The result is here! Our 3 lucky winners are: iScream, tommygunster, TrojakEW.
Congratulations and enjoy H7S! The serial number has been sent to your email.


We used MT19937 pseudo random number generator, and used the Epoch second number on time 2017-12-25 00:00.00 as seed.
The winners are generated from following procedure:
1: a random number between 2 and the number of participants is generated, it is used as the times of shuffling.
2: each participant is assigned with an ID according to their reply in the activity post. Duplicate ones are removed.
3: shuffling is performed by previously decided times, the first 3 IDs in resultant shuffled list are selected as winner.
The shuffling and random generator in C++11 standard library was used. The source code was compiled by GCC 6.3.0.

See blow for source code:

#include <algorithm>
#include <iostream>
#include <random>
#include <vector>

#define ACTION_DATE_EPOCH 1514160000
#define NUM_FETCH 3

int main()
{
std::vector<int> indices = {
2,
3,

};

// create pseudo random number generator
// initialize using the second number since Epoch of this Christmas
std::mt19937 prng;
prng.seed(ACTION_DATE_EPOCH);

// decide how many times to shuffle
// the number must be at least 2, otherwise the result has fixed prefix
std::uniform_int_distribution<int> dist(2, indices.size());
int times_shuffle = dist(prng);
std::cout << "shuffle " << times_shuffle << " times" << std::endl;

// do shuffle for that times
for (int i = 0; i < times_shuffle; i++)
std::shuffle(indices.begin(), indices.end(), prng);

// tell result
for (int i = 0; i < NUM_FETCH; i++)
{
std::cout << indices[i] << std::endl;
}
}


Merry Christmas and Happy New Year!
