Yeah, but has it continuously reminded you that Feb 2 was groundhog day? If not, what the heck are you even paying for, Ken?

RAINMAN! Where you interacted with the compiler by emailing your code to it! Wow that brings back memories.

Week Year: Java Date Formatting With YYYY Instead of yyyy • Todd Ginsberg The end-of-year gotcha lurking in your codebase

It's the time of year when subtle #Java date formatting bugs tend to appear, often caused by using the wrong year format. I’ve written a post explaining what’s going on, how to fix it, and how to prevent it in the future.

I suspect with the Advent of AI my humble effort to solve and explain is not as useful as in years past, but I still have fun doing it.

Growing the Java Language #JVMLS YouTube video by Java

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.

Why Aren't People Going to Local and Regional In-Person Events Anymore? - Brent Ozar Unlimited® Steve Jones recently posted an update about SQL Saturday’s status, and it includes some news we need to talk about: However, this year the number may stagnate or even decline slightly. Running events ...

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.

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.
