Heading into a long (and quiet) weekend for many folks in the US, I thought I would highlight some useful open source and shared source projects on Codeplex, particularly after reading eWeek's gallery of the Top 25 Most Active Open Source Projects on Codeplex. There's some practical tools in the article - including an open source blogging engine, SQL sample applications and a cool mapping application. What many folks may not know is that there are over 2,000 projects available on Codeplex. Check out, among others:
IronRuby also released last month (it lives on RubyForge) - John Lam has more details here. If you're interested in learning more, I would also recommend checking out our Sourceforge landing page that highlights open source projects and programs at Microsoft. While you're on Sourceforge, we have some interesting projects over there as well - including the WiX Toolset and the OpenXML/ODF Translator.
Enjoy the weekend (and the downloads).
