I recently returned from a long business trip, and while working through my email backlog I’ve come across several questions from developers who are working with the Open XML formats.  I’ve responded to each of them with some tips on how to best get such questions answered, and I  thought I’d summarize that information here for others who may find it useful. Your first stop for most Open XML development questions should be the forums section of the Open XML Developer web site.  You can post a question there and it will be seen by the people who manage that site, and also by the broader Open XML developer community.  Over 4,000 comments have been posted to those forums, so you can also learn quite a bit by reviewing the existing threads.  And the library section of the site has dozens of articles with Open XML code samples in many programming languages, including Java, C#, C++, PHP, Ruby, Python, and others.

Oracle’s Daniela Florescu gave a talk at UC Irvine this May entitled The Magic Is In The Glue: XQuery + Cloud. A coworker pointed me to the slides here , which I thought I’d share in a more convenient SlideShare-based format and agree with violently in more than a few respects. First, let’s excerpt the abstract to tee things up: Ten years have passed since the W3C initiated its effort to design a query language for what, in 1999, was a new and controversial semi-structured data format, namely XML

PHPPowerPoint 0.1.0 was released last week, as an open-source PHP API for generating PPTX files, much like the PHPExcel API for XLSX files.  Maarten Balliauw has a blog post with more information, download links, and sample code. A new post at OpenXMLDeveloper.org covers the Simple OOXML Library , a set of classes that sit on top of the Open XML SDK to help developers create word-processing documents and spreadsheets quickly with minimal programming required.  The abstractions of this library make it possible to be immediately productive with Open XML even if you haven’t studied the details of the spec yet

On the previous post in this blog using Indonesian language, we tried to use property file to access database in order to avoid hardcode mechanism, and the accessing of the property file by using a class named ConfigProperties, now we will try to access property file without using those class but we will try to use Spring Framework to access property file . As we knew, the existence of Spring Framework on Java technology is really-really help us the Java Developer, the modularity of this framework has made the enterprise java project development is easier to rebuild or modify. We will not discuss much more about the Spring Framework here, we only will try to use the Spring Framework one of this framework feature to access property file.

One day, there’s some one came to me and intent to start learning Java programming, she asked a lot about Java and it’s technology. One of her question based on her story-told is how can we make a Java application which is able to generate an array of prime number?, the problem is, I have forgotten what is the definition of prime number it self, so we had a problem to make the application that will appropriate with her idea. ha..ha..ha..(what an excuse…!!!).

In the first installment of this post, I discussed the move that all of the major computer hardware vendors have made toward multi-core CPUs, and the resulting Multi-core Dilemma .  I then summarized their strategies in two categories: homogenous and heterogenous. In Part 2, I’ll talk about pros and cons of each approach and some things to think about as you plan your parallel strategy

Homogenous vs. heterogenous multi-core: hardware strategies (Part 2)

Avik Sengupta from Lab49 wrote an interesting Guest View in the latest SDTimes about recent additions to Java to improve support for programming to multi-core hardware.  When I started talking about the Multi-core Dilemma a few years ago the conventional wisdom in the Java community still held that we wouldn’t have to do anything different  – that Java would take care of it for us.  I even touched off a nice little flame war with a posting on The Server Side… As Avik points out, Java does provide a powerful threading model that helps with multi-core, “ but in practice it may not be so easy. “  With the addition of the concurrency package and the new fork/join, the tools for parallelism in Java are greatly improved
