kvannotten / check_internet.rb
Last active December 22, 2015 06:48
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

Script that allows you to run some manipulations on images in a threaded way. This script uses celluloid to create actors that manipulate the pictures by resizing them and adding a border.

BORDER_SIZE = "3x3"
BORDER_COLOR = "black"
