jmhobbs / brute_force_gift_exchange.py
Last active January 1, 2016 11:59
Problem: There are six cousins, three sets of siblings. They are drawing for a gift exchange, and none of them can get their sibling. How many combinations are possible. Math is hard, so I wrote a brute force, which I think is correct. This could be more generic. The nested loops are gross.
siblings = {1: 2, 2: 1, 3: 4, 4: 3, 5: 6, 6: 5}
cousins = set(siblings.keys())
# Start by getting all the possible pairings for each person.
possible_pairings = {1: set(), 2: set(), 3: set(), 4: set(), 5: set(), 6: set()}
for i in cousins:
for j in cousins - set((i, siblings[i])):
possible_pairings[i].add(j)
combinations = []

jmhobbs / coinbase_break_even_calculator.py
Created December 18, 2013 19:34
I wanted to know when I would break even (including fees) on some bitcoins I bought on coinbase. So I built a brute force calculator.
# -*- coding: utf-8 -*-
BANK_FEE = 0.15
COINBASE_PCT = 0.01
def calculate_sale_profit(coins, price, purchase_cost):
value = round(coins * price, 2)
fee = BANK_FEE + round(value * COINBASE_PCT)
return (value - fee) - purchase_cost

Example of consistently selecting a default avatar from a set of available.
<?php
// This is how many different "random" avatars you have.

// Normalize the email address so user input differences doesn't change the avatar.
// This is technically against RFC 2821, but in practice it is ok.
