comment What can be done to prevent disruption of hardware in the event of a powerful solar flare?
@ShaneDiDona: depends on "big enough". Conceptually, a solar flare could simply terminally irradiate any living organism on an hemisphere, leaving the other one intact, except for the severe disruption in ecosystems. This has been proposed as a possible mechanism for some past global extinction events, with no definitive proof. A much bigger flare, really the Sun going nova, could wrap the Earth in very hot matter ejected from the Sun, effectively cooking everybody -- it is unclear whether the Sun can actually do that before reaching its old age, in about 4 or 5 billions of years.

comment What is a good practical (and sane) way to manage all your passwords for online sites?
The main things it buys me is that most of my passwords really fit in my brain and are thus usable even on machines where KeePass is not installed. I do not trust many machines and I certainly won't enter my password on a shared machine anywhere, but there are a couple of machines that I trust and yet do not manage directly.
