In my previous blog post, I did some experimentation with simultaneous execution of multiple threads. Since the threads were all doing relatively large chunks of work, the overhead from thread creation and management was almost irrelevant. In this post, I take a look at the overhead that launching a series of threads can have on an application. The starting point is a modified version of the...
Multithreaded programming has been possible in Java for a very long time. That's a good thing, since modern computers and even many mobile phones are multicore today. If an application is primarily interactive, its processing speed is fairly irrelevant today -- the limiting time factor is how fast the user can type or move and click the mouse or touch the screen, etc. But, to increase the speed...
About a month ago, I tried to get started with the JavaFX 2.1 Developer Preview on my CentOS 5.5 Linux system. I didn't get very far, due to dependency problems (a great many of the CentOS 5.5 packages were too old). After deciding I didn't want to risk making my system unstable, I took a look at the package list for the latest CentOS (6.2) and found that the great majority its package versions...
Today I attended the Oracle Technology Network's Java Virtual Developer Day, a four-hour online event that takes a pretty deep dive into Java 7 and JavaFX 2.0. The agenda started with a keynote presentation, "The Java Platform: Now and the Future," followed by a general session, "What is Java SE 7 and JDK 7." These were presented by Simon Ritter, Technology Evangelist, Oracle. Following the...
Among the conferences I hope to attend some day is Jfokus, held annually in Stockholm, Sweden. In my view, Jfokus exemplifies an emerging trend where Java-centric conferences that originally started out as smaller, regional events ultimately attain international stature. It seems to me that conferences like Jfokus are increasingly taking on a greater role in helping developers network, exchange...
In the most recently completed Java.net poll, the Java/JVM developers who chose to participate generally anticipate stable or increased job opportunities in 2012. A total of 373 votes were cast, with the following results: In 2012, job opportunities for Java/JVM developers will... 19% (72 votes) - Expand rapidly 25% (92 votes) - Increase moderately 23% (86 votes) - Remain stable 9% (33 votes...
Last night I dreamed seemingly all night about NetBeans 7.1, the JavaFX 2.1 Developer Preview, the JDK 6 and JDK 7 installations on my CentOS Linux system, Java threads, the JDK 7 Fork/Join framework, closures... and probably a few more things were in there too. That kind of thing happens to me sometimes after a late night of programming or development-related brainstorming. Now, if these...
