I could not make my code any better so I decided that I new approach needed to be found… Boom Eratosthenes came to the rescue. I found those two great web sites: Sieve Of Eratosthenes explained and Sieve Of Eratosthenes code. In the second link I found a bit of code that run 10^7 in…

Added some Multi Threading to my code to get full advantage of the dual core on my laptop: import threading import time import inspect import sqlite3 import math class Thread(threading.Thread): def __init__(self, t, *args): threading.Thread.__init__(self, target=t, args=args) self.start() # global variables count = 0 lock = threading.Lock() primeList = [] dbname=’/home/roberto/primelist.db’ table_name = ‘primes’ #…

Finally got some code working with saving the Primes on a DB. I started by saving as I find the prime and realised that the constant IO activity was slowing the all process down. Next step was multi treading: this is still not 100%. Here is the code so far: # Python program to calculate…

If my calculations are right the best way to find a BIG prime number is to iterate through all the prime numbers before it, why? Because the quickest way to check a prime is to see if it is divisible by all the previous primes, I am not going to waste any processing power on…
