Sounds overkill just for backing up files.

DHT is autonomous and does not require a tracker. Usually it is only used as a fallback as a regular tracker is quicker. It’s p2p, and is split accross people hosting it.

my favourite is Amazon’s:

• buy without prime (2$ shipping fees)
• buy with prime (free shipping)

exept you must pay amazon prime 10$ and it’s a monthly recuring subscription.

I’m fine with Rofi. I’ve used xfce4-appfinder also, it’s less minimal, not configurable (good graphical defaults, might be what you want).

I use BTRFS for the same. Being able to check for and repair silent corruptions is a must (and this is without needing to read the whole drives, only the actual files). I’ve had a lot of them over the years, including (but not only) because of a cheap USB controller also.

the Android VLC is absolutely different from the desktop version.

I use Signal, but I’m unable to force everybody to do the same.

Any chance to use Whatsapp on /e/ ?
