Except when a bug pops up somewhere. Ownership/Responsibility changes in sub-Planck-second time when assigning blame.

Sveltekit is the fullstack/SSR version of svelte (like next is for react or nuxt is for vue). I reckon learning one of them might be helpful to learn component-based SSR and its benefits, personally I do think they have a firm place in the future of webapps.

Vite I can highly recommend, it’s the best, fastest and least fussy bundler/builder I have ever used hands down (having used webpack briefly and packer for a while). Has some great features and is less of a pain to configure and get to work in my experience.

I would argue that the same things were probably true in western capitalist countries at the time (I have no evidence)

The CLI is scriptable/automatable and unambiguous when sharing instructions with coworkers. Both of these things make it very useful to know the commands. I do agree that it helps in some situations to visualize what is going on with a GUI/TUI though (neogit for nvim or magit for emacs are great if anyone is wondering), it can make things clearer at a glance.

And how does that work? How do you unmount the root directory of a live system and invoke a script?

Nextcloud is a FOSS fork of OwnCloud. Both projects are great in their own way, hugely successful and serve a lot of people very well. They just moved in different directions.

This is just one example of many. Ability to fork is super important to ensure that projects stay open source, like in this example.
