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”

Programming Languages in 2016

According to two out of three major language surveys I consulted for 2016, programming is increasingly becoming synonymous with web development in JavaScript. No doubt this reflects, on the developer side, the rapid march towards web services and HTML applications everywhere in computing. Other than JavaScript and HTML itself, though, a stable comprehensive application framework … Continue reading “Programming Languages in 2016”

Algorithms in a Nutshell

Algorithms in a Nutshell — George T. Heineman, Gary Pollice & Stanley Selkow, O’Reilly 2016 (2nd ed.), ISBN 978-1-491-94892-7 This fairly slim book covers the basics of algorithmics and benchmarking, and also provides pseudocode and implementations (in C/C++, Java, and Python) for nearly 40 important algorithms.

CSS: The Missing Manual

CSS: The Missing Manual — David Sawyer McFarland, O’Reilly 2015 (4th ed.), ISBN 978-1-491-91805-0 McFarland’s eminently practical book explains the structure and features of CSS from the perspective of a raw beginner. This does lead to some amusing baby steps, such as the introductory section on “mouse clicks,” but don’t let that deter you. McFarland … Continue reading “CSS: The Missing Manual”

Programming Languages in 2015

You probably already heard that Java topped the TIOBE index in 2015, with an impressive growth spurt of 6% that put it close to 2006 levels and clearly outdistanced stagnant C (21.5% vs 16%). The rest of the field remained fairly unchanged, except for rapidly declining Objective-C, suggesting that Java drew renewed interest from across … Continue reading “Programming Languages in 2015”

JavaFX DPI Scaling: Fixed!

The upcoming Java release 8u60 is set to finally fix the JavaFX DPI scaling issues on Windows that I described back in August 2013. To recap, JavaFX would scale the default application font to the current Windows DPI setting and the built-in controls would generally scale themselves around that font size. However, explicitly specified pixel … Continue reading “JavaFX DPI Scaling: Fixed!”

Programming Languages in 2014

With some delay, here’s my annual roundup of programming language rankings. One sad change from previous years (2012 edition, 2013 edition) is the absence of Andrew Binstock’s usual column, “Rise and Fall of Languages.” That had been published by Dr. Dobb’s Journal which has shut down last year. (Binstock is now EIC of Oracle’s Java … Continue reading “Programming Languages in 2014”

Java SE 8 Update 40 Released

Java Standard Edition 8 Update 40 is now upon us, and despite the “Update” designation this was a fairly massive feature release. You can find overviews at Java Source and Java Tutorials, and of course the detailed release notes. The changes I’m most interested in concern JavaFX, including accessibility support, new controls – more on … Continue reading “Java SE 8 Update 40 Released”
