The theory versus the practice of “static websites”
You're probably reading this page because you've attempted to access some part of my blog (Wandering Thoughts) or CSpace , the wiki thing it's part of. Unfortunately you're using a browser version that my anti-crawler precautions consider suspicious, most often because it's too old (most often this applies to versions…

Even if you can't write assembly, you can read disassembly
This is a very concise introduction to x86 disassembly. It shows that you probably have all the skills to start reading disassembly right now even if you thought it was too complicated for you. It really isn't, see it for yourself.

When LIMIT 9 works but LIMIT 10 hangs
I got a Slack message from colleagues at a major partner. They’d updated their dev environment to support WebSockets, so that Neon’s serverless driver could be used there, but then they’d run into a weird issue. The nub of it was this: This hangs: This works Reproducibly, the query without an ORDER BY ran fine […]

Io uring
Introduced in 2019 (kernel 5.1) by Jens Axboe, io_uring (henceforth uring) is a system for providing the kernel with a schedule of system calls, and receiving the results as they're generated. Whereas epoll and kqueue support multiplexing, where you're told when you can usefully perform a system call using some set of…

A decade of developing a programming language
In 2013, I had an idea: "what if I were to build my programming language?". Back then my idea came down to "an interpreted language that mixes elements from Ruby and Smalltalk", and not much more.

Arena allocator tips and tricks
Over the past year I’ve refined my approach to arena allocation . With practice, it’s effective, simple, and fast; typically as easy to use as garbage collection but without the costs. Depending on need, an allocator can weigh just 7–25 lines of code — perfect when lacking a runtime . With the core details of my own…

Running the "Reflections on Trusting Trust" Compiler
Supply chain security is a hot topic today, but it is a very old problem. In October 1983, 40 years ago this week, Ken Thompson chose supply chain security as the topic for his Turing award lecture, although the specific term wasn’t used back then. (The field of computer science was still young and small enough that…

I kind of killed Mercurial at Mozilla
Did you hear the news? Firefox development is moving from Mercurial to Git . While the decision is far from being mine, and I was barely involved in the small incremental changes that ultimately led to this decision, I feel I have to take at least some responsibility. And if you are one of those who would rather use…

LLM Powered Autonomous Agents
Building agents with LLM (large language model) as its core controller is a cool concept. Several proof-of-concepts demos, such as AutoGPT, GPT-Engineer and BabyAGI, serve as inspiring examples. The potentiality of LLM extends beyond generating well-written copies, stories, essays and programs; it can be framed as a…

The curl-wget Venn diagram
In my view, wget is not a curl competitor. It is a companion tool that has a feature overlap with curl. Use the tool that does the job. Getting the job done is the key. If that means using wget instead of curl, then that is good and I don't mind. Why would I? To … Continue reading The curl-wget Venn diagram →

Flattening ASTs and other compiler data structures
This is an introduction to data structure flattening, a special case of arena allocation that is a good fit for programming language implementations. We build a simple interpreter twice, the normal way and the flat way, and show that some fairly mechanical code changes can give you a 2.4× speedup.

Low Code Software Development Is a Lie
I’ve been writing custom software for a long time and one of the things that annoys me most is when a client adopts the position that there is a silver bullet which will reduce or remove the inherent complexity of this task. This happens more often than you’d think and guess what? They are almost always wrong. Perhaps…
