Quite true about not being able to control the state. However, quantum mechanics requires either nonlocal effects or no hidden variables (no well defined state). The latter is consistent with the Copenhagen interpretation, in which Schrödinger's cat is both alive and dead until you observe it. In the de Broglie-Bohm interpretation of quantum mechanics, all particles have a well defined but unknown state and "entanglement" is actually an inherently nonlocal effect that occurs when a "measurement" is made (the "measurement" causes a nonlocal perturbation).

However, because the entangled particles cannot be moved faster than light (FTL), even the nonlocal effects in the de Broglie-Bohm interpretation do not allow FTL communication.

As a side note, the similarities between this ER=EPR conjecture and the de Broglie-Bohm interpretation seem quite interesting. I wonder if the two could be equated.

+ - NASA's Rocket Maker To Begin 3D Printing Flight-Ready Components ->

Submitted by Lucas123
Lucas123 writes: United Launch Alliance (ULA), the company that makes rockets for NASA and the U.S. Air Force, plans to 3D print more than 100 flight-ready components for its next-gen Vulcan rocket. The company also just printed its first flight-ready component, a new Environmental Control System for its current Atlas V rocket. The ECS assembly had previously contained 140 parts that were made by third party suppliers, but ULA was able to reduce the parts to just 16, resulting in a 57% part-cost reduction. Along with cost reduction, ULA said 3D printing frees it from contracts with parts providers who may or may not deliver on time depending on whether the deem the rocket maker a priority at any given time. The company, which launches 12 rockets each year, is also hoping to use 3D printing for a more traditional role — rapid prototyping of parts. "We have a long list of [parts] candidates to evaluate — over 100 polymer parts we're considering and another 50 or so metal parts we're considering," said Greg Arend, program manager for additive manufacturing at ULA.

+ - FBI can't cut Internet and pose as cable guy to search property->

Submitted by Anonymous Coward
An anonymous reader writes: Harrah for some common sense:
A federal judge issued a stern rebuke Friday to the Federal Bureau of Investigation's method for breaking up an illegal online betting ring. The Las Vegas court frowned on the FBI's ruse of disconnecting Internet access to $25,000-per-night villas at Caesar's Palace Hotel and Casino. FBI agents posed as the cable guy and secretly searched the premises.

The government claimed the search was legal because the suspects invited the agents into the room to fix the Internet. US District Judge Andrew P. Gordon wasn't buying it. He ruled that if the government could get away with such tactics like those they used to nab gambling kingpin Paul Phua and some of his associates, then the government would have carte blanche power to search just about any property.

+ - DIA Polygraph Countermeasure Case Files Leaked

Submitted by George Maschke
George Maschke writes: AntiPolygraph.org (of which I am a co-founder) has published a set of leaked Defense Intelligence Agency polygraph countermeasure case files along with a case-by-case analysis. The case files, which include polygraph charts and the exact questions used, suggest that the only people being "caught" trying to beat the polygraph are those using crude, unsophisticated methods that anyone who actually understood polygraph procedure and effective countermeasures (like, say, a real spy, saboteur, or terrorist) would ever use. AntiPolygraph.org has previously published polygraph community training materials on countermeasures that indicate they lack the ability to detect countermeasures like those described in our free book, The Lie Behind the Lie Detector (PDF) or in former police polygraph examiner Doug Williams' manual, How to Sting the Polygraph . Williams, who was indicted last year after teaching undercover federal agents how to pass a polygraph, is scheduled to stand trial on May 12 in Oklahoma City.

+ - FBI overstated forensic hair matches in nearly all trials before 2000->

Submitted by schwit1
schwit1 writes: The Justice Department and FBI have formally acknowledged that nearly every examiner in an elite FBI forensic unit gave flawed testimony in almost all trials in which they offered evidence against criminal defendants over more than a two-decade period before 2000.

Of 28 examiners with the FBI Laboratory's microscopic hair comparison unit, 26 overstated forensic matches in ways that favored prosecutors in more than 95 percent of the 268 trials reviewed so far, according to the National Association of Criminal Defense Lawyers (NACDL) and the Innocence Project, which are assisting the government with the country's largest post-conviction review of questioned forensic evidence.

The cases include those of 32 defendants sentenced to death. Of those, 14 have been executed or died in prison, the groups said under an agreement with the government to release results after the review of the first 200 convictions.

+ - Is This Justice? EFF pushes Pasco County to be sensible with 8th Grade "Hacker"-> 1

Submitted by Anonymous Coward
An anonymous reader writes: A 14-year-old eighth grader in Florida, Domanik Green, has been charged with a felony for “hacking” his teacher’s computer. The “hacking” in this instance was using a widely known password to change the desktop background of his teacher’s computer with an image of two men kissing. The outrage of being charged with a felony for what essentially amounts to a misguided prank should be familiar to those who follow how computer crimes are handled by our justice system.

Charging decisions and punishment should be proportional to the harm a person causes. The only thing that “making an example” out of Domanik Green accomplishes is to make an example of how out of whack our computer crime laws—and the prosecutorial discretion that accompanies it—are. We call on Pasco County to do the sensible thing and not ruin Domanik Green’s life. This is not justice.

Now what do you think?

Fully 3D circuitry is limited more by the requirement to have a single-crystal and the economics of circuit fabrication, than by power density. Furthermore, neuromorphic computing (which is advancing rapidly) has the potential to solve power density and yield issues, but Si wafers are still cheap compared to mask steps.

Some kind of platform docking mechanism does seem like a reasonable solution. Clearly they're close enough that such an addition should add enough tolerance for a high recovery fraction. However, it also looks like they're close enough that it may just take some more software calibration.
