Is this a valid and safe use of using .NET's SpinLock?
public static class SingleRandom
{
private static Random random;
private static bool gotLock;
private static SpinLock spinLock;
static SingleRandom()
{
random = new Random();
}

I've an array where each element is either one less or one greater than the preceding element. I've to search an element in it in less than O(n) time. I've implemented it like this:

if (i > arr.length - 1 || i < 0) {

So, I make Regex to find any url on site, uses php.
Reg = new System.Text.RegularExpressions.Regex("((http|https)://([a-zA-Z0-9-]{1,}[/]?))?[/]?([a-zA-Z0-9-]{1,}[.](php|html))((/[a-zA-Z0-9-]{1,}){1,}[/]?){0,}([?]([a-zA-Z0-9]{1,}=[a-zA-Z0-9\"><();/.,]{1,}&?){1,})?");

Using regex to match a URI is never a good solution... as you have discovered, you now have two problems (the base problem, and the regex problem).
In this case, you should use the language features to help you.... (bear in mind I am a Java person, so I may have some syntax errors)....

I've just now noticed the missing diamond on his profile, along with this:
There's no announcement on Meta, and this just seems like an abrupt change. I'm not sure how long ago this was, either. But I probably should've suspected something when it seemed to take a tad longer for my recent mo...
I have some code and when it executes, it throws a NullReferenceException, saying, "Object reference not set to an instance of an object.".
What does this mean, and what can I do about it?
The current code solves the issue I had when trying to use Property Injection.
Problem: Every module must use Constructor Injection because of a circular reference that occurs when not using Constructor Injection with my factories and trying to use Property Injection
Reason: A module requires a...

This looks pretty messy. I need a check an input for seat, but I can't guarantee it has a value (one may not be chosen for example). If the seats aren't in a certain color it goes to seat basic(1), otherwise seat premium (2)
var seat = $("input[id*=" + seatPrefix + "]");

I have a hierarchy like:

share/index.html is on a sub-domain (http://www.share.foo.com instead of http://www.foo.com).
I would like to access myImage.png from both domains.
So far, I've only been able to find one way to manage this. From index....
I just learned the quicksort algorithm and tried to implement it, but it feels dirty:

#include <stdlib.h>

void quicksort(int list[], int low, int high)

if(low >= high)
return;
else
{
int pivot = low, i = low, j = high;

I recently finished my attempt of implementing the Huffman algorithm in Java to create a string and file compressor/decompressor. Whilst I am pleased with the results, compression seems a little slow (compared to the much faster decompression).
I am also looking for ways to increase the compres...
