• On Wireframes, Prototypes and E-Citizenship

  Here are some thoughts and arguments on why using wireframes and prototypes to engage more citizens in political life. The use of wireframes and prototypes could enhance E-democracy.

• Implementing prototypes OR instantiating class objects

  - by intuited

  I'm wondering how to implement prototypal inheritance in Python. It seems like the way to do this would be to either use a metaclass to cause instantiations to actually be classes, rather than objects, or use some magical powers to transform an existing object into a class. The second method would seem to be more flexible, in that it could be…

• Facebook totalement hors-service cette nuit, un employé aurait dévoilé des prototypes par erreur

  Facebook totalement hors-service cette nuit, un employé aurait dévoilé des prototypes par erreur Hier soir (à partir de 22h15 heure française), Facebook a été hors service pendant près de 30 minutes. Le site n'a pourtant subi aucune attaque extérieure. En fait, il a été mis hors ligne par la firme elle-même. En cause ? Lors du passage au nouveau…

• Creating WPF Prototypes with SketchFlow

  Prototyping with Sketchflow transforms what was once a frustrating and time-consuming chore. With SketchFlow, WPF prototypes can be created and changed with amazing ease. SketchFlow is WPF's secret weapon. Well, it was secret until Michael Sorens produced this article.

• Agile language for 2d game prototypes?

  - by instanceofTom

  Occasionally ( read: when my fiancé allows ) I like to prototype different game or game-like ideas I have. Usually I use Java or C# (not xna yet) because they are the languages I have the most practice with. However I would like to learn something more suited to agile development; a language in which it would be easier to knock out quick…

• How can pointers to functions point to something that doesn't exist in memory yet? Why do prototypes have different addresses?

  - by Kacy Raye

  To my knowledge, functions do not get added to the stack until run-time after they are called in the main function. So how can a pointer to a function have a function's memory address if it doesn't exist in memory? For example: using namespace std; #include <iostream> void func() { } int main() { void (*ptr)() = func; …

• Javascript functional inheritance with prototypes

  - by cdmckay

  In Douglas Crockford's JavaScript: The Good Parts he recommends that we use functional inheritance. Here's an example: var mammal = function(spec, my) { var that = {}; my = my || {}; // Protected my.clearThroat = function() { return "Ahem"; }; that.getName = function() { return spec.name; …

• What common programming problems are best solved by using prototypes and closures?

  - by vemv

  As much as I understand both concepts, I can't see how can I take advantage of JavaScript's closures and prototypes aside from using them for creating instantiable and/or encapsulated class-like blocks (which seems more of a workaround than an asset to me) Other JS features such as functions-as-values or logical evaluation of…

• constructors and inheritance in JS

  - by nandinga

  Hi all, This is about "inheritance" in JavaScript. Supose I create a constructor Bird(), and another called Parrot() which I make to "inherit" the props of Bird by asigning an instance of it to Parrot's prototype, like the following code shows: function Bird() { this.fly = function(){}; } function Parrot() { …

• Helper functions & prototype methods to replace heavy frameworks?

  - by Rob

  All frameworks aside, what are some of the common helper functions/prototype methods you use on a daily basis? Please note I am not arguing against frameworks. I've simply found that the majority of what I do on a daily basis can, most often, be done with a few dozen Array, String and Element.prototype methods. With…

• c++ inline functions

  i'm confused about how to do inline functions in C++.... lets say this function. how would it be turned to an inline function int maximum( int x, int y, int z ) { int max = x; if ( y > max ) max = y; if ( z > max ) max = z; return max; }

• Any way in C++ to forward declare a function prototype?

  - by jsyjr

  I make regular use of forward class declarations and pointers to such classes. I now have a need to pass a function pointer through a number of layers. I would prefer to include the header that declares my function pointer's prototype only into the module that dereferences a function pointer rather than into each…

• What are the benefits of a classical structure over a prototyple one?

  - by Rixius

  I have only recently started programming significantly, and being completely self-taught, I unfortunately don't have the benefits of a detailed Computer science course. I've been reading a lot about JavaScript lately, and I'm trying to find the benefit in classes over the prototype nature of JavaScript. The…

• Why does this C program compile?

  - by AdmiralJonB

  I've just come across someone's C code that I'm confused as to why it is compiling. There are two points I don't understand. First, the function prototype has no parameters compared to the actual function definition. Secondly, the parameter in the function definition doesn't have an type. #include…

• Must declare function prototype in C?

  - by Mohit Deshpande

  I am kind of new to C (I have prior Java, C#, and some C++ experience). In C, is it necessary to declare a function prototype or can the code compile without it? Is it good programming practice to do so? Or does it just depend on the compiler? (I am running Ubuntu 9.10 and using the GNU C Compiler,…

• Generate 300 lists of 12 numbers between 1 and 33 without repeats in excel

  I am conducting a study in which each of the 300 participants are rating 12 prototypes each. We have 33 prototypes in total. How would I generate 300 lists each containing 12 random prototypes from the 33 in excel ensuring that no list contains a duplicate and all prototypes appear at least 100…

• Can Visual Studio manage function prototypes for me in C++ header files?

  - by Gibybo

  In C++, the common practice is to declare functions in header files and define them in cpp files. This leads to always having two copies of every function's prototype. Then whenever I want to change a function's name/return value/parameter, I have to manually change it in both…
