Apache HTTP Server
The Apache HTTP Server ( ) is a free and open-source cross-platform web server software, released under the terms of Apache License 2.0. Apache is developed and maintained by an open community of developers under the auspices of the Apache Software Foundation. The vast majority of Apache HTTP Server instances run on a Linux distribution, but current versions also run on Microsoft Windows, OpenVMS, and a wide variety of Unix-like systems. Past versions also ran on NetWare, OS/2 and other operating systems, including ports to mainframes. Originally based on the NCSA HTTPd server, development of Apache began in early 1995 after work on the NCSA code stalled. Apache played a key role in the initial growth of the World Wide Web, quickly overtaking NCSA HTTPd as the dominant HTTP server. In 2009, it became the first web server software to serve more than 100 million websites. , Netcraft estimated that Apache served 23.04% of the million busiest websites, while Nginx served 22. ...

Modchip
A modchip (short for modification chip) is a small electronic device used to alter or disable artificial restrictions of computers or entertainment devices. Modchips are mainly used in video game consoles, but also in some DVD or Blu-ray players. They introduce various modifications to its host system's function, including the circumvention of region coding, digital rights management, and copy protection checks for the purpose of using media intended for other markets, copied media, or unlicensed third-party ( homebrew) software. Function and construction Modchips operate by replacing or overriding a system's protection hardware or software. They achieve this by either exploiting existing interfaces in an unintended or undocumented manner, or by actively manipulating the system's internal communication, sometimes to the point of re-routing it to substitute parts provided by the modchip. Most modchips consist of one or more integrated circuits (microcontrollers, FPGAs, or CPLDs ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
MOD And TOD
MOD and TOD are recording formats for use in digital tapeless camcorders. The formats are comparable to XDCAM EX, HDV and AVCHD. Overview MOD and TOD are informal names of tapeless video formats used by JVC (MOD and TOD), Panasonic (MOD only) and Canon (MOD only) in some models of digital camcorders. Format names correspond to extensions of video files. Neither JVC nor Panasonic, who pioneered the format, explained the meaning of the file extensions, and the formats were never given an official name. Some think that TOD stands for "Transport stream on disk". MOD is used exclusively for standard definition video files, while TOD is used for high definition files. The first camcorders that used MOD format appeared in 2003. JVC introduced the Everio GZ-MG30, which recorded directly to an internal hard disk drive. Panasonic unveiled the SDR-S100, which recorded to SD cards. The encoding scheme, data rate, frame rate and frame size closely matched parameters of DVD-video. In January ...

Modular Exponentiation
Modular exponentiation is exponentiation performed over a modulus. It is useful in computer science, especially in the field of public-key cryptography, where it is used in both Diffie-Hellman Key Exchange and RSA public/private keys. Modular exponentiation is the remainder when an integer (the base) is raised to the power (the exponent), and divided by a positive integer (the modulus); that is, . From the definition of division, it follows that . For example, given , and , dividing by leaves a remainder of . Modular exponentiation can be performed with a ''negative'' exponent by finding the modular multiplicative inverse of modulo using the extended Euclidean algorithm. That is: :, where and . Modular exponentiation is efficient to compute, even for very large integers. On the other hand, computing the modular discrete logarithm – that is, finding the exponent when given , , and – is believed to be difficult. This one-way function behavior makes modular ...

Modulo Operation
In computing, the modulo operation returns the remainder or signed remainder of a division, after one number is divided by another (called the '' modulus'' of the operation). Given two positive numbers and , modulo (often abbreviated as ) is the remainder of the Euclidean division of by , where is the dividend and is the divisor. For example, the expression "5 mod 2" would evaluate to 1, because 5 divided by 2 has a quotient of 2 and a remainder of 1, while "9 mod 3" would evaluate to 0, because 9 divided by 3 has a quotient of 3 and a remainder of 0; there is nothing to subtract from 9 after multiplying 3 times 3. Although typically performed with and both being integers, many computing systems now allow other types of numeric operands. The range of values for an integer modulo operation of is 0 to inclusive ( mod 1 is always 0; is undefined, possibly resulting in a division by zero error in some programming languages).

Modular Arithmetic
In mathematics, modular arithmetic is a system of arithmetic for integers, where numbers "wrap around" when reaching a certain value, called the modulus. The modern approach to modular arithmetic was developed by Carl Friedrich Gauss in his book ''Disquisitiones Arithmeticae'', published in 1801. A familiar use of modular arithmetic is in the 12-hour clock, in which the day is divided into two 12-hour periods. If the time is 7:00 now, then 8 hours later it will be 3:00. Simple addition would result in , but clocks "wrap around" every 12 hours. Because the hour number starts over at zero when it reaches 12, this is arithmetic ''modulo'' 12. In terms of the definition below, 15 is ''congruent'' to 3 modulo 12, so "15:00" on a 24-hour clock is displayed "3:00" on a 12-hour clock. Congruence Given an integer , called a modulus, two integers and are said to be congruent modulo , if is a divisor of their difference (that is, if there is an integer such that ).

Modulo (mathematics)
In mathematics, the term ''modulo'' ("with respect to a modulus of", the Latin ablative of '' modulus'' which itself means "a small measure") is often used to assert that two distinct mathematical objects can be regarded as equivalent—if their difference is accounted for by an additional factor. It was initially introduced into mathematics in the context of modular arithmetic by Carl Friedrich Gauss in 1801. Since then, the term has gained many meanings—some exact and some imprecise (such as equating "modulo" with "except for"). For the most part, the term often occurs in statements of the form: :''A'' is the same as ''B'' modulo ''C'' which means :''A'' and ''B'' are the same—except for differences accounted for or explained by ''C''. History ''Modulo'' is a mathematical jargon that was introduced into mathematics in the book ''Disquisitiones Arithmeticae'' by Carl Friedrich Gauss in 1801. Given the integers ''a'', ''b'' and ''n'', the expression "''a'' ≡ ''b'' (mod ' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mod N Cryptanalysis
In cryptography, mod ''n'' cryptanalysis is an attack applicable to block and stream ciphers. It is a form of partitioning cryptanalysis that exploits unevenness in how the cipher operates over equivalence classes (congruence classes) modulo ''n''. The method was first suggested in 1999 by John Kelsey, Bruce Schneier, and David Wagner and applied to RC5P (a variant of RC5) and M6 (a family of block ciphers used in the FireWire standard). These attacks used the properties of binary addition and bit rotation modulo a Fermat prime. Mod 3 analysis of RC5P For RC5P, analysis was conducted modulo 3. It was observed that the operations in the cipher (rotation and addition, both on 32-bit words) were somewhat biased over congruence classes mod 3. To illustrate the approach, consider left rotation by a single bit: : X \lll 1=\left\{\begin{matrix} 2X, & \mbox{if } X < 2^{31} \\ 2X + 1 - 2^{32}, & \mbox{if } X \geq 2^{31}\end{matrix}\right. Then, because : |
Video Game Modding
Video game modding (short for "modification") is the process of alteration by players or fans of one or more aspects of a video game, such as how it looks or behaves, and is a sub-discipline of general modding. Mods may range from small changes and tweaks to complete overhauls, and can extend the replay value and interest of the game. Modding a game can also be understood as the act of seeking and installing mods to the player's game, but the act of tweaking pre-existing settings and preferences is not truly modding. Mods have arguably become an increasingly important factor in the commercial success of some games, as they add depth to the original work, and can be both fun for players playing the mods and as means of self-expression for mod developers. People can become fans of specific mods, in addition to fans of the game they are for, such as requesting features and alterations for these mods. In cases where mods are very popular, players might have to clarify that they are r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Modula-2
Modula-2 is a structured, procedural programming language developed between 1977 and 1985/8 by Niklaus Wirth at ETH Zurich. It was created as the language for the operating system and application software of the Lilith personal workstation. It was later used for programming outside the context of the Lilith. Wirth viewed Modula-2 as a successor to his earlier programming languages Pascal and Modula. The main concepts are: # The module as a compiling unit for separate compiling # The coroutine as the basic building block for concurrent processes # Types and procedures that allow access to machine-specific data The language design was influenced by the Mesa language and the Xerox Alto, both from Xerox PARC, that Wirth saw during his 1976 sabbatical year there. Page 4. The computer magazine ''Byte'' devoted the August 1984 issue to the language and its surrounding environment. Modula-2 was followed by Modula-3, and later by the Oberon series of languages.

MOD (file Format)
MOD is a computer file format used primarily to represent music, and was the first module file format. MOD files use the “.MOD” file extension, except on the Amiga which doesn't rely on filename extensions; instead, it reads a file's header to determine filetype. A MOD file contains a set of ''instruments'' in the form of samples, a number of ''patterns'' indicating how and when the samples are to be played, and a list of what patterns to play in what order. History The first version of the format was created by Karsten Obarski for use in the Ultimate Soundtracker, tracker software released for the Amiga computer in 1987. The format has since been supported by hundreds of playback programs and dozens of other trackers. The original version of the MOD format featured four channels of simultaneous audio playback, corresponding to the capabilities of the original Amiga chipset, and up to 15 instruments. Later variations of the format have extended this to up to 32 chann ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
