Cool demo
(backposting) FedEx tried to deliver something on Monday, but I'd gone out for lunch (and not realised how quickly it was going to arrive from Canada), so today I drove to Chelmsford to their depot, to pick it up. It's a really cool demo to show off some of our technology. It's about barcodes, and digitally signing them. Nice stuff, and I'll be taking it out to Geneva next week.This evening, I popped round to fix Charles' computer. He's the son of some friends of ours, 13 or so, bright, and a nice guy. Having fixed his PC (partially unseated RAM), installed Firefox and AVG anti-virus, his mum wanted to know how he should repay me. I'd given him a cryptography 101, and so I decided that that next time he sees me, he needs to be able to explain the differences between symmetric and asymmetric encryption. I even gave him the requisite wikipedia page. This is a bit geeky, but he'd shown an interest, so... We've also agreed that we're going to buy a cr*ppy old PC, rebuild it, and put Linux on it. Yes, geekery.
Tomorrow is Jo's 3rd birthday, and we wrote the card and wrapped the presents. Oh, the excitement.
