The title says it all. I've got two Apple laptops. I've got an iPhone and an iPad and a Watch. The "oldest" laptop is from 2024. Not that old, I know, but in the intervening years I've changed the email associated with my Apple ID. Apparently their systems for contacts propagation (e.g., my list of phone numbers) rely on the old username being the same as the new one. (Why?) So I was getting text messages on the older Mac from people whose names weren't showing up. They showed up correctly on all the devices signed into the same Apple account using the new username (the newer email). Just not here. So I was getting the messages, but the contacts weren't syncing. I tried the usual: System Settings -> iCloud -> toggle Contacts. Nothing.

I've been struggling with the most frustrating random configuration setting in IntelliJ IDEA ever.

I marked sixteen years on the Spring team this August! What an amazing time to be alive.

Sigh. SDKMAN.io has gone from being one of my favorite tools to being this never ending disappointment. What process could result in buildings taking this long to show up? It sometimes lags days behind a given JDK's release. Case in point, one OpenJDK distriution, GraalVM, has been available for days but is still not available in SDKMAN. So, while we wait. Here's how you can install the JDK on your own system. I'm assuming you're using macOS.

The folks at CultRepo, the studio that put, among other things, the amazing Kubernetes documentary and countless others, has just put out a documentary on Jetbrains (and my favorite IDE, IntellIJ IDEA) and I had the great privilege of being in it!

When building modern search functionality, developers often reach for specialized search engines like Elasticsearch or Solr. But what if you could build a sophisticated, production-grade search engine using just JDBC and PostgreSQL? This article explores a fascinating implementation that combines vector embeddings, full-text search, and fuzzy matching—all powered by PostgreSQL's rich ecosystem of extensions.

Happy new year! I just wanted to write a quick post about how to solve a problem that vexxed me for hours and I know I'll need again at some point: how to use a SQL array with Spring Framework's JdbcClient.

Hi! It's Christmas as I write this and in many parts of the world and to those of you who celebrate, let me wish you a very merry Christmas indeed!

I love Spring Security so much.

I just got back from Malmö, Sweden, where I spoke at the amazing ØREDEV conference. I love that show! I'ves spoken there various times over the years, including waaaay back in 2013 where I had the pleasure of meeting XKCD creator Randall Munroe.

I just spent a bit too long trying to figure out how to script my Java scripts. I wanted to go as far as giving them a shebang line, but if I created a file called hello.java and put the following in

Let me start by saying: I just think this is really cool. It's not official or anything. Just super cool and only amounts to a few dozen lines of Java code that you could write yourself.
