Weeknotes 2026.07

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 the registry is using Postgres as a database. A couple of SQL queries later, it seems like the garbage collector is working again.
Besides that, this week we saw the first launch of the heavy Ariane 64 rocket. The rocket was launched from Kourou.
