at least in computer languages. Over the years, I've programmed in Ada, some assembly, several dialects of Basic, C, C++, CLIPS, dBase, Focus, FORTRAN, IBM JCL, JOVIAL, Modula 2, Pascal, and a few others used for small projects, like Aspect. Computer langauges come easily to me, and octal is for losers who can't count to F.

As for human languages, I've had training in German and Hebrew. The Air Force tried to make a Hebrew linguist out of me back in 1978. After 4 months of 40 hours per week instruction in the language (and a near ulser), we all agree that it was a bad mistake. In the end, I still remember a few dozen words of the language. There's one word that I'll always remember, the word for commander. Spelled phonetically, it's mafuckhead. I think I know the origin of that word.
