Comment Re: OT Re:legalism is a crap philosophy. (Score 1) 582

Hi, AC. Yes, I understood what I wrote. Where the exponent in a function is a constant (in this case 2), that function is polynomial. An exponential function has the parameter in the exponent. The energy in a collision is not an exponential function of the speed. Sheesh, Slashdot used to be populated with geeks!

That's because I'm not offering any such calculation. OT means off-topic, right? I just pointed out that, somewhat like "literally", the term "exponentially" is being abused.

As far as calculation goes, the energy of a collision between two objects at a relative 30 mph is exactly 1.5^2 = 2.25 times larger than one between the same two objects at 20 mph, so yes, of course the damage is much larger. Nothing I wrote should be seen as favouring high speeds, rather just exact use of language.

And then there's the whole class of ideographic allusions, somewhat like puns but with no analogue in an alphabetic written language. The character chosen to match to a particular word can carry hidden meaning within it. See for instance Graphic pejoratives in written Chinese. Although many of those racial and ethnic slurs have been eliminated, it would be really hard (and counter-productive, and wrong) to try to remove that aspect of the written language.

My dear fellow, I didn't go that far off the beaten track! On clicking "Get ReadCube", I got a page that said (I kid you not) "Aw, shucks, ReadCube is not available for your platform". Aw, shucks!?? WTF, I didn't come here to be talked to in that tone of cyber-voice. As I said, BZZZZT!

Comment Highlight quotes from the judgment (Score 1) 284

I recommend everyone to read J. Furman's judgment: it's crystal clear, and a pleasure to understand.

The argument establishes that what Baidu is engaged in is speech, not advertising or anything, I think these two quotes (or quotes of quotes) sum everything up beautifully:

'Since all speech inherently involves choices of what to say and what to leave unsaid,'" the Court explained, "one important manifestation of the principle of free speech is that one who chooses to speak may also decide 'what not to say.'"

As the Supreme Court has explained, "[t]he First Amendment does not guarantee that . . . concepts virtually sacred to our Nation as a whole . . . will go unquestioned in the marketplace of ideas."

what movie did you get that from?

You get to my age, some things in movies are almost as real as what really happened :)

However, this discussion on PPRuNe suggests that I didn't make it up. Several professional pilots are on there saying that it's their normal practice. Before anyone points it out, I can see that the thread is ten years old, and it may very well be that modern CVRs aren't using 30 minute magnetic tape loops.

Comment Pilot resistance (Score 1) 461

Nobody seems to have mentioned that *pilots* would/might resist the streaming of flight data to the ground. As I understand it, there's a button in the cockpit which erases the flight deck voice recordings, and that button is one of the first things that the captain presses when the plane has landed.

What's said on the flight deck, stays on the flight deck!

Comment Dumping BitCoin (Score 1) 276

Yes, as far as I can see, if you "corner" a market in BitCoin then you can control its price. A BitCoin, like a dollar or a diamond, is worth exactly what someone will pay you for it.

There was a similar flurry about virtual goods in Second Life, I vaguely recall.
Back on topic, is anyone alleging that the "real" Satoshi Nakamoto has cornered the market? If there is a real concern that the bitcoin architect could bring the edifice crashing down, I'd say that that was a good reason to stay well outside the said edifice.

> amassed a huge amount of money doing so

Well, it's more like that the early miners of bitcoin, including its inventor, *made* something that you (and several others) now want. He didn't amass money, he made something difficult (read: impossible) to forge, that now has a real-world value. Think of it like artwork.

I don't understand why anyone wants to know who Satoshi 'bitcoin' Nakamoto is. How will you be better off if you know?
