I've just published a small library that allows you to write #JUnit5 parameterized tests in a human-readable way. Just provide a format and use it to define your test cases 👇 https://t.co/SH61CpRFuH
JDK 27 reaches general availability on September 14. Two of its JEPs change your memory footprint and GC behavior with zero code change. A third headline feature is entering its twelfth incubation. Telling those two groups apart is the actual senior-dev read.

#Java + #Kubernetes quirk: if you remove CPU limits to avoid throttling, the #JVM may suddenly think it can use all CPUs on the node, which can mean dozens of extra threads (GC, JIT, ForkJoinPool...) 🤯
Luckily, there’s a way to address that 👇 https://t.co/JWI8ZlF0H2
My 'Awesome lost & found' collection is back!

This is interesting! Not only for containers, it also allows spawning lightweight virtual machines 👀
And it being OSS adds to the news 🔥
We are working on a new big project for @GraalVM — Project Crema: https://t.co/4YwBr8GkVS.
It will lift Native Image's default closed-world assumption by allowing dynamic loading and execution of classes at run time.
Stay tuned for updates!
How ZGC efficiently allocates memory and balances physical memory mapping to minimize overall runtime memory usage. While assessing memory usage, you may want to look at how good the GC is at reclaiming unused memory to the OS.

Happy 10th birthday (counted from the first public commit on GitHub) to @testcontainers 🥳🍰
Thank you for changing our lives in many, sometimes unexpected ways ☺️

I don't remember being so excited about some of my past articles becoming obsolete! https://t.co/LV6FsUvj4T
Blogged: Restrict Mutability of State
"Much code that we consider complex is considered complex because of the mental highwire act we perform when trying to understand what (the hell) is going on. Thinking about code should not be a circus performance."

Making a bigger impact without working more? Last year, I discovered that it's not only possible but also effective. It was a year of scaling myself. https://t.co/DBJnEi9oB1
