After Scalabrini's victory in the #ConCourt the astroturfers could hardly have left it alone. Problem is, it's in a city where they have no support. What happens when you have pogrom & nobody comes? That's what's happening right now. Far more media & human rights observers than would-be vigilantes!

A B&W photo of a person standing next to a stack of printed paper as high as the top of their head. This is Margaret Hamilton, at work as a Software Engineer and the leader of a team of extremely specialised programmers who worked for NASA. The photo was taken in 1969, and it shows a physical form if her work since she joined the Apollo project in 1965 (she joined at the age of 29 by my calculation). My interpretation of the expression on her face is a mix of pride and mild amusement.  She has glasses, long, straight hair, and neat office attire. Margaret Hamilton has her hands placed gently on the stack of printouts to keep it all balanced upright. The pages appear to be arranged in bundles, ranging from 8-10 centimetres thick, to 20cm thick or more. The resulting stack of printouts is physically impressive for being an unusual feat, and it represents something even more impressive: it's the printed form of the source-code she and the team she led wrote for the NASA Apollo project. Their software ran on the Apollo Guidance Computer that was that on board each Apollo command module and Apollo Lunar Module. The Apollo Guidance Computer onboard the Eagle was an essential flight instrument for Neil Armstrong when he piloted the craft to land on the surface of the moon.
