I've written a couple of functions to check if a consumer of the API should be authenticated to use it or not.
Have I done anything blatantly wrong here?

API_CONSUMERS = [{'name': 'localhost',
'host': '12.0.0.1:5000',
'api_key': 'Ahth2ea5Ohngoop5'},

I have a string that must be splitted into an array of strings so using strtok makes perfect sense but before that I want to allocate the array of strings and thus I count how many words in it.
static inline int countWords(char *str)
{
int count = 0;
char *buf = str;
if(isgraph(*buf) > 0)//chec... |
I've planning to create crosswords game for Android platform.
Basically, crossword is a matrix of TextFields (EditTexts) and TextViews. Each crossword might be in american style (first TextView in every question stores question number, and there's no TextView with clue) or swedish (first TextView stores arrow indicati... |
I just learned about Maybe in Haskell, so I decided to try to use it with a binary search.
Here's the function:
binarySearch :: (Ord a, Int b) => [a] -> a -> b -> b -> Maybe b
binarySearch l e beg last
| lookat < e = (binarySearch l e i last)
| lookat > e = (binarySearch l e beg i)
| lookat == e = Just i

I have been coding for some time (3 years I think), and have recently been wondering if my coding pattern is any good. Any kind of feedback is welcome:
EDIT: The thing that concerns me most is that I have read a lot around that getters/setters are bad for OOP. Is this true?

I have three methods that are really similar but do slightly different things. This doesn't feel very DRY to me, but I can't think of a way to reduce the duplication. Here are the methods, I think they're fairly self explanatory:
# Present a date as a string, optionally without a year
# Example output: "December 1, 201... |
I need to write a jQuery plugin that doesn't take an element to work.
Example call:
$.funkyTown();
... not called like this:
$('#foo').funkyTown();
...in other words, I need this plugin to act more like a "utility" plugin (vs. apply itself directly to a matched element(s)).
Here's what I have written so far:

I wrote a small script as an answer for a Stack Overflow question, which referred to counting lines of code and comments (in C and C++ style).
f = File.open("test.txt")
loc = 0
comments = 0
while line = f.gets
if commented ||= line.match(/^\/\*/)
commented = nil if line.match(/\*\/$/)
comments += 1

I am trying to solve the "Meeting Point" problem from interviewstreet.com:
There is an infinite integer grid at which N people have their houses on. They decide to unite at a common meeting place, which is someone's house.
From any given cell, all 8 adjacent cells are reachable in 1 unit of time.
eg: (x,y) can b... |
