Skip is now free and open source
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.

Nested code fences in Markdown
Today, we will meet a spiky-haired nerd named Corey Dumm, who normally lives within Markdown code fences. We will get to know him a bit, smile with him when his fences hold and weep quietly when misfortune strikes.

Vibecoding #2
I feel like I got substantial value out of Claude today, and want to document it. I am at the tail end of AI adoption, so I don't expect to say anything particularly useful or novel. However, I am constantly complaining about the lack of boring AI posts, so it's only proper if I write one.

I built a 2x faster lexer, then discovered I/O was the real bottleneck
Archiving 104K files into tar.gz reduced I/O time by 43x and total processing time by 2.3x. The bottleneck was not disk speed, it was syscall overhead.

The Overcomplexity of the Shadcn Radio Button
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?

Floating-Point Printing and Parsing Can Be Simple and Fast
A floating point number f has the form f = m · 2 e where m is called the mantissa and e is a signed integer exponent . We like to read numbers scaled by powers of ten, not two, so computers need algorithms to convert binary floating-point to and from decimal text. My 2011 post “ Floating Point to Decimal Conversion is…

SIMD programming in pure Rust
I've recently tasted AMD Zen 5 CPUs (AWS' m8a instances) and... Whooaaa. Even before talking about GPUs and NPUs, the next 5 years of CPUs will be very exciting! For

Some C habits I employ for the modern day
Despite it being the first “proper” programming language I learned—by reading K&R front-to-back no less—I don’t write C too terribly often nowadays. Playing resonite has gotten me into writing a load of C# for modding the game, and most of what I do day-to-day is automating the tedium on my computer, which gets…

Provide agents with automated feedback
Back pressure for agents You might notice a pattern in the most successful applications of agents over the last year. Projects that are able to setup structure around the agent itself, to provide it with automated feedback on quality and correctness, have been able to push them to work on longer horizon tasks. This…
