The system function attempts to bring the C system() function to node.js with extended functionality. system() executes a command and fires an event when done that will return the command output. system has 2 events: 'data' - returns the output data of the command 'exit' - returns command exit code dependancies npm install colors Examples of the…

divanvisagie / nth_largest.cpp
Last active December 11, 2015 01:48
This is pretty much the answer( or at least mine ) to the typical CS question : Find the nth element of an array without sorting or creating a new array. I have a very nice version using templates and all the fancies , and then an Arduino version that is float specific.
#include <iostream>
using namespace std;
/* This function uses a trick with templates
to determine the size of the array */
template <class T,size_t size>
size_t arr_size( T(&)[size] ){
return size;

Last active December 11, 2015 03:48
I have noticed a lot of people seem to go to very unnecessary lengths to strip NSlogs (see Insane.mm) , where all thats required is something simple. Rule of Clarity: Clarity is better than cleverness - https://en.wikipedia.org/wiki/Unix_philosophy
/* who would do this ? , its insane */
#ifdef DEBUG
#define DMLog(...) NSLog(@"%s%@", __PRETTY_FUNCTION__, [NSString stringWithFormat:__VA_ARGS__])
#else
#define DMLog(...) do { } while (0)
#endif
