an entire online generation.
ICQ was developed by Israeli company Mirabilis and published in November 1996. His name sounded pronounced like “I seek you” and thus described exactly his task. Friends could find each other on the Internet, see their online status and exchange messages almost without delay.
Each user received a unique numerical identifier, the so-called UIN. Early members had coveted short numbers, while later accounts got longer and longer sequences of numbers. Contact lists, status messages, file transfers, group chats and the unmistakable message noise made ICQ a model for numerous later messengers.
Mirabilis distributed the program for free and exploded its user base. Already in 1998, AOL bought the young company for several hundred million dollars. Later, ICQ changed hands again and lost importance in the age of smartphones. In June 2024, the service was finally discontinued. The legendary "Uh-oh"! He fell silent after almost 28 years.
ICQ was not the first form of digital instant communication at all. Chat systems, Unix Talk and IRC already existed before. His historic triumph was to make an independent Internet messenger with a personal contact list accessible to a global mass audience.
Wrong answer YAHOO — Yahoo Pager appeared in 1998 and was later renamed Yahoo Messenger. The service linked instant messages to Yahoo’s web offerings and user accounts.
Wrong answer AOL — AOL Instant Messenger was published in 1997 and emerged from the existing buddy list communication of the online service AOL. The independent AIM started after ICQ.
Wrong answer MSN — Microsoft released MSN Messenger in 1999 as a competitor to ICQ and AIM. The service later evolved into Windows Live Messenger and was largely replaced by Skype in 2013.

Which tool secretly turned many a one-sided 5 1⁄4-inch floppy disk into a data carrier with double capacity?
Erklärung: A bold cut with a Hole punch could turn a single-use 5 1⁄4-inch disk into a mysterious flippy disk. The data carrier could be turned over by a second write protection notch and filled with new data on its back.
In many drives, a 5 1⁄4-inch disk was read and described from only one side. On the right side of their flexible sleeve was a small notch, which the drive used to detect whether write access was allowed. If the disk was turned over, however, this notch was on the wrong side and the write sensor blocked access.
With an ordinary Hole punch or a specially offered floppy hole, a second notch was punched out on the opposite edge. After that, the disk could be turned and its previously unused back side formatted like its own data carrier. Such media used on both sides were appropriately called flippy disks.
Especially with home computers like the Commodore 64 and the Apple II, this trick was popular. Diskettes were expensive and programs needed more and more space. An additional notch therefore promised almost twice the usable capacity without having to buy another disk.
The secret memory doubling was not completely risk-free. For officially one-sided media, the manufacturer did not guarantee the magnetic quality of the back. In addition, both sides were described when turning in opposite directions, as a result of which abrasion and dirt could be distributed unfavorably. Nevertheless, the Hole punch was one of the most valuable tools next to the computer for many computer fans.

What could you do with a pencil?
Erklärung: For a short time, an ordinary pencil actually belonged to the tool of a PC tuner. With its conductive graphite, certain AMD processors could be unlocked and then switched to a modified multiplier Overclocking.
The so-called Pencil Trick became famous around the year 2000 by AMD's Athlon Thunderbird and early Duron processors for the socket A. On the ceramic surface of the CPU were several tiny contact pairs with the designation L1. If these bridges were separated, the processor multiplier remained locked.
A soft pencil left a trace of electrically conductive graphite when painted over. If the separate L1 contacts were connected to it cleanly, the motherboard recognized the multiplier no longer than predetermined. On suitable boards, the user could then select a higher multiplier in the BIOS or via switches and thus increase the processor clock.
The pencil therefore did not immediately increase the speed. It only unlocked the ability to set the CPU to Overclocking. For stable operation, sufficient cooling, suitable voltages and a processor that could handle the higher cycle were still necessary.
The graphite compound was cheap, but not particularly durable. Resistance, moisture and abrasion could cause it to fail again later. Enthusiasts therefore also used silver conductive lacquer. In newer generations of Athlon, AMD made it difficult to engage with laser-milled depressions between contacts. This slowly ended the wild time when a stroke with the pencil could unlock additional computing power.

With which button you could up to approx. Pentium 1 change the processor speed so that games in particular run at their intended speed?
Erklärung: The mysterious Turbo button made older PCs not only fast, but intentionally slow if necessary. It emerged as a lifeline for programs and games, the sequence of which directly depended on the clock speed of the processor.
Many early PC programs had been written for the 4.77 MHz of the original IBM PC. Animations, music and game speed were partly controlled by simple waiting loops. On a much faster 286, 386 or 486 such programs suddenly ran much too fast and could become difficult to play or even unusable.
When the Turbo mode was switched on, the computer worked with its regular high performance. After switching off, the system was braked. Depending on the mainboard, this was done by a lower processor clock, additional waiting cycles or deactivating the CPU cache. The exact effect was therefore different from computer to computer.
The contradictory name was mainly marketing. A switch marked Slow could hardly have been sold on a new high-performance PC. So the full speed was declared turbo and the slower compatibility mode was declared normal. Fittingly, many housings displayed two different MHz values via a small LED display, although this display often only represented numbers fixed by bridges and did not measure the actual clock.
With better programmed games, more modern operating systems and increasingly complex processor architectures, the button lost its usefulness. It was still to be found on some early Pentium cases, but at the latest afterwards one of the most curious buttons in PC history almost completely disappeared.

Which inseparable control sign duo forms the classic Windows line break of car return and line feed?
Erklärung: The escape sequence CR LF stands for Carriage Return (CR, wagon return) and Line Feed (LF, line feed) and comes from the time of mechanical typewriters and teletypewriters. CR puts the writing head at the beginning of the line, LF moves it one line down.
This combination is still used in Windows as a standard for line breaks. This becomes visible, for example, when you open text files from Windows in Unix or Linux systems – where the additional CR characters often appear as annoying control characters (e.g. B. ^M. Even in many network protocols such as HTTP or SMTP, CR LF still plays a technical role in separating headers and content. If you press the Enter button in Microsoft Word, for example, these two commands – cart return and line feed – are executed in the background to create a complete line break.

Which game relied on an exotic voxel space engine in the early 1990s, while the game world increasingly swore on polygons?
Erklärung: While other games built their worlds out of angular polygons, in 1992 Comanche: Maximum Overkill made soft valleys and endless hills rise from an exotic voxel space landscape – a sight like a different future.
Comanche: Maximum Overkill by NovaLogic became famous through its proprietary voxel space engine. Instead of calculating the terrain as a classic network of triangles, the engine used an elevation map and a color map. For each card position there was a terrain height, from which the renderer drew vertical sections from the player’s point of view and created a surprisingly organic landscape.
Strictly speaking, this world was not a completely freely modelable three-dimensional voxel volume, but a 2.5D altitude field technique. Overhangs, caves or superimposed levels were not directly possible. For vast valleys and mountains, however, the process was ideal and impressively fast on 386 and 486 PCs at that time.
The Need for Speed, Quake and Half-Life, on the other hand, rely on polygon-based 3D geometry. Comanche: Maximum Overkill became the great showcase of an alternative rendering idea, whose landscapes seemed almost like a glimpse into the future in 1992.

Which Windows 95 version supported the FAT32 file system?
Erklärung: Only Windows 95b and the Windows 95c based on it were able to deal with FAT32. Thus, Windows 95 broke the narrow partition limit of FAT16 and was finally better prepared for the rapidly growing hard drives of the late 1990s.
The original sales version of Windows 95 and the later Windows 95a only supported FAT16. This file system could usually only manage a partition up to a size of 2 GB under Windows 95. Larger hard drives therefore had to be divided into several drives such as C, D and E.
FAT32 was released in 1996 with Windows 95 OEM Service Release 2, commonly referred to as Windows 95b. With wider entries in the file allocation table, the system was able to address significantly more clusters. Large data carriers could thus be used as a coherent partition and small files often wasted less space due to smaller clusters.
Windows 95c was based on OSR 2. 5 and took over the FAT32 support of its predecessor. It was not an entirely new generation of Windows, but the last OEM edition of Windows 95 with additional components and updates.
Both versions were mainly for PC manufacturers and were shipped along with new computers. Owners of a regular Windows 95 version could not simply purchase OSR2 as an ordinary load upgrade. So FAT32 remained for many users initially a function, which they received only with a new computer or later with Windows 98 officially.

Which processor is considered the first commercially available one-chip microprocessor?
Erklärung: The Intel 4004 is the first commercially available microprocessor on a single chip. When it was unveiled in 1971, the tiny 4-bit building block unified the central processing unit of a computer in a silicon chip, ushering in a new era.
Its creation did not begin with a personal computer, but with an order from the Japanese computer manufacturer Busicom. The company originally required several special chips for a new family of programmable desktop computers. Intel developed a universally programmable solution, the heart of which became the Intel 4004.
Federico Faggin led the technical implementation, working with Ted Hoff, Stanley Mazor and Busicom engineer Masatoshi Shima, among others. The chip contained around 2,300 transistors, processed data in 4-bit increments and could handle about 92. Perform 1,000 commands per second. From today’s perspective, these values seem tiny, but in 1971, for the first time, a commercially offered CPU fit completely on a single chip.
The rights to the draft were initially partly with Busicom. However, Intel recognized the much greater potential of a freely marketable, universal computing unit and traded back the marketing rights. This turned a calculator building block into a product that showed that the same hardware could perform completely different tasks through different programs.
Wrong answer TMS1000 — The TMS1000 developed by Texas Instruments combined CPU, RAM, ROM and input and output functions on one chip. It is considered an early commercial microcontroller and only came on the market after the 4004.
Wrong answer Intel 8008 — Launched in 1972, the Intel 8008 was an early 8-bit microprocessor. He expanded the possibilities of the 4004, but appeared about a year later.
Wrong answer Z80 — Zilog released the 8-bit processor Z80 in 1976. It was largely compatible with the Intel 8080 and was later used in countless home computers, gaming systems and embedded devices.

What are the roots of the Half-life 1 Engine Goldsource?
Erklärung: Under Black Mesa beats the technical heart of another classic. Half-Life’s GoldSrc engine emerged from id Software’s licensed Quake engine, but was rebuilt by Valve to create its own identity.
When Valve began developing Half-Life in 1996, the young studio needed a powerful foundation for a fully three-dimensional game world. The Quake engine offered a suitable basis with BSP worlds, dynamic lighting, network code and a fast 3D renderer. In addition, smaller components from Quake II development were incorporated.
Valve replaced or extended much of the original code. GoldSrc received, among other things, its own animation system with skeleton models, color lighting, transparent textures, decals, improved AI, extensive script sequences and support for different renderers. Particularly important was the ability to stage action directly within the game world without constantly tearing the player out of action through classic cutscenes.
The name GoldSrc became common only later. While Valve worked on the technology for Half-Life 2, the studio internally distinguished between the stable, released Goldsource branch and the new Source branch. These names eventually evolved into the official names GoldSrc and Source.
The lineage remained visible. Console commands, card construction and various technical structures continued to remind Quake. From the same root, however, completely new worlds emerged with Half-Life, Counter-Strike, Team Fortress Classic and Day of Defeat. GoldSrc thus impressively shows how a licensed engine could become the foundation of an entire gaming era through radical conversion.

What is the name of the graphics interface for Voodoo graphics cards introduced by 3Dfx?
Erklärung: Glide was the proprietary graphics interface developed by 3Dfx, specifically optimized for Voodoo graphics cards. It offered high performance and enabled impressive 3D graphics with optimized edge smoothing and texture filtering, but was only compatible with 3Dfx hardware.
Glide was not a complete 3D engine, but rather a compact interface for rasterization of triangles. The game engine calculated on the CPU among other things positions, perspective, lighting and visible geometry. She then transferred the finished triangles to Glide, which produced pixels textured from them via the Voodoo hardware.
The API mapped the capabilities of the 3Dfx chips almost directly. Functions for drawing triangles, managing textures, setting depth buffer, transparency, fog, gouraud shading and texture filtering could be called without an extensive manufacturer-independent intermediate layer. Even the data formats used were closely adapted to the internal workings of Voodoo hardware.
This made Glide comparatively easy to learn and generated little additional administrative effort. This was especially valuable under DOS, where a uniform 3D driver architecture did not yet exist. Games were able to address the Voodoo hardware directly and reliably, instead of having to consider numerous different graphics cards and their peculiarities individually.
The name is derived from GL and refers to the conceptual proximity to OpenGL. However, Glide deliberately limited itself to functions that the Voodoo chips could actually perform quickly. This uncompromising specialization made the interface enormously efficient, but at the same time tied a game to the hardware of a single manufacturer.
Wrong answer DirectX — DirectX is a collection of Microsoft interfaces for graphics, audio and input devices. The actual 3D component is called Direct3D and supports hardware from various manufacturers.
Wrong answer OpenGL — OpenGL is a vendor-independent graphics interface originally developed by Silicon Graphics. For some OpenGL games, 3Dfx provided reduced MiniGL drivers.
Wrong answer PowerSGL — PowerSGL was a proprietary interface for PowerVR graphics chips. It also took a hardware-related approach, but belonged to a competing architecture.

What was the name of the technique that became popular with the Voodoo2 in 1998, in which two graphics cards rendered alternating picture lines?
Erklärung: SLI (Scan-Line Interleave) was introduced by 3Dfx in 1998 to connect multiple Voodoo2 graphics cards and distribute the computing load. This allowed the performance to be almost doubled by alternately rendering lines on each card.
Nvidia later acquired and improved SLI for modern GPUs.
Today, however, SLI is considered obsolete because modern games and engines are hardly optimized for multi-GPU systems. The technical effort for clean frame splitting, synchronization and driver support is high, while the actual performance gain often falls short of expectations. A particularly disturbing problem was so-called micro jerks – short, irregular delays in image output. These are created when two GPUs do not deliver images exactly evenly: a frame is e.g. B. displayed very quickly, the next one takes a little longer, although a total of many images per second are rendered. The result: despite theoretically high FPS, the image does not feel fluid because the human eye reacts to uniform movements. Especially in fast games, microbackers clearly disturb the gaming experience. Since modern graphics cards now offer enough performance to render even sophisticated titles with only one GPU smoothly, Nvidia has largely discontinued the classic SLI principle and instead relies on professional technologies such as NVLink.

What mapping techniques create additional surface detail without changing the actual geometry of the 3D model?
Erklärung: A flat polygon surface can look like rugged stone, although its silhouette remains completely unchanged. Parallax mapping, Bump mapping and Normal mapping create this illusion without adding additional geometry to the model.
Bump mapping typically uses a grayscale altitude chart to influence the surface normals during lighting calculation. Light thus appears to react to small elevations and depressions, although the underlying surface remains geometrically flat. If you look at its outer edge, the deception becomes visible, because the silhouette does not change.
Normal mapping stores the alignment of the simulated surface normals directly in the RGB color channels of a texture. As a result, significantly finer and more targeted light reactions can be represented than with simple bump mapping. The process became particularly important in games because details of high-resolution models could be transferred to significantly more economical polygon models.
Parallax mapping goes one step further and shifts the texture coordinates read depending on the viewing direction and height information. When moving the camera, depressions and elevations appear to move offset against each other. This parallax effect conveys spatial depth without changing the actual corner points of the model.
All three processes primarily change the representation of a surface and not its real shape. Therefore, collisions, shadow outlines and external silhouettes remain flat without additional techniques. Their great strength lies in producing the impression of a much more complex world with little geometry.
Wrong answer Displacement mapping — Displacement Mapping actually shifts the positions of the surface using an elevation map. In conjunction with sufficiently dense geometry or tessellation, real elevations are created that can also change the silhouette of the model.

What was the very first game console?
Erklärung: In 1972, the age of video game consoles began with the Magnavox Odyssey. The inconspicuous white box brought electronic games into private living rooms for the first time, although neither processor, memory or programmable software worked inside it.
The technical basis was developed under the direction of the German-American inventor Ralph Baer at Sanders Associates. Together with Bill Harrison and Bill Rusch he developed several prototypes from 1966. The most famous of these was the Brown Box, the technique of which was later licensed to the television manufacturer Magnavox.
In September 1972, the Magnavox Odyssey appeared as the first commercially released home game console. Their circuits only produced simple white dots, lines and blocks. Color, scores and elaborate backgrounds did not exist electronically. Instead, transparent slides were glued to the television and points were partly counted with cards, dice or play money.
The included cards contained no programs. They only connected certain contacts within the console and thus configured the fixed circuits for different game variants. Many supposedly different games therefore used the same electronic movement sequences and only got their identity through screen slide, rules and accessories.
A demonstration of the Odyssey tennis game also later inspired the development of Atari Pong. Thus, the Magnavox Odyssey was not only at the beginning of the console history, but indirectly helped to create a worldwide entertainment industry from a technical experiment.
Wrong answer Atari 2600 — Atari’s console, released in 1977, made programmable game modules popular worldwide. However, the Fairchild Channel F used such ROM cartridges as early as 1976 and the Odyssey appeared five years before the Atari 2600.
Wrong answer Coleco Telstar — Released in 1976, Telstar was a successful hard-wired Pong console. Their game variants were based on a special general instrument chip and not on freely programmable software.
Wrong answer Interton Video 2000 — This rare German console appeared in 1975 and offered several fixed ball games. Their cards configured existing circuits, but did not make them the first home game console.
Erklärung: In 1972, the age of video game consoles began with the Magnavox Odyssey. The inconspicuous white box brought electronic games into private living rooms for the first time, although neither processor, memory or programmable software worked inside it.
The technical basis was developed under the direction of the German-American inventor Ralph Baer at Sanders Associates. Together with Bill Harrison and Bill Rusch he developed several prototypes from 1966. The most famous of these was the Brown Box, the technique of which was later licensed to the television manufacturer Magnavox.
In September 1972, the Magnavox Odyssey appeared as the first commercially released home game console. Their circuits only produced simple white dots, lines and blocks. Color, scores and elaborate backgrounds did not exist electronically. Instead, transparent slides were glued to the television and points were partly counted with cards, dice or play money.
The included cards contained no programs. They only connected certain contacts within the console and thus configured the fixed circuits for different game variants. Many supposedly different games therefore used the same electronic movement sequences and only got their identity through screen slide, rules and accessories.

Which animal is known to be a symbol of a Trojan?
Erklärung: An apparent gift once opened the gates of Troy and thousands of years later became a symbol of digital deception. Behind the term Trojan therefore stands the Horse, in the interior of which according to mythology Greek warriors hid.
After ten years of unsuccessful siege, the Greeks feigned their withdrawal and left behind a huge wooden Horse before Troy. The Trojans considered it a gift and brought it to their fortified city despite urgent warnings. During the night, the fighters hidden inside got out, opened the gates for the returned army and sealed Troy’s downfall.
A digital Trojan works on the same principle of camouflage. It masquerades as a useful program, harmless attachment or interesting game, but performs a hidden harmful function after launch. This can steal data, install more malware or give attackers access to the system.
Technically, a Trojan is not automatically a virus. A classic virus multiplies by infecting other files. A Trojan, on the other hand, does not have to spread itself, because its decisive weapon is the trust of the user. The wooden Horse thus became the perfect symbol for a danger that does not penetrate by force, but is admitted voluntarily.

For which platform Cinema 4D version 1 appeared. 0?
Erklärung: Before Cinema conquered 4D Hollywood images and motion graphics, his journey began on the Amiga. The first version under the current name appeared there in 1993 and made the home computer the birthplace of a later world-famous 3D software.
The story began with brothers Christian and Philip Losch. Her Raytracer won a programming competition from Amiga magazine Kickstart in 1990. This resulted in FastRay, which was published in 1991 for the Amiga. Early scenes were still described via text files before the editor FRED enabled graphical operation.
In 1993, FastRay finally developed into Cinema 4D 1. 0. The first three generations were reserved for the Amiga. Only when Commodore’s insolvency threatened the future of the platform did Maxon begin a comprehensive new development in C++, through which Cinema 4D 4. 0 also reached Windows and Macintosh.
A competition entry for a home computer grew into a professional 3D suite, which was later used in advertising, television and cinema productions. The Amiga was not just an early target platform, but the technical laboratory where the entire Cinema 4D success story began.

On what unusual geometric basis did Nvidia’s first GPU, while triangles already conquered the upcoming standard?
Erklärung: Nvidia’s first GPU did not yet follow the triangle path that would later dominate the entire 3D world. The NV1 relied on Quadratic surfaces — an elegant vision that pushed Microsoft’s upcoming standard aside.
The 1995 Nvidia NV1 was fundamentally different from later graphics processors. While in competing accelerators, triangles established themselves as universal basic primitives, the NV1 worked with square areas and Quadratic Texture Mapping. Curved shapes could thus be generated from comparatively few parameters and directly textured.
This approach fit well with the equally unusual 3D architecture of the Sega Saturn and facilitated certain game implementations. However, the NV1 became Microsoft's Direct3D, which consistently relied on triangles. Triangles are always planar, geometrically unique and can be assembled to form almost any surface. Developers, engines and tools therefore followed the new standard.
The NV1 remained a fascinating sideway of GPU history. Their technique showed that the later triumph of the triangles was by no means self-evident. Nvidia initially relied on a different idea of how virtual worlds should be built and had to fundamentally realign its architecture after the failure.
Wrong answer B-Splines — B-Splines are curves or surfaces composed of several polynomial sections. In each case, control points influence only limited areas, so that shapes can be processed flexibly and locally.
Wrong answer NURB — NURBS are weighted mathematical curves and surfaces. They can represent complex freeforms as well as exact circles and are particularly often used in CAD and industrial design programs.
Wrong answer Voxels — Voxels describe three-dimensional space through single volume elements and thus resemble spatial pixels. They are suitable for terrain, medical scans and volumetric materials.

Which bug/glitch gave GTA 1 (Grand Theft Auto) the breakthrough and thus today's success?
Erklärung: Just one mistake in the Police AI turned an almost failed racing game into pure chaos. Instead of stopping the player under control, the police rammed him with full force and unleashed the very anarchy from which GTA was to emerge.
The project was initially called Race ’n’ Chase and was intended to facilitate chases from the perspective of policemen and gangsters. However, development has been difficult. The driving behavior was not convincing, the fun was missing and temporarily was even in the room to completely stop the project.
Then the faulty Police AI began to track the player much more aggressively than intended. Police cars no longer drove calculated routes, but rammed the getaway vehicle, caused mass carambola situations and turned any persecution into an unpredictable spectacle. The developers noticed that this seemingly wrong behavior caused enthusiasm among test players.
The team made chance the game principle and shifted the focus more and more to the role of the criminal. A conventional police game became an open world, in which rule breaking, escalation and improvised chaos determined the rhythm. The bug was not solely responsible for the later world success, but it showed DMA Design where the true soul of the game lay and helped transform Race ’n’ Chase into Grand Theft Auto.

What was the name of the first commercially successful mobile game?
Erklärung: With a few black pixels, Snake turned the Nokia 6110 into a portable game console in 1997. The simple hunting game became a worldwide phenomenon and proved for the first time in a big way that people also wanted to play on a mobile phone.
The Nokia version was programmed by Taneli Armanto. The principle was already known from older computer and slot games. An ever-lengthening snake collects points, but must not collide with a wall or with its own body. The few buttons, the monochrome display and the low processing power of a mobile phone at that time did not become an obstacle, but the perfect stage.
However, Snake was not the first game ever to appear on a mobile phone. As early as 1994, the Hagenuk MT-2000 was delivered with a version of Tetris. The historical difference made Nokia's enormous range and the standard pre-installation. Millions of users received the game automatically with their phone and did not have to buy a module or install additional software.
Later Nokia models spread new variants around the world. Over the infrared connection, some versions could even be played by two players against each other. A tiny pastime became the first major mass moment in mobile gaming and a harbinger of the gaming industry that would generate billions in sales on smartphones decades later.

To what value should Lara Croft's breast circumference have been accidentally scaled according to a well-known developer anecdote?
Erklärung: A slipped mouse cursor is said to have turned a small adaptation into one of the most famous design accidents in game history. Lara Croft's chest was accidentally scaled to 150% according to legend and the result remained in play.
The anecdote goes back to Lara creator Toby Gard. While working on the first Tomb Raider, he should actually only slightly enlarge the breast circumference of the still rough 3D model. Due to a wrong movement with the mouse, however, the value landed at 150%. When his colleagues saw the oversubscribed result, they allegedly convinced him to keep it.
The story fit perfectly with the time of Tomb Raider’s creation. Lara’s character consisted of only a few hundred polygons, which is why anatomical details could hardly be finely modeled. Their striking silhouette was therefore created from large, angular shapes that had to be immediately recognizable even from a distance.
Whether the famous mouse slider happened exactly like this can hardly be independently checked today. What is certain, however, is that Lara was not only shaped by its technical limitations in 1996. Marketing, covers and magazines overstated their appearance, turning involuntary scaling into a myth that would accompany the character for decades.

What was the name of the scandal Mod (sex minigame) of GTA - San Andreas?
Erklärung: In the code of GTA: San Andreas slumbered a secret that Rockstar would rather have buried deep. The Hot coffee Mod opened the door to a deactivated sex minigame in 2005, sparking one of the biggest scandals in video game history.
After successful dates, some friends invite Carl Johnson to the house with the ambiguous question of a cup of coffee. In the normal game, the camera stays outside and leaves the rest of the imagination. The name Hot coffee picked up exactly this moment.
Dutch modder Patrick Wildenborg released a PC modification in June 2005 that made the existing mini-game accessible. However, he did not create the scenes himself. Animations, dialogues and essential program parts were still included in the delivered game files and only blocked for the regular gameplay. Later, comparable content could even be activated in the console versions via manipulated saves.
This turned a curious discovery into a political and economic conflagration. The American ESRB changed the age rating from Mature to Adults Only. Large traders took the game off the shelves, Rockstar and Take-Two had to release a cleaned-up version and were targeted by the US Trade Authority FTC because of the original hidden content.
The scandal made Hot coffee famous far beyond the gaming scene. He posed an exciting question – Does a deactivated content already belong to the product sold if it seems unreachable, but is completely hidden on the data carrier?

What additional values can be used for securely storing password hashes?
Erklärung: When storing passwords securely, Salt and Pepper provide two different layers of protection. The culinary names sound playful, but with a database theft they can decide on millions of compromised accounts.
Passwords should never be stored in plain text and usually not reversibly encrypted. Instead, a special password hash function processes the password into a check value. When logging in later, the calculation is repeated and the result is compared with the stored hash. The server does not have to keep the original password for this.
The Salt is a random and unique value for each password. It is included before or during the hash calculation and may be stored together with the finished hash in the database. Two users with the same password thus receive different hash values. Pre-calculated tables lose their usefulness and an attacker must edit each stolen account individually.
A Pepper, on the other hand, is secret and is usually used for many or all password hashes of a system. It must not be in the same database together with the hashes, but belongs, for example, in a Secret Vault or a Hardware Security Module. If an attacker only steals the password database, he still lacks this additional secret value.
However, the two ingredients do not solve every problem. A salt does not prevent targeted password attempts and a pepper becomes worthless once the secret has also been compromised. Therefore, a deliberately slow and memory-intensive password hash function such as Argon2id remains crucial. Alternatives such as scrypt, bcrypt or suitably configured PBKDF2 also increase the effort of each individual rate attempt.
The division of tasks is therefore clear: Salt is unique, publicly storable and destroys precalculated mass attacks. Pepper is shared, top secret and additionally protects against an isolated stolen database. Only together with a strong hash process and a reasonable cost factor does a robust security concept emerge from the kitchen joke.

With which BNC termination resistance (terminator) did a 10BASE2 network have to be completed at a LAN party?
Erklärung: At a classic LAN party, a tiny component could decide victory or complete network chaos. The 50-ohm terminator swallowed signal reflections and reliably kept the aged 10BASE2 coaxial network alive.
A 10BASE2 network (also thin Ethernet or BNC network) had to be completed at both ends with a 50 ohm terminator. This resistance prevented signal reflections that would otherwise disrupt the network and make data transmissions unreliable. If one of these terminators is missing, the electrical signals at the open end of the cable reflect – this leads to data collisions, packet losses and, in the worst case, a complete breakdown of the connection. Especially at LAN parties, a forgotten or loose-fitting terminator regularly caused frustration: The entire network then did not work, and all participants had to carry out troubleshooting until the one missing resistance was found and correctly connected.

Which Apple computer launched a graphical user interface and mouse on the commercial market in 1983?
Erklärung: In 1983, Apple opened a window into the future with the Lisa. Instead of cryptic command lines, users expected a graphic desk, overlapping windows, icons, menus and a mouse — familiar elements that at the time seemed almost like science fiction.
Apple was inspired by the development of groundbreaking work on the Xerox PARC. Computers such as the Xerox Alto had demonstrated many concepts of a graphical user interface as early as the 1970s and the Xerox Star was commercially available in 1981. The Lisa did not bring this operating philosophy as the first computer at all, but for the first time in a commercially available Apple computer.
Documents could be placed as icons on a virtual desk, windows could be moved with the mouse and commands could be selected via menus. Together with programs for word processing, spreadsheets, diagrams and project planning, this should create a complete workplace for companies.
Technically, the Lisa was ahead of its time. He used a Motorola 68000 processor, offered a megabyte of memory, and had an advanced operating system with memory protection and cooperative multitasking. However, many of these capabilities required enormous computing power and made the operation partly slow.
For him, especially the introductory price of 9. $995, the unreliable Twiggy disk drives and the low software selection. The cheaper Macintosh adopted many of his ideas in 1984 and reached a much larger audience. Thus, the Lisa failed as a product, but won as a blueprint for the modern Apple computer.
Officially, Apple interpreted the name temporarily as Local Integrated Software Architecture. In fact, Lisa was the name of Steve Jobs’ daughter. What initially seemed like a technical acronym thus bore a very personal origin in the heart.

What graphics standard did the first Larry game Leisure Suit Larry - In the Land of the Lounge Lizards use?
Erklärung: The original 1987 DOS version of Leisure Suit Larry is usually called the EGA version. She presented Larry’s desperate search for love in 320×200 pixels and 16 colors, not the maximum EGA resolution of 640×350 pixels.
Leisure Suit Larry in the Land of the Lounge Lizards used Sierra's Adventure Game Interpreter, short AGI. Backgrounds were not simply stored as complete pixel images, but were built from character commands. This saved precious storage space and enabled an entire game world on the very limited data carriers and computers of the time.
The characteristic EGA representation used 16 simultaneously visible colors at 320 × 200 pixels. Although EGA could basically represent 640 × 350 pixels, Larry did not use this high-resolution mode. The player moved Larry with a keyboard or joystick through Lost Wages and entered actions such as “open door” or “talk to girl” via a text parser.
The game was a graphic reinterpretation of Softporn Adventure from 1981. Sierra initially expected a failure because of the adult theme and published Larry almost without advertising. However, after a weak start, the game spread through word of mouth and became a surprising success, spawning one of the most famous adventure series.
In 1991, Sierra published a completely redesigned version. This remake used the SCI engine, offered 256-color VGA graphics, and replaced text input with a mouse-controlled toolbar. Original and remake tell the same basic story, but technically they belong to two distinctly different generations of graphics.
Wrong answer CGA — CGA is strictly speaking not completely wrong under the current question, because the original version actually supported a CGA mode with four colors. As a characteristic 16-color version, however, the game is assigned to the EGA generation.
Wrong answer VGA — The original 1987 graphics were not designed as 256-color VGA images. VGA is part of the newly developed 1991 remake, which also used a different engine and a graphical mouse control.
Wrong answer SVGA — SVGA stands for later resolutions and color depths beyond VGA. Neither the original AGI version from 1987 nor the 256-color VGA remake from 1991 used SVGA as their actual graphics standard.

Where did the name Guybrush the protagonist from the game Monkey Island come from?
Erklärung: The strange name Guybrush actually originated while working with Deluxe Paint. However, the famous file was never called “guy”. brush. This often repeated version is a pretty legend, but technically impossible.
At the beginning of the development of The Secret of Monkey Island, the young would-be pirate did not yet have a name. The team just called him “the guy.” Artist Steve Purcell drew first drafts of the character in Deluxe Paint, a then extremely popular graphics program for pixel graphics and computer games.
In Deluxe Paint, image areas could be cut out as so-called brushes, saved and reused like digital stamps. Purcell therefore combined the provisional designation "guy" with "brush". The graphics file that Ron Gilbert received from him was finally named `guybrush. lbm. The internal filename first became the nickname of the nameless hero and finally his official first name.
The frequently told variant `guy. "Brush" cannot be true, according to Ron Gilbert. All graphics of the game were created on PCs under MS-DOS, whose file system extensions were limited to three characters. Deluxe Paint used formats such as LBM or BBM and did not add an ending. brush' on. The word “brush” was part of the actual filename.
The surname Threepwood was also not created by careful figure planning. He was selected in an internal competition at Lucasfilm Games and goes to the Threepwood family from the stories of British humorist P. G. Wodehouse back. Thus, one of the most famous heroes in game history owes his full name to a graphics function, a provisional file name and a literary vote. The fact that Guybrush later has to constantly explain what a name it is makes coincidence complete.
Erklärung: The strange name Guybrush actually originated while working with Deluxe Paint. However, the famous file was never called “guy”. brush. This often repeated version is a pretty legend, but technically impossible.
At the beginning of the development of The Secret of Monkey Island, the young would-be pirate did not yet have a name. The team just called him “the guy.” Artist Steve Purcell drew first drafts of the character in Deluxe Paint, a then extremely popular graphics program for pixel graphics and computer games.
In Deluxe Paint, image areas could be cut out as so-called brushes, saved and reused like digital stamps. Purcell therefore combined the provisional designation "guy" with "brush". The graphics file that Ron Gilbert received from him was finally named `guybrush. lbm. The internal filename first became the nickname of the nameless hero and finally his official first name.
The frequently told variant `guy. "Brush" cannot be true, according to Ron Gilbert.

Deluxe Paint used formats such as LBM or BBM and did not add an ending. brush' on. The word “brush” was part of the actual filename.

Which graphics card was the first to commercially introduce Hardware T&L?
Erklärung: The GeForce 256 brought Hardware T&L to the mass market for PC gamers in 1999. NVIDIA thus shifted a crucial part of the 3D geometry from the CPU to the graphics chip and confidently named the result “GPU”.
In a 3D scene, models are initially available in their own coordinate systems. The transformation shifts, rotates and projects its corner points into the camera perspective. The illumination level then calculates the brightness of the individual vertices on the basis of light sources, surface normals and material values. Before the GeForce 256, this work had to be done predominantly by the CPU on ordinary game PCs.
The chip developed under the code name NV10 integrated transformation, lighting, clipping, triangle setup and rasterization in a single solution. NVIDIA therefore called it the world’s first GPU and defined this term specifically via the fully integrated graphics pipeline. The chip had about 23 million transistors and was initially launched with SDR memory in October 1999. A little later followed the faster DDR execution.
The designation as the first GPU was effective marketing and must not be confused with the first graphics processor at all. Arcade systems, professional workstations and specialized multi-chip solutions had previously performed geometric calculations in hardware. The historical achievement of the GeForce 256 has been to establish hardwired Hardware T&L as an integrated and commercially available feature on a mass PC graphics card.
Wrong answer Renditions V1000 — The Vérité V1000 was an unusually programmable 2D and 3D accelerator in 1996, but did not have an integrated T&L unit. A later project of V2200 and Fujitsu Pinolite Geometry Processor was planned, but never reached the market.
Wrong answer ATI 3D Rage Pro — ATI’s 1997 chip combined 2D, 3D and video acceleration, but still left transformation and lighting to the CPU. ATI introduced its own Hardware T&L engine only with the later Radeon generation.
Wrong answer Matrox Millenium G400 — Released in 1999, the G400 shone with DualHead support and Environment Mapped Bump Mapping. However, it was a Direct3D-6 accelerator without a hard-wired transform-and-lighting unit.

What do you call a legitimate but fake Wi-Fi access point?
Erklärung: A familiar Wi-Fi name can hide a digital trap. A Evil twin mimics a legitimate access point and entices devices to establish their connection over a network that is completely under the control of an attacker.
For such an Evil Twin attack, the attacker sets up his own WLAN access point and gives him the same network name as a trusted network. Especially public WLANs in hotels, airports or cafes are easy to imitate, because their names are known and they often have no individual access control.
If the fake access point sends the stronger signal or a device selects it automatically, all traffic initially runs over the foreign hardware. The attacker can observe connections, redirect to manipulated login pages or try to intercept access data via a replicated captive portal. In corporate networks, Evil Twins are also used to entice users to enter their WLAN login data.
An encrypted HTTPS connection protects the content of a correctly secured website even within a hostile WLAN. The Evil twin cannot simply cancel such encryption. It becomes dangerous if users ignore certificate warnings, use unencrypted services or enter their passwords on a deceptively genuinely replicated page.
The name describes the attack perfectly. The real and the fake access point look almost identical to the user, but one of them pursues a completely different goal. An automatic connection setup thus becomes a digital mask from the comfort feature to the gateway and from a familiar WLAN name.

Which game made hidden secrets as Easter Eggs world famous?
Erklärung: Adventure made the Easter Egg a legend. In a secret room of the Atari-2600 game, Warren Robinett hid his own name, rebelling against a company policy that treated developers like invisible gears.
Warren Robinett developed Adventure almost alone in 1978 and 1979. Atari released the game in March 1980, but did not name the programmer on the packaging or in the manual. The company wanted to prevent successful developers from becoming known, from being recruited by competitors or from making claims for recognition and profit sharing.
Robinett therefore hidden the message “Created by Warren Robinett” in the program. To reach them, the player had to find a tiny gray dot in the catacombs of the black castle. The object consisted of only one pixel and became invisible from most backgrounds. Together with other objects, it had to be brought to a certain wall below the golden castle. Only then did the path into the secret room open.
Robinett did not tell anyone about his digital hideout at Atari and left the company. It was later discovered by 15-year-old Adam Clayton, who explained to Atari in a letter exactly how the secret room was accessible. Subsequent removal would have required the production of new ROM chips. Software director Steve Wright instead convinced the company to keep the secret, calling such hidden surprises Easter Eggs.
Strictly speaking, however, Adventure was not the first video game with a hidden developer greeting. In the 1977 Atari arcade game Starship 1, Ron Milner had already installed a secret key combination, the Hi Ron! “indicated and granted additional life.” This secret was only rediscovered decades later. Adventure, however, remains the game that made Easter Eggs famous and from a secret signature created a tradition of gaming culture that is still alive today.

Which long-standing historical data carrier lives on immortal as a symbol for “storage” to this day?
Erklärung: The Floppy disk disappeared from modern computers, but its angular silhouette survived as an immortal symbol of “storage”. Billions of times clicked, a former data carrier became a digital hieroglyph.
The symbol known today usually shows a 31⁄2-inch disk with a solid plastic cover, labeling field and metal slider. Despite its stable exterior, there was still a thin, flexible magnetic disk inside. From this flexible disc comes the name “floppy disk”.
In the 1980s and 1990s, the Floppy disk was part of the daily use of computers. Documents were stored on it, programs installed and files transported between computers. The popular HD version held 1.44 megabytes, which was sufficient for numerous texts and smaller programs at that time, but today would not even be enough for an ordinary smartphone photo.
As graphical user interfaces replaced more and more commands with small images, the disk was an obvious representation for permanently backing up a file. It had a clear silhouette and connected the abstract action directly with an object that almost every computer user knew. The representation of a concrete storage medium gradually became the general sign of the process itself.
When CD burners, USB sticks, hard drives and finally cloud storage displaced the disk, the icon remained. A full exchange would have forced millions of users to relearn a familiar control convention without providing any real benefit. This detached the sign from its original meaning. Even people who never held a real Floppy disk in their hands immediately recognize it as a request to save. The hardware died, but her spirit lives on in almost every program.

Which language is not a programming language?
Erklärung: HTML is not a classic programming language, but the markup language of the World Wide Web. It describes the meaning and structure of content, but does not formulate freely programmable algorithms or control processes.
HTML stands for HyperText Markup Language. Elements such as headings, paragraphs, images, tables, and shortcuts tell the browser what role content plays within a document. The browser reads these markings, generates a tree structure from them and then displays the page on the screen.
The language originated in the early 1990s in the context of the World Wide Web developed by Tim Berners-Lee and was influenced by SGML. Its revolutionary element was not complex computational logic, but the hyperlink. One document could suddenly point directly to another document on a remote computer and a worldwide network emerged from individual pages.
The appearance of a modern website is mainly handled by CSS, while JavaScript handles calculations, conditions, loops and dynamic behavior. HTML has interactive elements such as forms or foldable areas, but does not offer any general possibility to program any algorithms. Therefore, it is classified as an award language and not as a programming language.
Wrong answer Fortran — Fortran is one of the oldest higher programming languages. It was developed in the 1950s under John Backus at IBM for mathematical and scientific calculations and is still used in specialized fields today.
Wrong answer C++ — C++ was first created in 1979 by Bjarne Stroustrup at Bell Labs under the name “C with Classes”. The language combines hardware-related control with object-oriented and generic programming.
Wrong answer Java — Java was developed in the 1990s under James Gosling at Sun Microsystems. Programs are usually translated into bytecode and executed by a Java virtual machine on different operating systems.

Which letter code characterizes the German version of the legendary IBM PC keyboard to this day?
Erklärung: On the German version of the legendary IBM PC keyboard, the upper row of letters began with QWERTZ. Six keys became the name of a layout that has its roots in mechanical typewriters and has shaped millions of computers to this day.
QWERTZ is the variant of the English QWERTY layout, especially in German-speaking countries. The most striking difference is the exchange of Y and Z. In German, the letter Z occurs much more frequently than in English, while Y is relatively rarely needed. In addition, the German occupancy has its own buttons for Umlaute and the Eszett.
The basic arrangement goes on typewriters of the 19th century. century back. The QWERTY system evolved from the practical requirements of early typewriters, their mechanics and the then customary typewriters. The oft-told claim that all letters were distributed exclusively to avoid jamming type levers greatly simplifies this development.
IBM shaped the modern form of the layout with its PC keyboards. Especially the Model M, produced from 1985 onwards, became famous for its robust design, its interchangeable key caps and the characteristic Buckling Spring mechanism. At the stop, a small spring buckles in a controlled manner and generates the unmistakable click and a clearly tangible switching signal.
The American Model M usually had 101 buttons, international variants mostly 102. On the German versions appeared the familiar QWERTZ layout. Also the arrangement of function keys, separate number block, control block and arrow keys became the model of countless modern PC keyboards by this IBM generation.
Mechanical type levers have long since disappeared, but their linguistic and historical traces are still under our fingers. Anyone writing on a German PC keyboard today uses a layout that combines typewriter development and IBM PC history.

Which image formats can store a real alpha channel with multiple transparency levels?
Erklärung: True transparency knows more than just visible or invisible. PNG and TIFF can store graduated alpha values for individual pixels, enabling soft edges, transparent shadows and clean fades.
An alpha channel stores, in addition to the actual color values, how opaque a pixel should be displayed. A fully transparent pixel remains invisible, a fully covering pixel shows its full color. The values in between generate partial transparency and enable flowing transitions to the background.
PNG supports its own alpha channel with 8 or 16 bits per pixel for grayscale and real color images. The color values are stored in principle independently of the alpha value and are not automatically premultiplied. This makes PNG particularly suitable for web graphics, user interfaces, logos, shadows and optional motifs.
TIFF is much more flexible and can store additional channels for transparency. Depending on the application and file structure, both non-premultiplied and premultiplied alpha data are possible. TIFF is therefore often used in image processing, prepress and professional production processes.
Wrong answer GIF — GIF can only represent binary transparency over a selected pallet entry. A pixel is either fully visible or fully transparent. Soft transitions and semi-transparent edges are not possible.
Wrong answer JPEG — The classic JPEG format has no alpha channel and only stores image colors. Transparent areas must be charged with a fixed background color before storage.

Which buttons became the gaming standard?
Erklärung: Four nondescript letters became the cockpit of PC gaming. With WASD today controls an entire generation through virtual worlds, but the standard was not created on the drawing board, but from the wild mouse-and-keyboard experiments of early Doom and Quake players.
Early PC games often used the arrow keys for movement. As long as players only walked straight and turned over the keyboard, this scheme worked sufficiently. However, with fast first person shooters and free mouse control, everything changed. The right hand was needed for precise aiming and the motion control had to migrate to the left side of the keyboard.
A key figure in this development was the American Quake professional Dennis “Thresh” Fong. He moved with WASD, aiming with the mouse and dominating the early competitive scene. In 1997 he won the legendary Red Annihilation tournament and received John Carmacks Ferrari 328 as a prize. His control became a model for countless players.
The position of WASD offered another advantage. Around the four movement keys were conveniently accessible keys for jumping, ducking, racing, reloading and weapon exchange. Shift, Ctrl, Space, Q, E, R and the number keys could be used without having to move the movement hand far.
Other arrangements such as ESDF move the hand one button to the right, providing additional buttons on the left. Some players prefer this scheme to this day. However, the decisive cultural advantage was WASD. At the latest with Quake II, Half-Life and the following 3D shooters, the personal configuration of a professional player became a fixed language of PC control.

What is known to be synonymous with program errors or software anomalies?
Erklärung: The answer Beetle is aimed at the English word “bug”, which in computer language denotes a program error. The famous moth at Harvard Mark II made this expression immortal, but it did not invent it.
On 9 September In September 1947, a team at Harvard University investigated a disturbance in the Mark II electromechanical computer. Between the contacts of the relay number 70 in Panel F, the technicians found a pinched moth. They stuck the animal in the operating log and noted that this was the first actual case in which a bug had been found.
The wording was a pun, because “bug” was used for technical defects long before this event. Already Thomas Edison wrote in 1878 of small errors and difficulties, which settled into inventions and were called bugs. The term “debugging” for troubleshooting also existed before computer programs were created.
The moth was not a software error. It affected an electromechanical relay, causing a physical malfunction of the machine. Nevertheless, the entry became the perfect legend for a new era in which errors increasingly no longer lurked between gears or contacts, but invisibly in commands and memory states.
Often the discovery is attributed solely to the computer pioneer Grace Hopper. She worked with the Harvard team at the time and preserved the story, but the logbook entry itself speaks of several technicians involved. The original leaf with the glued moth was preserved and is now in the collection of the Smithsonian. Strictly speaking, the most famous Beetle in computer history was therefore a moth and the first documented real bug was by no means the origin of the word.

What does the Screen of Death represent after a BSoD critical system failure?
Erklärung: The legendary Blue screen appears when Windows detects a critical error and can no longer work safely. What seems like a sudden blue death sentence for users is actually the controlled emergency stop of the operating system.
In the Windows NT family, this process is internally called a bug check or stop error. The kernel stops the entire system if an error in the privileged system area can no longer be reliably intercepted. Possible causes are faulty drivers, defective memory, unstable hardware, corrupted system data or a serious error in the operating system itself.
Standstill does not prevent any data loss and does not repair any hardware. Above all, it is intended to prevent an already damaged system state from continuing and thereby falsifying even more data. Stop code, error parameters and, if applicable, the name of a driver involved provide clues to the cause. In addition, Windows can generate a memory image that developers later examine with debugging tools.
The classic white text on a blue background comes from Windows NT by developer John Vert. The graphics hardware at the time offered only a limited selection of colors and Vert worked in a development environment with exactly this color combination. The blue background was therefore not a psychological warning color, but a pragmatic decision that happened to become an icon.
One of his most famous public appearances was the Blue screen in 1998 at a presentation of Windows 98. When Microsoft employee Chris Capossela connected a scanner in front of Bill Gates to demonstrate plug and play, the computer crashed in front of an audience. The hall cheered and Gates dryly remarked that this is probably the reason why Windows 98 is not yet shipped.
Since Windows 8, the technical text was replaced by a sad face and a simpler message, later a QR code was added. In current Windows 11 versions, Microsoft even adopts the decades-familiar blue background in favor of a black error screen. The name BSoD should still remain, because hardly any other system error became such a powerful symbol of computer culture.

Under which code name was Windows 95 developed?
Erklärung: Before Windows 95 got its final name, it was created by Microsoft under the powerful codename Chicago. The project was designed to merge DOS and Windows more closely and take the hard-to-access PC into a new graphical era.
Development of Chicago began in 1992 shortly after the release of Windows 3. 1. Microsoft needed a system that could run modern 32-bit applications, work on affordable PCs and still not leave behind the vast world of existing DOS and 16-bit Windows programs. The result was not a completely new architecture, but a complicated hybrid of old compatibility and new technology.
Individual components of the project also received their own codenames. Jaguar designated parts of the 16-bit DOS substructure, Cougar the 32-bit core in protected mode, Panther the Win32 subsystem and Stimpy the new user interface. In early Chicago versions, the later Start menu still consisted of several buttons before the single Start button was created, which became the entry gate of Windows for decades.
With the start of sales on 24. In August 1995, the internal animal names disappeared behind a product that reorganized everyday PC life. Taskbar, Start Menu, Windows Explorer, Long Filenames and Plug and Play moved the computer closer to ordinary users. However, under the modern surface, DOS technology continued to work and preserved the connection to an older software world.
Wrong answer Whistler — Whistler was the codename of Windows XP. The name came from the Canadian ski resort of Whistler in British Columbia, which was popular with Microsoft employees and became part of a series of geographically linked project names.
Wrong answer Interface Manager — Interface Manager was an early working name for the product, which later became Windows 1. 0 appeared. Microsoft chose the name Windows before the public announcement because it described the graphical screen windows more clearly.
Wrong answer Longhorn — Longhorn was the development name of Windows Vista. Referring to a bar between the Whistler and Blackcomb ski resorts, he reflected Microsoft’s plan at the time to release Longhorn as a stopover between two major Windows projects.

What do some computer mice need for them to work?
Erklärung: Under the heavy rubber cover of earlier computer mice, a Ball worked as a mechanical motion translator. Without them, these models could not detect direction or distance and the mouse cursor remained motionless on the screen.
When moving the mouse, the Ball rolled over the table and set two rectangular rollers in motion. One captured the horizontal direction, the other the vertical direction. Perforated discs connected to the rollers interrupted light barriers and generated electrical pulses from which the computer calculated the direction of movement and the speed of the mouse cursor.
The principle of the ball mouse dates back to the 1960s. The German AEG-Telefunken presented its RKS 100-86 roller ball control system in 1968. While Douglas Engelbart’s famous wooden prototype still worked with two wheels running directly over the table, the free-rolling ball allowed movements in all directions and later became the standard for decades.
Their vulnerability knew every PC owner at that time. Dust, hair and skin fat wrapped around the rollers until the mouse cursor just jerked or completely refused a direction. Then the holding ring had to be opened, the ball removed and the hard-rolled dirt scraped from the axles. Optical mice finally ended this cleaning ritual with image sensors and digital surface analysis.
Wrong answer Zip Drive — The Zip drive released by Iomega was a removable storage for initially 100 megabyte magnetic disks. It was used to transport and secure large files, but had no function for motion detection of a mouse.
Wrong answer SCSI controller — SCSI mainly connected hard drives, scanners, tape drives and other peripherals to the computer. Mice usually used serial ports, PS/2, USB or special older bus systems and did not require a SCSI controller.
Wrong answer Webcam — A webcam takes pictures for video transmissions. An optical mouse even has a tiny image sensor that scans the surface in rapid succession, but does not need an external camera.

Which of these maps is not originally one of the official classic Counter-Strike maps?
Erklärung: Deck16 does not belong in the tactical universe of Counter-Strike. The dark industrial arena was created for Unreal and later as Deck16 [to one of Unreal Tournament's most famous deathmatch maps].
The original DM-Deck16 map appeared in Unreal in 1998 and was designed by Elliot “Mysha” Cannon. Unlike the realistically designed locations of Counter-Strike, it was a pure arena for fast death match. Nested levels, ramps, elevators, narrow transitions and a pool full of toxic liquid made any movement a risk.
For Unreal Tournament, the layout has been revised as DM-Deck16. The map rewarded players who memorized their weapon positions, paths, and elevation differences. Rockets, anti-aircraft missiles and the mighty Redeemer regularly turned the narrow corridors into an inferno. Numerous later reinterpretations made Deck16 a recurring sanctuary of the Unreal series.
Officially, however, Deck16 never belonged to Counter-Strike. Community members repeatedly recreated famous multiplayer cards for other engines and games, allowing Deck16 to show up outside of Unreal. However, such unofficial implementations do not change their actual origin.
Wrong answer Militia — cs_militia already appeared during the Counter-Strike beta phase as an official hostage release card. The terrorists entrenched themselves with their hostages in a remote property that had to be stormed by the counter-terrorists.
Wrong answer 747 — cs_747 came with Counter-Strike Beta 6. Add 0. The hostages were in a hijacked passenger plane whose narrow fuselage of doors, seats and narrow corridors formed an unusually oppressive site.
Wrong answer Dust — de_dust was created by David Johnston with Counter-Strike Beta 4. 0 published. The map was part of the then new bomb disposal mode and laid the foundation for the even more famous Dust II.

Which pixel block large units does the JPEG compression algorithm break down an image into?
Erklärung: The JPEG compression algorithm breaks down an image into 8×8 pixel blocks to efficiently compress the image data. Each block is then broken down into frequency components using discrete cosine transformation (DCT), removing redundant data and shrinking the file.
These 8×8 blocks are crucial for the efficiency of compression.
The choice of this block size – 8×8 – is a compromise between computing effort, memory requirements and compression quality. Smaller blocks would have fewer visible artifacts at high compression, but would require more processing power. While larger blocks could compress more efficiently, they create stronger visible block artifacts. 8×8 is a technically sensible middle ground, which is particularly suitable for DCT, since efficient algorithms exist for precisely this size – also with regard to hardware resources at the time of JPEG development.

Which vehicle do you start with in GTA San Andreas?
Erklärung: No limousine, no sports car and not even a rusty escape car is waiting for CJ. The first self-controlled vehicle in GTA San Andreas is a simple Bicycle, with which the player rolls back into the lost home.
Carl Johnson returns to Los Santos after five years in Liberty City because his mother was murdered. Even before he reaches Grove Street, his taxi is taken by the corrupt C. R. A. S. H. Police officers Frank Tenpenny, Eddie Pulaski and Jimmy Hernandez stopped. They threaten CJ, take his money and throw him out of their police car in the middle of the territory of the enemy Ballas.
Only there does the player take control. In the alley is a BMX ready, with which CJ should start the journey to his parental home. The Bicycle is thus not the first vehicle in which it can be seen during the opening, but the first that the player himself controls. This difference is crucial to the answer.
The inconspicuous start is deliberately chosen. CJ comes home without weapons, influence or respect and doesn’t even own a car. The bike takes the player slowly enough through Los Santos to perceive Grove Street, the Ballas and the new game world. At the same time, it presents one of the great innovations of San Andreas, because for the first time in the GTA series, bicycles could be ridden freely through the open world.
The BMX is more than just a mobile prop. Cycling trains CJ’s condition and their own bicycle skill. With growing experience, it accelerates better, jumps higher and falls less often from the saddle. Shortly afterwards, the bicycle in “Sweet & Kendl” even becomes the getaway vehicle of an entire gang. The path from the lonely BMX in a Ballas aisle to fast cars, planes and fighter jets already tells the entire rise of CJ.

Rise and Shine, Mr __________! Rise and Shine!
Erklärung: "Rise and Shine, Mr." Freeman is the ominous wake-up call that Half-Life 2 begins with. After years of rigidity, the enigmatic G-Man Gordon puts back on the playing field, as if even the elapsed time were only a tool in his hand.
At the end of the first Half-Life, the G-Man Gordon Freeman faces an apparent choice. Gordon accepts the offered employment relationship and disappears into a mysterious stasis. While hardly time passes for him, the earth is subjugated by the alien Combine power. Only about two decades after the Black Mesa disaster, the G-Man decides that his silent physicist is needed again.
Half-Life 2 does not begin with an explanation, but with the face of the G-Man, which emerges from darkness and blurred memory images. He speaks as if he were putting each word together from a foreign language. Eventually, Gordon awakens on a train to City 17, not knowing how many years have passed or why his hour has just come.
The scene summarizes the entire relationship between the two figures. Gordon has the name Freeman, but he never seems to be really free. The G-Man moves him through time and space, drops him off at crucial points and removes him as soon as his task is fulfilled. Who the alleged clients of the G-Man are and what goals they pursue, remains deliberately in the shadows.
His distinctive voice comes from Mike Shapiro, who also speaks Barney Calhoun in the same series. Through unnatural pauses, stretched syllables and an almost human tone, he turned a short wake-up call into one of the most famous entries in game history. Even before the player receives a weapon or is allowed to take a step, the G-Man makes it clear that Gordon Freeman is already part of a plan that only he himself seems to know.

Which drive letters are still reserved for historically and partially compatible floppy drives?
Erklärung: Even before hard drives were taken for granted in the PC, A: and B: belonged to the two floppy drives. This early order survived their data carriers and explains why Windows usually starts at C: until today.
The drive letter principle dates back to early computer systems such as CP/M and was later adopted by PC DOS and MS-DOS. The first disk space received A:, a second drive became B:. When the IBM PC appeared in 1981, hard drives were not a matter of course. Programs and operating systems started from 51⁄4-inch floppy disks, whose first PC versions only saved 160 kilobytes per page.
Even a computer with only one physical floppy drive could work under DOS with A: and B:. Both letters then alternately referred to the same drive. When copying, the system repeatedly asked the user to switch source and destination disks. With numerous floppy disk changes, DOS simulated a second drive that was not physically available at all.
When hard drives entered PCs, the first two letters were already assigned. The first disk partition therefore received C:. From this simple order emerged one of the most long-lasting conventions in computer history. Programs, installation routines and later Windows itself expected the system drive at this point, which kept C: even after the floppy disappeared.
Under modern versions of Windows, A: and B: are no longer exclusively reserved for floppy drives. They can also be assigned to other volumes. However, older programs and certain system functions may still treat these letters as disk drives or react unusually to them. Therefore, the two seats often remain empty and remind like two invisible ghost drives of the time when a PC asked for the next disk to copy a file.

Which of these games did not appear on 51⁄4-inch floppy discs in its original DOS sales version?
Erklärung: As PC games got bigger and data hungrier, the reign of the bendable 5 1⁄4-inch disk slowly ended. Cannon Fodder reached the PC in 1994 already on three compact 31⁄2-inch floppy disks.
Cannon Fodder first appeared in 1993 for the Amiga, on which 31⁄2-inch disks had long been part of familiar everyday life. The DOS implementation followed in 1994 and was delivered in its regular sales version on three 31⁄2-inch HD disks with 1.44 megabytes each. The game then had to be installed on a hard drive and occupied about ten megabytes there.
The smaller disk looked harder and more modern, but technically remained a real floppy. A thin and flexible magnetic disc still rotated in its solid plastic sheath. A metal slider protected the sensitive surface, while the higher storage capacity allowed manufacturers to ship larger games with fewer disks.
The older response options come from a phase in which many PCs were still equipped with 5 1⁄4-inch drives. Their DOS editions were therefore also sold on these large black disks, partly in parallel with variants on 31⁄2-inch disks. Depending on capacity, a single game could fill an entire stack of data carriers and turn the installation into a small ceremony of insertion, waiting and floppy change.
Cannon Fodder thus stands exactly at a historical breaking edge. While his black humor and tiny soldiers still look completely like classic Amiga and DOS era, his data carrier was already a harbinger of the end of the big floppy. Shortly afterwards, growing data volumes and CD-ROM drives should finally displace the 31⁄2-inch disk from the game boxes.

Which data type does not allow floating point numbers?
Erklärung: Between positive and negative values, Integers knows only whole steps. The data type stores numbers such as −12, 0 or 2048, but no values with a fraction. For numbers like 3.14, on the other hand, floating point or other suitable number types are required.
A Integers represents an integer within a defined range of values. How large this range is depends on the bit width used and on whether the type has a sign. For example, an 8-bit signless integer can represent values from 0 to 255, while a 32-bit sign integer can usually represent values from −2. 147. 483. 648 to 2. 147. 483. 647 is enough.
Float, double and single are used for floating point numbers. In many systems, float or single corresponds to the 32-bit format IEEE 754, while double usually uses 64-bit. The larger bit width of Double allows more significant digits and a larger value range, but also requires more memory.
Floating point numbers store a value simplified as sign, exponent and mantissa. As a result, they can represent extremely large and very small numbers, but do not exactly represent many decimal values. Even a seemingly harmless calculation such as 0.1 plus 0.2 can therefore internally produce a slightly different result.
Integers calculations are accurate as long as their allowed value range is not exceeded. They are therefore suitable for counters, indices, unit numbers, memory addresses and many logical states. Float, double and single, on the other hand, are required if measured values, positions, physical quantities or other values are to be represented between two whole numbers.

In which programming language were approximately 75 percent of the published source code of Adobe Photoshop 1. 0. 1 written?
Erklärung: About three quarters of Photoshop 1’s published source code. 0. 1 consist of Pascal. Behind the later image editing legend was not a huge development team, but mostly the amazingly clear work of a single programmer.
Thomas Knoll started at the University of Michigan in 1987 with a small program called Display, which could display grayscale images on a Macintosh screen. His brother John worked at Industrial Light & Magic and realized the potential of the inconspicuous tool. Together, they expanded it to include selection tools, filters, color corrections and support for various file formats. Display first became ImagePro and finally Photoshop.
Adobe licensed the program in 1989 and released Photoshop 1. 0 Early 1990 exclusively for the Macintosh. Thomas Knoll wrote the actual application largely in Pascal alone, while John developed numerous image processing plug-ins. Where maximum speed was required, for example in particularly computer-intensive routines, assemblers tailored directly to the Motorola 68000 processor were used.
Version 1 source code published by the Computer History Museum in 2013 0. 1 contains 179 files and approximately 128. 000 mostly uncommented program lines. About 75 percent of these are Pascal, about 15 percent Motorola 68000 assemblers and the rest consists of different data. Apple's licensed MacApp library could not be co-published.
Despite its age, the code already contains structures that evolved in later Photoshop versions. These include image processing tiles, filters and processes for images that were larger than the available working or screen memory. There were no levels yet. This today fundamental tool only appeared in 1994 with Photoshop 3. 0. A manageable Pascal program of two brothers became a software whose name eventually even became the verb for changing images.

What does NVIDIA mean?
Erklärung: Envy is the right track, but NVIDIA is not an abbreviation or a direct connection from “invidia” and “videre”. The name originated from a provisional abbreviation and the Latin word “invidia”, which actually means envy.
When Jensen Huang, Chris Malachowsky and Curtis Priem founded their company in 1993, it did not initially have a definitive name. They therefore marked designs and files with “NV”, an abbreviation for “Next Version”. Curtis Priem had previously worked on graphics chips at Sun Microsystems and wanted to create their next generation.
When the company was to be officially registered, the founders searched for a name that contained the letters N and V. One of their ideas was “NVision”, but this designation was already given. Finally, they came across the Latin word “invidia”, which means Envy. This resulted in NVIDIA, a name for technology that competitors should look envious of.
However, the connection to seeing is not completely seized from the air. The Latin “invidia” goes back to “invidere” in linguistic history, which means an unfavorable sighting. The eye-shaped company logo also captures the world of vision and computer graphics. However, it does not immediately explain the origin of the name.
The irony of this self-confident choice was already evident with the first product. The NV1 published in 1995 relied on an unusual graphics architecture and failed almost devastatingly on the market. NVIDIA narrowly escaped the sinking, changed its technical course and landed the decisive hit with the RIVA 128. The company, which had named itself after the Envy, had to earn it only through one of the most spectacular catch-up hunts in chip history.
Erklärung: Envy is the right track, but NVIDIA is not an abbreviation or a direct connection from “invidia” and “videre”. The name originated from a provisional abbreviation and the Latin word “invidia”, which actually means envy.
When Jensen Huang, Chris Malachowsky and Curtis Priem founded their company in 1993, it did not initially have a definitive name. They therefore marked designs and files with “NV”, an abbreviation for “Next Version”. Curtis Priem had previously worked on graphics chips at Sun Microsystems and wanted to create their next generation.
When the company was to be officially registered, the founders searched for a name that contained the letters N and V. One of their ideas was “NVision”, but this designation was already given. Finally, they came across the Latin word “invidia”, which means Envy. This resulted in NVIDIA, a name for technology that competitors should look envious of.
However, the connection to seeing is not completely seized from the air. The Latin “invidia” goes back to “invidere” in linguistic history, which means an unfavorable sighting. The eye-shaped company logo also captures the world of vision and computer graphics. However, it does not immediately explain the origin of the name.
The irony of this self-confident choice was already evident with the first product. The NV1 published in 1995 relied on an unusual graphics architecture and failed almost devastatingly on the market. NVIDIA narrowly escaped the sinking, changed its technical course and landed the decisive hit with the RIVA 128. The company, which had named itself after the Envy, had to earn it only through one of the most spectacular catch-up hunts in chip history.

Where did the legendary landscape of the Windows XP wallpaper “Bliss” hide, which millions of people had in mind every day for years?
Erklärung: Billions of people looked at the same green hill for years and suspected Ireland, New Zealand or digital magic. But “Bliss”, probably the most famous wallpaper in the world, hid in a real place in California.
The Windows XP wallpaper "Bliss" was created in 1996 in the Los Carneros wine region in Sonoma County, California. Photographer Charles O’Rear drove through the region on a country road as he was fascinated by the intense green of the hill under the deep blue sky. He stopped and photographed the scene with a medium format camera on Fujichrome color diafilm.
The almost unreal colors were not the result of a completely computer-created landscape. The highly saturated slide film, the fresh grass after a rainy time and the clear weather gave the picture its characteristic look. Microsoft later acquired the rights and chose the photo as the default background for Windows XP. Due to the enormous spread of the operating system, the landscape of California became one of the most viewed motifs in the history of photography.
Today the hill looks very different. Vines grow again on the site, and the immaculate green area no longer exists in this form. This is precisely why “Bliss” seems like a frozen moment: a real landscape that became the gateway to the digital world for millions of people.

The game Blockbuster Grand Theft Auto was originally developed by DMA-Design. Which game made the studio known?
Erklärung: With Lemmings, DMA Design transformed tiny pixel beings into a worldwide phenomenon in 1991. Long before Grand Theft Auto plunged entire cities into chaos, the studio left millions of players desperately saving little green-haired creatures.
The idea came about almost by chance in Dundee. Mike Dailly experimented with Deluxe Paint for the unfinished game Walker and tried to reduce a believable figure to just 8×8 pixels. As his tiny males marched across the screen, programmer Russell Kay realized the potential hidden in it and is said to have exclaimed, There's a game in that! From this small animation grew one of the most original thinking games of his time.
Instead of directly controlling a single character, the player had to assign limited abilities to a seemingly unwilling mass. Some lemmings became climbers, others built stairs, dug tunnels or sacrificed themselves with an explosive bang. The player never fully mastered the Horde, but was only allowed to intervene in their unstoppable march at the right moment.
The Amiga game released by Psygnosis in 1991 was broadcast to more than twenty systems. It was precisely this mixture of cute presentation, black humor and mercilessly precise puzzles that made DMA Design internationally known. A few years later, the same Scottish studio created Grand Theft Auto and eventually became Rockstar North. The rights to Lemmings, on the other hand, remained with Psygnosis and came to Sony through its acquisition. So the paths of the two great legacies of the studio separated: the Lemmings marched to PlayStation, while DMA Design set off for Liberty City.

Which was the first web browser, which was also developed on a Steve Jobs NeXT computer?
Erklärung: The browser was first called WorldWideWeb when it was created and was later renamed Nexus. On a NeXT computer, Tim Berners-Lee not only created the first web browser, but also an editor for the young web.
Tim Berners-Lee developed the program at CERN in 1990 on a black NeXT workstation. The object-oriented development environment of the company founded by Steve Jobs allowed him to make his idea a reality surprisingly quickly. The program could not only display web pages, but also edit them and create new links. The browser and web editor were originally a single tool.
The browser initially bore the same name as the entire project: WorldWideWeb. To end this confusion, it was retroactively renamed Nexus in 1994. Together with the first web server and the first website on info. cern. He formed the gateway to an information space that would span the world a few years later.
Wrong answer NCSA Mosaic — Mosaic was developed in 1992 by Marc Andreessen and Eric Bina at NCSA and published in 1993. The browser made the web popular through its ease of use and images displayed directly in the text, but was not the first.
Wrong answer Netscape Navigator — The 1994 published browser was created by Netscape Communications around Marc Andreessen and Jim Clark. He built on the experience of the Mosaic team and conquered the early commercial web, but appeared years after Berners-Lee’s browser.
Wrong answer Viola — This refers to ViolaWWW, which Pei-Yuan Wei developed for Unix systems with the X Window System from 1991. It was an early graphical and programmable web browser, but was not created on a NeXT computer or before WorldWideWeb.

What about the Millennium Bug (Y2K problem)?
Erklärung: The millennium bug, also known as the Y2K problem, mainly affected older computer systems that only stored year numbers in two digits – i.e. B. “99” instead of “1999”. When the 1. January 2000 came along, many of these systems interpreted the “00” not as 2000, but as 1900.
This led to incorrect calculations, incorrect date comparisons and, in the worst case, system crashes or wrong behavior – e.g. B. in financial systems, time recordings, flight bookings or industrial installations.
The origin of this problem was in early computer technology: in the 1960s to 1980s, storage space was extremely expensive and scarce. To save resources, the date was often stored with only two digits. With millions of data sets – for example in banks or authorities – this meant considerable savings. In addition, many developers believed that their software would not run for more than a few years anyway – no one thought that programs from 1970 could still be active in 2000.
This seemingly harmless decision led to a global IT problem decades later. Fear of potential disasters led to major investments in testing, updates and emergency plans worldwide. Ultimately, there were no serious failures – not because the danger was low, but because it was defused in time by extensive preparations. The Millennium Bug is still considered one of the most expensive but also the most instructive lessons in the history of software development.

Who built the world's first functional binary floating-point computer in 1941?
Erklärung: In 1941, Konrad Zuse built the world’s first functional floating-point binary machine, the Z3. It was the first fully automated, programmable computer and worked with binary floating-point arithmetic.
Zuse’s work laid the foundation for modern computer technology.
The use of floating point numbers was a key advance, as they made it possible to efficiently represent both very large and very small numbers with a dynamic range of values. Unlike integers, which can only cover fixed value ranges, floating point numbers allow more mathematically precise calculations across multiple orders of magnitude. This is especially essential for scientific calculations, technology, simulations and graphical applications. The fact that Zuse already used floating-point arithmetic in the Z3 in the 1940s shows how visionary his work was – and why it is considered a milestone in the history of the computer.

In which computer game was the SCUMM system first used?
Erklärung: Maniac Mansion was not only a wonderfully weird adventure in 1987, but the birthplace of SCUMM. The system developed especially for the game became the invisible foundation of numerous later Lucasfilm and LucasArts classics.
Ron Gilbert wanted to create an adventure game whose characters, rooms and puzzles no longer had to be carved directly into the program code. Together with Aric Wilmunder, he developed his own scripting language and runtime system at Lucasfilm Games. Its name already completely revealed its original purpose: Script Creation Utility for Maniac Mansion.
SCUMM separated the actual game story largely from the technology of the respective platform. Rooms, objects, dialogues and character actions could be described as scripts and then transferred to different computers. At the same time, the selection of visible verbs such as "Open", "Use" or "Tamm" replaced the previously common text input parser. From a tool for a single game, a long-lasting adventure machine emerged, which later brought Zak McKracken, Indiana Jones, Loom and Monkey Island to life.
Wrong answer Leisure Suit Larry — The 1987 original used Sierra’s Adventure Game Interpreter, AGI for short. The graphically renewed remake from 1991, on the other hand, switched to Sierra's more powerful SCI system.
Wrong answer Zak McKracken — This adventure also ran with SCUMM. However, it did not appear as a second SCUMM game until 1988 and already used a further developed version of the system created for Maniac Mansion.
Wrong answer Out Run — Segas arcade racing game was not based on a comparable adventure system. It ran on special Sega-OutRun hardware, which was based on System 16 and with its super-scaler technology rapidly enlarged sprites as an apparent 3D world on the road.

Which operating system was advertised with the song [Rolling Stones - Start me Up]?
Erklärung: Windows 95 did not march quietly into the computer world. Microsoft had the Rolling Stones “Start Me Up” on and transformed the new Start button into the icon of an operating system that finally put the PC in the center of everyday life.
The title of the song fit perfectly with one of the most visible new features of Windows 95, the start menu. Microsoft not only wanted to sell software, but to stage the beginning of a new PC era. Worldwide market launch on the 24th. In August 1995, people stood outside the shops at night while the commercial with the striking guitar riff thundered across the screens.
The license itself was a piece of music history. Mick Jagger and Keith Richards had long resisted releasing their songs for advertising. The negotiations dragged on for months and Microsoft is said to have paid around three million US dollars. Initially, the company even received a newer recording, but insisted on the familiar 1981 studio version. This made “Start Me Up” the first Rolling Stones song the band released for an advertising campaign.
Microsoft pushed the staging even further. Jay Leno moderated the big presentation on the company premises, newspapers were covered with Windows advertising and even people without their own computer suddenly knew the start button. An operating element became an icon and a product launch a pop culture event, whose guitar riff is still inextricably linked to Windows 95 today.

How many characters could you send with a single SMS?
Erklärung: The famous 160 signs were not an arbitrary limit, but the result of a brilliant technical search for a place. Only 140 bytes became a communication format that shaped an entire generation.
A classic SMS does not transport its text via its own data channel, but uses free capacities in the signal channels of the GSM network. For the actual message, only 140 bytes or 1120 bits were available. The GSM 7-bit alphabet pressed every ordinary character into seven bits, making it possible to use exactly 160 characters.
German engineer Friedhelm Hillebrand examined postcards and telex messages and concluded that this length would be sufficient for most short messages. On 3. In December 1992, technology first proved its magic when Neil Papworth sent the words “Merry Christmas” from a computer to a mobile phone.
However, the legendary limit only applied when using the GSM 7-bit alphabet. If a message required 16-bit encoding like UCS-2, space shrank to just 70 characters. Longer texts were distributed over several SMS messages, with administrative data reducing the usable space per section to 153 and 67 characters, respectively. A technical emergency solution resulted in a worldwide ritual of abbreviations, numerical codes and messages as short as possible.

Which digital primordial being crawled through the ARPANET in 1971 and went down in history as one of the first self-distributing computer programs?
Erklärung: Creeper crawled through the ARPANET in 1971 and is considered the first known network worm. The experimental program ran on TENEX computers, migrated independently between the connected systems and left the legendary message “I’M THE CREEPER, CATCH ME IF YOU CAN!” ‘
Creeper was developed by Bob Thomas at BBN as an experimental network worm. He should migrate from computer to computer and delete his previous copy. However, due to a mistake, this clean-up did not always work and the controlled experiment became an annoying inhabitant of the ARPANET. Technically, Creeper was not a virus, as he did not infect existing files, but traveled through the network as a stand-alone program.
Shortly after, Ray Tomlinson wrote a second worm with Reaper, which tracked down and removed creepers on the network. This almost simultaneously created the first known network worm and one of the first programs to combat it – the digital race between malware and protection software had begun.
Wrong answer LoveLetter — The email worm, disguised as a love letter, only spread through malicious visual basic scripts in 2000 and infected millions of Windows machines worldwide.
Wrong answer Rabbit — A Rabbit or Wabbit duplicates on a single computer until memory and computing power are exhausted. It was not a network worm wandering through the ARPANET in 1971.
Wrong answer Heartbleed — Heartbleed was a serious vulnerability in OpenSSL’s Heartbeat extension in 2014. It could disclose memory contents, but it was not a self-distributing program.

What did Douglas C. Engelbart invent in 1963?
Erklärung: Douglas C. Engelbart developed the concept of Computer mouse in 1963. His goal was not just a new input device, but an entirely new way of working with information, text and graphic elements on a screen.
Engelbart sketched the concept in 1963, his employee Bill English built the first prototype in 1964 from wood. Two metal discs arranged at right angles detected the movement on the table top. The cable protruded like a tail from the small case – this gave rise to the name Computer mouse.
On 9 September In December 1968, Engelbart first introduced the device to a large audience in San Francisco. The presentation, later called Mother of All Demos, featured not only the mouse, but also hypertext, windows, word processing, joint document editing, screen sharing and video conferencing.
In just 90 minutes, Engelbart’s team presented a large part of the computer future that would only become a matter of course for the rest of the world decades later. The mouse was only the small wooden tool with which he opened the door to this future.

Which pill in The Matrix sends Neo down the rabbit hole?
Erklärung: The Red pill leads Neo into the rabbit hole and forces him to leave the artificial world of the Matrix. The blue pill, on the other hand, would have brought him back to his previous life, with no memory of the encounter with Morpheus or the truth behind his reality.
Within the film plot, the Red pill is more than a symbol. Morpheus describes it as part of a location program that interrupts Neo's input and output signal to the matrix. This allows the crew of the Nebuchadnezzar to locate his real body between countless human capsules and free it from the system.
The rabbit hole refers to Lewis Carroll’s Alice in Wonderland and is previously announced by the tattoo of a white rabbit. Morpheus does not promise Neo that the truth will be pleasant. It merely offers him the opportunity to see for himself how deep the rabbit hole reaches.
After taking it, Neo's mirror image dissolves, his artificial world collapses and he awakens for the first time in his real body. The most famous philosophical decision of the film is thus also an executable hack in the form of a pill.

Which abbreviations in e-mails are linguistically based on copies made with carbon paper?
Erklärung: The email fields CC and BCC already bear their origin in the name. CC means carbon copy and BCC means blind carbon copy. Both terms come from a time when copies were still produced mechanically with carbon paper.
Before copiers and e-mails, a sheet of carbon paper was placed between two typewriter pages. Each keystroke transferred the font to the underlying sheet and produced a carbon copy. An additional copy was made for a blind carbon copy, the receiver of which did not appear on the other copies.
In an e-mail, recipients receive an openly visible copy under CC. Addresses in the BCC field, on the other hand, remain hidden from the other recipients. As electronic messages displaced the typewriter, this office language migrated almost unchanged into the email headers. In every modern message there is still a linguistic imprint from the mechanical world of ribbon, paper and punch-throughs.
Wrong answer FTP — The File Transfer Protocol is used to transfer files between computers and does not designate a recipient group or copy of a message.
Wrong answer BTX — Bildschirmtext was an interactive online service of the Deutsche Bundespost. The abbreviation has nothing to do with carbon paper or with e-mail copies.

What digital blackmail worm could not spread in 2017 after a security researcher registered a cryptic domain?
Erklärung: A digital wildfire hit a single, absurdly long domain name in 2017. When a researcher registered it, WannaCry lost its advance – a built-in kill switch stopped further automatic distribution.
WannaCry was a ransomware worm that independently spread through a vulnerability in the Windows SMB protocol in May 2017. Infected systems encrypted files and demanded ransom, while the worm searched for other accessible computers. Within a short time, he met companies, hospitals and authorities in numerous countries.
The security researcher Marcus Hutchins discovered in the program code a query to a long, not yet registered domain. He registered them to investigate network traffic. As soon as the domain was reachable, the widespread variant ended its infection routine. The registration therefore acted like a kill switch and largely stopped its further automatic spread. Already encrypted computers were not repaired, and later variants could use other domains.
Maze was also ransomware, MyDoom an email worm and Melissa a macrovirus. The spectacular interplay between domain registration and stopped worm is clearly part of WannaCry.

WannaCry was a ransomware worm that independently spread through a vulnerability in the Windows SMB protocol in May 2017. Infected systems encrypted files and demanded ransom, while the worm searched for other accessible computers. Within a short time, he met companies, hospitals and authorities in numerous countries.
The security researcher Marcus Hutchins discovered in the program code a query to a long, not yet registered domain. He registered them to investigate network traffic. As soon as the domain was reachable, the widespread variant ended its infection routine. The registration therefore acted like a kill switch and largely stopped its further automatic spread. Already encrypted computers were not repaired, and later variants could use other domains.
Maze was also ransomware, MyDoom an email worm and Melissa a macrovirus. The spectacular interplay between domain registration and stopped worm is clearly part of WannaCry.

Which audio format is lossy due to its codec compression?
Erklärung: OGG Vorbis and MP3 (MPEG-1 Layer 3) are lossy audio formats. Their compression specifically removes components of the audio signal to produce significantly smaller files. The discarded information cannot be fully reconstructed later.
OGG Vorbis and MP3 (MPEG-1 Layer 3) use psychoacoustic models. They analyze which frequencies are obscured by louder signals or are hardly perceptible to human hearing. These components are simplified or completely removed. With sufficient bitrate, the difference is often inconspicuous, but mathematically the restored audio file no longer corresponds to the original.
MP3 became the engine of the early digital music revolution, making music collections, portable players and exchange over the Internet workable. Because of his patents and then license fees, Ogg Vorbis emerged as a freely usable alternative. Both formats pursue the same goal – to preserve as much perceived sound as possible with as little data as possible.
Wrong answer FLAC — FLAC stands for Free Lossless Audio Codec and compresses audio data without loss of information. After unpacking, exactly the same digital samples are created as in the original file.
Wrong answer WAV(PCM) — PCM stores the individual samples unchanged and usually uncompressed. The WAV format is a container, but the explicitly mentioned PCM variant works without losses.

What do you get when you decrypt the Matrix Code (Digital Rain) from [The Matrix]?
Erklärung: The matrix code cannot be decrypted into a coherent message. According to production designer Simon Whiteley, his surprising visual basis came from a Japanese sushi recipe, whose characters he took from a cookbook by his wife.
Whiteley scanned Japanese characters from the cookbook and turned them into their own font. The finished Digital Rain combines mirrored Katakana signs with Latin letters and numerals. The falling signs therefore do not give a fully legible recipe. The Japanese sushi recipe was the unexpected graphical template and not an encrypted message.
The green representation deliberately reminded of the phosphorus monitors of early computers. The opening sequence of the anime Ghost in the Shell is also considered an important visual influence on The Matrix. In the film, the constantly flowing code became the visible heartbeat of the simulated world.
From the signs of an ordinary cookbook, one of the most famous pictures in film history emerged. The Digital Rain became a symbol of cyberspace, hackers and artificial reality worldwide – although its origin was neither machine language nor a secret program.

Which virus shaped William Birkin’s early research at Umbrella long before his obsession with the G virus Raccoon City plunged into ruin?
Erklärung: Long before his obsession with G-Virus, William Birkin worked on Umbrella’s T virus. Together with Albert Wesker, he continued the research of James Marcus and developed new virus variants, which eventually gave rise to the feared Tyrant bioweapons.
The original T-Virus was developed by James Marcus from the progenitor virus and genome of leeches. William Birkin and Albert Wesker later took over large parts of the research. Birkin worked on improved strains such as the Epsilon variant, which helped Umbrella create ever more powerful bioorganic weapons and eventually the Tyrants.
However, the G virus was not a direct development of the T virus. Birkin discovered an independent mutation of the progenitor virus in the body of Lisa Trevor, who was abused for years. Their extraordinary ability to regenerate and change continuously became the basis of his secret G project.
When Umbrella tried to wrest his research from him in 1998, Birkin was gunned down by a team and injected the G virus himself. His subsequent transformation destroyed almost the entire unit. At the same time, containers with T-virus samples broke, the contents of which reached the sewers via rats. Two different viruses united in a single night to the sinking of Raccoon City.

What is a Rubik’s Cube?
Erklärung: Six colours, 26 visible components and more than 43 trillion possible positions make up the legendary Magic Cube. What looks like a simple toy is a mechanical masterpiece and one of the most successful patience games in the world.
Hungarian architect and professor Ernő Rubik developed the cube in 1974 to illustrate spatial movements and three-dimensional constructions to his students. After first twisting the levels of his prototype, he had to find out for himself how to restore the original color order.
Inside, a hidden axis cross holds the six immovable middle stones. Eight corner parts and twelve edge parts move around it. The apparent composite of 27 small cubes is therefore an illusion, because in the center there is no visible single cube, but the supporting mechanism.
Under the name Magic Cube, the invention first came on the market in Hungary. From 1980 it was sold internationally as Rubik’s Cube and triggered a worldwide boom. Mathematically, the cube has exactly 43. 252. 003. 274. 489. 856. 000 reachable positions. Nevertheless, each of them can be solved with a maximum of 20 perfectly selected moves, a limit known as God’s Number.
Wrong answer Bitten apple — The bitten apple is Apple’s world-famous logo. Designer Rob Janoff supplemented the bite in 1977 mainly so that the fruit was clearly recognized as an apple and not a cherry. The pun between bite and byte was, according to him, not an original intention.
Wrong answer Neuralyzer — The neuralizer comes from Men in Black. The flashing device erases or alters the memories of witnesses and thus belongs to the science fiction equipment of the secret organization.
Wrong answer Flux capacitor — The flux compensator is the central component of the Time Machine from Back to the Future. According to Doc Brown, it allows time travel once the DeLorean reaches a speed of 88 miles per hour.

For which first-person shooter was the modification [Counter-Strike] developed in 1999?
Erklärung: The Counter-Strike modification was originally developed in 1999 for the first-person shooter Half-Life. A free fan project by Minh Le and Jess Cliffe resulted in a tactical counter-design to the fast-paced arena shooters of that era.
Minh “Gooseman” Le had previously worked on Action Quake 2 and started Counter-Strike as a free recreational project based on Half-Life. Jess Cliffe took care of website, community and sound recordings. On 19 March June 1999 saw the first public beta.
Instead of science fiction, the modification offered short rounds, realistic weapons, asymmetrical mission targets and final death until the start of the next round. New versions were created in close exchange with the players. Maps, tactics and bug reports from the community continued to shape the game almost in real time.
Counter-Strike spread so rapidly that Valve hired the two developers and took over the rights to the project. Version 1 appeared in November 2000. 0 as an official product. A free fan project had surpassed its original host and became the foundation of one of the longest-lasting competition series in game history.

What godlike power does the legendary cheatcode IDDQD unleash in the original Doom?
Erklärung: In 1993, Doomguy transformed four letters into an almost unstoppable fighting machine: God Mode. Those who typed in IDDQD during the game received 100 percent health and became immune to almost every ordinary harm.
The letter string was originally a tool of the developers. Doom did not need a visible input field and console. The engine listened directly to the keyboard during the game and activated the cheat once the correct string was fully recognized.
The leading ID referred to id Software. DQD dates back to Delta-Q-Delta, a joking programming association that Doom developer Dave Taylor and two friends had invented during their college days. From a personal inside joke, this became one of the most famous cheat codes in game history.
Nevertheless, Doomguy did not become completely omnipotent. Certain deadly soils and a telefrag were even able to overcome the God Mode. On the notorious difficulty level Nightmare, the classic cheats were also deactivated. So even the godlike power of IDDQD had its limits in hell.

Which file format is always lossy?
Erklärung: Between old and new image formats, there is only one candidate whose expressly named variant irretrievably sacrifices image information: JPEG (DCT-based) exchanges perfect reconstruction for surprisingly small files.
In JPEG (DCT-based), the image is typically broken down into 8×8 pixel blocks and converted into frequency components with the discrete cosine transformation. The decisive lossy step is quantization: finer image information is graded coarser or completely discarded. After the decompression, therefore, only an approximation to the original pixels arises.
The addition “DCT-based” is important. The comprehensive JPEG standard describes not only the widespread loss-prone DCT methods but also a rarely supported predictive lossless mode. However, ordinary JPEG files from cameras, browsers and image programs almost always use the DCT-based variant.
GIF stores a maximum of 256 colors and does not have a full-fledged alpha channel, but only simple transparent or non-transparent pixels. However, the actual LZW compression of the existing pallet indices is loss-free. If a graphic already fits completely into this color palette and does not require graduated transparency, it can be stored as a GIF without further loss of information. Only the necessary reduction of a color-richer starting image would discard visible information. JPEG (DCT-based) thus remains the unambiguously always lossy answer.

What is a Williams tube also called a Williams-Kilburn tube?
Erklärung: The Williams tube, also called the Williams-Kilburn tube, was an early form of electronic RAM. It turned a cathode-ray tube, as it was later known from televisions, into a memory for programs and data.
An electron beam wrote dots and lines on the tube's screen. However, the information was not stored by the visible glow, but by electrical charges that remained on the surface. A metal plate in front of the screen detected these states and made the individual bits readable again.
Since the charges already disintegrated after about 0.2 seconds, all memory locations had to be constantly read and rewritten. This continuous refresh is reminiscent of the refresh of modern DRAM building blocks. The sensitive tubes had to be carefully adjusted and were later displaced by the more reliable magnetic core memory.
On 21 March In June 1948, a Williams tube held the Manchester Baby's first program. His only 17 commands sought the largest real divisor of 262. 144. After 52 minutes and about 3.5 million calculations, the machine delivered the correct result. A ghostly pattern of dots and strokes had brought an electronic program directly to life in memory for the first time.

Which early real-time computer was originally developed for a planned US Navy flight simulator?
Erklärung: The Whirlwind I was developed at MIT as a real-time digital computer for a planned US Navy flight simulator. Unlike the calculators of that time, he was not supposed to work off columns of numbers prepared for hours, but to react immediately to the input of a pilot.
During World War II, the U.S. Navy searched for a simulator whose instruments could respond to a pilot's control movements without noticeable delay. An initially planned analogue system proved to be too inaccurate and inflexible. The team around Jay Forrester therefore relied on a radically new digital computer that was to continuously process input and immediately generate suitable outputs.
Whirlwind I became operational in 1951, contained about 5. 000 vacuum tubes, weighed several tons and filled a large room. By this time, the Navy had already lost interest in the original flight simulator. The computer therefore never became the fully realized Navy simulator for which its development had begun.
However, the US Air Force recognized the huge potential of the machine. Whirlwind processed real radar data, displayed flight movements on screens and allowed operators to interactively select displayed targets. These experiments later developed into the gigantic SAGE air defense network, which connected radar stations and data centers over long distances.
Whirlwind also advanced the development of the fast and reliable magnetic core memory. The failed simulator project thus became the ancestor of interactive computers, networked radar systems and modern real-time processing.
Wrong answer Xerox PARC — Xerox PARC is not a single computer, but a research center founded in 1970. This led to groundbreaking developments such as the Xerox Alto, graphical user interfaces, Ethernet and object-oriented programming.
Wrong answer UNIVAC I — The 1951 delivered UNIVAC I was the first commercially produced universal computer in the USA. It was primarily used for statistics, administration and business data, but did not work as an interactive Navy flight simulator.
Wrong answer Programma 101 — Olivetti introduced the Programma 101 in 1965. The compact programmable desk calculator is considered an important precursor of the personal computer, but was created long after Whirlwind I.

Which keyboard layout patented in 1936 was specifically developed to enable higher writing speeds through shorter fingerstrokes?
Erklärung: With shorter fingerstrokes and frequent letters on the baseline, Dvorak should make typing faster and less tiring. The 1936 patented layout challenged QWERTY’s decades-long reign with a scientifically optimized arrangement.
August Dvorak and William Dealey studied letter frequencies, typical letter sequences and the movements of the hands when writing English texts. Frequently used signs they placed on the easily accessible basic series. In addition, a change between left and right hand should accelerate the writing flow as regularly as possible.
In the Dvorak layout, the vowels are predominantly under the left and frequent consonants under the right hand. This allows numerous English words to be written with alternating attacks. The fingers have to leave the basic series less often and theoretically travel shorter distances than with QWERTY.
Whether Dvorak is actually faster in principle remains controversial. Writing speed depends heavily on training, language, personal technique and experience. Exceptional records were also achieved with QWERTY. Clearly, therefore, is not a universal superiority, but the declared development goal to enable higher speed and better ergonomics.
Wrong answer QWERTY — QWERTY was created in the 19th century. century for English-language typewriters and was spread by Remington. The layout is the worldwide standard today mainly because of its historical dominance.
Wrong answer Colemak — Colemak was published by Shai Coleman in 2006. It optimizes frequent English letter strings, but retains many QWERTY positions and familiar keyboard shortcuts to make the switch easier.
Wrong answer Neo — Neo is a modern layout optimized especially for the German language. It distributes frequent German letters cheaply and offers several levels for special characters, navigation, mathematics and programming.

What is the name of the first YouTube video, uploaded by founder Jawed Karim on April 23, 2005?
Erklärung: The first YouTube video is titled Me at the zoo and was released on 23. April 2005 by co-founder Jawed Karim. In the inconspicuous clip, Karim stands in front of two elephants at the San Diego Zoo and speaks briefly about their exceptionally long trunks.
The clip, which is only 19 seconds long, was recorded by Karim’s school friend Yakov Lapitsky. No studio, no music and no big production – this incidental scene opened the age of worldwide user-generated videos. The title Me at the zoo seemed almost like a blueprint for YouTube: Every person should be able to share ordinary moments with the world without technical hurdles.
Later, Karim used the description of his historical video several times as a protest surface against YouTube’s own decisions. In 2013, he criticized the forced Google+ access for comments and in 2021 the abolition of publicly visible Dislike numbers. Thus, the first YouTube video also became the small blackboard of a founder who critically watched his own platform.

Which legendary DOS extender enabled countless 32-bit games to use Protected Mode and thus access memory above the conventional 640 KB limit?
Erklärung: Before countless DOS games, an inconspicuous lettering appeared that opened the door to larger worlds. DOS4GW.EXE brought 32-bit programs into Protected Mode, freeing them from the notorious limit of conventional DOS storage.
The classic MS-DOS worked in 16-bit real mode and provided programs with only a limited address space. Particularly notorious were the 640 KB of conventional memory, which had to accommodate drivers, sound software and other memory-resident programs in addition to the actual game.
DOS4GW.EXE was the special Watcom edition of the DOS/4G extender developed by Rational Systems. It switched compatible processors into the 32-bit Protected mode and provided the launched program with an environment in which much more memory could be addressed and modern 32-bit code could be executed.
The extender was distributed together with the Watcom C/C++ compiler and could be shipped with finished programs without additional license costs. This made it particularly attractive to game developers. Titles like Doom, Descent, Duke Nukem 3D, Warcraft II and Tomb Raider launched their big DOS worlds using this small executable.
The superimposed start banner therefore appeared on millions of screens. Many players considered DOS4GW.EXE to be part of the game, although in the background there was a universal link between DOS, processor and 32-bit application.
Wrong answer HIMEM.SYS — HIMEM. SYS is a memory manager for extended memory. Among other things, it made it possible to load DOS into the High Memory Area, but did not turn a game itself into a 32-bit protected mode application.
Wrong answer FDISK.EXE — FDISK is a tool for creating and managing disk partitions. It organizes disk structures and has no function to expand the memory available for games.
Wrong answer MSCDEX.EXE — MSCDEX extended DOS access to CD-ROM drives, working with a suitable hardware driver. It made optical disks available as a drive, but was not a DOS extender.

Which animal is largely responsible for naming conventions in programming languages?
Erklärung: The invisible Camel in the source code can be recognized by the capital letters, which protrude like humps from a composite name. This image gave CamelCase its name and made the spelling one of the most famous conventions of programming.
In CamelCase, several words are connected without spaces. The capital letters within the name are reminiscent of the cusps of a camel. If the first word starts small, one often speaks of lowerCamelCase, for example myVariableName. If the first word begins large, the variant is usually called UpperCamelCase or PascalCase.
Such conventions help to legibly structure variables, functions, classes and other identifiers, although spaces are not allowed in many programming languages. The Camel is therefore not technically involved in the execution of the code. It merely provides the memorable image for the characteristic capital letters in the name. Which variant is used depends on the respective language, the project and its style rules.
Erklärung: The invisible Camel in the source code can be recognized by the capital letters, which protrude like humps from a composite name. This image gave CamelCase its name and made the spelling one of the most famous conventions of programming.
In CamelCase, several words are connected without spaces. The capital letters within the name are reminiscent of the cusps of a camel. If the first word starts small, one often speaks of lowerCamelCase, for example myVariableName. If the first word begins large, the variant is usually called UpperCamelCase or PascalCase.
Such conventions help to legibly structure variables, functions, classes and other identifiers, although spaces are not allowed in many programming languages. The Camel is therefore not technically involved in the execution of the code. It merely provides the memorable image for the characteristic capital letters in the name. Which variant is used depends on the respective language, the project and its style rules.

What time seems to be frozen on Apple’s official iPhone product images like forever?
Erklärung: On Apple's iPhone pictures, time seems to stand still. Generation after generation, the display shows the same magical moment: 9:41 – a deliberately staged minute reminiscent of the unveiling of the first iPhone.
The time 9:41 appears for many years on official iPhone product images and in numerous presentations. Apple is planning big reveals so that the central product will be unveiled about forty minutes after a keynote. The clock in the prepared picture should correspond as credibly as possible to the actual time in the hall at this moment.
At the presentation of the first iPhone on 9. January 2007 showed presentation material partially 9:42 a.m. For later product images, Apple standardized the display on 9:41. The number is therefore not a constantly second-accurate documentation of a single historical recording, but part of a carefully controlled visual staging.
The historic minute is one of the most famous product revelations ever. Steve Jobs initially announced three devices in 2007 – a widescreen iPod, a mobile phone and an Internet communicator. Then he repeated the terms until the audience realized that it was a single device. On the first iPhone, the clock was still at 9:42. Later, Apple advanced its permanently staged product time to 9:41. Even the status bar became a carefully choreographed part of the show.

For which game did Microsoft write exclusive code in Windows 95 to bypass a memory error?
Erklärung: An error in the original SimCity did not force Maxis, but Microsoft to an unusual rescue operation. Windows 95 recognized the game and changed the behavior of its memory management especially for its process.
This was the case for Windows 3. x developed version of the first SimCity and not SimCity 2000. The game accessed a memory area after it had already released it. On Windows 3. x the earlier content was randomly preserved long enough, which is why the programming error was hardly noticeable in normal operation.
During the development of Windows 95, the behavior of the memory manager changed. Shared memory could be used more quickly elsewhere and SimCity crashed suddenly. Microsoft analyzed the problem and found that not Windows, but the game violated the rules of memory management.
Instead of making the millions of popular classics incompatible, Microsoft built a targeted exception. If Windows 95 recognized SimCity, the memory administrator worked in a special mode and did not immediately release affected areas for reuse. The incorrect access thus continued to meet the expected data.
This solution did not cure the original program error, but reconstructed the very conditions under which it had remained invisible. The effort shows how uncompromisingly Microsoft wanted to let old software run on Windows 95. A single game received its own small protection room in the operating system.

Which object has been computer graphics' most famous 3D reference model since 1975?
Erklärung: An inconspicuous Teapot became the Mona Lisa of computer graphics. Since 1975, the Utah Teapot has served as a touchstone for new rendering methods and continues to appear today in research papers, 3D programs, films and games.
The model originated at the University of Utah, one of the most important birthplaces of modern computer graphics. Computer scientist Martin Newell was looking for an everyday object whose shape was complex enough to test curved surfaces, lighting, reflections and shades. His wife Sandra suggested the teapot that was on the table at dinner together.
Newell traced the contours of the real Melitta teapot on millimetre paper and transferred the measured points to the computer by hand. From this data, a model of Bézier plots emerged. The body offered curves and different curvatures, while the handle, spout and lid provided additional challenges for new graphics techniques.
Newell made the model data available to other researchers. At a time when suitable digital 3D objects were rare and laborious to create, the Teapot spread quickly. Scientists were able to test different algorithms for illumination, texturing, reflections and ray tracing using the same model and compare their results directly.
The original computer model does not have a closed bottom and looks flatter than the real pot. The reason for the compressed form lay in the output devices of that time, whose image representation did not always use square pixels. Later representations adopted these proportions and made the digital deviation the world-famous silhouette.
A household item eventually became the unofficial “Hello World” of the 3D graphic. As a homage, artists and developers hide the Utah Teapot in movies, games and render demos to this day. Even in the animated film Toy Story, she appears as a small greeting to the history of the technique that made such pictures possible in the first place.

What did Microsoft call the operating system before it was renamed Windows?
Erklärung: Before Microsoft named its graphical user interface Windows, it was named Interface Manager. However, Microsoft marketing chief Rowland Hanson convinced Bill Gates to name the product after its most striking feature – the windows on the screen.
The name Interface Manager soberly described what the software should do: manage different programs via a graphical interface. However, Hanson thought it was cumbersome and realized that the simple term Windows made the product more understandable and at the same time could occupy an entire software category.
Microsoft announced Windows in November 1983 and promised the release for April 1984. In fact, Windows 1 appeared. 0 only on the 20th. November 1985. The name was known long before the product was finished. It was precisely this aggressive early marketing that probably saved Windows from going down in history as an interface manager.

For what particular clock speed from IBM, was a unique PC case button introduced?
Erklärung: The turbo button referred to the original clock speed of 4.77 MHz, with which the first IBM PC worked. Faster compatible computers could be slowed down to this historic pace so that older software continued to function properly.
Many early games and programs measured their processes not by an independent clock, but by the speed of their program loops. On a faster processor, these loops were processed correspondingly faster. Game characters, animations and even entire races could run at an absurd pace or become unplayable.
Contrary to its name, the turbo button did not technically make the computer faster. The turbo mode normally corresponded to the full intended performance, while the off mode artificially slowed down the computer. As an accelerator, however, the function could be marketed much more impressively.
The glowing MHz display on the case was also often an illusion. It did not measure the actual clock rate, but only showed two previously set with small jumpers or the abbreviations HI and LO. So the button actually changed the speed, but the dramatically illuminating numerals were often nothing more than carefully staged computer magic.

What was needed to operate the emergency release of a CD-ROM drive?
Erklärung: When power, motor or electronics failed, the CD-ROM drive was still a last purely mechanical escape route. A bent Paper clip fit exactly into the tiny emergency release and was able to free the trapped disc.
The small hole on the front of an optical drive does not hide an electric button. Behind this is a direct mechanical access to the locking or gear mechanism of the drawer. As a result, the emergency opening works even when the computer is switched off.
If a stretched Paper clip is pressed in carefully and straight, it moves a lever or part of the gearbox. The lock is released and the drawer jumps a few millimeters forward. It can then be slowly pulled out by hand.
Before the emergency release, the running gear should have come to a complete stop. With a rotating disc, a forced opening could damage the data carrier or the mechanism. Also, the clamp must not be inserted indiscriminately into other openings or pressed in with excessive force.
The fact that a curved piece of office supplies has the last control over a complex laser drive seems almost absurd. But it was precisely this simple mechanical fallback level that made the Paper clip the unofficial rescue tool of the PC world for decades.

Why is [111-1111111] a valid Windows 95 license key?
Erklärung: The legendary simple Windows 95 key 111-1111111 seemed like a bad joke – and still passed the test at that time. His secret was not magic, but a frighteningly weak equation: MOD 7 = 0.
For many Windows 95 product keys, the back block consisted of seven digits. To check, the installer added these digits. If the sum was divisible by seven, the block was considered formally valid. Mathematically speaking, the digit sum modulo seven had to give the remainder zero – that is exactly what MOD 7 = 0 describes.
For block 1111111, the sum is seven. It is divisible by seven without residue and therefore passed the test routine. The front three-digit block was treated according to other, also weak rules. As a result, numerous easily guessed combinations could be accepted. The method was not a modern cryptographic authenticity check, but was primarily intended to detect typos and obviously invalid inputs.
Windows 95 could not match the key with a Microsoft server, because an online activation did not exist yet. The entire test was located locally in the installation program and had to work even without Internet. Those who knew their few mathematical rules could therefore create unlimited valid keys. Only with Windows XP did Microsoft introduce the notorious product activation in 2001, where license keys and hardware information were compared with Microsoft. 111-1111111 is thus a relic from a time when a simple cross sum as gatekeeper for an entire operating system was sufficient.

What does the Konami Code stand for?
Erklärung: A seemingly magical keystring wandered through countless Konami games and became a legend far beyond their borders. The Cheat code ↑ ↑ ↓ → → → B A stands today like hardly any other input for secret bonuses and hidden power.
The classic input sequence is ↑ ↓ ↓ → → B A. It was created during the development of Gradius for the Nintendo Entertainment System. Developer Kazuhisa Hashimoto needed a quick way to test the difficult game and therefore built in a secret keyboard shortcut that gave the player powerful advantages.
The code became especially famous by Contra, where it unlocked additional lives. After that, he appeared in numerous other games and developed into a universal symbol of gaming culture. Today, developers hide the episode not only in video games, but also on websites, apps and technical products. The Cheat code is therefore more than just an input. It is a digital mark of recognition for those who have grown up with the secrets of classic games.

Which logo unites Norway and Denmark?
Erklärung: The Bluetooth logo unites Norway and Denmark as it goes back to the name of the Danish King Harald Bluetooth. Harald Bluetooth united in the 10. In the 19th century the two countries and introduced Christianity.
The character combines the runes for the letters H and B, the initials of the Danish king Harald Blauzahn. As the historical ruler united different parts of the country, Bluetooth was to connect different devices.
The name was used for wireless communications technology to symbolize the connection and collaboration between different devices, similar to how Harald united the country.
Originally, Bluetooth should not become the final name. Intel employee Jim Kardach suggested it in 1996 only as a provisional codename. For the market launch later “PAN” or “RadioWire” were planned. However, PAN was already occupied thousands of times and the brand review for RadioWire could not be completed in time. Thus, the provisional Viking name remained and spread faster than marketing could replace it.

Which symbol is nicknamed the 'spider monkey' in German?
Erklärung: From medieval trade to the first email, a small sign traversed the centuries. The German nickname Klammeraffe refers to the @ At sign, which today connects billions of digital addresses.
The exact origin of the @ At Symbols is not unambiguously clarified. A common theory sees a ligature from the Latin letters a and d for "ad", which means "at" or "to". Other historical uses arose in trade as a short form for quantities and prices.
In English-speaking business, a spelling like “7 items @ 2 dollars” meant seven pieces for two dollars each. Therefore, the character was already present on some typewriters and later on computer keyboards, although it was rarely needed in ordinary text.
In 1971, computer scientist Ray Tomlinson searched for a character that could clearly separate a user's name from his computer's name. The @ offered itself because it was available on the keyboard, hardly in names and could be read linguistically as “at”. User@computer became the basic pattern of modern email addresses.
Its shape inspired different nicknames worldwide. In German, this became the brace monkey, in other countries the sign is reminiscent of snails, elephant trunks, ducktails or cinnamon snails. A centuries-old trademark thus became perhaps the most famous symbol of digital communication.

What was the first webcam in the world, developed at the Laboratory for Computer Science at Cambridge University in England in 1991?
Erklärung: The first webcam guarded neither a high-security laboratory nor a secret machine. Their object of desire was a Coffee machine in the Trojan Room at the University of Cambridge, whose level the researchers wanted to control from the comfort of the workplace.
The coffee machine stood in a room of the computer laboratory, which employees from other parts of the building only reached via several hallways and stairs. It was especially annoying to arrive there and find an empty pot. In 1991, Quentin Stafford-Fraser and Paul Jardetzky aimed a camera at the machine.
The XCoffee program transferred a grayscale image with 128 × 128 pixels over the internal network. A small window appeared on the workstations, which was updated several times per minute. The researchers were able to see whether the path to the Coffee machine was worthwhile without having to leave their desk.
Initially, the camera was not a webcam, because their images remained within the local network. It was not until 1993 that Daniel Gordon and Martyn Johnson connected the image stream with the World Wide Web. From that moment on, the now famous Trojan Room Coffee Pot could be viewed from all over the world.
What began as a solution to the laziness of thirsty computer scientists became an early Internet attraction with millions of visitors. The camera impressively showed that the web could not only transmit text and static documents, but also regularly updated images from the real world.
On 22 March In August 2001, the transfer ended after ten years. The coffee machine subsequently arrived at an online auction for 3. £350 to Spiegel Online. Today it is located at the Heinz Nixdorf MuseumsForum in Paderborn and reminds us that one of the most consequential image transmissions on the Internet began with the most important question of an office day – Is there still coffee?

Which domain was the first globally registered in 1985?
Erklärung: The first worldwide registered. com-Domain was symbolics.com, which was released on 15. March 1985 by Symbolics, Inc. , a manufacturer of computers, was registered. This domain marks an important milestone in the history of the Internet.
Symbolics built highly specialized Lisp machines for the research on artificial intelligence at that time. When the company registered the address, the public World Wide Web did not yet exist and no one suspected what value short domain names would once have. Symbolics computers largely disappeared, but their address survived. 2009 became Symbolics. com is sold and is still accessible today – as a digital fossil from a time before the modern Internet.

According to a well-known legend, which error code is associated with a disappeared room at CERN?
Erklärung: According to a famous Internet legend, 404 - Not Found hides a disappeared room at CERN. The story sounds like a perfect digital mystery, but there is no reliable historical evidence for this origin.
The legend tells of a room with the number 404 at CERN, in which requests for files are said to have been processed. If a requested document could not be found, the message Room 404 File Not Found was reportedly returned. This story spread excellently because it gave the most famous error code of the Internet a mysterious birthplace. However, it is not historically proven.
In fact, 404 - Not Found follows the systematic structure of HTTP status codes. The first digit 4 indicates an error on the side of the request or client. Within this group, 404 indicates that the server is reachable but cannot find the requested resource at the accessed address. So the code is not a monument to a lost CERN space. Precisely because the legend sounds so believable and charming, it is nevertheless one of the longest-lasting myths in the history of the World Wide Web.

Which computer released in 1981 made the commercially successful portable all-in-one computer known worldwide?
Erklärung: A weight of around eleven kilograms, a tiny screen and a case like a heavy sewing machine – the Osborne 1 was hardly a laptop in today’s imagination. Nevertheless, in 1981 he made the fully transportable workplace a commercial success for the first time.
The computer designed by Adam Osborne combined screen, keyboard, two disk drives and all the computing technology in a transportable housing. For working, the keyboard attached to the front was removed. The device did not have a battery, which is why it always needed an outlet despite its carrying handle.
Inside it worked a Zilog Z80 processor with 64 KB memory and the operating system CP/M. The screen, just five inches in size, could only represent a small section of a full line of text. For longer work, however, an external monitor could be connected.
His real sensation was the extensive software package. WordStar, SuperCalc, Microsoft BASIC and other programs were already included in the purchase price. The value of this software was almost at the level of the entire computer. For business travelers, the Osborne 1 became a complete office that could be transported between two locations.
The Osborne 1 was not the first portable computer at all and did not have the later foldable laptop form. Previous systems such as the IBM 5100 were already mobile. Its historical significance lies in the successful overall concept of a comparatively inexpensive computer, supplied software and a housing that was actually intended for regular transport.
Wrong answer Gavilan SC — Released in 1983, Gavilan SC was an early battery-powered folding computer and was marketed explicitly as a laptop. However, it appeared two years after Osborne 1.
Wrong answer GRiD Compass 1101 — The GRiD Compass, released in 1982, shaped the modern laptop shape with its flat screen and foldable case. Because of its enormous price, it was mainly used by the military, authorities and NASA.
Wrong answer Compaq Portable — The Compaq Portable appeared in 1983 and became a huge success as a largely IBM PC-compatible portable computer. Like the Osborne, however, it was a heavy luggable and not a light laptop.

His real sensation was the extensive software package. WordStar, SuperCalc, Microsoft BASIC and other programs were already included in the purchase price. The value of this software was almost at the level of the entire computer. For business travelers, the Osborne 1 became a complete office that could be transported between two locations.
The Osborne 1 was not the first portable computer at all and did not have the later foldable laptop form. Previous systems such as the IBM 5100 were already mobile. Its historical significance lies in the successful overall concept of a comparatively inexpensive computer, supplied software and a housing that was actually intended for regular transport.
Wrong answer Gavilan SC — Released in 1983, Gavilan SC was an early battery-powered folding computer and was marketed explicitly as a laptop. However, it appeared two years after Osborne 1.
Wrong answer GRiD Compass 1101 — The GRiD Compass, released in 1982, shaped the modern laptop shape with its flat screen and foldable case. Because of its enormous price, it was mainly used by the military, authorities and NASA.
Wrong answer Compaq Portable — The Compaq Portable appeared in 1983 and became a huge success as a largely IBM PC-compatible portable computer. Like the Osborne, however, it was a heavy luggable and not a light laptop.

What is colloquially a network of many computers that led to social events?
Erklärung: The term LAN party refers to an association of many computers over a local area network (LAN), where players often gather for social events to play video games together.
These events were especially popular in the 90s and early 2000s, as internet connections were often not fast enough to play online at the time.
It is always discussed which event was the first e-sports tournament. However, most agree that the 1980 National Space Invaders Championships were the first major competition tournament. The event drew around 10. 000 people and established competitive gaming as a real hobby. Stanford University’s 1972 Spacewar tournament was an important step in the field of competitive video gaming, allowing others to follow suit with their own events. One of the first major tournaments was “Battle by the Bay” – a Street Fighter LAN in California. 40 people took part in the first event and the tournament developed into what is now known as EVO.

Which military-funded computer network laid a crucial foundation for today’s Internet?
Erklärung: From 1969 onwards, the ARPANET connected for the first time far apart research facilities via a packet-switched network. From this initially small and militarily financed experiment grew a decisive precursor of today's Internet.
The ARPANET was established on behalf of the Advanced Research Projects Agency of the US Department of Defense. On 29 March In October 1969, the word LOGIN was first transmitted between UCLA and the Stanford Research Institute. After the first two letters, the system crashed. With LO, however, a new era of networked computers began.
The decisive factor was packet switching. Data was not sent as an uninterrupted stream over a fixed line, but was broken down into individual packets that could reach their destination via different routes. Later, the ARPANET was converted to TCP/IP. This protocol family forms the technical foundation of the Internet to this day. The World Wide Web is different from this. It was only developed by Tim Berners-Lee at CERN in 1989 and uses the already existing Internet as an infrastructure. The ARPANET thus laid a decisive foundation for the Internet, not directly for the World Wide Web.

What term in computer graphics describes the visual effect of light rays shining through atmospheric particles?
Erklärung: In computer graphics, the term God Rays describes the visual effect of light rays shining through atmospheric particles such as dust or fog. This effect is often depicted as a ‘light grid’ and contributes to a dramatic and realistic depiction of scenes.
God Rays become visible when light passes through openings and is scattered to dust, fog or other particles. In computer graphics, this atmospheric impression is usually reproduced by volumetric illumination.
In the real world, solar rays are almost parallel. That they diverge in the sky like a huge fan is a delusion of perspective – similar to railway tracks that seem to meet on the horizon. Clouds or buildings cast long shadows into the air filled with particles. Games used to fake this effect with radial softening, while modern engines can spatially calculate light scattering through fog and dust.

What does the codename SST-1 of the first Voodoo Graphics stand for?
Erklärung: The codename SST-1 of the first Voodoo Graphics card stands for Smith, Sellers and Tarolli, the founders of 3Dfx Interactive, the company behind the Voodoo card. This early graphics accelerator card revolutionized 3D graphics in computing and ushered in a new era for PC games.
Scott Sellers, Ross Smith and Gary Tarolli had previously worked on costly graphics technology for Silicon Graphics. In 1994, with the support of investor Gordon Campbell, they founded their own company to bring the performance of professional workstations to affordable PCs. The letters SST were thus not a sober technical abbreviation, but the initials of their last names. With SST-1, the three developers immortalized themselves right in the heart of Voodoo Graphics and SST-2 carried their signature further into the next generation.

Which gaming graphics card is the only one ever to switch between 2D and 3D mechanically via a relay?
Erklärung: A clear click announced that the PC left its normal surface and switched to the accelerated 3D world. The Orchid Righteous 3D switched the VGA signal path with a real mechanical relay, making the beginning of a game audible.
The Orchid Righteous 3D released in 1996 was based on the first 3dfx Voodoo Graphics chipset. This accelerator mastered only 3D graphics and could not represent the Windows desktop or ordinary two-dimensional applications. Therefore, a separate 2D graphics card remained installed in the computer.
A short VGA cable led the image signal from the existing graphics card to the Righteous 3D. From there, it reached the monitor via a second port. In normal operation, the voodoo card merely sneaked through the foreign 2D signal. Started a supported Glide game, she took over the image output herself.
The relay did not switch the calculation of a single graphics chip between 2D and 3D. It alternated the analog signal path between the output of the normal graphics card and the 3D image generated by the Voodoo hardware. It was precisely this mechanical change that caused the characteristic click.
Other manufacturers often switched their Voodoo cards electronically and almost silently. In the Orchid Righteous 3D, on the other hand, the relay became an unintentional acoustic trademark. Even before the 3dfx logo lit up, the player knew that Tomb Raider, GLQuake or another accelerated game was taking command of the monitor.
A sober component thus became a ritual of the early 3D era. The click was the mechanical moment when the grey office PC turned into an arcade machine for many owners.

Why are real mirrors in computer games still a huge mystery today – and what elaborate procedures make them work at all?
Erklärung: Mirrors seem self-evident, but for a game engine they are a rift in reality: suddenly the world has to exist from a second perspective. Only Second Game World or Real-time raytracing solve this mystery convincingly.
Classic raster graphics calculates a scene from the perspective of the game camera. However, a real mirror requires information about objects that are behind the player and may not appear at all in the current image. The engine therefore has to calculate additional geometry, lighting, shadows, animations and effects – often almost like a second complete image.
In the Second Game World solution, the scene is rendered again via a mirrored camera. Some games actually duplicate spaces, figures or relevant parts of the environment behind the mirror surface. The result is either visible directly through a correspondingly constructed mirror world or is first rendered into a texture and then displayed on the mirror surface.
Especially in first-person games, a complete player model must often be created especially for the mirror image. The normal camera often shows only separately rendered hands and weapons, while head, body and animations from your own perspective are not completely present.
Real-time raytracing tracks reflected rays from the mirror surface back into the virtual scene. As a result, objects that are outside the normal camera image can also become visible. For each reflected image point, however, further beams, materials, light sources and possibly additional reflections must be calculated. Especially large or several mirrors can thereby considerably increase the computing effort.
Wrong answer Anisotropic filtering — Anisotropic filtering improves the sharpness of textures viewed at a flat angle. Distant soils and roads thus appear clearer, but a second perspective or a mirror image is not produced.
Wrong answer Ambient occlusion — Ambient Occlusion produces soft contact shadows in corners, joints and at contact points. The method amplifies the spatial depth of a scene, but does not calculate a reflected view of the game world.

What methods are used to get (unpredictable patterns) real random numbers (not pseudo-random numbers)?
Erklärung: Where mathematics produces only calculable consequences, chaotic nature provides real entropy. Lava Lamps with optical noise and Atmospheric noise transform hard-to-predict physical processes into random values.
In a wall made of Lava Lamps, a camera continuously captures the chaotic movements of the colored wax bodies. The smallest changes in temperature, flow, light and image sensor affect every recorded image. From this image data, entropy can be obtained, which is combined with other sources and cryptographically processed.
This principle became known by LavaRand and later by Cloudflare’s Lava-Lamp-Wall. The lamps do not immediately generate finished random numbers. Their hardly exactly reproducible image information serves rather as physical input data with which safe random number generators are fed.
Atmospheric noise is obtained with radio receivers from natural electromagnetic fluctuations. Lightning, electrical processes in the atmosphere and other physical influences generate an irregular signal. Services like RANDOM. ORGs convert such measured values into random data.
For cryptographic applications, physical entropy is usually not used unchanged. The measurement data can contain distortions or technical disturbances and are therefore processed, tested and processed by cryptographic methods into uniformly distributed random values.
Wrong answer Mersenne twister — The Mersenne Twister is a fast pseudo-random number generator with an extremely long period. Its consequences are completely deterministic and predictable in a known internal state, which is why it is not suitable for cryptography.
Wrong answer Monte Carlo simulation — A Monte Carlo simulation does not necessarily produce real random numbers itself. It uses many random or pseudorandom samples to approximate mathematical, physical or economic problems.

The first hard drive in the world [IBM 305 RAMAC] from 1956 had how much storage capacity?
Erklärung: The first hard drive in the world, the IBM 305 RAMAC, was introduced in 1956 and had a storage capacity of 5 megabytes. This hard drive was revolutionary as it offered for the first time a mass-stored technology that made it possible to quickly store and retrieve large amounts of data.
Inside the IBM 350, 50 iron oxide-coated aluminum discs each with a diameter of about 61 centimeters worked. The entire storage was as large as two refrigerators, weighed more than a ton and still only held 5 megabytes. A moving reading head hovered on an air cushion over the rotating plates and reached a data set in about 800 milliseconds. Whatever happened to 64? 1,000 punch cards could take hours, suddenly succeeded almost instantaneously. IBM appropriately marketed this new capability as “Miracle Memory” at the time.

Which early AI was already conducting seemingly human conversations in 1966, long before ChatGPT and company?
Erklärung: Long before ChatGPT created entire texts, few rules were enough to make people believe in a thinking machine. In 1966, ELIZA offered its users a linguistic mirror – revealing our willingness to attribute spirit to computers.
ELIZA was developed by Joseph Weizenbaum at MIT and published in 1966. The most famous script was called DOCTOR and imitated a non-directive psychotherapist. The program searched for keywords in inputs, converted sentence parts and responded with prepared patterns or queries.
ELIZA did not understand the importance of entertainment and had neither a world model nor today's generative language skills. Nevertheless, some users found the answers surprisingly personal. Weizenbaum was concerned about how quickly people attributed understanding and empathy to the program. This phenomenon is still called the ELIZA effect.
ELIZA was not the first AI program at all, research programs such as Logic Theorist emerged as early as the 1950s. However, it was one of the first widely known chatbots. Deep Blue played chess decades later, AlphaGo mastered Go and Siri became a modern voice assistant. The seemingly human conversations of 1966 clearly belong to ELIZA.

What was the original idea of YouTube?
Erklärung: Before YouTube became the stage for billions of videos, the platform was supposed to bring lonely hearts together. As Video dating platform she wanted to match people via personal clips – but at first almost no one wanted to appear in front of the camera.
The founders Chad Hurley, Steve Chen and Jawed Karim registered the domain YouTube. com on the 14. February 2005, on Valentine's Day. The early concept was reminiscent of a dating site where users should introduce themselves with short videos and look for potential partners. The slogan at the time was “Tune In, Hook Up”.
The problem was not the technology, but the yawning void on the platform. Hardly anyone wanted to upload a personal dating video. The founders are said to have even offered women money for an introduction video via Craigslist without arousing enough interest.
Instead of sticking to the original concept, they removed the thematic limitation. Users were now allowed to upload any videos and share them easily via a web link. Exactly this openness became the decisive idea. YouTube didn’t have to tell people what to film, just provide the easiest place to do it.
On 23 March In April 2005 Jawed Karim uploaded the first video with "Me at the zoo". The clip, only a few seconds long in front of the elephant enclosure of the San Diego Zoo, contained nothing spectacular and demonstrated the new freedom. Anyone could record an ordinary moment and make it visible worldwide.
The failed Video dating platform resulted in a universal video portal within a few months. In October 2006, Google announced the acquisition for $1.65 billion in shares. An idea for which hardly anyone wanted to be filmed at first turned into one of the most powerful media archives in history.

With what did John Draper (one of the first hackers in the world) enable phone phreaking to make free long-distance calls?
Erklärung: A free toy pipe from a cornflakes pack coincidentally hit the secret sound of the American telephone network. With the Whistle from a cereal box, John Draper was able to control a long-distance line and became the legend of phone phreaking as Captain Crunch.
The pipe was distributed in the 1960s as a promotional gift with Cap’n-Crunch breakfast cereals. When she closed one of her two holes, she produced a sound of about 2600 Hertz. It was precisely this frequency that certain American long-distance connections used as an internal control signal.
The telephone network at that time transmitted conversations and control tones via the same audio channel. A 2600-Hertz tone signaled to the switching system that a long-distance line was free. John Draper learned about the pipe from blind phone-phreaker Joe Engressia and began to systematically investigate the vulnerability.
The Whistle from a cereal box alone could not dial any telephone number. It initially manipulated the state of the pipeline. A so-called blue box subsequently generated further precisely tuned multi-frequency tones, with which switching commands and destination numbers could be transmitted.
An Esquire article made Draper’s story famous in 1971 and also gave Steve Wozniak and Steve Jobs the idea to build their own blue boxes. The two sold some devices and discovered that they could jointly develop and market technical products. Jobs later explained that without this adventure, Apple might never have existed.

Why does a compact disc measure exactly 12 cm in diameter and hold 74 minutes of audio?
Erklärung: One of the most famous stories in the history of technology combines the 74 minutes of a CD with the Length of Beethoven's Ninth Symphony. The idea is legendary, but historically controversial and not unquestionably proven as the sole reason for development.
When Sony and Philips jointly developed the audio CD standard in the late 1970s, they had to agree on dimensions, playing time and technical parameters. According to the most famous story, Sony insisted that a full performance of Beethoven’s Ninth Symphony would fit on a single disc without interruption. The standard is often a 74-minute recording under Wilhelm Furtwängler. This is said to have resulted in the combination of 12 centimeters in diameter and about 74 minutes of playing time.
As with many perfect tech stories, the reality is probably more complicated. Corporate interests, existing prototypes, technical reserves and the negotiations between Sony and Philips also played a role. Some participants later even contradicted individual parts of the Beethoven narrative. For the quiz, the Length of Beethoven's Ninth Symphony is therefore the sought-after legendary explanation. However, it should not be confused with a fully proven historical fact.

What is the Unix epoch date?
Erklärung: For Unix, modern time begins in the first second of 1970. The time 1. January 1970, 00:00:00 UTC forms the Unix epoch from which operating systems store time as a continuous number of elapsed seconds.
The first Unix versions were created at Bell Laboratories in the early 1970s. For internal timekeeping, the developers needed a fixed and easily predictable starting point. The beginning of 1970 was close to the origin of the system and eventually became a permanent reference.
A Unix timestamp contains the number of seconds since the 1. January 1970, 00:00:00 UTC. The value 0 denotes exactly the beginning of the epoch, the value 60 one minute later. Points before 1970 can be represented as negative numbers on systems with signed values.
Time zones initially play no role in the storage. The timestamp is based on UTC and is only converted to a local time zone for display. This allows the same stored value to appear on computers in Berlin, New York or Tokyo as a different local time, even though it describes the same worldwide moment.
However, the seemingly endless sequence of seconds carries a historical time bomb. A sign-laden 32-bit value is reached on 19. January 2038 at 03:14:07 UTC its maximum of 2. 147. 483. 647 seconds. At the next step, it can overflow and be interpreted as a date in December 1901.
Modern 64-bit time values shift this limit by many billions of years. However, older operating systems, control units and embedded facilities may still be affected by the year-2038 issue. So behind almost every invisible timestamp is a counter that has been ticking ever since that first second of 1970.

Which modern browser feature do we owe to the hidden !NETSCAPE2.0 Easter egg in Netscape Navigator 2.0?
Erklärung: In the binary data of countless animations, Netscape lives on until today. The invisible identifier NETSCAPE2. 0 introduced the repetition control, with which animated GIFs start again after their last image and run forever in the loop if desired.
The GIF89a format was able to store multiple frames with their own delay times in one file, thus representing simple animations. However, the original standard did not specify a universal method by which such an image sequence could be automatically repeated as often as desired.
Netscape added a so-called Application Extension Block. In this data block, the eleven-character long identifier NETSCAPE2. 0 stands, followed by a value for the desired number of repetitions. The loop value 0 means that the animation starts from the front without limitation after its end.
The string does not appear visible in the browser and does not have to be entered by hand. Graphics programs write them directly into the GIF file when exporting. The browser reads the extension block, recognizes Netscape's statement and thus controls the repetition of the contained individual images.
Although it was originally a proprietary extension and not an official part of the GIF89a specification, other browsers and graphics programs adopted the procedure. Netscape’s own solution thus became an unofficial standard that is supported almost everywhere to this day.
Netscape Navigator disappeared, the identifier remained. Every endlessly dancing pixel image and every incessantly circulating meme can therefore still bear the name of a 1995 browser. Play GIFs in the Loop is thus a living digital fossil from the early days of the World Wide Web.

Which game or games had a so-called boss key (boss screen)?
Erklärung: If the boss unexpectedly came around the corner, a keystroke saved the digital hero from unpleasant questions. Leisure Suit Larry (1987) and Moorhuhn 2 (2000) are among the games with such a legendary boss key.
A boss key was a handy feature in many PC games of the 1980s and 1990s, allowing players to instantly hide or minimize the game – such as when a supervisor unexpectedly entered the room. Especially well-known are titles such as Leisure Suit Larry (1987) and Moorhuhn 2 (2000), who used this trick in a creative way. In Leisure Suit Larry, a fake spreadsheet was displayed when Ctrl + B was pressed – but with the side effect that the game ended immediately, a tongue-in-cheek hint of the risks of secret gambling. Moorhuhn 2 offered a more modern variant: a deceptively real Word document appeared here, which gave the impression that you were busy with office work.

Which legendary website has preserved the wild charm of the 1990s unchanged until today?
Erklärung: Blinking stars, shrill colors and navigation as if from a digital time capsule: spacejam.com preserved the wild spirit of the web from 1996 and even decades later became the famous relic of an almost forgotten Internet era.
spacejam.com went online in 1996 as an official website for the movie “Space Jam”. Instead of minimalist surfaces and responsive tile optics, it offered star-studded backgrounds, small GIF graphics, nested areas and a navigation structured like a space map. It is precisely this design that makes it a prime example of the early commercial World Wide Web.
For many years, the historical appearance remained almost unchanged. When a modern main page was created for the later film "Space Jam: A New Legacy", the old version was still preserved as a historical version. “Unchanged” describes above all appearance and content, not necessarily every server detail or URL path.
Napster. Com, CNN. com and other early addresses were fundamentally rebuilt several times or changed their function. spacejam.com, on the other hand, became a digital fossil: a website that not only reports on the 1990s, but still feels like an immediate visit during this time.

Which movie shows a real Unix user interface (IRIX from Silicon Graphics) with the 3D file management FSN (File System Navigator)?
Erklärung: When Lex announces “It’s a Unix system, I know this” in Jurassic Park, she doesn’t look at an invented Hollywood surface. With Jurassic Park, the film actually shows FSN, an experimental 3D file manager for IRIX workstations from Silicon Graphics.
FSN stands for File System Navigator and was developed by Silicon Graphics as a three-dimensional visualization of a Unix file system. Directories appeared as platforms, files as columns of different heights and the folder structure as a walk-in virtual landscape. The size and position of the displayed objects conveyed information about the stored data.
In the film, Lex uses the surface to move through the park’s computer system and re-activate the door lock. For spectators of 1993, the scene seemed like a futuristic vision of hacking in a virtual world. In fact, real software ran in the background on the operating system IRIX from Silicon Graphics.
However, FSN was not a special security or control program for dinosaur parks. It was a technical demonstration to show how complex file structures can be represented spatially. Hollywood put the unusual surface in a dramatic context, turning an experimental file browser into a tool to save from velociraptors.
The scene has a fascinating second level. Silicon Graphics workstations were also behind the scenes among the critical tools used by Industrial Light & Magic to create the digital dinosaurs of film. The same computer world that brought the T-Rex to life on the screen appeared within the plot as the nervous system of the park.
Jurassic Park did not show a mere fantasy surface, but a real piece of Unix history. A little-known SGI demonstration turned into one of the most famous computer interfaces in cinema within a few film seconds.

On what mathematical basis is the original Tetris based?
Erklärung: The shapes of Tetris blocks (also called Tetrominos) come from mathematics, more precisely from the geometry of polyominos. A tetromino is a special type of polyomino consisting of exactly four square fields.
Russian developer Alexei Pashitnov, who developed Tetris in 1984, drew inspiration from Pentominos – five-square figures commonly used in puzzles. However, since these were too complex for a fluid gameplay, he reduced the pieces to four squares – the Tetrominos. This resulted in exactly seven possible forms: I, O, T, L, J, S and Z. Why is there only 7 Tetrominos in Tetris? In purely mathematical terms, there are actually 19 different Tetromino forms, even if one counts mirrored variants as independent forms. However, since Tetris does not distinguish reflections, but only allows rotations, the number is reduced to 7 unique shapes.

What controversial theory explains why the seemingly close SS Californian of the Titanic did not come to the rescue?
Erklärung: The lights of the SS Californian were almost within reach that icy night – but no help came. A controversial theory sees Atmospheric refraction of light as the invisible veil that distorted distance and signals.
In the night of the 14. to the 15. April 1912 could occur strong temperature differences between water and air. Such a temperature inversion changes the refractive index of the air layers. Light rays are curved, distant ships, horizon and signal lights can be raised, stretched, distorted or apparently displayed in more detail.
The Atmospheric refraction theory attempts to explain why Titanic and SS Californian crews may have misperceived distances, ship silhouettes and emergency missiles. The effect is often associated with a mirage occurring over the sea or Fata Morgana.
Tragedy involves a bitter temporal chain. The only Californian radio operator had previously warned the Titanic about the ice field, but stopped his device around 11:30 pm and went to sleep. Only about ten minutes later, the Titanic collided with the iceberg. Later, officers of the Californian observed several rockets, but did not clearly interpret their importance and did not immediately run to the aid. When the radio was occupied again in the morning, the Carpathia already rescued the survivors.

What makes Subsurface Scattering (SSS) realistic?
Erklärung: Light does not always end on the surface. In the case of Marble, Skin and Gummy bears, it penetrates into the material, is scattered inside and emerges again at another location. Only Subsurface Scattering gives them their soft liveliness.
With an ordinary opaque surface, light is directly reflected or absorbed. Translucence changes this process. Part of the light penetrates beneath the surface, is deflected several times by internal structures and leaves the material with changed direction and color. This behavior is called subsurface scattering.
In human Skin, light travels through several layers of tissue. Blood and other components affect its color. Especially on ears, fingers and nostrils the reddish scatter becomes visible. Without SSS, digitally rendered faces quickly look like rigid plastic or wax.
Marble scatters light in its fine crystalline structures and thus obtains its typical soft depth. In a Gummy bears, the light passes through the gelatin, distributes itself in the colored interior and emerges diffusely again. If you hold it in front of a bright lamp, the effect becomes immediately visible.
Titanium behaves fundamentally differently as a metal. Visible light does not penetrate far enough to produce a comparable scattering effect, but is predominantly reflected or absorbed at the surface. Therefore, only the first three materials are among the right answers.
For digital figures, SSS became a decisive step out of the Uncanny Valley. Modern renderers calculate or approximate the light migration below the surface, giving skin, wax, milk, jade and organic materials the depth that pure surface lighting could never produce.

What are the characteristic light patterns created by refraction or reflection on transparent or curved surfaces, such as the bottom of a swimming pool, called?
Erklärung: The dancing light on the floor of a swimming pool is not a random pattern. It is produced when curved surfaces focus light beams. In optics and computer graphics, these bright, often flickering structures are called Caustics.
When light strikes a moving water surface, each beam is deflected in a different direction depending on the angle of incidence and the refractive index of the water. Many of these refracted rays cross and condense in certain places. There, more light reaches the ground and the characteristic bright lines are created.
Caustics can occur not only by refraction, but also by reflection. A curved glass surface, a metal ring or the inside of a cup can deflect light so that luminous arcs, tips and focal lines become visible. The term is derived from the Greek word for burning and refers to the strong concentration of light energy.
Such patterns are particularly demanding for computer graphics. A renderer must track light paths which are first reflected or refracted on a specular or transparent surface and then impinge on a diffuse surface. Methods such as photon mapping or bidirectional path tracing can physically approximate these paths, but require considerable computing power.
In real-time games, Caustics are often faked with animated textures, projected patterns or specially calculated shaders. Modern ray tracing methods can calculate light paths more dynamically, but even there a compromise between accuracy, image noise and speed remains necessary.
Wrong answer Spectral Warp — Spectral Warp is not an established physical term for focused light patterns. The expression sounds like a spectral color or image distortion, but does not denote the optical effect sought.
Wrong answer Superfluidity — Superfluidity is a quantum physical state in which a liquid flows almost without internal friction. The phenomenon occurs at extremely low temperatures and does not explain light patterns on the pool floor.
Wrong answer Interference — Interference is caused by the superposition of waves and can produce light and dark stripes. Caustics, on the other hand, are mainly based on the geometric bundling of reflected or refracted light beams.

Which device is considered an early commercial smartphone precursor with a touchscreen?
Erklärung: In 1994, the IBM Simon combined telephone, touchscreen and digital organization into a single device. Long before the term smartphone belonged to everyday life, this heavy black harbinger already carried surprisingly many functions of a modern mobile phone.
IBM presented the prototype in 1992 under the name Angler. Two years later, the American mobile operator BellSouth launched the finished device as Simon Personal Communicator. It was operated via a monochrome touch-sensitive screen and a pen.
The IBM Simon could not only make calls, but also send and receive fax messages and e-mails. Calendar, address book, notes, calculator, world clock and a screen keyboard made it a connection of mobile phone and personal digital assistant. Additional applications could be loaded via a special memory card.
Elegant or enduring, the early messenger of the future was not. He weighed more than half a kilogram, was over twenty centimeters high and reached with his standard battery only about an hour of conversation time. The high price and limited mobile coverage also prevented widespread use.
The term smartphone became common only later. In retrospect, the IBM Simon is still considered one of the first commercial smartphone precursors and often even the first smartphone. He already showed in 1994 that telephone, computer and personal communication would one day merge into a single touchscreen device.
Wrong answer Apple Newton — The 1993 release of Newton MessagePad was an influential PDA with pen operating and handwriting recognition. However, he did not have a fully integrated mobile phone.
Wrong answer Nokia 9000 Communicator — Nokia’s 1996 Communicator combined telephone, email, fax and organizer. It was operated via keyboard and keys and did not have a touchscreen.
Wrong answer PalmPilot 1000 — The PalmPilot 1000 was released in 1996 as a compact PDA with touchscreen and handwriting graffiti. An own mobile and telephone function was not integrated.

What method tries to identify passwords by systematically trying out all possible combinations?
Erklärung: Brute force (raw force) aims to obtain access data such as passwords by automatically and systematically testing all possible character and word combinations. It does not exploit technical vulnerabilities or include human factors.
Brute force requires neither a convincing deception nor a particular vulnerability in an application. The attack wins only by computing power, time and the complete trial of the possible search space.
Social engineering uses the behavior or trust of people in order to obtain sensitive information – for example through personal manipulation. Phishing is a special form of this, where fraudulent emails or websites are used to trick users into revealing data. SQL injection attacks database systems by manipulated inputs exploiting vulnerabilities in the backend. In contrast, Brute force is based purely on endurance and computing power.

Which of these games used the classic shareware model and released a playable part for free?
Erklärung: Wolfenstein 3D, Doom and Jazz jackrabbit opened their first worlds for free. Via mailboxes, floppy disks and booklet CDs, the shareware versions spread like digital wildfire and made millions of players volunteer test pilots.
The shareware model allowed to legally copy and share a full playable part. If you wanted more, ordered the registered full version directly from the manufacturer. Without expensive store space or classic advertising campaigns, small studios could reach a huge audience.
Apogee Software perfected this principle with its episodic distribution model. The first part of a game was distributed for free, while more episodes were only available for payment. id Software used this infrastructure in 1992 for Wolfenstein 3D. The complete episode "Escape from Wolfenstein" was freely copied, two more episode blocks were sold.
With Doom shareware reached a new dimension at the end of 1993. The free episode “Knee-Deep in the Dead” spread across universities, mailboxes, corporate networks and countless floppy disks. The servers were temporarily completely overloaded when they appeared. Who wanted to continue the journey through hell, ordered the registered episodes directly at id Software.
Epic MegaGames also used this model at Jazz jackrabbit in 1994. The free episode “Turtle Terror” already presented the fast technology, colorful graphics and music of the game. Further episodes and adventures received buyers with the full version.
Half-Life appeared in 1998 as a regular commercial full-price game. The demo Half-Life Uplink, which was later released free of charge, was a specially compiled trial version and not a classic shareware chapter. This means that Wolfenstein 3D, Doom and Jazz jackrabbit are among the three correct answers.

Which of these display and visibility techniques still shape computer games today?
Erklärung: Two tricks from completely different game worlds survived entire hardware generations: Billboard lets flat images follow the eye, while Fog-of-War makes knowledge itself the most precious resource.
In the Billboard, a flat, textured surface is aligned in three-dimensional space in such a way that it always points towards the camera. As a result, a tree, a cloud of smoke, a glow of light or even a game character can appear spatially, although very little geometry is calculated. Early 3D games used this technique massively, modern engines continue to use billboards for vegetation, particles and distant objects.
Fog-of-War is not a classic rendering technique, but a display and visibility mechanic. Unexplored or currently unobserved areas of a map are hidden or darkened. Strategy games thus create uncertainty: the player only knows what his units actually reveal.
Token ring is a historical network method in which a token passes on the sending authorization within a ring. A zero-day exploit refers to the exploitation of an unresolved vulnerability. Both terms belong to computer technology, but do not shape the image of modern games as presentation or visibility techniques.

Why can many CDs or DVDs often still be played flawlessly even with heavy scratches?
Erklärung: Under the shiny surface of a disc works a mathematical safety net. Reed Solomon codes distribute additional information so that a drive can reconstruct numerous damaged or unreadable data locations.
Imagine data being like cars traveling on a highway – but not just wildly scattered, but following a fixed, mathematically defined path: a so-called polynomial. If a few “cars” are lost during transmission or storage (e.g. B. through a scratch on the CD, the system can still recognize the original path – and fill the gaps mathematically, because the course of the road (i.e. the polynomial) is known. This is the basic principle of Reed Solomon coding: You know what the data path has to look like – and can easily calculate missing pieces.
If a CD or DVD is played flawlessly despite visible scratches or dirt, it is no coincidence – it is mathematics in action. More specifically: Reed-Solomon coding, a method of error correction based on the idea of representing data through polynomials and protecting it with redundancy. However, these polynomials do not work in the normal number space, but in a special mathematical world – the so-called Galois fields. In these finite number systems (e.g. B. With only 256 possible values, calculation rules behave differently – but that is exactly what makes them perfect for the digital world: every step of calculation remains clear and lossless.
At its core, Reed-Solomon works like this: The original data (e.g. B. Music or video data are packed into a polynomial and then evaluated in several places – more than you would actually need for the recovery. These additional points do not contain any new information, but are purely mathematically derivable – and precisely they make it possible to reconstruct the original polynomial later on even if part of the values has been damaged or lost. For example, a CD player can simply “overcompute” a scratch instead of stopping.
What makes Reed-Solomon so groundbreaking is its ability to handle arbitrary errors at the symbol level (e.g. B. correct whole bytes – not just individual bits. In addition, the method is deterministic, works without assumptions about the error – and does not need repetitions or queries like other coding types. It is an extremely robust solution for unstable transmission media.

This is the basic principle of Reed Solomon coding: You know what the data path has to look like – and can easily calculate missing pieces.
If a CD or DVD is played flawlessly despite visible scratches or dirt, it is no coincidence – it is mathematics in action. More specifically: Reed-Solomon coding, a method of error correction based on the idea of representing data through polynomials and protecting it with redundancy. However, these polynomials do not work in the normal number space, but in a special mathematical world – the so-called Galois fields. In these finite number systems (e.g. B. With only 256 possible values, calculation rules behave differently – but that is exactly what makes them perfect for the digital world: every step of calculation remains clear and lossless.
At its core, Reed-Solomon works like this: The original data (e.g. B. Music or video data are packed into a polynomial and then evaluated in several places – more than you would actually need for the recovery. These additional points do not contain any new information, but are purely mathematically derivable – and precisely they make it possible to reconstruct the original polynomial later on even if part of the values has been damaged or lost. For example, a CD player can simply “overcompute” a scratch instead of stopping.
What makes Reed-Solomon so groundbreaking is its ability to handle arbitrary errors at the symbol level (e.g. B. correct whole bytes – not just individual bits. In addition, the method is deterministic, works without assumptions about the error – and does not need repetitions or queries like other coding types. It is an extremely robust solution for unstable transmission media.

What led to a lengthy legal battle behind the scenes in the X-Files?
Erklärung: Over Mulder’s desk hung not only a symbol of his faith, but also an unresolved rights problem. The legendary “I Want to Believe” poster used a UFO photo without clarified permission, triggering a dispute behind the scenes.
The motif was based on a recording of the Swiss UFO contact Eduard “Billy” Meier. Meier claimed to have repeatedly photographed alien spacecraft since the 1970s. His pictures mostly show silver, disc-shaped objects over rural landscapes and became world famous within the UFO scene.
The authenticity of these recordings is strongly doubted. Critics came to the conclusion that numerous motifs could have been staged with small models and ordinary household objects. However, this mixture of apparent proof, persistent doubt and indissoluble legend perfectly matched the world of the X-Files.
Serial creator Chris Carter had one of the images used for the “I Want to Believe” poster. According to his later statements, however, the required image rights had not been properly clarified. This resulted in a legal dispute, which led to the fact that the original UFO motif had to be replaced by a redesigned variant.
The poster already hung in Mulder’s basement office in the pilot film and became a visual summary of his character. Mulder didn’t just want to blindly believe in aliens. He was looking for proof of something outside the officially accepted truth. The sentence therefore expressed hope and doubt at the same time.
Although the picture was changed, the message persisted and even survived the series. The “I Want to Believe” poster became a worldwide symbol of UFO culture, conspiracies and the human desire to discover a greater truth behind the visible.

What mysterious number made real-time 3D graphics the game development revolution through faster vector calculations?
Erklärung: Between ordinary program code, a number lit up like a digital magic word. 0x5F3759DF enabled an extremely fast approximation of the inverse of a square root and became legendary through the source code of Quake III Arena.
In 3D graphics, direction vectors often have to be normalized and thus brought to length 1. For this, the reciprocal of its length is required, i.e. mathematically a calculation of the form 1 divided by the square root of a number. On processors at that time, this operation could be comparatively expensive.
The Fast Inverse Square Root initially treated the bit representation of a 32-bit floating point number as an integer. After a shift, the value was subtracted from the magic constant 0x5F3759DF. The result already provided an amazingly good first approximation for the reciprocal value sought.
Subsequent iteration of the Newton-Raphson method significantly improved accuracy. The trick thus linked the internal structure of the IEEE 754 floating point format, a carefully chosen constant and a classical mathematical approximation method.
The code became famous by the publication of the Quake III source code, but the basic principle was not invented there. Its prehistory includes several developers and earlier 3D systems. An important origin is often mentioned Greg Walsh at Ardent Computer, while Gary Tarolli later used the technique at 3dfx and passed it on.
Modern processors have fast square root, reciprocal and vector instructions, so the historical trick today is not automatically faster. Nevertheless, 0x5F3759DF remains a monument to an era in which few bit operations could make the difference between mathematical elegance and fluid real-time graphics.

How do open-world games solve the precision problem of the 32-bit coordinates and the trembling far away?
Erklärung: The further away a game piece is from the origin, the coarser the number grid of their 32-bit world becomes. At some point, models begin to tremble and collisions begin to disintegrate. The abstract Gliding carpet therefore draws the entire world back among the players.
Many real-time engines store positions as 32-bit floating point numbers. These have only a limited number of significant positions. Close to the coordinate origin, representable values lie very close together. With increasing distance, however, the distances between two possible numbers become ever larger.
Small position changes can then no longer be stored precisely. Objects tremble, animations jump, surfaces flicker and physical calculations become unstable. Especially huge open worlds, space games and flight simulators reach the limits of a single global coordinate system.
With the principle Gliding carpet, the player remains computationally close to the origin. If it exceeds a specified distance, the engine moves the world coordinates or resets the origin. For the player, the journey continues unchanged, but internally the entire world is withdrawn under him again and again.
The technical terms are Floating Origin or Origin Rebasing. The implementation is demanding, because not only visible models have to be moved. Physics objects, particles, AI, audio sources and network states must also perform the same jump consistently. Modern engines partially combine this process with 64-bit coordinates or camera-relative rendering.
Wrong answer Möbius band — A Möbius band is a surface with only one side and a single edge. It is created by twisting and joining a strip, but does not solve numerical precision problems.
Wrong answer Mandela effect — The Mandela effect refers to the phenomenon that many people share the same false memory. It belongs to the culture of perception and remembrance and has no relation to coordinate calculation.
Wrong answer Penrose staircase — The Penrose Staircase is a geometrically impossible figure whose steps lead seemingly endlessly upward. It is based on an optical illusion and does not shift the origin of a game world.

Why are floppy disks called 'floppy'?
Erklärung: The name comes from a time when data carriers were still visibly soft and flexible. Early floppy disks were only in a thin shell and They were bent. — so in English they were actually “floppy”.
Inside a diskette is a circular disc made of flexible plastic, which is coated with magnetizable material. During reading and writing, this thin medium rotates in its envelope while the read/write head scans or changes the stored magnetic information.
The first disks developed by IBM had a diameter of eight inches. Its outer shell consisted only of thin plastic and could be easily bent together with the magnetic disc. The later 5 1⁄4-inch disks used the same flexible basic principle and made the name Floppy Disk known worldwide.
With the 31⁄2-inch disk, the visible structure changed. A stable plastic shell and displaceable metal protection protected the sensitive surface from contact and damage. However, the magnetic storage medium inside remained a thin and flexible disk.
The term floppy disk therefore survived the change to the rigid housing. Even the robust 31⁄2-inch version continued to bear the name of its bendable ancestors. While hard drives stored their magnetic disks on rigid disks, the actual disk of a floppy remained soft enough that they could clearly bent, without their protective shell.

Which phone had a built-in mechanical hard drive instead of flash memory?
Erklärung: At a time when flash memory was still precious, the Nokia N91 carried a tiny rotating hard drive in the metal case. The 2005 music smartphone saved four gigabytes on a real 0.85-inch Micro HDD.
Inside worked a Toshiba MK4001MTD. Despite its extremely small dimensions, it had the classic components of a mechanical hard drive. A magnetic disc rotated at high speed while a tiny read-write head was positioned above its surface.
For Nokia, the unusual setup was a response to the storage prices of the mid-2000s. NAND flash with several gigabytes was still expensive, while miniature hard drives already enabled large capacities in music players. The Nokia N91 should store thousands of songs and act as a serious competitor to the iPod.
Own playback buttons, a headphone jack, WLAN and support for various audio formats underlined this claim. Later even appeared a version with eight gigabytes of hard disk space. For a mobile phone of that time, that was an extraordinary capacity.
However, the movable components had disadvantages. The hard drive required more energy, generated heat, was more sensitive to shocks and took time to start up. In addition, you could partially hear or feel their activity in the device.
With rapidly falling prices and increasing capacities of NAND-Flash, the mechanical hard drive disappeared from mobile phones again. The Nokia N91 thus remained a fascinating technical side way – a smartphone that did not read its music silently from memory chips, but fetched it from an actually rotating magnetic disk.

Which of these encryption methods is considered the most powerful bulwark for symmetric encryption under today’s standards?
Erklärung: Between ancient letter shifts and modern cryptography, an almost impregnable bulwark arises. Among the methods mentioned, AES-256 bit offers the strongest modern symmetric encryption.
AES-256 bit is the variant of the Advanced Encryption Standard with a 256-bit key. AES is a symmetrical block cipher: the same secret key is used for encryption and decryption. The data is processed in 128-bit blocks, with AES-256 it goes through fourteen rounds of replacements, shifts, mixing operations and round keys.
A complete trial of all 2256 keys is practically excluded with today's technology. Nevertheless, real security depends on more than the key length: operating mode, random values, key management and implementation must be correct. “The best” method does not exist independently of the intended use, but among the answers offered, AES-256 bit is clearly the strongest contemporary symmetrical choice.
RSA-2048 is asymmetric and cannot be compared to AES by its larger bit count alone. Blowfish is symmetrical but has a problematic block size of 64 bits today. The Caesar Cipher merely moves letters and can be broken in seconds.

What word arises when “OLIH” is decrypted with Caesar-Shift 3?
Erklärung: Behind the four shifted letters there is no random product, but the decrypted word LIFE. The Caesar shift traces each letter back three positions in the alphabet and resurrects the original message.
In Caesar encryption, each letter in the alphabet is moved by a fixed number of positions. In this case, the displacement is 3 digits. To find the original word, move each letter of OLIH back three digits in the alphabet. Here, O→L, L→I, I→F and H→E are used. This gives the original word LIFE. Caesar encryption is a very simple method in which there are few possible shifts, which is why it no longer offers real security today and is mainly used for demonstration or learning purposes.
The name of this cipher leads directly to ancient Rome. Julius Caesar is said to have used them for confidential military intelligence, while Emperor Augustus used a similar variant with only one-digit displacement. Her modern descendant ROT13 later hid points, solutions and spoilers in Internet forums. What was once intended to secure campaigns became a digital game of hide and seek thousands of years later.

What is symbolic of a typical problem in shadow calculations in computer games?
Erklärung: When a shadow loses contact with his object, the figure suddenly seems to float above the ground. This classic artifact bears the fairytale name Peter Pan effect and is created by too much distance in the shadow calculation.
The Peter Pan effect describes a problem in shadow calculations where objects seem to float above the ground because the shadow is easily displayed offset from the object. The cause is usually too large a depth bias, which is actually used to avoid shadow acne. Shadow acne is caused by rounding errors in depth calculation and shows itself as flickering, point-like shadow artifacts on surfaces. To reduce these, a bias is added that minimally shifts the shadow. However, if this bias is too strong, the shadow is visibly detached from the object – the Peter Pan effect is created. The challenge is to choose a suitable bias that minimizes shadow acne without making the shadow look unnatural.

Which monster hid in the legendary “Mercury Brick” of Quantum3D?
Erklärung: The Mercury Brick was no ordinary graphic accelerator, but a monumental cuboid full of voodoo magic. Four Obsidian2 cards combined eight Voodoo2 chipsets into one of the most spectacular graphics systems of its time.
Quantum3D was created in 1997 as a financially independent spin-off of 3dfx. The company adopted the professional Obsidian product line and took the scalable Voodoo technology to where performance was more important than price, power consumption or board length. These included arcade systems, industrial visualisations and civil and military simulators.
The highlight of this technical megalomania was the Mercury Brick. The system connected four massive Quantum3D Obsidian2 200SBi. Each of these cards already carried two complete Voodoo2 chipsets in the SLI network. Throughout the setup, eight Voodoo2 chipsets and a total of 96 megabytes of graphics memory worked.
The four Obsidian2 maps produced slightly offset image scans in parallel, which were then combined to form a smoothed overall image. The enormous computing power therefore not only served a higher speed, but above all an unusual full-scene edge smoothing by the time. The massive construction was quite rightly named Mercury Brick because of its shape.
While 3dfx went down in 2000 and its main assets were sold to Nvidia, Quantum3D survived. The company then moved from Voodoo to Nvidia technology and continued to focus on professional simulation and training systems. Some of the original 3dfx DNA lives on until today.

Which company was about to change the world forever in 1996 – and only four years later became a legend itself?
Erklärung: In 1996, 3dfx Interactive opened a portal into a new era with Voodoo Graphics. Suddenly, the PC no longer looked like a gray work tool, but like an arcade machine – and for a short, magical moment, this young company seemed to own the entire 3D future.
3dfx Interactive was born in 1994 from the vision of Scott Sellers, Ross Smith and Gary Tarolli. They knew that even brilliant technology without games remained meaningless. Their plan was bold: a scalable 3D platform would first conquer the arcade world and then bring almost identical gaming experiences to PC.
In October 1996, Voodoo Graphics reached the market. The additional card calculated exclusively 3D and was connected via a loop-through cable to the existing 2D graphics card. But once a supported game started, magic happened. Filtered textures, liquid polygonal worlds and atmospheric light made GLQuake, Tomb Raider and later Unreal look like messages from the future. With the slim Glide interface 3dfx won the developers, with overwhelming performance the players. Within a very short time, the company dominated the market for 3D accelerators and brought arcade graphics to domestic PCs.
But the pioneer of speed himself became too slow. Nvidia released new chips in short cycles and consistently improved them. 3dfx planned major technological leaps but always delivered later. 32-bit color depth, consistent AGP support, DDR memory, and hardware transform and lighting came earlier in the competition. Voodoo 4 and Voodoo 5 were delayed, while GeForce set the beat long ago.
The acquisition of the card manufacturer STB was intended to open 3dfx to the important OEM market, but it did the opposite. The company has become a competitor of its previous partners. Diamond, Creative and other manufacturers switched to competition, while the acquired factory in Mexico had to compete against the cheaper Asian production. At the same time, Microsoft’s Direct3D increasingly displaced the proprietary Glide interface. Failed business, litigation, high losses and the expensive acquisition of GigaPixel exacerbated the crisis.
The next Rampage architecture, together with the Sage geometry processor and the planned Spectre maps, should enable the return to the top. Initial prototypes existed and parts of the technology were already working. However, the project never reached serial maturity and was no longer on the market. On 15 March In December 2000, the Board recommended the sale of the main assets and patents to Nvidia.
The Voodoo Wizard ended, but his influence lives on in modern graphics processors and in the memories of an entire generation of players. Whether Rampage 3dfx would have actually saved can no longer be proven today. However, given the working prototypes and their enormous potential, it remains a fascinating thought.
If the developers had only had half a year more, the world would be different today.
