Weeknotes 2026.41

Another busy week, and sometimes I wonder how fast a week can pass. I had to deal with a lot of administrative tasks.

But besides that, I was once more impressed by the Postgres feature set. I had some trouble with a foreign server, and after some research I found that this problem was already solved and I just had to turn on an option.

Today was the Marathon and big parts of the city were closed. A record number of runners participated.

Big breach

There was a data breach at Denmark’s national population register. And according to a report, the account used for the breach had a highly insecure password: 123456.

Mistral

It was a week with up and downs for Mistral. They announced a new model: Le chonk.

And on the other hand, Ecosia announced that they will replace Mistral with Chinese open-source AI.

Lakes

A megacomplex of artificial lakes is built in Germany. Former coal mines are transformed into a new world of lakes.

Almost like Lake Como: Germany transforms former coal mines into Europe's largest lake landscape
