An anonymous reader writes "MIT is claiming they can make the Internet faster if we let computers redesign TCP/IP instead of coding it by hand. They used machine learning to design a version of TCP that's twice the speed and causes half the delay, even with modern bufferbloated networks. They also claim it's more 'fair.' The researchers have put up a lengthy FAQ and source code where they admit they don't know why the system works, only that it goes faster than normal TCP."

An anonymous reader writes with this excerpt from ABC News: "A former student was sentenced to a year in prison for rigging his school elections at California State University-San Marcos so he could become student president, court documents show. Matthew Weaver, 22, was charged in January with wire fraud, access device fraud and unauthorized access to a computer. He pleaded guilty in March, admitting that he had stolen the email passwords of more than 740 students and used them to vote for himself 630 times during the student elections in March 2012... Right before the voting ended, on March 15, 2012, officials noticed 259 votes coming from another IP address. Officials tracked the IP address to a classroom, and found Weaver sitting there. There was only one other student in the lab, according to court documents. A university police officer arrested Weaver and seized his bag, subsequently discovering that he had stashed the keyloggers there."
Bruce Schneier points out on his blog a proposal to use electronic randomizers at airport security checkpoints. Schneier writes there: "I've seen something like this at customs in, I think, India. Every passenger walks up to a kiosk and presses a button. If the green light turns on, he walks through. If the red light turns on, his bags get searched. Presumably the customs officials can set the search percentage. Automatic randomized screening is a good idea. It's free from bias or profiling. It can't be gamed. These both make it more secure. Note that this is just an RFI from the TSA. An actual program might be years away, and it might not be implemented well. But it's certainly a start." In this case, the proposal is for randomizers that direct passengers to particular conveyor-belt lines for screening.
Vigile writes "While 4K displays have been popping up all over the place recently with noticeably lower prices, one thing that kind of limits them all is a 30 Hz refresh rate panel. Sony is selling 4K consumer HDTVs for $5000 and new-comer SEIKI has a 50-in model going for under $1000 but they all share that trait — HDMI 1.4 supporting 3840x2160 at 30 Hz. The new ASUS PQ321Q monitor is a 31.5-in 4K display built on the same platform as the Sharp PN-K321 and utilizes a DisplayPort 1.2 connection capable of MST (multi-stream transport). This allows the screen to include two display heads internally, showing up as two independent monitors to some PCs that can then be merged into a single panel via AMD Eyefinity or NVIDIA Surround. Thus, with dual 1920x2160 60 Hz signals, the PQ321Q can offer 3840x2160 at 60 Hz for a much better viewing experience. PC Perspective got one of the monitors in for testing and review and found that the while there were some hurdles during initial setup (especially with NVIDIA hardware), the advantage of a higher refresh rate made the 4K resolution that much better."
An anonymous reader writes "This article is an eye opening perspective on another side effect of power generation — water usage: 'More than 40 percent of fresh water used in the United States is withdrawn to cool power plants. Renewable energy generally uses far less water, but there are glaring exceptions, such as geothermal and concentrating solar.' The article also mentions that power plants have to shut down if the incoming water is too warm to cool the plant. 'Also, even though some newer plants might use far less water, they could find that there’s far less water available as water temperatures go up and water flows go down. Another study found that nearly half of 423 U.S. plants were at risk of lower power output during droughts because their intake pipes for water were less than 3 meters below the surface.'"
vikingpower writes "A Dutch newspaper has a digital version of the letter Mr. Opstelten, Secretary of Justice and Security, sent to Dutch Parliament (PDF in Dutch), in which he quietly admits to 56,825 phone taps (a 3% rise in one year) and to 16,676 internet taps in 2012, a 400% rise, or a fivefold increase, in one year. An older report already exposed the Netherlands as one of the biggest wiretappers in the western world. Slate also knew, back in 2006, that Europeans actually love wiretapping and internet tapping. In the Netherlands, a country with a population of only 16 million, the practice has risen to the level of a staggering 1 in 1,000 phones being tapped."
RoccamOccam sends this news from the Associated Press: "A landmark federal study on hydraulic fracturing, or fracking, shows no evidence that chemicals from the natural gas drilling process moved up to contaminate drinking water aquifers at a western Pennsylvania drilling site. After a year of monitoring, the researchers found that the chemical-laced fluids used to free gas trapped deep below the surface stayed thousands of feet below the shallower areas that supply drinking water."
dryriver writes "I am an intermediate-level programmer who works mostly in C# NET. I have a couple of image/video processing algorithms that are highly parallelizable — running them on a GPU instead of a CPU should result in a considerable speedup (anywhere from 10x times to perhaps 30x or 40x times speedup, depending on the quality of the implementation). Now here is my question: What, currently, is the most painless way to start playing with GPU programming? Do I have to learn CUDA/OpenCL — which seems a daunting task to me — or is there a simpler way? Perhaps a Visual Programming Language or 'VPL' that lets you connect boxes/nodes and access the GPU very simply? I should mention that I am on Windows, and that the GPU computing prototypes I want to build should be able to run on Windows. Surely there must a be a 'relatively painless' way out there, with which one can begin to learn how to harness the GPU?"
New submitter LFSim writes "It's not the Turing test just yet, but in one more domain, AI is becoming increasingly competitive with humans. This time around, it's in interplanetary trajectory optimization. From the European Space Agency comes the news that researchers from its Advanced Concepts Team have recently won the Gold 'Humies' award for their use of Evolutionary Algorithms to design a spacecraft's trajectory for exploring the Galilean moons of Jupiter (Io, Europa, Ganymede and Callisto). The problem addressed in the awarded article (PDF) was put forward by NASA/JPL in the latest edition of the Global Trajectory Optimization Competition. The team from ESA was able to automatically evolve a solution that outperforms all the entries submitted to the competition by human experts from across the world. Interestingly, as noted in the presentation to the award's jury (PDF), the team conducted their work on top of open-source tools (PaGMO / PyGMO and PyKEP)."
New submitter ulatekh writes "San Jose State University is suspending a highly touted collaboration with online provider Udacity to offer low-cost, for-credit online courses after finding that more than half of the students failed to pass the classes. 'Preliminary results from a spring pilot project found student pass rates of 20% to 44% in remedial math, college-level algebra and elementary statistics courses. In a somewhat more promising outcome, 83% of students completed the classes.'"
An anonymous reader writes "On Thursday, the board of O-Net gave approval for residents to get access to [full gigabit bandwidth] for the same price that they currently pay for a guaranteed download speed of 100 megabits per second — $57 to $90 a month, depending on whether they have bundled their internet with TV and phone service. ... the town realized that it couldn't attract technology-based businesses and that bandwidth was a challenge even to ordinary businesses. It came up with a plan — it would install a fibre network throughout the town that would connect to the larger inter-community network being built by the government at that time — the Alberta Supernet."
willith writes "The folks at Bezos Expeditions have confirmed that faintly visible serial numbers on one of the large engine components they lifted from three miles below the ocean's surface match the serial number of F-1 engine F-6044, which flew in the center position on Saturn V number SA-506 — Apollo 11. With the 44th anniversary of the first lunar landing coming up tomorrow, the confirmation comes at an auspicious time. The F-1 engine remains to this day the largest single-chamber liquid fueled engine ever produced — although NASA is considering using a newer uprated design designated as the F-1B to help boost future heavy-lift rockets into orbit."
coolnumbr12 writes "When Yahoo purchased Tumblr in May, Tumblr founder David Karp said Tumblr wouldn't be changing, and Yahoo CEO Marissa Mayer said, 'Part of our strategy here is to let Tumblr be Tumblr.' But a new search policy went into effect Thursday that excludes all adult blogs from Google, Bing, Yahoo and other search engines by disabling indexing of anything it tags as 'adult.' The policy effectively makes the content and 10 percent of Tumblr users completely invisible."
New submitter ciotog writes "The town of Deer Trail, Colorado (population approximately 550) will be voting next month on whether to offer licenses for drone hunting. Furthermore, a bounty of $100 for each drone shot down will be offered (upon offering proof that the drone was potentially owned by the U.S. government). Is this just a fun gimmick, or a serious commentary on an increasingly surveillance based society?"
