Things you can do with a debugger but not with print debugging
People do or do not use debuggers for a variety of reasons. For one thing, they are hard to setup in many codebases. Second, you can’t use them when your application is running on remote environments (such as kuberenetes). So, anecdotally, I have seen way more people using Print/ log.Debug compared to a debugger.

Things Unix can do atomically (2010)
This is a catalog of things UNIX-like/POSIX-compliant operating systems can do atomically, making them useful as building blocks for thread-safe and multi-process-safe programs without mutexes or read/write locks. The list is by no means exhaustive and I expect it to be updated frequently for the foreseeable future.

HTML over WebSockets: real-time SPAs with barely any JavaScript

My PhD advisor rewrote himself in bash (2010)
The point of these scripts is not to ban all use of constructs like the passive voice. (When it comes to writing, there are exceptions to every "rule.")

Htmx and Web Components: A Perfect Match
Web Components are a set of browser APIs that allow us to create custom HTML elements. They are one of the major things that SPA (Single Page Application) frameworks have been giving us for a long time ... HTMX is highly interesting, useful and a promising technology. It simplifies many things and allows us to build…

A fork() in the road
The received wisdom suggests that Unix’s unusual combination of fork() and exec() for process creation was an inspired design. In this paper, we argue that fork was a clever hack for machines and programs of the 1970s that has long outlived its usefulness and is now a liability. We catalog the ways in which fork […]

How we built the Waifu Vending Machine
On the weekend of Anime Expo, an artist promised the humanly impossible -- custom art commissions with a five-minute turnaround time. The not-so-hidden catch? The artist wasn't a human at all, but an AI exposed to millions of anime images.

REST Servers in Go: Part 1 – standard library
This is the first post in a series about writing REST servers in Go. My plan with this series is to implement a simple REST server using several different approaches, which should make it easy to compare and contrast these approaches and their relative merits.

Fable 5 vs. GPT-5.6 Sol on an NP-Hard Problem: Does /goal help?
I gave Claude Fable 5 and GPT-5.6 Sol the same unpublished NP-hard optimization problem, with and without their native /goal mode. Fable 5 is a beast; /goal is not a game changer.
