test-connection got you down? ping just not cutting it for you? How about using the System.Net.NetworkInformation.Ping.send() method

	# with reference to http://theadminguy.com/2009/04/30/portscan-with-powershell/
	function fastping{
	[CmdletBinding()]
	param(
	[String]$computername = "127.0.0.1",
	[int]$delay = 100
	)

	$ping = new-object System.Net.NetworkInformation.Ping

	#!/bin/sh

	# Converts a mysqldump file into a Sqlite 3 compatible file. It also extracts the MySQL `KEY xxxxx` from the
	# CREATE block and create them in separate commands _after_ all the INSERTs.

	# Awk is choosen because it's fast and portable. You can use gawk, original awk or even the lightning fast mawk.
	# The mysqldump file is traversed only once.

	# Usage: $ ./mysql2sqlite mysqldump-opts db-name \| sqlite3 database.sqlite
	# Example: $ ./mysql2sqlite --no-data -u root -pMySecretPassWord myDbase \| sqlite3 database.sqlite

Last active January 2, 2016 19:39 — forked from phobeo/javascript aspect ratio calculation (with GCD)

Demo: http://jsfiddle.net/sinky/gXBCk/

	/* GCD */
	function gcd (a, b) { return (b == 0) ? a : gcd (b, a%b); } // Source: http://stackoverflow.com/a/1186465

	/* ratio is to get the gcd and divide each component by the gcd, then return a string with the typical colon-separated value */
	function ratio(x,y) {c=gcd(x,y); return ""+(x/c)+":"+(y/c)}

	ratio(1920,1080)
	/* "16:9" */
	ratio(320,240)
	/* "4:3" */
