Java Concurrency With Project Loom

Early Access: Java Concurrency With Project Loom

I am excited about Project Loom. The project focuses on easy to use lightweight concurrency for the JavaVM. Nowadays, the JavaVM provides a one java thread to one OS thread model to the programmer. While it's actually the current Oracle implementation, it used to be that many JavaVM versions ago, threads provided to the programmer were actually green threads.

Project Loom goes down that road again, providing lightweight threads to the programmer. Those lightweight threads are mapped to OS threads in a "many-to-many" relationship.

Write Your Own Imaging Processing UI in 15 Minutes, Using Kotlin and Compose for Desktop

Compose used to be just a smooth way of writing Android Applications in Kotlin. Now JetBrains has ported Compose to the Desktop, and it's now easier than ever to prototype UI in real-time. 

Of course, you can write a web app-based UI or a single-page application, but sometimes, especially in the IoT world, and a small cluster of Raspberry Pis, the easiest way is to have actually a small Desktop UI.

Raspberry Pi, OpenCV, Deep Neural Networks, and — Of Course— a Bit of Clojure

Learn more about Raspberry Pi, OpenCV, deep neural networks, and Clojure.

I had to write a simple IoT prototype recently that counted the number of people in a queue in real-time. Of course, I could have hired someone to do that and just keep counting people, or ... I could write a program in Clojure using a Raspberry Pi to detect the number of heads via a video stream.

We learned recently that when using inlein, you can easily write scripts in Clojure with dependencies and run them just about anywhere, at a quite decent speed.
