Hide macOS Tahoe's Menu Icons
I really dislike Apple’s choice to clutter macOS Tahoe’s menus with icons. It makes menus hard to scan, and a bunch of the icons Apple has chosen make no sense and are inconsistent between system applications. Steve Troughton-Smith is my hero for finding a Terminal command to disable them: Here’s one for the…

The bespoke software revolution? I'm not buying it
A bespoke software revolution? I don't buy it. It'll exist. It already exists. Small consultants and big consulting firms have made custom software for years. It almost always sucks. It’s bloated, confusing, and because the client pays, it’s built in all the wrong ways. Who’s excited about bespoke software? Software…

Java is fast, code might not be
Fixing common Java anti-patterns took an app from 1,198ms to 239ms. Eight patterns that compile fine and pass code review but silently drain CPU and balloon heap, with benchmarks and code fixes for each

Finding all regex matches has always been O(n²)
every regex engine that promises linear time breaks that promise the moment you ask for all matches. the problem has been there since the 70s, hiding in the iteration loop.

The Shape of Inequalities
…symmetry isn’t just a preference for “pretty” shapes. Contents Introduction The HM-GM-AM-QM Inequality The two circles The Semicircle The Container The 3D container The Sum of Squares Inequality Nesbitt’s Inequality Conclusion Introduction While I was randomly browsing the web, I came across this nice picture: Roland…

Celebrating Tony Hoare's mark on computer science
Tony Hoare at the LASER summer school, September 2007 (All photographs in this article are by the author) Had they included just one of Tony Hoare’s major achievements, many scientific careers would be considered prestigious enough. His had a long list, which I am going to try to summarize, not pretending to get…

A tale about fixing eBPF spinlock issues in the Linux kernel
A system freeze led us deep into Linux spinlock internals, where we helped find not one but three bugs in the kernel's resilient locking code used by eBPF.

A Decade of Slug
What is now known as the Slug Algorithm for rendering fonts directly from Bézier curves on the GPU was developed in the Fall of 2016, so this year marks a full decade since its inception. I published a paper in JCGT about the technique in the middle of 2017, and my company sold the first license for version 1.0 of the…

If you thought code writing speed was your problem you have bigger problems
AI coding tools are optimising the wrong thing and nobody wants to hear it. Writing code was already fast. The bottleneck is everything else: unclear requirements, review queues, terrified deploy…

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.

An ode to bzip
The story goes like this. ComputerCraft is a mod that adds programming to Minecraft. You write Lua code that gets executed by a bespoke interpreter with access to world APIs, and now you’re writing code instead of having fun. Computers have limited disk space, and my /nix folder is growing out of control, so I need to…

AI didn't simplify software engineering: It just made bad engineering easier
AI tools lower the barrier to producing code, not to building reliable systems. The hard part — maintaining alignment between specifications, tests, and implementation — has not gone away. Expertise still matters.

Are LLM merge rates not getting better?
I was reading the metr article on how llm code passes test much more often than it is of mergeable quality . They look at the performance of llm s doing programming when the success criterion is “passes all tests” and compare it to when the success criterion is “would get approved by the maintainer”. Unsurprisingly…
