My one nitpick / thought would be that the terms of service[1] are a bit limiting. I wasn't expecting Creative Commons (although it's always great to see CC-licensed educational materials), but expressly forbidding any commercial use is a bit of a shame - what if someone is learning as part of a job? The terms have been auto-generated by a ToS generator[2], so this wording may not be fully intentional.
I can tell you it isn't intentional and you comment reads fair to me. The main thing I want to prevent is that people are teaching using this material without linking back to the source. It's the whole "people claiming it as their own" that I'm keen to omit. I used a generator in this case because I'm not well versed with legalese. I'll gladly hear any advice on this.
for code that simply showcases features of a programming language, such as the "args / kwargs" video, that's not copyrightable because it's not a novel application, but it may come into play for the more advanced topics.
really great project, by the way. i can see myself using and recommending this. your site brings to mind khan academy, which got me through three semesters of calculus.
I've started a thread on this on github here; https://github.com/koaning/calmcode-feedback/issues/61.
Creative Commons have a license chooser[2] to help people find the right license for them. It asks two simple questions:
* Do you want people to be able to share adapted versions of your work?
* Do you want people to be able to use your work commercially?
And from your answers to those, recommends a suitable Creative Commons license.
Of course, there are plenty of other licenses out there, but Creative Commons is good because it is widely known and used.
