New Proposed Path for Manned Trips to Mars: Let Mars' Gravity Capture Spacecraft 10

Posted by timothy
from the very-sun-tzu dept.
As illustrated in this article at io9.com, the conventional method considered for launching a manned craft to Mars might make less sense, even if it takes less time, than a more complicated but more efficient means akin to a method that's been already been successfully used to minimize the amount of fuel used in exploring both within and beyond the solar system. Known as the "Hohmann Transfer" method, this type of maneuver is known to be effective. But it is also quite expensive and relies very heavily on timing. Hence why a new idea is being proposed which would involve sending the spacecraft out ahead of Mars' orbital path and then waiting for Mars to come on by and scoop it up. This is what is known as "Ballistic Capture", a new technique proposed by Professor Francesco Topputo of the Polytechnic Institute of Milan and Edward Belbruno, a visiting associated researcher at Princeton University and former member of NASA's Jet Propulsion Laboratory. In their research paper, which was published in arXiv Astrophysics in late October, they outlined the benefits of this method versus traditional ones. In addition to cutting fuel costs, ballistic capture would also provide some flexibility when it comes to launch windows.

+ - Sony Hack Reveals MPAA's Big '$80 Million' Settlement With Hotfile Was A Lie->

Submitted by Anonymous Coward
An anonymous reader writes "For years, we've pointed out that the giant "settlements" that the MPAA likes to announce with companies it declares illegal are little more than Hollywood-style fabrications. Cases are closed with big press releases throwing around huge settlement numbers, knowing full well that the sites in question don't have anywhere near that kind of money available. At the end of 2013, it got two of these, with IsoHunt agreeing to 'pay' $110 million and Hotfile agreeing to 'pay' $80 million. In both cases, we noted that there was no chance that those sums would ever get paid. And now, thanks to the Sony hack, we at least know the details of the Hotfile settlement. TorrentFreak has been combing through the emails and found that the Hotfile settlement was really just for $4 million, and the $80 million was just a bogus number agreed to for the sake of a press release that the MPAA could use to intimidate others."

Today, there's no reason to not drive drunk. The expected cost of driving drunk is less than the cost of a cab. So it's rational to drive drunk.

It's only rational if you (a) value the price of a cab more than the risk of injury and death and (b) are a colossal arsehole.

Ask Slashdot: Dealing With Companies With Poor SSL Practices? 50

from the stochastic-protection dept.
An anonymous reader writes Despite recent highly-publicized hacking incidents making the news, companies continue to practice poor cyber-security. I signed-up to buy something from [an online vendor] and upon completing signup through HTTPS, was sent my username and password in plain-text through e-mail. This company has done everything in its power to avoid being contacted for its poor technical practices, including using GoDaddy's Domains By Proxy to avoid having even WHOIS information for their webmaster's technical contact from being found. Given such egregious behavior, what do you do when you're left vulnerable by companies flagrantly violating good security practice?

+ - The Dawn of Trustworthy Computing

Submitted by HughPickens.com
HughPickens.com (3830033) writes "Nick Szabo writes that when we use web services, we are relying on an architecture based on full trust in an unknown "root" administrator, who can control everything that happens on the server. They can read, alter, delete, or block any data on that computer at will. Even data sent encrypted over a network is eventually unencrypted and ends up on a computer controlled in this total way. With current web services we are fully trusting, in other words we are fully vulnerable to, the computer, or more specifically the people who have access to that computer, both insiders and hackers, to faithfully execute our orders, secure our payments, and so on. Compare this architecture to traditional commercial protocols, such as ticket-selling at a movie theater, that distribute a transaction so that no employee can steal money or resources undetected. There is no "root administrator" at a movie theater who can pocket your cash undetected. On the Internet, instead of securely and reliably handing over cash and getting our goods or services, or at least a ticket, we have to fill out forms and make ourselves vulnerable to identity theft in order to participate in e-commerce.

Recently a developing technology, often called "the block chain", is starting to change this. A block chain computer is a virtual computer, a computer in the cloud, shared across many traditional computers and protected by cryptography and consensus technology. A block-chain computer, in sharp contrast to a web server, is shared across many such traditional computers controlled by dozens to thousands of people. By its very design each computer checks each other's work, and thus a block chain computer reliably and securely executes our instructions up to the security limits of block chain technology, which is known formally as anonymous and probabilistic Byzantine consensus (sometimes also called Nakamoto consensus). Instead of the cashier and ticket-ripper of the movie theater, the block chain consists of thousands of computers that can process digital tickets, money, and many other fiduciary objects in digital form. "I think we see every week now somewhere between one and three entrepreneurs come in with blockchain ideas," says Chris Dixon. "There's definitely some momentum behind it.""

Sony PlayStation Network Back Up Now, Supposedly 34

Posted by timothy
from the nothing's-perfect dept.
jfruh (300774) writes Sony's PlayStation Network, brought down in a Christmas Day hacking attack, now seems to be back online. Of course, Sony also said the same thing on Saturday, but outages and problems lingered. From the article: At around 1 a.m. U.S. Eastern Time on Sunday, Sony declared its online gaming platform fixed and, as it had done the day before, blamed the problems on a distributed denial of service (DDoS) attack. ... The company jumped the gun early Saturday when it trumpeted that the PlayStation Network was gradually getting back to normal, announcing the good news at around 4 a.m. via its Ask PlayStation Twitter account and triumphantly changing the PlayStation Network status to “online” in the support website a few hours later.

Finn Linked To Lizard Squad Christmas Attack 36

Posted by timothy
from the little-griefers dept.
An anonymous reader writes Security researcher Mikko Hyppönen from F-Secure told the newspaper Helsingin Sanomat and Finland's MTV news that rumours have been circulating for several months about the Lizard Squad group of hackers who say they disrupted the two computer games console networks on Christmas Day. He confirmed that at least one of them is a Finn. One of the hackers, in a Skype interview from Finland by Britain's Sky News, said that the attack was carried out for amusement and to expose security flaws in the networks. Hyppönen told Helsingin Sanomat and MTV that his company has been aware of the hacker group for several months. 'According to our information, the group has members in the United States, Canada, England and at least one member in Finland,' he told MTV. The nationalities of other members that participated in the Christmas attack have not been confirmed. Hyppönen noted that these kinds of groups come and go, and that their members are usually young.
