Apache® Livy, a REST service for Apache Spark™, becomes a Top-Level Project Wilmington, DE –  June 4, 2026 – The Apache Software Foundation (ASF), the global home of open source software the world relies on, today announced that Apachy Livy has become a Top-Level Project (TLP).  Apache Livy is…

My nephew just graduated high school, and wants a laptop. When he decides what computer to buy, price (or more precisely, value) is the most important attribute. Apple's MacBook Neo upended the 'value laptop' equation—Apple's not supposed to be both the cheapest option <nd the best value... but it…

From the rise of Apache Iceberg and the modernization of Apache Geode, to a behind-the-scenes look at the rebuild of Apache STeVe v3, this month’s Plus One highlights how open collaboration continues driving innovation across the ASF ecosystem. We’re also gearing up for Community Over Code Glasgow…

Pooch from Repkord dropped by my studio while he was in St. Louis, and asked a simple question: Can a 3D printer's heatbed act as an antenna? A fair question, as many an antenna is embedded in a PCB these days... and the traces on a PCB heatbed like the one used in Prusa's Core One look kinda like…

A tutorial on accessing, streaming, downloading, and analyzing Planet Tanager 426-band hyperspectral imagery in QGIS using the HyperCoast plugin, including footprint browsing, HDF5 downloads, custom band composites, and spectral signature inspection.

A tutorial on accessing, visualizing, and analyzing NASA Harmonized Landsat Sentinel-2 (HLS) imagery in QGIS using the NASA Earthdata, GEE Data Catalogs, and OpenGeoAgent plugins, including RGB composites, NDVI, monthly time series, pixel extraction, and voice-driven workflows.

On Thursday, three of the lead Raspberry Pi engineers hosted an AMA on the r/engineering subreddit. Raspberry Pi 6 One of the most interesting tidbits was on the Pi 6. Looking back at previous launches: 2012: Raspberry Pi 2015: Raspberry Pi 2 (+3 years) 2016: Raspberry Pi 3 (+1 year) 2019:…

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…

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…

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…

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.

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…

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.

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.

A while back I decided to stop using Tailwind for new projects and to just write vanilla CSS instead. But one thing I missed about Tailwind was the colour palette (here as CSS). If I wanted a light blue I could just use blue-100 and if I didn’t like it maybe try blue-200 or blue-50. I’m not very…

Introducing OpenGeoAgent, an open-source multimodal AI agent that automates geospatial analysis and visualization in QGIS through natural language and voice commands.

Hello! One of my long term projects on here is figuring out how to write frontend Javascript without using Node or any other server JS runtime. One issue I run into a lot in my frontend JS projects is that I don’t know how to write tests for them. I’ve tried to use Playwright in the past, but it…

Pictured above is the new DeskPi Super4C installed in an 8U mini rack. The Super4C is a 4-node Raspberry Pi CM5 cluster board that solves two pain points I had with the older Super6C. I was testing this board around the same time I helped kick off the SBCC 2026, the Single Board Cluster Competition…

Support for remote controlling Windows PCs may be added to Raspberry Pi Connect, Raspberry Pi's free remote access service. When they announced Pi Connect in 2024, I speculated the service was launched in response to RealVNC's sluggish adoption of Wayland, leading to Pi users lacking a solid…
