Submission + - Intel Unveils 'Breakthrough' 49 Qubit Quantum Computer (extremetech.com) 1

cold fjord writes: Extremetech reports, "At CES 2018 this week, Intel’s CEO . . .declared the company’s new 49-qubit quantum computer represented a step towards “quantum supremacy.” A 49 qubit system is a major advance for Intel, which just demonstrated a 17-qubit system two months ago. Intel’s working with the Netherlands-based Qutech on this project, and expanding the number of qubits is key to creating quantum computers that can deliver real-world results. . . . “Qubits are tremendously fragile: Any noise or unintended observation of them can cause data loss. This fragility requires them to operate at about 20 millikelvin – 250 times colder than deep space.” This is also why we won’t be seeing quantum computers in anyone’s house at any point."

Submission + - ReactOS 0.4.7 Released (reactos.org)

jeditobe writes: OS News reports that the latest version of ReactOS has been released:
"ReactOS 0.4.7 has been released, and it contains a ton of fixes, improvements, and new features. Judging by the screenshots, ReactOS 0.4.7 can run Opera, Firefox, and Mozilla all at once, which is good news for those among us who want to use ReactOS on a more daily basis. There's also a new application manager which, as the name implies, makes it easier to install and uninstall applications, similar to how package managers on Linux work. On a lower level, ReactOS can now deal with Ext2, Ext3, Ext4, BtrFS, ReiserFS, FFS, and NFS partitions."
General notes, tests, and changelog for the release can be found at their respective links. A less technical community changelog for ReactOS 0.4.7 is also available. ISO images are ready at the ReactOS Download page.

Submission + - 24 Cores and The Mouse Won't Move: Engineer Diagnoses Win10 Bug

ewhac writes: Bruce Dawson recently posted a deep-dive into an annoyance that Windows 10 was inflicting on him — namely, every time he built Chrome, his extremely beefy 24-core (48-thread) rig would begin stuttering, with the mouse frequently becoming stuck for a little over one second. This would be unsurprising if all cores were pegged at 100%, but overall CPU usage was barely hitting 50%. So he started digging out the debugging tools and doing performance traces on Windows itself. He eventually discovered that the function NtGdiCloseProcess(), responsible for Windows process exit and teardown, appears to serialize through a single lock, each pass through taking about 200S each. So if you have a job that creates and destroys a lot of processes very quickly (like building a large application such as Chrome), you're going to get hit in the face with this. Moreover, the problem gets worse the more cores you have. The issue apparently doesn't exist in Windows 7. Microsoft has been informed of the issue and they are allegedly investigating.

Submission + - Aaron Swartz eBook Watermarking Has Been Cracked 2

jenningsthecat writes: From Hackaday comes news that the collected writings of Aaron Swartz, released as a watermarked eBook by publishing company Verso Books, has had its watermarking scheme cracked by The Institute for Biblio-Immunology, who also published a guide for removing the BooXtream watermarks.

The writings of Aaron Swartz, with DRM applied? Oh, the irony. Still, at least the DRM employed doesn't restrict a user from reading the book on any and all capable devices, so it's not a very intrusive form of DRM. But I somehow doubt that Mr. Swartz would take any comfort from that, and I bet the fact that companies are profiting from DRM'd copies of his writing has him spinning in his grave. I wonder if his family will have anything to say about this...

Real-Life Frogger Ends In Hospital Visit 314

BigSes writes "A 23-year old man has been hospitalized after police in South Carolina say he was hit by an SUV while playing a real-life version of the video game Frogger. Authorities said the 23-year-old man was taken to a hospital in Anderson after he was struck Monday evening. Before he was hit, police say the man had been discussing the game with his friends. Chief Jimmy Dixon says the man yelled 'go' and darted into oncoming traffic in the four-lane highway. Has it come time to ban some of the classics before someone else goes out and breaks a few bricks with their heads after eating a large mushroom?"

Tales From the Tech Trenches 99

GMGruman writes "Anyone in IT has a story or two involving stupid users, crazy co-workers, kludgy technology, and airhead managers. Lisa Blackwelder has collected top tales of the tech trenches, covering user antics, office politics, and unusual technical challenges that IT pros faced (usually) with aplomb, insight, and savvy."

USAF Unveils Supercomputer Made of 1,760 PS3s 163

digitaldc writes with this excerpt from Gamasutra: "The Air Force Research Laboratory (AFRL) has connected 1,760 PlayStation 3 systems together to create what the organization is calling the fastest interactive computer in the entire Defense Department. The Condor Cluster, as the group of systems is known, also includes 168 separate graphical processing units and 84 coordinating servers in a parallel array capable of performing 500 trillion floating point operations per second (500 TFLOPS), according to AFRL Director of High Power Computing Mark Barnell."

Americans Less Healthy, But Outlive Brits 521

An anonymous reader writes with this intriguing snippet: "Older Americans are less healthy than their English counterparts, but they live as long or even longer than their English peers, according to a new study by researchers from the RAND Corporation and the Institute for Fiscal Studies in London. Researchers found that while Americans aged 55 to 64 have higher rates of chronic diseases than their peers in England, they died at about the same rate. And Americans age 65 and older — while still sicker than their English peers — had a lower death rate than similar people in England, according to findings published in the journal Demography."

Real Reason Why the White iPhone 4 Is Delayed 182

tekgoblin writes "There have been numerous reasons why the White iPhone 4 may be delayed with one reason being the color mismatch between the home button and the body. Well this time there is another reason. A source has told CultofMac that the reason for the delay is a light leakage issue caused by the case being clear. Light from the case leaks into pictures taken by the back and front camera on the white iPhone 4, causing distorted pictures. This problem is non-existent on the black iPhone 4, because of its already black case, so Apple has been looking for a solution to this problem, thus the delay of the White iPhone 4 till spring of next year."

UK Man Prevented From Finding Chipped Pet Under Data Protection Act 340

Dave Moorhouse was elated when he was informed that a microchip provider had information on the whereabouts of his stolen dog. This joy soon faded when the company informed him that it could not divulge the Jack Russell terrier's location because it would breach the Data Protection Act. Last week a court agreed with the chip company and refused Mr Moorhouse's request for a court order compelling them to reveal the name and address of the new owners. Steven Wildridge, managing director of the chip company said: “This is not a choice, it’s an obligation under the Data Protection Act. If the individuals involved do not want us to pass on their details to the original owner then we cannot do so unless compelled to following a criminal or civil proceeding."

How a Key Enzyme Repairs Sun-Damaged DNA 97

BraveHeart writes "Researchers have long known that mammals, including humans, lack a key enzyme — one possessed by most of the animal kingdom and even plants — that reverses severe sun damage. For the first time, researchers have witnessed how this enzyme works at the atomic level to repair sun-damaged DNA. 'Normal sunscreen lotions convert UV light to heat, or reflect it away from our skin. A sunscreen containing photolyase could potentially heal some of the damage from UV rays that get through.'"
