NVIDIA Launches Tegra K1-Based SHIELD Tablet, Wireless Controller

Slashdot - 46 min 21 sec ago
MojoKid (1002251) writes NVIDIA just officially announced the SHIELD Tablet (powered by their Tegra K1 SoC) and SHIELD wireless controller. As the SHIELD branding implies, the new SHIELD tablet and wireless controller builds upon the previously-released, Android-based SHIELD portable to bring a gaming-oriented tablet to consumers. The SHIELD Tablet and wireless controller are somewhat of mashup of the SHIELD portable and the Tegra Note 7, but featuring updated technology and better build materials. You could think of the SHIELD Tablet and wireless controller as an upgraded SHIELD portable gaming device, with the screen de-coupled from the controller. The device features NVIDIA's Tegra K1 SoC, paired to 2GB of RAM and an 8", full-HD IPS display, with a native resolution of 1920x1200. There are also a pair of 5MP cameras on the SHIELD Tablet (front and rear), 802.11a/b/g/n 2x2 MIMO WiFi configuration, GPS, a 9-axis motion sensor, and Bluetooth 4.0 LE. In addition to the WiFi-only version (which features 16GB of internal storage), NVIDIA has a 32GB version coming with LTE connectivity as well. NVIDIA will begin taking pre-orders for the SHIELD Tablet and wireless controller immediately.

AirMagnet Wi-Fi Security Tool Takes Aim At Drones

Slashdot - 1 hour 26 min ago
alphadogg (971356) writes "In its quest to help enterprises seek out and neutralize all threats to their Wi-Fi networks, AirMagnet is now looking to the skies. In a free software update to its AirMagnet Enterprise product last week, the Wi-Fi security division of Fluke Networks added code specifically crafted to detect the Parrot AR Drone, a popular unmanned aerial vehicle that costs a few hundred dollars and can be controlled using a smartphone or tablet. Drones themselves don't pose any special threat to Wi-Fi networks, and AirMagnet isn't issuing air pistols to its customers to shoot them down. The reason the craft are dangerous is that they can be modified to act as rogue access points and sent into range of a victim's wireless network, potentially breaking into a network to steal data."

MIT' Combines Carbon Foam and Graphite Flakes For Efficient Solar Steam Generation

Slashdot - 2 hours 7 min ago
rtoz (2530056) writes Researchers at MIT have developed a new spongelike material structure which can use 85% of incoming solar energy for converting water into steam. This spongelike structure has a layer of graphite flakes and an underlying carbon foam. This structure has many small pores. It can float on the water, and it will act as an insulator for preventing heat from escaping to the underlying liquid. As sunlight hits the structure, it creates a hotspot in the graphite layer, generating a pressure gradient that draws water up through the carbon foam. As water seeps into the graphite layer, the heat concentrated in the graphite turns the water into steam. This structure works much like a sponge. This new material is able to use 85 percent of incoming solar energy for converting water into steam. It is a significant improvement over recent approaches to solar-powered steam generation. And, this setup loses very little heat in the process, and can produce steam at relatively low solar intensity. i-e if scaled up, this setup will not require complex, costly systems to highly concentrate sunlight.

For Now, UK Online Pirates Will Get 4 Warnings -- And That's It

Slashdot - 2 hours 46 min ago
New submitter Tmackiller writes with an excerpt from VG247.com: The British government has decriminalised online video game, music and movie piracy, scrapping fuller punishment plans after branding them unworkable. Starting in 2015, persistent file-sharers will be sent four warning letters explaining their actions are illegal, but if the notes are ignored no further action will be taken. The scheme, named the Voluntary Copyright Alert Programme (VCAP), is the result of years of talks between ISPs, British politicians and the movie and music industries. The UK's biggest providers – BT, TalkTalk, Virgin and Sky – have all signed up to VCAP, and smaller ISPs are expected to follow suit. VCAP replaces planned anti-piracy measures that included cutting users' internet connections and creating a database of file-sharers. Geoff Taylor, chief executive of music trade body the BPI, said VCAP was about "persuading the persuadable, such as parents who do not know what is going on with their net connection." He added: "VCAP is not about denying access to the internet. It's about changing attitudes and raising awareness so people can make the right choice." Officials will still work to close and stem funding to file-sharing sites, but the news appears to mean that the British authorities have abandoned legal enforcement of online media piracy. Figures recently published by Ofcom said that nearly a quarter of all UK downloads were of pirated content." Tmackiller wants to know "Will this result in more private lawsuits against file sharers by the companies involved?"

The researchers found canvas fingerprinting computer code ... on 5 percent of the top 100,000 websites. Most of the code was on websites that use the AddThis social media sharing tools.
