Apparently the number 20 was assigned earlier, when the larger outer planets were discovered in this system.

As someone else already pointed out, DMZ is an extremely volatile place. This is not the first time when a tree is a source of tension. See the "axe murder incident": http://en.wikipedia.org/wiki/Axe_murder_incident

Simply put, the neutrino emission starts before the emission of light. This article has details: http://library.lanl.gov/cgi-bin/getfile?25-14.pdf

As far as I remember, port to Qt4 is planned for the future. You might want to check the project's roadmap, once the wesite becomes more responsive: http://www.trinitydesktop.org/wiki/bin/view/Developers/RoadMap

Never fear, arXiv delivers: http://arxiv.org/abs/1010.1489

TFA is wrong, the planet was discovered from a ground-based observatory back in 2006: http://arxiv.org/abs/astro-ph/0609335

Open source developers want to experiment, and they implement pseudo-features that most regular users neither want or need. For this reason, the latest versions of major desktop environments (Gnome 3 / KDE 4) are fundamentally broken. Wayland simply follows the same trend.

Thanks for releasing stolen passwords for 62000 email accounts. Spammers must be very happy now.

Confiscate the computer with a self-encrypting HDD. Boot a live CD, image the HDD. Analyse the image.

Or am I missing the point?

If you're using Firefox it's easy to get rid of all history entries from a given domain. Don't know about other browsers out there, but I guess they should have a similar feature.

"Kepler looks at every star in its field of view."

This is not entirely accurate. Kepler observes each star in its FoV, but doesn't send all the time-series data to Earth - just data concerning a selected subset of stars.

This is a problem with science in general. Many scientists tend to make very bold claims, only to make sure the funding of their research will be continued.

It seems that the Kepler team is starting a campaign to ensure the Kepler mission will be extended.

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.
