Tinker Tuesday for May 19th, 2026

This thread is for anyone working on personal projects to share their progress, and hold themselves somewhat accountable to a group of peers.

Post your project, your progress from last week, and what you hope to accomplish this week.

If you want to be pinged with a reminder asking about your project, let me know, and I'll harass you each week until you cancel the service.

Per @ToaKraka's suggestion, I've built a fairly snazzy-looking map in QGIS. What I'd now like to do is export it to HTML so that senior management can peruse it at their leisure without having to install QGIS. When you open the link, it should show you a map of my country broken down into counties, with scale-based rendering applied so that, when you zoom in, the county boundaries disappear and are replaced with electoral boundaries. Clicking on any electoral district should produce a pop-up listing key metrics (population, population density, average age etc.). There should also be several layers that you can toggle on and off visually representing e.g. average age by electoral district.

Someone is bound to suggest exporting to qgis2web. I have tried this, and while it works perfectly when zoomed all the way in, panning and zooming are unforgivably slow when zoomed out to the national level. ChatGPT and Gemini have suggested several ways to improve performance (dramatically simplifying my vector layers, exporting to vector tiles, customising the JavaScript produced by qgis2web), with limited success. One or the other also suggested exporting to raster tiles, and in fairness the panning and zooming are as smooth and fast as I'd like. On the other hand, the export files are half a gigabyte, and that's only including 2 of my desired 11 layers. This seems preposterously large for a 2-dimensional map of a small island.

Anyone with any experience in GIS have any resources on how to produce a lightweight, high-performance webmap, ideally for someone with limited coding experience?

What is this place?

This website is a place for people who want to move past shady thinking and test their ideas in a court of people who don't all share the same biases. Our goal is to optimize for light, not heat; this is a group effort, and all commentators are asked to do their part.

The weekly Culture War threads host the most controversial topics and are the most visible aspect of The Motte. However, many other topics are appropriate here. We encourage people to post anything related to science, politics, or philosophy; if in doubt, post!

Check out The Vault for an archive of old quality posts. You are encouraged to crosspost these elsewhere.


Why are you called The Motte?

A motte is a stone keep on a raised earthwork common in early medieval fortifications. More pertinently, it's an element in a rhetorical move called a "Motte-and-Bailey", originally identified by philosopher Nicholas Shackel. It describes the tendency in discourse for people to move from a controversial but high value claim to a defensible but less exciting one upon any resistance to the former. He likens this to the medieval fortification, where a desirable land (the bailey) is abandoned when in danger for the more easily defended motte. In Shackel's words, "The Motte represents the defensible but undesired propositions to which one retreats when hard pressed."

On The Motte, always attempt to remain inside your defensible territory, even if you are not being pressed.


New post guidelines

If you're posting something that isn't related to the culture war, we encourage you to post a thread for it. A submission statement is highly appreciated, but isn't necessary for text posts or links to largely-text posts such as blogs or news articles; if we're unsure of the value of your post, we might remove it until you add a submission statement. A submission statement is required for non-text sources (videos, podcasts, images).

Culture war posts go in the culture war thread; all links must either include a submission statement or significant commentary. Bare links without those will be removed.

If in doubt, please post it!
