I've explained build breaks before and why they are big deal.

Last night about 10:40 the guy across the hall submitted a code change for review. About 11:35 someone else replied saying it looked good. At 11:49 the guy across the hall checked it in.

This morning I saw the request for a code review and took a look at it and thought, "Hmmm.... just one line was changed. I'll look at the bug report to make sure this is the right thing to do but it almost for certain should be fine as long as it passes the buddy build." Then I saw that he had already checked it in--without any mention of a buddy build. Hmmm... Okaaaaay.

Then I saw the email about the build being broken this morning. Then I saw the email about a new bug assigned to the guy across the hall. About 30 minutes ago another other guy showed up with a very large baseball bat* in the hall. I started laughing and went out to watch more closely. I stopped laughing and left when the thumping started. It wasn't going to be pretty.

I came back after a few minutes and the guy with the baseball bat was gone and I examined the guy across the hall for bruises. There were none showing so I'm assuming his clothes cover them all.

They take their coding processes seriously around here.
