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…
There are a lot of places you’ll see * and ** used in Python. These two operators can be a bit mysterious at times, both for brand new programmers...
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
If you’ve read anything about compilers in the last two decades or so, you have almost certainly heard of SSA compilers , a popular architecture featured in many optimizing compilers, including ahead-of-time compilers such as LLVM, GCC, Go, CUDA (and various shader compilers), Swift 1 , and MSVC 2 , and just-in-time…

In my last blog entry LLand LR Parsing Demystified, we explored LL and LR parsers from ablack-box perspective. We arrived at a model for these parsers whereb...
Introduction Two months ago, I bought a new battery for my Lenovo laptop (a ThinkPad X230T). I was about to go away on holidays and wanted a battery that could last me through a plane flight; the original battery was by then barely lasting ten minutes. Little did I know that I was about to be i

How I went about creating a concealed modification for a fan so I could control it over WiFi with ESPHome and Home Assistant.

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.
I wanted to know what third-party code I was using in my GitHub Actions. I was able to use standard text processing tools and shell pipelines to get a quick tally.

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…
Once upon a time we were creatures in the wilderness and we evolved the ability to hear sounds. Now here's an interesting thing, if you hear a sound of frequency f and others of frequency 2f, 3f, etc then there's a good chance these sounds come from the same object, due to the physical principle of resonance . And so…
tl;dr: I successfully got the Intel I340-T4 4x Gigabit NIC working on the Raspberry Pi Compute Module 4, and combining all the interfaces (including the internal Pi interface), I could get up to 3.06 Gbps maximum sustained throughput. Update: I was able to boost things a bit to get 4.15 Gbps! Check out my video here…
Rust's error handling is a pleasure to use thanks to the Result type . It ensures Rust's error handling is always correct , visible , and performant . And with the addition of the ? operator in Rust 1.13 , and the addition of return types from main in Rust 1.26 Rust's error handling has only kept improving.

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…
Couple months ago, a friend sent me this article about "Speed learner Max Deutsch challenging chess grandmaster Magnus Carlsen". My friend ...
GPT4-V is the new mode of GPT-4 that allows you to upload images as part of your conversations. It’s absolutely brilliant. It also provides a whole new set of vectors …
On Saturday 11th March I wrote about how Large language models are having their Stable Diffusion moment. Today is Monday. Let’s look at what’s happened in the past three days. …
As you may, or may not know, I wrote paraLLEl-RDP back in 2020. It aimed at implementing the N64 RDP in Vulkan compute. Lightning fast, and extremely accurate, plus the added support of up-scaling on top. I’m quite happy how it turned out. Of course, the extreme accuracy was due to Angrylion being used as reference…
