If the key is perfectly random, the plaintext won't be retrievable from the ciphertext, since for any candidate plaintext that you could construct, there would be a corresponding and equally-likely key paired with it. Trial and error can't decrypt a message encrypted via random one time pad.
As for the temperature, the Fahrenheit scale is used on SanDisk's product page for the new card. Presumably, that's because Sandisk is an American company, and that page is marketing to a non-scientific audience. In the U.S., that means Fahrenheit would be used.
This is analogous to the use of scientific instruments in astronomy. Everything can be done by hand (technically), but tools make things quicker and easier. They act as force multipliers to make more things practical to do in a shorter amount of time. For astronomy, that means that the astronomer doesn't need to be a million times closer to the thing they're observing in order to see it clearly. For computer science, it means that I don't need to evaluate a billion algorithmic steps by hand.
I don't expect respect from people that don't know me, but for something to be called a "dick move", it actually has to be an action. But go ahead and keep making the assumption that what I say on the Internet maps in a straightforward way to my actions in life. Seems to be par for the course.
Or that the company that funded the video's production wants some assurance that a subscriber won't just tee a rental into a capture program and distribute it without charge to the public.
That's OK. Some clever person will have already figured it out for me. I don't know if they strip HDCP-protection from video and capture the stream, read it out of memory while decoding, decrypt DVR video files or what, but I've no video that I've ever looked for was actually protected by restrictive streaming requirements.
If the executives of a production company feel assurance that their stream can't be ripped in one way or another, then they're living in a fool's paradise.
A cell phone is a flexible device. I don't see a problem with enabling its use in whatever way we can, when it comes to helping someone in an emergency situation.
Lose your distaste.
I'm sure that there are things in the world that you find distasteful as well, and it would be just as effective if an anonymous internet poster said to"lose your distaste" for those things. It may happen through long exposure and desensitization, but it ain't gonna be purely by your say-so.
Photography isn't a crime. Neither is staring intensely at someone and refusing to stop if they're clearly uncomfortable or ask you to. That doesn't mean that it's not a dick move.
because you don't have a legal leg to stand on
Why would that be the first thing that comes to mind? I'm not planning on suing someone for recording me. That would be pointless. Just because I have to put up with something to take part in society doesn't mean that I have to like it (or that I wouldn't appreciate places that share my viewpoint on the matter).
Whoever selected wifi is negligent, but that doesn't fully absolve the deauthenticator of responsibility.
