My thoughts on the IACR election issue (since many have asked privately):
- This was an honest accident, and Moti Yung deserves being cut some slack. Yes, it’s a silly mistake, but mistakes happen.
- The IACR board reacted excellently and scheduled timely follow up elections.

Sometimes you just have to admit that you wouldn't be any good at running a successful tradwife channel. Smells heavenly though.

He's the Pied Piper? He's going to rid New York of rats and then refuse to pay himself?
the fash talking heads are aligning their talking points on Zohran, arguing that... downwardly mobile people are more likely to support left policy... (gasp) I'm not sure where they could have gotten this idea. It's almost like Z ran on affordability

In the Taunus mountains north of Frankfurt we celebrated Laubmännchen on Whit Monday. One of the kids would dress up as the spring and the other would pull it through town in a handcart decorated with fresh leaves. We would then demand eggs and bacon at every house.

TIL that while we managed to agree with the Brits on a *date* to change the clocks, we apparently couldn't agree on a time. 🤦♂️ Timezones are truly cursed and DST even more so.

I'm a bit confused where anyone got the idea that Germany had any kind of principled position on this.
We are alarmed by reports that Germany is on the verge of a catastrophic about-face, reversing its longstanding and principled opposition to the EU’s Chat Control proposal which, if passed, could spell the end of the right to privacy in Europe. signal.org/blog/pdfs/ge...

An MRI is an interesting combination of plasticky Star Trek esthetics and the soundscape of a construction site. Also takes a lot longer than I expected.
