Euler Problem #7 - 10001st prime number (much (20x!) faster - now break when primes > sqrt prime candidate)
primes = [2]
count = 1
prime_candidate = 2
start = Time.now()
until (count == 10001) do
prime_candidate +=1
while (true) do
psqrt = Math.sqrt(prime_candidate)
unless primes.
find do |prime|

Ruby solution for http://qandwhat.apps.runkite.com/i-failed-a-twitter-interview/. A bit more verbose but perhaps slightly more efficient solution than others? Nope, just more verbose.
