Ever seen the lights dim in your house when the AC comes on? That disturbance produces a higher frequency swing than this article is talking about. It may just be a voltage drop, but if you perform a Fourier analysis over the disturbance, you'll see a large phase shift over the transition. Power generators experience huge swings when power lines go down, and demand drops in the megawatt range. Happens all the time. Your fans don't break.
Not quite. You still need the frequency (Hz) to be the same on both sides. This is more like advancing the spark timing in your car's engine. If the spark comes late, your engine produces less power. As you advance the spark, the engine produces more power... at least until it starts backfiring or producing other expensive sounding noises.
For many purposes, unsigned types just delays a problem. "I need to count over 32000 so I'll use an unsigned short"... And then the code breaks when the unexpected happens, and the count exceeds 65000. An extra bit of count range is NOT desirable... If you want bigger counts, use the larger type!
For the most part, math on unsigned integers produces the same result as math on signed integers. Division, being the exception, but if you are dealing with integers, you likely aren't doing a lot of division anyway.
Count down loops are harder with an unsigned variable. "for( x=10; x>= 0; x--)" is an infinite loop!
Bit banging is really the only place the unsigned types are useful.
If you really, really, need unsigned integers for a particular problem, you could always use JNI and program that part in a different language.
Thanks for the info. Pity the theory didn't stand up; I liked the "oh hey, the missing matter has been shining away brightly, running and waving 'Look at me! Look at me' the whole time."
At one point, I read an article that refuted dark matter. (i'm certain i found it here on Slashdot) Dark matter was necessary to marshall the galaxy into its spiral shape. But these researchers realized that as the galaxies rotated, the stars at the outside edges of the galaxy were moving at a significant fraction (like 1 or 2 percent) of the speed of light. Relativity then causes the apparent mass of these stars to increase. Due to the squared term, 1% only leads to a 0.01% increase in appearent mass, but they ran the numbers for the distributions of stars, their orbital distances and velocities, and found that including this relativistic effect completely eliminated the need for dark matter in the formation of the shape of the galaxies.
It has been years, and dark matter is still being searched for. Was this research refuted? Does anyone remember it?
It isn't the extra screen space. Yes, for documentation and reference material, the extra space is nice. Code? Sure, why not. That's nice to have to. But real important part is running code in a debugger, without generating paint messages as you single step through code, causing infinite loops, or other non-deterministic behaviors. For that, an extra screen is critical, and a second computer to use for remote debugging is almost a requirement. Of course, it depends what you are developing.
Let's simplify this. Person takes elevator to top floor, then elevator returns to starting floor. No need to worry about counter weights. There has been a net change in the height distribution of mass, which will have caused a change rotation.
Vehicles that accelerate (including deceleration and mere changes in direction) on a road will have an effect as well. Add driving to a different elevation for greater effect.
Pumping oil out of the ground should also have an effect, as will other types of mining.
My wife isn't interested in playing with configuration settings, tweaking this, adjusting that and so on. A simpler UI, that does what she wants it to do, and no more, is what she's looking for.
Mmmm. Let's get government grants for the whole Flying Spaghetti Monsterism theme park. This gives, "think of the children" a whole new meaning. The children would start a grass roots effort to fight creationistic dogma with, "can you take us to Spaghetti Word."
Anybody want to start a Flying Spaghetti Monsterism theme park? It would be a lot of fun, and the government should be willing to fork over an equivalent amount of funds. Kidding aside, this is how the fight against creationism being taught along side evolution was won, and that was just a "paper" effort. Here, we can actually get government funding, and build something that would attract tourism dollars, educate people, and maybe turn a profit.
I don't know how bats do it, but CDMA allows several phones and several base stations to operate in overlapping areas on the same frequency. The transmission is "coded" in such a way that to everyone else, it just appears as noise. Kind of like your "voice" thought, but think of it as "language". You can be in a room with many people talking in different languages, and you can pick up a conversation in a language you know, and discard the rest as noise.
I had a love-hate relationship with my 150-in-1. I could build oscillators that generated tones, and change the tones, and what not. But it never really explained why/how it worked. It had PNP and NPN transistors... But the difference between them? No info. They act like switches? Excellent. They act like amplifiers? Ok... cool. Connect them like this and they oscillate. Say what?
I eventually moved up to a 250-in-1 kit with digital logic chips. That was cool! You could understand how a flip flop worked by tracing the logic 0's and 1's. Although analog circuits came before digital ones, digital ones are easier to grok, which leads to more learning. At least, in my case it did.
Add to that not wanting to be pregnant during the hot summer months, and wanting to avoid "cabin fever" (for those of us living with serious amounts of winter snow) with a newborn baby, and you're pretty much left with a spring birth.
Prior art? How about the reserve tank on a Motorcycle? You move a lever, and you can operate the motorcycle to the nearest gas-station.
I can't see this patent passing.
That the pulsars move relative to each other (and us) is true - but this is an extremely minor point. The pulsars all have very large masses, which means it would take something HUGE to alter their trajectory significantly. Until that happens, that large mass translates to very predictable movement.
The periodicity of the pulsar is more problematic. With a sudden introduction of mass, or a sudden readjustment in the matter of the pulsar, the frequency can abruptly change. And yet, this isn't even so much of an issue. The pulsars will be monitored from some location (Earth or otherwise), and changes to their behaviour can be uploaded to the Galactic Positioning System receivers shortly after the change is observed. The receivers might compute positions incorrectly in the interim, but more likely "dead reckoning", combined with other pulsar observations could be used to determine the erroneous input, and ignore it until the update.
A more serious "flaw" is that the pulsar emissions are not (at first blush) "marked" with an emission time. One pulse looks more or less like the next. If a pulse occurs once-a-second, this translates to 300,000 km between pulse fronts. If your positioning space exceeds this length, you might end up with ambiguity in your resulting position calculation. The other 3 pulsars will provide constraints, making certain "single pulse off-by-one" errors easily discarded. But as your location space grows, it becomes more than possible for multiple location solutions to a given set of pulse-front timings. With Earth's GPS system, each satellite's transmission is coded with both a satellite identifier and timing information, making this type of error impossible.
It the limit is 12 regenerations, and a regeneration is used up going from version 1.0 to 2.0, then we don't end with the 12th Doctor! There should be... must be... a 13th Doctor!
This seems awfully similar to the story of Richard Bliss's detention in Russia. He was using GPS to determine the locations to erect cellular base stations, and was charged with spying.
There are already laws which outlaw "assault", which is the threat of force. This pretty much would cover most kinds of bullying (ignoring, say, name calling). Cyberbullying would fall under this, and would be fairly easier to prove, since you have documented evidence of what was written -- it isn't heresay. Proving the person behind what was written was someone in particular, and that someone hadn't hijacked their account, would be the hard part. But "assault" is already illegal. You don't need to write a new "cyberbullying" law.
