Interesting Things on the Internet: February 25th 2019

• Leeway. An excellent exploration of why we need systems which don't blindly apply a rigid set of rules. (That's the same argument for why most home automation will just annoy us with unexpected edge cases).
• How Austerity, and a Cowardly Ruling Class, Brought About Brexit. "I want my country back too, as it happens. But I'm not kidding myself about who stole it. The Tories sold out the British people and then made the mistake of giving them one real chance to make their feelings known—and, well, when all you have is a hammer, everything looks like David Cameron's face."
• Known Assailants. A well-written account of failed social mobility in the US. Social mobility seems almost dead these days. Given the mess the upper class is currently making of the UK, it's in everyone else's (the upper class will be insulated regardless, and some are likely to profit from it...) interest to be finding ways to bring it back.
• Building the Barbican. Fascinating report into the workers who built the Barbican. Includes such scandalous behaviour as one of the contractor companies engineering strikes to try to get out of (or renegotiate) a contract they'd under-priced in their bids, and stories of the establishment siding with management over the workers despite their valid (and relatively minor) demands.
