I disagree. Especially where the resulting python program is not a transliteration (which it certainly won't be) of the original BASIC programs. As well, these programs implement well-known algorithms and games. There are only so many ways to implement certain algorithms, and each implementation is going to be closely similar. The games and algorithms in his BASIC programs are by no means original or not well-known and well-discussed. Also the quoted copyright notice is for the entire work, which is to say the book. Chris is in no way reproducing the guy's text in whole or in part--I note that the notice says nothing about fair use. That's not to say the original book author couldn't pursue a copyright claim, even if it's without merit. As to the question of assigning a copyright license to code, in this case I suggest just releasing the code marked as public domain. The programs are small and trivial. If you do not release it explicitly as public domain than you must release it under *some* license, because to not do so prohibits anyone from doing *anything* with your code by default, something a lot of githubbers seem to forget. Also as long as the code is entirely your work (and it is, despite Marko's assertions about derivative works), you can change the license at any time. -- https://mail.python.org/mailman/listinfo/python-list
