• Automatic language transformation in editor or IDE [on hold]

  - by Rumca

  Are there any tools that are capable of editing code but in different language? To be more concrete, I want to parse java source file in editor, compile it to my language X, edit in X and compile back to java on save. Or edit pom.xml file using non-XML syntax. Which editor or IDE would be easiest to use for implementing such prototype? Option to transform only a snippet would be ideal to limit effort on parsing. For one example, Intellij IDEA can display anonymous class so it looks like lambda expression hiding some of boilerplate.

• Time it would take me to learn c++ given my speed? [closed]

  - by ashwin

  I am a student in second year of engineering and my life is hard, nowadays. To make my future secure and at least get good jobs, I have started learning C++; I have learned J2SE, ASP.NET (little, basic C#), PHP (little), HTML, CSS, AJAX, Javascript, SQL, a little android development (I have built a benchmark app) in 4 months and have received 1 gold medal in CSS and 1 each in HTML, CSS, Java. I am able to make things in C#, Java and all other, so I can apply all this knowledge. I was able to do all this, because I loved learning and I hate to ask this question. How much time would it take me to learn C++, good-enough to get good jobs at Google, Microsoft? I am currently learning data structures, so that's excluded.

  I am 23 and working as a Software Developer. Though my work is entirely based on Java and Advanced Java, I know a very little and all my interest is in developing games. I want to make a my career in Gaming Industry as a Game Programmer. I am not able to figure out the starting step to start with Game Programming. I have zero knowledge with developing games and never ever tried a tiniest of game. Please suggest me from where to start. Which programming language to start with? What should be my practice? What references to use? What type of games to begin with? BTW my preferable language would be C++ ~Thanks

• Multi-threaded JOGL Problem

  - by moeabdol

  I'm writing a simple OpenGL application in Java that implements the Monte Carlo method for estimating the value of PI. The method is pretty easy. Simply, you draw a circle inside a unit square and then plot random points over the scene. Now, for each point that is inside the circle you increment the counter for in points. After determining for all the random points wither they are inside the circle or not you divide the number of in points over the total number of points you have plotted all multiplied by 4 to get an estimation of PI. It goes something like this PI = (inPoints / totalPoints) * 4. This is because mathematically the ratio of a circle's area to a square's area is PI/4, so when we multiply it by 4 we get PI. My problem doesn't lie in the algorithm itself; however, I'm having problems trying to plot the points as they are being generated instead of just plotting everything at once when the program finishes executing. I want to give the application a sense of real-time display where the user would see the points as they are being plotted. I'm a beginner at OpenGL and I'm pretty sure there is a multi-threading feature built into it. Non the less, I tried to manually create my own thread. Each worker thread plots one point at a time. Following is the psudo-code: /* this part of the code exists in display() method in MyCanvas.java which extends GLCanvas and implements GLEventListener */ // main loop for(int i = 0; i < number_of_points; i++){ RandomGenerator random = new RandomGenerator(); float x = random.nextFloat(); float y = random.nextFloat(); Thread pointThread = new Thread(new PointThread(x, y)); } gl.glFlush(); /* this part of the code exists in run() method in PointThread.java which implements Runnable */ void run(){ try{ gl.glPushMatrix(); gl.glBegin(GL2.GL_POINTS); if(pointIsIn) gl.glColor3f(1.0f, 0.0f, 0.0f); // red point else gl.glColor3f(0.0f, 0.0f, 1.0f); // blue point gl.glVertex3f(x, y, 0.0f); // coordinates gl.glEnd(); gl.glPopMatrix(); }catch(Exception e){ } } I'm not sure if my approach to solving this issue is correct. I hope you guys can help me out. Thanks.

• Useful programming languages for hardware programming

  - by Sebastian Griotberg

  I am thinking to take the next semester a course called "Digital systems architecture", and I know that we need to program micro-controllers with several programming languages such as C, C++, verilog, and VHDL. I want to be prepared to take that course, but I need to know if I need to study deeper these languages. At this moment, I have taken one course in basic Java dealing with basic methods, data types, loop structures, vectors, matrices, and GUI programing. Must I study deeper Java and then go with C, and C++? Besides, I know basic verilog and VHDL.

• Empty Synchronized method in game loop

  - by Shijima

  I am studying the gameloop used in Replica Island to understand a bit about Android game development. The main loop has the below logic... GameThread.java (note the variable names in sample code dont match exact source code) while (!finished) { if (objectManager != null) { renderer.waitDrawingComplete(); //Do more gameloop stuff after drawing is complete... } } I was curious to see what waitDrawingComplete actually does, but found its just an empty syncrhonized method! I guess it does nothing, am I missing something here? GameRenderer.java line 328 public synchronized void waitDrawingComplete() { } Source code can be checked out here with SVN if you feel like having a look: https://code.google.com/p/replicaisland/source/checkout

• Use Android NDK for portability with iOS?

  - by J-F L-R

  I am currently planning to implement a little painting app using OpenGL ES 1.1. I believe this question applies to any OpenGL ES project. I am starting development on Android and I would like to know if you would recommend writing the drawing logic (using OpenGL) in C++ with the NDK so it will easier to port to iOS, or to use the Java API and being locked on Android. The reason I am asking that is because I have seen mixed opinions on the Web about using the NDK (some people say it is an added level of complexity). From what I have already seen, I believe that I should go with the Java API since I am starting on Android and then, if I decide to go on iOS, to rewrite the OpenGL logic in Objective-C or C++. This should be pretty straightforward since the calls appear to be the same in both languages. What do you think? Am I right?

• 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 users@jersey.java.net.

• Reduced Tree View in NetBeans IDE 7.2

  - by Geertjan

  Right-click within the Projects window in NetBeans IDE 7.2 and from the "View Java Packages As" menu, you can now choose "Reduced Tree".I never really understood the difference between "Reduced Tree" and the already existing "Tree". But it makes sense when you see it. Here's Reduced Tree view: And here's Tree view, where you can see that the "actions" and "nodes" packages above each have their own top level package nodes, which takes up more space than the above: What's cool is that your selected package view is persisted across restarts of the IDE. To be complete, here's the List view, which is the third option you have in the "View Java Packages As" menu: Seems to me like the new Reduced Tree view combines the best of the Tree view with the best of the List view!

• Is it normal to feel bad when someone insults a programming language? [closed]

  - by iammilind

  Few examples before the question: "A language is just a tool; Better to worry only about the concept." "C++ is just an object oriented language." "Java is more about the libraries and less about programming." "C# is just a Microsoft's version of Java with some extra things from C++." "Python is a scripting language used mainly for testing purpose." ... All these statements are made knowingly or unknowingly from my colleagues/friends and I often get to hear them. I feel bad when someone brings down any programming language. I don't know how to respond. Is there any one liner to enlighten those people?

• Creating a Lazy Sequence of Directory Descendants in C#

  My dear friend Craig Andera posted an implementation of a function that descends into a directory in a "lazy" manner, i.e. you get the first descendant back right away and not after all descendants have been calculated. His implementation was in Clojure, a Lisp variant that runs on the Java VM: (import [java.io File])(defn dir-descendants [dir]  (let [children (.listFiles (File. dir))]    (lazy-cat      (map (memfn getPath) (filter (memfn isFile) children))...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

• *raine Trip Report (Lorraine & Ukraine)

  - by delabassee

  Last week, I had the opportunity to talk about Java EE 7 in Nancy (Lorrraine - France) and Kiev (Ukraine). The first event was arranged by the local Lorraine JUG while the second one was a largest conference organised by the Ukraine Java User Group. Based on the overall feedback and discussions I had during those two events, it is clear that the WebSocket API (JSR 356) is really a hot topic. And travel issues aside, I have really enjoyed my time during those two events. Thanks to both JUGs for having me! A more detailed report can be found on my personal blog.

• Certifications needed to get an interview with no experience and no degree. [closed]

  - by Joel Cornett

  Possible Duplicate: Are certifications worth it? Given that I have no commercial experience to speak of -- and no undergraduate degree -- how can I best demonstrate my programming ability in order to interview for a job? How valuable are the various software certifications? Should I get the OCA? Should I submit samples of my code? Are there some other skills that I should develop? (I picked up Python and Java fairly quickly--a matter of weeks, actually.) I am a undergrad working on a triple major in math, stat and econ. I consider myself proficient with Python and have a working knowledge of Java.

• Is it smart to take a year off from school to get experience?

  - by user134147

  firstly I apologize if this question is not appropriate for the site, but I've seen other similar (though slightly deviant) questions on this sight before and I know the people here are the most qualified to answer my question. Anyways, I'm currently between my sophomore and junior years at a 4 year university, and after a bit of deliberation I've decided on computer science as a major (BA, by the way, as a BS would require me to stay at least an extra year the way our program is set up). I've been interested now in programming for a few months and I've developed a passion for it in a very short time. I began learning C++, migrating to Java recently when I learned my school focuses on this language. Now, I should mention that the concept of higher education has never sat well with me, so part of my motivation for wanting to take time off is to truly challenge myself and see what I can accomplish when I actually try at something. The autodidact in me finds it difficult to focus on my passions while trying to keep a high GPA in unrelated classes. However, I understand the times we live in and therefore would plan to complete my degree after this year. So my question is whether or not the skills I learn in a year off from college could justify the time off from school. Unfortunately, I don't believe I know enough yet to gain any professional experience (internship, etc.) so I would mostly focus my time on learning Java and another language, possibly Wordpress (to gain an understanding of web programming concepts as I have not yet decided what field I want to get into, and to make some money to fund my off-year), and to delve into security concepts, which also interest me. I'm hoping I could work on projects, such as simple applications or contributions to open source software during this time to enhance my resume once I do finish school, so I can find a job out of college easier. I do not want to be the new hire who knows nothing beyond the concepts of his Java textbooks. Does anyone have any input about these thoughts of mine, or any ideas for where I should focus my studies or how high I might set the bar for my work? Thanks a lot everyone!

• How do you learn to effectively use more than one framework

  - by LongTTH

  Someday, my leader told me that don't reinvent the wheels, use framework built-in classes. (with a serious mood) when I implement some algorithm has been supported by .NET fx. And seriously, I didn't know about these support before, cause this is the first time I work with .NET). So I have this questions. For example, for building an Web-App we have some ways: C# with ASP.NET framework Java with JavaEE (and friends like Struts, Spring v.v.) framework. PHP with Zend framework. ... It just takes about 1 months to learn language (C#, Java, PHP...), BUT learning to use a framework effectively takes you at least SOME YEARS working (to know every bit of code has been built-in). So, how do you learn to use effectively 2 (or more) frameworks? Any ideas are welcome!

• Qt Quick : des interfaces déclaratives hors normes ? Pourquoi ne sont-elles pas encore répandues ?

  Il y a peu, Nokia lançait Qt Quick, un nouveau module de Qt permettant de décrire des interfaces graphiques, un paradigme alors présenté comme assez nouveau. Or, une simple recherche à l'aide de Google montre bien que ces technologies ne sont pas récentes du tout, on trouve par exemple des traces de K, un langage presque ésotérique tellement il est peu connu du grand nombre actuellement, dans les années 90. Qu'est-ce qui a changé depuis lors ? Aussi, on peut remarquer que d'autres technologies phares dans le développement applicatif telles que .NET ou Java en disposent depuis belle lurette. On peut notamment citer XAML (arrivé avec le .NET Framework 3.0) du côté .NET ou Swul pour Java. Qu'ont-ils donc de différent ? Peut-on les comparer ? Ils tentent tous d'atteindre un cer...
