Mandelbrot in x86 assembly by Claude. Inspired by a tweet asking if Claude knew x86 assembly, I decided to run a bit of an experiment. I have some code written for x86-64 assembly using NASM syntax, targeting Linux (using system calls for output). So I fired up Claude Code (with the --dangerously-skip-permissions option) in that directory and told it what to run: It started crunching. It read ...
Researchers derive fluid mechanics equations from Newton's laws using Boltzmann's kinetic theory, resolving Hilbert's sixth problem. The proof extends previous work on Boltzmann's equation on 2D and 3D tori.
The user built a proof-of-concept for real-time bidirectional editing between a code editor and a GUI using an LSP server. They aim to create a code-based CAD system that allows using their preferred text editor, like Emacs, for a cozy development environment.
OpenAI CEO Sam Altman is defending his company against Meta's AI talent poaching, saying staying at OpenAI is the best option for building artificial general intelligence. Altman claims Meta's recruiting efforts will lead to cultural problems and that OpenAI has a superior team and culture.

Archaeologists found a Roman soldier's wrist purse in South Moravia, Czech Republic, outside the empire's traditional boundaries. The purse likely held up to 50 silver denarii, a soldier's private funds and operational expenses.
The user has created a self-improving AI factory using Claude, O3, and Sonnet models to generate and verify code, with a focus on fixing inputs rather than outputs and iterating on tasks to improve results. The factory is currently capable of shipping code but needs further development to handle more complex workflows, maximize token usage, and automate workflow management.
A data scientist & ml engineer with 8 years experience building end-to-end products. primarily worked in e-commerce before shopify ate our lunch - now working in call center tech at twilio based company in the last 5 years! looking for monthly/yearly 'no-strings' sponsorships/donations, not employment. looking to work with people that are engaged, intellectually honest,
Hi all, I’m hacking on new features for the ClickHouse native client and wanted the same “just call the model” ergonomics JavaScript and Python now enjoy. It didn’t exist for modern C++, so I wrote one. - Unified calls to OpenAI (GPT‑4o) and Anthropic (Claude 3.5) with a single C++20 API. - Streaming, multi‑turn chat, error handling—all std::optional/std::variant, no macros. - Tool calling ...
Answer (1 of 4): Yes, we do. The neurons of the central nervous system live as long as the body does, unless they are killed by accident or disease. They never divide, and are never replaced. Anybody who doesn’t suffer a catastrophic spinal injury dies with the very same nerve cells in their spin...

Swearing has a beneficial effect on pain perception and tolerance. our data replicate previous findings that repeating swear words benefits pain tolerance, extending this finding to pain threshold. the novel “swear” words showed higher ratings for emotion and humor compared with the neutral word. both made-up words were selected by... experts and laypeople briefed to choose words that could ...
A C++20 module system is introduced to replace clunky header files, allowing explicit export and import of code. Converting large packages like the finite element library is possible with non-trivial effort, reducing compile time for the converted library.
C.O.R.E is a private, portable memory system for LLMs that allows users to store and access context, facts, and preferences. It provides a dynamic, living temporal knowledge graph with full transparency and traceability.
Maze generation can be efficiently accomplished using Graph Theory and the Disjoint-Set data structure, which allows for unique maze creation every time. By applying optimizations such as union by rank and path compression, the find operation can be improved from O(n) to essentially constant time, lg* n.
The nucleus of an atom is a complex system governed by quantum mechanics, with various models such as the liquid drop model and shell model attempting to explain its behavior. The Hoyle state in carbon-12 is an excited state that can be thought of as three alpha particles orbiting each other.
