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.

	DIRECTORY = "PUT DIRECTORY HERE"
	PICTURE_EXTENSIONS = %w{ jpg png }
	BORDER_SIZE = "3x3"
	BORDER_COLOR = "black"
