Up and Down the Ladder of Abstraction In real life, you would never use a ladder that only let you go up. Likewise, when creating abstractions, stepping down is as important as stepping up. Here, we take the abstraction from the previous section, and overlay a concrete representation on top of it. That is, we draw the trajectory that represents all time, but we also draw the car at some particular time. How do we select which particular time to show? This is a general and powerful technique. Try cranking up the turning rate to 8° or so, and then inspecting the car's behavior as it makes its first two turns. In this case, it's fairly easy to look at the trajectory and imagine the car moving along.

Pi-calcul Un article de Wikipédia, l'encyclopédie libre. Le Pi-calcul (ou π-calcul) est un langage de programmation théorique inventé par Robin Milner. Ce langage occupe dans le domaine de l'informatique parallèle et distribuée un rôle similaire à celui du λ-calcul dans l'informatique classique. La problématique[modifier | modifier le code] En tant que langage de programmation théorique (ou langage formel), le π-calcul ne vise pas à permettre de construire des programmes exécutables. Afin de construire un programme exécutable, il est nécessaire de passer par un langage de programmation concret dérivé (ou inspiré) du π-calcul, tel que JoCaml, Acute ou Nomadic Pict. Définition informelle[modifier | modifier le code] Les entités du π-calcul[modifier | modifier le code] Plutôt que des données explicites, les programmes écrits en π-calcul manipulent des noms, notés typiquement a, b, c… x, y, z. Les constructions du π-calcul[modifier | modifier le code] Processus terminé[modifier | modifier le code] . . .

List of programming languages The aim of this list of programming languages is to include all notable programming languages in existence, both those in current use and historical ones, in alphabetical order, except for dialects of BASIC and esoteric programming languages. Note: Dialects of BASIC have been moved to the separate List of BASIC dialects. Note: This page does not list esoteric programming languages.

Lost Programming Skills | PCWorld August 05, 2011, 8:30 AM — Back to basicsThis still comes back to the basic guideline: 'learn your fundamentals.' You don't need to learn them all (designing CPU instruction sets??), but you do need to know the primary layers you interact with. A web programmer generally doesn't need to be aware of the machine code generated by his application, but should be knowledgeable in networking (layer 3 and up), caching, databases, and so on. Hacker News user ominous_prime | What's your take? Today's coders may know how to whip up a PHP script or a Drupal extension, create a mobile app for both the iPhone and Android, and run DOOM on their car's GPS (which has been done, it turns out). Some of these skills aren't likely to be needed again, any more than most of us need to know how to ride a horse or (sigh) drive a manual-transmission vehicle.

Download Official Kali Images | Kali Linux Official Documentation IMPORTANT! Never download Kali Linux images from anywhere other than the official sources. Always be sure to verify the SHA1 checksums of the file you’ve downloaded against our official values. ISO Files for Intel-based PCs In order to run Kali “Live” from a USB drive on standard Windows and Macintosh PCs, you’ll need a Kali Linux bootable ISO image, in either 32-bit or 64-bit formats. If you’re not sure of the architecture of the system you want to run Kali Linux on, on Linux or OS X, you can run the command at the command line. The images are available both as directly downloaded “.iso” files or via torrent files. Official Kali ISOs for Intel-based PCs Building your own Kali Linux ISO, standard or customized, is a very simple process. VMware Images If you want to run Kali Linux as a “guest” under VMware, Kali is available as a pre-built VMware virtual machine with VMware Tools already installed.

OCaml Un article de Wikipédia, l'encyclopédie libre. OCaml est le successeur de Caml Light, auquel il a ajouté entre autres une couche de programmation objet. L'acronyme CAML provient de Categorical Abstract Machine Language, un modèle de machine abstraite qui n'est cependant plus utilisé dans les versions récentes de OCaml. Principes[modifier | modifier le code] Il intègre ces différents concepts dans un système de types hérité de ML, caractérisé par un typage statique, fort et inféré. Le système de types permet une manipulation aisée de structures de données complexes : on peut aisément représenter des types algébriques, c'est-à-dire des types hiérarchisés et potentiellement récursifs (listes, arbres…), et les manipuler aisément à l'aide du filtrage par motif. Histoire[modifier | modifier le code] En 1995, Xavier Leroy publie une version de Caml nommée Caml Special Light, qui introduit un compilateur de code natif, et un système de modules inspiré des modules de Standard ML.

The 2008 PC Builder's Bible Getting your hands dirty and building your own system is what separates PC gamers from their console brethren, and it just so happens to be one of the most exciting parts of our hobby. Unfortunately, it’s also a pretty daunting process for anyone who hasn’t assembled his own rig from scratch. Thankfully, this guide not only gives you all you need to know about every component that goes in your gaming PC, but also thoroughly walks you through the entire building process with detailed instructions and helpful photographs. We’ve always written the PC Builder’s Bible not only as a guide for new system builders who want more versatility from their computer, but also for hardcore enthusiasts who have to be on the cutting edge of technological innovation. Above: Building your own PC isn’t as difficult as it seems. Wrap your head around the various motherboard chipsets that create the backbone of your gaming PC. CPUS Dual core or quad core? RAM DDR2 or DDR3? - Choose the RAM that’s right for you
