This talk by @briangoetz.bsky.social about Growing the Java Language is one of the best I've seen lately. If you've ever wondered "Why can't they just..." about Java, you should watch this. I hope this talk changes the way I approach growing my own APIs.

As a JUG leader, I sure hope in-person events aren't dying off, but it sure seems like it's getting harder and harder to keep this all going.

this iconic advertising copywriter named Kathy Hepinstall Parks died over the weekend and I wanted to share something from her website I thought Bluesky would like

Why should I write better when a machine can do it for me?
Because actually no one can do it for you, because your voice is unique among all the people on earth. Siri never petted a horse's neck. Alexa has never been ghosted by the captain of the football team. But you have lived, your heart is beating, you have suffered, and you have something important to say. It's a human's job, to use words, and whatever job you give to a machine, that part of your brain goes dark. Maybe it's worth it when it comes to remembering phone numbers and directions, but when that part of your brain that uses words goes dark, that's a vast area that's very close to your soul. Don't let some internet platform convince you that what you have to say and create isn't worthwhile. Words are the echo of your soul. Honing that echo matters.
