Debian Stable as base OS, then activate unstable repos in a sandbox/container. Maybe even Distrobox for newer Apps.

Some people use carbon foil for cars to customize their thinkpads.

A german magazine just made a video on that topic. You can activate english subtitles.

They tested a bunch of smart tvs and tv-sticks and their network activites.
They say that roku devices were the most privacy friendly tv-sticks.

And if you dont care about warranty voiding, open the tv and tape the things you dont want. Mic, cam, etc. Its probably the cheapest option

There are some security, privacy and stability advantages of other init systems over systemd. But for most people systemd should be fine.

Also getting encrypted dns to work with systemd is pretty tough and unreliable in my experience (with debian and opensuse). See here https://github.com/DNSCrypt/dnscrypt-proxy/wiki/Installation-linux

The closest thing to clean install is Ameliorated AME or Atlas OS. Check that out if you really need windows.

Use some kind of hierarchical folder-structure like the Usenet does.
Something like: unix.desktop.theming for all your desktop ricing/theming stuff, unix.lx.debian.doc for debian documentation, win.win10.winget for everything related to winget on windows 10, rl.bureau.finances for your finances, accounting, etc. ...

You can use the Browser Extension "QuickCut" to save your bookmarks in folders. Its really helpful when you work on a bigger project and have all the documentation weblinks at hand.

Never tried it but there is Franz and certain plugins for Bitlbee and Pidgin Messenger

Beagleboards are great. Good Support and nice community. Nearly as good as Pi. I used BBB because it was the only open hardware SBC available in my area.

BTW: Please recommend me other good Open Hardware/Open Firmware SBCs. I am always looking for something new. Maybe for a Router or Selfmade-NAS.

go to Yast -> Software Repositories and add the Brave Repo. Now you can install it in Yast Package Manager.

You can also install it with "opi" from terminal: "sudo opi brave"

OpenSuse Leap. In YaST (its system settings tool) you can do everything from a GUI. No cli, no config files, no tinkering.
