Joel Spolsky: Can your programming language do this?
One day, you’re browsing through your code, and you notice two big blocks that look almost exactly the same. In fact, they’re exactly the same, except that one block refers to “Sp…

A Formula for the Number of Days in Each Month
Recently, after being awake for longer than I should have, I started thinking about methods of remembering the number of days in each month of the year. There is a rhyme for it, and a way to count on your knuckles, but these didn’t satisfy me. I wondered if there was a mathematical formula for the problem, and upon…

Milwaukee M18 Battery Reverse Engineering
2023-01-01: This project has been ongoing for a while... now its time to post some of this info and see what comes of it. I have access to several junk Milwaukee M18 batteries. Age varies a little. I thought it would be 'fun' to reverse engineer a battery just to see how it functions... That is until I actually opened

Why is there a “V” in SIGSEGV Segmentation Fault?
My program received a SIGSEGV signal and crashed with "Segmentation Fault" message. Where does the "V" come from? Did I read it wrong? Was there a "Segmentation *V*ault?"? Or did Linux authors make a mistake? Shouldn't the signal be named SIGSEGF?

What you could steal from the Kakoune code editor, and get away with
Kakoune is a (fairly) young modal code editor that has matured for as long and as well as a good red wine. It places multiple-selections, operability and interactivity at the heart of its distinctive characteristics. It provides users with an efficient and comfortable text editing experience — but that’s not what this…

I failed to make LinkedIn fix their broken international domain URL parser
In Denmark it is possible to register domains with funny characters such as æ, ø and å. And we do. One prominent example is our national portal for booking Covid-19 tests at https://coronaprøver.dk . Wikipedia calls these beasts Internationalised domain names , so they must indeed exist.

Turning Claude Code into my best design partner
When I first started using Claude Code, I had a naive approach to working with it. I would describe the task directly in the prompt, press Enter, and cross my fingers. If the agent made mistakes, I would tell it how to fix them. For small tasks, this can be good enough, but as the task grows in complexity, this…

Rust 2020: GUI and Community
In response to the call for blogs about the vision for Rust for 2020, I’m going to write about GUI. I believe the time is right for a native GUI toolkit written in Rust, and that such a thing would fill a very important niche. There is a demand for performance (which, to me, includes startup time, RAM footprint, and…
