Comment Re:Which DVD was in the player? (Score 1) 485

How on earth did you figure this? This is bullshit science. You are at least totally ignoring the owners personal taste.

Well, from a frequentist perspective, the probability is either 100 % or 0 %, depending on the disc was indeed HP or not. But the witness didn't know this, nor did he know the personal taste of the driver.

From a Bayesian perspective, it depends on what assumptions we make. If we assume that the probability that a film was selected is proportional to its box office performance then the probability is on the order of 1/1000. Since people are more likely to watch movies that they haven't seen before, the probability of a recent release is much higher than an older one. (This does not apply to people who cannot afford new DVDs or to boring people who could afford to buy new things but don't. Neither of those would own a Tesla.)

Even if we also assume that Tesla owners only watch DVD's of films released in 2011, then the only goes up to 3 %. Still low enough that it would be significant if the witness was right.

The witness says a Harry Potter movie was playing. If he was making this up, then there's a less than one in a thousand chance that the DVD player actually contains a disc with a Harry Potter movie. (The last disc of the series was released on DVD in 2011. A Tesla owner would be much more likely to be watching a more recent release.)

Investigators know which disc was in the player, so they know if the witness is telling the truth.

Indeed, autopilots on boats kill people all the time. (Most common case, the guy falls overboard while taking a pee and the autopilot sails away, leaving him to drown.) Yet I've never heard of anyone arguing that they should be banned (or even that they should only be allowed on boats with indoor plumbing).

What we need is for the world's environmentalists to realize that energy storage and infrastructure projects are more important the solar cells and wind farms themselves.

When an environmentalist engineer says to an environmentalist politician that "This $100 million solar farm will be useless unless we also invest $500 million in energy storage and infrastructure" the response will always be "Why are you bashing solar cells? I'm firing you and replacing you with someone who cares about the environment." rather than "OK, I guess I'll have to find another $500 million in funding".

It would seem they compensate for the tiny rotors with very high rpm. Increadibly noisy, and creates enormous forces on the rotor blades, but theoretically possible. The video states that they need 1 MW of power for lift-off, and that the engine provides 0.2 MW (300 hp), so it would take 0.8 MW worth of batteries. They're probably lithium polymer, like in miniature helicopters.

people who envision draconian laws always do it believing that they'll never become a victim of their own fuckery.

He wouldn't be. According to TFA, there would be an exception for people with "academic affiliations" as well as for the press, and anybody else with an audience.

If your read between the lines it's pretty clear that he's saying that only muslims could go to jail for being rickrolled, and that's OK, because think of the children!

Nope, apparently they do give you the decryption key, once you pay. If word of mouth was that it doesn't help to pay, then a lot less people would pay the ransom.

So this guy is destroying a very lucrative business model for some very evil people. It will probably not end well for him.

By the title of the paper -- A Faster Cutting Plane Method and its Implications for Combinatorial and Convex Optimization -- I would say that they are not trying to provide a truly general optimization algorithm, but one that is specific to combinatorial and convex optimization. Hence, the NFL theorem is not violated.

TFA headline gives the impression that they would be talking about a truly general algorithm, but this is actually a manifestation of the "No Competent Editor" theorem.
