Excellent short video showing visually how an Iterative and Incremental Development model can help to prevent software depreciation by maximizing the generated business value over time and keeping it high - or even higher - by welcoming changes. At the end, this video illustrates the benefits of Agile over a traditional approach.

Hibernate 3.5.0-Final is out
Hibernate 3.5.0-Final has been released yesterday (no no, this is not an April Fool) and this is great news. Congratulations to the Hibernate team. Noticeable changes include:
And for the impatient Maven users, you can get the new artifacts from the JBoss Maven repository.
- Hibernate Entity Manager, Annotations and Envers are now part of Hibernate Core (so they now have the same release cycles and version numbers, no more compatibility matrix hell).
- Full support of JSR-317 (JPA 2.0). Yeah baby!
- Support of a new second level cache provider (Infinispan which is actually a data grid, pretty interesting).
- Support for JDBC 4.
- And more, see the official announcement.

Scrum methodology video
In this less than 6 minutes video, Bruno Sbille and his team demonstrate how they applied Scrum on a real-world project. No advertising, no lobbying, just pure experience sharing in a very didactic way. Warmly recommended to everyone interested by Scrum agile software development methodology.
Thank you Bruno for this work and for sharing it:

Ubuntu and maven2
I don't know how I missed this but I just discovered that maven2 is available in the current unstable release (Hardy Heron).
So, happy Hardy Heron users, if you want to use maven2, installation can be pretty straightforward:
$ sudo apt-get install maven2
Et voilà! After a few seconds and the download of a bunch of new dependencies and files, maven should be installed and working correctly. This can be verified using the following command:
$ mvn --version
Which should should print something similar (at the time I'm writing this) to:
Maven version: 2.0.8
Java version: 1.6.0_06
OS name: "linux" version: "2.6.24-12-generic" arch: "i386" Family: "unix"
It's not that it's complicated to install maven manually and I was happy with my current setup and will keep it for various reasons (mostly because I'm using 2.1-SNAPSHOT) but a well integrated package is always nice and helps: no ENV variable to set up, no PATH to modify...
Actually, this is precisely one of the reason I really like Ubuntu : Apache, Java, Ruby, Python, Scala, Groovy, PHP, Maven, Ant, MySQL, PostgreSQL, Tomcat, Glassfish, Subversion,... you need something? just "sudo apt-get install" it.
Ubuntu is definitively a great development environment!
Note: Gutsy Gibbon users can try the backports available in Matti Lindell's Personal Package Archive as mentioned in this comment or wait for the release of Ubuntu 8.04 which shouldn't be a big issue as it will occur in a few days now.
