A few weeks ago, I joined an open source project that was just starting up. Its called Fluent NHibernate and provides an alternative to XML based or attribute based mapping of NHibernate domain objects. The project owner James Gregory does a much better job of explaining it than I could.
Why am I only mentioning it now? Well during the first week I was too busy trying to get up to speed and make a useful commit to blog about it. As for the last couple of weeks, I've been holidaying in France and Italy and its been hard enough just keeping up with my RSS and mailing lists.
It has been a great experience so far. The other contributors are really friendly and smart, and I am impressed by the sheer volume (and quality) of work being performed. I'm learning how to use Subversion and really missing continuous integration (yes I already broke the build, managed it on my 2nd commit).
Incidentally, this is my first post using Windows Live Writer. It seems nicer than the Blogger web interface.
