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…

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…

Christmas is coming again, and generally that means christmas trees and everything in it: lights, streamers, and ofcourse baubles. The holiday is all very jolly and everything, so I decided it was lacking some doom... errm, I mean Doom. So I 3d-printed a small Christmas bauble modeled on an IBM PC, stuffed it with the…
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.

vfmaddrnd231pd is a unique instruction from the FMA instruction set. Most instructions in that set have mnemonics like vfmadd231pd, but here rnd means something very specific. The Intel Software Development Manual documents it as: VFMADDRND231PD – Fused Multiply-Add of Packed Double-Precision Floating-Point Values…
This article was originally written in 2014, but has had some minor improvements in December 2017 and January 2018 when I received some useful feedback after the article had unexpectedly been posted on Hacker News in December 2017.
Using ARIMA model, you can forecast a time series using the series past values. In this post, we build an optimal ARIMA model from scratch and extend it to Seasonal ARIMA (SARIMA) and SARIMAX models. You will also see how to build autoarima models in python
The artist M.C. Escher drew many lovely tilings, which he called “regular divisions of the plane”. He worked hard to ensure that his tilings were of lifelike animal forms such as birds and fish. He filled notebooks with hand-drawn sketches of tilings, many of which later found their way into his woodcuts. If you’d…
Finally, we train an LLM! The final part of Chapter 5 of Build an LLM (from Scratch) runs the model on real text, then loads OpenAI’s GPT-2 weights for comparison.
For almost two years now, the vast majority of our backend code was written in Rust (aside from a little bit of Python). I love Rust, it’s by far my favorite language. I find myself missing match in pretty much every other language I go to. However, if I was doing it over, I wouldn’t choose Rust. This advice is…
After 15 years on macOS, I made the leap to Arch Linux using Omarchy. Here's what I discovered about the trade-offs, workflow changes, and why shorter battery life and fan noise haven't sent me back to my MacBook.
It’s 11:43pm on a Monday night. My 6-week-old son is asleep in my office so my wife can get some uninterrupted rest for the first half of the night. He’s finally asleep now, and I probably should be also after a full day of work. But I’m not done for the day. Even though I’m a software engineer by trade, I’m also a…
