More I hop jobs a lot. I was using C at the beginning of my career. Lately, I'm using C again (and more importantly, using arcane C skills that no one has anymore, doing a 32-64 bit port). I picked up Java in 2001. I've done a fair bit of Ruby, too. Doing Python in the current gig, which is mostly new to me but trivial to learn.

The point is, I haven't had to deal with C for a long time. It's odd to be doing it again.
