Introducing facet: Reflection for Rust
I have long been at war against Rust compile times. Part of the solution for me was to buy my way into Apple Silicon dreamland, where builds are, like… faster. I remember every time I SSH into an x...
The virtue of unsynn
Addressing the rumors There have been rumors going around, in the Reddit thread for facet, my take on reflection in Rust, which happened a bit too early, but here we are, cat’s out of the bag, let’...
Open sourcing the home CMS
I’ve been bragging about my website software for years! For… whew, it’s been 5 years! I’ve been teasing folks about the cool things I did from the beginning — here are all the articles and series I...
The promise of Rust
The part that makes Rust scary is the part that makes it unique. And it’s also what I miss in other programming languages — let me explain! Rust syntax starts simple. This function prints a number:...

Highlighted code in slides
I have obsessed about this long enough, I think it’s only fair I (and you!) get some content out of it. When I started writing this article, I was working on my P99 CONF slides. Those slides happen...

Face cams: the missing guide
I try to avoid doing “meta” / “behind the scenes” stuff, because I usually feel like it has to be “earned”. How many YouTube channels are channels about making YouTube videos? Too many. Regardless,...
Just paying Figma $15/month because nothing else fucking works
My family wasn’t poor by any stretch of the imagination, but I was raised to avoid spending money whenever possible. I was also taught “it’s a poor craftsman that blames their tools”, which apparen...
Cracking Electron apps open
I use the draw.io desktop app to make diagrams for my website. I run it on an actual desktop, like Windows or macOS, but the asset pipeline that converts .drawio files, to .pdf, to .svg, and then t...
