• Eclipse and NetBeans replacing embedded IDEs (part 2 and part 3)

  - by Geertjan

  After part 1, in Embedded Insights, the series Eclipse and NetBeans replacing embedded IDEs by principal analyst Robert Cravotta continues below. Many embedded tool developers are choosing to migrate their embedded development toolset to an open source IDE platform for a number of reasons. Maintaining an up-to-date IDE with the latest ideas, innovations, and features requires continuous effort from the tool development team. In contrast to maintaining a proprietary IDE, adopting an open source IDE platform enables the tool developers to leverage the ideas and effort of the community and take advantage of advances in IDE features much sooner and without incurring the full risk of experimenting with new features in their own toolsets. Both the Eclipse and NetBeans platforms deliver regular releases that enable tool developers to more easily take advantage of the newest features in the platform architecture.  Read more of part 2 here, in an article published Thursday, May 17th, 2012. Both the NetBeans and Eclipse projects began as development environments and both evolved into platforms that support a wider array of software products. Both platforms have been actively supported and evolving open source projects that have competed and coexisted together for the past decade and this has led to a level a parity between the two platforms. From the perspective of a tool developer, applications are built the same way on either platform – the difference is in the specific terminology and tools. Read more of part 3 here, in an article published Tuesday, June 12th, 2012. And, as a bonus in this blog entry, here's how to get started creating an IDE on the NetBeans Platform:  http://netbeans.dzone.com/how-to-create-commercial-quality-ide

• LIbgdx and android scaling

  - by petervaz

  Following my previous question, I decided to migrate my andengine game to libdgx to have the desktop option. The game assets were planned, at first, to use a 1080x600 resolution and I raised that to 1200x800 which is native for many tablets and would look better on monitors. I followed this blog aproach regarding aspect ratio, which worked nicely on the desktop version, but running the android version (on my smaller tablet), the background would still appear on the original size being cropped by the smaller screen size. How can I force the resize of the background (or for what matter, of everything) on android to fit the screen?

• two thoughts about career excellence

  - by john.rose

  I love Dickens, warts and all. Sometimes he is sententious, and (like the mediocre modern I am) at such points I am willing to listen non-ironically. This bit here struck me hard enough to stop and write it down: I mean a man whose hopes and aims may sometimes lie (as most men's sometimes do, I dare say) above the ordinary level, but to whom the ordinary level will be high enough after all if it should prove to be a way of usefulness and good service leading to no other. All generous spirits are ambitious, I suppose, but the ambition that calmly trusts itself to such a road, instead of spasmodically trying to fly over it, is of the kind I care for. It is Woodcourt's kind. (John Jarndyce to Esther Summerson, Bleak House, ch. 60) Woodcourt is, of course, one of the heroes of the story. It is a heroism that is attractive to me. Here is a similar idea, from the Screwtape Letters. In the satirically inverted logic of that book, the “Enemy” is God, the enemy of the devils but the author of good: The Enemy wants to bring the man to a state of mind in which he could design the best cathedral in the world, and know it to be the best, and rejoice in the, fact, without being any more (or less) or otherwise glad at having done it than he would be if it had been done by another. (C.S. Lewis, Screwtape Letters, ch. 14) Though I will be happy with a good Bazaar, I also dream of Cathedrals. Put whatever name you like on it, as long as I get some part in the fun of building a good one.

• How to trace a function array argument in DTrace

  - by uejio

  I still use dtrace just about every day in my job and found that I had to print an argument to a function which was an array of strings.  The array was variable length up to about 10 items.  I'm not sure if the is the right way to do it, but it seems to work and is not too painful if the array size is small.Here's an example.  Suppose in your application, you have the following function, where n is number of item in the array s.void arraytest(int n, char **s){    /* Loop thru s[0] to s[n-1] */}How do you use DTrace to print out the values of s[i] or of s[0] to s[n-1]?  DTrace does not have if-then blocks or for loops, so you can't do something like:    for i=0; i<arg0; i++        trace arg1[i]; It turns out that you can use probe ordering as a kind of iterator. Probes with the same name will fire in the order that they appear in the script, so I can save the value of "n" in the first probe and then use it as part of the predicate of the next probe to determine if the other probe should fire or not.  So the first probe for tracing the arraytest function is:pid$target::arraytest:entry{    self->n = arg0;}Then, if I want to print out the first few items of the array, I first check the value of n.  If it's greater than the index that I want to print out, then I can print that index.  For example, if I want to print out the 3rd element of the array, I would do something like:pid$target::arraytest:entry/self->n > 2/{    printf("%s",stringof(arg1 + 2 * sizeof(pointer)));}Actually, that doesn't quite work because arg1 is a pointer to an array of pointers and needs to be copied twice from the user process space to the kernel space (which is where dtrace is). Also, the sizeof(char *) is 8, but for some reason, I have to use 4 which is the sizeof(uint32_t). (I still don't know how that works.)  So, the script that prints the 3rd element of the array should look like:pid$target::arraytest:entry{    /* first, save the size of the array so that we don't get            invalid address errors when indexing arg1+n. */    self->n = arg0;}pid$target::arraytest:entry/self->n > 2/{    /* print the 3rd element (index = 2) of the second arg. */    i = 2;    size = 4;    self->a_t = copyin(arg1+size*i,size);    printf("%s: a[%d]=%s",probefunc,i,copyinstr(*(uint32_t *)self->a_t));}If your array is large, then it's quite painful since you have to write one probe for every array index.  For example, here's the full script for printing the first 5 elements of the array:#!/usr/sbin/dtrace -spid$target::arraytest:entry{        /* first, save the size of the array so that we don't get           invalid address errors when indexing arg1+n. */        self->n = arg0;}pid$target::arraytest:entry/self->n > 0/{        i = 0;        size = sizeof(uint32_t);        self->a_t = copyin(arg1+size*i,size);        printf("%s: a[%d]=%s",probefunc,i,copyinstr(*(uint32_t *)self->a_t));}pid$target::arraytest:entry/self->n > 1/{        i = 1;        size = sizeof(uint32_t);        self->a_t = copyin(arg1+size*i,size);        printf("%s: a[%d]=%s",probefunc,i,copyinstr(*(uint32_t *)self->a_t));}pid$target::arraytest:entry/self->n > 2/{        i = 2;        size = sizeof(uint32_t);        self->a_t = copyin(arg1+size*i,size);        printf("%s: a[%d]=%s",probefunc,i,copyinstr(*(uint32_t *)self->a_t));}pid$target::arraytest:entry/self->n > 3/{        i = 3;        size = sizeof(uint32_t);        self->a_t = copyin(arg1+size*i,size);        printf("%s: a[%d]=%s",probefunc,i,copyinstr(*(uint32_t *)self->a_t));}pid$target::arraytest:entry/self->n > 4/{        i = 4;        size = sizeof(uint32_t);        self->a_t = copyin(arg1+size*i,size);        printf("%s: a[%d]=%s",probefunc,i,copyinstr(*(uint32_t *)self->a_t));} If the array is large, then your script will also have to be very long to print out all values of the array.

• Java EE Basic Training with Yakov Fain

  - by reza_rahman

  Those of us that have been around Java/Java EE for a little while sometimes tend to forget that Java is still an ever expanding ecosystem with many newcomers. Fortunately, not everyone misses this perspective, including well-respected Java veteran Yakov Fain. Yakov recently started a free online video tutorial series focused on Java and Java EE for absolute beginners. The first few parts of the series focused on Java SE but now Yakov is beginning to cover the very basics of Java EE. In a recent video he covered: The basics of the JCP, JSRs and Java EE How to get started with GlassFish 4 The basics of Servlets Developing Java EE/Servlets using Eclipse and GlassFish The excellent video is posted below. The slides for the tutorial series generally are available here. If there are folks you know that would benefit from this content, please do pass on word. Even if you are an experienced developer, it sometimes helps to sit back and review the basics... It's quite remarkable that someone of Yakov's stature took the time out to create content for absolute beginners. For those unaware, Yakov is one of the earliest Java champions and one would be very hard pressed to match his many contributions to the Java community. The tutorial demonstrates his continued passion, commitment and humility.

• Meet the Spec Leads & Active JSRs

  - by heathervc

  For your Monday reading pleasure, the JCP has published Spec Lead Profiles of In Progress/Active JSRs--there are 35 of these Spec Leads!  Find out more about these dedicated community leaders.  In preparing these profiles, the PMO also asked Specification Leads to tell about their experiences  as Spec Leads.  There were many themes that emerged around transparency, openness, agility and participation.  This led to a related article for those interested in learning about the experience of participating in the development of a Java Specification through the JCP program, see: "Active Specification Leads Offer Best Practices and Tips for Success". In Progress/Active JSRs were also reported on in the PMO Presentation during the last JCP EC Face-to-Face meeting in September 2012.   Now is a good time to start thinking about nominations for Star Spec Leads.  Nominations for 2012 are now open.  Anyone can submit a nomination for Star Spec Lead; however, we ask that you nominate an active JSR Spec Lead, operating a JSR under JCP program version 2.8 (introduced October 2011) or above.  Nominations close 31 December 2012.

• Jersey 2.0 Milestone 2 Now Available

  - by arungupta

  Jersey 2.0 milestone 2 is now available. It builds upon the first milestone and adds several new features such as server-side asynchronous processing, server-side content negotiation, improved JAX-RS parameter injection, and several others. The REST endpoints can be published on Java SE HTTP Server, Grizzly 2 HTTP container, and some basic Servlet-based deployments. It also provides HTTPURLConnection-based client API implementation. Read about these and more about what's new in Marek's detailed post. Of course this is also the future reference implementation for JAX-RS 2.0. Feel like trying it out? Simply go to Maven Central (of course none of this is production quality at this point). The latest JAX-RS Javadocs and Jersey 2.0 API docs are good starting points to explore. And provide them feedback at [email protected].

• New "How do I ..." series

  - by Maria Colgan

  Over the last year or so the Optimizer development team has presented at a number of conferences and we got a lot of questions that start with "How do I ...". Where people were looking for a specific command or set of steps to fix a problem they had encountered. So we thought it would be a good idea to create a series of small posts that deal with these "How do I" question directly. We will use a simple example each time, that shows exactly what commands and procedures should be used to address a given problem. If you have an interesting "How do I .." question you would like to see us answer on the blog please email me and we will do our best to answer them! Watch out for the first post in this series which addresses the problem of "How do I deal with a third party application that has embedded hints that result in a sub-optimal execution plan in my environment?"

• Using the Coherence ConcurrentMap Interface (Locking API)

  - by jpurdy

  For many developers using Coherence, the first place they look for concurrency control is the com.tangosol.util.ConcurrentMap interface (part of the NamedCache interface). The ConcurrentMap interface includes methods for explicitly locking data. Despite the obvious appeal of a lock-based API, these methods should generally be avoided for a variety of reasons: They are very "chatty" in that they can't be bundled with other operations (such as get and put) and there are no collection-based versions of them. Locks do directly not impact mutating calls (including puts and entry processors), so all code must make explicit lock requests before modifying (or in some cases reading) cache entries. They require coordination of all code that may mutate the objects, including the need to lock at the same level of granularity (there is no built-in lock hierarchy and thus no concept of lock escalation). Even if all code is properly coordinated (or there's only one piece of code), failure during updates that may leave a collection of changes to a set of objects in a partially committed state. There is no concept of a read-only lock. In general, use of locking is highly discouraged for most applications. Instead, the use of entry processors provides a far more efficient approach, at the cost of some additional complexity.

• How can you identify duplicate CSS rules?

  - by DanMan

  I'm not talking about used/unused here. I have two stylesheets and some rules differ (either in selectors, rules or both) and some are exactly the same. So I'm looking for a way to extract and move those rules, which are the same in both files, into a third stylesheet. In other words: an intersection of two stylesheets. Strangely, I couldn't find a software for this. Would have expected this to be a more common problem. Background, for those who care: I'm converting a desktop website into a mobile one and I've started by duplicating the desktop stylesheet and changing it (throwing stuff out, adding to it).

• Free & Open Source XML Editor Built on Maven

  Here you can download the sources of an XML Editor that uses libraries from NetBeans IDE 7.3 Beta 2 as its basis, while using Maven as its build system: http://java.net/projects/nb-api-samples/sources/api-samples/show/versions/7.3/misc/XMLEditorInMavenNBRCP And here's what it looks like to the user: Note: The Favorites window has been rebranded as "File Browser" and Nimbus is used for the look and feel, thanks to a .conf file that is registered in the POM of the application project.  The cool part is that I didn't type one line of code to get the above result and that only those pieces that an XML Editor actually needs are included in the application, though it could be pruned even further.
