The good news for this Friday the 13th was that the "Check Engine" light on my car threw a code that is usually a transient glitch and that didn't require anything to be done. As a bonus, I got the oil changed. :)
Work, on the other hand, is being challenging. Our QE people are specializing in errors that only they can reproduce today. Some of them are errors that we know of that aren't being addressed in this fix.
