Using the repair-friendly Framework 13 laptop chassis, I've tested the low-end x86 option (a Ryzen AI 5 340 Mainboard), the fastest RISC-V option (DC-ROMA II), and today I'm publishing results from the only Arm Mainboard, the MetaComputing AI PC, which has a 12-core Arm SoC and up to 32 GB of…

Last year my aunt let me add her original Tangerine iBook G3 clamshell to my collection of old Macs1. It came with an AirPort card—a $99 add-on Apple made that ushered in the Wi-Fi era. The iBook G3 was the first consumer laptop with built-in Wi-Fi antennas, and by <ar the cheapest way to get a…

I've got a new homeserver/NAS (Network Attached Storage), previously I was using some Raspberry Pis, but I've wanted for a while a low power board that has SATA ports for attaching hard drives and one that could run GNU Guix, and the ZimaBoard 2 looked like it might be a good option.

A step-by-step tutorial on detecting clouds and cloud shadows from satellite imagery using OmniCloudMask and GeoAI, with post-processing, vectorization, and cloud-free mask generation.

I always spend too much time setting up a new project and thinking how to structure it. I decided to summuraize my experience, to enhance it with a small research and to write down my thoughts on the topic. So I can come back to it myself or reference in the discussion.

Hello! My big takeaway from last month’s musings about man pages was that examples in man pages are really great, so I worked on adding (or improving) examples to two of my favourite tools’ man pages. Here they are: the dig man page (now with examples) the tcpdump man page examples (this one is an…

A step-by-step tutorial on creating an interactive spinning 3D globe with raster and vector data overlays using a web-based tool or Jupyter Notebook, no coding required.

Fifteen months have passed since our last Guix/Hurd on a Thinkpad X60 post and a lot has happened with respect to the Hurd.

Announcing GeoAI QGIS Plugin v1.0 with one-click installation, SAM 3, water segmentation, forest segmentation, and export to vector, raster, COCO, YOLO, and Pascal VOC formats.

A cool thing about Guix (and probably functional package managers in general) is, that derivations form a directed acyclic graph, which means that all packages with their dependencies or system configurations can be represented as such. Another, even cooler, thing is, that Guix provides a graphing…

I've raised a few PRs against the Guix Codeberg repository recently, and each time I've done so with Forgejo's AGit workflow. This workflow is pretty nice, and allows me to raise a PR entirely from within Emacs. To do that, I've been using this code in my Emacs config to add an extra option to the…

Hello! After spending some time working on the Git man pages last year, I’ve been thinking a little more about what makes a good man page. I’ve spent a lot of time writing cheat sheets for tools (tcpdump, git, dig, etc) which have a man page as their primary documentation. This is because I…
