How Microwave Transmission Is Linking Financial Centers At Near-Light Speed 236

from the faster-than-you-can-read dept.
The L.A. Times has a short but compelling article about the state of the art (and coming state of the art) in dedicated networking technology in one of the applications where you'd expect the customers to care most about it: connecting financial trading centers. Milliseconds count, and the traders count milliseconds. From the article, one example: "[New York-based networking company] Strike, whose ranks include academics as well as former U.S. and Israeli military engineers, hoisted a 6-foot white dish on a tower rising 280 feet above the Nasdaq Stock Market's data center in Carteret, N.J., just outside New York City. Through a series of microwave towers, the dish beams market data 734 miles to the Chicago Mercantile Exchange's computer warehouse in Aurora, Ill., in 4.13 milliseconds, or about 95% of the theoretical speed of light, according to the company. Fiber-optic cables, which are made up of long strands of glass, carry data at roughly 65% of light speed."

The much-discussed health care finance sign-up website HealthCare.gov has benefited from the flurry of improvements that have been thrown at it in the last several weeks. Centers for Medicare and Medicaid spokesman Aaron Albright told Fox News Saturday that "[w]ith the scheduled upgrades last night and tonight, we're on track to meet our stated goal for the site to work for the vast majority of users." CMM spokeswoman Julie Bataille. "said the installation of new servers Friday night helped improved the response times and error rates, even with heavier-than-usual weekend traffic." If you've used the site this weekend, what has your experience been like?

Seattle diners who want to take their food-tweeting pictures with Google glass were already facing a preemptively hostile environment; now (in a different restaurant), a diner's been asked to remove his Google Glass headset, or leave. He chose to leave. Maybe Faraday cages and anti-surveillance features will become the norm at the restaurants where things like Glass are most likely to appear.

jones_supa writes "Talouselämä Magazine met Jolla CEO Tomi Pienimäki and asked a puzzling question. If Jolla truly is compatible with Android devices, is Jolla going to let individual users to install the Sailfish operating system on the Android devices that they already have? Pienimäki answers: 'That is the plan. We are on device business and OS business. It is fairly easy to install the OS on Android devices'. He says that especially in China, changing firmwares is a mainstream thing. About half of the smartphone buyers are upgrading their older or cheaper devices with a better version of Android. Therefore, Jolla's plan is to get some Sailfish installations sneaked in, too."

Google Supercomputers Tackle Giant Drug-Interaction Data Crunch 50

ananyo writes "By analysing the chemical structure of a drug, researchers can see if it is likely to bind to, or 'dock' with, a biological target such as a protein. Researchers have now unveiled a computational effort that used Google's supercomputers to assesses billions of potential dockings on the basis of drug and protein information held in public databases. The effort will help researchers to find potentially toxic side effects and to predict how and where a compound might work in the body. 'It's the largest computational docking ever done by mankind,' says Timothy Cardozo, a pharmacologist at New York University's Langone Medical Center, who presented the project at the US National Institutes of Health's High Risk–High Reward Symposium in Bethesda, Maryland. The result, a website called Drugable, is still in testing, but it will eventually be available for free, allowing researchers to predict how and where a compound might work in the body, purely on the basis of chemical structure."

Intel Linux Driver Now Nearly As Fast As Windows OpenGL Driver 113

from the picture-parity dept.
An anonymous reader writes "Intel's open-source Linux graphics driver is now running neck-and-neck with the Windows 8.1 driver for OpenGL performance between the competing platforms when using the latest drivers for each platform. The NVIDIA driver has long been able to run at similar speeds between Windows and Linux given the common code-base, but the Intel Linux driver is completely separate from their Windows driver due to being open-source and complying with the Linux DRM and Mesa infrastructure. The Intel Linux driver is still trailing the Windows OpenGL driver in supporting OpenGL4."

Bitcoin Miners Bundled With PUPs In Legitimate Applications Backed By EULA 194

Posted by timothy
from the informed-consent-it-ain't dept.
hypnosec writes "Bitcoin miners are being integrated with third party potentially unwanted programs (PUPs) that come bundled with legitimate applications. These miners surreptitiously carry out Bitcoin mining operations on the user's system consuming valuable CPU time without explicitly asking for user's consent. Malwarebytes, the company which found evidence of these miners, first came across such an instance of a Bitcoin miner when one of the users of its software requested for assistance on November 22 through a forum post. The user revealed that 'jh1d.exe' was taking up over 50 percent of the CPU resource and even after manual deletion the executable was re-appearing. Malwarebytes dug deeper into this and found traces of a miner 'jhProtominer,' a popular mining software that runs via the command line". However, it seems that the company behind the application has a specific clause 3 in EULA that talks about mathematical calculations similar to Bitcoin mining operation. This means that the company behind the software can and will install Bitcoin miners and use system resources to perform operations as required to mine Bitcoins and keep the rewards for themselves."

Reverse Engineering the Technical and Artistic Genius of Painter Jan Vermeer 70

Posted by timothy
from the now-just-reconstruct-his-time-machine dept.
Hugh Pickens DOT Com writes "Kurt Anderson has an interesting read at Vanity Fair about Dutch painter Jan Vermeer, best known for 'Girl with a Pearl Earring,' and the search for how he was able to achieve his photo-realistic effects in the 1600s. Considered almost as mysterious and unfathomable as Shakespeare in literature, Vermeer at age 21, with no recorded training as an apprentice, began painting masterful, singular, uncannily realistic pictures of light-filled rooms and ethereal young women. 'Despite occasional speculation over the years that an optical device somehow enabled Vermeer to paint his pictures, the art-history establishment has remained adamant in its romantic conviction: maybe he was inspired somehow by lens-projected images, but his only exceptional tool for making art was his astounding eye, his otherworldly genius,' says Anderson. To try to learn how Vermeer was able to achieve such highly realistic painting, American inventor and millionaire Tim Jenison spent five years learning how to make lenses himself using 17th-century techniques, mixed and painted only with pigments available in the late 1600s and even constructed a life-size reproduction of Vermeer's room with wooden beams, checkerboard floor, and plastered walls. The result has been a documentary movie, Tim's Vermeer, by magicians Penn & Teller that may have resolved the riddle and explains why it has remained a secret for so long. 'The photorealistic painters of our time, none of them share their techniques,' says Teller. 'The Spiderman people aren't talking to the Avatar people. When [David] Copperfield and I have lunch, we aren't giving away absolutely everything.'"

AI Reality Check In Online Dating 192

Posted by timothy
from the alright-cherub dept.
mikejuk writes "Researchers have developed an online dating system that not only matches you with partners you'll find attractive, but who are also likely to find you attractive too. The researchers at the University of Iowa have addressed an underlying problem of online dating sites. There's no doubt that such sites are ever increasing in popularity, and have good algorithms taking into account the reported likes, interests and hobbies of the person looking for a partner to come up with a potential match. What's less well catered for is the trickier aspect of the reciprocal interest – you may think person x looks nice, but will they find you equally attractive? The problem here is that if you are Average Joe and try asking out Supermodels Ann, Barbara and Cheryl, you're unlikely to get a reply. Well, not a printable one, anyway. So coming up with yet another supermodel for you to sob over isn't a lot of help.Instead, the researchers add a note of reality by analyzing the replies you get, and use this to work out how attractive you are. This is a scary thought for many of us, and one we may well not want an honest answer to. The results are used to recommend people who might actually reply if you get in contact with them. Fortunately for the attractively challenged, the research is still just that – research. However, given the fact the online dating market is worth around $3 billion a year, chances are someone is going to make use of this. We have been warned."

Ask Slashdot: DIY Computational Neuroscience? 90

from the next-week-we-cure-all-known-diseases dept.
An anonymous reader writes "Over the last couple years, I have taught myself the basic concepts behind Computational Neuroscience, mainly from the book by Abbott and Dayan. I am not currently affiliated with any academic Neuroscience program. I would like to take a DIY approach and work on some real world problems of Computational Neuroscience. My questions: (1) What are some interesting computational neuroscience simulation problems that an individual with a workstation class PC can work on? (2) Is it easy for a non-academic to get the required data? (3) I am familiar with (but not used extensively) simulators like Neuron, Genesis etc. Other than these and Matlab, what other software should I get? (4) Where online or offline, can I network with other DIY Computational Neuroscience enthusiasts? My own interest is in simulation of Epileptogenic neural networks, music cognition networks, and perhaps a bit more ambitiously, to create a simulation on which the various Models of Consciousness can be comparatively tested."

China's First Lunar Lander To Launch Today; Manned Mission Planned By 2030 137

c0lo writes "A Chinese Long March rocket is scheduled to blast off to the Moon on Sunday evening at about 6pm UTC carrying a small robotic rover that will touch down on to the lunar surface in about two weeks' time – the first soft landing on the Earth's only natural satellite since 1976. China has been methodically and patiently building up the key elements needed for an advanced space programme — from launchers to manned missions in Earth orbit to unmanned planetary craft — and it is investing heavily. After only 10 years since it independently sent its first astronaut into space, China is forging ahead with a bold three-step programme beginning with the robotic exploration of possible landing sites for the first Chinese astronauts to set foot on lunar soil between 2025 and 2030. Prof Ouyang Ziyuan of the department of lunar and deep space exploration and an adviser to the mission commented to the BBC on the scale of Chinese thinking about the Moon. He said the forthcoming venture would land in an ancient crater 400km wide called Sinus Iridum, thought to be relatively flat and clear of rocks, and explore its geology. China.org.cn promised live coverage of the event."

The Dismantling of POTS: Bold Move Or Grave Error? 582

Posted by timothy
from the hard-to-cook-without-pots dept.
New submitter TheRealHocusLocus writes "The FCC is drafting rules to formalize the process of transition of 'last-mile' subscriber circuits to digital IP-based data streams. The move is lauded by AT&T Chairman Tom Wheeler who claims that significant resources are spent to maintain 'legacy' POTS service, though some 100 million still use it. POTS, or 'Plain Old Telephone Service,' is the analog standard that allows the use of simple unpowered phone devices on the wire, with the phone company supplying ring and talk voltage. I cannot fault progress, in fact I'm part of the problem: I gave up my dial tone a couple years ago because I needed cell and could not afford to keep both. But what concerns me is, are we poised to dismantle systems that are capable of standing alone to keep communities and regions 'in-touch' with each other, in favor of systems that rely on centralized (and distant) points of failure? Despite its analog limitations POTS switches have enforced the use of hard-coded local exchanges and equipment that will faithfully complete local calls even if its network connections are down. But do these IP phones deliver the same promise? For that matter, is any single local cell tower isolated from its parent network of use to anyone at all? I have had a difficult time finding answers to this question, and would love savvy Slashdot folks to weigh in: In a disaster that isolates the community from outside or partitions the country's connectivity — aside from local Plain Old Telephone Service, how many IP and cell phones would continue to function?"

An anonymous reader writes "Google really wants Chrome apps to take off. Not only has the company added rich notifications, in-app payments, and an app launcher into its browser, but now it's developing ephemeral apps that launch by just clicking a link. There are two separate components here. Ephemeral apps (you can enable this under the chrome://flags/#enable-ephemeral-apps flag) let you try a Chrome app before installing it. Linkable ephemeral apps (under the chrome://flags/#enable-linkable-ephemeral-apps flag) meanwhile allow you to launch said apps from hyperlinks."
