It happens all the time.
Only yesterday I found a foriegn site(I.e not in english) that has a whole tutorial on 2d particle systems, built around my code. http://www.gameprog.it/?resource=466 (Translated version -> http://translate.google.com/translate?hl=en&sl=it&u=http://www.gameprog.it/%3Fresource%3D466&prev=/search%3Fq%3Dsolidkojima%26hl%3Den%26lr%3D%26ie%3DUTF-8%26oe%3DUTF-8
He did credit me, so I didn't fire off any e-mails.
Another time someone posted a packer lib for files on here, was my entire lib(Tid packer, still on code arcs i think), just renamed functions. That one I did get removed though.
2d lightmappers..I invented, this bang, everyone's doing it, same technique.
I could go on and on. I don't mind that much tbh, because sure it happens, but also you have to consider we nearly all learnt ourselfs using other people's code and techniques.
