Edit: thanks for clarifying support for the Deck

There is “Oscilloscope” which can show frequencies and their intensity

Great, heard good things about OpenTTD! Do you game it directly on Steam Deck Controller or on Desktop with Mouse, Keyboard?

Thanks, I assumed so! :)

Great Game, for now i primarily play it on Android Phone. Easy to begin, but easy to die with one wrong click the game can be lost after hours of trying to get to the amulett!

Great Thanks for your write Up. I would love the idea that Steam Deck comes preinstalled with an Open Source Game like Xonotic!

FitoTrack may be suitable for that.

If the Map is not fitting totally you can even correct it on OpenStreetMap.org by yourself

FitoTrack is a nice open source fitness tracker which shows the path on OpenStreetMap background. It logs position and speed data.

You can create a custom workout which shows you the current speed instead of average.

What do you actually need it for?

How to watch YouTube on Steam Deck? Via Desktop Mode?

Fully open source, End to End Encrypted alternative to Google Photos and Apple Photos

1. Easier installation.
2. Mint configuration of desktop settings
3. Mint tools (Warpinator, Hypnotix)

But where to get the AppImages from? Who’s maintaining? How to do Security Vulnerality Tracking for them?

Don’t panic!

I don’t get your point. Why should somebody do this every day?

As the experience from other users in this thread, it seems not extremely rare to have an overgrown ~/.cache/ folder. So checking it from time to time is a good advice. If we all do this for a time, and create bug tickets for software which is not cleaning up. Then this problem will hopefully go away with future software releases.

Because some users experienced accidential grows like OP had 160 Gbyte. So general advice for linux users can be stated as: Check your ~/.cache every now and then

Critical systems/servers shall better be monitored as you suggest.

not necessarily during runtime

So OP’s headline should be saying instead: Reminder to CHECK your ~/.cache folder every now and then

I always felt that there should be some user directory like /tmp/ which will be wiped regularly.

Is it safe to clear ~/.cache/mozilla/ while Firefox is running?
