l0gicpath / problem_2.erl
Created January 31, 2014 13:35
Because my other 5 line Erlang solution was too long.
-module(problem_2).
-export([s/0]).
-define(L, 4000000).
s() -> s(1, 2, 0).
s(P, N, S) when P >= ?L; N >= ?L -> S;
s(P, N, S) -> S1 = case N rem 2 of 0 -> N + S; _ -> S end, s(N, P + N, S1).

Streaming your screen over http using screenshots. Uses 'screencapture' for mac systems, you'll need to find another screen capturing utility to be used from the terminal on your system of choice. An enhanced code over https://gist.github.com/blazeeboy/9151757
#! /usr/bin/env ruby
require 'socket' # needed for creating tcp servers
require 'base64' # we'll use base64 for encoding images and embedding them in the response
require 'cgi' # has a lovely helper method for generating rfc1123 compliant dates for http headers
refresh_rate = 1 # in seconds, interval between each screen capture
server = TCPServer.open 3005 # start our server at port 3005
