The Chicago technology scene is tight. I just had a meeting with a guy I worked with from 2003-2004. Back then, we were both consultants on a project with a local financial services company. Today he's CTO of the company that bought it—so, really, the same company. Apparently, they're still using software I wrote back then, too.
I love when these things happen.
This guy was also witness to my biggest-ever screw-up. (By "biggest" I mean "costliest.") I won't go into details, except to say that whenever I write a SQL delete statement today, I do this first:
WHERE ID = 12345
That way, I get to see exactly what rows will be deleted before committing to the delete. Also, even if I accidentally hit <F5> before verifying the WHERE clause, all it will do is select more rows than I expect.
You can fill in the rest of the story on your own.
