Clayton Walnum
Clayton Walnum is a programmer who has written multiple books about programming in C#, DirectX and C++. Clayton Walnum started programming computers in 1982, when he traded an IBM Selectric typewriter to buy an Atari 400 computer with 16K of RAM. He was hired as a Technical Editor for Atari 8-bit computer magazine ANALOG Computing in 1985, eventually becoming Executive Editor before leaving in 1989, the year the publication folded. He authored a number of type-in games for ''ANALOG'', including ''Dragonlord'' (1985) and ''Moonlord'' (1986), mostly written in Atari BASIC. Walnum has since acquired a degree in computer science Computer science is the study of computation, automation, and information. Computer science spans theoretical disciplines (such as algorithms, theory of computation, information theory, and automation) to practical disciplines (includin ..., and written over 30 books (translated into many languages).

Programming Language
A programming language is a system of notation for writing computer programs. Most programming languages are text-based formal languages, but they may also be graphical. They are a kind of computer language. The description of a programming language is usually split into the two components of syntax (form) and semantics (meaning), which are usually defined by a formal language. Some languages are defined by a specification document (for example, the C programming language is specified by an ISO Standard) while other languages (such as Perl) have a dominant implementation that is treated as a reference. Some languages have both, with the basic language defined by a standard and extensions taken from the dominant implementation being common. Programming language theory is the subfield of computer science that studies the design, implementation, analysis, characterization, and classification of programming languages. Definitions There are many considerations when defining ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
C Sharp (programming Language)
C# (pronounced ) is a general-purpose, high-level multi-paradigm programming language. C# encompasses static typing, strong typing, lexically scoped, imperative, declarative, functional, generic, object-oriented ( class-based), and component-oriented programming disciplines. The C# programming language was designed by Anders Hejlsberg from Microsoft in 2000 and was later approved as an international standard by Ecma (ECMA-334) in 2002 and ISO/ IEC (ISO/IEC 23270) in 2003. Microsoft introduced C# along with .NET Framework and Visual Studio, both of which were closed-source. At the time, Microsoft had no open-source products. Four years later, in 2004, a free and open-source project called Mono began, providing a cross-platform compiler and runtime environment for the C# programming language. A decade later, Microsoft released Visual Studio Code (code editor), Roslyn (compiler), and the unified .NET platform (software framework), all of which support C# and are ...

DirectX
Microsoft DirectX is a collection of application programming interfaces (APIs) for handling tasks related to multimedia, especially game programming and video, on Microsoft platforms. Originally, the names of these APIs all began with "Direct", such as Direct3D, DirectDraw, DirectMusic, DirectPlay, DirectSound, and so forth. The name ''DirectX'' was coined as a shorthand term for all of these APIs (the ''X'' standing in for the particular API names) and soon became the name of the collection. When Microsoft later set out to develop a gaming console, the ''X'' was used as the basis of the name Xbox to indicate that the console was based on DirectX technology. The ''X'' initial has been carried forward in the naming of APIs designed for the Xbox such as XInput and the Cross-platform Audio Creation Tool (XACT), while the DirectX pattern has been continued for Windows APIs such as Direct2D and DirectWrite. Direct3D (the 3D graphics API within DirectX) is widely used in the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
IBM Selectric Typewriter
The IBM Selectric typewriter was a highly successful line of electric typewriters introduced by IBM on 31 July 1961. Instead of the "basket" of individual typebars that swung up to strike the ribbon and page in a typical typewriter of the period, the Selectric had an "element" (frequently called a "typeball", or less formally, a "golf ball") that rotated and pivoted to the correct position before striking the paper. The element could be easily interchanged to use different fonts within the same document typed on the same typewriter, resurrecting a capability which had been pioneered by typewriters such as the Hammond and Blickensderfer in the late 19th century. The Selectric also replaced the traditional typewriter's horizontally-moving carriage with a roller ( platen) that turned to advance the paper vertically, while the typeball and ribbon mechanism moved horizontally across the paper. The Selectric mechanism was notable for using internal mechanical binary coding and two me ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Atari 400
The Atari 8-bit family is a series of 8-bit home computers introduced by Atari, Inc. in 1979 as the Atari 400 and Atari 800. The series was successively upgraded to Atari 1200XL , Atari 600XL, Atari 800XL, Atari 65XE, Atari 130XE, Atari 800XE, and Atari XEGS, the last discontinued in 1992. They differ primarily in packaging, each based on the MOS Technology 6502 CPU at and the same custom coprocessor chips. As the first home computer architecture with coprocessors, it has graphics and sound more advanced than most contemporary machines. Video games were a major draw, and first-person space combat simulator ''Star Raiders'' is considered the platform's killer app. The plug-and-play peripherals use the Atari SIO serial bus, with one developer eventually also co-patenting USB. While using the same internal technology, the Atari 800 was sold as a high-end model, while the 400 was more affordable. The 400 has a pressure-sensitive, spillproof membrane keyboard and initially ship ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ANALOG Computing
''ANALOG Computing'' (an acronym for Atari Newsletter And Lots Of Games) was an American computer magazine devoted to the Atari 8-bit family of home computers. It was published from 1981 until 1989. In addition to reviews and tutorials, ''ANALOG'' printed multiple programs in each issue for users to type in. The magazine had a reputation for listings of machine language games–much smoother than those written in Atari BASIC—and which were uncommon in competing magazines. Such games were accompanied by the assembly language source code. ''ANALOG'' also sold commercial games, two books of type-in software, and access to a custom bulletin-board system. Originally the title as printed on the cover was ''A.N.A.L.O.G. 400/800 Magazine'', but by the eighth issue it changed to ''A.N.A.L.O.G. Computing''. Though the dots remained in the logo, it was simply referred to as ''ANALOG'' or ''ANALOG Computing'' inside the magazine. While the program listings were covered under the ...

Atari BASIC
Atari BASIC is an interpreter for the BASIC programming language that shipped with the Atari 8-bit family of 6502-based home computers. Unlike most American BASICs of the home computer era, Atari BASIC is not a derivative of Microsoft BASIC and differs in significant ways. It includes keywords for Atari-specific features and lacks support for string arrays, for example. The language was distributed as an 8 KB ROM cartridge for use with the 1979 Atari 400 and 800 computers. Starting with the 600XL and 800XL in 1983, BASIC is built into the system. Despite the Atari 8-bit computers running at a higher speed than most of its contemporaries, several technical decisions placed Atari BASIC near the bottom in performance benchmarks. The original authors addressed most of these issues in a series of improved versions: BASIC A+ (1981), BASIC XL (1983), and BASIC XE (1985). A host of third-party interpreters and compilers like Turbo-Basic XL also appeared. The complete, anno ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Computer Science
Computer science is the study of computation, automation, and information. Computer science spans theoretical disciplines (such as algorithms, theory of computation, information theory, and automation) to practical disciplines (including the design and implementation of hardware and software). Computer science is generally considered an area of academic research and distinct from computer programming. Algorithms and data structures are central to computer science. The theory of computation concerns abstract models of computation and general classes of problems that can be solved using them. The fields of cryptography and computer security involve studying the means for secure communication and for preventing security vulnerabilities. Computer graphics and computational geometry address the generation of images. Programming language theory considers different ways to describe computational processes, and database theory concerns the management of repositories ...

Computer Programmers
A computer programmer, sometimes referred to as a software developer, a software engineer, a programmer or a coder, is a person who creates computer programs — often for larger computer software. A programmer is someone who writes/creates computer software or applications by providing a specific programming language to the computer. Most programmers have extensive computing and coding experience in many varieties of programming languages and platforms, such as Structured Query Language (SQL), Perl, Extensible Markup Language (XML), PHP, HTML, C, C++ and Java. A programmer's most often-used computer language (e.g., Assembly, C, C++, C#, JavaScript, Lisp, Python, Java, etc.) may be prefixed to the aforementioned terms. Some who work with web programming languages may also prefix their titles with ''web''. Terminology There is no industry-wide standard terminology, so "programmer" and " software engineer" might refer to the same role at different companies. Most typica ...
