Yes, I have achieved a rite of passage for anyone who works in a software development organization: I broke the build. I checked in a new version of the online Help, and now the code won't compile. There's possibly a score of programmers who are twiddling their thumbs waiting for me to get the fix in. (So, why am I on LJ? My Help is compiling. Nothing I can do until it's done.)
It's really quite a special feeling.
Now I need to develop an appropriate pre-checkin test to prevent this from happening again.
