I am working on a program in which 10000 random no repeat numbers are selectively sorted into ascending order.
I have written the following code:

public class Sorting {
public static void main (String[] args){
//Here, we initiate an array with the integers...
I am working through Kernighan and Ritchie to brush up on my C skills, so I thought I would invite critiques of my code.
Here is my Hex-to-int function:

int i;
int msnibble;
int digits;
const int nibbles[] = {'\x0','\x...
I build phone apps and I use JSON a lot in my APIs.
The problem is sometimes I don´t know how how to format the JSON data.
For example iOS UITableView takes NSArray as datasource.

"contact_id": [
"455",
"464"
],
"contact_name": [
"Administrator",

I am following up on my previous question here
Problem Statement:-
I was ask this interview question recently.. I was able to come up with the below code only which runs in O(k log n)-
Given k <= n sorted arrays each of size n, there exists a data structure requiring O(kn) preprocessing time ...
I've written a function that works fine, but being new to jQuery, I'd like to know if there's a more cleaner way of writing it. Anything advice would help; just trying to learn!

var $link2 = $('.row.nav li a.stylist');

function displayContent() {
// put all links together
var $links = $('.row.nav li a').filter(".bio,.stylist,.contact");
var $content = $('#text-content')

The following shows that "0" is false in Javascript:
>>> "0" == false
true

true
So why does the following print "ha"?

I'm far from a Java expert, but a few things jumped out at me
You forgot to close the reader (br).
Do not close the streams inside of the try. What happens if an exception gets thrown before the close commands are reached? You need a finally block. Or, better yet, if you're using Java 7 or ...
For example:
void thisIsAnExample(Hello* bye, char* name, int num, in* arr, int* sum){
GoodBye x;;
x.funName = name;
.
.
.
Just a few things that stick out to me:
What is cons? Don't you mean Node? At first I thought it was just a short form of constructor, but it appears to be corresponding to a node.
I'd strongly recommend using a different variable name than new. Although this is C and not C++, this could sti...

You can get rid of the <type_traits> header but replacing your std::enable_if by a bool template specialization:
template <::std::size_t, ::std::size_t, bool>
struct expand_indices_impl;
template <::std::size_t A, ::std::size_t B>
struct expand_indices:
expand_indices_impl<A, B, A==B>
{};
...
Things that I'm not sure about:
Whether this works in all use cases - alongside routing and within templates etc

Your mailer is vulnerable to a header-splitting attack! (Also known as a CRLF-injection attack.)
Basically, if one of the fields contains a CRLF, the attacker can insert any arbitrary header into the generated message. For example, if the email parameter is

There are several things that can be improved in your code, I will point out some of them here.
