# Description: Simple demo to showcase Redis PubSub with EventMachine
#
# Update 7 Oct 2010:
# - This example does *not* appear to work with Chrome >=6.0. Apparently,
#   the WebSocket protocol implementation in the cramp gem does not work
#   well with Chrome's (newer) WebSocket implementation.
#
# Requirements:
# - rubygems: eventmachine, thin, cramp, sinatra, yajl-ruby

# ...where 'carefully' means that it does not overwrite
# differing files if they already exist and will not delete
# the original file if copying fails for some reason.

Opening and closing an SSH tunnel in a shell script the smart way

I recently had the following problem:

• From an unattended shell script (called by Jenkins), run a command-line tool that accesses the MySQL database on another host.
• That tool doesn't know that the database is on another host, plus the MySQL port on that host is firewalled and not accessible from other machines.

We didn't want to open the MySQL port to the network, but it's possible to SSH from the Jenkins machine to the MySQL machine. So, basically you would do something like

ssh -L 3306:localhost:3306 remotehost

// Just a little indirection to render a template using handlebars.
// This simple indirection allows much flexibility later one, 
// when using pre-compiling or other templating engine are needed.
Handlebars.templates = Handlebars.templates || {};  
function render(templateName,data){
	var tmpl = Handlebars.templates[templateName];
	if (!tmpl){
		tmpl = Handlebars.compile($("#" + templateName).html());
		Handlebars.templates[templateName] = tmpl;
	}
