Comments on what licenses mean—appropriate caveats about how these are my
notes for me, not for anyone else, and I'm to be held blameless for any
misinterpretation or bad spin I've put on this stuff.

You can pretty well do just about anything you want except resell the code
itself. You can sell a derivative product based on it. More to come someday...
You can't bloody do anything with GNU-license code except use it, display its
copyright and caveats, and make any derivative products based thereupon
completely open source. You also have to give back any changes you made.
Basically, if it's GNU, don't use it, go find help elsewhere or get a job in a
university where you're paid because the school doesn't care to sell products.
More to come someday...
