I don't have an iOS device nor an Android device, but after following your link, I may just have to go get an EVO or something, just to have access to its features:
GRAV: monitor the local gravitational field and acceleration
MAG: monitor the local magnetic field
ACO: acoustic analysis; waveform, frequency and sound level analysis of the ambient sound
GEO: display geographical information (enable GPS for full info)
EMS: scan the electromagnetic spectrum for radio signals -- currently displays cellular and WiFi signals (you have to enable the WiFi to get the latter)
SOL: display current solar activity data -- downloads current solar data in the background (may take a while) and displays it along with current images
That's just f*cking sweet. I can actually USE several of those... you know to do REAL work, not just read about aliens and space cowboys.
Ball lenses are handy things, and can be dangerous in direct sunlight - especially larger ones.
For most materials, like glass, their focal lengths generally extend away from their surface a distance less than their radius, and approach the surface as the wavelength extends into the infrarad, which means if you carry an uncovered glass sphere around on the beach or in the desert, you will burn your hand or set fire to your glove.
I learned this secondhand one day, at a beach gathering of Tolkien society geeks. One of them had taken to carrying around a 4" glass sphere she had found somewhere, calling it her "palantir." As the sun rose, she yelped and threw the thing to the ground. "It burned me!" she cried.
I had many times coupled fibers using ball lenses so I knew immediately what had happened. But I said "You know what that means, don't you? Sauron is watching you."
She wouldn't touch the thing again.
Also, speaking of ball lenses... you can use your head as a ball lens to extend the range of your car's wireless entry key fob. If you find yourself just out of range of your keys, simply put the transmitter about an inch behind your head, directly *opposite* the car. Your head is mostly transparent to the RF, but has a slightly different index of refraction from air/vaccum, thus acts as a lens. And since your head is approximately spherical, it works well enough to make a practical convergent lens.
I am the employee who generates value for your company. If your staff isn't generating more money than it costs, then either you're a poor manager, or your business plan has already accounted for that and hopes to recoup the losses later. If you want assured profits, then you need to compensate the employees who generate the wealth.
Yes, you steer the ship, but the employees are the engine, the sails, the hull, and the bilge pump. Without us, you'd be steering a canoe instead of a battleship. Take care of us like you'd take care of your ship, or else sooner or later you'll be swimming with the bankruptcy lawyers. (I hear they have dolls' eyes.)
Big corporations always win in the end. It's their world; we just live in it.
Yes, and this nation was founded on the ideal that the people (not businesses co-opting the rights of individuals) should rule, and that the three tyrannies of big warlords, big religion, and big business can be prevented.
I infer from your comment that you're simply content to see a return to the homo sapiens status quo: it took barely a 100 years for that experiment to fail. Well, many of us aren't content. In fact, more than a few of us are downright pissed.
We almost turned it around after the Great Depression, but the great war against Fascism transferred too much power back to the warlords and businesses. (Religion never really went away, though it seems more a less a tool for the other two these days.)
This story reminds me of a friend who, 20 years ago, was the IT person for a small aerospace startup that ran a Macintosh network with a single dial-in. (He may even be reading this: hats off, Mr Jones!)
They fired him, unamicably, and failed to change the passwords on the dialup (among other mistakes not later abused). So he decided to get his revenge by dialing in and sending multiple copies of a word document to every printer in the company (501 copies, iirc, guaranteed to empty every paper tray). The document was a quote from the Blonde Bimbo Office Manager ("BBOM"), in 36-point Helvetica:
"I've been at the bottom, and I've been at the top. I don't care how much dick I have to suck, I'm not going to be at the bottom again." Signed, [BBOM]
I was still there when it happened. The best part was, the BBOM took a stack of these printouts to every person in the building, shrieking: "Did you do this? Did YOU do this??" Nobody know who did it, in fact I think few even suspected the dialup.*
Now those are some lulz.
[*I didn't know it was him until months later, after the company laid off 90% of its staff, including me. Its doors shut a year later.]
If I'm going to spend $60 to go see a summer blockbuster, it better bust something instead of my already tremendous capacity for willful suspension of disbelief.

Review: Green Lantern
·
· Score: 1
I almost didn't take my son (age six and a half) to see Ryan Reynolds as Green Lantern, because it's PG-13 and (according to my son) "it might have kissing." (It did, but that's not what *I* was concerned about.) But it was Father's Day, and it was either that or the damn penguin thing... Cars 2 comes out next week, so we chose a more grown-up film. Or so we thought.
During the movie, I was alternately disappointed in the flimsy plot and shallow characters and worried that the giant ghost-like monster ("Parallax" - what a horrible name, not even scary) would frighten my son. I was reminded of the 2009 reboot of Star Trek -- both evoke very similar levels of disappointment and amazement that such crap passes muster these days. By the end of the movie, I was questioning my own objectivity: Am I just getting jaded in my old age? Or is it really that crappy? I concluded that if they want to spend $200M on something that would appeal to six-year-olds, then fine. I'll stick to Cartoon Network; they do much better plots and characterization for far less. Hell, even Ben 10 and Generator Rex have better developed plots. Crisis on Two Earths was fantastic compared to this superficial crap.
After the movie, I asked him how he liked it. I felt totally validated when he said, "It was good, but I still like the Justice League Unlimited. John Stewart is a better Green Lantern."
I should add, it's easier when the bugs find you. It takes a special kind of [karma|luck|uncanny statistical influence] to be a real bughunter. You have to be the kind of person who only needs to walk by a piece of dodgy tech in order to induce it to fail. That gives you an inkling of what life as a bughunter is really like.
On one hand, being an early adopter is just asking for trouble. Don't go there, unless you're being paid to. If it's been half-assed, you're going to find out -- and these days it seems like nearly everything new is also hemi-gluteous.
On the other hand, the stuff you design and build tends to be rather bulletproof, because you avoid unnecessary complexity, learn to identify and verify your assumptions, and test the living shit out of everything.
The machine itself is a portable, light-weight monitor, which can fit on a small trolley. It has 32 electrodes that are fitted around the patient’s head. A small, high-frequency electric current (too small to be felt or have any effect) is passed between two of the electrodes, and the voltages between other pairs of electrodes are measured in a process that takes less than one-thousandth of a second.
While we're still a long way away from a practical direct neural interface, this certainly looks like a step in the right direction. They've demonstrated that the measurements are possible, and at a sample rate that is useful. Certainly there's room for improvement in sensitivity, sample rate, and resolution as well as in miniaturization.
When they can reduce this from a trolleycart -sized instrument to something one can support on one's head, then we'll see some more practical and less academic applications. (Yes, like porn. And games. And real virtual reality control of UAVs and waldoes.) Keep in mind that in the 80's, realtime Heads-Up Displays were this large and cumbersome... now look at them.
It really is illuminating to see how little we know about the nature of consciousness and thought, and how far away we still are from technologically-aided introspection.
LOL, so instead, you're going to vote for the party that's actively fighting against your well being?
Did he say he was going to vote Republican? No.
There are other candidates, you know.
But the fact that most voters don't recognize third party candidates as legitimate is because the press won't. And the attitude that voting for such a candidate is "throwing your vote away" is the main reason we're stuck with this Coke vs. Pepsi two party system when what we really need right now is a drink of water.
(The proof is in the pudding. The biggest white collar crime in the history of the world was bought and paid for. And damn, what a return...)
The US government is about as uncorrupted as you're going to get.
Really? Then why is the US ranked 22nd, just above Uruguay, in the Corruption Perceptions Index? Why has the *perceived* corruption in the US been declining steadily since the Index was created?
Corruption has always been part of US politics, but kept in check at least for appearances' sake. But since the Iran/Contra scandal, it appears that the concern over appearances has eroded. Now you have a situation where the corrupted know that there will always be one-quarter to one-third of the US population who will oppose any criticism of the US, like this AC here, so all the kleptocrats have to do is wrap themselves in a flag and cheer "GO USA!" and they have an automatic voting block that will also faithfully defend them in public forums from Meet the Press to/b/.
Corruption is happening here because of the belief by so many that, "it can't happen here!"
Of course they did it legally. Rather than break the law, they just bought the lawmakers, and got their Glass-Steagall Act, which was basically just a license to commit exactly the kind of fraud that took place. Once they got the restrictions removed - regulations learned the hardway during the Great Depression and on the books for 60 years following -- it only took them 10 years to take us right back to another Great Depression.
Oh. I'm sorry, this is a Great Recession. We can't give the same name to the same mistake made twice. That would make it look like we're just a bunch of idiots doomed to repeat history...
anything else is politicians stealing from a group without favor to give to a group that has favor
Sorry, but that's just your opinion, and a minority opinion in the grand history of the USA. Coincidentally, your opinion is also held by an over-represented minority with a disproportionate voice because they won't shut up, congregate on soap boxes, and shout down (or character assassinate) those who hold opposing views.
These are facts: Since the United States rejected slavery and moved from an Agrarian economy to an Industrial one, the majority of its citizens (and I mean real people -- not wealthy businessmen hiding behind legal entities for the purpose of avoiding liability for white collar larceny, fraud and neglect -- but human beings), have consistently decided for most of its history that they also require a government that does more, e.g.: provides common universal social services such as education, healthcare, pensions, and mass transportation; maintains, manages and improves the commons, such as roads, ports, radio spectrum, and the environment; and most essentially puts checks and balances on the power of large, wealthy corporate persons to ensure that human beings aren't defrauded, neglected, poisoned, or robbed of their wealth or political influence and to prevent the tragedy of the commons -- something that those who have wanted to commit fraud, larceny and to pillage the commons have never been happy about at all.
I don't need to provide a citation for these claims, they're obvious to anyone who paid attention in school, or who was born before the Reagan administration. That was about the time that very wealthy special interests finally were able to influence the political process enough to weaken the government's ability to do the last bit, above, while the public was distracted with bread and circuses and watergate/vietnam burnout.
Now this is my opinion, and it's just as valid as yours: The idea that government has a role limited only to the four functions you list is fine in theory, but as soon as you try to make it work in practice, it reverts to a plutocracy -- or worse. So it's no coincidence that its plutocrats and plutocrat-wannabe's (and worse) are the ones who embrace this brand of libertarianism, and are pissed off that they haven't just been handed a license to pillage the commons, steal from the public, and generally be free to behave like sociopaths because they are superior to the hoi polloi. And now that they've had their way with our government for 25 years or so, the commons are being looted, polluted and denuded, the economy is in shambles, and we're well on our way to becoming a full-fledged plutocracy -- or worse.
The claim that a government which doesn't protect the public from these sociopaths, and which makes public improvements accessible equally to all, is stealing from one group and giving to another that has favor is the epitome of ironic projection. Because the position that government should only soldier, police, convict and incarcerate is held mainly by people who wish to concentrate wealth and power in the hands of a favored few -- themselves -- and would use the soldiers and police to maintain that status quo.
But that's just my opinion, after fifty years of observation.
And many other good ones under this same story. When "redundant" is right next to "insightful" the moderation process REALLY needs a confirmation step, or a way to undo a moderation without undoing every one in the story.
The circuit the team built is a broadband radio-frequency mixer, a fundamental component of radios that processes signals by finding the difference between two high-frequency wavelengths.
Did someone paid directly by IEEE write that? "Two high-frequency wavelengths?"
The device is a nonlinear summing element. In other words, it has a transfer function of the form y=Sum(ax^n) for integer values of n from zero to at least 2. A very common example is a diode. But it could also be a transistor in the saturation region, or something more esoteric.
Due to the nonzero second-order transfer function coefficient, provides not only the superposed sum of the two signals at their original frequency, but also at the sum and difference of the two input frequencies. Add filters to throw away the parts you don't want, and you can make a modulator, a frequency upconverter, or a downconverter... all of these are used every day inside things you probably have in your pocket or purse, from cellphones to car stereos, television receivers to communications satellites.
But basically, it does the same thing a diode does... just faster.
Anything with a big 'ol vibrating transformer in it will make a similar noise.
No. Those make the wokk wokk wokk sound when they transform from a 14-inch phallus that goes bzzzzzzzzrrrrrrzzzzzrrrrrrrrrrzzz into a Harley-Davidson V-Rod Muscle 1250, that goes chugchug chugchug chugchug... ROARRRRR!. My lesbian aunt keeps one in her purse.
Oh. Sorry. I thought you said "transforming vibrator."
Did you read the caption? They're crew on a JSTARS. That's a radar plane. They blast megawatts of RF thru the sky. They need that shielding on their cables, or else their equipment is going to be fried.
And the radars are very sensitive to interference. RF emissions are not going to bring down the plane, but it's going to reduce the sensitivity of their GMTI algorithms, or obscure a target they could otherwise detect.
Furthermore, it's military cable. They don't buy anything that's not shielded and jacketed, they have high standards ya know... and people whose jobs exist solely to make sure they're met.
I was just playing with a military radio terminal last week, and you could use the USB cable that went between the receiver and toughbook as an effective weapon if necessary.
