What is the utility of having static functions in a file ? How are they different from having global functions in a file ? static int Square(int i) { return i * i; } vs int Square(int i) { return i * i; } What is the utility of having static functions in a file? You can use these functions to provide shared implementation logic to other functions within the same file. Various helper functions specific to a file are good candidates to be declared file-static. How are they different from having global functions in a file? They are invisible to the linker, allowing other compilation units to

UPDATE: See the answer I've provided below for the solution I eventually got set up on AWS. I'm currently experimenting with methods to implement a global load-balancing layer for my app servers on Digital Ocean and there's a few pieces I've yet to put together. The Goal Offer highly-available service to my users by routing all connections to the closest 'cluster' of servers in SFO, NYC, LON, and eventually Singapore. Additionally, I would eventually like to automate the maintenance of this by writing a daemon that can monitor, scale, and heal any of the servers on the system. Or I'll combine

I need to read some words text by text in python, and I am getting this error. "NameError: global name 'wordList' is not defined. i=0 with fitxer as f: for line in f: for word in line.split(): wordList[i]=word i+1 return wordList You need to define wordList to begin with. And you cannot randomly assign indexes in an empty list. You can easily 'extend' the list with new values. worldList = [] with fitxer as f: for line in f: wordList.extend(line.split()) return wordList wordList is not instantiated as a list or not in scope. If wordList is a global variable, the beginning of your function will

I am new to CodeIgniter. I am using HMVC in CodeIgniter and want to use a module function in many other modules: e.g I have a Locaton_model with function get_locations($param) { return; } How do I use the above function in many other modules? Should I load the model in other module controllers every time I need this function or define the function some where globally? You can easily achieve that by using core controllers: http://ellislab.com/codeigniter/user-guide/general/core_classes.html Instead of beginning your model with: class Some_model extends CI_Model {} You start with: class Some

here is simple cuda code. I am testing the time of accessing global memory. read and right. below is kernel function(test1()). enter code here __global__ void test1(int *direct_map) { int index = 10; int index2; for(int j=0; j<1024; j++) { index2 = direct_map[index]; direct_map[index] = -1; index = index2; } } direct_map is 683*1024 linear matrix and, each pixel has a offset value to access to other pixel. index and index2 is not continued address. this kernel function needs about 600 micro second. But, if i delete the code, direct_map[index] = -1; just takes 27 micro second. I think the code
