New MacBook Pro still going on first charge. Hefty downslope (overnight) apparently due to throwing up a modal dialog when a scheduled backup failed. Back to (more) normal now. Screen hasn’t been lit, so this is not quite real-life use. …still going. Might make the 24 hours at this rate. Screen hasn’t been lit a lot of the time, but machine has been “on”.

Humans are very bad at understanding exponential growth (eg: virus spread in populations). So here's an illustration I use in talks.

Here's Wembley Stadium. The watering system develops a fault: in minute 1 one drop of water is released; minute 2, two drops, min 3 eight drops 1/ Now, a drop of water has a volume of 0.07 cc, or 0.000007 cubic metres. Wembley Stadium has a volume of 1.1 MILLION cubic metres. The watering system doubles the number of drops output every minute.

How many hours before Wembley overflows? Or is it minutes? Have a guess. 2/

As you surely know, ZTE broke US sanctions on selling telecoms kit to Iran during the Obama presidency. It said sorry. #huawei
