It’s the same pattern you see in journalism and media. The Tim Pools and Candace Owens of the world face criticism for their mistakes and grifts, and immediately drop anything resembling principles to join the movement where anything is permitted so long as you kiss the ring

Apparent NCI director candidate wants β€˜open, respectful’ post-publication peer review while promoting anonymous site that calls sleuths a β€˜mob’ Wafik S. El-Deiry Brown University physician-scientist Wafik El-Deiry has been a longtime critic of the post-publication forum PubPeer, where 75 of his papers have been flagged. For example, in an …

Unfortunately, his career should be β€˜respected’ in the same way that Ellen Langer's is respected: it’s built on confident promotion of bad studies, harassing critics via sock puppets, and never apologizing. retractionwatch.com/2025/06/10/w...

So, are you ever going to come clean about all those β€˜Science Guardians’ harassment sock puppets? Or is it just grift after grift with you?

For Mahmoud Khalll, this past year has been marked by profound hardship-and by profound courage.
A year ago, Mahmoud was walking home through our city after sharing an iftar with his wife Noor when he was detained by federal agents, flown to Louisiana, and then held in an ICE facility for months. In that time, he was forced to miss the birth of his first child. All of this for exercising his First Amendment rights in protesting the ongoing genocide in Palestine.
And yet, even in the face of that cruelty, there has also been beauty. New Yorkers raising their voices in solidarity. A city refusing to look away. Mahmoud won his freedom, and a father was finally reunited with his child.
Last night, as we marked the one year anniversary of his detention, Rama and I were honored to welcome Mahmoud, Noor, and their son Deen to Gracie Mansion to break our fast together.
Mahmoud is a New Yorker, and he belongs in New York City.

Wrote up a post collecting some thoughts. A bit rough around the edges, and I've probably butchered some of the concepts here, but there might be something valuable in the wreckage: nrposner.com/blog/afforda...

Good post! It’s got me thinking about design in terms of affordances, API surfaces, and the difference between β€˜I have this’ and β€˜I want to do this’

As long as I'm talking about programming & science:

I (re)wrote a couple posts about domain-driven design & scientific software:

A screenshot of the search term 'Kristi Noem fired', showing the 'SearchAssistant' generative AI output, claiming that while Noem has faced calls for her firing, president Trump has publicly defended her and indicated she will not be removed from her position.

Immediately below this output, multiple recent news stories from the previous half hour announce that Trump has fired Noem.

I'm currently on track to switch from Mac to Linux for my next computers, but I have successfully gotten my mother off of Windows and onto a Mac (with the LibreOffice suite to make the transfer easy). One step at a time.

The only sensible path forward is to rewrite Catholicism in Rust. I know it'll cause another schism, but the benefits of type-safety theology are too large to ignore

compiler people love to complain that users only care about syntax... but syntax is the primary affordance that users use to interact with your tool! of course it's massively important what that syntax is!

I haven't gone whole hog on agents yet, but did get a lot of help writing macros to make the code less repetitive. Almost all the functions are identical!

crates.io: Rust Package Registry

I was recently going down the MacOS performance rabbit hole, wound up publishing some Rust bindings for the Accelerate framework's vectorized math functions: crates.io/crates/vforce

If any of your applications benefit from vectorized math, might be useful!
