Comment Suggested new name (Score 1) 426

They could improve its reputation by changing its name from 'Microsoft Internet Explorer' to 'Blackwater Internet Explorer'.

The original owners of 'Blackwater' are also frantically doing name-scrubs, so the name is currently unoccupied. (Blackwater --> Xe (2009-2011) --> Academi (2011-2014 )--> Constellis (2014-whenever people catch on to the new name).)

Comment Re:Where is the data? (Score 1) 49

There are two main imaging techniques that work in moderate-energy gamma-rays: Coded Aperture which use a shadow mask; and Compton Imaging.

According to this article the camera uses Compton Imaging. In this technique you look at gamma rays that scatter off of one detector and into another. Each detector tells you where the interaction occurred and how much energy was deposited. From this information, you can derive for each gamma ray that it came from somewhere on a hollow cone (with its tip at the first interaction point.) If you detect many gamma rays you can look at where the cones intersect, and that's where the gammas are coming from.

Comment Rollerons (Score 1) 33

Rollerons, such as are used on the Sidewinder missile, are a relatively simple way to limit the spin on a rocket.

Simple wind-spun gyros torque against the fins if the rocket spins, making them pivot to counter the spin.

Could be cheaper and/or easier than precision machining.

Comment Emergency cell tower (Score 5, Interesting) 90

How often have you heard of people who are lost in the woods/at sea, and who could have called for help if they had cell phone connectivity?

They could fly one of these as part of a search. Even if the owner isn't actively using the phone, the drone could detect the electronic serial number of each phone in its coverage area and match it against the lost person's phone.
