Heads-up: An update to this article has been posted. There have been a lot of complaints about both the competency and the logic behind the latest Epstein archive release by the DoJ: from censoring…
Running six Claude Code agents in parallel from an iPhone. A cloud VM, Tailscale, mosh, and push notifications enable async development from anywhere.
Patterns for getting the best results out of coding agents like Claude Code and OpenAI Codex. See my introduction for more on this project.
Instant Linux microVMs with defense-in-depth security for running untrusted code.
For the past year and a half, the team building Roc 's compiler has been rewriting our 300,000 lines of Rust code into Zig , for reasons I'll recap below. We recently passed an exciting milestone: feature parity with the original compiler!
Radio buttons are built into web browsers. Why are we using a UI library that wraps another UI library that rebuilds radio buttons from scratch? Why does rendering a radio button require multiple dependencies and several kilobytes of JavaScript? How did we make a built-in browser control so complicated?
I’ve decided to archive the source code of my Ruby gems to make it clear that I’m no longer working on them; I’ve written this post to link from them in order to explain why.
98% sounds like a lot. If someone wins the lottery 98% of the times they play, they are clearly blessed. Getting a top mark (e.g.: 10/10) on exams 98% of the time will likely lead to an honour diploma.
A compressed 8KB docs index in AGENTS.md achieved 100% on Next.js 16 API evals. Skills maxed at 79%. Here's what we learned and how to set it up.
Bun is excellent software. Anthropic owns it now, Bun sits under Claude Code, and Claude Code getting worse makes me worried Bun could follow the same enshittification path.
A Look at Recurrent Depth, Hidden Chains of Thought, and Recent Research on Looping Transformer Blocks
Since launching Skip in 2023, we’ve pursued one mission: enable developers to create premium mobile apps for iOS and Android from a single Swift and SwiftUI codebase — without any of the compromises that have encumbered cross-platform development tools since, well, forever.
Pi Durable is a new experimental package for long-running, durable, and malleable agents that can run anywhere. A tour of what we built and why.
In order to avoid accuastions of this "just being Claude defending Claude," "AI slop," "probably all hallucinations," etc., I've decided it's probably worth explaining a few key points about how this report was created:
Today Reuters and the Wall Street Journal both reported about rogue AI agents at OpenAI attacking RubyGems.org. https://www.rubyhack.ai/ has an amazing writeup, and you should read it. I just wanted to make a quick post about it because it’s wild. TL;DR: It seems like OpenAI Bots knew about the RubyGems caching…
It's not about technology for its own sake. It's about being able to implement your ideas.
Brave has overhauled its Rust-based adblock engine to reduce memory consumption by 75%, bringing better battery life and smoother multitasking to all users.
A systems analysis of how AI-assisted development creates a gap between output speed and understanding, and why organizations cannot see it happening.
Short architecture note on Kimi K3, including LatentMoE, Kimi Delta Attention, Attention Residuals, NoPE, multimodality, and inference-efficiency choices.
If he had been a programmer, Cardinal Richelieu would have said “Give me six lines written by the hand of the most expert C programmer in the world, and I wi...
We've all worked with a rockstar developer. They joined the team years ago, full of energy. They had great ideas about new tech, new paradigms, new architectures. Their cutting-edge ideas left everyone else feeling a bit behind and outdated.
I think it’s important to be very Canny when someone makes a claim that supports a company’s large valuation.
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 …
Two years ago, I was Porting my JavaScript Game Engine to C for No Reason . I have since found a reason: making a new N64 game!
I never thought it could happen to me. I mean, parentheses? In this day and age? But for the past couple years, my go-to programming language for fun side projects has been a little Lisp dialect called Janet. (print "hey janet") I like Janet so much that I wrote an entire book about it, and put it on The Internet for…
A brief look at the three main causes of bloat in our JavaScript dependency trees, and how we can start to address them.
A blog by James Adam, of lazyatom.com fame.
How do you review code at the volume agents produce it? On the Claude Code team, once we had high coverage and deep reviews, we started optimizing for the minimum amount of human review time that doesn't raise reverts or incidents.
Cloudflare's global network is immense but not limitless. As we look for small ways to trim our resource usage, we sometimes get lucky and we can cut significantly more. Here’s how we reduced one of our Pingora-based service's RAM usage with statistics.
