I guess Activity Monitor doesn't show a prediction, but it does have a line graph of the percentage of remaining charge as a function of time over the past 12 hours. Not sure if that got removed in the new update.
A basic lens is pretty cheap; the cost goes up when you start adding various coatings or have to do special optics (extreme astigmatism, etc.). In fact, the frame ends up being the costliest part of my glasses, because I want ones that look good on me. I find it curious these adjustable glasses don't correct for astigmatism, though I suppose it's because you'd double the price if you had two cylindrical adjustable lenses instead of a spherical one in there.
Does anyone have a link to the actual patent application? The summary on the linked blog pretty much gives no details about the specifics of the patent (i.e., pretty much any design for a holographic display would have the components listed in the summary of the patent given by the blog) The big elephants in the room are: (1) how do you build a spatial light modulator that has micron-size pixels and yet be big enough to comfortably view a big image, and (2) how do you compute in real time what values those pixels need to be? A holographic display would need one or two orders of magnitude higher pixel density than Apple's "Retina Displays". The summary unfortunately sounds like the equivalent of "we present a patent for making a horse-drawn carriage, wherein you have a horse and it's attached to a carriage, which may be made of metal or wood or some other material, and wow look at the equation that gives you the shape of one of the pieces of the carriage!"
Sure, technology made this fraud a lot easier to commit, but technology isn't an intrinsic part of this ploy; he simply used computer algorithms to implement a lightning-fast pump-and-dump scheme.
Basically, what he did was the equivalent of putting out fake advertisements in a newspaper saying that he'd buy a lot of shares of a certain stock at elevated prices. Traders, seeing these ads, get the feeling that this stock is now worth a lot more than what it is trading at, so they start buying this stock at higher and higher prices. This allows him to eventually sell at high prices the shares he had already owned, making a profit. Meanwhile, when these other traders try to answer these ads, they get no answer and are thus left with a ton of overvalued stock.
Pump-and-dump, insider trading, etc. can all screw up the value of stocks, and they need to be prevented for the market to operate "correctly"; that's why there's laws making these schemes illegal. And while laws don't prevent these crimes, they can certainly help in reducing them.
Frankly, I am still confused as to why it's not (more simply) "circular polarisation" that has been known about since the early days of radio.
Since you linked to Wikipedia, I'm going to assume that Wikipedia didn't do a very good job at explaining the difference. While OAM and circular polarisation both describe some sort of spinning, they correspond to different phenomena. As you may know, electromagnetic waves are oscillations of the electric (and magnetic) field, with the field at each spatial position varying over time. You may also recall from your high school physics class that the electric field at any position is a vector quantity --- it has both a strength and a direction. The polarisation of a electromagnetic field is a description of the direction that the electric field points, and circular polarisation can be roughly seen as the electric field direction rotating as you travel in the direction of propagation. What OAM is describing is the phase relationship between the oscillations of the field at different positions (whether the oscillation at one point is lagged or ahead compared to a different point); it can be roughly thought of as a spinning motion in the transfer of energy inside an electromagnetic field.
For a rather inaccurate, but perhaps intuitive, analogy, try imagining a giant stream of asteroids coming your way in outer space. If the rocks are following a spiral trajectory as they come at you, then this corresponds to the rocks having "orbital angular momentum". If the rocks are themselves spinning, then this corresponds the rocks being "circularly polarised".
I have experimented with the open source jbig2enc library available at http://github.com/agl/jbig2enc, which has a encoding parameter called the “threshold”, described like this:
“sets the fraction of pixels which have to match in order for two symbols to be classed the same. This isn't strictly true, as there are other tests as well, but increasing this will generally increase the number of symbol classes”
The included command tool accepts values for this parameter between 0.4 and 0.9, with 0.85 as the default.
I have found replaced digits in single-page numerical tables encoded with this parameter set as high as 0.82. As with the other examples you have found, the errors are not in any ways obvious to the eye which is, of course, the real problem.
Since JBIG2 has been supported in PDF since 2001, it would be surprising if only Xerox have fallen into this trap.
Yeah they serve all right.. I'm guessing it's not too terribly dangerous to fly about in an armored helicopter shooting at a bunch of asiatic hillbillies with AK-47s.
With AK-47s, and heavy machine guns, and RPG launchers, and portable surface-to-air missiles and such. Oh, and there's always the risks of bad weather and mechanical failure inherent to helicopter flight. Helicopters are dangerous, period, and the Apaches are far from invulnerable. A number have been lost in Afghanistan and Iraq, and some crews have died.
In general, when a piece of military hardware is heavily protected, it also faces powerful threats that make that protection necessary. Otherwise it'd just be carrying extra dead weight that would better be replaced with useful equipment. The military isn't in the business of building invulnerable weapons or letting soldiers fight in "god mode".
And don't you think their opponents wouldn't love to have the coup of bringing down a royal? Just by being in the combat zone, they put themselves at risk.
Because you know if there's ever an imminent threat the members of the Royal Family aren't going to be sat at Buck House with a cuppa tea counting down the seconds...they'll be on their merry way to the other three corners of the globe.
Any member of the Royal Family who did that would rightly be disowned by the rest of the family and the British public, and would probably be looked down upon by much of the rest of the world as well. If the monarch herself did it (and I can't imagine Elizabeth II doing it in a thousand years--she may look like a little granny, but she has far too much backbone for that), she would effectively have abdicated. In the face of such a selfish, craven act, Britain would either find itself a new monarch with more spine, or get rid of the monarchy entirely.
The Royal Family enjoys a lot of privileges, but in the end they exist to serve the British state, as its personification. Their lives are far more controlled and circumscribed than ordinary people.
Just look at the case of Edward VIII to see how Britain might treat a monarch who doesn't take his duty seriously.
