The bar next to each date shows how long ago it was said: 7d is days, 4yr is years.

I guess you can’t go wrong with Charles Petzold. This book is excellent and highly recommended to anyone interested in computing. Must read for computer science students and software developers.

That little bar

It says how long ago something was said, so you can tell last month from 2014 without doing the arithmetic. Full and green is recent; it drains and cools as the date gets older, and empties completely at about 6 years.

A striped bar means the date itself is an estimate — the source did not carry an exact one. An entry with no date at all gets no bar.
