Comment Re:Yep, Pacific Rim was bad physics (Score 1) 211

An excellent fan theory that covers all of Superman's abilities with a single physics-defying concept is that he can alter the kinetic energy of himself or anything that touches him, and can extend that effect around fairly solid objects.

It's still silly, but at least it's only *one* bit of silly to have to overlook.

Well, that and the yellow Sun thing, and how shards of his home planet seem to have inexplicably crossed the void at FTL speeds *and* magically found their way to Earth. And nobody ever mentions the likelihood of Kryptonite dust contaminating the pod he arrived in, and all those data crystals.

Submission + - Earth may have kept its own water rather than getting it from asteroids (sciencemag.org)

sciencehabit writes: Carl Sagan famously dubbed Earth the “pale blue dot” for our planet’s abundant water. But where this water came from—and when it arrived—has been a longstanding debate. Many scientists argue that Earth formed as a dry planet, and gained its water millions of years later through the impact of water-bearing asteroids or comets. But now, scientists say that Earth may have had water from the start, inheriting it directly from the swirling nebula that gave birth to the solar system. If true, the results suggest that water-rich planets may abound in the universe.

The problem is implementation - once a community gets past a certain size, you have enough people that the marginal nutcases can band together and be a signficant force.

Because most people don't want to spend half their time fighting to maintain a sane community, they just want to participate in the community.

It's not just online forums, I've run into this with fan volunteer organizations and condo associations - there's always someone with more time than you who wants to enforce their overly restrictive moral code on everyone else.

Usually one tiny little semi-reasonable step at a time.

Err... isn't it standard procedure to extract and physically clone the HDD prior to examination, then attempt to crack encryption via rainbow tables?

If you've used a sufficiently long passphrase and sufficiently well written encryption software, they just throw you in jail (assuming we're talking about law enforcement) until you give up the keys.

It's much easier to just use a standard image and use remote access tools to work on a virtual computer that's not within the jurisdiciton/reach of the people you're worried about.

>My favorite example was "Gravity" where orbital dynamics where simply ignored wholesale, mainly because what would take weeks/months/years to develop in reality, needed to happen on much shorter time frames for the sake of the story. If you liked the movie, I'll bet you didn't notice this the first time you watched it.

I gotta tell you, my grasp of orbital mechanics is at Kerbal levels, but that was enough that it ruined major portions of Gravity for me.

It would have been better if the movie (like Interstellar) hadn't been promoted as scientifically accurate when there was obviously no real intention to make it so.

Your previous comment is the same as this one. SHA-2 has nothing to do with it - you could simply encrypt your altered photo. If you wanted to do it the (physically) hard way (assuming you're talking about a camera with internal encryption hardware), you could wire something up to the CCD inputs so the camera doesn't realize it's being fed a pre-made image instead of a view of the real world.
