If Putin were running the White House directly, what would he do differently?

The ability of demagogues & autocrats to surprise, to create a new scandal every day, is their superpower. It diminishes attention to the previous day's transgressions & normalizes them. It slowly numbs the senses, including outrage. Values are the only defense. Hold them dear.

[Garry Kasparov @Kasparov63]

The point of modern propaganda isn't only to misinform or push an agenda. It is to exhaust your critical thinking, to annihilate truth.

Not much to say except that Oct 8th in America changed my worldview more than Oct 7th in Israel. 🎗️

Balance is a false god. Treating a fact and a lie as equal is not balance but malpractice. It favors the liar. The press is protected in this country so it can protect democracy. That's also your job as you moderate tonight.

@MichaelAArouet Serial killer types were given access to automatic weapons, and now they can kill in parallel.

Whatever your feelings about the Trump shooting, it’s worth pointing out that if a Secret Service team can’t protect a presidential candidate, maybe expecting Mrs. Krabappel to protect her 4th grade students from an active shooter is unrealistic.

Political violence is an assault on democracy itself and must be condemned without conditions. It represents a loosening of the social contract and unleashes the worst elements. Attempts to rationalize or score points fan the flames. Beware of those who try.

If there's one thing to understand with Russia, unless there's true consequences to their terrible actions, you can be sure they'll do it again and again, and get worse and worse.

in the last 10 days the Supreme Court has ruled that the president can do crimes, bribery is legal, agencies have no actual authority, and also that the homeless can be thrown in prison for the crime of not having a home.

@BobbyHugh @danshipper 💯. I bet FamilySearch/LDS has a huge backlog of scanned historical records that could benefit from this.

Reading a tweet is a bit like downloading an (attacker-controlled) executable that you instantly run on your brain. Each one elicits emotions, suggests knowledge, nudges world-view.

In the future it might feel surprising that we allowed direct, untrusted information to brain.

Introducing Sora, our text-to-video model.

Sora can create videos of up to 60 seconds featuring highly detailed scenes, complex camera motion, and multiple characters with vibrant emotions.

Prompt: “Beautiful, snowy Tokyo city is bustling. The camera moves through the bustling city street, following several people enjoying the beautiful snowy weather and shopping at nearby stalls. Gorgeous sakura petals are flying through the wind along with snowflakes.”

Ten months ago, we launched the Vesuvius Challenge to solve the ancient problem of the Herculaneum Papyri, a library of scrolls that were flash-fried by the eruption of Mount Vesuvius in 79 AD.

Today we are overjoyed to announce that our crazy project has succeeded. After 2000 years, we can finally read the scrolls:
This image was produced by @Youssef_M_Nader, @LukeFarritor, and @JuliSchillij, who have now won the Vesuvius Challenge Grand Prize of $700,000. Congratulations!!

These fifteen columns come from the very end of the first scroll we have been able to read and contain new text from the ancient world that has never been seen before. The author – probably Epicurean philosopher Philodemus – writes here about music, food, and how to enjoy life's pleasures. In the closing section, he throws shade at unnamed ideological adversaries – perhaps the stoics? – who "have nothing to say about pleasure, either in general or in particular."

This year, the Vesuvius Challenge continues. The text that we revealed so far represents just 5% of one scroll.

In 2024, our goal is to from reading a few passages of text to entire scrolls, and we're announcing a new $100,000 grand prize for the first team that is able to read at least 90% of all four scrolls that we have scanned.

The scrolls stored in Naples that remain to be read represent more than 16 megabytes of ancient text. But the villa where the scrolls were found was only partially excavated, and scholars tell us that there may be thousands more scrolls underground. Our hope is that the success of the Vesuvius Challenge catalyzes the excavation of the villa, that the main library is discovered, and that whatever we find there rewrites history and inspires all of us.

It's been a great joy to work on this strange and amazing project. Thanks to Brent Seales for laying the foundation for this work over so many years, thanks to the friends and Twitter users whose donations powered our effort, and thanks to the many contestants whose contributions have made the Vesuvius Challenge successful!

🎉 The best way to start the week is to find out that our MedSAM is finally published today in Nature Communications!

**Segment anything in medical images**
Paper: https://t.co/3LJIZcxyk1
arXiv: https://t.co/YmbbM10iKV
Data & Code: https://t.co/7PFupAxo1K

MedSAM is the first promotable foundation model for medical image segmentation.

**Highlights**:
⭐ Before its formal publication, we have received 220 citations and 1400+ GitHub stars 🙏🙏❤️‍🔥❤️‍🔥❤️‍🔥
📊 We curated a large-scale medical image dataset with 1,570,263 image-mask pairs, covering 10 imaging modalities and over 30 cancer types.
🚀 Built on top of SAM (@AIatMeta ) with transfer learning, we have significantly enhanced its segmentation performance of medical images.
📈 Comprehensive evaluations of 86 internal validation tasks and 60 external validation tasks demonstrate its better accuracy and robustness than modality-wise specialist models.

**What is Next? --- Clinical Translation!!**
🍕Our next goal is to make the model deployable on laptops (CPUs) or other edge devices without reliance on GPUs. We have distilled a lightweight model, LiteMedSAM, offering a speed boost of 10x while maintaining accuracy. Plus, we have integrated it into the 3D Slicer plugin, providing an efficient tool for medical image segmentation.

🌐 To further promote developments in this field, we organize a competition on @CVPR: Segment Anything in Medical Images on Laptop! An out-of-the-box baseline has been released to reduce the entry barriers. Welcome to join us to push the boundary further: https://t.co/xDsp7zwoa1

🙏 Massive thanks to MetaAI @AIatMeta for their open-source project SAM and many reviewers/users for their invaluable feedback.

A huge shoutout to my postdoc Jun Ma (@JunMa_11) for his leadership on this project!!
