Erlang's not about lightweight processes and message passing (2023)
I used to think that the big idea of Erlang is its lightweight processes and message passing. Over the last couple of years I’ve realised that there’s a bigger insight to be had, and in this post I’d like to share it with you.

Playing in the Creek
When I was a really small kid, one of my favorite activities was to try and dam up the creek in my backyard. I would carefully move rocks into high walls, pile up leaves, or try patching the holes with sand. The goal was just to see how high I could get the lake, knowing that if I plugged every hole, eventually the…

My Own Private Binary: An Idiosyncratic Introduction to Linux Kernel Modules
Several years ago, I spent a serious chunk of time figuring out how to make really teensy ELF executable files. I started down this path because I was annoyed that all of my programs, no matter how short they were, never got smaller than 4k or so. I felt that was excessive, for C, and so I started looking at what ELF…

Parser Combinators Beat Regexes
Someone online was solving Advent of Code problems, and had a question about last years’ day 3 . They had a working solution using regular expressions (regexes) on String values, but they wanted to use ByteString values instead for performance reasons. They were surprised, however, that there seems to be a lack of…
