Java 17 introduced sealed classes, which allow you to explicitly list the allowed sub-types of an interface or base class. For example, here’s a toy example using a sealed interface and records (in…
Have you ever had a weird idea, and then it worked, but you can't really believe it?
Better than regex!
I built KillSwitch, an esoteric language designed to confound LLMs and coding agents, and benchmarked the major models against it.
This release will be the Reference Implementation of version 28 of the Java SE Platform, as specified by JSR 403 in the Java Community Process.
Programming is fun!
Making an 88x31 book-button using ImageMagick
How do you review code at the volume agents produce it? On the Claude Code team, once we had high coverage and deep reviews, we started optimizing for the minimum amount of human review time that doesn't raise reverts or incidents.
If you’ve ever needed to hit a breakpoint programmatically in C++, you’ve probably written something like this: 1 2 3 4 5 6 7 8 9 #if defined(_MSC_VER) __debugbreak(); #elif defined(__clang__) __builtin_debugtrap(); #elif defined(__GNUC__) && (defined(__i386__) || defined(__x86_64__)) __asm__ volatile("int3"); #else…
Sharp pixels, gritty colour banding, and DOS games running at resolutions their own era couldn’t manage. Why I still prefer the software renderer, and why it needs a fast PC.

Monte Carlo simulations (or methods ) is the technique of applying randomness and the Law of large numbers to the solution of various scientific and engineering problems. One of its first documented uses was by Stanislaw Ulam and John von Neumann for nuclear weapon simulations after WWII [1] .
As our merges per day grew more than tenfold, source control became our biggest development bottleneck. Here, we share how we migrated to an in-house version control system in five months.
An aggregation is some kind of summary of a set of data. This can be the sum, length, minimum, etc. It is quite common to want to calculate such a summary repeatedly, e.g. “the maximum noise level in dB for the past 30 seconds” for a nuisance detector. In such a case we say there is a sliding window over our data, and…
this is an incomplete list of some incompatibilities between c as it's written in the standard and c as it exists in the real world for people who use gcc/clang + glibc/musl.
LittleJS just got the biggest update since it launched! It is still the small, fast, dependency-free HTML5 game engine it always was. Now it also has a full 3D renderer sharing the canvas with your…
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…
In the late 80s, I spent an embarrassing number of hours hunched over my ZX Spectrum, typing in Sinclair BASIC programs and rudimentary assembler routines copied from magazines, trying to re-create the Amiga crack intros I’d seen round at a friend’s house. Obviously, they never came even slightly close - but now, many…

Measuring a commercial spatial audio processor, extracting its stereo impulse responses, and rebuilding the effect as a convolution filter on Linux.
DHH, the creator of the Ruby on Rails framework, decided to rewrite Campfire Once from Ruby on Rails to Rust. Or rather ask a clanker to do it for him, as he can't stand reading or writing the Rust code himself. After that he added rewrites in other languages , like Elixir and Go.
I was playing with the nono agent sandboxing tool and it greeted me with a warning: PATH entries the sandbox can write to: ~/.local/bin/ which looked suspicious.
You all know me, I love exploring new memory safety approaches and blending them together in weird ways.
