First 'true' quantum calculation performed An international research group has for the first time demonstrated a quantum algorithm that performs a true calculation, without needing to know the answer before the start. The team's 'phase estimation algorithm', they say, is a central quantum algorithm which achieves an exponential speedup over all classical algorithms. It's a key sub-routine of many other important quantum algorithms, such as Shor's factoring algorithm and quantum simulations. "Before our experiment, there had been several demonstrations of quantum algorithms, however, none of them implemented the quantum algorithm without knowing the answer in advance. "Unlike previous demonstrations, we built a full quantum circuit to implement the phase estimation algorithm without any simplification. The team says its approach can be scaled up to multi-qubit systems, since both the algorithm and the number of qubits can be scaled.
Red light cameras shut down over issue of legality The increasing prevalence of red light cameras and the legal questions that come with them, have caused one city in South Dakota to completely flip the switch on its cameras. In 2006, I.L. Wiedermann received a ticket in the mail for passing through a red light in Sioux Falls. Instead of saying "Oh crap" and just paying the fine like most people, Wiedermann filed a lawsuit against Redflex, the company that operates the cameras. That lawsuit led to a different issue entirely, which came to a head last month. In state court, Judge Kathleen Caldwell said that the entire process set up by Sioux Falls was illegal. Caldwell said that the city was issuing civil tickets to motorists caught passing a red light, which is a criminal offense. "In light of that ruling, it was decided to suspend the system for now," said Sioux Falls Police Chief Doug Barthel. In the mean time, the contract between the city and Redflex has been suspended.
Metblogs Welcome Back BYTE BYTE -- It's time! BYTE, the most venerated tech media source of all time, is back! Authoritative, trusted and deeply technical, BYTE set the bar for tech coverage for decades. And I'm thrilled and so pleased to announce its return today, right in the middle of summer 2011. It's been too long! Originally launched in 1975, BYTE ushered in the personal computer revolution. Since BYTE closed down in 1998, there has been an aching chasm in tech journalism. BYTE is here to focus on the technology you care most about. BYTE pulls no punches -- we'll dig deep to make sure you know exactly what you need to know to get the most out of your tech, to find out what's worth buying and what to avoid at all cost. I want to give a special thanks original BYTE folk who join us on its return. To top it off, we have as our senior technologist Jerry Pournelle, whose Computing from Chaos Manor column was the first thing so many readers turned to in the decade. BYTE is back. Who is teamBYTE?

Time to upgrade your TI-89, Texas Instruments introduces the Bla The dev-centric TI Blaze tablet There was a time when the closest thing to a tablet computer was the Texas Instruments calculators. Personally, we still remember the time we finally got Golf to start working on our TI-83. Truly those were magical times. But now it’s time to turn in the most expensive thing in your bookbag — Texas Instruments has upgraded to the new Blaze tablet. The Blaze uses a development platform developed by Texas Instruments called OMAP 4 which is tailored to mobile hardware and features applications processors and low energy consumption. The Texas Instruments Blaze tablet runs off a OMAP4430 1GHz processor, has a 10.4-inch 1024 x 768 resolution multitouch screen, 1 GB of DDR2 RAM, 32GB of storage and features HDMI, two USB host ports, USB OTG, SD Card, SIM and LED backlit OS buttons. So after digesting all those specs do you still want one? : Slashgear
sbdc | changing the world, one pixel at a time Averatec D1200 25.5-Inch All-In-One PC Review - ComputerShopper. Share This Review: Share on facebook Share on twitter Share on email Share on google More Sharing Services At about 3 inches thick, the Averatec D1200's body is pleasingly svelte for an all-in-one. Traditionally, the trade-off for buying an all-in-one desktop like the Apple iMac or our recent favorite, the Lenovo ThinkCentre A600, is that it typically costs hundreds of dollars more than comparable hardware in a typical tower with a separate LCD. In fact, we priced the parts from our favorite online outlet, and found it almost impossible to build a desktop system with the D1200's specs (including a 25.5-inch, 1,920x1,200 monitor, 2.5GHz Pentium Dual Core E5200 processor, 4GB of RAM, a digital TV tuner with remote, and a 320GB, 7,200rpm hard drive) for under $900. We prefer the design of Lenovo's ThinkCentre A600 to the Averatec D1200's comparatively boring piano-black look. The other all-in-one PC to get a fair amount of press lately is the Dell Studio One 19.
Unlock Your Front Door Geek-Style This has to be the geekiest thing I’ve ever written about. I’m a geek by any standard, but even this is a bit over the edge for me. But, the geek in me thinks it is so uber-cool that I can’t resist writing about it. Get ready to meet the gadget that will trump all other gadgets. Steve Hoefer is just a regular guy who built something cool with some spare parts he found in his lab. Long story short, because of this he has received thousands of hits to his blog and a half million hits on YouTube in the past ten days. What’s all the fuss about? How does it work? I would have loved one of these for my play house in the backyard when I was six. Of course, the downfall to having a lock system like this is that if you live in an apartment building, your nosey neighbors could memorize the knock pattern. I’ve read where some people have suggested using a timestamp or a series of one time knocks to get around this, but I know, to ponder that is to jump off the deep end of geekness.
Lenovo IdeaCentre B500 (08873AU) Review Share This Review: Share on facebook Share on twitter Share on email Share on google More Sharing Services Back in October of 2009, when we reviewed the Gateway One ZX6810-01, we tagged it as the most powerful all-in-one (AIO) PC we'd ever seen. Competing models have either been significantly more expensive, like the $1,800 Sony VAIO L Series VPCL117FX/T, or hampered by a component-based Achilles’ heel, like the recently reviewed Gateway One ZX6900-01e, which is saddled with integrated Intel graphics. Aesthetically, the IdeaCentre B500 makes a respectable attempt at continuing the IdeaCentre line’s tradition of combining handsome good looks with crowd-pleasing features. The display’s bezel is made of glossy black plastic, and the base that props it up is silver and shiny. The system's orange highlights are hidden from plain sight in the rear, but are in plain sight on the peripherals. We welcome the B500's wireless peripherals, but could live without the orange accents.
Social Media Today | 2010: Markets Will Do The Unusual At the end of every year it seems everyone has a prediction of what is to come next year. Trends can lead one to predictive analysis of likely events on the horizon with some being relevant to planning and some only relative to what your actually planning to do next year. With each year that passes one thing is certain, things will change. Whether for business or personal one change is certain, you have to learn to do more with less. What Is Unusual? Unusual means doing things differently than you have in the past. Whether personal or professional thinking about making progress in the coming year means we need to put past, present and future changes into context that relate to our own plans. What is unusual about communications and relationships? Markets are moving because the market behavior has changed. Below are some trends provided by trendwatching.com that reflect the changes happening around us and our businesses. Urban culture is the culture. Highlight any portion you want: Connect:
