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.

Once you hit Kardeshev-III, it's a long hard slog to M31, and that only buys you another doubling.

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.

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.

These are the days of lasers in the jungle.

Lasers in the jungle somewhere.

If it is 53 cm instead of 5 feet, then scaling from the video is off by a factor of (5 feet/53 cm)^3 = 24 and his 4 bbarrels per second becomes 15 thousand barrels per day, assuming he only made that one mistake.

This is not good, but it is closer to the mainstream media than to the Revelation-quoting Alabaman.

There's no reason to believe a brute force attack on AES128 will never succeed.

Also implicated in the assassination was Prawo Jazdy.

The most ecologically sound place to put people is underground. The dead don't reproduce (though, surprisingly, their number increase every day) and they don't use energy, food, or other resources.

That doesn't mean that it's a good way to live.

Much better than that 2 trillion degree quark vichyssoise.

Uncrop.

A fifth of a second is about the time it takes to blink. It's about 12 frames of a 720P HD video signal.
