The transition to the Rust version of the React Compiler for the 1,036-file React Router codebase resulted in a significant speed increase, improving build times from 14.3 seconds to 0.81 seconds. The new compiler addresses previous limitations and ensures consistency across the toolchain, making it easier to manage…
Or: Why do I always do things the hard way?
small programs hide coupling
A lot of the educators I admire in the frontend web space seem to be either bowing out or dialing back their efforts: Axel Rauschmayer, Salma Alam-Naylor, Josh…
A guide to bringing up the Linux Kernel and a userspace application on a new hardware (or in this case, a self-made emulator)
Babylonian Twins is an Amiga platformer I built in Baghdad in 1993, in 68000 assembly. This summer an LLM ported it to Godot, and this is what I found when I read back through what it did. The original disks are now free on itch.io.
Go 1.24 replaced the built-in map’s bucket-based runtime with Swiss Tables. This article explains groups, control bytes, H1 and H2, probing, table growth, directories, deletion, load factor, and the experimental split-group layout.
Preview of Python Polars 2.0, bringing the streaming engine to all lazy queries
I can't play an instrument, so I worked out music theory in JavaScript instead. Twelve notes, scales and chords, derived from scratch with code you can hear.
It's time for another technical blog post about async Rust on embedded. This time we're going to pitch Embassy/Rust against FreeRTOS/C on an STM32F446 microcontroller.

Stripe Across is a grog. We hope you enjoy it.
When talking about TLA+, I keep referring to "abstraction" as the most important thing to learn . And it is about the hardest to learn as w...
I was poking around in my ~/.cache/ folder using OmniDiskSweeper when I spotted something interesting. The OpenAI Codex desktop app (since rebranded to just ChatGPT) has 1.7GB of stuff in …
From the Zed Blog: Ted Nelson specified the docuverse sixty years ago. The technology finally arrived, and so did its native users.
After 15 years at Google, the creator of JJ joins ERSC as Chief Technology Officer.
The one where I build my own text editor (until I get bored).
Someone opened a PR to implement readahead in Turso. It was a throwaway implementation, but a good excuse to measure io_uring and understand more about it.
The optimizations behind Wasmi 2.0, and how they compare to Wasm3 and Stitch.
Read this Tcl/Tk hands-up/primer to find out how the open-source Command Tool Language toolkit can help you develop cross-plaform tools for Windows, Linux, macOS and even Android.
We are rebuilding Monica from scratch, and this new series will document how.
An Introduction to File Formats and ImHex by Reverse Engineering FEZ's Save File Format
Memoryfields - a vastly simpler way to do agent memory
In 2019 I bet on the no-code revolution. That bet aged so-so. Here is the new one.
Julia, the programming language that originated as a research project at MIT, has gained a loyal following among scientists, engineers, mathematicians, and others. The free and open-source language counts more than 1 million users, including people at thousands of companies and universities around the world.
An introduction to diffusion language models and the research advances that underlie today's diffusion LLMs. We describe the building blocks of recent open-source models, starting from simple masking diffusion, and including techniques for iterative refinement, post-training, and variable-length generation. Material…
I used to wonder why I see so many more bugs than most people. I easily observe hundreds to thousands of bugs per week and nothing seems to work , but most people I talk to don't see anything like this . For a long time, I thought this had something to do with how I use computers but, over time, I've realized that…
I never questioned why code should be highlighted until I tried to make my own theme.
I've spent most of my career working inside the JVM, with a sidebar of Python. So the first time I hit incompatible libc with containerized Bifrost, and GPT suggested musl as the solution, not only did I jump on it, I moved my other Rust projects to musl as
