Due to having a very unstable connection in China, I wrote a script to alert me when my internet is down. If the internet is down, it will say so every 5 seconds until it is back up. If it is up, it will say this once and then shut up. The log messages are a delta.
#!/usr/bin/env ruby
require 'logger'
class SimpleDaemon
def self.start pid, pidfile, outfile, errfile
unless pid.nil?
raise "Fork failed" if pid == -1
write pid, pidfile if kill pid, pidfile
exit
