Do you really think our life applications and oss will be open source at the end for everything?

 Yes, the given statement is true because the life applications like various networking application and computer and television shows are basically operated and monitored by various OSS  (operational support system).

The open source basically refers to the system which is open for all so that everyone can easily contribute. The operational support system handle all the applications based on our daily life. By proper analyzing the operational system so that it provide efficient output and various resources.

Therefore, various life application and operational system are open source.  

Explanation:

The following Python program has a function called addDigits which takes a number as a parameter and returns the sum of the digits. Then the program creates a loop that keeps creating random numbers between 222 and 1000 and divides it by the value returned from the function addDigits. If the remainder is 0 is prints out a statement and breaks the loop, ending the program. The picture below shows the output of the program.

import random

def addDigits(num):

   sum = 0

   for x in str(num):

       sum += int(x)

   return sum

sum = addDigits(random.randint(222, 1000))

while True:

   myRandomNum = random.randint(2, 99)

   if (sum % myRandomNum) == 0:

       print("No remainder between: " + str(sum) + " and " + str(myRandomNum))

       break
