20 megatons is not a very powerful explosion. Didn't the Russians explode a 57 megaton thermonuclear device back in 1961? Apart from nuclear fallout, nothing particularly catastrophic had happened. Since most of our planet's surface is not populated, the odds of an asteroid hitting a populated area is not very high.

So, our children may witness a 20 megaton explosion in some remote location. Not a big deal.

I noticed a severe slowdown after upgrading from 1.5 to 2.0, but only on one specific machine (AthlonXP 2000+, 1GB RAM). This behaviour puzzles me to this day, as I've been unable to find the source of the problem. So I'm not surprised that some users experience performance issues while others do not.

Another thing worth mentioning is that an e-mail client should not need a state-of-the-art machine to work smoothly. I used to use Thunderbird 2 on a 6 years old Pentium-M laptop (without any performance problems), and I would expect a new version of the same software to run just as well as the previous one. If it doesn't, it's broken and needs fixing.

Projecting an image of the Sun to a screen is way more convenient - many people may watch at the same time.

Instead of
$ history | grep grep | wc -l

you may want to try
$ history | grep -c grep

Just sayin'.

They're in it for themselves, only themselves, and they will generally fuck you until you're blind if it means making an extra dime.

Just a side note: isn't that what capitalism is all about?
