Can you recommend any of the existing Matrix clients?

Xubuntu comes with Ubuntu’s proprietary snap system. I don’t trust snap and users report about bad performance and disc space usage.

As an alternative there is Linux Mint 22 XFCE Edition, which is based on the Ubuntu 24.04. sources:

It’s a good idea to create a more decentralized solution to share your parkour spots.

Unfortunately osm.org does not support custom POI lists.

The german OSM community is hosting a Umap service, where you could create a custom POI map. (https://umap.openstreetmap.de/en/)

The map can then be shared and the POIs can be downloaded as gpx, kml or similar file. This file can then be imported into any Map Apps.

For the photos… If you get the permission to put these under a Creative Commons License, then you can upload them to Wikimedia. Then put the link into the description of the POIs in the Umap

And here is the chart to follow the progress:

https://taginfo.openstreetmap.org/tags/natural=tree#chronology

We should see a saturation arround 3 trillion trees. (1)

You can easily help achivieving this goal by reworking natural=tree_row and adding single natural=tree into natural=wood areas :) I know, some say this is discouraged, but we really need to map EVERY TREE!

The Linux Mint Upgrade process for Version 21.x to 22 still needs manual console commands and a sudo or root user with graphic access.

It would be nice if Mint will improve to a more integrated upgrade process in future.

Shops are still closed in Germany today. Let’s see tomorrow. Nevertheless thanks for this hint.

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?

Not everybody has an 3d printer… Any is the printed plastic UV resistant to be mounted outside for several years?

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?

Don’t Panic!

Interrupt Labs security researchers were the first to demo a Samsung Galaxy S23 zero-day in an improper input validation attack, while the ToChim team exploited a permissive list of allowed inputs to hack Samsun’s flagship.

and …

In all four cases, the device ran the latest version of the Android operating system with all security updates installed, according to the contest rules.

Can the Fedora Flatpaks be browsed and downloaded for other distros?

Even if you have trust. There can be security vulnerabilites in apps we are using. Flatpak seems to not really help in any way.
