Programming
Brian Goetz recently provided new details on the status of JSR 335 in his OpenJDK document "State of the Lambda: Libraries Edition." Project Lambda is a fundamentally important enhancement to Java 8. And, based on the response of developers in our recent poll...
A few nights ago, I was browsing the chapters about concurrent programming in Herbert Schildt's excellent "Java: The Complete Reference, 8th Edition," and I was struck by the evolution of concurrency in Java over the years, from threads, through the richness of Java 5's Concurrency Utilities, and on to Java 7's Fork/Join Framework...
With the advent of multicore processors on everything from desktop computers to tablets, pads, and even mobile phones, parallel processing is gaining increasing attention. This is at least in part what's behind the release of the Fork/Join Framework in Java 7, and the inclusion of Lambda Expressions...
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...

In some earlier posts, I've talked about Java threads, Java Thread Overhead, and Amdahl's Law and Parallel Processing Speed-Up. My next investigation in this series is Java 7's new Fork/Join Framework. I plan to spend quite a lot of time in this particular investigation...
JavaOne
"The multicore challenge" is the challenge to developers of software products to write code that effectively utilizes modern multi-core / multi-processor computers. Two years ago, I wondered if the multicore challenge was still relevant. In part, I was thinking about how applications were moving from the desktop into the cloud. So, if the apps people are running are running in a browser, does it matter if their desktop system (or pad or phone) is multicore?...

The Enterprise Architectures for Java EE Weighting Survey ends this Friday, June 25. Kate Jones of Oracle recently talked about the survey and its purpose...
