Several tips and tricks for the Linux operating system, together with some useful links – not only for desktop and laptop installations, but also for the Raspberry&npsp;Pi. Some stuff is useful even for the Mac.
Information about the Raspberry&npsp;Pi, projects based on that computer and related stuff.
The Arduino and alike
This section is under construction … ok, nothing here yet.
Java
Information about the Java programming language, the JVM itself, and about other programming languages that are implemented for the JVM.
General Stuff
The Java Language Specification
See here for the various versions of the JLS and also the Java Virtual Machine Specifications for the various editions, beginning with Java 6. Both documents are available as PDF, too. See here for “The Java Language Specification, Second Edition”, covering the language as it was before Java 5.
For the currently relevant versions, the respective links are in the sections for that version, below.
Important changes were made in Java 5 (Generics, enum, static imports …), Java 8 (Lambdas, …), and Java 9 (Modules, …),
JVM Languages
The Java Scripting API (JSR223)
AWT and Swing
- Using Headless Mode in the Java SE Platform
This article explains how to use the headless mode capabilities of the Java Platform, Standard Edition (Java SE, formerly referred to as J2SE). It is a little bit old, but still valid, as long as AWT (and Swing) are part of the Java Platform.
JavaFX does not provide a headless mode, but if java.awt.headless="true" is set, a JavaFX GUI will most probably not start, too.
Java 17
Java 21
Java 22
