A very clever immutable Linux distro, and is the basis for the excellent PiCorePlayer, a favourite of mine to run Squeezebox clients (and/or Lyrion music server) on any Pi
After finding Even Better TOML was eating all the memory in VS Code and that it is no longer maintained, I found an improved linter and formatter in Tombi.
It integrates with lots of editors and as a standalone tool with useful schema auto-complete and validation. I've found it fits in well with a Python ecosystem.
Best of all the author is really quick to respond to issues.
I agree however you forgot to mention the excellent Geany, which looks more comparable, and I think it be better for a developer to spend time improving that rather than porting a heavily MacOS based editor.
I find it strange that more people have not brought up the 'lost-sale' fallacy. By saying 'no' he actually loses out in the end because if the magazine is only looking for free photos, say to the keep costs down, it will just go elsewhere and the readership of that magazine will probably never know about that amazing photograph nor the photographer himself.
I fail to see what the problem is being 'stuck' with AMD, Linux, and Gimp. We we would no longer have the abuse of patents, propriety standards and DRM which in the end would benefit consumers.
Especially that the offer does not seem particularly good since they are only ebooks and seem overpriced in the first place. The physical books are already cheaper on Amazon and kindle versions cheaper still.
Edit: Just had a thought that any profit on these sales should really go to a charity or foundation.
