I tested 10 model/harness combinations on the same Three.js task
I've been testing a simple prompt with different model and harness combinations to work out which one produces best results. I do this in /goal mode.

Clamiga: Common Lisp for the Amiga
After the ACE BASIC posts of the last months, this one is about a different project I have been working on for the last half year: CL-Amiga , or Clamiga for short. It is a Common Lisp implementation built for the Amiga family -- classic AmigaOS 3 on 68k and MorphOS as a fully native PPC build, AROS and AmigaOS 4 maybe…

Excessive nil pointer checks in Go
Let’s talk about nil pointer checks in Go. You want to prevent panics in production, but that doesn’t start with a deferred recover. It starts with defensive programming. Check your inputs, check your bounds, and check pointers for nil before dereferencing them. I’ve started to see more nil checks in Go code. In the…

Lisp moving Forth moving Lisp
This chapter is a culmination of many macro techniques we have looked at so far in this book. Using macro abstractions we have developed, we create an implementation of one of my favourite programming languages: forth . Although this implementation embodies most of the important ideas of forth, it is very different…

Even faster asin() was staring right at me
I don't normally do follow-ups and never this quick. After posting that last article, it was fun to read the comments on Reddit and Hacker News as they rolled in. I even found other discussions . I couldn't help wonder, "Could I have made it even more performant?" . After heading home I decided to take another look.

Gpiozero Flow
Back in 2015, I had the idea for gpiozero — a Python library for Raspberry Pi, making programming GPIO devices simpler by abstraction: instead of thinking about pin channels, voltages, pull-up resistors and rising or falling edges, we think about buttons being pressed and released, sensors...

80386 Protection
I'm building an 80386-compatible core in SystemVerilog and blogging the process. In the previous post , we looked at how the 386 reuses one barrel shifter for all shift and rotate instructions. This time we move from real mode to protected and talk about protection .

C++26: The Oxford Variadic Comma
C++26 brings us a small but meaningful cleanup to the language: deprecating ellipsis parameters without a preceding comma. This change, proposed in P3176R1, aims to improve C compatibility, reduce confusion, and pave the way for future language features. The proposal’s name is a playful reference to the Oxford comma …

Tracking down a Zsh history data loss bug
For many years, I sometimes discovered that commands I was sure I had run were no longer present in my Z shell history file (~/.zsh_history). In this article, I will show you how I tracked down the bug. Spoiler: ultimately, patching Zsh to make it crash loudly and analyzing the crash’s core dump was the winning…

How Do I Profile eBPF Code?
If we are running any eBPF workload or writing eBPF code, we want to measure its performance impact, and in this post we will demonstrate an example of how to do it. In this example, our goal is to measure the performance of file open operations, one of the most critical functions in the OS. Our code used file open…
