Open a Unix or Linux terminal emulator. If you have Terminal.app on macOS, ensure that the "Use Option as Meta Key" option is enabled in its "Preferences" section. Now type foo bar baz followed by meta + b (i.e. alt + b or option + b on modern keyboards). In a typical desktop environment with a typical and modern…
Write your first hypervisor from scratch, in 1K LoC.
For me, the best way to understand something is usually to implement it myself. So when I first started getting serious about Haskell, I implemented (in Common Lisp) a simple lazy functional programming language that used graph rewriting for the interpretation. Then, years later, I mentioned this implementation in a…
These koans have been independently translated into Chinese (archived) , thanks to Wanzhang Sheng, and into Spanish (archived) , thanks to Daniel Campoverde Carrión.
This article is one chapter of my master thesis entitled “Design and implementation of a graphical user interface for git”. It describes the algorithm I designed to draw the commit graph in my own prototype git client called gitamine. I have adapted the content so that it fits better with this blog. Drawing graphs is…
This is the second part in a series on WebAssembly and what makes it fast. If you haven’t read the others, we recommend starting from the beginning. JavaScript started out ...
Few weeks ago a bug was filed against Dart SDK citing "very low performance of String.substring " . Here is a core of microbenchmark developer submitted together with the issue:
pyscript.net Supporting open source and creating tools that enable people to do more with less are why I joined Anaconda almost eight years ago. Today,…
How low we can Go and still do something useful? I recently bought this ridiculously cheap board: I bought it for three reasons. First, I have never dealt (as a programmer) with STM32F0 series. Second, the STM32F10x series is getting old. MCUs belonging to the STM32F0 family are just as cheap if not cheaper and has…
I’ve done a couple of posts on LLVM itself, mostly on things you can do with LLVM or how LLVM represents particular program features.
Today, as I announced earlier, the Corman Lisp 3.1 has been released after more than a decade-long break. Somehow it happened that I am one of the active mai...
Zig lets you run code during compilation. What are the implications?
Realtime rendering and videogame programming mostly, but I love computer science and visuals in all their forms. This is a notepad of my ideas.
This post was part of an experiment. It was largely generated by AI, and does not reflect my views. Please see the post How I Tricked Hacker News and Made The Front Page with AI Slop for details! The

You are seeing this because the administrator of this website has set up Anubis to protect the server against the scourge of AI companies aggressively scraping websites . This can and does cause downtime for the websites, which makes their resources inaccessible for everyone.
The library for web and native user interfaces
Qt 6.4 is now available and comes with a lot of new modules, features, and improvements. And Web Assembly is now a fully supported platform!
But OCaml is Pretty Great
In my previous post, I mentioned that have serious issues with the current Modules TS as it is written. I have wanted to say more on the subject since my tweets, posts, and general comments are missing quite a bit of context for why I think the implementation is wrong and will be more trouble than it is worth.
One of the (many) depressing things about the "AI" future in which we're living, is that it exposes just how many people are willing to outsource their critical thinking. Brute force is preferred to thinking about how to efficiently tackle a problem. For some reason, my websites are regularly targetted by "scrapers"…
Let's assume Go has one killer feature – cheap concurrency – not present in any other language with similar serial performance (ruling out say Erlang). And let's agree that it gives Go its perfect niche – and we're only discussing uses of Go outside that niche from now on. So we won't come back to concurrency till the…
Not just `#[derive(Clone)]`, but all of the standard trait derives are
