Hello, fellow programmers. I am a classical pianist, and, as of late, I now feel confident enough in my abilities to call myself a programmer. I began programming just over a year ago, sometime around August/June of last year. I started learning here at Code Abbey, which has been a blessing. Without this site, I'd still be light years behind. Anyhow, I started with Python, did over 100 problems with it, then moved to C# (which I still very much like), and, recently, have begun using Scheme (although I wish I never had; I can't stop using it now!) and the functional paradigm. So these days I'm spending my time rewriting old programs in Scheme. So, we'll see where this leads!
