The gaslighting here is astonishing. Acting President @ClaireShipman should speak for herself. As a @Columbia faculty member I do not share her values of authoritarian university governance and enforcement of ideological conformity, all to advance a racist Trump admin agenda.
Acting University President Claire Shipman, CC ’86, SIPA ’94, described Columbia’s Wednesday agreement with President Donald Trump’s administration to pay $220 million to restore funding as “in line with our values” in her first interview with Spectator. l8r.it/agLK

I am sad to hear of the passing of Dimitri Bertsekas. This one hurts. Dimitri had a big effect on my career, from inspiring research topics to writing one of my tenure letters. A long thread on memories of Bertsekas and some of his works that influenced me the most.

Dimitri was both a giant and a kind man. Sad day today.
We've lost an absolute giant today. RIP Dimitri Bertsekas. His probability and optimization books got me through my masters. Massive loss for the MIT community and the field.

The leadership at @Columbia seek to discipline a student for ... criticizing the trustees. So much for academic freedom and open discourse. The fish rots from the head down.
Having cut a horrible deal with Trump giving him oversight of the university, @Columbia may be the worst campus in the United States for free speech, especially about Israel. It is threatening to discipline a student for distributing this legitimate flyer. trib.al/quwTJcC

Sharif is the #1 university in Iran. Over the last 25 years, it has been in the top 3 destinations of top Olympiad medalists.

What do the smartest kids in the world do when they grow up? I did the largest study of ~18,000 International Olympiad medalists (IMO, IOI and IPhO) over the last 25yrs, arguably the sharpest analytical minds of the world in high school, to see where they ended up and traced ~50% of them. Founders of ~20 unicorns and ~7 decacorns and ~10 billionaires: OpenAI, Cursor, Stripe, Databricks, Perplexity, Ethereum, Cognition, Hyperliquid, Fireworks, Modal, Quora, Parallel, Cartesia, Wispr Most kids went to MIT, a whopping 12% of them, followed by Cambridge (7%) and Sharif (3%)! The career paths they chose (of those who graduated) were: — 36% Academia (professors) — 26% Other — 22% in Software / Tech — 12% in Quant / Finance — 5% Founders! The biggest employer was Google, by far, at 6%. Others interesting tidbits were: — 47 of them work at Jane Street (#3) — 38 at OpenAI (#5) — 15 at Anthropic — 8 at Cognition — 6 at Isomorphic Labs Olympiaders were 1500x more likely to be billionaires and 4000x more likely to be unicorn founders than the average person!

Ken Griffin pays only 0.22% of the market value of his $240M condo in property tax, whereas condos in the lowest 10th percentile (<$350K) pay almost 1.4%.
Exclusive: Billionaire Ken Griffin is appalled that Mayor Zohran Mamdani used his 24,000-square-foot Manhattan penthouse last week as the backdrop for a tax-the-rich video, and that has triggered a subtle threat of re-evaluating investment in the city. on.wsj.com/495DhvH

Sharif University of Technology (founded as Arya Mehr University in 1966) is an icon of modernization and progress in Iran. Its alumni include the first woman to win the Field Medal in Mathematics, Maryam Mirzakhani. It has been a national symbol of achievement, gaining international recognition for the quality of its graduates, large number who have been admitted into the very best engineering programs in the West. The aim of this kind of wonton destruction could only be the nation of Iran itself.

Oh man, who knows where this will lead, but at the least we may get to read some VERY interesting emails from and to Columbia's oligarchic trustees and admins: Court Finds Columbia May Have Acted as Government’s Instrument to Suppress Palestinian Advocacy cair-ny.org/news/3/19/26-bre…

🚨 NEW: Over the past year, Columbia University has played a direct role in the arrests and targeting of its international students by federal immigration agents, in violation of the university's own stated policies and protocols. What began last March has continued since — Mahmoud Khalil, Mohsen Mahdawi, Ranjani Srinivasan, Yunseo Chung, Elmina Aghayeva...

counterpoint: advertising fake prices with no intention of execution is market manipulation, and doesn't have a place in a healthy market structure
unbelievable to have to spell it out, but: - a "fresh quote" is an oxymoron - eth shipped slippage protection a decade ago - "pamms" aren't amms, they're trading strats - traders tightening/widening spreads for any reason is legitimate, rational behavior - markets punish altruism

Told this to the New York Times today and will not stop saying it. Iranian Americans who oppose their homeland being bombed deserve to be heard right now. Bombing elementary schools and killing schoolgirls doesn’t bring freedom and democracy to anyone.

This ruling against Columbia University is a victory for free speech, and all the values that underlie the academy.
BREAKING: In a major victory for pro-Palestine student protesters at Columbia University, a judge in New York on Friday dismissed the university's findings of several disciplinary violations against 22 students who had been arrested over the occupation of Hamilton Hall in April 2024. The protesters had occupied the Columbia building and renamed it Hind's Hall, in honor of Hind Rajab, a Palestinian child who had been killed by Israel earlier that year. New York Supreme Court judge Gerald Lebovits noted that Columbia's internal panel's determinations that the student protesters committed most of the charged disciplinary violations are "arbitrary and capricious". "...the evidence before the panel still did not show by a preponderance that petitioners committed disciplinary violations other than being in Hamilton Hall during the 22 hours that it was occupied," the judge noted. Here's the operative part of the court order below.
