As mentioned in the AI recap, I am experimenting with a new format. And I think Postgres deserves a more focused recap than the Weeknotes could offer.

Another short week here in Austria. That usually means a couple of intense days.

We were evaluating a new Software. So I downloaded the latest container image and started it. We wanted to authenticate against our Keycloak server, but it didn't work.

I was already starting to feel a little …

It was a quite successful week. I was able to successfully complete many of the tasks I had to do. Some tasks made me feel a little bit giddy.

This week a heatwave started, and we already had over 30 degrees. But the week finally brought a little bit of …

I've been to the black forest, and that is the reason I didn't publish last week's weeknotes. I thought let's try this week one more double-entry bookkeeping. Due to a long weekend here in Austria, the weeknotes are published on a Monday.

The time at the black forest and the …

Finally, this week brought some rain. It was very dry the last couple of months, and in some parts of Austria there was almost no rain the whole year. The parks and meadows looked already like they look at the end of the summer.

Although it would have been better …

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 …

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

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 …
