YABGR! Yet Another BeGeistert Report! Rene (the yak man), after travelling for 245884683 hours finally returned home in the US, fresh from his Coding Sprint in Dusseldorf. As mentioned before here at ICO, he was working on Haiku's Debugger, fixing bugs and adding features, such as typecasting.
He has now wrote his report on his efforts while at the youth hostel (by the way, if you're visiting Dusseldorf, even when it's not for BeGeistert, I highly recommend it), going into deeper detail on what he's been working on and also giving examples on how to use the new features. So head over and enjoy his report and the pretty pictures!
