From a startup CTO: "Over the break, I realized how good these models have gotten. This year we'll be using them ~10x more vs last year. So my first order of business: I want to find a solution to measure our *current* dev productivity so I have a baseline to compare to, later."

Many recent posts on free energy. Here is a summary from my class “Statistical mechanics of learning and computation” on the many relations between free energy, KL divergence, large deviation theory, entropy, Boltzmann distribution, cumulants, Legendre duality, saddle points, fluctuation-response…

A horrible story but god bless this woman so accurately reading the ICE goons for filth here

One of the happiest updates I’ve written since I started following this story. 12 students back in status and maybe more to come. Across the country, students are saying their SEVIS is back. www.dailycal.org/news/campus/...

“The wife of Kilmar Abrego Garcia, who was mistakenly deported to El Salvador by the Trump administration, was forced to move to a safe house with her children after the government **posted their home address** to social media.” 4/23/25 newrepublic.com/post/194289/...

As part of their plan to GUT the science mission at NASA, Trump and Musk want to cancel the Nancy Grace Roman Space Telescope — a critical project that is on time, under budget, and nearly finished. They want to flush those taxpayer dollars down the drain. How is THAT efficient?

Under the Trump administration’s theory of the law, the government could have banished this U.S. citizen to a Salvadoran prison then refused to do anything to bring him back. This is why the Constitution guarantees due process to all. Could it be more obvious? news.azpm.org/p/news-artic...

A reminder that NSF is explicitly breaking the law if/when they attempt to cancel grants that focus on promoting participation in science by underrepresented groups on that basis, incl women in science programs like NSF ADVANCE. Congress expressly directs the NSF to grant funds for this purpose. 🧪

Can confirm that my NSF grant "How False Beliefs Form & How to Correct Them" was cancelled today because it is "not in alignment with current NSF priorities" Shocking that understanding how people are misled by false information is now a forbidden topic. Our work will continue but at a smaller scale

🧵 THREAD: A federal whistleblower just dropped one of the most disturbing cybersecurity disclosures I’ve ever read. He's saying DOGE came in, data went out, and Russians started attempting logins with new valid DOGE passwords Media's coverage wasn't detailed enough so I dug into his testimony:

Mr. Abrego Garcia was illegally abducted by the Trump Admin and, by their own admission, wrongly deported to El Salvador. He shouldn’t have to spend another second away from his family. I'm flying to El Salvador tomorrow morning to check on his condition and discuss his return.

I said my main goal of this trip was to meet with Kilmar. Tonight I had that chance. I have called his wife, Jennifer, to pass along his message of love. I look forward to providing a full update upon my return.

𝗧𝘄𝗼 immigration attorneys in Massachusetts, both US citizens, received the same letter telling them to self-deport. www.nbcboston.com/news/local/2...

The Department of Homeland Security sent a letter to Dr. Lisa Anderson, who was born in Connecticut, which stated: “It is time for you to leave the United States." Anderson has been carrying her U.S. passport on her at all times since receiving the email and is seeking an immigration attorney.

First it was illegal immigrants, then green card holders, and now it's US citizens. This is slippery slope that is only going to get more slippery. **All in less than 3 months.** It's going to get much worse unless we apply pressure to protect democracy. www.nbcboston.com/news/politic...

Rubio’s defense of the arrests/deportations of student protesters relies almost entirely on cases decided before the Supreme Court gave meaning to the First Amendment. Harisiades was decided before Brandenburg. Turner was decided fifteen years before Abrams! knightcolumbia.org/documents/ns...

I'm particularly excited about these new multi-modal models: huggingface.co/collections/...

Steve Kerr wore a Harvard basketball shirt after the Warriors’ win tonight: “Yes, this is me supporting Harvard. Way to go. Way to stand up to the bully.”

Let’s be clear. When the President defies the Supreme Court, it is the role of Congress to remove him from office. Full stop.

DOGE is a criminal conspiracy to defraud the people of the United States

AOC: We saw Majorie Taylor Greene buy that dip. How much did you make? How much did you make off of people’s despair? How much did you make off of that panic? How much did you make off of that suffering? No more. We can’t accept it

Good morning. It is now 12:01 AM, meaning the largest tariff hike in US history has gone into effect There's now another 10-40% tariff on imports from most nations & another 74% tariff on China ~3/4 of imports are now hit by tariffs, and the average US tariff rate is up to ~30%

As markets melt down around the world, Congress could act right now to prevent an economic collapse before markets open on Monday. The only thing standing in the way is a few spineless Republicans.

Almost all NOAA Research websites that rely on cloud services - including Amazon, Google and WordPress - are poised to disappear at midnight ET Saturday after a contract was targeted for "early termination." Labs may also feel the effects. Story for @bloomberg.com (free link):

After 24 hours on his feet, Cory Booker is defending the scientific research establishment of this country - calling out an experience like the one that drives me and SO MANY of my fellow scientists to do the work we do - that maybe we can do for others what we couldn't for our own loved ones.

You’ve probably heard about how AI/LLMs can solve Math Olympiad problems ( deepmind.google/discover/blo... ). So naturally, some people put it to the test — hours after the 2025 US Math Olympiad problems were released. The result: They all sucked!

The president is not a king. The Constitution could not be clearer: No person shall be elected to the office of the President more than twice. Donald Trump would rather fantasize about a fictional third term than do anything to lower costs for working families.

I signed. Please consider signing.

DOGE preferentially cancelled grants and contracts to recipients in counties that voted for Harris. No matter where you stand on the political spectrum, this is a wild finding. Source: buff.ly/2vBLXx2
