"Bitcoin and Ethereum use the same amount of energy as the whole of Austria

And then there’s the environmental problem. The environmental problem? Aren’t we talking about digital coins? Yes, which makes it even stranger. Solving all those complex puzzles requires a huge amount of energy. So much energy that the two biggest blockchains in the world – bitcoin and Ethereum – are now using up the same amount of electricity as the whole of Austria."

@janneke @civodul So I just found Microsofts "Azure RTOS" also has a GUI component named :


Skimming over the documentation[1], Azure RTOS is the well known ThreadX RTOS rebranded after being bought by Microsoft. It clearly targets the IoT space on Cortex-M class devices.

Nach gefühlt endlosen Herum probieren:
Warn-App (Nina, Katwarn) Meldungen ohne Google Play Dienste, microg oder unsauberer Appinstallation erhalten
LÖSUNG: Man geht auf die Seite warnung.bund.de/meldungen
(Offizielle Seite vom Katastrophenschutz) dort eigenen Landkreis suchen und auswählen. Erscheint dann im Filter (über Karte) links neben dem Landkreis ist ein RSS-Feed (mit Desktop Seitenversion einfach zu treffen 🧐). Den abonnieren und bei Neumeldungen auf Alarm stellen, fertig.

Hm, ok. Removing solves the problem. So it was not a problem, but an external component that I added manually. I'll check later if there is an update for turboprint with a fix.

Oh no. I see a process "systemd --user" which is the parent of a lot of gnome daemons including tracker-miner-fs and it runs as *drumroll* user "lp".

Now where is this started from?

But at least I reached one of the goals of the upgrade. is now new enough so that sound works in a Win 10 virtual machine.

This was one of the remaining problems for me switching from to . 😤

All I have to fix now is -miner-fs - the log says the restart count is now at 1228 and it is still convinced it should run 😰

I do see an error message that -store cannot initialize its database "/var/spool/lpd/.cache/tracker/meta.db". Why on earth would it put its database there? No idea 🤷‍♂️

Also for the first time ever I ended up with a periodic behaviour for "apt dist-upgrade". Two packages were playing ping pong. One run installed "libapache2-mod-php7.3:amd64" and removed "php7.3-fpm:amd64" and the next call did the opposite ad anfinitum.

But then again, I had to do some manual package removes before the dist-upgrade ran at all, so maybe this broke things. In the end I was able to fix all problems so dist-upgrade is now idem-potent quiet.

Now that I was suspicious that there may even be entire packages missing, I checked the set and indeed "xserver-xorg-input-all" was also missing 😭

Having installed that I at least got a working gnome desktop again. Phew.

I really wonder what led to those problems.

After some headscratching I found out that important components like gnome-shell were missing 🤔 "apt install gnome" at least fixed that.

So the next login attempt got me to the gnome desktop but alas still with no working mouse.

Upgraded one of my machines yesterday from buster to testing. All in all it was a frustrating excercise.

The reboot after the update began fine with gdm3 presenting a new login screen with working mouse. But entering my password I got a black screen with a gnome terminal without focus that did not respond. Mouse was also dead.

Recurring offer reminder: I'll help / mentor / teach / tutor / troubleshoot with anyone who wants to learn git for basic version control, collaboration, managing personal projects, or for a day job. I'll work to connect people with mentors other than me if they prefer - no need to explain why.

Same for bash, command line tools, and so on.

I want using & contributing to FS/OSS to be easier for way more people.

Boosts appreciated!!
