The Raid-Proof Hosting Technology Behind 'The Pirate Bay' 129

from the pesky-vikings-and-their-lessons dept.
HughPickens.com writes Ernesto reports at TorrentFreak that despite its massive presence the Pirate Bay doesn't have a giant server park but operates from the cloud, on virtual machines that can be quickly moved if needed. The site uses 21 "virtual machines" (VMs) hosted at different providers, up four machines from two years ago, in part due to the steady increase in traffic. Eight of the VMs are used for serving the web pages, searches take up another six machines, and the site's database currently runs on two VMs. The remaining five virtual machines are used for load balancing, statistics, the proxy site on port 80, torrent storage and for the controller. In total the VMs use 182 GB of RAM and 94 CPU cores. The total storage capacity is 620 GB. One interesting aspect of The Pirate Bay is that all virtual machines are hosted with commercial cloud hosting providers, who have no clue that The Pirate Bay is among their customers. "Moving to the cloud lets TPB move from country to country, crossing borders seamlessly without downtime. All the servers don't even have to be hosted with the same provider, or even on the same continent." All traffic goes through the load balancer, which masks what the other VMs are doing. This also means that none of the IP-addresses of the cloud hosting providers are publicly linked to TPB. For now, the most vulnerable spot appears to be the site's domain. Just last year TPB burnt through five separate domain names due to takedown threats from registrars. But then again, this doesn't appear to be much of a concern for TPB as the operators have dozens of alternative domain names standing by.

Vrvana's Totem HMD Puts a Camera Over Each Eye 24

Posted by timothy
from the translucency-=-50-for-walking dept.
The Verge reports that Montreal startup Vrvana has produced a prototype of its promised (and crowd-funded) VR Totem headset. One interesting aspect of the Totem is the inclusion of front-facing cameras, one over each eye, the output of which can be fed to the displays. Reviewer Mike Futter has worn a prototype, and seems to be generally impressed, writing at Game Informer: Vrvana’s device offers 1080p resolution and features 90-degree field of view (the same as the Project Morpheus, but less than the Oculus Rift's 100-degree FOV), an OLED display, and adjustable lenses that can compensate for lens prescription. The HMD is usable by glasses wearers, but the tuning provides an option for those that don't want to wear corrective lenses while in VR. The system connects via HDMI to any source, and can model 3D (side-by-side) from game consoles as virtual reality right now. The Totem is currently compatible with all Oculus developer kit 1 applications, and Vrvana is working on getting DK2 experiences working. The prototype I wore was a good proof of concept, but didn't yet feature the OLED screen. This led to increased persistence due to the LCD. The head tracking also wasn't perfect, requiring some software tuning to prevent drift (something easily surmountable down the road). The clarity was impressive, rivaling some of the best experiences I've had with a Rift or Morpheus.

Researchers Propose a Revocable Identity-Based Encryption Scheme 70

Posted by timothy
from the now-who-was-I? dept.
jd writes Identity-based public key encryption works on the idea of using something well-known (like an e-mail address) as the public key and having a private key generator do some wibbly-wobbly timey-wimey stuff to generate a secure private key out if it. A private key I can understand, secure is another matter. In fact, the paper notes that security has been a big hassle in IBE-type encryption, as has revocation of keys. The authors claim, however, that they have accomplished both. Which implies the public key can't be an arbitrary string like an e-mail, since presumably you would still want messages going to said e-mail address, otherwise why bother revoking when you could just change address?

Anyways, this is not the only cool new crypto concept in town, but it is certainly one of the most intriguing as it would be a very simple platform for building mostly-transparent encryption into typical consumer apps. If it works as advertised. I present it to Slashdot readers to engender discussion on the method, RIBE in general and whether (in light of what's known) default strong encryption for everything is something users should just get whether they like it or not.

Small Restaurant Out-Maneuvers Yelp In Reviews War 235

Posted by timothy
from the slumming-with-the-stars dept.
An anonymous reader writes Yelp has, for the past year or so, garnered a reputation for extorting businesses into paying for advertising on their site. Allegations include incessant calls for advertising contracts, automatic listing of a business, and suppressing good reviews should a business decide to opt out of paying Yelp for listing them. One small Italian trattoria, however, may have succeeded in flipping Yelp's legally sanctioned business practices in its favor. The owners of Botto Bistro in Redmond, CA, initially agreed to pay for advertising on Yelp one year ago apparently because they were tired of getting calls from Yelp's sales team. But even after buying advertising, the owners claim that they kept receiving calls. So they started a campaign to get as many one-star reviews as they could, even offering 25% discounts to customers. As of this writing they have 866, and a casual perusal of them reveals enthusiastic tongue-in-cheek support for the restaurant. One-star reviews, once Yelp's best scare tactic, is now this particular business's badge of quality. And they didn't even have to pay Yelp for it.

An anonymous reader writes "Pascal-Emmanuel Gobry writes at The Week, "If you ask most people what science is, they will give you an answer that looks a lot like Aristotelian "science" — i.e., the exact opposite of what modern science actually is. Capital-S Science is the pursuit of capital-T Truth. And science is something that cannot possibly be understood by mere mortals. It delivers wonders. It has high priests. It has an ideology that must be obeyed. This leads us astray. ... Countless academic disciplines have been wrecked by professors' urges to look "more scientific" by, like a cargo cult, adopting the externals of Baconian science (math, impenetrable jargon, peer-reviewed journals) without the substance and hoping it will produce better knowledge. ... This is how you get people asserting that "science" commands this or that public policy decision, even though with very few exceptions, almost none of the policy options we as a polity have have been tested through experiment (or can be). People think that a study that uses statistical wizardry to show correlations between two things is "scientific" because it uses high school math and was done by someone in a university building, except that, correctly speaking, it is not. ... This is how you get the phenomenon ... thinking science has made God irrelevant, even though, by definition, religion concerns the ultimate causes of things and, again, by definition, science cannot tell you about them. ... It also means that for all our bleating about "science" we live in an astonishingly unscientific and anti-scientific society. We have plenty of anti-science people, but most of our "pro-science" people are really pro-magic (and therefore anti-science). ""

2 Mars Missions Set For Arrival, Both Prepare for Orbital Maneuvers 64

Posted by timothy
from the you-can-collude-but-don't-collide dept.
As reported by the BBC, NASA's Maven Mars orbiter has nearly reached the red planet, and will undergo a 33-minute rocket burn to slow its course. Monday's big manoeuvre on Maven's engines will place the satellite in a high, elliptical, 35-hour orbit around the planet. Confirmation of capture should be received on Earth shortly after 0220 GMT (2220 EDT Sunday; 0320 BST). "We should have a preliminary answer within just a few minutes after the end of the burn," said [principal investigator professor Bruce] Jakosky. In the coming weeks, engineers will then work to bring Maven into a regular 4.5-hour, operational orbit that takes the probe as close as 150km to Mars but also sends it out to 6,200km. India's first mission to Mars faces a critical test as it does a similar maneuver -- firing of a rocket to slow its travel as it approaches Mars orbit.

New MRI Studies Show SSRIs Bring Rapid Changes to Brain Function 128

Posted by timothy
from the depressing-thought-or-perhaps-not dept.
A story at the Los Angeles Times reports that researchers at the Max Planck Institute have found that Selective Serotonin Reuptake Inhibitors, various of which are widely used in anti-depressant medications, cause changes in healthy subjects' brain architecture just hours after ingestion. As the article mentions, one reason that this rapid change is surprising is that patients taking SSRIs to treat depression typically take considerably longer (weeks) to perceive a change in mood. A slice from the story: When more serotonin was available, this resting state functional connectivity decreased on a broad scale, the study found. This finding was not particularly surprising -- other studies have shown a similar effect in brain regions strongly associated with mood regulation. But there was a two-fold shock: Some areas of the brain appeared to buck the trend and become more interdependent. And all the changes were evident only three hours after the single dosage. ... The rapid connectivity shifts noted by the study might therefore be precursors to longer-term changes, perhaps starting with remodeling of synapses, the microscopic gaps where chemical neurotransmitters such as serotonin flood across to an adjacent brain cell, the study suggests. But this type of brain scanning can’t pick up changes at such a scale, so the hypothesis will have to be tested other ways[.] ... Study subjects did not have diagnoses of depression, so researchers will need to generate similar maps among those diagnosed with depression, and re-map them during and after depressive episodes, as well as after treatment, Sacher said. Comparisons might then show whether a certain initial architecture predicts treatment success.
