L’atelier Hypermedia enseigne la conception d’images, de programmes et d’animations informatiques. l’accènt est mis sur la construction de dispositifs singuliers et experimentaux, plutôt que sur la maîtrise de logiciels ou de procédés standardisés : les étudiants sont invités à construire leur propres outils, par le biais de langages simples ou complexes tels que BASIC, Logo, Robolab, Lego Mindstorms, C, Lingo, Cocoa, Javascript, Actionscript, Processing, MySQL/PHP, ou Java. L’atelier Hypermedia ne voit pas de contradiction dans l’idée d’un travail plastique de la programmation. L’atelier ne fait pas de distinction entre low-tech et high-tech. les supports de création peuvent aller de Macintosh à Windows, en passant par Gameboy, Atari, Palm, PocketPC, Apple ][ ... L’atelier s’oppose à toute notion de sous-traitance, et préfére travailler avec les autres ateliers dans une logique d’interfaçage.

ditaa is a small command-line utility written in Java, that can convert diagrams drawn using ascii art ('drawings' that contain characters that resemble lines like | / - ), into proper bitmap graphics.

Threading

We’re quite familiar with the idea of writing a program that follows a specific sequence of steps as outlined in, say, a main() function. A Thread is also a series of steps with a beginning, a middle, and an end. A thread’s sequence, however, can run independently of the main program. In fact, we can launch any number of threads at one time and they will all run concurrently. Visit the Java site for a more involved explanation.

This is incredibly useful when it comes to data mining, as we can have separate threads retrieving different pieces of information from the network. If one gets stuck or has an error, the entire program won’t grind to a halt, since the error only stops that individual thread. To create independent, asynchronous threads, we simply extend the Thread class.

Comparing Python and Java

A programmer can be significantly more productive in Python than in Java.

How much more productive? The most widely accepted estimate is 5-10 times. On the basis of my own personal experience with the two languages, I agree with this estimate.

Need to distribute documentation, create an eBook, or just archive your favorite blog posts? EPUB is an open specification for digital books based on familiar technologies like XML, CSS, and XHTML, and EPUB files can be read on portable e-ink devices, mobile phones, and desktop computers. This tutorial explains the EPUB format in detail, demonstrates EPUB validation using Java technology, and moves step-by-step through automating EPUB creation using DocBook and Python.

Processing for the Web is a proposed Mozilla-sponsored initiative to create a complete and robust port of the Java-based Processing language and environment (popular for art, design, and visualization applications) to the open web, using standard technologies such as JavaScript, Canvas, etc.
