Picking the right architecture = Picking the right battles + Managing trade-offs

User cases (description of sequences of events that, taken together, lead to a system doing something useful)
- Who is going to use it?
- How are they going to use it?

Probabilistic Data Structures for Web Analytics and Data Mining : A great overview of the space of probabilistic data structures and how they are used in approximation algorithm implementation.
Models and Issues in Data Stream Systems
Philippe Flajolet’s contribution to streaming algorithms : A presentation by Jérémie Lumbroso that visits some of the hostorical perspectives and how it all began with Flajolet
Approximate Frequency Counts over Data Streams by Gurmeet Singh Manku & Rajeev Motwani : One of the early papers on the subject.

	To install virtualenv via pip
	$ pip3 install virtualenv

	Note that virtualenv installs to the python3 directory. For me it's:
	$ /usr/local/share/python3/virtualenv

	Create a virtualenvs directory to store all virtual environments
	$ mkdir somewhere/virtualenvs

	Make a new virtual environment with no packages
