Working Group 2 is pleased to announce the first draft of the second part of the R7RS-Large Foundations, the Procedural Fascicle". This draft encompasses the familiar block programming forms, such as lambda, let, if, or, and set!. The draft is…

Shhhh! This post is only available to RSS subscribers like you 😊 My wife and I are preparing for a big Interrail journey through Europe. Whenever we go on holiday, we like to meet up with friendly locals to have a drink and chat. We did this on our last journey and it was great. So, if you're a…

At NAB, I found a demo of Wi-Wi STAMP, a wireless time synchronization protocol that came out of Japan's NICT. Wi-Wi stands for Wireless 2Way interferometry, and it uses the 900 MHz band for picosecond-level time sync, and mm-level distance accuracy, in a tiny box, currently the size of a…

What's better than one Adrian Tchaikovsky novella? Three Adrian Tchaikovsky novellæ! Or is it "novellii"? Either way, a delightful triptych of stories on a common theme. On the surface, they're about travelling to a new destination (Space! The Future! For-Copyright-Reasons Not Narnia!) Except,…

SRFI 273 is now in draft status. The original SRFI 253 established a basis for type-checked (or otherwise checked) data handling. But it lacked some quality-of-life features. This SRFI extends SRFI 253 to match existing implementation practice and common sense. Provided extensions are: check…

Within the UK's Civil Service you occasionally hear the expression "being invited to a meeting without biscuits". It implies a rather frosty discussion without any of the polite niceties of a normal meeting. In general though, even when people have severe disagreements, it is rare for tempers to…

Last year I went through a self-hosting spree during which I deployed some services (e.g. Nextcloud, Mattermost, and Prosody) to a bunch of VPSes, while documenting the process on this blog. This post is a follow-up on that series, detailing the deployment of GoToSocial, a lightweight ActivityPub…

The UK Government, for all its faults, is pretty good at publishing contracts it has awarded. That's why I get depressed when I see rage-bait nonsense about how companies have been award "Top Secret" deals. Right now you can go to https://www.contractsfinder.service.gov.uk and search for whichever…

Hello! 8 years ago, I wrote excitedly about discovering Tailwind. At that time I really had no idea how to structure my CSS code and given the choice between a pile of complete chaos and Tailwind, I was really happy to choose Tailwind. It helped me make a lot of tiny sites! I spent the last week or…

SRFI 272 is now in draft status. This SRFI follows the traditional Scheme model of pretty printing, which treats it as a process distinct from general controlled formatting. While general-purpose formatters often prioritize specialized presentation at the expense of machine-readability,…

We are excited to announce the release of Hoot 0.9.0! Hoot is a Scheme to WebAssembly compiler backend for Guile, as well as a general purpose WebAssembly toolchain. In other words, Scheme in the browser! This release contains new features and bug fixes and since the 0.8.0 release back in…

By Greg Stein, Apache Software Foundation Member and STeVe Contributor Every year, roughly 800 members of the Apache® Software Foundation cast votes to elect a Board of Directors, admit new members, and decide the direction of one of the oldest and most important institutions in open source. No…

Last year I said I'd probably never recommend another Bambu Lab printer again. I still use my P1S, but after Bambu Lab started pushing their always-connected cloud solution as the new default: I blocked the printer from the Internet via my OPNsense Firewall I stopped updating the firmware I locked…

A tutorial on searching, streaming, visualizing, and downloading NASA Earth observation data inside QGIS using the NASA Earthdata plugin and OpenGeoAgent for natural-language and voice workflows.

A tutorial on using OpenGeoAgent with the QGIS Timelapse plugin to generate Landsat, MODIS, GOES, and Esri Wayback timelapse animations from natural language and voice prompts.

Here’s a comparison between the three pixel/​sprite/​tile making apps I could find on F-Droid. I know there’s stuff in that vein on Varvara, but I haven’t figured out a good way to run Varvara apps on Android yet, especially in a way where I could get files in and out. (Definitively still interested…

Apple introduced the HomePod mini six years ago, in 2020. I'm not one into smart speakers, but the feature that made me take a closer look was their ability to form stereo pairs, without any direct wired connection. I know there are other speaker manufacturers with wireless speakers, but to my…

The schedule for Community Over Code Glasgow 2026 is live, with an expansive program: 168 sessions across 18 tracks, spanning four days in October. Whether you’re running infrastructure at hyperscale, modernizing a fintech stack, or trying to figure out what responsible AI governance actually looks…

While Guile Scheme has a lot of hidden gems, like (ice-9 peg), parsing command line arguments is not one of its strengths in my opinion. Even if there are many powerful approaches to structured argument parsing, there is no API simple enough for me to know it by heart (as opposed for example to…

Catching air in the middle of the deep-dive on Scheme bytecode interpreters.

Part I explains why Apache Geode 2.0 matters. Part II walks through how it was modernized. Stay…

How I did my part in saving the planet by getting an old but working audio interface up, running and mainlined in GNU Guix. Read the whole post here.

A step-by-step tutorial on installing the NASA OPERA QGIS plugin, searching and visualizing DSWx surface water products, and using an integrated AI agent to analyze flood events with natural language and voice commands.

Guix will be featured at the annual conference of the French Reproducible Research Network, 19–21 May 2026, Bordeaux, France.
