A great history of early computer science, from a logician's point of view, is The Universal Computer by Martin Davis. www.amazon.com/Universal-Co...
Martin was himself an important figure in the history of computer science and logic (and a dear friend -- I will always miss him).

Progressive Era - Wikipedia

Unions & the income tax were facets of the progressive movement, which was broadly anti-monopoly. We need a pile of that today. See en.wikipedia.org/wiki/Progres...

Unions, the income tax (1913), the Great Depression all combined. I'd bet the Depression was the death knell.

Anyone who writes β€œGenuine question, …” or β€œJust asking …” or the like and who isn’t a troll is getting blocked anyway. Civilian casualties in the war against trolls are tragic but avoidable as long as you don’t act trollish.

And don’t feed the trolls. Block as soon as they pop up.

A large number of accounts have followed me in the last few days, many with names like gloomy, Snowy, jako, 60% diet soda by weight (really!), nap, Isa, etc. I might follow any actual friends back, but their names and bios give me no clue. I'm sure other people are having the same problem...

Pull the plug and it becomes incapable of doing bad things.

Happy pi day! This is a drawing of a sphere made of little cublets done by my AxiDraw V3A3 pen plotter, using black and grey Pentel Energel 0.7 pens on 18gsm white card stock. Cublets are included or excluded depending on the bits of the binary expansion of pi. #piday #penplotter #axidraw

Robinson Crusoe on Mars is the first movie I went to see by myself, in 1964, when I was 13. (Solo trip on the bus to the theater in a strange part of town, not something that kids do any more!) I still think of it fondly.

And Julie London was married to Bobbie Troup, her Emergency! costar. He was also the composer of β€œRoute 66”, a hit for (separately) Nat King Cole, Chuck Berry and The Rolling Stones. What a family!

You know that Thiel doing what he thought was right and actually doing right are two different things.
