Weeknotes 2026.19
Posted on So 10 Mai 2026 in Blog
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 if the rain happened a couple of hours later. It was during the business run in Graz with thousands of runners. But at least, finally some rain :-)

Story of the week
Figma has written about their new connection pooler: PGKeeper. They used PgBouncer before that, but the outgrowth of the project has been so impressive that they decided to replace it. From the writeup, PGKeeper seems like a lot more than just a replacement for PgBouncer.

Chrome and AI everywhere
It appears that Chrome silently installs a 4 GB local LLM on your computer. Isn't that a beautiful world we are living in?
