Magika: AI powered fast and efficient file type identification
Today we are open-sourcing Magika, Google’s AI-powered file-type identification system, to help others accurately detect binary and textual file types. Under the hood, Magika employs a custom, highly optimized deep-learning model, enabling precise file identification within milliseconds, even when running on a CPU. Magika command line tool used to recognize a identify the type of […]
Video generation models as world simulators
This technical report focuses on (1) our method for turning visual data of all types into a unified representation that enables large-scale training of generative models, and (2) qualitative evaluation of Sora’s capabilities and limitations. Model and implementation details are not included in this report. Much prior work has studied generative modeling of video data […]
It Was 33 Years Ago Today: Happy Birthday Lemmings
Today, February 14th, 2024, marks the 33rd anniversary of Lemmings, the game that transcended mere entertainment to become a cultural icon and a catalyst for Scotland’s thriving game development industry.

Show HN: Galactic Compass – an app that points to the galactic center
Hey I made an app! It’s a green floating arrow that always points to the middle of the Milky Way. i.e. 26,000 light years towards the supermassive central black hole, Sagittarius A*. You can have it too! Download Galactic Compass from the App Store. BUT: I don’t know how to write apps. And yet here […]
Passing stars changed the orbits of planets in the solar system
The orbit of Earth around the Sun is always changing. It doesn’t change significantly from year to year, but over time the gravitational tugs of the Moon and other planets cause Earth’s orbit to vary. This migration affects Earth’s climate. For example, the gradual shift of Earth’s orbit and the changing tilt of Earth’s axis […]

Building an LLM from Scratch: Automatic Differentiation
Setup from typing import Any, Optional, List import networkx as nx LLM from scratch: Automatic Differentiation I’m building a modern language model with all the bells and whistles completely from scratch: from vanilla python to functional coding assistant. Borrowing (shamelessly stealing) from computer games, I’ve built a tech tree of everything that I think I’ll […]
Uv: Python packaging in Rust
TL;DR: uv is an extremely fast Python package installer and resolver, written in Rust, and designed as a drop-in replacement for pip and pip-tools workflows. uv represents a milestone in our pursuit of a “Cargo for Python”: a comprehensive Python project and package manager that’s fast, reliable, and easy to use. As part of this […]
Safe and reliable production changes; and how Rivian recently got this wrong
Changing production infrastructure can be scary because we don’t want to break things for customers, mistakes happen, and there can be many unknowns. In this post I’ll be discussing a recent over-the-air (OTA) software update to Rivian vehicles that went badly. It is speculative; I have no insider knowledge of Rivian’s software, systems or practices. […]
