Comment Re:No solution selection? (Score 5, Informative) 241

Being a brazilian myself, I have to assure you it's not the electronic booth only. The whole election process is audited from beginning to end, software source code is independently audited, compiled and the binary is signed, in a full day cerimony.

The software activates itself an hour before the elections begin, and it must be closed at most a couple of hours after the election ends, or the booth is invalidated. It stores only two information: if an registered elector voted, and the vote itself, but no link is made between information. Data itself is encrypted and only the Superior Electoral Court President Judge has the key, which is he/she hands off to the Regional Judges only after all booths are recovered to the regional courts.

The whole thing is very straightforward, but the process has many control points and locks, so it would require an army of fraudsters for the elections to be cheated.

Comment Re:How they know... (Score 2) 175

They probably know this physical model will exhibit a magnetic field because they did a FEA and CFD simulations of the thing. So why then did it have to be built?

Because simulations do not substitute real experiments. For instance, why would one need LHC if the simulations show the Higgs boson? (Q.E.D.)


Submission + - Researchers Invent Everlasting Battery Material (eweekeurope.co.uk) 1

judgecorp writes: "Researcherse at Stanford University have invented a battery material that could allow batteries to go through 400,000 charging cycles instead of the 400 or so which today's Li-ion batteries can manage. Among the uses could be storing energy to even out the availability of renewable sources such as sun and wind."

Submission + - Roundtable discussion: When Politicians Distort Sc (thebulletin.org)

__aaqpaq9254 writes: Robert Socolow, Randy Olson and Roger Pielke, Jr. discuss and argue about the ways in which politicians distort science to the detriment of progress, and how scientists themselves aid this distortion through perceived arrogance. Olson takes issue with Socolow's use of the title: "Science: a Superior Way of Knowing", but all three seem to agree that the lack of basic scientific knowledge and real discussion has to change, and scientists need to be part of the effort. A great discussion that should be going on in all corners of public life.

An anonymous reader writes: There is free tool that can make Autodesk guys sweat. Tekla BIMsight won the overall innovation award in BATIMAT 2011 — the international building exhibition . Check out the video from the award ceremony in Paris. Tekla BIMsight is a tool to combine 3D models, review them and to share comments to other users.

Submission + - FBI scolds NASDAQ on out of date patches (computerworlduk.com)

DMandPenfold writes: NASDAQ’s ageing software and out of date security patches played a key part in the stock exchange being hacked last year, according to the reported preliminary results of an FBI investigation.

Forensic investigators found some PCs and servers with out-of-date software and uninstalled security patches, Reuters reported, including Microsoft Windows Server 2003. The stock exchange had also incorrectly configured some of its firewalls.

NASDAQ, which prides itself on running some of the fastest client-facing systems in the financial world, does have a generally sound PC and network architecture, the FBI reportedly found.

But sources close to the investigation told Reuters that NASDAQ had been an “easy target” because of the specific security problems found. Investigators had apparently expressed surprise that the stock exchange had not been more vigilant.


Submission + - The Aussies Have Built One Bad Ass Flight Simulato (gizmodo.com)

I Want One! writes: A fighter sim just isn't realistic unless it makes you throw up and scream for your mother, which is why the sadistic folks at Australia's Deakin University created the Universal Motion Simulator (UMS). It's a barebones cockpit attached to the end of a customised seven-meter robotic arm that can pull up to six Gs, it's uncomfortable enough to mimic external disturbances, mechanical failures and crash scenarios as well as normal flying. The system also monitors a pilot's brainwaves, pulse and other bodily functions to discover if they have necessary nerve.

Built by the Centre for Intelligent Systems Research (CISR), the Haptically-Enabled Universal Motion Simulator was partially funded by the government and military looking for a cheaper way to train pilots, and even drivers. What sets it apart from traditional simulators is the robot arm's ability to keep the rider moving or spinning on two axes at the same time, allowing it to better recreate the feeling of actual flight manoeuvres.


Submission + - Erasing time using a temporal hole (physorg.com)

kodiaktau writes: Scientists at Cornell have worked to create a demonstration backing Imperial College's work on temporal holes. The concept uses a split-time lens to interrupt an optical pulse, effectively bending the light and making the pulse curve around a dead-zone. A second splitter reverses the action. This means that data run between the splitters is effectively erased.

Submission + - Using lasers to see sound (io9.com)

wisebabo writes: Wow, what an awesome technique; because pressure waves (slightly) change the density of air and the speed of light (slightly) changes in mediums of varying density ("c" is only constant in a vacuum), you can theoretically map sound waves using light.

Well these guys have done it, using a laser, reflector and presumably other gadgets (interferometer?, camera, computer) to image at 100,000 fps(!) the sounds coming out of a speaker being tuned to higher frequencies. They use it to check the directionality of speaker designs but I'm wondering; would some of those new super-accurate "frequency combs" astronomers are now using greatly improve the accuracy/sensitivity of this so that it wouldn't have to be used in an enclosed setting? It would be cool to be able to point a (low power) possibly non-visible light laser into the sky (at a cloud perhaps) and see the pressure waves from the wind, storms, tornadoes, airplanes, wind turbines, traffic, rock concerts and what not. Maybe not today but how about ten years?

Science (and technology) the gift that keeps on giving. (No thanks to the ultra-conservative types like the Taliban who want to return us to the dark ages as far as I can tell: http://slashdot.org/comments.pl?sid=2513830&cid=37981690)


Submission + - Viacom, "Decimated By Piracy," Gives CEO $50M Rais (cnn.com)

esocid writes: Philippe P. Dauman, CEO of Viacom, led executive compensation raises this year with a $50.5 million raise, bringing his total annual compensation up to $84.5 (the majority of the 148.6% raise came in stock options). It's curious because Viacom continues to argue that it is in danger of capsizing unless radical changes are made to prevent piracy. Warner Bros. was in the same boat, complaining about not being able to compete with piracy, yet setting a record quarter for income. It's curious how people and politicians still buy their lamentations.

Submission + - Wicked Lasers Sells One-Watt Green Laser (wickedlasers.com)

cogent writes: "Wicked Lasers, famous for last year's 1000mW handheld blue laser, and infamous for its handling of six-month-long backorders, is now selling a green version. There are three power levels, each priced at $1/mW. Since the eye is far more sensitive to green than to blue, this is pretty much the state of the art in putting-dots-on-stuff technology. Wicked Lasers sent out an email, promising to handle backorders much better this time."

Submission + - The new risk of inbreeding: sperm donors (msn.com)

concealment writes: "“We have more rules that go into place when you buy a used car than when you buy sperm,” said Debora L. Spar, president of Barnard College and author of “The Baby Business: How Money, Science, and Politics Drive the Commerce of Conception.” “It’s very clear that the dealer can’t sell you a lemon, and there’s information about the history of the car. There are no such rules in the fertility industry right now.”

Unlike other countries, including Britain, France and Sweden, there are no limits in the United States on how many children a sperm donor can father. There are only guidelines issued by the American Society for Reproductive Medicine, a professional group that recommend restricting conceptions by individual donors to 25 births per population of 800,000."
