Somebody at MIT had bought a device the size of a calculator that, for a subscription fee, got weather info via radio. Of course they put it on the MIT network, and so of course I scraped it over at Symbolics.
That turned into the "weather hack", which displayed temperature, wind speed, etc. in the wholine of the lispm screen.
And then I wrote the world's silliest expert system in Joshua to *predict* weather (Cambridge only, 15 mins into the future only). It used historical weather data that I'd stored in a Statice database (also on lispm). So it was an example of hooking an expert system up to a database, using some math code (least squares fits to temperature/barometric pressure over time, for example), and logical reasoning all in one application.
