Anthropic accidentally leaked their entire source code yesterday. What happened next is one of the most insane stories in tech history. > Anthropic pushed a software update for Claude Code at 4AM. > A debugging file was accidentally bundled inside it. > That file contained 512,000 lines of their proprietary source code. > A researcher named Chaofan Shou spotted it within minutes and posted the download link on X. > 21 million people have seen the thread. > The entire codebase was downloaded, copied and mirrored across GitHub before Anthropic's team had even woken up. > Anthropic pulled the package and started firing DMCA takedowns at every repo hosting it. > That's when a Korean developer named Sigrid Jin woke up at 4AM to his phone blowing up. > He is the most active Claude Code user in the world with the Wall Street Journal reporting he personally used 25 billion tokens last year. > His girlfriend was worried he'd get sued just for having the code on his machine. > So he did what any engineer would do. > He rewrote the entire thing in Python from scratch before sunrise. > Called it claw-code and Pushed it to GitHub. > A Python rewrite is a new creative work. DMCA can't touch it. > The repo hit 30,000 stars faster than any repository in GitHub history. > He wasn't satisfied. He started rewriting it again in Rust. > It now has 49,000 stars and 56,000 forks. > Someone mirrored the original to a decentralised platform with one message, "will never be taken down." > The code is now permanent. Anthropic cannot get it back. Anthropic built a system called Undercover Mode specifically to stop Claude from leaking internal secrets. Then they leaked their own source code themselves. You cannot make this up.

@Jonathan_Blow Couldn’t join live from Japan Time 🥱 will it be in Twitch or YouTube afterwards?

As someone who programs game ("simulation") engines, I have a long-term project where I want to explain why the "simulation hypothesis" is nonsense in like 5 different ways (while pointing toward what a sensical version would look like).
So this Saturday at 10am Mountain Time, I will do a livestream that is the first in the series of Simulation Saturdays. To start with, I just want to lay out the framework in a not-organized, random-discussion kind of way, to just make an outline of what all the relevant topics would be. Then on later Saturdays we can go to various subtopics and talk about them.
(Unlike #screenshotsaturday, the first Simulation Saturday will be at a time that is widely recognized as Saturday by many people, though I make no promises about subsequent Simulation Saturdays.)

@LubaRaphael @Abdulla85594595 Library designers and writers. Cf. C++ standards committee is divided into language and library.
With this I am not saying it is right, though 😅
How do you provide type-traits functionality in jai?
Looking forward to the beta becoming more accessible!
English
@Abdulla85594595 It looks like this is code from the STL. What would you call the people who design and implement the STL?
English
Can you imagine that someone typed these lines and was like "Yup, this looks fine. Another job well done!"?

@rfleury I’ve been trying to debug a class with
- publics: 4 strings, 7 ints, a bool and 1 enum
aaand
- privates: 10 atomic bools, 1 atomic uint32, a thread, 3 pointers, a unique pointer, 3 vectors, a chrono time point, a gstreamer pipeline wrapper, a bool,

Tangent going from gcc on Linux over here to clang & llvm on os x over there
Which one, if any, is standard-compliant?
Or maybe a compiler bug in some standard library implementation?
Monostate?! 🤯

@undebeha Is the remaster already out? 😄 I now I am late to find the thread!
Otherwise, is the video of 3blue1brown representing attention good for this description?
English
this could really use some data flow diagrams. alas im not ambitious enough to present any rn. when i remaster this thread i'll add some diagrams

i've been trying to understand the transformer architecture for ages but it never clicked. so recently i started trying to learn its history and that has helped a LOT. to try to cement what i learned imma write up a essay.

Creating a story that is easy to follow reviewing the commits chronologically.
English
1.2. Suggest the reviewers approaching the review by reading the changes commit-by-commit rather than starting with the complete set of changes.
Example: github.com/github/codeql/…

Distillation can be legitimate: AI labs use it to create smaller, cheaper models for their customers.
But foreign labs that illicitly distill American models can remove safeguards, feeding model capabilities into their own military, intelligence, and surveillance systems.
English
We’ve identified industrial-scale distillation attacks on our models by DeepSeek, Moonshot AI, and MiniMax.
These labs created over 24,000 fraudulent accounts and generated over 16 million exchanges with Claude, extracting its capabilities to train and improve their own models.

@Jonathan_Blow I learned and liked differential geometry from the MCMC handbook, chapter on Hamiltonian by Radford Neal.

I am giving up on this book after 50 of 200 pages. What should I read instead?

@mfranz_on @AstraKernel C/C++ isn’t/aren’t (a) language/s.
Are runtime performance and low level the same?
English
@AstraKernel ya I am just pointing out that rust was not mentioned, only C/C++ for low level
English
Python is something special and Rust was not mentioned, only C and C++. Perfect.
