The Moon is a Harsh Mistress

Robert A. Heinlein · 1966

Recommended by 2 people on the record.

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

Paul Graham liked it
AI was in the air in the mid 1980s, but there were two things especially that made me want to work on it: a novel by Heinlein called The Moon is a Harsh Mistress

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.
