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.

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. https://t.co/zmmLlcc1Bs

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

@HalSinger @ZohranKMamdani @TheEconomist moreover the apartments like Ken Griffin's are extremely advantageously taxed currently

[ciamac moallemi @ciamac]

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. https://t.co/omvtf8cDBi

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.

[James Schamus @JamesSchamus]

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 https://t.co/5NfxIBlBtc

[Meghnad Bose @MeghnadBose93]

🚨 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.

[ciamac moallemi @ciamac]

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

[ciamac moallemi @ciamac]

@ediyork @JonAguiar what are examples of financial exchanges that do this?

[ciamac moallemi @ciamac]

@vitorpy @deanmlittle i can see the incentive to do it if others do it. but collectively it’s a abusive market structure. these pamms should be blacklisted by routers.

[Etan Mabourakh @etanmab]

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.

[Rob Howse @howserob]

This ruling against Columbia University is a victory for free speech, and all the values that underlie the academy.
