Looking for some implementation ideas here. I am trying to design a custom polling system for my school, to allow teachers to give students polls to take. I have a Poll model, Question model (with a foreignkey to Poll model), and Choice model (with a foreignkey to the Question model). What I need to be able to do is allow whoever is ad...

Hi everyone, I was wondering if anyone could suggest to me how to implement this loop in the following pseudocode: 8: loop 9: while f[0] = 0 do 10: for i = 1 to N do 11: f[i ¡ 1] = f[i] 12: c[N + 1 - i] = c[N - i] 13: end for 14: f[N] = 0 15: c[0] = 0 16: k = k + 1 17: end while 18: if deg(f) = 0 then 19: go...

Now I am trying to use MPI_Sendand MPI_Recv to pass best found solutions among several processes. The best solutions found in each process are supposed to pass to the control process what stores all best solutions and send to other processes when required. My question is how to implement it? For example, once process 1 find a new best, i...
I am looking for a really simple database implementation; basically one with no complex parsing SQL engine. What I am looking for is something demonstrating B+ trees and ACID storage (Suitable for educational purposes). What I have found up-till now form my current searches was hamster-db. I am looking for something even simpler with a s...
The PHP array is one of the language's core features IMHO. It is sparse, allows multi-typed keys in the same array, and supports set, dictionary, array, stack/queue and iterative functionality. BUT after working with PHP for a while now, I've found that quite a few of the array_* functions are much slower than you'd think at first glanc...
I have an own Tree object implemented in PHP. Say we have a tree like: Root |_ Folder 1 |_ Folder 2 |_ Subfolder 1 I can access Subfolder 1 like this: $sf1 = $Tree->NavigateTo("Folder 2/Subfolder 1") And $sf1 will hold the Subfolder 1 node. I want to implement a GetParentNode() method, so that $parent = $sf1->GetParent...
If we have a class that inherits from multiple interfaces, and the interfaces have methods with the same name, how can we implement these methods in my class? How we can specify that which method of which interface is implemented? ...
I am a C# programmer but I have to work with some VB.Net code and I came across a situation where I have two methods on an interface with the same name but different method parameters. When I attempt to implement this interface in a class, VB.Net requires explicitly declaring "Implements MethodName" after the method signature. Since both...
Hey everyone, I'm a college senior with my first real job opportunity (exciting). I'm at the stage now where they need to see a programming example, and they gave me the task of implementing a random number generator service in Java, with two different implementations (one using the built-in stuff and another of my choice). The code is t...
Hello all. My first post here so be please be kind :) I searched SO before posting but I couldn't find an answer (it's possible that my search wasn't the best though) I'm starting to learn C++ and as an exercise decide to implement a simple LinkedList class (Below there is part of the code). I have a question regarding the way the cop...
Does anyone have a quick snippet or direction of how i would check to see if a given class supports the >, = and < operators? Given an object passed in, I am looking for code that implements the following logic: If GetType(someObj).SupportsScalarComparisons() Then ... I don't know if this is a case for Reflection, or ? Thanks in ad...
I have a interface member like this. AppInterface.cs ObjLocation[] ArrayLocations { get; } App.cs public ObjLocation[] ArrayLocations { get { return **something**; } } I dont know how to complete it, Or there is another way to implement the array members. Then It...
I'm attempting to develop an Interceptor framework (in C#) where I can simply implement some interfaces, and through the use of some static initialization, register all my Interceptors with a common Dispatcher to be invoked at a later time. The problem lies in the fact that my Interceptor implementations are never actually referenced by...
Hello Everyone, I would like to know do we have any webdav protocol implementation in c or c++. Thank You in advance.. ...
This questions involves 2 different implementations of essentially the same code. First, using delegate to create a Comparison method that can be used as a parameter when sorting a collection of objects: class Foo { public static Comparison<Foo> BarComparison = delegate(Foo foo1, Foo foo2) { return foo1.Bar.CompareTo(fo...
