The true fathers of computing via Guardian Technology by John Naughton
George Dyson’s new book challenges computing’s creation myth by highlighting the key role played by John von Neumann

Air France's 1947 sleeper service via Boing Boing by Cory Doctorow
There's loads to love about this 1947 ad for Air France's sleeper service – just look at that cutaway diagram! – but the chart-topping eye-grabber is that awesome sleeper-service bed. Man, if Air France was still flying planes with that interior, I'd never fly anything else.
