So, I've always been somewhat annoyed at SSL/TLS. It requires everyone to go through a complex "ACME" dance just to put up a public website. Worse, certificates expire every few months, so it's not a one and done thing: even with automation, maintaining a certificate requires care to ensure the ACME client always has…
LLMs can make complete multi-level games that are fun.
Why a Rust developer might feel at home in Gleam, and where the BEAM is a different world.
malloc has a very nice and simple interface: you ask for a certain amount of memory, and you’re given a void pointer to your block of contiguous bytes that’s been magicked into existence. Once you’re done with it, you call free with the same pointer and the memory disappears into the ether.
Personal Notes
It's not about technology for its own sake. It's about being able to implement your ideas.
Why half a million people learned to program in Pascal, when you’d think they had no earthly reason to.
libghostty-vt 1.0 is here. libghostty is a portable, high-performance C library for terminal emulation, extracted directly from the core of Ghostty. The 1.0 release means both the library itself and the C ABI are now stable.
A series of articles about bare-metal programming for x86 PC-type computers, using Linux for development.
Extracting my gym’s QR check-in from its Flutter app, with a rooted phone and a lot of ripgrep.
Orchestrator-worker, blackboard, and pipeline patterns for coordinating multiple AI agents — with the failure modes that only show up once you go past a single-agent demo.
Buffered output typically comes in two flavors: fully buffered and line buffered. If output goes to a terminal then the implementation automatically selects line buffering, flushing its buffer when a line is completed so that it reaches the user immediately. Otherwise it fully buffers, holding output until the buffer…
Prompted by another project idea that popped into my mind, I did some Unix archaeology and looked at the original sources . This is the most fun I've ever had reading someone else's code - probably due to the historical significance. But also because of how delightfully approachable it was, compared to modern…
On October 23, 2026, the unthinkable happened. It was supposed to be a mere formality: C++26 was up for a vote by the ISO National Bodi...
macOS ships a VulgarWordUsage.db and a dictionary that rates every word as vulgar, offensive or sensitive. Dumped for 199,000 English words and a dozen other languages.
The LISP curse is often quoted as the reason why so few libraries and reusable components exist for LISP dialects. According to the concept, LISP is so power...
A recent paper argues that frontier LLMs can work with neural network weights directly. This seems superhuman, but it isn’t. The paper shows that GPT-6 Astra…
We find that frontier LLMs are surprisingly good at natively reading and writing neural network weights, using a variety of recent tools and algorithms or even via direct weight editing.
That morning I woke up at 6:58, two minutes before the alarm. I lay there and waited for it to ring. And it rang. We both did our jobs. I still don’t know why I remember it in such detail. I used to forget what I’d had for dinner the night before. And now I remember the whole morning minute by minute, as if someone…
From Pascal and ex tapes to a VAX system: Bill Joy handles BSD distribution and debugging, then joins Ozalp Babaoglu to bring virtual memory to Unix.
On efficient algorithms, the exponential time hypothesis, and losing the plot.
I’ve been fascinated with local LLMs for a couple of years now. The better open weight models, including some that inference on regular, higher-end consumer hardware at tolerable speeds, are now reliable enough to handle simpler programming tasks. This requires a coding harness, but so far this year I’ve been…
We have seen in a previous post that switch statements are more complex than they seem. The compiler is able to implement them as a decision tree (even though maybe it shouldn't). Is that everything it can do?
Over the past decade, the timing of PostgreSQL major releases has become very predictable: no earlier than the middle of September, and no l...
Yesterday, Anthropic were compromised and used to stage a global supply chain attack.

Good developers’ caution about agentic development comes from knowing that built isn’t the same as working in production.
This is what I built for Pwn2Own Berlin 2026 — a completely handmade, logic-only Microsoft Edge Full Chain, with no memory corruption, and no AI at all! 🔥
Several PDF implementations advertise AES-256, but generate the 256-bit key from either a very small state space, or from insecure random sources.
