import System.Random
import Control.Monad
import Control.Arrow
data Throw = Rock | Paper | Scissors

I am writing a program for learning purposes that takes an input of a file structured similarly to:
13,22,13,14,31,22, 3, 1,12,10
11, 4,23, 7, 5, 1, 9,33,11,10
40,19,17,23, 2,43,35,21, 4,34
30,25,16,12,11, 9,87,45, 3, 1
1,2,3,4,5,6,7,8,9,10
Which will then read the values from the file, figure out and print the larg... |

You have an array list of numbers from 1 to 100, the problem is that
one number is missing. How would you find that number?
This is a mock of the question. The code seems to work.
Could you give me some feedback?
private int count;
public void find() {

I am working on legacy code, specifically a sort of BoundedBlockingQueue (mainly used as a pipe between different threads). As it is heavily used in the system and the current implementation features fully synchronized methods and a wait/notify mechanism, I attempted to rewrite it, using the java 5 concurrency utilitie... |
I created small module to help me create rich sendgrid html emails using the mako templating engine. Any feedback on the design would be appreciated:

class MakoMessage(Message):
