In a zero-copy runtime designed for 1-VT-per-Stream density, ThreadLocal is a performance serial killer. Here is the forensic analysis and how JEP 506 Scoped Values changed everything. When I started designing the Exeris Kernel — a next-generation, zero-copy runtime built for Java 26+ — I established one non-negotiable architectural law: "No Waste Compute." In a…...

Happy to announce I started writing my next book: Crafting Spring Boot Starters.

You will learn how the best Spring Boot 4 starters get written, the ones that just feel idiomatic when you drop them in. 30+ chapters, patterns from real production libraries built from scratch.

I’m not only presenting two talks (one is a game, guess what it is), but also thrilled to do a workshop on my current passion: #EventSourcing and #DomainDrivenDesign #Java

I just sponsored Namastack for the Outbox Pattern. Join me and sponsor your open source dependencies!

So, #Intellij just autocreated an empty method for
ticketReissueRepository.findByTicketPurchase_Order_IdOrderByReissueDateDesc(int) via guided autocomplete in this (not quite #SpringBoot) system and... I'm a little conflicted

Obviously it Just Worked (and if it hadn't it would have failed immediately at runtime rather than lurking until called), and writing JPA was never something that got me up in the mornings, but... If this is The Pattern, there is a lot of code to refactor

Flaky GitHub Pull Request builds are an annoying reality in many projects. Just when you think a change is complete and good to merge, you are greeted with an ❌. To unblock your PR, you need to rerun lengthy test pipeline just because of one rogue test.

If you have a Java project on GitHub, TestLens can help you:

Drop me a message, if you would like to join or beta program.

TestLens control buttons in a comment on your GitHub Pull Request. They offer a 'Only rerun the tests that failed or were muted before' checkbox to activate before triggering a rerun through the 'Rerun job' checkbox.

Great series of articles about Ecotone, a PHP #EventSourcing library (framework?), and this one about projections was nice to read as it confirms my current implementation (and/or design) in my ES library for #Java.
