  • Cocos2D 2.0 - masking a sprite

    - by Desperate Developer
    I have read this tutorial about how to mask sprites using Cocos2D 2.0. http://www.raywenderlich.com/4428/how-to-mask-a-sprite-with-cocos2d-2-0 But the author talks about OpenGL ES textures and vertices as they were common knowledge. My knowledge about OpenGl is zero raised to infinity. All I want is to use a rectangle to mask a sprite to it. How I would do in Photoshop using a rectangle as mask (yes, I want to clip a sprite to the rectangle bounds and no, I do not want to use the ClippingNode solution, that do not works for animation/scaling etc.). So, can you guys translate the klingon language used in this tutorial and tell how a solid rectangle can be used to mask a sprite in Cocos2D? I am desperate, as my username states. I am searching this for a week and have tried several solutions without satisfactory results. Please help me. Thanks!

  • Advice for Storing and Displaying Dates and Times Across Different Time Zones

    A common question I receive from clients, colleagues, and 4Guys readers is for recommendations on how best to store and display dates and times in a data-driven web application. One of the challenges in storing and displaying dates in a web application is that it is quite likely that the visitors arriving at your site are not in the same time zone as your web server; moreover, it's very likely that your site attracts visitors from many different time zones from around the world.Consider an online messageboard site, like <a href="http://www.aspmessageboard.com/">ASPMessageboard.com</a>, where each of 1,000,000+ posts includes the date and time it was made. Imagine a user from New York leaves a post on April 7th at 4:30 PM and that the web server hosting the site

  • Why isn't Java more widely used for game development?

    - by Anto
    I'm not a game developer or anything, but I know that Java is not very widely used for game development. Java should be fast enough for most games, so where's the catch? I can think of some reasons: Lack of game developers with expertice in Java Lack of good game development frameworks Programmers don't want to accept Java as a games programming language. Most only accept C++ as that? No support for game consoles (though the PC market still exists) It could of course be something else. Could someone who knows the business better than me explain why Java isn't getting momentum when it comes to game development?

  • Creating natural environments that can run on lower end computers in Unity3D/C#

    - by Timothy Williams
    So, I'm starting work on a project soon that will require me to create realistic environments that can preferably run on PC's besides high quality ones. The goal is to get as real an environment as possible while still being easy(ish) to run. The only problem is I've NEVER done anything with 3D environments, making trees sway, grass move, lighting, etc. Can anyone give me any help? Perhaps describe how it's done? Link me to articles? I'm just looking to be pointed in the right direction, not for you to write the code for me. Any help at all would be greatly appreciated, I'm using Unity3D and C# as my language. Thanks, Tim.

  • Developing for Chrome App/Android?

    - by Johnny Quest
    I have been developing for win7 mobile (XNA/silverlight and will continue to do so, love everything about it) but I wanted to branch a few of my more polished games to google app store online, and perhaps android(though not sure, as with all the different versions it makes learning/loading applications a bit tricky) What is the most versatile language to start learning from chrome apps/android: Java would be excellent for android, but could I port it to a web app for chrome? (and its close to C#) Flash would work for a web app as I can just embed it into a html page (have done actionscript before, didn't care much for the IDE though), but would it also work on android? or I guess there is always C/C++ but haven't heard much about that, though I think it works for both (though C++ does interest me) Any advice would be excellent, thanks.

  • Do people in non-English-speaking countries code in English?

    - by Damovisa
    With over 100 answers to this question it's highly likely that your answer has already been posted. Please don't post an answer unless you have something new to say I've heard it said (by coworkers) that everyone "codes in English" regardless of where they're from. I find that difficult to believe, however I wouldn't be surprised if, for most programming languages, the supported character set is relatively narrow. Have you ever worked in a country where English is not the primary language? If so, what did their code look like? Edit: Code samples would be great, by the way...

  • Embarking on a website redevelopment and all developers pushing to move to ASP.NET 4.0

    - by Sue
    Our company is going through a website redevelopment / retooling exercise and we are not quite sure which direction to take. We are told that the website was built in ASP classic and that we should be moving to ASP.NET 4.0. Some developers refuse to do any work in the ASP classic framework citing the advantages of ASP.NET 4.0-- stability, compilation, language support. We are generally happy with our website as is. There are some kinks in the backend involving forms and there is little integration between the CRM of the website and any content management system. Does the move from ASP classic to ASP.NET 4.0 give major advantages to the integration between how content is created, and delivered to our customers?

  • How to return the relevant country domain in rich snippets pulled in from from Google Places?

    - by Baumr
    Background A site has multiple ccTLDs: example.com for people in the US, example.co.uk for UK users, example.de for Germans, etc. Googling for certain city keywords will return rich snippets with a list of Google Places: Problem When searching on Google Germany, the domain for US users (example.com) appears instead of the corresponding ccTLD (example.de) aimed at German users. This is not good user experience, as users would most likely like to book on a site localized for them (e.g. language and currency). Question What solutions are there? Is it possible to return different ccTLDs in rich snippets for Google searches in Germany/UK? If so, how? Ideas Stabs in the dark: Would implementing the hreflang annotation resolve this? (GWMT geotargeting is already set.) What about entering multiple corresponding URLs in the structured data markup? (As far as I know, Google Places accepts only a single website URL.)

  • Type classes or implicit parameters? What do you prefer and why? [closed]

    - by Petr Pudlák
    I was playing a bit with Scalaz and I realized that Haskell's type classes are very similar to Scala's implicit parameters. While Haskell passes the methods defined by a type class using hidden dictionaries, Scala allows a similar thing using implicit parameters. For example, in Haskell, one could write: incInside :: (Functor f) => f Int -> f Int incInside = fmap (+ 1) and the same function using Scalaz: import scalaz._; import Scalaz._; def incInside[F[_]](x: F[Int])(implicit fn: Functor[F]): F[Int] = fn.fmap(x, (_:Int) + 1); I wonder: If you could choose (i.e. your favorite language would offer both), what would you pick - implicits or type classes? And what are your pros/cons?

  • What are requirements for a successful SOA?

    - by Amir Rezaei
    I’m an EA in an organisation with 10000+ employees. Strategically we are heading towards SOA. Currently I’m researching about SOA’s and creating a road map and I have come over many blogs that talk about “SOA is dead”. We can all agree that SOA is not just web-services. The problem is that I have hard to find any information on the reason behind SOA-fail stories in enterprises. What went bad and what went right? My question is: What are common SOA mistakes in enterprises that make SOA fail in long term? Is the any best practice for SOA? What are the most important requirements for a successful SOA in an enterprise? It would be good feedback towards our SOA strategy in this organisation. I have tried to narrow down the question, but it’s hard due to the nature of the question.

  • Programming in the United States Airforce - How hard to get a job doing it? [closed]

    - by Holland
    I already know how to program. Been at it for a year; the language I've worked mostly with has been C++, and I'm currently studying x86 assembly programming, with the goal to move towards ARM assembly after I've finished with that. Thus, given my experience and knowledge, I'm curious to know if any "vets" around here have had any excursions in the military doing software/electrical engineering, and how hard it would be to actually get a job doing it - with someone who already has previous experience and knowledge regarding that field, however slight. By definition of "hard", in this context, I suppose I'd be referring to the required knowledge to actually be a "shoe-in" for both low level and high level software/hardware applications. I know hex fairly well, and enough to convert that hex to binary. I also have an ok knowledge of algorithms, such as Binary Search Tree, Linked List, etc. Everything I've learned so far has been self taught for the most part.

  • Error java.lang.OutOfMemoryError: getNewTla using Oracle EPM products

    - by Marc Schumacher
    Running into a Java out of memory error, it is very common behaviour in the field that the Java heap size will be increased. While this might help to solve a heap space out of memory error, it might not help to fix an out of memory error for the Thread Local Area (TLA). Increasing the available heap space from 1 GB to 16 GB might not even help in this situation. The Thread Local Area (TLA) is part of the Java heap, but as the name already indicates, this memory area is local to a specific thread so there is no need to synchronize with other threads using this memory area. For optimization purposes the TLA size is configurable using the Java command line option “-XXtlasize”. Depending on the JRockit version and the available Java heap, the default values vary. Using Oracle EPM System (mainly 11.1.2.x) the following setting was tested successfully: -XXtlasize:min=8k,preferred=128k More information about the “-XXtlasize” parameter can be found in the JRockit documentation: http://docs.oracle.com/cd/E13150_01/jrockit_jvm/jrockit/jrdocs/refman/optionXX.html

  • Extreme Optimization – Numerical Algorithm Support

    - by JoshReuben
    Function Delegates Many calculations involve the repeated evaluation of one or more user-supplied functions eg Numerical integration. The EO MathLib provides delegate types for common function signatures and the FunctionFactory class can generate new delegates from existing ones. RealFunction delegate - takes one Double parameter – can encapsulate most of the static methods of the System.Math class, as well as the classes in the Extreme.Mathematics.SpecialFunctions namespace: var sin = new RealFunction(Math.Sin); var result = sin(1); BivariateRealFunction delegate - takes two Double parameters: var atan2 = new BivariateRealFunction (Math.Atan2); var result = atan2(1, 2); TrivariateRealFunction delegate – represents a function takes three Double arguments ParameterizedRealFunction delegate - represents a function taking one Integer and one Double argument that returns a real number. The Pow method implements such a function, but the arguments need order re-arrangement: static double Power(int exponent, double x) { return ElementaryFunctions.Pow(x, exponent); } ... var power = new ParameterizedRealFunction(Power); var result = power(6, 3.2); A ComplexFunction delegate - represents a function that takes an Extreme.Mathematics.DoubleComplex argument and also returns a complex number. MultivariateRealFunction delegate - represents a function that takes an Extreme.Mathematics.LinearAlgebra.Vector argument and returns a real number. MultivariateVectorFunction delegate - represents a function that takes a Vector argument and returns a Vector. FastMultivariateVectorFunction delegate - represents a function that takes an input Vector argument and an output Matrix argument – avoiding object construction  The FunctionFactory class RealFromBivariateRealFunction and RealFromParameterizedRealFunction helper methods - transform BivariateRealFunction or a ParameterizedRealFunction into a RealFunction delegate by fixing one of the arguments, and treating this as a new function of a single argument. var tenthPower = FunctionFactory.RealFromParameterizedRealFunction(power, 10); var result = tenthPower(x); Note: There is no direct way to do this programmatically in C# - in F# you have partial value functions where you supply a subset of the arguments (as a travelling closure) that the function expects. When you omit arguments, F# generates a new function that holds onto/remembers the arguments you passed in and "waits" for the other parameters to be supplied. let sumVals x y = x + y     let sumX = sumVals 10     // Note: no 2nd param supplied.     // sumX is a new function generated from partially applied sumVals.     // ie "sumX is a partial application of sumVals." let sum = sumX 20     // Invokes sumX, passing in expected int (parameter y from original)  val sumVals : int -> int -> int val sumX : (int -> int) val sum : int = 30 RealFunctionsToVectorFunction and RealFunctionsToFastVectorFunction helper methods - combines an array of delegates returning a real number or a vector into vector or matrix functions. The resulting vector function returns a vector whose components are the function values of the delegates in the array. var funcVector = FunctionFactory.RealFunctionsToVectorFunction(     new MultivariateRealFunction(myFunc1),     new MultivariateRealFunction(myFunc2));  The IterativeAlgorithm<T> abstract base class Iterative algorithms are common in numerical computing - a method is executed repeatedly until a certain condition is reached, approximating the result of a calculation with increasing accuracy until a certain threshold is reached. If the desired accuracy is achieved, the algorithm is said to converge. This base class is derived by many classes in the Extreme.Mathematics.EquationSolvers and Extreme.Mathematics.Optimization namespaces, as well as the ManagedIterativeAlgorithm class which contains a driver method that manages the iteration process.  The ConvergenceTest abstract base class This class is used to specify algorithm Termination , convergence and results - calculates an estimate for the error, and signals termination of the algorithm when the error is below a specified tolerance. Termination Criteria - specify the success condition as the difference between some quantity and its actual value is within a certain tolerance – 2 ways: absolute error - difference between the result and the actual value. relative error is the difference between the result and the actual value relative to the size of the result. Tolerance property - specify trade-off between accuracy and execution time. The lower the tolerance, the longer it will take for the algorithm to obtain a result within that tolerance. Most algorithms in the EO NumLib have a default value of MachineConstants.SqrtEpsilon - gives slightly less than 8 digits of accuracy. ConvergenceCriterion property - specify under what condition the algorithm is assumed to converge. Using the ConvergenceCriterion enum: WithinAbsoluteTolerance / WithinRelativeTolerance / WithinAnyTolerance / NumberOfIterations Active property - selectively ignore certain convergence tests Error property - returns the estimated error after a run MaxIterations / MaxEvaluations properties - Other Termination Criteria - If the algorithm cannot achieve the desired accuracy, the algorithm still has to end – according to an absolute boundary. Status property - indicates how the algorithm terminated - the AlgorithmStatus enum values:NoResult / Busy / Converged (ended normally - The desired accuracy has been achieved) / IterationLimitExceeded / EvaluationLimitExceeded / RoundOffError / BadFunction / Divergent / ConvergedToFalseSolution. After the iteration terminates, the Status should be inspected to verify that the algorithm terminated normally. Alternatively, you can set the ThrowExceptionOnFailure to true. Result property - returns the result of the algorithm. This property contains the best available estimate, even if the desired accuracy was not obtained. IterationsNeeded / EvaluationsNeeded properties - returns the number of iterations required to obtain the result, number of function evaluations.  Concrete Types of Convergence Test classes SimpleConvergenceTest class - test if a value is close to zero or very small compared to another value. VectorConvergenceTest class - test convergence of vectors. This class has two additional properties. The Norm property specifies which norm is to be used when calculating the size of the vector - the VectorConvergenceNorm enum values: EuclidianNorm / Maximum / SumOfAbsoluteValues. The ErrorMeasure property specifies how the error is to be measured – VectorConvergenceErrorMeasure enum values: Norm / Componentwise ConvergenceTestCollection class - represent a combination of tests. The Quantifier property is a ConvergenceTestQuantifier enum that specifies how the tests in the collection are to be combined: Any / All  The AlgorithmHelper Class inherits from IterativeAlgorithm<T> and exposes two methods for convergence testing. IsValueWithinTolerance<T> method - determines whether a value is close to another value to within an algorithm's requested tolerance. IsIntervalWithinTolerance<T> method - determines whether an interval is within an algorithm's requested tolerance.

  • What programming languages have you taught your children?

    - by Dubmun
    I'm a C# developer by trade but have had exposure to many languages (including Java, C++, and multiple scripting languages) over the course of my education and career. Since I code in the MS world for work I am most familiar with their stack and so I was excited when Small Basic was announced. I immediately started teaching my oldest to program in it but felt that something was missing from the experience. Being able to look up every command with the IDE's intellisense seemed to take something from the experience. Sure, it was easy to grasp but I found myself thinking that a little more challenge might be in order. I'm looking for something better and I would like to hear your experiences with teaching your children to program in whatever language you have chosen to do so in. What did you like and dislike? How fast did they pick it up? Were they challenged? Frustrated? Thank you very much!

  • Project Coin: JSR 334 has a Proposed Final Draft

    - by darcy
    Reaching nearly the last phase of the JCP process, JSR 334 now has a proposed final draft. There have been only a few refinements to the specification since public review: Incorporated language changes into JLS proper. Forbid combining diamond and explicit type arguments to a generic constructor. Removed unusual protocol around Throwable.addSuppressed(null) and added a new constructor to Throwable to allow suppression to be disabled. Added disclaimers that OutOfMemoryError, NullPointerException, and ArithmeticException objects created by the JVM may have suppression disabled. Added thread safely requirements to Throwable.addSuppressed and Throwable.getSuppressed. Next up is the final approval ballot; almost there!

  • Using MVVM with Office365 and SharePoint 2010 REST API

    SharePoint 2010 Training: more information I love JavaScript – people had pronounced this language dead a long time ago. But just like a chicken – which you eat before it’s born and after it’s dead, JavaScript – is being eaten all over the technical world, long after it’s dead! How nice! The coolest thing about JavaScript is that, There is no need for separate ActiveX controls, it is part of HTML/Browser It can interact with other DOM elements very very naturally It’s safe. And  it’s backwards and future compliant. It is no surprise thus that a number of libraries have emerged helping us work with JavaScript. But, JavaScript is not like C#. Notably, it has some biggies missing. For instance, Read full article ....

  • Architecting multi-model multi-DB ASP.NET MVC solution

    - by A. Murray
    I have an ASP.NET MVC 4 solution that I'm putting together, leveraging IoC and the repository pattern using Entity Framework 5. I have a new requirement to be able to pull data from a second database (from another internal application) which I don't have control over. There is no API available unfortunately for the second application and the general pattern at my place of work is to go direct to the database. I want to maintain a consistent approach to modeling the domain and use entity framework to pull the data out, so thus far I have used Entity Framework's database first approach to generate a domain model and database context over the top of this. However, I've become a little stuck on how to include the second domain model in the application. I have a generic repository which I've now moved out to a common DataAccess project, but short of creating two distinct wrappers for the generic repository (so each can identify with a specific database context), I'm struggling to see how I can elegantly include multiple models?

  • GNOME Shell Overview animation is slow on my NVIDIA 320M

    - by AllanCaeg
    I'm running Ubuntu 10.10 on my MacBook Air 11" (late 2010 model 3,1). Compiz runs fine, as well as most of GNOME Shell's animations. The animation for switching to and from GNOME Shell overview is just very slow. Unfortunately, it's the most common animation on Shell. I already applied cd ~/gnome-shell/source/gnome-shell curl http://bugzilla-attachments.gnome.org/attachment.cgi?id=157326 > shell-animations-nvidia.patch git am shell-animations-nvidia.pat that I found from http://live.gnome.org/GnomeShell/SwatList , but the issue's still here. How do I fix this? EDIT: Apparently, it's an NVIDIA driver bug, which has something to do with the message tray. Is this correct? How do I go around this issue?

  • Why PHP Function Naming so Inconsistent?

    - by Shamim Hafiz
    I was going through some PHP functions and I could not help notice the following: <?php function foo(&$var) { } foo($a); // $a is "created" and assigned to null $b = array(); foo($b['b']); var_dump(array_key_exists('b', $b)); // bool(true) $c = new StdClass; foo($c->d); var_dump(property_exists($c, 'd')); // bool(true) ?> Notice the array_key_exists() and property_exists() function. In the first one, the property name(key for an array) is the first parameter while in the second one it is the second parameter. By intuition, one would expect them to have similar signature. This can lead to confusion and the development time may be wasted by making corrections of this type. Shouldn't PHP, or any language for that matter, consider making the signatures of related functions consistent?
