Claude reveals ECDSA curve origins

https://www.anthropic.com/_next/image?url=https%3A%2F%2Fwww-cdn.anthropic.com%2Fimages%2F4zrzovbb%2Fwebsite%2Fe4948d016f5879d721c3297b1ee1073b1e6b5734-2912x1064.png&w=3840&q=75
Researchers have solved the mystery of how NIST's widely used elliptic curve cryptography standard, ECDSA, was created. The seeds for these curves were generated by a Unix timestamp using a pseudorandom number generator from 1990s C libraries.

You could have invented transformers from memory

https://alexwang.ai/images/kea/painting.webp
The author discusses how large language models can recall obscure facts from every corner of the world, and how this ability is similar to a memory store that holds key-value pairs. The author then develops an intuitive way to look at linear maps, MLPs, and self-attention as different kinds of memory stores.

Butlerian Jihad

https://static.wikia.nocookie.net/dune/images/9/93/Original_Dune_Icon.png/revision/latest/scale-to-width-down/100?cb=20250603045629
The Butlerian Jihad was a war against conscious machines that began in 201 B.G. and ended with the destruction of all intelligent machines, but had lasting impacts on human society and technology. The war led to a ban on thinking machines, creating a gap in humanity's quality of life and driving innovation into non-thinking devices like computers and calculators.

JPEG XL vs. AVIF for web use-cases

https://jakearchibald.com/c/me-cat-Bnavw-ti.avif
AVIF generally produces smaller files than JPEG XL, but the gap narrows at maximum effort settings. AVIF is faster to encode and decode, uses less memory, and has better support for progressive rendering. However, JPEG XL can make existing JPEGs 9-20% smaller without further loss and is faster to decode at very high qualities in some browsers.

I built the RealWorld app in Lean 4

https://leangineer.com/static/blog/realworld-og.png
Lean 4 is a functional programming language used to build RealWorld, a Medium clone app. The app's behavior was written down in Lean and tested afterwards, but it does not meet the definition of correctness by construction due to missing proofs for its SQL interactions and C bindings.

A story of WiFi secrets, UART lockdowns and a damaged flash memory chip

https://adepts.of0x.cc/Eufy-Homestation2-firmware/rubber-band-setup.png
The author successfully bypassed the UART lockdown on an Eufy HomeBase 2 device, allowing them to debug key services and search for vulnerabilities. They achieved this by modifying a recovery image that was loaded into the device's flash chip, which contained a backdoored shell with root privileges.
