Blog Writing for Developers (2023)
Writing is one of the most powerful forms of communication, and it’s useful in a multitude of roles and contexts. As a blog-writing , documentation-authoring , twitter-shitposting DevEx engineer I spend a lot of my time writing. Recently, someone paid me a very nice compliment about a blog I’d written and asked how…

From slow to SIMD: A Go optimization story
So, there's this function. It's called a lot. More importantly, all those calls are on the critical path of a key user interaction. Let's talk about making it fast.

Hash-based bisect debugging in compilers and runtimes
Does this sound familar? You make a change to a library to optimize its performance or clean up technical debt or fix a bug, only to get a bug report: some very large, incomprehensibly opaque test is now failing. Or you add a new compiler optimization with a similar result. Now you have a major debugging job in an…

Eplot: A new package for making charts in Emacs
One of the items on my todo list was: And that’s because I’ve been looking for an easy way to do simple plots for yonks. When I did a post about movie ratings, I tried chart.el: It̵…

Lossy CSS compression for fun and loss (or profit)
Late last year, I had an idea that’s been steadily brewing in my head. I’ve found myself with some free time recently (it coincided with vacation, go figure), and I’ve hacked together some proof-of-concept code. Whether or not it is actually proving the concept I’m not sure, but the results are somewhat interesting…

A practical introduction to constraint programming using CP-SAT and Python
We discuss constraint programming, an approach to solve discrete optimization problems, and illustrate how it works with a scheduling code example implemented in Python with the CP-SAT solver.

Building a single-page app with Htmx
People talk about htmx as though it's saving the web from single-page apps. Well, I guess I missed the memo, because I used htmx to build a single-page app.

A deep dive into Linux's new mseal syscall
If you love exploit mitigations, you may have heard of a new system call named mseal landing into the Linux kernel’s 6.10 release, providing a protection called “memory sealing.” Beyond notes from the authors, very little information about this mitigation exists. In this blog post, we’ll explain what this syscall is…

Monorepo – Our Experience
Nine months ago, we switched to a monorepo. Here's a detailed look at what led to the change, how we approached it, and what the experience has been like.

Gleam Is Pragmatic
I’ve spent the past several years working with functional programming languages in my free time – primarily Haskell and OCaml. I love both languages but also find aspects of each frustrating. Haskell is terse and elegant with type classes providing a powerful mechanism for ad-hoc polymorphism. However, it can also be…

Why bother with argv[0]?
The first argument of a program’s command line, typically reflecting the program’s name/path and often referred to as argv[0], can in most cases be set to an arbitrary value without affecting the process’ flow. Making the case against argv[0], this post demonstrates how it can be used to deceive security analysts…

Making Rust binaries smaller by default
Have you ever tried to compile a helloworld Rust program in --release mode? If yes, have you seen its binary size? Suffice to say, it’s not exactly small. Or at least it wasn’t small until recently. This post details how I found about the issue and my attempt to fix it in Cargo.

Coroutines and effects
For the past few months I’ve been mulling over some things that Russell Johnston made me realize about the relationship between effect systems and coroutines. You can read more of his thoughts on this subject here , but he made me realize that effect systems (like that found in Koka) and coroutines (like Rust’s async…

A Lisp compiler to RISC-V written in Lisp
This is a simple experimental Lisp compiler, written in uLisp, that will compile a Lisp function into RISC-V machine code. You can run the compiler on the RISC-V core of a Raspberry Pi Pico 2 (or another RP2350-based board):

The Performance Impact of C++'s `final` Keyword
If you're writing C++, there's a good reason (maybe...) as to why you are. And probably, that reason is performance. So often when reading about the language you'll find all sorts of " performance tips and tricks " or " do this instead because it's more efficient ". Sometimes you get a good explanation as to why you…
