My First Impressions of Nix
Nix is a tool for configuring software environments according to source files. I’ve been hearing more and more about Nix on Hacker News and Twitter. The idea of it appeals to me, so I’ve been tinkering with it over the past few weeks. My history with infrastructure as code Ten years ago, I discovered Salt, a tool that…

Making C++ safe without borrow checking, reference counting, or tracing GC

Claude is not your architect. Stop letting it pretend
Somewhere between 'ask Claude for a quick opinion' and 'Claude is writing our Jira tickets,' we lost the plot. AI agents are brilliant implementers. They're also confidently wrong about every decision that matters. And when it all falls over, they won't be the ones carrying the bag.

In my previous post I said that the lang team would be making our final decision about the syntax of the await operator in the May 23 meeting. That was last Thursday, and we did reach a decision. In brief, we decided to go forward with the preliminary proposal I outlined earlier: a postfix dot syntax, future.await…

tolower() with AVX-512
A couple of years ago I wrote about tolower() in bulk at speed using SWAR tricks . A couple of days ago I was interested by Olivier Giniaux’s article about unsafe read beyond of death , an optimization for handling small strings with SIMD instructions, for a fast hash function written in Rust.

Reverse geocoding is hard
My wife and I run OpenBenches - a crowd-sourced database of nearly 40,000 memorial benches. Every bench is geo-tagged with a latitude and longitude. But how do you go from a string of digits to something human readable? How do I turn -33.755780,150.603769 into "42 Wallaby Way, Sydney, Australia"? Luckily, that's a…

JS things I didn’t know existed
I was reading through the MDN docs the other day and found these JS features and APIs I never knew existed. So here is a short list of those things, useful or not - learning JS seemingly never ends. Label Statements [https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/

Send text messages for free using Python
Using SMS and MMS gateways we can send text messages to phones from a computer via email. With this strategy we can use a combination of the Python SMTP and email library to send text messages programmatically for free! This not only includes short text messages, but also multimedia messages with pictures, videos, or…

My “grand vision” for Rust
I don’t think I’ve ever quite articulated my “grand vision” for Rust, despite having written a fair bit about the language and its features. There is a lot I could say here, but currently there are three directions of development which I find particularly interesting:

Zig's Incremental Compilation Internals
As a member of the Zig core team, one of the most impactful projects I’ve been involved with is the implementation of incremental compilation into the Zig compiler. This feature allows the compiler to detect which individual functions and declarations have changed since a project was last built, recompile only that…
