The code for which is available on GitHub.While the original repository is fantastic for developers, it also requires a local Python setup, terminal commands, and the installation of geospatial libraries like OSMnx and GDAL – which can be intimidating if you aren’t a coder.I’ve therefore adapted the core logic into a Google Colab Maps Mania… more → Posted in: Interactive Maps Tagged with: Poster
Using Chrome AI to Rewrite Monstrous JSON / / No Comments Happy Saturday folks, and while this is a topic I’ve covered many times here, I was bored and wanting to write some code, so I whipped up a quick demo. One of my favorite uses of AI is to take abstract data and write a human readable form of it. Now to be clear, this is not something you need AI for. Given that you know the shape of your data, you can create your own summary using hard-coded rules about what values to show, how to present them, and so forth. What I like about the Gen AI use-case for this is the amount of randomness and creativity you get in the responses. In the past I’ve done this with weather forecasts and chart data, but today I thought I’d try something... more → Posted in: JavaScript Tagged with: Chrome, JSON, Monstrous, Rewrite, using

Links For You (1/10/26) / / No Comments Happy 2026, programs! As this is the first Links For You for the year, I figure it may be good to remind folks why I write these. Social media can be a great place to share links with folks, but it’s very much hit or miss. Someone may share something incredibly cool that you would love to boost, but if you miss it, you’re out of luck. I subscribe to many listservs that share good tech links, but a while ago I thought it would be cool to share and promote links I thought were especially cool. Obviously that’s pretty opinionated, but that’s why you’re here, right? Each of these posts will have three links, typically but not always tech related, and a fourth entry that... more → Posted in: JavaScript Tagged with: 1/10/26, links
Adding Hardcover.app Data to Eleventy / / No Comments It’s been far too long since I shared an Eleventy tip, and to be fair what I’m showing today can be used anywhere, but hopefully this will be useful to someone else out there. I enjoy tracking my media consumption, specifically movies and books. For movies I’ve been real happy with Letterboxd (you can see my profile if you wish). For books, I used Goodreads for a very long time, but have wanted to migrate off the platform and switch to something else. There’s alternatives, but none really worked well for me. Earlier this week, an old friend of mine (hi Jason!) suggested Hardcover. This is a Goodreads competitor built, in their own words, out of spite, and I can totally... more → Posted in: JavaScript Tagged with: Adding, data, Eleventy, Hardcover.app
