Some time ago my manager told me that I'd be one of three people maintaining the Windows builds used in our group, and this week is when I'm supposed to do that.

For those non-Microsofties, or at least, people outside the Windows group, Windows is a darned big codebase.  Building it takes time, so builds are scheduled overnight on some amazingly expensive hardware; and being so large, even if checkins are individually tested for buildability, build breaks still happen if two changes aren't completely compatible.  The probability in each case is low, but with enough activity eventually some happen anyway.

After a weekend of build breaks, I'm here at 5.30 am to fix build breaks, so that everyone will have a clean build by the time they get here.  Unfortunately for me, today it decides to 'just work.'  Still, it was fun to run here in the middle of the road due to lack of traffic...
