Site that sort of provides active JavaScript notebooks, with a view to doing most/all of the work on the client side. I was sort of hoping there'd be a self-host option or something and I'm not seeing that. On the other hand it could be a good tool for tinkering with and prototyping code.
Things you're probably not using in Python 3 - but should
Handy little post that details some of the real headline changes that have taken place in "recent" generations of Python 3. I'm happy to say that I make use of a good few of these already.
Neat site that provides an animated view of the history of a file in git (well, mostly on GitHub and similar forges). Could be handy if ever needing to demonstrate how some code evolved.
Many biomedical research graduate programs have been compelled to “go online” with little or no notice due to the COVID-19 pandemic. Since many professors are distinctly uncomfortable in front of a camera, students may not get exposure to some of the topics that they might have expected. Since my move to South Africa in 2015, I have tried to deposit video on YouTube (and PDFs of the slides to Google Drive) every time I have delivered a lecture for students. Since I teach a fairly broad range of coursework, the catalog of topics may be useful for students working from home or for departments that are trying to ensure their students get the training they need. This page indexes the series of lectures I have made available. I hope you enjoy watching them as much as I have enjoyed creating them!
