### AI overview

This video explains why zero-based indexing became common. It discusses efficient use of numeric values and the simpler memory-address formula for arrays, while noting that MATLAB, Lua, and Julia use one-based indexing.

### AI overview

A tutorial and critique of accessing the RealityMining smartphone dataset with Python. It explains the dataset's communication, cell-tower, survey, and friendship data; the access process; the proprietary Matlab file format; and difficulties loading and inspecting the data with SciPy and NumPy.

### Source excerpt

This post is intended to be a tutorial on how to access the RealityMining dataset using Python (because who likes Matlab?), and a rant on how annoying the process was to figure out. RealityMining is a dataset of smart-phone data logs from a group of about one hundred MIT students over the course of a year. The data includes communication and cell tower data, the latter being recorded every time a signal changes from one tower to the next.
