I'm not sure how well it would work in a self-hosted or server-type context, but GPT4all has built in RAG functionality. There's also a flatpak in addition to the Windows, Mac and .deb installs.

I've had no problems with the Discord flatpak and updates. I use a KDE variant of UBlue and the package manager prompts me to update all flatpaks when I start the computer (whenever there are updates available), which I do with one click.

For a new user, i would think that individually managing package updates is probably not a desired workflow.

Oh, that's very interesting. I knew about flak in the military context, but never realized it was the same word used in the idiom. The idiom actually makes a lot more sense now.

What instructions or guides do you recommend?

I experimented with self hosting RSSHub a while back and I do believe you could get past rate limiting on Instagram by configuring the app with your personal Instagram account credentials. I think those without an Instagram account were advised to follow pages via the Pikuki route instead.

Amaze File Manager can do this.

Thanks for the additional reading and information. Maybe it's just me, but I feel like I hear about a security vulnerability in "processor microcode" or packages or other software basically every day. As a relatively non-technical user, it's always very difficult to tell how much these things actually matter for normal users. Flatpaks are incredibly convenient because they "just work" and are easily compatible with immutable distributions. For better or worse, I suspect many people are not going to be dissuaded from using them by hypothetical/abstract security risks.

Can you say more or provide a source on why you shouldn't use a browser as a Flatpak? Is it just because the sandboxing is potentially weaker?

I guess so. I hit the grub menu when booting and I see the image version changing there as well.

Any tips on how to actually learn this keyboard? Do I just force myself to use it as much as possible until the movements start to become muscle memory? How long might that take?

A static site generator like Jekyll hosted on Github pages might be a good option. It's free and easy-ish to configure without knowing much code since there are an abundance of open source templates around.

Has anyone gotten the Andriod app working? I installed the APK and it will activate from OpenBoard and show that it's listening, but it won't actually output anything into a text field.
