Java 26 quietly ships `-Xlog:cpu`, and it’s a perfect match with jbang. Run `jbang --java 26 -R=-Xlog:cpu <yourapp>` to see per-thread CPU stats without attaching a profiler. Handy way to sanity-check GC/VM activity.

Java 26 is here, but it's boring. Nothing really exciting. But that's a good thing, as the boring stability is what made Java successful: mostlynerdless.de/blog/2026/03/1…

Omarchy 3.4 is out! Massive release with 61 contributors, three new themes, tailored Tmux, new screenshot flow, new agent features (claude by default + tmux swarm!), keyboard RGB theme syncing, and a million other things. github.com/basecamp/omarc…

Java 25: an upgrade that saves up to 30% of RAM (without code modifications) In JDK 25, one of the most significant optimizations in a long time was introduced - Compact Object Headers (JEP 519). What changes: - The size of the object header is reduced from approximately ~12 bytes to 8 bytes - Less memory per object = less heap - Less heap = less pressure on the GC - Less GC = faster service + cheaper cloud Where the benefit is maximum: Spring Boot, microservices, DTOs, records, caches - everything where there are a lot of small objects. It's enabled with one option: -XX:+UseCompactObjectHeaders According to reviews in real systems: A 15–30% reduction in heap is a common occurrence. Just test it on your own services - and reap the free savings.

JDK 26: Structured Concurrency Hits Sixth Preview – Safer, Simpler Concurrent Code: JDK 26 advances Structured Concurrency to its sixth preview in JEP 525. This powerful API treats groups of related tasks as a single unit of work: spawn subtasks with StructuredTaskScope, await completion cleanly, handle errors/shutdowns automatically, and avoid leaks or orphaned threads. Key refinements include better timeout handling, custom join policies, and improved observability. It's ideal for parallel processing in web services, data pipelines, or AI workflows far safer than raw threads or ExecutorServices. Enable it with --enable-preview and import jdk.incubator.concurrent.*.

📣 Woohoo! A proper real #TUI library for #java!!!! Big Day! Congrats Cédric and @maxandersen 🥳

Kimi K2.5 on @opencode Zen is hilariously cheap. I bought $20 worth of tokens two weeks ago, and I still have $10.89 left! After 3M tokens! If there's a bubble in AI, it's pricing a million tokens at $25 (and beyond).

Apache Kafka 4.2.0 is about to drop any minute now! 🔥 A heavy release, it introduces close to 32,000 new lines of Java. What comes with all that code? Here's everything you should know about it: 1/8 🧵

As promised, you can expect ongoing updates on my book "Hands-On Java with Kubernetes". This time, update to the latest versions of tools and frameworks from examples: 🔹Java 25 🔹Spring Boot 4.0 🔹Quarkus 3.31 🔹Kubernetes 1.35 Grab while it's hot🔥 leanpub.com/hands-on-java-…

Great to see @jetbrains get serious about Wayland. Their suite of IDEs have been made to work in Omarchy with a plethora of window rules and hacks, but would be great if everything was just right out of the box. So excited to see this! alternativeto.net/news/2026/2/je…

Wow. MySQL hasn’t had a repo commit in 3 months since Oracle laid off a bunch of people? Maybe this is why some MySQL cloud service companies are now offering Postgres. There’s some really big companies who have MySQL as their backend.

On 1 Dec 2020, AWS S3 announced that all writes to S3 are now strongly consistent (not eventually consistent, like before) *at no price change or latency changes* to any customers. Pulling this off was probably one of the biggest invisible engineering achievements of the decade
