@garius: It is election season. The world is busy and rubbish. But it is also Christmas. So take a breather and let me tell you a story about London, trains, love and loss, and how small acts of kindness matter. I'm going to tell you about the voice at Embankment Tube station.

@trevorsumner: Some people are calling the 737MAX tragedies a #software failure. Here's my response: It's not a software problem. It was an * Economic problem that the 737 engines used too much fuel, so they decided to install more efficient engines with bigger fans and make the 737MAX.
