I used this trigger to notify table changes via NOTIFY (migrating off RethinkDB)
CREATE OR REPLACE FUNCTION notify_trigger() RETURNS trigger AS $$
DECLARE
channel_name varchar DEFAULT (TG_TABLE_NAME || '_changes');
BEGIN
IF TG_OP = 'INSERT' THEN
PERFORM pg_notify(channel_name, '{"id": "' || NEW.id || '"}');
RETURN NEW;
END IF;
IF TG_OP = 'DELETE' THEN
PERFORM pg_notify(channel_name, '{"id": "' || OLD.id || '"}');

Created March 18, 2014 16:43
This is a simple example of how to use STS.getFederationToken and its result to perform actions with the new credentials, in this case S3.putObject
var aws = require('aws-sdk')
aws.config.update({accessKeyId: nconf.get('AWS_KEY'),
secretAccessKey: nconf.get('AWS_SECRET')});
var STS = new aws.STS({apiVersion: '2011-06-15'});
var tempCred = STS.getFederationToken(
{'Name': token, 'Policy': JSON.stringify(policy), 'DurationSeconds': 90000},
function (err, data) {

TLS certificate inspection example (using nodejs)
###
#Step 1 - Generate server certificates etc... (most of this code is horribly ripped off from nodejs docs currently -> http://nodejs.org/docs/latest/api/tls.html)

#Assuming your starting from a clean directory
mkdir server
cd server
#generate private key
