How do I sort a dictionary by value?
..., simplified here as:
from collections import defaultdict
d = defaultdict(int)
for w in text.split():
d[w] += 1
then you can get a list of the words, ordered by frequency of use with sorted(d, key=d.get) - the sort iterates over the dictionary keys, using the number of word occurrences as a s...

@zeekay: I think you might need to change self.items() into iter(self.items()) inside __reduce__. Otherwise, PicklingError exception is raised complaining that fifth argument of the __reduce__ must be an iterator.

String Concatenation using '+' operator
..."there";
string z = "chaps";
string all = string.Concat(x, y, z);
(Gah - intervening edit removed other bits accidentally.)
The benefit of the C# compiler noticing that there are multiple string concatenations here is that you don't end up creating an intermediate string of x + y which then needs...
How to Sort Multi-dimensional Array by Value?
...re them: If the first element is bigger than the second, return a positive integer, if it is smaller, return a negative one. If they are equel, return 0. PHP then sends two other elements to your function and continues to do so, until the array has been sorted. The function here is very short, it mi...
What is the purpose of fork()?

Typical usage of fork in a shell might look something like this:
int child_process_id = fork();
if (child_process_id) {
// Fork returns a valid pid in the parent process. Parent executes this.
// wait for the child process to complete
waitpid(child_process_id, ...); // omitt...
