Somewhere between 'ask Claude for a quick opinion' and 'Claude is writing our Jira tickets,' we lost the plot. AI agents are brilliant implementers. They're also confidently wrong about every decision that matters. And when it all falls over, they won't be the ones carrying the bag.
Learnings from post-AI Open Source and how we’re approaching this so far.
Classical CPU architecture is a poor choice for performing matrix-oriented computations. Developers have to spend much effort to create efficient algorithms even for the problems appearing trivial on the surface. Matrix transpose is probably the most striking representative of such problems. It exposes numerous…
Released at the Outline Demoparty in May 2026, Ommen, NL An exploration of algorithmic density in 16 bytes of x86 assembly.
tiling window managers are wonderful. ultra-flexible text editors are also wonderful. for a spell, i thought i'd found the ideal solution in exwm … and i think it would have been, save for the fact that i use ordinary, graphical windows as much, if not more than, text buffers, and sometimes those windows are from…
This is going to be a rant about modern web design practices. But before I get to that, let me begin with a familiar principle from the world of cryptography. Among software developers, and especially among those who work on security-sensitive systems, there is a well-known maxim: Don't roll your own crypto. This does…
This is the fifth installment of the 80386 series . The FPGA CPU is now far enough along to run real software, and this post is about how it works. z386 is a 386-class CPU built around the original Intel microcode, in the same spirit as z8086 .
A proposed technique for exposing an opaque data structure with idiomatic modern Python.
So, you want to improve the performance of your deep learning model. How might you approach such a task? Often, folk fall back to a grab-bag of tricks that might've worked before or saw on a tweet. "Use in-place operations! Set gradients to None! Install PyTorch 1.10.0 but not 1.10.1!"
What if we dutifully communicate the risks and trade-offs to our organizational leadership and they still want to take those risks
With the latest release of corecrypto, we’re publishing our implementations of quantum-secure ML-KEM and ML-DSA algorithms, along with the mathematical proofs we built to assure they are faithful to the FIPS 203 and FIPS 204 specifications. To advance the state of the art for assuring critical software, we're also…
How a software developer bypassed proprietary publishing silos using LibreOffice, Standard Ebooks, and LaTeX to build a sustainable, Git-tracked book production pipeline.
Why coding agents perform better in cohesive ecosystems like Go than fragmented ones like JavaScript or Python
errno(2) values for the AI age
In response to a question on Twitter 1 , Richard Hipp wrote about why SQLite uses a bytecode VM for executing SQL statements.
In this post I discuss the support for union types released in .NET 11, how they're implemented, the choices made, and how to create your own
`import defer`, six new subcommands (`deno transpile`, `deno pack`, `deno bump-version`, `deno ci`, `deno why`, `deno audit fix`), network debugging in Chrome DevTools, framework-aware `deno compile`, and 3.66x faster cold npm installs.
A practical OpenSCAD LLM benchmark comparing Codex 5.5 High, Claude Sonnet, Claude Opus, Cursor Composer, Google Antigravity, and ModelRift on a detailed Pantheon model.
uv's CLI feels surprisingly clunky compared to its peers like pnpm or Poetry.
A 2026 sequel to C Constructs That Don't Work in C++: what still breaks, what C++20 changed, and what C23 changed.
The `unsafe` keyword is being redesigned to mark caller-facing contracts rather than just syntax. Safety obligations between callers and callees become visible and reviewable. The model is motivated by the rise of AI-assisted code generation and arrives as a preview in .NET 11.
It's that time of the year again, a new version of Python is just around the corner. With the Python 3.15.0b1 feature freeze, we know what's...
Node.js® is a free, open-source, cross-platform JavaScript runtime environment that lets developers create servers, web apps, command line tools and scripts.
Paul Khuong's personal blog. Some Lisp, some optimisation, mathematical or computer.
Formal verification gates for AI coding loops, in the language you're already shipping.
Over the past year, I’ve been working on fixing C by giving it a high quality, ultra portable standard library. It is not a simple wrapper on top of libc; it doesn’t depend on libc except when required to by the platform. To my knowledge, there is nothing like it.
If you have ever tried to minimize a function with gradient descent, you probably noticed that some functions are a joy to optimize and others are a nightmare. The difference often boils down to two properties: strong convexity and L-smoothness. These two concepts define a “sandwich” of quadratic bounds around your…
Disabling asm.js optimizations in SpiderMonkey
In the past few months, I’ve been stress-testing how far AI coding agents can take us when building real, production-grade distributed systems. The result: a Rust-based multi-Paxos consensus engine that not only implements all the features of Azure’s Replicated State Library (RSL) [1] — which underpins most major…
If he had been a programmer, Cardinal Richelieu would have said “Give me six lines written by the hand of the most expert C programmer in the world, and I wi...
