The British have a way round this:

Alice, in the UK, makes sure all her passwords are too long to remember. So she stores them with Trent, in the USA.

Trent has been told only to reveal Alice's passwords if she has phoned him with her daily dead man's handle.

Plod, also in the UK, asks Alice for her passwords citing RIPA 2000. Alice is held at Plod's luxurious police station for a day, then tells Plod that she hasn't stored them in the UK because they're too long to remember and that Trent has them. Plod calls Trent, who not having received yesterday's dead man's handle, pleads the 5th.

Comment Re:150 db won't just cause physical pain. (Score 1) 193

Not trying to defend the use of these weapons...

Just pointing out that the 150dB figure is at one meter rather than the recipient's position (and obviously the sound falls off according to inverse square law).

The 120dB quoted rock concert figure would be the amplitude at the listener's position.

Comment Re:In film, frame rate = exposure time (Score 1) 607

I'm sorry, but that is just absolutely wrong.

Cinematic motion blur is related to shutter angle, normally 180 degrees, which hasn't changed for decades, except for notable particular stroboscopic effects, the most famous of which is the opening sequence of Saving Private Ryan

The shutter timing was set to 90 or 45 degrees for many of the battle sequences, as opposed to the standard of 180 degree timing. Kamiski clarifies

A normal 180 degree shutter gives an exposure time of 1/48th second.
