Cursed Linear Types in Rust
Inspired by Jack Wrenn’s post on Undroppable Types in Rust, I set out to see if it’s possible to create types that must be used exactly once. From my understanding, those things are called linear types, but don’t quote me on that1. Unless you are quoting the title of this article which explicitly says linear types… I…

On the Costs of Syscalls (2021)
It's well known that syscalls are expensive. And that software mitigations against CPU bugs (such as Meltdown) even have made them more expensive. But how expensive are they really? To begin to answer this question I wrote a small micro-benchmark in order to measure the minimal costs of a syscall …

Ditching PaaS: Why I Went Back to Self-Hosting
I had never been a fan of devops/server-admin work. The sheer number of headaches involved in setting up the services, configuring them, automating them, and ensuring their reliability were just annoying and time-consuming. PaaS offerings like Heroku, AWS—and later—Railway, and Render, were appealing options out of…

Ruby might be faster than you think
I saw a project a couple weeks back which allows writing and running Crystal methods inline inside a Ruby file. It’s a neat project, and I don’t want to take away from it but something in the README example looked off to me. require 'crystalruby' require 'benchmark' module Fibonnaci crystalize [n:
