"Your teeth will get through anything," Mr. Kayll advised. "But it will bloody well hurt."

Speak for yourself, my teeth will barely get through a cheese sandwich at my age.

There's nothing like a good smack to the beitzim to stop a would-be rapist. And there's nothing like biting someone if it's all the leverage you have.

Remember, this is not a video game or a sanctioned fight in a boxing ring. This is your life versus the life of a terrorist or other attacker. Kill or be killed. Learn to fight.

Back in 2002 I was working with image processing, and I came up with a video compression idea: treat the video as a 3D image and apply 3D Fourier transform, then drop the weaker components as done with similar 1D/2D schemes. This would provide a natural balancing between temporal and spatial resolution, depending on the scene. I wasn't much of a programmer back then, but I later realized this would probably be too heavy for practical use. I also learned that the same idea had been put into development around the same time as Ogg Tarkin, but it didn't get very far either.

As a bonus, the Fourier/wavelet format could be decoded in arbitrary resolutions in space or time. This idea is actually used in some music playing libraries, producing 24-bit output from a format intended for 16-bit quality.

eVTOL man-carrying craft (flying taxis and flying cars) are not yet economically viable -- and won't be until we have a whole new generation of batteries with higher energy densities and cycle-lives. At the current cost of operation, these are a solution looking for a problem.

Hell, China can't sell all the EVs it makes so the chances of them selling any of these is....

Congratulations to Blue Origin! This is an accomplishment, and the fact that there are now 2 partially-reusable launch systems available should be great news for companies that want to put payloads into orbit.

New Glenn is a much bigger rocket than Falcon 9, and bigger than even Falcon Heavy.

New Glenn is fueled by Liquid Oxygen and Liquid Methane, so the first stage won't have coking issues like Falcon 9 and Falcon Heavy. We will see whether this gives Blue Origin an advantage in turning-around and re-launching the booster.

And New Glenn has successfully launched payloads into orbit, something Starship has not done so far.
