Stop crawling my HTML – use the API
One of the (many) depressing things about the "AI" future in which we're living, is that it exposes just how many people are willing to outsource their critical thinking. Brute force is preferred to thinking about how to efficiently tackle a problem. For some reason, my websites are regularly targetted by "scrapers"…

A guide to Gen AI / LLM vibecoding for expert programmers
I get it, you’re too good to vibe code. You’re a senior developer who has been doing this for 20 years and knows the system like the back of your hand. Or maybe you’re the star individual contributor who is the only person who can ever figure out how to solve the hard problems. Or maybe you’re the professor who…

The Evolution of Caching Libraries in Go
For the last few years, I've been developing caching library, and today I'd like to talk about the evolution of caches in Go and where we stand today. Especially since Go 1.24 was officially supposed to focus on caching improvements, but I haven't heard much news about them - time to fix that .

Rootless Pings in Rust
Sending a ping by creating an ICMP socket normally requires root: you can’t create a raw socket to send ICMP packets without it. The ping command line tool works without root however, how is that possible? It turns out you can create a UDP socket with a protocol flag, which allows you to send the ping rootless. I…

The inconceivable types of Rust: How to make self-borrows safe (2024)
One of the first things any Rust programmer learns is that you can’t pass an object and a reference to that object around at the same time. It’s impossible to do, even indirectly. This limitation has been the subject of countless questions on Stack Overflow and posts on Reddit and the Rust forums and anywhere else…

Data evolution with set-theoretic types
We explore how set-theoretic types could address how many statically typed languages do not allow libraries to evolve their public data definitions in a backwards compatible manner. The proposed solution aims to be automatically verified by the compiler and type safe.

Beyond OpenMP in C++ and Rust: Taskflow, Rayon, Fork Union
Most C++ and Rust thread pools run 10x slower than OpenMP on fork-join workloads. Fork Union closes the gap to 20% with 300 lines, dodging mutexes and CAS.
