Mahjong Solitaire
Mahjong solitaire (also known as Shanghai solitaire, electronic or computerized mahjong, solitaire mahjong or simply mahjong) is a single-player matching game that uses a set of mahjong tiles rather than cards. It is more commonly played on a computer than as a physical tabletop game. Its name comes from the four-player game mahjong, but it is played entirely differently. Play The 144 tiles are arranged in a four-layer pattern with their faces upwards. A tile is said to be open or exposed if it can be moved either left or right without disturbing other tiles. The goal is to match open pairs of identical tiles and remove them from the board, exposing the tiles under them for play. The game is won when all pairs of tiles have been removed from the board, and lost if the remaining tiles contain no exposed pairs. Mathematical analysis Playing Mahjong solitaire optimally in the sense to maximize the probability of removing all tiles is PSPACE-complete, and the game is NP-comple ...

Gnome Mahjong
A gnome is a mythological creature and diminutive spirit in Renaissance magic and alchemy, first introduced by Paracelsus in the 16th century and later adopted by more recent authors including those of modern fantasy literature. Its characteristics have been reinterpreted to suit the needs of various story tellers, but it is typically said to be a small humanoid that lives underground. Diminutive statues of gnomes introduced as lawn ornaments during the 19th century grew in popularity during the 20th century and came to be known as garden gnomes. History Origins The word comes from Renaissance Latin ''gnomus'', which first appears in ''A Book on Nymphs, Sylphs, Pygmies, and Salamanders, and on the Other Spirits'' by Paracelsus, published posthumously in Nysa, Poland, Nysa in 1566 (and again in the Johannes Huser edition of 1589–1591 from an autograph by Paracelsus). The term may be an original invention of Paracelsus, possibly deriving the term from Latin ''gēnomos'' (its ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Control Data Corporation
Control Data Corporation (CDC) was a mainframe and supercomputer firm. CDC was one of the nine major United States computer companies through most of the 1960s; the others were IBM, Burroughs Corporation, DEC, NCR, General Electric, Honeywell, RCA, and UNIVAC. CDC was well-known and highly regarded throughout the industry at the time. For most of the 1960s, Seymour Cray worked at CDC and developed a series of machines that were the fastest computers in the world by far, until Cray left the company to found Cray Research (CRI) in the 1970s. After several years of losses in the early 1980s, in 1988 CDC started to leave the computer manufacturing business and sell the related parts of the company, a process that was completed in 1992 with the creation of Control Data Systems, Inc. The remaining businesses of CDC currently operate as Ceridian. Background and origins: World War II–1957 During World War II the U.S. Navy had built up a classified team of engineers to build codeb ...

Microsoft Entertainment Pack
''Microsoft Entertainment Pack'' , also known as ''Windows Entertainment Pack'' or simply ''WEP'' , is a collection of 16-bit casual computer games for Windows. There were four Entertainment Packs released between 1990 and 1992. These games were somewhat unusual for the time, in that they would not run under MS-DOS. In 1994, a compilation of the previous four ''Entertainment Packs'' were released called ''The Best of Microsoft Entertainment Pack''. A Game Boy Color version was released in 2000. Microsoft advertised Entertainment Packs for casual gaming on office computers. The boxes had slogans like "No more boring coffee breaks" and "Only a few minutes between meetings? Get in a quick game of Klotski". The marketing succeeded; ''Computer Gaming World'' in 1992 described the series as "the Gorillas of the Gaming Lite Jungle", with more than 500,000 copies sold. ''Minesweeper'' from pack 1 was later bundled with Windows 3.1, and FreeCell was included in Windows 95. ''WinChess ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trademark
A trademark (also written trade mark or trade-mark) is a type of intellectual property consisting of a recognizable sign, design, or expression that identifies products or services from a particular source and distinguishes them from others. The trademark owner can be an individual, business organization, or any legal entity. A trademark may be located on a package, a label, a voucher, or on the product itself. Trademarks used to identify services are sometimes called service marks. The first legislative act concerning trademarks was passed in 1266 under the reign of Henry III of England, requiring all bakers to use a distinctive mark for the bread they sold. The first modern trademark laws emerged in the late 19th century. In France, the first comprehensive trademark system in the world was passed into law in 1857. The Trade Marks Act 1938 of the United Kingdom changed the system, permitting registration based on "intent-to-use", creating an examination based process, an ...

Porting
In software engineering, porting is the process of adapting software for the purpose of achieving some form of execution in a computing environment that is different from the one that a given program (meant for such execution) was originally designed for (e.g., different CPU, operating system, or third party library). The term is also used when software/hardware is changed to make them usable in different environments. Software is ''portable'' when the cost of porting it to a new platform is significantly less than the cost of writing it from scratch. The lower the cost of porting software relative to its implementation cost, the more portable it is said to be. Etymology The term "port" is derived from the Latin '' portāre'', meaning "to carry". When code is not compatible with a particular operating system or architecture, the code must be "carried" to the new system. The term is not generally applied to the process of adapting software to run with less memory on the sam ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Apple IIgs
The Apple IIGS (styled as II), the fifth and most powerful of the Apple II family, is a 16-bit personal computer produced by Apple Computer. While featuring the Macintosh look and feel, and resolution and color similar to the Amiga and Atari ST, it remains compatible with earlier Apple II models. The "GS" in the name stands for "Graphics and Sound," referring to its enhanced multimedia hardware, especially its state-of-the-art audio. The microcomputer is a radical departure from any previous Apple II, with a 16-bit 65C816 microprocessor, direct access to megabytes of random-access memory (RAM), and bundled mouse. It is the first computer from Apple with a color graphical user interface (color was introduced on the Macintosh II six months later) and Apple Desktop Bus interface for keyboards, mice, and other input devices. It is the first personal computer with a wavetable synthesis chip, using technology from Ensoniq. The IIGS set forth a promising future and evolutionary advan ...
