Interesting writeup, but 2 days to debug “the hardest bug ever”, while accurate, seems a bit overdone.

Though abs() returning negative numbers is hilarious.. “You had one job…”

To me, the hardest bugs are nearly irreproducible “Heisenbugs” that vanish when instrumentation is added.

I’m not just talking about concurrency issues either…

The kind of bug where a reproduction attempt takes a week, not parallelizable due to HW constraints, and logging instrumentation makes it go away or fail differently.

2 days is cute though.

Math.abs(Integer.MIN_VALUE) in Java very seriously returns -2147483648, as there is no int for 2147483648.

You inspired me to check what .NET does in that situation.

It throws an OverflowException: ("Negating the minimum value of a twos complement number is invalid.")
