How I vibe coded using Claude for Teachers to visualize how the proposed Sunshine Protection Act would affect morning prayers and Friday afternoon candle lighting times. @josh_schlenger @ShaisTaub

Somehow I get the feeling Iran wants to be in a constant state of war because if they wouldn’t be, they would have to worry once again about their people rising up against tyranny. I worry about our US forces and my brothers and sisters in Israel.

@GilStudent I once heard him give shiur. I was too young to really understand his rich rabbinic Hebrew. I could not tell when he his reading of Rav Akiva Eiger had stopped and his own comments had begun.

@GilStudent I fondly remember watching Rav Dovid Lifschitz daven during the final years of his life when I was still in the high school at MTA and then an early admissions freshmen at Yeshiva. His face glowed in my mind like a Malach.

@ZachEFish The Chazon Ish makes a similar argument about the Meiri which had been inaccessible to Jewish learning for centuries. He held while we can certainly learn Meiri, it could not be used for psak since Hashgacha was involved in what Seforim would become available for our Mesorah.

Hot take: this isn’t a bad thing at all. Here’s why: The harder something is to produce, the more its mere existence tells you about its value. Before the printing press, creating a book meant paying someone to copy every single word by hand. And even if a work was copied just a few times that alone was a pretty strong sign that people thought it was very valuable and worth preserving. But once books became easy to produce and reproduce, the fact that something exists stopped telling you very much. What tells you something is whether people keep printing it and passing it on. So if a relatively modern book has dwindled down to one unwanted copy - that tells us It likely had very little value. Not only that, it seems obvious to me what Anthropic is doing might be the only chance the information in these texts have any chance of being persisted in any form. You could even argue that preserving every single physical book forever does future generations a disservice. Survival itself used to act as a filter. It helped show us what people considered valuable enough to keep and pass down.If we preserve absolutely everything, that signal disappears. I don’t have too much conviction on the last point, maybe it would be cool to have some archive for random books, but definitely don’t get why there is so much uproar like this is a crime against humanity.

🦔AI companies are bulk-buying rare books, scanning them through high-speed machines that cut the spines off, and shredding the originals. A service called ISBNdb facilitates orders of up to a million books and keeps buyers anonymous. Pre-2022 books are premium because they're free of AI-generated text. A federal judge ruled the practice is fair use because eliminating the original means only one copy exists at a time. Anthropic hired the former head of Google Books partnerships to obtain "all the books in the world." My Take This got to me. A bookseller told 404 Media that rare books with almost no surviving copies are being fed into this pipeline. Books that survived wars, fires, and centuries of handling are being shredded so an AI can learn to write a better marketing email. ISBNdb's website literally says "'AI company destroys two million books' is not a headline that generates sympathy," and they still built an entire business around making it happen quietly. They offer NDAs as a feature. They coach clients to call it "digital preservation." I've covered AI companies scraping the internet, torrenting libraries, and stealing music. This is worse because it's irreversible. You can re-upload a website. You can reprint a bestseller. You can't replace the last three copies of an 18th-century botanical text once someone shreds them for training data. And the judge said it's legal. So it's going to accelerate. "We shred rare books and offer NDAs so nobody finds out" is a legitimate business model in 2026. What a timeline. Hedgie🤗

@GilStudent And my rebbe, Rav Parnes gave a Mussar schmooze on the value of Temidius consistency after Cal Ripken broke Lou Gehrig’s record for consecutive games played. As a Yeshiva high school rebbe professional sports is often the best Mussar.

@GilStudent They are not role models but inspiring examples of people using every fiber of their being to accomplish a goal. Rav Aharon Lichtenstein hung the newspaper clipping of Michael Jordan’s flu game outside the Gush Beis for inspiration.

Mayor Zohran Kwame Mamdani
At our five-borough municipal grocery stores, New Yorkers will get a 30% discount on eggs, milk, chicken, fresh produce and other everyday essentials. In the wealthiest city in the richest country in the world, no one should have to wonder how they’ll afford the food they need to feed themselves or their families.

In the Code of Jewish Law, R. Moshe Iserles writes that one who is perceived as an enemy (or a “hater”, ‘sonei’) should not visit an ill person or a mourner (YD 335:2). It will look to the public, and to the grieving individual himself, as if that person is gloating and it will increase their suffering. It has long been understood that certain individuals, by their presence, bring anguish to those who are already suffering. Decency requires that they focus on the victims and not on themselves.

Mamdani: Today, I am proud to announce a collection of essential staples that will be predictably 30% cheaper at all five of our city-run grocery stores. This core set of goods will include all fresh produce, meat, and seafood, along with 20 other essential items like cheese, milk, and bread. Here's how it will work. Once a month, our five city-run grocery stores will set prices for this core set of goods at 30% below typical retail prices. No exceptions, no gimmicks. The savings will last for the entire month. That means no weekly fluctuations or sticker shock at the checkout line—not for our seniors living on fixed incomes, nor for the parents who rely on a regular supply of apple slices to keep toddler tantrums at bay.

Me explaining the Talmud to Zoomers: “Well, it’s basically a Discord log from 1,800 years ago. Then another Discord log from about 1,500 years ago arguing over every message in the first one. Then a guy about 1,000 years ago writes the most legendary blog post explaining both. Oh, and there are also Slack logs from 1,800 years ago… and that’s how we figure out how to light the Hanukkah candles.”
