I find that I often have to maintain a singleton primarily to hold an array that is sometimes persisted between user sessions, that should have only one class of items, and that sometimes needs to be ordered. I got tired of writing the same boilerplate over and over so came up with this. I'd welc...
I wanted to make a button that goes to the top of the page but only appears when you're not at the top. There are probably libraries that already do this, but I wanted to make it myself and after some tinkering the following is what I came up with.
There is an occasional annoyance from quickly s...

PROBLEM: Suppose x and y are variables of type double. Write a program that asks the user for the value of x, where x can be a negative or positive number. Set y to x if x is positive (not negative) and 0 otherwise.
The part where I get confused is how do you set y equal to x without definin...
I've been designing a dynamic graph to improve my understanding of C++11. The dynamic aspect means it could represent the hyperlink structure of internet, with node deletion corresponding to removing dead links.
I'd be grateful for a review of coding style/design patterns/optimization.

Purpose
I came across this relatively simple question on HackerRank regarding finding missing values across two Lists. I took a fairly straight-forward approach, but is there a "better" / "slicker" way of implementing a solution?

Introduction
All too often I find myself wanting to allow only a certain list of characters to be written to stdin, and only recently did I actually bother to implement it. In Python, of all languages!
Essentially, this module provides a few APIs that allow a very tailored approach to ...
![I searched my .bash_history for the line with the highest ratio of special characters to regular alphanumeric characters, and the winner was: cat out.txt | grep -o "\\\[[(].*\\\[\])][^)\]]*$" ... I have no memory of this and no idea what I was trying to do, but I sure hope it worked.](http://imgs.xkcd.com/comics/backslashes.png "I searched my .bash_history for the line with the highest ratio of special characters to regular alphanumeric characters, and the winner was: cat out.txt | grep -o \"\\\[[(].*\\\[\])][^)\]]*$\" ...

For the functions included here, I have taken the advice of the previous answer and incorporated it in the restructure, but am still experiencing huge latency of about 2 seconds per computer record.

I've created a function that sorts strings using selection sort, but I want to know if I can do this without changing the original strings. For example, if I try to sort an array string[4] = {"two","One","four","Three"}, it prints One, Two, Three, Four, but I want it to print {One, two, Three, f...
I'm creating my own application exception types so I could catch them higher in the call stack and take specific action. I'm looking to get feedback on the latest exception I've written for two reasons:
I'm using the Exception snippet from Visual Studio 2013, and am wondering if it is any good ...I've created a class called Box that is pretty much what it sounds like. I want to sort these box objects, and I have created a function to do so.
void boxSort(Box array[], int size) {
Box temp;
bool swap;
do {
swap = false;
for(int count=0; count<(size-1); count++)...
There is understandably a lot of emphasis on sanitizing user input handed off to PHP on a Web Server and numerous opinions on doing it.
Can U please confirm there is no security problems with the following PHP code which may compromise the server through an exploit:

When I have an many to many relationship, never link them in the classes like this :
class Student {
private Collection<Act> acts;
}
class Act {
private Collection<Student> students;
}
The reason behind this is because I don't want to load more then needed.
What do I mean with this :

I have written the API for instant php message. This API is used in an android chat app. But this API is sending and receiving the message little bit late. I am not sure where I am going wrong. Here is the code which I wrote

I'm a Java guy in a JavaScript world, and I'm used to certain things about Java Strings that just aren't there for in JavaScript. Some of this I can accept, for example Strings are freaking everywhere for some reason.
Now I realize this could be simply implemented with return this.indexOf(needl...
The statement is as follows :
The sequence of triangle numbers is generated by adding the natural numbers.
So the 7th triangle number would be 1 + 2 + 3 + 4 + 5 + 6 + 7 = 28.
The first ten terms would be:
1, 3, 6, 10, 15, 21, 28, 36, 45, 55, ...
Let us list the factors of the first seven tr...

So I've got this key value store with a legacy object, PersoonInstellingenObject, which has a key and a value and a id. The ID is never exposed, we use the key instead, but multiple values with the key can exist. The personalSettingsService does all the database stuff via layers upon layers upon ...

This is a unity3D script I wrote for my game to control a character.
I don't consider myself a highly-skilled coder, so I come here to ask for suggestions.
Is my code clean enough? How can I improve my coding style and pattern?
Thanks!

I have a list:
my_list = [1, 2, 3, 4, 5]
How can I multiply each element in my_list by 5? The output should be:
[5, 10, 15, 20, 25]

When I post a question, obviously I can't leave it alone and I google a lot afterwards.
Can't say much about your use of Lists and such, but what you've got there is not very RESTful. When all I want to do is delete a single value from a large multi-valued key, then why do I need to send the ent...
