read more ➔Everyone knows the QGIS Plugin Repo but have you had a look at the QGIS Hub yet? It’s similar to the plugin repository in that it allows sharing of resources between community members, but it so many different types of resources, that warrants multiple blog posts: from styles and projects…

read more ➔During a bit of football banter about League 1 over the weekend, Ken said to me “I bet you’ve never been to any of those places either. All a bit far north” – it turned out I had visited 18/24 of the places in the League. That prompted an idea for a geography quiz, could I make a quiz that combined…

Caroline Lea (writing as Caroline Finch) asks an important question - what if every pair of star-cross'd lovers were…

read more ➔LinuxDays 2026, the largest open-source event in Czechia, took place on the first weekend of October, and we had a Fedora & CentOS booth there again. This time, we got a smaller table and our booth equipment was more modest because no one traveled from Brno by car—we only had what we could carry on…
read more ➔No single person can know everything happening in Fedora at any given time. I say this often in our community, half as a warning and half for comfort. For a while, I did not really believe it applied to me. I wanted to know everything. I joined new teams, participated in tickets, and either…
read more ➔Institutions are recalculating who controls the technology they rely on. Mozilla has an independent option to offer. For years, organizations consolidated technology around a small number of providers to make things simpler. Fewer systems. Tighter integrations. More economies of scale. But that…
read more ➔I remember back in 2020, people were complaining that we didn’t have enough documentation for creating GNOME Shell extensions. They said it was almost impossible to figure out where to start. They were right, learning all of it without proper documentation was a huge challenge for me too. So, I…

read more ➔Ports and adapters, also called hexagonal architecture, is the pattern I reach for when a system has rules worth protecting, and the pattern I refuse when it has none. This article is the map between those two cases. If you have read Hexagon of Doom, you know the other half of the argument: on…

Here, I've shortened what Schade uses into one line of CSS (because I can). As noted, this is a fairly new…

read more ➔Developers suck at writing documentation. We like to say RTFM but often there ain't no FM to R. At best we have a half-arsed collection of notes, some obsolete tips, and a link to a desolate forum full of people asking the same questions again and again. That's no way to treat our users. I naïvely…

read more ➔For this post, I wanted to talk about two different approaches to handling supertraits. I’m calling them modular proofs vs external proofs. The key idea of this post is that, if we want to have cyclic trait impls, we really need to use a modular proof strategy, where the impl establishes all…
