Jonathan Caves works on C++ compilers at Microsoft, and has started a new blog. His first entry is about LKG, or Last Known Good, the strategy for releasing fairly new compiler builds within Microsoft. Another early entry is about Gauntlet, the automated distributed regression testing system used by the C++ development team. (I’d post direct links, but I think his permalinks are out of whack.) Interesting stuff even if you aren’t a C++ user.
