PC²
PC² is the Programming Contest Control System developed at California State University, Sacramento in support of Computer Programming Contest activities of the ACM, and in particular the ACM International Collegiate Programming Contest. It was used to conduct the ACM ICPC World Finals in 1990 and from 1994 through 2009. In 2010, the ACM ICPC World Finals switched to using Kattis, the KTH automated teaching tool; however, PC2 continues to be used for a large number of ICPC Regional Contests around the world. Computer programming contests and PC² Computer programming contest have rules and methods for judging submissions. The following describes in a general way a contest where PC2 is used. A computer programming contest is a competition where teams submit (computer program) solutions to judges. The teams are given a set of problems to solve in a limited amount of time (for example 8-13 problems in 5 hours). The judges then give pass/fail judgements to the submitted solutions. Tea ...

International Collegiate Programming Contest
The ICPC International Collegiate Programming Contest, known as the ICPC, is an annual multi-tiered competitive programming competition among the universities of the world. Directed by ICPC Executive Director and Baylor Professor Dr. William B. Poucher, the ICPC operates autonomous regional contests covering six continents culminating in a global World Finals every year. In 2018, ICPC participation included 52,709 students from 3,233 universities in 110 countries. The ICPC operates under the auspices of the ICPC Foundation and operates under agreements with host universities and non-profits, all in accordance with the ICPC Policies and Procedures. From 1977 until 2017 ICPC was held under the auspices of ACM and was referred to as ACM-ICPC. Mission The ICPC, the “International Collegiate Programming Contest”, is an extra-curricular, competitive programming sport for students at universities around the world. ICPC competitions provide gifted students opportunities to interact ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Principal Component Analysis
Principal component analysis (PCA) is a popular technique for analyzing large datasets containing a high number of dimensions/features per observation, increasing the interpretability of data while preserving the maximum amount of information, and enabling the visualization of multidimensional data. Formally, PCA is a statistical technique for reducing the dimensionality of a dataset. This is accomplished by linearly transforming the data into a new coordinate system where (most of) the variation in the data can be described with fewer dimensions than the initial data. Many studies use the first two principal components in order to plot the data in two dimensions and to visually identify clusters of closely related data points. Principal component analysis has applications in many fields such as population genetics, microbiome studies, and atmospheric science. The principal components of a collection of points in a real coordinate space are a sequence of p unit vectors, where the ...

MS-DOS
MS-DOS ( ; acronym for Microsoft Disk Operating System, also known as Microsoft DOS) is an operating system for x86-based personal computers mostly developed by Microsoft. Collectively, MS-DOS, its rebranding as IBM PC DOS, and a few operating systems attempting to be compatible with MS-DOS, are sometimes referred to as "DOS" (which is also the generic acronym for disk operating system). MS-DOS was the main operating system for IBM PC compatibles during the 1980s, from which point it was gradually superseded by operating systems offering a graphical user interface (GUI), in various generations of the graphical Microsoft Windows operating system. IBM licensed and re-released it in 1981 as PC DOS 1.0 for use in its PCs. Although MS-DOS and PC DOS were initially developed in parallel by Microsoft and IBM, the two products diverged after twelve years, in 1993, with recognizable differences in compatibility, syntax, and capabilities. Beginning in 1988 with DR-DOS, Co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Java (programming Language)
Java is a high-level, class-based, object-oriented programming language that is designed to have as few implementation dependencies as possible. It is a general-purpose programming language intended to let programmers ''write once, run anywhere'' ( WORA), meaning that compiled Java code can run on all platforms that support Java without the need to recompile. Java applications are typically compiled to bytecode that can run on any Java virtual machine (JVM) regardless of the underlying computer architecture. The syntax of Java is similar to C and C++, but has fewer low-level facilities than either of them. The Java runtime provides dynamic capabilities (such as reflection and runtime code modification) that are typically not available in traditional compiled languages. , Java was one of the most popular programming languages in use according to GitHub, particularly for client–server web applications, with a reported 9 million developers. Java was originally de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
IBM VisualAge
VisualAge is a family of computer integrated development environments from IBM, which supports multiple programming languages. VisualAge was first released in October 1993 and was discontinued April 30, 2007 and its web page removed in September 2011. VisualAge was also marketed as VisualAge Smalltalk, and in 2005, Instantiations, Inc. acquired the worldwide rights to this product. IBM has stated that XL C/C++ is the followup product to VisualAge. Early history VisualAge was created in the IBM development lab in Research Triangle Park, North Carolina, which was established in 1984 and had responsibility for application development tools. The EZ-VU dialog manager product, a personal computer derivative of the user interface elements of the ISPF 327x product was one of the first products in this family. The lab also had a group which was one of the early adopters of object-oriented programming technologies within IBM using an internally developed language called ClassC to develop ...

Visual Basic (classic)
The original Visual Basic (also referred to as Classic Visual Basic) is a third-generation event-driven programming language from Microsoft known for its Component Object Model (COM) programming model first released in 1991 and declared legacy during 2008. Microsoft intended Visual Basic to be relatively easy to learn and use. Visual Basic was derived from BASIC and enables the rapid application development (RAD) of graphical user interface (GUI) applications, access to databases using Data Access Objects, Remote Data Objects, or ActiveX Data Objects, and creation of ActiveX controls and objects. A programmer can create an application using the components provided by the Visual Basic program itself. Over time the community of programmers developed third-party components. Programs written in Visual Basic can also make use of the Windows API, which requires external functions declarations. The final release was version 6 in 1998. On April 8, 2008, Microsoft stopped s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kermit (protocol)
Kermit is a computer file transfer/management protocol and a set of communications software tools primarily used in the early years of personal computing in the 1980s. It provides a consistent approach to file transfer, terminal emulation, script programming, and character set conversion across many different computer hardware and operating system platforms. Technical The Kermit protocol supports text and binary file transfers on both full-duplex and half-duplex 8-bit and 7-bit serial connections in a system- and medium-independent fashion, and is implemented on hundreds of different computer and operating system platforms. On full-duplex connections, a sliding window protocol is used with selective retransmission which provides excellent performance and error recovery characteristics. On 7-bit connections, locking shifts provide efficient transfer of 8-bit data. When properly implemented, as in the Columbia University Kermit Software collection, its authors claim performance ...

Turbo Pascal
Turbo Pascal is a software development system that includes a compiler and an integrated development environment (IDE) for the Pascal programming language running on CP/M, CP/M-86, and DOS. It was originally developed by Anders Hejlsberg at Borland, and was notable for its extremely fast compilation. Turbo Pascal, and the later but similar Turbo C, made Borland a leader in PC-based development. For versions 6 and 7 (last), both a lower-priced Turbo Pascal and more expensive Borland Pascal were produced; Borland Pascal was more oriented toward professional software development, with more libraries and standard library source code. The name Borland Pascal is also used more generically for Borland's dialect of the Pascal programming language, significantly different from Standard Pascal. Borland has released three old versions of Turbo Pascal free of charge because of their historical interest: the original Turbo Pascal (now known as 1.0), and versions 3.02 and 5.5 for DOS. ...
