I am now generating this website with Clojure (yes, right after rewriting it in GNU Make and shell ; I have a problem, ok?). In a personal tradition, I used writing a static site generator as the project to play with and learn Clojure as a new language. While I’ve long scoffed at Clojure for its copious syntax ( three…
News post: Gleam v1.19.0 released!
Someone on Reddit recently asked: What would make a Rust implementation of something faster than a C implementation, all things being the same? I think this is…
News flash: C++26 is done! 🎉 On Saturday, the ISO C++ committee completed technical work on C++26 in (partly) sunny London Croydon, UK. We resolved the remaining international comments on the C++26…
Fortran : High-performance parallel programming language
I’m happy to announce that RISC-V platforms are now officially supported by CPython. 🎉 🚀
Tcl/Tk 9.1.0 is the current development work on Tcl and Tk, aiming toward stable releases in September 2026. They add new features and interfaces to the foundation of Tcl/Tk 9.0.
I have been told that when proposing to formalise mathematics these days, you have to explain why you are not using Lean. And that reminds me why I left the dependent-typed world 40 years ago: its cultism, insularity and conformity. Lean is a great language with good tools, a large library and a huge, enthusiastic…
Go 1.27 includes a change to the HTTP client that can make programs sending many sequential HTTP/1 requests significantly faster.
just a diary
I built KillSwitch, an esoteric language designed to confound LLMs and coding agents, and benchmarked the major models against it.
Demonstrating the basics of logic programming with data from the Pokémon games.
What Zig felt like, coming from Rust Intro I’ve spent the last 7 years as a Rust developer, working mostly on open source projects, and I’d like to think I’ve built a solid feel for the language and its ecosystem along the way. I gravitate toward the functional side of Rust like clean functions, expressive types, that…
In Why Lean is Faster Than Rust , the author shares an impressive result: a DEFLATE compression library written in Lean 4 , a functional programming language and proof assistant, outperforming an equivalent Rust package that crates.io says has been downloaded over a billion times. From the article:
I had a friend tell me recently that all programming languages seem very similar to each other. They all have variables, and arrays, a few loop constructs, functions, and some arithmetic constructs. Sure, some languages have fancier features like first-class functions or coroutines, but he doesn't consider himself an…
Zig is a general-purpose programming language and toolchain for maintaining robust , optimal , and reusable software.
Java 26 is here, and its main purpose seems to be to provide a solid foundation for future things to come. It comes with a few new features, some performance improvements and multiple enhancements that mention Project Valhalla as the inspiration for their existence. This post has all the info!
New SBCL versions are usually released at the end of each month: check the Sourceforge File List to see the current version. The new features of all SBCL releases are listed below.
Pharo is a pure object-oriented programming language and a powerful environment focused on simplicity and immediate feedback.
I don’t think I’ve ever quite articulated my “grand vision” for Rust, despite having written a fair bit about the language and its features. There is a lot I could say here, but currently there are three directions of development which I find particularly interesting:
As a member of the Zig core team, one of the most impactful projects I’ve been involved with is the implementation of incremental compilation into the Zig compiler. This feature allows the compiler to detect which individual functions and declarations have changed since a project was last built, recompile only that…
Highlights of the Julia 1.13 release.
i found yet another way to invoke arbitrary functions in javascript without using parentheses
Scheme (and Lisp) lets you express complex systems and problem domains in simpler terms than any other language can. For all its brilliance, Haskell resists most of the attempts people make to just hack and write useful code quickly.
WhatsApp has adopted and rolled out a new layer of security for users – built with Rust – as part of its effort to harden defenses against malware threats. WhatsApp’s experience creating and distri…
I got asked a good question today: what is the difference between Tree-sitter and a language server ? I don’t understand how either of these tools work in depth, so I’m just going to explain from an observable , pragmatic point of view.
About a year ago I posted about defer and that it would be available for everyone using gcc and/or clang soon. So it is probably time for an update. Two things have happened in the mean time: A tec…
