Valve Anti-Cheat
Valve Anti-Cheat (VAC) is an anti-cheat software product developed by Valve as a component of the Steam platform, first released with ''Counter-Strike'' in 2002. When the software detects a cheat on a player's system, it will ban them in the future, possibly days or weeks after the original detection. It may kick players from the game if it detects errors in their system's memory or hardware. No information such as date of detection or type of cheat detected is disclosed to the player. After the player is notified, access to online "VAC protected" servers of the game the player cheated in is permanently revoked and additional restrictions are applied to the player's Steam account. During one week of November 2006, the system detected over 10,000 cheating attempts. During the month of December 2018 over 600,000 accounts were banned. History In 2001, Even Balance Inc., the developers of the anti-cheat software PunkBuster designed for ''Counter-Strike'' and ''Half-Life'' mods, st ...

Valve Corporation
Valve Corporation is an American video game developer, video game publisher, publisher, and digital distribution company headquartered in Bellevue, Washington. It is the developer of the software distribution platform Steam (service), Steam and the franchises ''Half-Life (series), Half-Life'', ''Counter-Strike'', ''Portal (series), Portal'', ''Day of Defeat'', ''Team Fortress'', ''Left 4 Dead (series), Left 4 Dead'' and ''Dota''. Valve was founded in 1996 by former Microsoft employees Gabe Newell and Mike Harrington. Their debut game, the first-person shooter (FPS) ''Half-Life (video game), Half-Life'' (1998), was a critical and commercial success; with its realism, scripted sequences and seamless narrative, it had a lasting influence on the FPS genre. Harrington left in 2000. In 2003, Valve launched Steam, followed by ''Half-Life 2'' in 2004. With advanced Physics engine, physics systems and an increased focus on story and characters, ''Half-Life 2'' received critical acclaim ...

Left 4 Dead 2
''Left 4 Dead 2'' is a 2009 first-person shooter game developed and published by Valve. The sequel to Turtle Rock Studios's ''Left 4 Dead'' (2008) and the second game in the ''Left 4 Dead'' series, it was released for Microsoft Windows and Xbox 360 in November 2009, Mac OS X in October 2010, and Linux in July 2013. ''Left 4 Dead 2'' builds upon cooperatively focused gameplay and Valve's proprietary Source engine, the same game engine used in the original ''Left 4 Dead''. Set during the aftermath of an apocalyptic pandemic, the game focuses on four new Survivors, fighting against hordes of zombies known as the Infected, who develop severe psychosis and act extremely aggressive. The Survivors must fight their way through five campaigns, interspersed with safe houses that act as checkpoints, with the goal of escape at each campaign's finale. The gameplay is procedurally altered by the " AI Director 2.0", which monitors the players' performance and adjusts the scenario to provid ...

Unreal Engine
Unreal Engine (UE) is a 3D computer graphics game engine developed by Epic Games, first showcased in the 1998 first-person shooter game ''Unreal''. Initially developed for PC first-person shooters, it has since been used in a variety of genres of games and has seen adoption by other industries, most notably the film and television industry. Unreal Engine is written in C++ and features a high degree of portability, supporting a wide range of desktop, mobile, console, and virtual reality platforms. The latest generation, Unreal Engine 5, was launched in April 2022. Its source code is available on GitHub after registering an account, and commercial use is granted based on a royalty model. Epic waives their royalties margin for games until developers have earned in revenue and the fee is waived if developers publish on the Epic Games Store. Epic has included features from acquired companies like Quixel in the engine, which is seen as helped by ''Fortnite'''s revenue. Histo ...

GoldSrc
GoldSrc ( ) is a proprietary game engine developed by Valve. At its core, GoldSrc is a heavily modified version of id Software's ''Quake'' engine. It originally made its debut in 1998 with ''Half-Life'', and would power future games developed by or with oversight from Valve, including ''Half-Life'' expansions, ''Day of Defeat'', and multiple games in the ''Counter-Strike'' series. GoldSrc was succeeded by the Source engine with the releases of '' Half-Life: Source'', ''Half-Life 2'', and '' Counter-Strike: Source'' in 2004. However, Valve continues to support the engine with periodic updates. Development The basis of GoldSrc is the engine used in the video game '' Quake'', albeit with heavy modification by Valve. While the engine served as the basis for GoldSrc, Gabe Newell has stated that a majority of the code used in the engine was created by Valve themselves. GoldSrc's artificial intelligence systems, for example, were essentially made from scratch. The engine also reuses ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Source (game Engine)
Source is a 3D game engine developed by Valve. It debuted as the successor to GoldSrc in 2004 with the release of '' Counter-Strike: Source'' and ''Half-Life 2''. Updates to Source were released in incremental versions, with the engine being succeeded by Source 2 by the late 2010s. History Source distantly originates from the GoldSrc engine, itself a heavily modified version of John Carmack's Quake engine with some code from the Quake II engine. Carmack commented on his blog in 2004 that "there are still bits of early ''Quake'' code in ''Half-Life 2''". Valve employee Erik Johnson explained the engine's nomenclature on the Valve Developer Community: Source was developed part-by-part from this fork onwards, slowly replacing GoldSrc in Valve's internal projects and, in part, explaining the reasons behind its unusually modular nature. Valve's development of Source since has been a mixture of licensed middleware and in-house-developed code. Among others, Source uses Bink Video fo ...

Process (computing)
In computing, a process is the instance of a computer program that is being executed by one or many threads. There are many different process models, some of which are light weight, but almost all processes (even entire virtual machines) are rooted in an operating system (OS) process which comprises the program code, assigned system resources, physical and logical access permissions, and data structures to initiate, control and coordinate execution activity. Depending on the OS, a process may be made up of multiple threads of execution that execute instructions concurrently. While a computer program is a passive collection of instructions typically stored in a file on disk, a process is the execution of those instructions after being loaded from the disk into memory. Several processes may be associated with the same program; for example, opening up several instances of the same program often results in more than one process being executed. Multitasking is a method to allow ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Computer Memory
In computing, memory is a device or system that is used to store information for immediate use in a computer or related computer hardware and digital electronic devices. The term ''memory'' is often synonymous with the term ''primary storage'' or '' main memory''. An archaic synonym for memory is store. Computer memory operates at a high speed compared to storage that is slower but less expensive and higher in capacity. Besides storing opened programs, computer memory serves as disk cache and write buffer to improve both reading and writing performance. Operating systems borrow RAM capacity for caching so long as not needed by running software. If needed, contents of the computer memory can be transferred to storage; a common way of doing this is through a memory management technique called ''virtual memory''. Modern memory is implemented as semiconductor memory, where data is stored within memory cells built from MOS transistors and other components on an integrated c ...

Heuristic
A heuristic (; ), or heuristic technique, is any approach to problem solving or self-discovery that employs a practical method that is not guaranteed to be optimal, perfect, or rational, but is nevertheless sufficient for reaching an immediate, short-term goal or approximation. Where finding an optimal solution is impossible or impractical, heuristic methods can be used to speed up the process of finding a satisfactory solution. Heuristics can be mental shortcuts that ease the cognitive load of making a decision. Examples that employ heuristics include using trial and error, a rule of thumb or an educated guess. Heuristics are the strategies derived from previous experiences with similar problems. These strategies depend on using readily accessible, though loosely applicable, information to control problem solving in human beings, machines and abstract issues. When an individual applies a heuristic in practice, it generally performs as expected. However it can alternatively cre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Kernel (operating System)
The kernel is a computer program at the core of a computer's operating system and generally has complete control over everything in the system. It is the portion of the operating system code that is always resident in memory and facilitates interactions between hardware and software components. A full kernel controls all hardware resources (e.g. I/O, memory, cryptography) via device drivers, arbitrates conflicts between processes concerning such resources, and optimizes the utilization of common resources e.g. CPU & cache usage, file systems, and network sockets. On most systems, the kernel is one of the first programs loaded on startup (after the bootloader). It handles the rest of startup as well as memory, peripherals, and input/output (I/O) requests from software, translating them into data-processing instructions for the central processing unit. The critical code of the kernel is usually loaded into a separate area of memory, which is protected from access by application ...

Reddit
Reddit (; stylized in all lowercase as reddit) is an American social news aggregation, content rating, and discussion website. Registered users (commonly referred to as "Redditors") submit content to the site such as links, text posts, images, and videos, which are then voted up or down by other members. Posts are organized by subject into user-created boards called "communities" or "subreddits". Submissions with more upvotes appear towards the top of their subreddit and, if they receive enough upvotes, ultimately on the site's front page. Reddit administrators moderate the communities. Moderation is also conducted by community-specific moderators, who are not Reddit employees. As of March 2022, Reddit ranks as the 9th- most-visited website in the world and 6th most-visited website in the U.S., according to Semrush. About 42–49.3% of its user base comes from the United States, followed by the United Kingdom at 7.9–8.2% and Canada at 5.2–7.8%. Twenty-two percent of U.S. ...
