Our mono repo's type linting went from 94s to 4s switching pyright -> ty, and we caught a few extra issues! 🤗 @astral_sh @charliermarsh.

I want to be a delveologist when I grow up. My goal this weekend is to use the term "delveology" 10 times in conversation.

.@cursor_ai Bugbot is fantastic. The Claude Code Action is too verbose. It will write a whole essay even when all it has to say is "lgtm". And Github Copilot is very rudimentary. But Cursor Bugbot comments are always worth reading, and ~50% are worth fixing.

GitHub is one of my favorite developer tools. It's fantastic, and it's better than most of the analogous tools at most big techs. Most impressively, GitHub has continued to improve through 2 CEOs (@natfriedman @ashtom) under Microsoft. Keep it up!

I like GPT5. And I like having only three buttons: 5, Thinking, and Pro.

Weapons. 10/10 must see. What is the message? I'd like to think it's something about the Boomers sucking the life force out of the young. Sinners, Weapons, and 28 Years Later are all phenomenal. Is 2025 the best year for horror in my life? The pandy generation has smelled

Friend had gut issues for years. Stopped taking AG1. Gut issues miraculously and completely went away. There's 100 ingredients in it, no specified amounts, and no evidence for it. Shame on @davidasinclair and @hubermanlab for shilling AG1.

Notice he's muting the voice model every time he wants it to respond. This is the biggest hurdle for using the voice models seamlessly. Imagine needing to plug a human's ears every time you want them to respond.

The irony of this language learning demo is that learning languages has never been less important. chatGPT Voice and Google Translate and o3 for image translation erased language barriers on a recent trip to Japan. It's also unfortunate GPT5 didn't use whisper for text2speech.

Tonight's party discussion:.Suppose we have a Turing complete 1D Game of Life. And suppose suffering occurs somewhere in the evolution of that cellular automata. Would we be able to recognize it as suffering, and when does that suffering occur?.Bonus: Is inference on a model with.

From the Kill List podcast I realize two things:. 1) Like the medical system, our law enforcement isn’t a preventative system, it’s a reactive system. Only interested after tragedy has already happened. 2) The people who have people in their lives who would put a hit out on.

Should the human race endure?. I’d love to have a conversation with Thiel on all the ways the answer to that should be “no.” For example, as Thiel mentioned earlier in this interview, transhumanism. More human than human.

I absolutely love Sarah Paine's requirement to give not only one's thesis, but also a counter-argument to it. Prevent mono-causal explanations.

First Sarah Paine lecture & interview is out!. How Imperial Japan (population 47M) crushed Tsarist Russia (130M) and Qing China (400M). For me, the most interesting thing was that Japan's surprise attack on Port Arthur at the beginning of the Russo-Japanese War (1904) helps us
