I’ve written about stackoverflow.com, a place to ask and answer programming questions. And here is an other reason to use it: they have great error pages 🙂

And today I’ve learned something new on SO from Oliver Giesen (also, his SO profile): you can’t delete executable files which are “in use” (programs are being run from it), but you can rename them! I verified this with a small test program, and indeed, it is so. The same is true (not surprisingly) for DLL files. This trick can come in handy for cleaning malware.
