Big Data, 2018-19 edition

Minutes for lecture V

----- Plan for the day -----

- Iterables, more iterables and files.
-- follow up on Snakify

Iterables are there to manipulate SETS.
Spreadsheets have ROWS for the same reason.
Example: Katzaros' index: =($B2+$J2)*(4/(2018-$C2+1))
Importance = (4 x # of citations) / # of years elapsed

- Practicum: installing and running Python *locally*
 -- a per-host installation of Python 3 and some editor

-Exercise: estimate the number of cancelations (churn) in Facebook
 -- download the dataset
 -- write own Python code; debug; repeat
 -- create own mini-instance; run; validate
 -- run stat on actual instance
