  • python how to find the median of a list

    - by user3450574
    I'm trying to write a function named median that takes a list as an input and returns the median value of the list. I'm working with Python 2.7.2 The list can be of any size and the numbers are not guaranteed to be in any particular order. If the list contains an even number of elements, the function should return the average of the middle two. This is the code I'm starting with: def median(list): print(median([7,12,3,1,6,9]))

  • C++ error message output format

    - by sub
    If I want to trigger an error in my interpreter I call this function: Error( ErrorType type, ErrorSeverity severity, const char* msg, int line ); However, with that I can only output Name error: Undefined variable in line 1 instead of Name error: Undefined variable 'someVariableName' in line 1 I'm working entirely with strings (except for the error messages as they all are constant at the moment), so sprintf won't work. What is the best way to create an efficient error function that can output a constant message combined with a string that describes which object, e.g.: a non-existing variable, triggered the error?

  • How to allocate memory in another process for windows mobile

    - by Serafeim
    I'd like to read the contents of another process listview control in windows mobile. To do this, I need a pointer to some free memory to that process in order to put the values there (and then read them from my process). This can be done in normal Windows or Win32 with the VirtualAllocEx function. However, this function is not supported in windows mobile ! Can you recommend me a way to allocate that memory?

Any idea why? Where is it going after the event is handled?

How can I do this?

  • How to implement tail calls in a custom VM

    - by DeadMG
    How can I implement tail calls in a custom virtual machine? I know that I need to pop off the original function's local stack, then it's arguments, then push on the new arguments. But, if I pop off the function's local stack, how am I supposed to push on the new arguments? They've just been popped off the stack.

  • Lambda functions

    - by Oden
    Hey, I'm really interested in the way of using lambda functions. Does it make sense to use them in a high-level programming language? If yes, why? Is this really just a function embedded in a function (like this) or is there more behind?

  • Javascript: Static member variable containing object instances

    - by tom
    I have the following: function Preferences() { } Preferences.players = { 'player1': new Player() } players is a static member variable of Preferences and I'm trying to make it an object containing an instance of a Player. However, it doesn't appear to let me do this. It seems like it will allow me to define players if I make it a non-static member variable however. Like so: function Preferences() { var players = { 'player1' : new Player() } } Is it possible to create a static member variable containing instances of an object in JS?

  • Backbone View: Inherit and extend events from parent

    - by brent
    Backbone's documentation states: The events property may also be defined as a function that returns an events hash, to make it easier to programmatically define your events, as well as inherit them from parent views. How do you inherit a parent's view events and extend them? Parent View var ParentView = Backbone.View.extend({ events: { 'click': 'onclick' } }); Child View var ChildView = ParentView.extend({ events: function(){ ???? } });

  • What jquery rails 3 tutorial has worked well for you?

    - by finneycanhelp
    Hi! I have looked at several tutorials involving rails 3 and jquery. The tutorial at http://www.blog.bridgeutopiaweb.com/post/how-to-use-jquery-for-rails-3/ looked promising. However, I get the errors of document.on is not a function and $("a[data-remote=true]").livequery is not a function I get the feeling that I should look at another tutorial or just use jquery raw and not install a ruby gem for jquery. Any advice? Thanks!
