#JVM

Smaller object headers = less memory, fewer GC pauses, lower latency. Billy Korando breaks down the JVM trick that boosts performance. #Java #JVM #Performance

Jython 2.7.5 is currently in beta, with a release candidate upcoming soon.
A good moment to test your setup with the upcoming release is *now*!
Mind a breaking change:
Servlet support moves from javax to jakarta namespace.

Java 27 API documentation is now available!
apidia.net/java/OpenJDK...
As usual, we present it in classical style with frame-like navigation.
Another advantage: On APIdia you can also browse internals if you need to.

Java devs, this is YOUR moment. Billy Korando says there's no better way to build generative AI than on the JVM — and the tools are racing to lead. #Java #GenAI #JVM

Next LTS (JDK 29) is going to be a banger 🔥 Value types, AOT compilation (training runs), Adaptive heap sizing, Structured concurrency, Compact object headers. Can't wait! #jvm #jdk

`t.start()` ≠ `t.run()`

`start()` → schedules a new thread
`run()` → normal method call

Java multithreading gets interesting when you add scheduling, shared data, synchronization and thread pools.

I explained it simply 👇

#Java #Multithreading #JVM

Java compiles to Bytecode, which the JVM runs. Early on, this meant slower speeds.

But modern JIT compilation changes everything. The JVM optimizes hot code live for your hardware. For 24/7 backend systems, Java can beat C++ after it warms up.

Stack or Heap? 🤔

`User user = new User();`

Where does `user` go?
Where does the object go?

Understanding Stack vs Heap helps explain:

🔹 GC
🔹 Memory leaks
🔹 StackOverflowError
🔹 OutOfMemoryError

I explained it simply 👇
