6 weeks of Claude Code
It is wild to think that it has been only a handful of weeks. Claude Code has considerably changed my relationship to writing and maintaining code at scale. I still write code at the same level of quality, but I feel like I have a new freedom of expression which is hard to fully articulate. Claude Code has decoupled…

I know when you're vibe coding
I shouldn't have to care about this. I don't want to care about how someone's code gets into the IDE. Whether you wrote it by hand, copied it from a forum, prom

Microsoft became incompetent in IT
You know what: Microsoft became miserably incompetent in IT. I develop open-source code. But that never made me one of the “I hate proprietary software or IT giant corporations” types. …

Emacs: The macOS Bug
The Context I have been recently roaming. Doing some Zig, doing some Go, some Janet. Some C integration. Should have focused on my project but life threw more at me than I could handle, so I sought… happy distractions. My experience with those technologies taught me new tricks and one day, when I needed some more…

Writing memory efficient C structs
A struct in C is the best way to organize your data so that you can easily use the data later in your program. However, there are a few caveats to C structures, mainly how their memory works. Note that I’m making a lot of assumptions about type sizes and standards. These can differ between systems and ABI’s, so for…

My 2.5 year old laptop can write Space Invaders in JavaScript now (GLM-4.5 Air)
I wrote about the new GLM-4.5 model family yesterday—new open weight (MIT licensed) models from Z.ai in China which their benchmarks claim score highly in coding even against models such …

Zig Profiling on Apple Silicon
If you’re a developer rocking an Apple Silicon Mac and writing in Zig, congratulations - you’ve chosen the scenic route through the desert of profiling tools. It’s just you, your code, and a tumbleweed named Apple Instruments. But don’t worry - we’ll try to find some oases. Okay, it’s not that bad, but we’re far away…

SIMD within a register: How I doubled hash table lookup performance
It started with a simple thought: four bytes in a hash table bucket look just like an integer. Luckily, this one idea led to a deep dive into bit-twiddling and a 2x performance boost.

Resizable structs in Zig
In this post I will make the case for the concept of a “runtime resizable struct” in Zig. I will then design an API by exploiting Zig’s powerful comptime functionality.

It's time for modern CSS to kill the SPA
Native CSS transitions have quietly killed the strongest argument for client-side routing. Yet people keep building terrible apps instead of performant websites.
