In order to sample continuous stream of data (numbers). We need to pick up number whos probability of choosing is 1/ (n+1).
#sl is a sample list of numbers which is contiguously getting updated.
import random
def simple_sample(sl):
for x,y in enumerate(sl,1):
if random.random() < 1.0 / x:
sample_data = y
return sample_data

This is the python program for the scale.cpp program.
#Run will execute the run function on scale.cpp
from ctypes import cdll
lib = cdll.LoadLibrary('./libscale.so')
class Foo(object):

self.obj = lib.Foo_new()

The Scale program uses the Boost::ASIO libraries in order to execute the functions in async fashion. It also uses mutiple threads to have io.services run in each of them. I have Interfacing the C++ code with C wrapper .
#include <boost/asio.hpp>
#include <boost/thread.hpp>
#include <iostream>

Just goofing around Boost ASIO library . The following is the first attempt to mess with it.
// You also need to link pthread and boost_system in order to run it. The following will be the command , if you are too lazy to
// type
// $ g++ sample_asio.cpp -o asio -lpthread -lboost_system
//
#include <boost/asio.hpp>
#include <iostream>

rahul8590 / lettercount.py
Created February 27, 2013 13:50
Have the function LetterCountI(str) take the str parameter being passed and return the first word with the greatest number of repeated letters. For example: "Today, is the greatest day ever!" should return greatest because it has 2 e's (and 2 t's) and it comes before ever which also has 2 e's. If there are no words with repeating letters return …
def LetterCountI(str):
l = []
index = 0
for k,i in enumerate(str.split(' ')):
d = {}
for j,c in enumerate(i):
d[c] = d.get(c,0) + 1
d = {key: value for key, value in d.items() if value != 1}
if (not l):

If you want a dictonary consisting of repeating characters only for a given string in python.
# To get a dictionary of repeated characters in a given string
some_dict = {}
for i,c in enumerate("testing"):
some_dict[c] = some_dict.get(c,0) + 1
some_dict = {key: value for key, value in some_dict.items() if value != 1}
