Frequency Deviations In Continental Europe Are Causing Electric Clocks To Run Behind By 5 Minutes (entsoe.eu) 251

elgatozorbas shares a short note from the European Network of Transmission System Operators for Electricity (ENTSO-E): Apparently the Continental European Power System has been off since mid-January, causing some clocks to run behind by 5 minutes. How common are these mains-frequency synchronized clocks anyway, and why are they built that way? "The power deviations have led to a slight drop in the electric frequency," reports ENTSO-E. "This in turn has also affected those electric clocks that are steered by the frequency of the power system and not by a quartz crystal... All actions are taken by the transmission system operators (TSOs) of Continental Europe and by ENTSO-E to resolve the situation."

Google Unveils 72-Qubit Quantum Computer With Low Error Rates (tomshardware.com) 76

An anonymous reader quotes a report from Tom's Hardware: Google announced a 72-qubit universal quantum computer that promises the same low error rates the company saw in its first 9-qubit quantum computer. Google believes that this quantum computer, called Bristlecone, will be able to bring us to an age of quantum supremacy. In a recent announcement, Google said: "If a quantum processor can be operated with low enough error, it would be able to outperform a classical supercomputer on a well-defined computer science problem, an achievement known as quantum supremacy. These random circuits must be large in both number of qubits as well as computational length (depth). Although no one has achieved this goal yet, we calculate quantum supremacy can be comfortably demonstrated with 49 qubits, a circuit depth exceeding 40, and a two-qubit error below 0.5%. We believe the experimental demonstration of a quantum processor outperforming a supercomputer would be a watershed moment for our field, and remains one of our key objectives."

According to Google, a minimum error rate for quantum computers needs to be in the range of less than 1%, coupled with close to 100 qubits. Google seems to have achieved this so far with 72-qubit Bristlecone and its 1% error rate for readout, 0.1% for single-qubit gates, and 0.6% for two-qubit gates. Quantum computers will begin to become highly useful in solving real-world problems when we can achieve error rates of 0.1-1% coupled with hundreds of thousand to millions of qubits. According to Google, an ideal quantum computer would have at least hundreds of millions of qubits and an error rate lower than 0.01%. That may take several decades to achieve, even if we assume a "Moore's Law" of some kind for quantum computers (which so far seems to exist, seeing the progress of both Google and IBM in the past few years, as well as D-Wave).

Oculus Rift Is Now the Most Popular VR Headset On Steam (venturebeat.com) 60

The Oculus Rift has overtaken the HTC Vive on the monthly Steam hardware survey for the first time since the launch of both headsets in early 2016. VentureBeat reports: The survey is entirely optional and scans a user's PC for various hardware components, including any VR headsets that may be connected. After a few months of catching up to Vive, the Rift was neck-and-neck with its rival in January's survey with 0.9 percent between the two. However, February saw Oculus step past HTC; Rift took 47.31 percent of the total hardware use, and Vive fell to 45.38 percent, leaving just under 2 percent between them. It's still a tight race, then, but this is the first time Rift has managed to surpass Vive. Again, this is in no way confirmation that the Oculus Rift has sold more units than the HTC Vive, as neither headset has had official sales figures released, but it's the best shot we've got at gauging the market share right now. Rift also took the "Most Popular Headset" space in Steam's individual listings for the second time ever.

Google Fiber Is a Faint Echo of the Disruption We Were Promised (vice.com) 173

An anonymous reader quotes a report from Motherboard: Some eight years on and Google Fiber's ambitions are just a pale echo of the disruptive potential originally proclaimed by the company. While Google Fiber did make some impressive early headway in cities like Austin, the company ran into numerous deployment headaches. Fearing competition, incumbent ISPs like AT&T and Comcast began a concerted effort to block the company's access to essential utility poles, even going so far as to file lawsuits against cities like Nashville that tried to expedite the process. Even in launched markets, customer uptake wasn't quite what executives were expecting. Estimates peg Google Fiber TV subscribers at fewer than 100,000, thanks in large part to the cord cutting mindset embraced by early adopters. Broadband subscriber tallies (estimated as at least 500,000) were notably better, but still off from early company projections. Even without anti-competitive roadblocks, progress was slow. Digging up city streets and burying fiber was already a time-consuming and expensive process. And while Google has tried to accelerate these deployments via something called "microtrenching" (machines that bury fiber an inch below roadways), broadband deployment remains a rough business. It's a business made all the rougher by state and local regulators and lawmakers who've been in the pockets of entrenched providers like Comcast for the better part of a generation.

Levi Strauss Replaces Human Sanding With Automated Lasers (bloomberg.com) 237

_Sharp'r_ writes: Stressing jeans used to require 300 to 400 workers with sandpaper all day. Now Levi Strauss does a better job by shooting their new jeans with computer-guided lasers in intricate patterns generated in CAD systems. Along the way, they save water and "will cut the number of chemicals it uses to produce jeans from 1,000 to a few dozen," reports Bloomberg.

Thieves Steal 600 Powerful Bitcoin-Mining Computers In Iceland (apnews.com) 88

The Associated Press reports of a Bitcoin heist in Iceland where thieves stole some 600 computers used to "mine" bitcoin and other virtual currencies. "Some 11 people were arrested, including a security guard, in what Icelandic media have dubbed the 'Big Bitcoin Heist,'" reports the Associated Press. From the report: The powerful computers, which have not yet been found, are worth almost $2 million. But if the stolen equipment is used for its original purpose -- to create new bitcoins -- the thieves could turn a massive profit in an untraceable currency without ever selling the items. Three of four burglaries took place in December and a fourth took place in January, but authorities did not make the news public earlier in hopes of tracking down the thieves. Police tracking the stolen computers are monitoring electric consumption across the country in hopes the thieves will show their hand, according to an industry source who spoke on condition of anonymity because he is not allowed to speak to the media. Unusually high energy usage might reveal the whereabouts of the illegal bitcoin mine. Authorities this week called on local internet providers, electricians and storage space units to report any unusual requests for power.
