Worried about weak SSL/TLS versions when doing HTTPS requests in Python? All current releases of Python (<= 3.3) do *not* support the latest TLS version 1.2. This is a TLS 1.2 adapter for urllib2/ httplib. Requires a fork of PyOpenSSL found here: https://github.com/enernoc/pyopenssl

	Simple urllib example to demonstrate how to use the `tls12_http` module.

On a slow connection, you might want the send timeout to be different from receive timeout

	import logging
	import socket, ssl

	host = 'www.google.com'
	use_ssl = False
	port = 443 if use_ssl else 80
	ca_certs = None # or path/to/ca_file.pem

	sock = socket.socket(Socket.AF_INET, Socket.SOCK_STREAM)

Script to load EnerNOC Open data (see http://open.enernoc.com/data) into a relational database. Note that this resulted in a ~500 MB sqlite file for all 100 sites in the 2012 dataset. Once the data is loaded, you can make standard relational queries over the data such as: select r.* from readings r join sites s on r.site_id = s.site_id where s.i…
