Beware of Java’s inconsistent MIN_VALUE

An astute user of my Tektosyne library noticed that I had made a simple but disastrous copy-paste mistake regarding the floating-point versions of some basic algorithms, such as finding the maximum of an array of numbers. The integral versions initialize the return value to e.g. Integer.MIN_VALUE and then check for any greater values. I copied … Continue reading “Beware of Java’s inconsistent MIN_VALUE”

Java 9 Incompatibilities

Last year I took a quick look at the newly released Java SE 9 but wanted to delay updating until the corresponding NetBeans version was out. Nothing happened, so that’s the first incompatibility to discuss, followed by JavaMail and JavaFX issues. NetBeans MIA(pache) After four months NetBeans is still in Apache incubator limbo with no … Continue reading “Java 9 Incompatibilities”

Java SE 9 First Look

Oracle has finally released Java SE 9, now available on the Oracle Technology Network. As usual the official end-user portal java.com will switch versions later, so for now it still distributes Java SE 8u144. I have yet to install the JDK, as the corresponding NetBeans update was delayed by its transition from Oracle to Apache. … Continue reading “Java SE 9 First Look”

Java Performance Notes

There have been several remarkable articles on Java performance issues in the last couple of months. Those links tend to get lost on Twitter, so I wanted to compile them here with brief overviews. All articles are based on the OpenJDK which also underlies Oracle’s distributions. Java and SIMD Piotr Nowojski tests automatic loop vectorization, … Continue reading “Java Performance Notes”

Myriarch for Java

Myriarch Combat Simulator is now available in an enhanced Java version, with a JavaFX user interface.

Overview Myriarch attempts a precise real-time simulation … Continue reading “Myriarch for Java”
