Australian Student Balloon Rises 100,000 Feet, With a Digital Camera
hype7 writes "An Australian student at Deakin University had a fascinating idea for a final project — to send a balloon up 100,000ft (~30,000 metres) into the stratosphere with a digital camera attached. The university was supportive, and the project took shape. Although there were some serious hitches along the way, the project was successful, and he managed to retrieve the balloon — with the pictures. What's really amazing is that the total cost was so low; the most expensive part was buying the helium gas for approximately AUD$250 (~USD$200)."Read more of this story at Slashdot.
Cisco, Motorola, and Other Companies Take Aim At Net Neutrality Rules
angry tapir writes "FCC Chairman Julius Genachowski announced last month that he would seek to develop formal rules prohibiting Internet service providers from selectively blocking or slowing Web content and applications. However, 44 companies — including Cisco Systems, Alcatel-Lucent, Corning, Ericsson, Motorola and Nokia — have sent a letter to the FCC saying new regulations could hinder the development of the Internet. A group of 18 Republican US senators have also sent a letter to Genachowski raising concerns about net neutrality regulations."Read more of this story at Slashdot.
Affordably Aggregating ISP Connections?
An anonymous reader writes "Has anyone setup a system to aggregate multiple ISP connections to form a high bandwidth site-to-site link? Load Sharing SCTP looked interesting, but it doesn't look like it has been widely adopted. Multi-Link PPP appears to be more widely supported for clients, but I can't find any good guides for setting up both sides of the connection for a site-to-site link. The hardware solutions I've found are expensive for a small business. Does anyone have experience using hardware solutions from Mushroom Networks (Virtual Leased Line, p2 of this document), Ecessa (site-to-Site Channel Bonding), or others?"Read more of this story at Slashdot.
Scientists Discover How DNA Is Folded Within the Nucleus
mikael writes "Sciencedaily.com is reporting that scientists have discovered how DNA is folded within the nucleus of a cell such that active genes remain accessible without becoming tangled. The first observation is that genes are actually stored in two locations. The first location acts as a cache where all active genes are kept. The second location is a denser storage area where inactive genes are kept. The second observation is that all genes are stored as fractal globules, which allows genes that are used together to be adjacent to each other when folded, even though they may be far apart when unfolded."Read more of this story at Slashdot.
Sonar Software Detects Laptop User Presence
Steve Tarzia writes "A research group at Northwestern University and University of Michigan has released open-source display power-management software that uses a new user presence detection technique. The goal is to shut off the display immediately when the user leaves the computer rather than using slow and error-prone mouse/keyboard activity timeouts. Surprisingly, the mic and speakers of many laptop computers are sensitive to ultrasonic frequencies. Those frequencies can be used to silently probe the laptop's physical environment. This software is based on research published at the UbiComp2009 conference. A Windows binary and source code for Windows and Linux are available for download."Read more of this story at Slashdot.
Toyota Claims Woman "Opted In" To Faux Email Stalking
An anonymous reader writes "ABC News is reporting that a California woman is suing Toyota for $10 million for sending her email that appeared to be from a criminal stalker. The woman claims the emails terrified her to the point that she suffered sleeplessness, poor work performance, etc. Toyota says the ruse was part of a marketing campaign for the Toyota Matrix. A Toyota spokesman says they are not liable for the woman's distress, because 'The person who made this claim specifically opted in, granting her permission to receive campaign emails and other communications from Toyota.'"Read more of this story at Slashdot.
China Strangles Tor Ahead of National Day
TechReviewAl writes "Technology Review reports that the Chinese government has for the first time targeted the Tor anonymity network. In the run-up to China's National Day celebrations, the government started targeting the sites used to distribute Tor addresses and the number of users inside China dropped from tens of thousands to near zero. The move is part of a broader trend that involves governments launching censorship crackdowns around key dates. The good news is that many Tor users quickly found a way around the attack, distributing 'bridge' addresses via IM and Twitter."Read more of this story at Slashdot.
MS Says All Sidekick Data Recovered, But Damage Done
nandemoari writes "T-Mobile is taking a huge financial hit in the fallout over the Sidekick data loss. But Microsoft, which bears at least part of the responsibility for the mistake, is paying the price with its reputation. As reported earlier this week, the phone network had to admit that some users' data had been permanently lost due to a problem with a server run by Microsoft-owned company Danger. The handset works by storing data such as contacts and appointments on a remote computer rather than on the phone itself. BBC news reports today that Microsoft has in fact recovered all data, but a minority are still affected (out of 1 million subscribers). Amidst this, Microsoft appears not to have suffered any financial damage. However, it seems certain that its relationship with T-Mobile will have taken a major knock. The software giant is also the target of some very bad publicity as critics question how on earth it failed to put in place adequate back-ups of the data. That could seriously damage the potential success of the firm's other 'cloud computing' plans, such as web-only editions of Office."Read more of this story at Slashdot.
Scientists Use Quake 2 To Study the Brains of Mice
An anonymous reader writes "In this week's issue of Nature, scientists from Princeton University trained mice to navigate around a virtual environment using a setup that resembles a combination of a giant trackball and a mini-iMax theater displaying a virtual world rendered using a modified version of the Quake 2 open source game engine. (Here's the academic paper, subscription required.) They hold the mouse's head still atop a giant trackball, which the mouse turns by running. The scientists use the rotations to move the mouse around in the virtual environment, and when he reaches certain places, he gets a reward. Because they are able to hold the head still, they can stick microscopic glass electrodes into individual neurons in the hippocampus of this mouse as it 'navigates.' They find the neural activity that resembles activity during real life navigation, and learned new things about the inputs and computations that are going on inside these neurons, which weren't known before. No word as of yet whether the scientists plan on giving the mice control of the gun. Wonder whether John Carmack ever envisioned this when he opened up the Quake code?"Read more of this story at Slashdot.
Wi-Fi Direct Overlaps Bluetooth Territory For Connecting Devices
Reber Is Reber writes "The Wi-Fi Alliance announced a new wireless networking specification which will enable devices to establish simple peer-to-peer wireless connections without the need for a wireless router or hotspot. Wi-Fi Direct has a wide array of potential uses, many of which encroach on Bluetooth territory and threaten to make the competing wireless protocol obsolete. 'Wi-Fi Direct represents a leap forward for our industry. Wi-Fi users worldwide will benefit from a single-technology solution to transfer content and share applications quickly and easily among devices, even when a Wi-Fi access point isn't available,' said Wi-Fi Alliance executive director Edgar Figueroa. 'The impact is that Wi-Fi will become even more pervasive and useful for consumers and across the enterprise.' Ad hoc wireless networking has always been more complex and cumbersome than it is worth, and it maxes out at 11 mbps. Wi-Fi Direct will connect at existing Wi-Fi speeds-- up to 250 mbps. Wi-Fi Direct devices will also be able to broadcast their availability and seek out other Wi-Fi Direct devices. Wi-Fi Direct overlaps into Bluetooth territory. Bluetooth is a virtually ubiquitous technology used for wireless connection of devices like headphones, mice, or the ever-popular Bluetooth earpiece sticking out of everyone's head. Bluetooth uses less power, but also has a much shorter range and slower transfer speeds. Wi-Fi Direct can enable the same device connectivity as Bluetooth, but at ranges and speeds equivalent to what users experience with existing Wi-Fi connections."Read more of this story at Slashdot.
Doubts Raised About Legal Soundness of GPL2
svonkie writes "Two prominent IP lawyers have warned that the all-pervasive General Public License version 2 (GPLv2) is legally unsound. They claim GPLv3 and AGPLv3 are much better suited for the realities of modern open source software. 'If you go back in time to when GPLv2 was written, I don't think people were aware of just how ubiquitous this license would become and how closely scrutinized it would be,' said Mark Radcliffe, partner at the firm DLA Piper and general counsel for the Open Source Initiative (OSI). 'At that time, open source was not something as broadly used as it is now.' Radcliffe was joined by Karen Copenhaver, partner at Choate Hall & Stewart and counsel for the Linux Foundation, for a GPL web conference hosted by the license-sniffing firm Black Duck software"Read more of this story at Slashdot.
12M Digit Prime Number Sets Record, Nets $100,000
coondoggie writes "A 12-million-digit prime number, the largest such number ever discovered, has landed a voluntary math research group a $100,000 prize from the Electronic Frontier Foundation (EFF). The number, known as a Mersenne prime, is the 45th known Mersenne prime, written shorthand as 2 to the power of 43,112,609, minus 1 . A Mersenne number is a positive integer that is one less than a power of two, the group stated. The computing project called the Great Internet Mersenne Prime Search (GIMPS) made the discovery on a computer at the University of California, Los Angeles (UCLA) Mathematics Department."Read more of this story at Slashdot.
Hands-On Look At the BlackBerry Storm 2
Barence writes "PC Pro has had time to play with the new BlackBerry Storm 2, and came away impressed. The new touch system garners the most praise, doing away with the mechanical click screen of the original Storm — the new screen gives a kind of localised haptic feedback which 'feels just like clicking a button.' The phone, announced today, also includes Wi-Fi, BlackBerry OS 5, and increased storage, so it's looking an enticing prospect. After the disappointment of the Palm Pre, could this be the smartphone to beat?"Read more of this story at Slashdot.
UK Copyright Group Tells Cinemas to Ban Laptops
Sockatume writes "Cinema chain Cineworld now has a policy banning anyone from carrying a laptop into a theatre, even if it is not used. The management claims that this is an anti-piracy move on the advice of the Federation Against Copyright Theft, the much-mocked source of all kinds of dubious anti-piracy statements. When it was pointed out that the laptop had no camera, the management made a temporary exception. For customers, the message is clear: leave your laptop in the car. For pirates, the message is clear: there is more money to be made slinking around cinema car parks looking for laptop bags."Read more of this story at Slashdot.
Should I Publish Or Patent?
BorgeStrand writes 'Patenting is an expensive process, even coming up with some sort of proof that your idea is unique (and thereby try to attract financing) may be prohibitive for the lone inventor. So what do you folks out there do when you come up with a good idea but don't have the means to patent it or market it to someone who will pay for the patenting process? And how much sense does it really make for the lone inventor to patent something? Would it make more sense to publish the whole idea, and make it (and my inventive brainpower) up for grabs? If my ideas are indeed valuable, what is the best way to gain anything from them without investing too much financially? What is your experience?'Read more of this story at Slashdot.
