This is a description of a scheme I've used a few times for representing time series data on a fairly small scale. In a nutshell, it uses a single table to house multiple data series on multiple scales and is designed to make it easy to display those series.

Sample Data:

series	timescale	timestamp	value
active-users	weekly	2016-03-05	487
active-users	daily	2016-03-05	75
active-users	daily	2016-03-06	43

What's the point?

Stop fumbling for your phone every time you need to log in to a site with multi-factor authentication. Just run mfa token <profile> | pbcopy and paste the verification code.

(You do need to be able to grab the TOTP key for the site you're logging into, which is usually available somewhere near the QR code when setting up MFA).

Setup:

Install oathtool for your platform.

	Flattens a 'JSON' object (really, a simple potentially nested object
	composed of dicts, lists, and scalars) into a list of key-value pairs.

	Example usage (from http://json.org/example.html):

	> import json
	> flatten_json(json.loads(SAMPLE_JSON))

	[(u'glossary.GlossDiv.GlossList.GlossEntry.GlossDef.GlossSeeAlso.0', u'GML'),
