Submission + - Android Ice Cream Sandwich Source Released (google.com)

grcumb writes: Looks like the folks at Google have made good on their promise to release the Android 4.0 source code. Android software engineer Jean-Baptiste Queru writes: "Hi! We just released a bit of code we thought this group might be interested in. Over at our Android Open-Source Project git servers, the source code for Android version 4.0 (Ice Cream Sandwich) is now available."

"This is actually the source code for version 4.0.1 of Android, which is the specific version that will ship on the Galaxy Nexus, the first Android 4.0 device. In the source tree, you will find a device build target named "full_maguro" that you can use to build a system image for Galaxy Nexus. Build configurations for other devices will come later."

If the Cyanogen elves get busy Daddy just might be getting a new ROM for Christmas....

Submission + - Macroscopic wave–particle duality (archives-ouvertes.fr)

advid.net writes: A 'walking' drop on a liquid surface behave like a particle with wave properties: diffraction, interference patterns, vibration quantization.

First, in a vibrating container they put a liquid like silicon oil, vibrations are just bellow the Faraday instability threshold. Then a drop of the same liquid is dropped on the surface, but it does not coalesce, it bounces. And further bounces make a static wave pattern on the liquid surface just bellow the drop and its immediate neighborhood. As the spike grows, instability increases and the drop slides down the spike, and start moving horizontally.

Then they have a combo object drop+wave pattern moving at 1/10th the speed of wave in this liquid, straight. They call it a walker.

What is really amazing is that the wave pattern below the drop has some kind of memory: it has accumulated energy from several drop bounces. It can also make the drop see "forward", as the small wave pattern bounces back from nearby obstacles. So the drop is "aware" of its environment and "recall" the path it has followed.

Diffraction is observed and explained by the multiple reflexions the wave makes when the drop passes through a small hole, randomizing the wave pattern and the angle of the path afterward. Interference patterns observed are explained a la de Broglie: as the drop passes through one of the two holes, its associated wave passes through both, carrying forward the message of the second hole to the drop and changing the statistical repartition of the drop's path direction. One more stunning result: they are circling the drop by moving the container (Coriolis), then the associated wave adopts a discrete series of pattern, depending on the speed and radius. Very much like the energy quantization of electrons.

Comment Who Gave Robert Reich the Authority to Say How S&a (Score 1) 1040

S&P is a ratings agency.

As a private entity, its valuations (sold to investors) are its main cash cow. You don't have to believe what they say--that's your prerogative. If you think what they say is BS, out of touch with reality, or a "$X trillion mistake," that's what the other rating agencies are for (Fitch, Moody's, etc.).

Who gave S&P the authority? Private enterprise gave them that. They happen to be very good at gauging these things, which is why people tend to trust them.

OK, so they were manipulated (or manipulating) for mortgage pass-through securities during the 2008 credit crisis. They fell asleep at the wheel, should have been paying more attention, should have been better at figuring it out. They could have been more savvy to realize that the CDS market was getting bigger and bigger all at AIG's expense. But they weren't. That also happens to NOT be their primary market. Fannie and Freddie are supposed to be responsible for securing mortgages. S&P is all about stocks, bonds, and indices.

Think of how many times does S&P get it right compared to how many times it is off base. If there is one plane crash, does everyone decide not to fly ever again?

I'm no big fan of S&P, but at the end of the day, S&P is answerable to its investors and its clients, no one else. Certainly not Robert Reich. Who gave HIM the authority?

Actually, there is zero (0) evidence that Sir Francis Bacon wrote the works of William Shakespeare of Stratford-upon-Avon.

Nobody even thought the idea possible until "evidence" came from a Delia Bacon (no relation) who was a total nutter.

Then people like Mark Twain started to probe into some of the "biographies" of the Bard written by people who had no concept of history or any business writing such biographies, and a conspiracy-that-was-never-a-conspiracy was born as a result. Now there are a wide range of theories from Marlowe to de Vere to UFOs to Elvis.

Two hundred years from now, people are going to claim that someone else was Walt Disney because there is no way he could have drawn every single cartoon by hand.

Comment So why not a Patent 2.0 system? (Score 2) 102

Grandfather it in like this: if you file a patent by the rules of Patent 2.0, then you can no longer sue or be sued using the Patent 1.0 system. Furthermore, you have to abandon all existing Patent 1.0 lawsuits. In exchange, any Patent 1.0 lawsuits filed against your organization are void.

How much would that level the playing field?

Florida Man Sues WikiLeaks For Scaring Him 340

Stoobalou writes "WikiLeaks founder Julian Assange has been accused of 'treason' by a Florida man seeking damages for distress caused by the site's revelations about the US government. From the article: 'David Pitchford, a Florida trailer park resident, names Assange and WikiLeaks as defendants in a personal injury suit filed with the Florida Southern District Court in Miami. In the complaint filed on 6th January, Pitchford alleges that Assange's negligence has caused "hypertension," "depression" and "living in fear of being stricken by another heart attack and/or stroke" as a result of living "in fear of being on the brink of another nuclear [sic] WAR."' Just for good measure, it also alleges that Assange and WikiLeaks are guilty of 'terorism [sic], espionage and treason.'"

I really hope the SEC comes down hard on this. Using an SPV (special-purpose vehicle) as a "single investor" is breaking the spirit of the law, if not the letter of the law. This deal makes Goldman Sachs an insider trading infinite fraud machine with the power to print as much money as they want and defraud as many investors as they can. As usual, you are doomed if you can't get on the investment bandwagon and get some of that "good old privately traded Facebook stock", and doubly doomed if you are one of the investors who actually does buy the stock, only to be killed by Goldman's credit default swaps when the bubble pops and you find out that the stock is worthless. In no universe should it be legal, but you know Goldman, they're Too Big to Fail. Get ready for the taxpayer to foot the bill (again).

Thank you, Firefox, for blocking them.

The comments here on Slashdot are far, far more useful than the original article, which I found to be rather trite and derivative ("don't do X. don't do ~X").

One Night Stands May Be Genetic 240

An anonymous reader writes "So, he or she has cheated on you for the umpteenth time and their only excuse is: 'I just can't help it.' According to researchers at Binghamton University, they may be right. The propensity for infidelity could very well be in their DNA. In a first of its kind study, a team of investigators led by Justin Garcia, a SUNY Doctoral Diversity Fellow in the laboratory of evolutionary anthropology and health at Binghamton University, State University of New York, has taken a broad look at sexual behavior, matching choices with genes and has come up with a new theory on what makes humans 'tick' when it comes to sexual activity. The biggest culprit seems to be the dopamine receptor D4 polymorphism, or DRD4 gene. Already linked to sensation-seeking behavior such as alcohol use and gambling, DRD4 is known to influence the brain's chemistry and subsequently, an individual's behavior."

Comment Re:Trade Secrets? (Score 1) 250

What Stock Exchange regulators? And just how, exactly?

Normally a company has a simple profit and loss summary. With banks, it's an entirely different matter. Banks have the power to move things off their balance sheet completely--poof! That's the whole point of most structured products, including credit derivatives.

Until the Wall Street reform bill got passed, nobody had the power to do anything about the situation at all. Now it's ostensibly fixed, but that takes time before the new regulators can even get a handle on what's been going on for the last 2-3 years. It's still easy peasy when most financial instruments can be traded over the counter (i.e., not through an exchange), without rules (especially for the big banks, who have special immunity) and don't have to be recorded.

It's only a matter of time before Goldman is the next Enron, only far, far worse. They may even get away with it.

And their "big secret" is... ...the emperor has no clothes and their balance sheet is entirely made up. They simply make up the number they want and use alchemy, I mean, custom derivatives traded over the counter with SPVs (special purpose vehicles).

Their technology is 100% proprietary and in house, at the programming language (Slang), database (SecDB) and networking levels (yep, even custom screen editors, no IDEs for Goldman) for added obfuscation. They brag internally about how much they spend on technology, the bulk of which is spent on training people just out of school on their proprietary system. It is almost impossible to audit.

1928 Time Traveler Caught On Film? 685

Many of you have submitted a story about Irish filmmaker George Clarke, who claims to have found a person using a cellphone in the "unused footage" section of the DVD The Circus, a Charlie Chaplin movie filmed in 1928. To me the bigger mystery is how someone who appears to be the offspring of Ram-Man and The Penguin got into a movie in the first place, especially if they were talking to a little metal box on set. Watch the video and decide for yourself.

I don't think it's a question of the technology. We already have things that fly, and I remember a flying car model that worked coming out about 15 years ago. It's a question of fuel efficiency (discussed in another thread) the allocation of resources, and social priorities.
