What a week. I upgraded to Fedora 43. Fedora supports the last two versions, and Fedora 44 was released this week. Somehow I managed that I am always a little behind.

Anyway. After the upgrade, the graphical userinterface didn't work anymore. And the home directory was not mounted anymore.

It …

This week was a week of a couple of first-timers. On a business trip, the train to Vienna used the Pottendorfer Linie between Wiener Neustadt and Vienna. And on the way back, I used the first time the Westbahn.

Despite that, the business trip was exhausting as usual. It is …

I had the second cold this winter season during the week. That was surprising. I can't remember when I had the last time twice a season. Thankfully, two coworkers figured out that I am just getting old ;-)

It was a busy week. After last week's Mythos madness, a lot of …

It was a short week. Monday was a holiday here in Austria. Despite that, it feels like a long week.

Because Friday and Saturday were the Grazer Linuxtage 2026. The biggest open-source event of the year in Graz. As usual, an event with great speakers.

And two friends from Germany …

In Austria, it was a quiet week because of the Easter holiday. And the Easter holiday is the reason why I published on a Monday.

What a wild week. On the security front, there was a lot of big news and breaches. Some called it the dawn of a new …

The supply chain attacks evolved this week. More and more projects are breached. It seems like Trivy was just the beginning.

Google published the M-Trends 2026 Report. As usual, it is an interesting read.

At work, we had a premiere. The first time two coworkers gave a little concert for …

Working with data is always great fun. I got two datasets. Both should have the same identifier. As usual, it is not the case.

Therefore, I spent a lot of time this week trying to figure out how to match those two datasets. The funny thing for me is that …

It was a quite successful week. We finally managed to migrate a legacy project to a dbt-based approach. The tests are looking very promising.

Instead of one giant SQL file containing a lot of inserts, updates and deletes, we now have a model for every step. We also included the …

I guess it is the first ever double header of the weeknotes. Last week, I already prepared some parts of the weeknotes edition for 2026.09 and went on Saturday to the skiing trip of our company. Every year we have the same bar for dinner after a day of …

What a week. It went by quite fast.

A colleague of mine had her birthday this week. She claims she always turns 25 on her birthday. So we decided to give her a special birthday card that she can now use every year. And if she decides that she is …

I think I finally found the reason why the garbage collector of our container registry didn't work as expected. At least some space was freed up. A nasty endless loop was causing the garbage collector trying to remove the same image over and over again.

The good thing is that …

It has been another though week. I am still not feeling 100 percent recovered from the cold I mentioned two weeks ago.

That was the reason I took some days off and went on a day trip where I decided at the bus stop or train station where to go …

There was another farewell party this week. Some former colleagues came too. It felt a bit like a class reunion.

I felt like I was completely left out in the cold on one project. That is a very unpleasant feeling. And made me think a lot. Does it make sense …

I worked the complete last week from home. The reason was a cold and that didn't want to infect anyone at the office.

And I am a person who thinks, if you could stay at home, stay at home with a cold. But there are always some people who think …

What a week. I was debugging an issue with our internal container registry. The Garbage Collector is not working properly. It took me a while to find the reason why it was not working.

After some investigation it seems like it has to do with the cosign process. The Garbage …

This week I had a round trip and used the new Koralm railway for the first time.

I took the train to Maribor and enjoyed the lovely snowy scenery. The next trip was to Bleibug/Pliberk where I visited the town. Afterward I went to the new station in St …

The first days of 2026 are here and I expected that it would be not that busy. Mongobleed is already under active exploitation and the 39C3 congress had some interesting talks. All in all, it wasn't as quiet as you would expect.

I played around with a new import model …

Die Woche war kurz und intensiv. Der Vorteil, wenn ein Großteil der Kolleginnen und Kollegen schon frei haben, ist die Ruhe. So konnten Montag und Dienstag noch genutzt werden, um einige Dinge fertigzustellen.

So konnten in diesem Jahr noch einige Dinge abgeschlossen werden und das Jahr 2026 kann mit weniger …

Man merkt, es stehen Feiertage vor der Tür. Diese Woche hat aus kurzen Nächten und langen Tagen bestanden.

So trifft man sich mit Leuten zu diversen Feiern, aber hat auf der anderen Seite auch viele berufliche Termine, da vor Jahresende die Projektpartner:innen noch gerne einiges abschließen (wollen).

Manchmal denke …

Diese Woche steht ganz im Zeichen der Eröffnung der Koralmbahn. Mit dem heutigen Fahrplanwechsel geht sie in Betrieb und bereits am Freitag fand ein großes Eröffnungsfest statt. Für den österreichischen Bahnverkehr ist es ein Meilenstein und wenn dann in ferner Zukunft auch einmal der Semmeringtunnel fertiggestellt wird, dann wird die …
