With jupyter notebooks in a devops perspective you could just build a process to export the notebooks to standard py files and then run them.

There are actually a lot of git hooks that will actually expoet/convert .ipynb to .py files automatically since notebooks don’t work great with git.

Am I an idiot or isn’t the “pip vs conda vs poetry” line talking about package management?

With things like wsl, conda has also become less useful. Anaconda is terrible software and the need for conda managed packages is mostly lost outside of the windows OS in my opinion.

App stores and game engines are examples where you are paying a percentage of revenue. Not that it makes this scenario make any more sense, but there are models out there that operate this way. However, in both you are working in pretty locked down environments.

I’ve used Ubooquity on and off for this. It has some nice features, but isn’t open source.

I don’t like Ubooquity, but Calibre somehow seems worse.
