Agrrr... I hate to do code review of that shit! I hate to write docs for that shit! I hate to talk to PM! I hate dumb developers!
But there are several things about programming that make me calm and happy. When I'm thinking about one of those things I just sit and smile.
One such a thing is the process of upgrading gcc from sources.
1. Build new gcc with old gcc.
2. Build new gcc again with newly built gcc. Call this build A.
3. Build new gcc once more with build A. Call this build B.
4. Compare that A and B are exactly identical to the last bit.
5. You now have self reproducing compiler.
That is just beautiful and literally gives me chills.
