A couple of great milestones this week related to code contribution. Yesterday (perhaps the shot heard around the world in terms of software interoperability), Microsoft, for the first time, released code - some 22K lines - to the Linux community for inclusion in the Linux kernel (nothing more on this, as I think the trade press has covered it pretty well). Likewise today, Microsoft has released a free live services plug-in to enable calendaring, email, and instant messaging for Moodle (an open-source course management system). Further, the plug-in enables single sign-on which fosters a more seemless experience for users. For more information, please see Peter Galli's post on Port 25.
