Quite recently, discovered this very interesting blog from developers to developers, called Alt Dev Blog a Day. A lot of pretty interesting posts daily and very good hints etc for all levels of coders. Most of the topics are close to game developers but it serves nicely all who need some inspiration for their daily development process.
(and yes, I follow it via rss feed, just like most of the interesting sites all over the internet).
Edit: As a bonus, got another one for you to follow: Cbloom rants. Hope you all find these useful.
