C#’s fanatic Ted Neward is amazed at how cool C#’s anonymous generic methods are. He then gives an example of a little program that filters some entries according to a critiria, using some generic types and delegates. It’s about finding all persons from a set of persons whose last name is “Neward”. Sam Pullara even showed his own version of the same program in Java and explains that IntelliJ IDEAallowed him to type roughly 10% of the characters of the program thanks to the wonderful completion and code templating capabilities of that IDE.

We’ve got PIM applications, all sorts of PDAs, rich client GUIs or webapps on the internet or behind the corporate intranet’s firewalls. There’s the MDA approach to generate apps from datamodels, orapplication generation engines that build applications dynamically thanks to the interpretation of a metamodel. All these applications and interfaces to store all kind of data, personal or business related, generally sports a fixed and frozen structure. New developments are always needed for evolving your applications, and costly redeployments and interuption of services are often triggered. Read more...

Sometimes, there are some unlogical choices that are being made: JBoss chooses JSPWiki as a base for their Wiki portlet in JBoss Portal. They choose to fork and trim JSPWiki (rather than contributing to it) to be able to embed a Wiki engine in their portal as a portlet. Fine. But why not choosing XWiki? XWiki: is a member of the JBoss Open Source Federation, can already be integrated in JBoss Portal, and moreover can also be integrated in any portlet container (The proof is that the eXo Platform already embeds XWiki as a portlet).

With the recent release of Google Talk, the fine chaps at Google entered the Instant Messenging market. The most clever step in that direction was their choice of protocol for their IM solution: XMPP. XMPP was popularized and standardized through the IETF by the Jabber software foundation with its famous open, secure, ad-free alternative to consumer IM services like AIM, ICQ, MSN, and Yahoo (quoted from their site). A particular benefit of choosing an open platform is that it takes advantage of available client GUIs for instance, and moreover, it can leverage specific and standardized extensions of the XMPP protocol – called JEPs.

Okay, Google released its Google Talk client and its related services. This all sounds good and well, but alas, for us, poor corporate users, we have yet to figure out if it’ll ever work through our nasty proxies (with authentication) and firewalls (port 5222 should be opened?). I’ve tried tweaking the proxy settings myself, but it didn’t work. Unfortunately. On paper, Google Talk certainly looks promising, taking into account the great services Google have come up with so far, but there’s really not much more than other competitors already provide.

At out last OSS-Get Together meeting in Paris last thursday, we’ve had the chance to have Thierry Templier, a Spring modules and a Jencks commiter, make an introductory presentation of the Spring Framework On our wiki, he made available two powerpoints in French: a big 118-slides presentation on Spring, and a specific one on Spring and JCA. That’s a lot of content to read for those of you speaking Molière’s tongue. Read more...

As stated on Javalobby: “The Guru of Groovy shares his Thoughts”! Well, it seems like I’m that Guru! And that’s been my first official interview. That was a quite fun and interesting exchange of mails between Andrew and me, and it allowed me to develop a few interesting points I never had time to explain. Andrew Glover, Vanward Technologies’ CTO, is a fan of Groovy. He wrote several great articles on DeveloperWorks in a “Practically Groovy” series". Read more...

Call me a geek, but I’d really love to buy me one of these little Wifi rabbits. The Nabaztag rabbit is a 23-cm high white rabbit with moving ears, and a set of flash LEDs of different colors. You can pair it with another rabbit so that when you move the first one’s ears, will automatically make the other one move its ears accordingly, even if your in another town or country (as long as you have a permanent DSL connection).

Pour mon anniversaire, Stéphanie m’a offert du matériel pour faire de l’aquarelle : un carnet à dessin et un coffret avec 16 couleurs. Comme le temps était plutôt agréable et clément ce week-end, nous avons décidé de pique-niquer auprès du Grand Canal du Château de Versailles. J’ai emmené tout mon attirail, et j’ai réalisé ma première aquarelle, que voici :
