Seriously considering buying a beacon subscription because I don't want to wait until Monday to watch critical roll.

Also the cooldowns seemed legit interesting.

It's like they're doing everything right. I'm so glad for them.

Ok the discriminated unions with pydantic thing has been irking me for a while so I finally dove deep, and wrote a thing about it.

I'm sure you can do better with pydantic-internals black magic, but this gets me 90% there and is actually maintainable.

lol I found the sure fire way to plunge any SOTA cloud AI into a hallucination doom loop.

Prompt: "Please find a way to create discriminated unions in python with pydantic and abstract base classes, without having to explicitly spell out the discriminator field in the class as a 'Literal' type."

Moonshot AI claims their new Kimi Linear LLM, a hybrid with O(n) linear attention, improves quality over full attention while slashing O(n²) bottlenecks.

Huge if true. Chinese researchers are cooking 🔥🔥🔥. Have you sold your nvidia stocks yet?

Academics are debating whether to ban AI for students.

Look, universities have been unable to decide whether they function as job training or as a class signifier. The original socratic project of wandering through the fields of Academos with Athens' most curious souls isn't even on the menu.

Peter Thiel is warning us about the antichrist. Patrick Gelsinger is training some kind of Jesus AI. Curtis Yarven's Chirsto-fascism is on the rise.

I want to point out that this is not an accident. Christianity and silicon valley tech-bro cults share a lot of the same emotional inventory.

Let's play a game.

"As soon as the land of any country has all become private property, the landlords, like all other men, love to reap where they never sowed, and demand a rent even for its natural produce."

Who said it, Adam Smith or Karl Marx?

So Microsoft is pulling out of games, Win10 is EOL, their plan for desktop is like whatever, and the Phi AI model seems all but abandoned.

I wonder if they're building a rocket to mars or smth, because they certainly don't seem interested in anything on **this** planet.

Mathematics, Logic, Category Theory, and Theory of Computation comprise the modern quadrivium.

Express something mathematically ideal, logically sound, structurally universal, and computationally realizable and you have likely stripped away all incidental details and hit on something truly eternal.

How to serialize objects in the age of LLMs?

json is great but clumsy for code if humans are in the loop.

yaml is over-engineered and buggy inpython.

nestedtext is the answer.

You were going to validate inputs anyway, right?

Right?!

"We are summoning ghosts, not building animals." - Andrej Karpathy on LLMs (paraphrased).

Karpathy really gets it. Also love that he's so excited about learning Korean from a good tutor.

TIL that wikipedia has an extremely nuanced list of LLM writing tells.

So next time you want to generate slop just tell your bot to read that site and avoid it I guess.

It's so wild to me that the internet was designed with redundancy to basically have a post-apocalyptic communications network without a single point of failure, and then we kind of grafted stuff like AWS on top of it to reverse that decision.

I can't even use cloc right now to count lines of code.

So when you're having LLMs run shell commands the obvious thing is to keep polling them to judge wether the execution should keep going or takes too long. This kind of works, too.

Who would have thought the solution to the halting problem was "vibes, basically".

The other day I woke up and realized that with the server-mode in #emacs you can use emacsclient -e to have an LLM with shell access execute arbitrary elisp codein your emacs session.

And then I woke up again.

I have both vague and clear memories of handling a CD with "HoMM 2" sharpied on it at various points throughout my childhood and adolescence. Somehow, it was important.

And like most things that are truly formative, that CD's origin is conmpletely unknown to me.

Considering getting a $300 Nebula lifetime subscription because what if it's like that one dude who got an American Airlines lifetime ticket in the 70s.

He got it with a free +1, so 30 years later he was basically making a living flying around with strangers.

I don't know if we have a "worst word of the year" award or who's in charge of it but if they don't make it "vibe coding" then they're part of the problem imo.

I heard this and was like "damn this sounds like the weeknd but female".

Boom. Turns out she toured with The Weeknd during her debut.

It's the small wins.

I see a lot of posts of the "Is it just me or did Chat-GPT/Claude/Gemini/Hitlerbot get dumber all of a sudden?" variety on #ai reddits.

All cloud providers use some form of model quantization which degrades performance (measured in perplexity) provably. But not very much. Chill.

Blue sky has gotten a lot better over the last couple months.

Here is what's still missing:

- More jokes
- Spoiler tags
- Ed Greenwood posting poetry
- John Carmack posting rocket things
- Jenny Nicholson
- ok John carmack is actually on bsky but he needs to post more

So I literally just bought an #android phone after decades of being trapped in the restrictive iOS ecosystem, with the ability to freely develop third-party apps being a crucial factor in my purchasing decision.

Guess what google just announced.
