Graphing when your Facebook friends are awake

on YouTube ↗28m

" summary

A small tool scrapes Facebook’s undocumented /pull endpoint via browser cookies and inspect‑element to log friends’ presence JSON continuously, then converts logs to CSV output and tries Matplotlib, Bokeh and NVD3 for visualization. The produced timelines let inferred sleep/wake periods be drawn from gaps in activity; the code lands on GitHub and accumulates 17 issues. It works well enough to reveal nightly patterns and feels creepy, and disabling chat presence on Facebook is the practical mitigation.
