Weeknotes 2026.17

Posted on So 26 April 2026 in Blog

This week was a week of a couple of first-timers. On a business trip, the train to Vienna used the Pottendorfer Linie between Wiener Neustadt and Vienna. And on the way back, I used the first time the Westbahn.

Despite that, the business trip was exhausting as usual. It is always a long day traveling in the early morning for a meeting in Vienna.

At least I consider it a successful business trip.

This week I finally moved some Ansible legacy playbooks to roles. It needed quite some refactoring, but at least it was finally done.

Anthropic - fresh money

This week Google announced that they will invest up to $40 billion in Anthropic: Google to invest up to $40 billion in Anthropic as search giant spreads its AI bets.

And Amazon "invested" as well. Or something like that. Because in return of the investment, Anthropic pledged $100 billion in cloud spending: Anthropic takes $5B from Amazon and pledges $100B in cloud spending in return.

Anthropic Mythos

Besides the fresh money, Anthropic model Mythos is still a hot topic:

And Firefox announced that Mythos found 271 vulnerabilities. All vulnerabilities were fixed in this week's Firefox 150 release.
