  • Should I cache the XRDS file returned in openid?

    - by Joseph
    In the initial part of the openid sequence, I request the OP (e.g. Yahoo.com) and get back the XRDS file which tells me the actual URL I need to use for the rest of the openid process. So, can I cache this initial file. E.g. if I have hundreds of users using a Yahoo openid, I would only have to do the initial fetch once every hour?

  • [Javascript] Prevent an element from being the target in a document mouseover

    - by Sander
    I'm building an firebug-like inspection tool for my page. When the mouse enters an element, the element should be highlighted. Now I'm creating an element which I position absolute on top of the target element, this however means the next mousemove event (which is bound to the document) will fire with the actual "highlight element" as the target. Is there a way to prevent the "highlight element" from being the target element in the mousemove event? The element already has a transparant background.

  • Example of moving from MySQL to NoSQL?

    - by OverTheRainbow
    Hello, For a Facebook-like site, ie. which is write-intensive and delivers user-customized pages, I'd like to build a prototype to investigate whether the document-centric NoSQL architecture would be a good alternative to sharding and reduce the load on the single master (+ multiple slaves) that we currently use and is the bottleneck. Does someone know of a good article that would give actual, simple examples of going from a relational layout in MySQL to a NoSQL layout? Thank you.

  • How to parse HTML from JavaScript in Firefox?

    - by hmp
    What is the best way to parse (get a DOM tree of) a HTML result of XmlHttpRequest in Firefox? EDIT: I do not have the DOM tree, I want to acquire it. XmlHttpRequest's "responseXML" works only when the result is actual XML, so I have only responseText to work with. The innerHTML hack doesn't seem to work with a complete HTML document (in <html</html). - turns out it works fine.

  • How to stay connected to the programming community?

    - by Anton
    I often find myself detached from the programming community and I generally find out about all the "cool" things that are happening after they have already happened. So my question is how do you stay connected and up to date with the programming community? Podcasts, blogs, meet ups, conventions, twitter, talking with your co-workers whatever it may be that keeps you connected. Please provide actual examples of which blogs, talks, etc you use.

  • Get ahold of session in command object in Grails

    - by UltraVi01
    How can I get the session from within a command object? I have tried: import org.springframework.security.context.SecurityContextHolder as SCH class MyCommand { def session = RCH.currentRequestAttributes().getSession() } This throws java.lang.IllegalStateException: No thread-bound request found: Are you referring to request attributes outside of an actual web request, or processing a request outside of the originally receiving thread? If you are actually operating within a web request and still receive this message, your code is probably running outside of DispatcherServlet/DispatcherPortlet: In this case, use RequestContextListener or RequestContextFilter to expose the current request.

  • How should I structure my repository classes?

    - by Innogetics
    I am new to DDD. In my mini-project, I have a structure that looks like this (different from the actual names): EntryClassificationGroup EntryClassification Entry EntryType Should I have just one repository class for all these 4 entities, since they are all related? Or should I have individual repositories for each one?

  • Visual Studio 2010 and Test Driven Development

    - by devoured elysium
    I'm making my first steps in Test Driven Development with Visual Studio. I have some questions regarding how to implement generic classes with VS 2010. First, let's say I want to implement my own version of an ArrayList. I start by creating the following test (I'm using in this case MSTest): [TestMethod] public void Add_10_Items_Remove_10_Items_Check_Size_Is_Zero() { var myArrayList = new MyArrayList<int>(); for (int i = 0; i < 10; ++i) { myArrayList.Add(i); } for (int i = 0; i < 10; ++i) { myArrayList.RemoveAt(0); } int expected = 0; int actual = myArrayList.Size; Assert.AreEqual(expected, actual); } I'm using VS 2010 ability to hit ctrl + . and have it implement classes/methods on the go. I have been getting some trouble when implementing generic classes. For example, when I define an .Add(10) method, VS doesn't know if I intend a generic method(as the class is generic) or an Add(int number) method. Is there any way to differentiate this? The same can happen with return types. Let's assume I'm implementing a MyStack stack and I want to test if after I push and element and pop it, the stack is still empty. We all know pop should return something, but usually, the code of this test shouldn't care for it. Visual Studio would then think that pop is a void method, which in fact is not what one would want. How to deal with this? For each method, should I start by making tests that are "very specific" such as is obvious the method should return something so I don't get this kind of ambiguity? Even if not using the result, should I have something like int popValue = myStack.Pop() ? How should I do tests to generic classes? Only test with one generic kind of type? I have been using ints, as they are easy to use, but should I also test with different kinds of objects? How do you usually approach this? I see there is a popular tool called TestDriven for .NET. With VS 2010 release, is it still useful, or a lot of its features are now part of VS 2010, rendering it kinda useless? Thanks

  • Is is possible to create a factory class in PHP?

    - by user198729
    Like the BeanFactory in java: In the much more common case where the BeanFactory itself directly creates the bean by calling its constructor (equivalent to Java code calling new), the class attribute specifies the class of the bean to be constructed. In the less common case where the BeanFactory calls a static, so-called factory method on a class to create the bean, the class attribute specifies the actual class containing the static factory method. Note:it's not the factory method

  • Does knowing a Natural Language well help with Programming?

    - by Earlz
    We all hear that math at least helps a little bit with programming. My question though, does English or other natural language skills help with programming? I know it has to help with technical documentation, but what about actual programming? Are certain constructs in a programming language also there in natural languages? Does knowing how to write a 20 page research paper help with writing a 20k loc programming project?
