Weeknotes 2026.15

Posted on So 12 April 2026 in Blog

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 spent the week in Graz to visit their old temporary hometown. And actually, I still found some time to work in this short week.

The announcement of the week came probably from Anthropic. I guess many people are really curious about Claude Mythos, but it will probably take some more time to get my hands on it.

Story of the week

What a week for Anthropic. Everybody is talking about their new frontier model called Claude Mythos. They claim it is too good at finding bugs in code, that it is too dangerous to release it now into the wild.

Therefore, they announced Project Glasswing, where Anthropic brings together the big tech companies, so they can fix some bugs in their code, before releasing Claude Mythos to the public.

AISLE, a company specialized in finding bugs, claimed that even small open-weights models could have found the Claude Mythos showcase bugs. So I guess we will have to wait and see.

Postgres and the world of data

Webloc

An analysis by Citizen Lab found that law enforcement agencies used an ad network system to track millions of devices.

Hacked supercomputer

If that is true, it is probably a huge thing. A hacker has allegedly breached one of China's supercomputers and stole around 10 petabytes of sensitive and classified information. I am kinda surprised that the Chinese systems didn't catch the exfiltration of such a massive amount of data.

AI

Google AI

There is a New York Times article about the accuracy of Google's AI overviews. It seems like one out of ten Google AI overviews is wrong.

Sam Altman

What a wild week for Sam Altman. The New Yorker published a story about the CEO of OpenAI that paints not the best picture of Sam Altman. And a couple of days later, a man threw a Molotov cocktail at Altman's home. I mean that is pretty scary and insane.

Artemis II

The NASA published some incredible Pictures: Artemis II Lunar Flyby.

Using Firefox extensions extensively

It turns out there’s only 84 thousand Firefox extensions. That sounds feasibly small. That even sounds like it’s less than 50 gigabytes. Let’s install them all!

When a blog post starts like that, you know it will be wild :-) It sounds like a funny experiment. And due the fact it went viral, one extension author actually replied to the blog post and explained why he did what he did with the extension.
