Since we found a Phorum bug in the Facebook thread, I thought I'd mention another really conspicuous and memorable programming error I saw (I'm referring to ones I've seen in person;
The Daily WTF has a whole collection of others).
My brother and I used to stay up late on New Year's Eve. We were watching the Times Square celebration on I believe it was ABC on December 31, 1999. ABC had a countdown timer displayed on the screen (in some horrible font like Comic Sans, which is a bit of a WTF in itself), and it would count down like this:
4:03
4:02
4:01
4:00
3:60
3:59
In other words, they were adding an additional second every minute.
I pointed this out to Mark, my brother, and triumphantly said "I've found the Y2K bug!"
(They fixed the clock before the crucial countdown began)
