Open Source CMS

This great web site gives you the opportunity to test Content Management Systems (CMS) and Blogs open source software with a lot of installed end-user and administrator demos.

English (US)   DWR (Direct Web Remoting): Ajax for Java  -  Categories: Ajax  -  @ 02:18:54 pm
dwr

Extract from the technical introduction on DWR:
"DWR (Direct Web Remoting) is an open source Java library which helps developers wanting to write web sites that include Ajax technology. It allows code in a web browser to use Java functions running on a web server as if it was in the browser."

I have not yet tested this implementation of Ajax put I will test it ASAP. For more information about Ajax, read my previous note on this topic.

Ajax

Ajax means "Asynchronous JavaScript + XML". It's not a library but more an architecture, a new approach for web applications based on existing building blocks (XML, CSS, Javascript). The goal of Ajax is to have a more rich user experience in web applications. Ajax is described in an essay from James Garret from Adaptive Path. Google Suggest and Google Maps are good examples of what can be done using Ajax.

On this French article on Ajax from Framasoft, we learn that OpenRico is an open-source JavaScript library for creating rich internet applications and that implement Ajax.

You should also go to Michael Mahemoff's web site on Ajax called Ajax Patterns. It's a tremendous collection of design patterns based on Ajax principles.

Even if Ajax brings probably nothing really new in term of technologies, it has the creditable goal to put user experience in the top prio of web design.

English (US)   Javascript console always present  -  Categories: JavaScript  -  @ 11:04:27 am

Today, I realize that when developing advanced web applications, we always want to keep an eye on the Javascript console. Ok, in Firefox, there is a little red exclamation mark icon Exclamation mark (provided by the Firefox Web Developer Extension, see my article on this topic) when a Javascript error occurs. But if you are not enough concentrated on this exclamation mark icon, you can miss some Javascript errors.

This is a tip (found here) to open the Javascript console on the sidebar:
- Click on the Bookmarks menu and select Manage Bookmarks?
- Click the New Bookmark toolbar button
- Enter JavaScript Console as the name
- Enter chrome://global/content/console.xul as the location
- Check the Load this bookmark in the sidebar checkbox
- Click OK
- Use the created bookmark to open the sidebar

Very useful when developing and testing, isn't it?

French (FR)   RSS et la syndication de contenu  -  Categories: Blogs  -  @ 21:31:49

Vous avez très certainement entendu parler de RSS ou de syndication de contenu. Mais de quoi s'agit-il exactement ?

Créé intialement par Netscape, RSS a évolué dans le temps. La signification même de l'acronyme RSS a également changé passant de "RDF Site Summary" (RDF signifiant Resource Description Framework) à "Rich Site Summary" ou "Really Simple Syndication".

On appelle flux RSS un fichier XML décrivant tout ou partie d'un site web pour exploitation par un tiers. La syndication de contenu permet d'aggréger plusieurs flux RSS. Des logiciels spécialisés permettent de visualiser ces flux RSS on parle de lecteur RSS. Par exemple SharpReader est le lecteur RSS que j'utilise. Dans la suite de cette note, je vous explique - à titre de démonstration - comment utiliser un lecteur RSS pour lire les flux RSS de ce blog.

French (FR)   Conférence Java (Episode 4) : Les blogs  -  Categories: Blogs  -  @ 00:01:08

3ième opus de mon compte-rendu sur la conférence Java avec la présentation de Frédéric Casagrande sur le phénomène des blogs (contraction de web log ou journal sur le web), ces journaux sur Internet qui fleurissent un peu partout.

Quelques chiffres pour camper le décors : 3 millions de blogs en 2004, 10 millions en 2005. Le nombre de blogs double tous les 5 mois soit 40.000 nouveaux blogs chaque jour ou encore 2.2 blogs par secondes. Un blog étant composé de notes, on décompte 500.000 nouvelles notes par jours. Mais qu'est-ce qu'un blog exactement et comment créer son propre blog ?
