Got a moment to play Point Galaxy—the newest entry in Flatout Games’ Point games (Point Salad, Point City, and now Point Galaxy)—a couple of nights ago. Quite fun. A bit more complex than Point Salad, but we picked it up fine after a few turns. Can recommend. Cc: @dhinojosa.bsky.social

#SpringSecurity 7 added MFA support docs.spring.io/spring-secur... tldr Add following to require both password and one time token `@EnableGlobalMultiFactorAuthentication(authorities = { GrantedAuthorities.FACTOR_PASSWORD_AUTHORITY, GrantedAuthorities.FACTOR_OTT_AUTHORITY })`

✏️ JEP 8368874 was drafted Title: JEP: Add a JDatePicker UI Component to the Swing UI Toolkit (Preview) Type: feature Component: client / javax.swing See openjdk.org/jeps/8368874

I just upgraded EqualsVerifier and I have to say, the process was extremely painless! I had exactly 1 deprecation to deal with and that was it.

🥲 Me, writing a constructor in #Java before JEP 513: “Fine, I’ll just hack it with inline static method calls.” 👀 😎 Me now: “Validate first. super() later. Done." 🤯 blog.jetbrains.com/idea/2025/09...

Highly-recommended reading: The state of HTTP clients in Spring by Brian Clozel spring.io/blog/2025/09... « This is also a good time to reflect on the state of HTTP clients in Spring, so we will use this opportunity to explain an important announcement: we are officially deprecating RestTemplate. »

Great talk! Looking forward to using it in my projects to replace some awkwardness in my existing projects and get real immutability. #Java

🦆 What the Duck? That’s my talk at #DevoxxBE. Not about Java. Not about frameworks. It’s about the crisis we hide too well in tech. 📍 Oct 7 – 12:40, Room 5 👉 m.devoxx.com/events/dvbe2... #Devoxx #DuckSyndrome #MentalHealthInTech

Woo hoo! Can’t wait to upgrade! #JUnit #Java

I‘m really happy that the #JUnit 6.0 went out today. Thanks to the team for making it happen!

JUnit 6 is here! Ready to upgrade? We’ve got you covered with step-by-step recipes to move from 3 → 4 → 5 → 6. docs.openrewrite.org/recipes/java...

🥂 A huge thank you to @azulsystems.bsky.social for hosting the #dev2next social hour! Speakers & attendees kicked back, connected, and celebrated the start of an amazing conference. Catch a glimpse of the evening ⬇️

Just came across spring.io/blog/2025/0... which says that the Spring Data JDBC 4.0.0 will support composite IDs, which will be awesome for my event-sourced projects! (Currently available to try out with version 4.0.0-M4 or later.) #Spring #SpringDataJdbc #Java #EventSourcing

The #JUnit 6.0 GA Release Notes are almost set in stone. 🗿 docs.junit.org/snapshot/rel... And yeah, there's only like 1 or 2 open tasks for GA. 🤓 Something may be brewing... ☕️

A learning hour is a short training session for a group of software developers. Each one has a specific learning goal - an idea to discuss or a skill to practice. Technical coaches and senior developers can use these as a regular opportunity to level-up their teams: buff.ly/HERzZlb

🚀 Join #dev2next 2025 during September 29 – October 2 for breakthrough developer insights, networking, and innovation. We’re thrilled to announce that Oracle ACEs @brianvermeer.nl , @theguywiththeduketattoo.com , and Rodrigo Graciano will be sharing their expertise as speakers! 🔗 www.dev2next.com

What to do on a fine Sunday? Why not listen to Brian Goetz (and me - sorry, couldn't be helped) about how #Java features are delivered incrementally and how Projects Amber and Valhalla come in feature arcs. 🌠 (Links to some platforms in the next message.)

There's still a bit of work to do, but I've just pushed out a release of my text to speech library with a new phonemizer and initial support for non-english languages. github.com/hcoles/voices #java

@dthompsondev.bsky.social has created an affordable, charitable conference with top tier speakers. He prioritized attendee experience and even got me to play sports! It seems like we successfully bullied him into doing it again, so don't miss next year!

In one of the CITCON sessions yesterday about what we should be teaching software engineers, the notion came up that teaching "A.I."-assisted development wouldn't be grounded in any principles. I'm not so sure about that. A picture's emerging (e.g., clarifying with tests, tight feedback loops etc)

Let the fun begin. All loaded up for @dev2next.bsky.social 2025.

JSpecify and NullAway: A fresh take on nullsafety in the Java world buff.ly/DmeUMJa #Java

TIL: In #Java, List.subList() and List.reversed() are implemented smartly. You may call these methods as many times as you want and in any order, but you don't get a long chain of references which leads to StackOverflowError. The longest chain of views is two: reversed -> subList -> original list.

On the last leg of my journey to Colorado Springs, CO for @dev2next.bsky.social starting Monday. Will I see you there? #Java #EventSourcing #dev2next25

📢 Gatherers4j v0.12.0 is out! - Now built with #Java 25 - Support for modules - Parallelization now supported in UniquelyOccurringGatherer - Several internal organizational and testing changes github.com/tginsberg/ga...

“If you judge people, you have no time to love them."

w00t! Can’t wait to install it for when I resume live coding in a couple of weeks.

One important questions to ask is: "What amount of domain insights are you missing out on by handing off creating the changes to the machine?". Can you quantify that? :) Way more difficult, if not impossible, compared to "saved X hours creating this feature using AI". 1/2

Some updates to my site: ted.dev • Added slides to my talks page for "Testable Architecture" at ted.dev/talks/ • Added the Mob Mentality Show podcast (appearing with John Wilson, and Janis Kampe) to my podcasts page: ted.dev/podcasts/po...

Enjoy my new, artisanal blog post about #JSpecify and #NullAway, a fresh take on null safety in the #Java world. Be warned, may contains #Lombok. Happy weekend you all. info.michael-simons.eu/2025/09/26/j...

🎓 JEP 526 moved to candidate Title: Lazy Constants (Second Preview) Type: feature Component: core / lang See openjdk.org/jeps/526

How often have you temporarily injected a bean 🫘 or added debug code, only to remove it after you find the issue? 👀 With #SpringDebugger, invoke any bean’s methods at a breakpoint and move on. More cases in the video 👇 www.youtube.com/watch?v=kjVy...

I had a chance to play around with first-class API Versioning in Spring Boot 4 this week. This is what I learned 👇🏻 www.danvega.dev/blog/spring-...

As we prepare for the next generation of Spring Boot 4 coming in November it's time to reflect on all of the amazing features that 3.x brought us. What are some of your favorite features?

First time in a while that I've given a talk (a TED TALK as @danvega.dev reminded me!) as short as 25-minutes! Amazingly, it fit exactly and the recording will be available soon at www.commityourcode.com #CommitYourCode Slides are available at ted.dev/talks/

I am excited to speak at @dev2next.bsky.social and to get insights from talks and workshops by industry experts! If you are at dev2next and this drawing gives you the same vibes as the words Enterprise Architecture, join me and we will discuss ways to make architecture more relevant and impactful!

Also, I now have a page explaining the usage of AI (or lack thereof) on my website. verraes.net/ai/ The idea to have it came from the /ai Manifesto, which proposes to have an /ai page "to promote trust and transparency" www.bydamo.la/p/ai-manifesto
