GNU i/ɡnuː/[2][3] is a Unix-like computer operating system developed by the GNU Project. It is composed wholly of free software. It is based on the GNU Hurd kernel and is intended to be a "complete Unix-compatible software system"[1][4][5] GNU is a recursive acronym for "GNU's Not Unix!",[1][6] chosen because GNU's design is Unix-like, but differs from Unix by being free software and containing no Unix code.[7] Development of GNU was initiated by Richard Stallman in 1983[1][8] and was the original focus of the Free Software Foundation (FSF), but no stable release of GNU yet exists as of January 2014[update].[1][9][10][11] However, non-GNU kernels, most famously the Linux kernel, can also be used with GNU software.[12][13][14] Stallman views GNU as a "technical means to a social end. History[edit] The plan for the GNU ("GNU's Not Unix!") The goal was to bring a wholly free software operating system into existence.

Préparer l'environnement nécessaire pour développer en Objective-C sous Windows NB: Ce blog est désormais transféré vers cette adresse. Objective-C est un langage de programmation orienté objet. Il est beaucoup utilisé sur Macintosh, notamment pour les API cocoa de Mac OS X et, depuis 2007, pour le développement d'applications iPhone. Toutefois, pour apprendre à développer en Objective-C, on est pas obligé de se procurer d'un Macintosh, en effet, il existe une implémentation libre du framework OpenStep (développé par Apple) appelée GNUstep, qui est, pour ainsi dire, multiplateforme et fonctionne, du coup, sous GNU/Linux et Microsoft Windows. Dans ce tutoriel, je vais vous guider à travers les étapes nécessaires pour que vous arriverez à compiler vos propres codes Objective-C sous Windows. Télécharger et installer l'environnement Rendez vous au site officiel du projet GNUstep, dans la partie Download, téléchargez l'environnement complet pour la compilation et l'exécution de GNUstep. L'environnement étant composé de 4 packages, comme montre la figure suivante : 2.

Structured Programming Background Since the invention by Von Neumann of the stored program computer, computer scientists have known that a tremendous power of computing equipment was the ability to alter its behavior, depending on the input data. Calculating machines had, for some time, been able to perform fixed arithmetic operations on data, but the potential of machines capable of making decisions opened up many new possibilities. Machines that could make decisions were capable of sorting records, tabulating and summarizing data, searching for information, and many more advanced operations that could not even be imagined at the time. In early programming languages, like Fortran (first invented in 1954) and various low level machine languages, the goto statement allowed the computer to deviate from the sequential execution of the program instructions. However, the increasingly complex code that resulted from goto statements became harder and harder to maintain. 1. Add flour. 2. Example: Washing Dishes 3.
Adobe's Flash Pro CC Exports to Dart and HTML5 At Google I/O today, Adobe announced their new Toolkit for Dart, a plugin for Flash Professional CC that allows developers to export their animations and games to Dart code and HTML5. "Adobe is delighted to announce the Toolkit for Dart, an extension that enables web designers and animators to publish their Flash content to Dart." said Tom Barclay, Sr. Product Manager at Adobe. With the Toolkit, developers, designers, and animators can create interactive, animated content inside of Flash Pro and publish to the Dart language and HTML5 APIs. Toolkit for Dart supports many of the core animation and drawing capabilities of Flash Pro, including bitmaps, shapes, movie clips, graphic symbols, classic tweens and motion guides, simple buttons, text fields, drop-shadow and glow filters, additive blend mode, single-shape masks, visible and cacheAsBitmap display options, and embedded audio. The Toolkit doesn't translate ActionScript to Dart.
Year 2000 problem The (French) sign reads "3 January 1900" instead of "3 January 2000" The Year 2000 problem (also known as the Y2K problem, the Millennium bug, the Y2K bug, or simply Y2K) was a problem for both digital (computer-related) and non-digital documentation and data storage situations which resulted from the practice of abbreviating a four-digit year to two digits. In 1997, The British Standards Institute (BSI) developed a standard, DISC PD2000-1,[1] which defines "Year 2000 Conformity requirements" as four rules: No valid date will cause any interruption in operations.Calculation of durations between, or the sequence of, pairs of dates will be correct whether any dates are in different centuries.In all interfaces and in all storage, the century must be unambiguous, either specified, or calculable by algorithmYear 2000 must be recognized as a leap year It identifies two problems that may exist in many computer programs.

Android++ : une extension pour d velopper des applications Android dans Visual Studio Le développeur Justin Webb présente Android++, une extension Visual Studio pour créer et déboguer des applications natives Android. Le projet est actuellement en bêta fermée. Webb, qui est à la tête des programmeurs Android de la société Natural Motion (une compagnie basée en Angleterre qui développe des jeux vidéos), explique que, contrairement à d'autres solutions, Android++ est destiné à la majorité des appareils ; il n'y a pas de limitation matérielle ou fournisseur et encore moins de vérification de licence. Le projet a été principalement conçu pour les applications C/C++ créées avec la boîte à outils Android NDK ; l'extension a des fonctionnalités supplémentaires telles que la compilation des sources Java intégrée et le déploiement personnalisable. Pour Webb, l'une des faiblesses majeures de l'IDE est un manque d'options natives pour le débogage. Télécharger Android++ (Windows) Source : site officiel Et vous ?

COBOL COBOL (/ˈkoʊbɒl/, an acronym for common business-oriented language) is a compiled English-like computer programming language designed for business use. It is imperative, procedural and, since 2002, object-oriented. COBOL is primarily used in business, finance, and administrative systems for companies and governments. In 1997, Gartner Group estimated that there were a total of 200 billion lines of COBOL in existence which ran 80% of all business programs.[2] It was designed in 1959 by the Conference on Data Systems Languages (CODASYL) and was largely based on previous programming language design work by Grace Hopper, commonly referred to as "the (grand)mother of COBOL".[3][4][5] It was created as part of a US Department of Defense effort to create a portable programming language for data processing. COBOL has an English-like syntax which was designed to be self-documenting and highly readable. History and specification[edit] Background[edit] COBOL 60[edit] The cover of the COBOL 60 report.
ROOMn 2014 – Genymobile sécurise le développement sur Android La société fondée par Arnaud Dupuis, Angélique Zettor et Cédric Ravalec s’est focalisée sur la sécurisation de l’environnement Android sous toutes ses formes. « Notre mission est d’accompagner les grands comptes dans ce marasme et cet océan de nouveautés que constituent la mobilité et les objets connectés, explique Arnaud Dupuis, CEO de Genymobile. L’intérêt d’Android est qu’en tant qu’OS open-source, on peut en faire ce que l’on veut. (...) Nous sommes capable de réaliser des développements de très bas niveau jusqu’au noyau Linux. Outre son activité de services, Genymobile a développé une solution de déploiements de terminaux, un master sécurisé et un émulateur (Genymotion), toujours dans l’environnement Android.
Unity (game engine) Unity is a cross-platform[2] game engine with a built-in IDE developed by Unity Technologies. It is used to develop video games for web plugins, desktop platforms, consoles and mobile devices. It grew from an OS X supported game development tool in 2005 to a multi-platform game engine.[3] Gone Home is a 2013 video game built with the Unity engine The graphics engine uses Direct3D (Windows, Xbox 360), OpenGL (Mac, Windows, Linux), OpenGL ES (Android, iOS), and proprietary APIs (consoles). Unity also includes the Unity Asset Server - a version control solution for the developer's game assets and scripts. Unity supports deployment to multiple platforms. Upcoming platforms include PlayStation 4 and Xbox One. The first version of Unity was launched at Apple’s Worldwide Developers Conference in 2005. Unity 4 was announced on June 18, 2012 and includes several new additions to the technology in the initial Unity 4.0 release. New features include DirectX 11 support and Mecanim animation.
