  • AJAX or full page reload

    - by wh0
    I have a simple web page with top navigation and the content, on click of a certain link in top navigation content changes accordingly. Now my question is should do it using AJAX call and load the HTML it into content or should i reload the entire page.It is small page fetching data does not take much of the time but i wonder approach is better suited and why ? My opinion is AJAX way, but some of the web pages that i have seen goes for full page reload i wonder why. i'm not sure AJAX method it has any cons in it. Can someone please elaborate this for me.

  • Racing MMO for Linux - 2D or 3D - Massively Multiplayer Online Racing Games for Linux

    - by Paulocoghi
    I really like multiplayer racing games, like Need for Speed World or similar. I wonder if there is any MMO racing game for Linux (2D or 3D). Browser-based games are also accepted. Note: I tried this question in the Gaming Q&A of StackExchange (see link below), but one user said that my question was off-topic. http://gaming.stackexchange.com/questions/16329/racing-mmo-for-linux-2d-or-3d-massively-multiplayer-online-racing-games

  • What is the difference between nvidia-graphics-drivers and nvidia-graphics-drivers-updates

    - by Jarl
    I see that there are two packages nvidia-current and nvidia-current-updates. The apparently stem from nvidia-graphics-drivers and nvidia-graphics-drivers-updates respectively: https://launchpad.net/ubuntu/+source/nvidia-graphics-drivers https://launchpad.net/ubuntu/+source/nvidia-graphics-drivers-updates I wonder why there are two packages, and what is the difference between these two packages?

  • Sharing data between graphics and physics engine in the game?

    - by PolGraphic
    I'm writing the game engine that consists of few modules. Two of them are the graphics engine and the physics engine. I wonder if it's a good solution to share data between them? Two ways (sharing or not) looks like that: Without sharing data GraphicsModel{ //some common for graphics and physics data like position //some only graphic data //like textures and detailed model's verticles that physics doesn't need }; PhysicsModel{ //some common for graphics and physics data like position //some only physics data //usually my physics data contains A LOT more informations than graphics data } engine3D->createModel3D(...); physicsEngine->createModel3D(...); //connect graphics and physics data //e.g. update graphics model's position when physics model's position will change I see two main problems: A lot of redundant data (like two positions for both physics and graphics data) Problem with updating data (I have to manually update graphics data when physics data changes) With sharing data Model{ //some common for graphics and physics data like position }; GraphicModel : public Model{ //some only graphics data //like textures and detailed model's verticles that physics doesn't need }; PhysicsModel : public Model{ //some only physics data //usually my physics data contains A LOT more informations than graphics data } model = engine3D->createModel3D(...); physicsEngine->assingModel3D(&model); //will cast to //PhysicsModel for it's purposes?? //when physics changes anything (like position) in model //(which it treats like PhysicsModel), the position for graphics data //will change as well (because it's the same model) Problems here: physicsEngine cannot create new objects, just "assing" existing ones from engine3D (somehow it looks more anti-independent for me) Casting data in assingModel3D function physicsEngine and graphicsEngine must be careful - they cannot delete data when they don't need them (because second one may need it). But it's rare situation. Moreover, they can just delete the pointer, not the object. Or we can assume that graphicsEngine will delete objects, physicsEngine just pointers to them. Which way is better? Which will produce more problems in the future? I like the second solution more, but I wonder why most graphics and physics engines prefer the first one (maybe because they normally make only graphics or only physics engine and somebody else connect them in the game?). Have they any more hidden pros & contras?

  • The new Internet Explorer 7 Tax

    - by TATWORTH
    An Australian online retailer, Kogan, has just announced a 6.8% tax (really a surcharge) on users of IE7. (I wonder how IE6 users would be treated?)To avoid the surcharge, all users have to do is switch to more up to date IE or switch to an alternative browser such as Chrome, Firefox, Opera or Safari.One has to admire the pluck of such a retailer. More details at http://www.kogan.com/au/blog/new-internet-explorer-7-tax/

  • Secure an Application/Software by expiration with Date?

    - by JNL
    I have been working on some software application and I update them every 6 months. Currently, the way I track the date is by extracting the date from the system when the user installes the application, encrypt it and store it in a file locally. Whenever the application is started, it checks if 6 months have passed, then it works or it doesn't, in which case it shows an error message telling the user to update. I wonder whether there is a better way to do this. Any comments or suggestions would be highly appreciated

  • What strategies you followed to keep your programming skills fresh during a long break?

    - by TRoh
    After being away from development for more than a year, I find it challenging to join back the work force, and I can feel the rustiness. I wonder what you have done to either keep your skills fresh during such periods or how you gained back the skills you might have forgotten? I understand coding is a great way to become more competent, but how do you start getting more involved in it while you are not working as a developer?

  • Mathematics for Computer Science

    - by jiewmeng
    I am going into university next year. I think maths would be one of the more important aspects of computer science? I recently saw the MIT Intro to Algorithms video on YouTube and the maths required is quite hardcore. I wonder what parts of maths do i need, probability, calculus, trigo etc. Will the book Concrete Mathematics - it claims to be foundation for computer science - on Amazon cover most of whats required?

  • The Complexities to Creating Real Electronic Health Records

    <b>Linux Journal:</b> "But with all of this focus on streamlining and digitally electrifying health records, I began to wonder where did the Open Source community stand and where is its input?

  • How might one teach OO without referencing physical real-world objects?

    - by hal10001
    I remember reading somewhere that the original concepts behind OO were to find a better architecture for handling the messaging of data between multiple systems in a way that protected the state of that data. Now that is probably a poor paraphrase, but it made me wonder if there is a way of teaching OO without the (Bike, Car, Person, etc.) object analogies, and that instead focuses on the messaging aspects. If you have articles, links, books, etc., that would be helpful.

  • Google Earth freezes during zoom-in on Intel processors with integrated graphics

    When I zoom in at a certain zoom level, Google Earth makes my system freeze completely so that I have to power off or reboot I use Kubuntu 12.04 and my laptop has an Intel(R)Core(TM)i3-2310M CPU @2.10GHz with HD3000 graphics.

  • Converting #MDX to #DAX and PowerPivot Workshop online #ppws

    - by Marco Russo (SQLBI)
    I just published the article Converting MDX to DAX – First Steps on the renewed SQLBI web site about converting MDX to DAX. The reason is that with BISM Tabular in Analysis Services 2012 you will be able to write queries in both DAX and MDX. If you already know MDX, you might wonder how to “translate” your MDX knowledge in DAX. I think that this is another way you can improve your knowledge about DAX: it has different concepts behind and this comparison should be helpful in this purpose. This is...(read more)

  • Emacs column editing CUA mode - is it possible to select rectangular region with mouse?

    - by MountainX
    Rectangular or column editing is possible in emacs. And it is very easy with cua-mode enabled. Here are my references for this: Here's a video that shows how to do it: http://vimeo.com/1168225 And see section "CUA rectangle support" here: http://www.cua.dk/cua.html But I also wonder if I can do it with the mouse. I want to select the rectangular region entirely with the mouse (like Scite or Geany can do). Is that possible in emacs?
