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.
Columbia Daily Spectator@ColumbiaSpec

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

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.
Kenneth Roth@KenRoth

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!

Hadn’t been following the @ZohranKMamdani second home (“pied-à-terre”) tax closely until this @TheEconomist article reviewed it. The conditions under which the tax would apply are smartly written to target only the uber rich who own a second home in NYC (1) worth more than $5M (2) whose owners are not tax residents and (3) do not rent them out. Yet the neoliberal rag maintains the tax “could do real harm,” citing a billionaire (and non-economist) who speculates it could cost the city jobs. Get a fricking grip. There is no nexus between the tax and job creation. On the benefit side, the tax would “nudge some absentee owners to sell to New Yorkers who might make greater use of them,” as the story admits. And the tax would raise $500M per year in revenues. Seems like a no brainer and easily passes a cost-benefit test. Go get em!

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%.
The Wall Street Journal@WSJ

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.

@TheSpeculator0 this is the way kalshi charges also. this is because the fee per contract should be symmetric between p and 1-p, there is no difference between buying a YES at price p and selling a NO at price 1-p.

Polymarket enabled fees today for more markets and it's yet again another complete shitshow: previously it was already live on crypto markets with the following formula: fee per contract = p × feeRate × (p × (1 - p))^exponent This means that the fee is a parabola around 50c in terms of how much you pay as % of your premium. somewhat reasonable. Today, they, without telling anyone, removed the first p term in the formula, so it just becomes: fee per contract = feeRate × (p × (1 - p))^exponent Now fee in dollars is a parabola, but fee as a % of premium has an extreme inverse relationship to price. If you spend 100 dollars on a contract with a 0.1c price, you will pay 30 dollars in fees in e.g. the economics category. Insane tax on small bets and this is going to reduce turnover a lot of people who want to get out of near 1/0 positions (the same is true of markets trading at e.g. 99.9 from an EV perspective)

🚨 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...

@burckmeister @vitorpy @deanmlittle spoofing may be optimal for the individual, but not the system, e.g., prisoner's dilemma. if these shenanigans persist users will eventually abandon solana defi.

counterpoint: advertising fake prices with no intention of execution is market manipulation, and doesn't have a place in a healthy market structure
Dean 利迪恩 (⚛️,🐱) | sbpf/acc@deanmlittle

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.
Meghnad Bose@MeghnadBose93

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.
