I enjoyed your talk. On the kids-and-working-from-home front : Make sure your office is sound-proof. Working at the kitchen table or anywhere you can hear a screaming child is not a good idea. I’ve moved my office setup out to the garden shed – it’s large, comfortable (heated) and has electricity and broadband (via a high-gain antenna). I got seriously into office-shed conversions (just window-shopping mind you) a while back.
