• What is SIP trunking?

  - by hypnocode

  Can someone explain to me in plain English what SIP trunking is, please? I've read about it on Google, but I don't really grasp it yet. Does it allow a VoIP call to be placed outside of the LAN? So if you had Asterisk setup as the PBX, then IP calls could be made outside of the network? Am I close or am I just saying stupid words?

• jquery binding multiple events, and pass data

  - by mkoryak

  I know we can have this in 1.4: $("a").bind({ click : clickFn, mouseover: mouseFn }); and that is nice and i would like to use it, but it seems like there is no way to pass extra data to events bound this way, it needs to be done the 'old way': $("a").bind("click", {"some":"data"}, clickFn); Question: how can i pass the extra data to my event call backs and bind multiple events in a single bind at the same time?

• What is the Action returned by the subscribe parameter of IObservable.Create actually for?

  - by James Hay

  The method definition of IObservable.Create is: public static IObservable<TSource> Create<TSource>( Func<IObserver<TSource>, Action> subscribe ) I get that the function is called once the observable is subscribed to, where by I can then call OnNext, OnError and OnComplete on the observer. But why do I need to return an Action from the subscibe parameter and when will it actually be called?

  - by Ike

  Hello there, I'm hoping someone could help me with a quick point in the right direction. ALL I NEED is the Outlook folder browser dialog call. I am developing some plugins for Outlook using C# and this is a crucial part for both plugins. Hopefully, it is like a standard DialogResult that passes back folder information (selected folder) so that I can use this info for further processing. Can anyone help me? Thanks in advance.

• How do I unit test the methods in a method object?

  - by Sancho

  I've performed the "Replace Method with Method Object" refactoring described by Beck. Now, I have a class with a "run()" method and a bunch of member functions that decompose the computation into smaller units. How do I test those member functions? My first idea is that my unit tests be basically copies of the "run()" method (with different initializations), but with assertions between each call to the member functions to check the state of the computation. (I'm using Python and the unittest module.)

• polymorphism and interfaces

  - by mixm

  if i have two classes x and y, both extend class w. and x implementing interface z. if i have methods doSomething(w object) and doSomething(x object), what would happen if i call doSomething(x)? edit: im implementing this on java, more specifically on android. im asking this because some classes which implement a specific interface mostly does the same thing when doSomething() is called. but there are special cases which i would like to single out.

• 'Locale' configuration and its relationship with Windows API

  - by The Kaykay

  Can the locale configuration of a system OR the keyboard type configuration of that system in anyway affect which API is called at the Kernel level? To be specific, if a program is invoking 'CreateFile()' API then the windows API documentation says that the call gets delegated to either CreateFileA or CreateFileW. If that program is being run on a system present in China with a Chinese Keyboard then which of the two functions will be called?

• how to define a structural type that refers to itself?

  - by IttayD

  I want to create a method sum that I can call on different types, specifically sum(1,2). def sum[A](a1: A, a2: A) = a1 + a2 This fails because the compiler can't tell if A has a method '+' I tried to define a structural type: type Addable = {def +(a: Addable)} This fails because of an illegal cyclic reference How can I achieve this in a type safe way without requiring A to extend a specific trait?

• JSP application scope objects in Java library

  - by FrontierPsycho

  I am working on a preexisting web application built with JSP, which uses an external Java library. I want to make some JavaBeans that were instantiated with jsp:useBean tags available to the Java code. What would be a good practice to do that? I suppose I can pass the objects in question to every function call that requires them, but I'd like to avoid that.
