I accidentally found a security issue while benchmarking postgres changes.

If you run debian testing, unstable or some other more "bleeding edge" distribution, I strongly recommend upgrading ASAP.

oss-security - backdoor in upstream xz/liblzma leading to ssh server compromise

In Austria, inflation is way above the EU average. There's no end in sight. This is especially true for basic needs like energy and food.

Our government stated in May that they'd build a food price database together with the big grocery chains. But..

I was finally able to add a fully #punycode domain (such as はじめよう.みんな, or xn--p8j9a0d9c9a.xn--q9jyb4c in computerspeak) in the M365 admin interface. This must have been a recent-ish change.

Some parts of the Exchange admin center still claim the address format is invalid when choosing the domain from the dropdown, but I managed to assign it via PS.

Gmail seems to be able to send to that address just fine, #Hetzner webmail OTOH nopes right out. I wonder what else breaks :-)
