Qualcomm Ships Dual-Core Snapdragon Chipsets 168

rrossman2 writes "Qualcomm has issued a press release revealing it has started shipping new dual-core Snapdragon chipsets. These chipsets run each core at up to 1.2GHz, include a GPU that supports 2D/3D acceleration engines for Open GLES 2.0 and Open VG 1.1, 1080p video encode/decode, dedicated low-power audio engine, integrated low-power GPS, and support for 24-bit WXGA 1280x800 resolution displays. These chipsets come in two variants, the MSM8260 for HSPA+ and the MSM8660 for multi-mode HSPA+/CDMA2000 1xEV-DO Rev B. The press release also lists QSD8672 as a third-gen chipset like the two mentioned, but doesn't go into any detail of what its role is. With this announcement of shipping chipsets, how long until HTC makes a super smartphone?"

Quantifying, and Dealing With, the Deepwater Spill 343

Gooseygoose writes with a link to this analysis by Boston University professor Cutler Cleveland. "Some reports in the media attempt to downplay the significance of the release of oil from the Deepwater Horizon accident by arguing that natural oil seeps release large volumes of oil to the ocean, so why worry? Let's look at the numbers." Read on for a few more stories on the topic of the Deepwater Horizon spill.

New Radar Device Helps Blind People 'See' 73

greenrainbow writes "Students in Israel at the Ben-Gurion University of the Negev have developed new technology that allows blind people to 'see' objects around them through a simple radar system. The device consists of a computer, two video cameras, and a scanning light source; it audibly alerts the individual of objects that are in close proximity. The system scans surrounding objects and their distance from two points, much like the human eyes. Unlike current sensor canes, this new light scanning device is a hands-free system that can sense objects on the ground, overhead, and in the periphery."

New Gadget Tells You When To Take a Break Screenshot-sm 50

Kilrah_il writes "An Israeli company developed a gadget that measures your blood pressure and tells you when you are stressed and need to take a break from your computer. 'The user grasps two sensors shaped like computer mouses to measure the electric activity of the heart in minute detail. Software then combines the measurements with prerecorded personal details such as age and sex to calculate various indicators for stress and mood.' Looks like a must-have accessory for Slashdotters everywhere."

AMD's Fusion Processor Combines CPU and GPU 240

ElectricSteve writes "At Computex 2010 AMD gave the first public demonstration of its Fusion processor, which combines the Central Processing Unit (CPU) and Graphics Processing Unit (GPU) on a single chip. The AMD Fusion family of Accelerated Processing Units not only adds another acronym to the computer lexicon, but ushers is what AMD says is a significant shift in processor architecture and capabilities. Many of the improvements stem from eliminating the chip-to-chip linkage that adds latency to memory operations and consumes power — moving electrons across a chip takes less energy than moving these same electrons between two chips. The co-location of all key elements on one chip also allows a holistic approach to power management of the APU. Various parts of the chip can be powered up or down depending on workloads."

Jumbo Dual-Screen "Kno" Tablet Debuts At D8 106

itwbennett writes "The Microsoft Courier may be a dead project, but that doesn't mean you can't still have a dual-touchscreen e-reader. And a super-sized one at that, says blogger Peter Smith. The Kno, which debuted at All Things Digital's D8 conference yesterday has 'two 14.1-inch (1440 x 900) capacitive touch screens. Each screen has its own battery, giving the Kno 8-hours of battery life, but a hefty weight of 5.5 lbs. ... If Kno (the company) has its way, students will be carrying around a Kno (the device) rather than a stack of textbooks. That's the reason for the huge screens; most textbook pages can be shown 'full size' on a 14-inch screen.' Engadget, who got some hands-on time with the device, says 'the entire experience is essentially a WebKit instance.' Price is still up in the air but Ina Fried at CNET says the company is aiming for a price well under $1,000."

Traffic-Flow Algorithm Can Reduce Fuel Consumption 328

thecarchik writes "New projects from German automakers Audi and BMW promise to ease congestion simply by looking at traffic signals and driving style, in an effort to smooth the flow of traffic. Through a test course in Munich, vehicles were able to post phenomenal fuel efficiency gains simply by adjusting the timing of traffic lights depending on traffic volume — to whatever speed provides a so-called 'green wave' of four or more synchronized signals."

Mobile Phones vs. Supercomputers of the Past 247

An anonymous reader writes "The recently published Top 500 list of the world's fastest supercomputers is based on the Linpack benchmark developed decades ago by Jack Dongarra. This same test has been ported to Android mobile phones, which means that we can compare the performance of our phones against that of the supercomputers of the past. For example, a tweaked Motorola Droid can hit 52 Mflop/s, which is more than 15 times faster than the CPUs used in the 1979 Cray-1." But even today's most powerful cellphones don't come with an integrated bench.

Part-Human, Part-Machine Transistor Devised 77

asukasoryu writes "Man and machine can now be linked more intimately than ever, according to a new article in the journal ACS Nano Letters. Scientists have embedded a nano-sized transistor inside a cell-like membrane and powered it using the cell's own fuel. To create the implanted circuit, the UC scientists combined a carbon nanotube transistor, lipid bilayer coating, ion pump, and ATP. The ion pump changes the electrical charge inside the cell, which then changes the electrical charge going through the transistor, which the scientists could measure and monitor."

Visualizing System Latency 68

ChelleChelle writes "Latency has a direct impact on performance — thus, in order to identify performance issues it is absolutely essential to understand latency. With the introduction of DTrace it is now possible to measure latency at arbitrary points; the problem, however, is how to visually present this data in an effective manner. Toward this end, heat maps can be a powerful tool. When I/O latency is presented as a visual heat map, some intriguing and beautiful patterns can emerge. These patterns provide insight into how a system is actually performing and what kinds of latency end-user applications experience."

Software Describes Surveillance Footage In AI-Generated Text 132

holy_calamity writes "A computer vision research group at UCLA has put together a system that watches surveillance footage and generates a text description of the events in real time. It only works on traffic cameras for now but demonstrates how sophisticated computer vision is becoming. Interestingly, the system was built thanks to a database of millions of human-labeled images put together by Chinese workers."

Hands-On Demo Shows Asus E-Reader Tablet In Action 108

MojoKid writes "Mobile computing is making its mark at Computex 2010, with tablet PCs and e-readers of all sorts coming out for the first time as rivals to Apple's iPad. After announcing its Eee Pad tablet PC, Asus offered some hands-on time with its new e-Reader/e-Writer, designed for students and mobile business professionals. The little slate's features include 10-hour battery life, 2,450 dpi resolution touch screen, pen writing and input controls, 2MP camera, USB port, and a MicroSD slot. In addition, Asus also has strong ties with Amazon, so it wouldn't be a reach to see some sort of partnership between Asus and Amazon with the Kindle bookstore as a content provider."

Hybrid Seagate Hard Drive Has Performance Issues 67

EconolineCrush writes "The launch of Seagate's Momentus XT hard drive was discussed here last week, and for good reason. While not the first hybrid hard drive on the market, the XT is the only one that sheds the Windows ReadyDrive scheme for an OS-independent approach Seagate calls Adaptive Memory. While early coverage of the XT was largely positive, more detailed analysis reveals a number of performance issues, including poor sequential read throughput and an apparent problem with command queuing. In a number of tests, the XT is actually slower than Seagate's year-old Momentus 7200.4, a drive that costs $40 less."

iRobot Demonstrates New Weaponized Robot 188

An anonymous reader writes "According to this IEEE story, iRobot and the US military have released video showing a weaponized version of iRobot's Warrior robot. In the video, the Warrior is seen firing a weapon system called the APOBS (Anti-Personnel Obstacle Breaching System), a grenade-filled line propelled by a rocket and stabilized by a drogue parachute. This system is used to clear minefields and obstructed roads. The video shows soldiers deploying a Warrior with the APOBS mounted on its back. The robot fires the device, which lands along a dirt road, exploding after a few seconds. A voice is then heard, 'Road clear; proceed forward.'"

Hitachi-LG Debuts HyDrive, Optical Drive With SSD 88

MojoKid writes "A fairly new Hitachi-LG joint venture announced the world's first hybrid optical drive, called the HyDrive. This unique device is a notebook optical drive with an SSD built in. When you slide it into your machine and it connects via SATA 3Gbps, your computer recognizes not only a DVD burner / Blu-ray drive, but also a 32GB or 64GB SSD. This configuration allows you to have an SSD without taking up the single 2.5-inch storage slot within your laptop, so you could then have an optical drive, an SSD, and the standard hard drive as well. There are also a few nice tricks you can play in caching with the on-board SSD. Error-correction techniques can be employed that allowed a damaged disk to be be playable." The HyDrive will ship to OEMs in August; a smaller version usable in netbooks is planned for 2011. The Register has some more technical details and specs.

New Sony OLED Display Can Roll Into Cylinder 73

Anarki2004 writes "Sony recently debuted its latest in OLED technology: a 4.1-inch screen that's only 80 microns thick. The super-flexible display can roll up into a cylinder just 4mm in diameter while still showing moving images at 432×240 resolution. Instead of brittle integrated circuit chips, the screen has an on-panel gate-driven circuit — a world first, according to Sony. That innovation would allow everything but the power supply to roll and flex in applications."

UK Students Build Electric Car With 248-Mile Range 192

da_how writes "A group of students and graduates at Imperial College London have built an electric car with a massive range — 248+ miles on a charge at 'reasonable' highway speeds (60 mph). They did this by filling the car to the absolute max with as many lithium iron phosphate batteries as possible — 56 kWh — and designing a very efficient direct drive powertrain, about 90% batteries-to-wheels at highway speeds. The choice of vehicle is an interesting one: it's a converted Radical SR8 — a track racing car with a speed record on the Nurburgring. Not an obvious contender for an endurance vehicle (no windscreen either!) — but then they claim it's lightweight to start with, being constructed of steel space frame and glass fiber. Also, Radical is based in the UK and provided some help and sponsorship. The students plan to drive their 'SRZero' 15,000 miles down the Pan American Highway, beginning July 8 in Prudhoe Bay, Alaska, and ending up in Tierra Del Fuego three month later. That's about 60 charges."

When Mistakes Improve Performance 222

jd and other readers pointed out BBC coverage of research into "stochastic" CPUs that allow communication errors in order to reap benefits in performance and power usage. "Professor Rakesh Kumar at the University of Illinois has produced research showing that allowing communication errors between microprocessor components and then making the software more robust will actually result in chips that are faster and yet require less power. His argument is that at the current scale, errors in transmission occur anyway and that the efforts of chip manufacturers to hide these to create the illusion of perfect reliability simply introduces a lot of unnecessary expense, demands excessive power, and deoptimises the design. He favors a new architecture, that he calls the 'stochastic processor,' which is designed to handle data corruption and error recovery gracefully. He believes he has shown such a design would work and that it would permit Moore's Law to continue to operate into the foreseeable future. However, this is not the first time someone has tried to fundamentally revolutionize the CPU. The Transputer, the AMULET, the FM8501, the iWARP, and the Crusoe were all supposed to be game-changers but died cold, lonely deaths instead — and those were far closer to design philosophies programmers are currently familiar with. Modern software simply isn't written with the level of reliability the stochastic processor requires (and many software packages are too big and too complex to port), and the volume of available software frequently makes or breaks new designs. Will this be 'interesting but dead-end' research, or will Professor Kumar pull off a CPU architectural revolution really not seen since the microprocessor was designed?"

Japan Plans Moon Base Built By Robots For Robots 253

An anonymous reader writes "The Japanese space agency, JAXA, has plans to build a base on the Moon by 2020. Not for humans, but for robots — and built by robots, too. A panel authorized by Japan's prime minister has drawn up preliminary plans for how humanoid and rover robots will begin surveying the moon by 2015, and then begin construction of a base near the south pole of the moon. The robots and the base will run on solar power, with total costs about $2.2 billion USD, according to the panel chaired by Waseda University President Katsuhiko Shirai. 'As currently envisioned, the robots that will land on the lunar surface in 2015 will be 660-pound behemoths equipped with rolling tank-like treads, solar panels, seismographs, high-def cameras, and a smattering of scientific instruments. They'll also have human-like arms for collecting rock samples that will be returned to Earth via rocket.'"
