Fascinating (this week) — a handful of things that caught my attention.
https://fascination.works/fascinating/2026/03/17/fascinating-this-week/
This year marks the 20th anniversary of my work on JRuby! I'm looking forward to sharing that story and talking about the future with folks around the world. Being able to speak at @RubyConf and @RailsWorld would be a fitting way to celebrate 20 years. I hope I'm accepted. 🤞
TFW you delete almost 1000 deprecated methods, fields, and classes that have accumulated over the past 20 years. Oldest one deprecated in JRuby 1.1.2, released back in 2008.
I'm sure we will find third-party libs using some of these, but we'll never know until we delete them.

Trying out Mastodon blog comments: I wrote about Monitoring a Kamal Deployment with Prometheus a couple of weeks back.

Craig S. KaplanIn my online undergraduate P5.js course, students are about to begin the module on motion and physics, including a bit of physics simulation using Matter.js. It suddenly occurred to me that I had never seen anybody put together this particular demo before, and I realized it had to be done. Messy source code at https://editor.p5js.org/isohedral/full/vJa5RiZWs.
JRuby 10.1 with Ruby 4.0 support is now the master branch and it's GREEN! 10.1 snapshots are already in the Sonatype snapshots repo and as "jruby-head" for Ruby installers and the setup-ruby GHA action. Docker Hub dev images will be available soon. Get in there and test it out!

TuriA couple of months ago a family friend had a very serious health issue and he couldn't move or speak much. So I put together a web app with a set of phrases, connected to a game controller, in a way that he could just select phrases from the list to communicate. Luckily this person got better quickly, and this app was no longer needed, but I decided to improve this experiment and publish it as an Open Source project.
So, this is VoxEase. It can be operated with a mouse, a touch screen, a computer keyboard, a game controller using a single hand, or you can set it to scan the list of phrases automatically so you only need to press one button to pick your phrase.
It only requires a modern browser and once downloaded it works offline.
It supports multiple languages and it can also be used by people with sight impairments (it works with screen readers).
Any suggestions on how to make it better are welcome!
