my worst dev sin:
Commit and go home on a friday not waiting for the build to pass.

Tons of notification from counterparts the following monday

In a properly set up CI system this shouldn't be a problem. These builds should be gated before merges can take place.

Been burned by this exact scenario. These days I just wrap the command with a tiny notifier (cmdn) so I get pinged the second the build actually passes or fails, instead of finding out from a pile of angry messages on Monday.
