The name Kseniia is the Russian version of Greek Xenia, meaning "hospitality to foreigners". According to the tradition of xenia, anyone who harmed a resident foreigner would be cursed by Zeus Xenios ("Zeus protector-of-foreigners") https: //en.wikipedia.org/wiki/Xenia_(Greek)
Harvard Researcher Kseniia Petrova has been detained when returning to the U.S. on February 16, 2025. She had frog embryos and she didn’t properly declare them. Border agents decided this warranted taking away her J-1 visa and deporting her. 🧵Petrova was arrested in Russia

Thanks to everyone who chimed in with criticism of my recent POSIWID post. If I understand you all correctly, you think that Stafford Beer had good intentions when he invented the phrase, and that's more important than how it gets misused in real life. Enlightening!

ME, REPEATEDLY, OVER THE PAST SIX MONTHS: Daniel! Publish already! Your predictions keep coming true before anyone even sees them! DANIEL: Oh, that one wasn't even a real prediction, everyone knew that would happen.
I read this and thought it was silly that one of the key assumptions was that CoT wouldn't be faithful. not 4 hours ago, a prediction from this paper was proven right by Anthropic: CoT is not, in fact, truthful most of the time. everyone must read this.

You don't know the half of it - he grilled us for *eight hours* on every little detail, then published the highlights. By the end I felt like I had run a marathon (and he was still as chipper as always).
@DKokotajlo @slatestarcodex Dwarkesh podcast is super good, gives nuance sense of everything!!

People had lots of questions about my drowning child tweet yesterday - eg do I believe in infinite moral obligation? Rather than try to answer piecemeal, I'll just give my whole theory of morality and charity here so you can criticize it or let me know if it has unexpected

I went on a walk and saw a child drowning in the river. I was going to jump in and save him, when someone reminded me that I should care about family members more than strangers. So I continued on my way and let him drown.

The Irish flag is green, white, and orange - green for the southern Catholics, orange for the northern Protestants, and white for the dream of peace between them. Relatedly, the US flag is red, white, and blue, and I think that's beautiful.
