Welcome to the forum. Until a couple of days ago, this has been a sleepy sleepy town.

I also work as a programmer, live in Brooklyn, and do lots of stuff with music. I'm in the Brooklyn Community Chorus (BCC), which is lots of fun and has lots of folks in it -- and I work on jazz guitar and singing.

I've had a long term interest in learning about category theory, but it's hard to keep going when there is no practical context surrounding the study. But now we have a context to work in, right here!
