  • Why do encodeXxx methods in UIComponent accept FacesContext parameter?

    - by Roman
    I haven't ever before created custom components in JSF so I've noticed only now that methods like encodeBegin(), encodeEnd() etc accept FacesContext parameter. FacesContext instance can usually be received with FacesContext.getCurrentInstance(). So, I wonder whether these methods have FacesContext parameter just for convenience or some different objects can be passed there (maybe from external resources..). If the latter is possible then could you give an example pls.

  • web applications tend to have a admin panel?

    - by ajsie
    i wonder if large web applications like twitter and facebook have admin panels to handle CRUD for users, posts, images, themes and so on just like in CMS like drupal? so programmers have to code the front for the regular users AND back for the administrators? if i develop an web application is it recommended that i also code the admin part? or is it unnecessary since i can handle all directly in mysql and by editing php scripts directly? share your thoughts! thanks

  • iPhone apps for company-internal use - possible?

    - by Michael Stum
    I hope this is still programming related, as SuperUser doesn't seem the appropriate place. Basically I wonder if it is possible to have Applications that are internal to a company on the iPhone? That is something like a companion Application to an Intranet (when Safari and Mail just don't cut it) which wouldn't make sense on the AppStore (and likely wouldn't get approved anyway). Is something like that possible (without Jailbreaking or doing anything else that Apple doesn't normally want)?

  • SAS on OS X any way to run without working within virtual machine?

    - by user309284
    I would like to edit and submit SAS code from emacs (aquamacs) on OS X to SAS running on Vista (through Parallels). Any idea how to do this? I like to do everything through one place and it is really annoying to work within the windows emulator. I have run SAS from a linux server through aquamacs but wonder if something similar can be done locally. Any ideas?

  • Sort months ( with strings ) algorithm

    - by Oscar Reyes
    I have this months array: ["January", "March", "December" , "October" ] And I want to have it sorted like this: ["January", "March", "October", "December" ] I'm currently thinking in a "if/else" horrible cascade but I wonder if there is some other way to do this. The bad part is that I need to do this only with "string" ( that is, without using Date object or anything like that ) What would be a good approach?

  • If-else-if versus map

    - by perezvon
    Hi, Suppose I have such an if/else-if chain: if( x.GetId() == 1 ) { } else if( x.GetId() == 2 ) { } // ... 50 more else if statements What I wonder is, if I keep a map, will it be any better in terms of performance? (assuming keys are integers)

  • getting IllegalAccessException when accessing a protected method from parent from inner class

    - by EnToutCas
    I got a very weird problem and a weird solution: class Parent { protected void aProtectedMethod() { doSomething(); } } class Child extends Parent { void anotherMethod() { new SomeInterface() { public void interfaceMethod() { aProtectedMethod(); } }; } } When child.anotherMethod() is run, I got IllegalAccessException at myProtectedMethod(), saying my inner class doesn't have access to the Parent class... However, if I add: protected void aProtectedMethod() { super.aProtectedMethod(); } in my Child class, everything is fine... I wonder why this is?

  • Which is clearer form: if(!value) or if(flag == value) ?

    - by CodexArcanum
    I understand this is a subjective question, so I apologize if it needs to be closed, but I feel like it comes up often enough for me to wonder if there is a general preference for one form over the other. Obviously, the best answer is "refactor the code so you don't need to test for falsehood" but sometimes there's no easy way to do so and the "else" branch is simply to continue processing. So when you must have an "if not false" construct, which is the preferred standard: The not operator if(!value) Or the test for false if(value == false)

  • How do "modern JVMs" differ from older JVMs?

    - by Lord Torgamus
    Here's a phrase that I heard a lot throughout high school and university computer science classes: "That's not an issue for modern JVMs." Usually this would come up in discussions about overall performance or optimization strategies. It was always treated as a kind of magical final answer, though, as if it makes issues no longer worth thinking about. And that just leads me to wonder: what are the differences between the prototypical "modern JVM" and older JVMs, really?

  • Managing User Profiles with PHP/MySQL for Beginners

    - by serhio
    I am beginner in PHP/MySql and would develop a simple site that has user management. I like the idea of using OpenId's (like stackoverflow uses). I wonder from where to start? What should I read? I have not much time so probably will net enter in all details of PHP user session management, this because I search something like User profiles management in PHP for dummies 8D Environment: Linux OS Apache 2.2.15 MySQL 5.1.41 PHP 5.2.13 cPanel 11.25.0

  • Improving MVP in Scala

    - by Alexey Romanov
    The classical strongly typed MVP pattern looks like this in Scala: trait IView { } trait Presenter[View <: IView] { // or have it as an abstract type member val view : View } case class View1(...) extends IView { ... } case object Presenter1 extends Presenter[View1] { val view = View1(...) } Now, I wonder if there is any nice way to improve on it which I am missing...
