Das Update zu Mastodon v4.7.0 habe ich, wie auch bei anderen Versionen zuvor, einfach gemäss Anleitung aus den Release Notes gemacht.
Die einzelnen Schritte haben dabei einwandfrei geklappt.
Kurz danach meldete mir das Monitoring aber, dass mastodon-streaming@4000.service nicht mehr laufe.
Im Log sah ich dann auch eine Fehlermeldung: TypeError: webidl.util.markAsUncloneable is not a function
Das Problem lies sich dann zum Glück rasch lösen.
Über "Verknüpfung zu Meine Dateien hinzufügen" lassen sich SharePoint Bibliotheken mit OneDrive verknüpfen.
Normalerweise sind die aber via Graph-API und auch in Tools wie rclone nicht sichtbar.
In unserem Haus steht eine Wärmepumpe des Typs CTA Optiheat 1-11es.
Da wir in der letzten Zeit mit der Temperatur des heissen Trinkwassers nicht zufrieden waren, habe ich mich der Herausforderung gestellt, an Metrikdaten zu kommen.
Recently I got an new exception when I started a Spring Boot application for development:

I currently use bash/zsh aliases to simplify setting up tunnels to our database servers.
In an article in the Linux Magazin I read about boring.
The tool looked nice as it allows a well readable config file and opening the tunnels in the background.
As boring (or rather its ssh_config library) does not support Match in the ssh config, it is no real solution for me.
Luckily I read ssh itself can do the job quite well without 3rd party tool!
evcc does not provide an metric endpoint for prometheus (see evcc discussion #7306).
With pollect, its easy to publish the evcc data for prometheus.
With my former Yubikeys I was used to use yubikey-oath-dmenu for (T)OTP.
As I found no similar solution for Token2, I wrote a wrapper script around t2-cli.
I recently started to use Token2 "T2F2-PIN+ Release3 TypeC" Keys to store SSH Keys use them for (T)OTP and U2F/FIDO2.
But GnuPG did not work out of the box on my Arch Linux notebook.
To enhance the restore speed for PostgreSQL databases, the pg_restore command running the most time-consumping steps concurrently by providing the number of jobs with -j/--jobs.
Unfortunately the parallel restore can fail when restoring foreign keys due to not yet restored tables:
pg_restore: error: could not execute query: ERROR: there is no unique constraint matching given keys for referenced table "page"
Command was: ALTER TABLE ONLY pagecontent
ADD CONSTRAINT "$1" FOREIGN KEY (page_id) REFERENCES page(id);
