I submitted the only cool “Trick of the Trade” that I could think of to Matthew Baldwin’s site and it was posted (hooray). Although I titled it “Violinist” it works for violists (in fact the first time I saw it done was by a violist) and probably cellists as well. I tried to think of a programmer trick of the trade, but I figured the Internet is overrun with those and most of them are just fuel for philosophical arguments anyway.
