• The type of programmer I want to be [closed]

  - by Aventinus_

  I'm an undergraduate Software Engineer student, although I've decided that pure programming is what I want to do for the rest of my life. The thing is that programming is a vast field and although most of its aspects are extremely interesting, soon or later I'll have to choose one (?) to focus on. I have several ideas on small projects I'd like to develop this summer, having in mind that this will gain me some experience and, in the best scenario, some cash. But the most important reason I'd like to develop something close to “professional” is to give myself direction on what I want to do as a programmer. One path is that of the Web Programmer. I enjoy PHP and MySQL, as well as HTML and CSS, although I don't really like ASP.NET. I can see myself writing web apps, using the above technologies, as well as XML and Javascript. I also have a neat idea on a Facebook app. The other path is that of the Desktop Programmer. This is a little more complicated cause I really-really enjoy high level languages such as Java and Python but not the low level ones, such as C. I use both Linux and Windows for the last 6 years and I like their latest DEs (meaning Gnome Shell and Metro). I can see myself writing desktop applications for both OSs as long as it means high level programming. Ideally I'd like being able to help the development of GNOME. The last path that interests me is the path of the Smartphone Programmer. I have created some sample applications on Android and due to Java I found it a quite interesting experience. I can also see myself as an independent smartphone developer. These 3 paths seem equally interesting at the moment due to the shallowness of my experience, I guess. I know that I should spend time with all of them and then choose the right one for me but I'd like to know what are the pros and cons in terms of learning curve, fun, job finding and of course financial rewards with each of these paths. I have fair or basic understanding of the languages/technologies I described earlier and this question will help me choose where to focus, at least for now.

• Overview of XSLT

  - by kaleidoscope

  XSLT (Extensible Stylesheet Language Transformations) is a declarative- XMLbased language used for the transformation of XML documents into other XML documents. Using XSLT , the original document does not changed; rather, a new document is created based on the content of an existing one. XSLT is developed by the World Wide Web Consortium (W3C).   Using XSLT we can transform source xml file into another xml file, word file or Excel file.    XSLT Functions : -   There are the following built - in XSLT functions :   Name Description current() Returns the current node document() Used to access the nodes in an external XML document element-available() Tests whether the element specified is supported by the XSLT processor format-number() Converts a number into a string function-available() Tests whether the function specified is supported by the XSLT processor generate-id() Returns a string value that uniquely identifies a specified node key() Returns a node-set using the index specified by an <xsl:key> element system-property() Returns the value of the system properties unparsed-entity-uri() Returns the URI of an unparsed entity   For more information –   http://www.w3schools.com/xsl/default.asp   Technorati Tags: Ritesh, Overview of XSLT

• Are there any reasons to use Bazaar over Hg or Git?

  - by NeuronQ

  The world of DVCSs seems split between Git and Mercurial nowadays, but lots of projects and places (like my new employer) use Bazaar. And it's not a thing of inertia where people just use something because "that's how it's always been done", these guys are agile and sometimes seem to embrace change just for the fun of having more things to fix. Yet no one gave me any convincing arguments for using Bzr over Hg or Git. I can get seeing Git as "too complicated" but you can't use this king of judgement between Hg and Bzr. So then, what are the features of Bazaar that would justify its use over Mercurial (or Git) in any given situation?

• At what point does a good programmer know he is skilled programmer? [closed]

  - by Eritrea

  Possible Duplicate: How Can I Know Whether I Am a Good Programmer? I am just guessing, there is no end to programming, there is always someone who know what you do not know, once you learn it all something evolves out of somewhere, and you have to learn that one. It is a perpetually process eventually. But, at what point can you consider yourself, you are worth much in the programming world? By the amount of your reputation on Stackechange or if you create your own software...? When can you even know?

• Building an instance system.

  - by Kyle C

  I am looking into how to design an instance system for the game I am working on. I have always wondered how these are created in games like World of Warcraft, where instances == dungeons/raids/etc). Areas that are separated from players other than those in your group, but have specific logic to them. Specifically how can you reuse your existing code base and not have a bunch of checks everywhere ? if (isInstance) do x; else do y; I don't know if this will make too much of a difference on any answers, but we're using a pretty classic "Object as pure aggregation" component system for our entities.

• Why does Bing not show my adcenter ads though there is enough space

  - by gamma

  I created several campaigns using the MS adcenter. I'm targeting the whole world at any time with 2-3 placement texts per keyword group. The bids I placed are sometimes quite high, so they should get displayed. When I try to search for my keywords in Bing nothing gets displayed, though there is plenty of space for it. Bing mostly displays 2-3 ads, but the ones at the right side rather seldom. I'd like to know, how I can improve the fact that my ads are not being displayed - without increasing the bids any further.

• Proxy Client for Ubuntu

  - by WindowsEscapist

  I want to use a proxy for web browsing similar to Ultrasurf for Windows. I've tried to use TOR, but it isn't working! The problem is whenever I search something along the lines of "ubuntu + linux proxy", sites assume that I want to set up a proxy server rather than use one. I just want something with little to no configuration needed (i.e. I don't have my own proxy server). UltraSurf is a free software which enables users inside countries with heavy Internet censorship to visit any public web sites in the world safely and freely. Users in countries without internet censorship also use it to protect their internet privacy and security.

• What parts of Java I should know by now?

  - by WinstonChurchill

  I have been working in the enterprise Java field, mostly for financial institutions, for about seven years. Beyond core Java, what are "parts" of Java I should know by now? Should as in it will be useful either to nail the interview, or in an actual job. For example, I have never used JSP beyond "hello, world", but I don't suppose that it's something I need to go learn. But I have got core Spring pretty well done. I've read up on GC but that was a while back and need to re-visit it. I'm looking for one suggestion per post please.

• 12.04 - sound is laggy when running games through Wine

  - by orzechowskid

  Lenovo U400 Wine 1.5.5 Ubuntu 12.04 with all updates applied I'm experiencing severe (~500ms) audio lag in all games run in Wine. Portal 2, Half-Life, World of Goo, and Fallout are all exhibiting this problem. When I run winecfg though and click the "Test Sound" button at the bottom of the Audio tab, the sound effect appears to play immediately. So I'm not sure what's going on. I don't think it's a problem with PulseAudio by itself since totem videos and Youtube clips both play in perfect sync. Anyone have any ideas on where to start fixing this? thanks! (edit: I thought this was limited to Steam games but I installed a non-Steam game and I now see that's not the case. I get audio lag in other apps too.)

• how to avoid workaholic tag

  - by Shirish11

  As we all know a programmer just needs a computer and a network connection. When these things are available at your disposal you can program anywhere in the world. Now this is causing me a bit of problems. Since its not necessary to work at your workplace only you are asked anytime of your vacation or week-off to help out the client on reported bug. Also if you do enjoy doing it at your pass time, any one seeing you stare at the computer may treat you workaholic which I don't enjoy. How do you make them realize that its not just about the work.It can be a hobby also. In my understanding a workaholic is a person who works to earn but an enthusiast is the one who works to learn.

• OpenGLES 2.0 gluunProject

  - by secheung

  I've spent more time than i should trying to get my ray picking program working. I'm pretty convinced my math is solid with respect to line plane intersection, but I believe the problem lies with the changing of the mouse screen touch into 3D world space. Heres my code public void passTouchEvents(MotionEvent e){ int[] viewport = {0,0,viewportWidth,viewportHeight}; float x = e.getX(), y = viewportHeight - e.getY(); float[] pos1 = new float[4]; float[] pos2 = new float[4]; GLU.gluUnProject( x, y, 0.0f, mViewMatrix, 0, mProjectionMatrix, 0, viewport, 0, pos1, 0); GLU.gluUnProject( x, y, 1.0f, mViewMatrix, 0, mProjectionMatrix, 0, viewport, 0, pos2, 0); } Just as a reference I've tried transforming the coordinates 0,0,0 and got an offset. It would be appreciated if you would answer using opengl es 2.0 code. Thanks

• What is the best way to learn C# programming? [closed]

  - by MSU

  My case I want to get the capability of doing anything in C# from building applications to solving problems. I searched for and tried to read books. Then one of the experts said that reading books will not make any good and that to learn, you have to solve real world problems in C#, and he gave me some problems which I previously solved in C++. The thing is that while I know the internal logic of solving the problem, I don't know how to implement it using C# efficiently. I know the message to pass but not the exact way to pass it. I did a program to solve a problem, then find out there are much easier ways of doing it wherever I was doing it in tougher way. What I need to get hold of the language and get the ability to code in C# proficiently?

• Technical Article: Experimenting with Java Timers

  - by Tori Wieldt

  OTN's new tech article is "Experimenting with Java Timers" by T. Lamine Ba. This article studies time—how Java handles timers and the scheduling of tasks. Java timers are utilities that let you execute threads or tasks at a predetermined future time, and these tasks can be repeated according to a set frequency. The article starts with a simple "Hello World" program in a web application that's composed of JavaServer Pages (JSP) and uses the model-control-view (MVC) design pattern. The IDE used in this article is NetBeans IDE 7.1, but you can use any IDE that supports Java. "Experimenting with Java Timers" demonstrates how to get started scheduling jobs with Java. To learn about Swing timers, check out the Java tutorial "How to Use Swing Timers" and additional information in the Java Platform, Standard Edition 7 API Specification for Class Timer.

• Progressing past CRUD applications in PHP?

  - by Anonymous -

  I've been programming in PHP for about a year and am at the following stage: Have a good 'feel' for the language Can create CRUD applications competently Can utilize an MVC structure to allow for future expansion of code Using the points listed above, I've created a number of my own applications for practise - including but not limited to; a forum, social network etc. My question may be a little vague but should hopefully be answerable. I feel as though there isn't anything else I would need to know about PHP to allow me to create websites, though I'm sure I'm wrong. What advanced/complex PHP topics could I look at that have a real-world use and will allow me to enhance both my skill as a programmer and applications in general? Recently I've looked a lot more at javascript/jQuery allowing me to give my applications a richer user interface which has been a great learning experience and proving very useful.

• Communication between Box2D and libGDX Stage (Scene2D) running in separate threads

  - by atok

  I'm making a physics based 2D game using libGDX and Box2D. I want to move the execution of the simulation out of render thread. I use immutable messages and the BlockingQueue to pass the information about player actions. The Box2D applies forces and runs a frame of simulation. In the next step I would like to sync back the changes and update Scene2D Actors accordingly. Making an immutable copy of the state of the game world and sending it back using Gdx.app.postRunnable() is one option but it seems inefficient. Is there any other option?

• Collision Detection within Player/Enemy Class

  - by user1264811

  I'm making a 2D platform game. Right now I'm just working on making a very generic Player class. I'm wondering if it would be more efficient/better practice to have an ActionListener within the Player class to detect collisions with Enemy objects (also have an ActionListener) or to handle all the collisions in the main world. Furthermore, I'm thinking ahead about how I will handle collisions with the platforms themselves. I've looked into the double boolean arrays to see which tiles players can go to and which they can't. I don't understand how to use this class and the player class at the same time. Thank you.
