sandbagger writes: Printer ink is expensive, so it's important that when a printer tells you a cartridge is running dry, the cartridge is actually running dry. Unfortunately, that's not always the case. The folks over at Bellevue Fine Art in Seattle recently decided to find out exactly how much ink their high-end Epson 9900 printer wastes. A professional grade 700ml cartridge will have 120-150ml remaining when "empty," and a 350ml cartidge will have 60-80ml remaining when "empty." For this studio, the difference amounts to hundreds of dollars worth of ink every month.

biobricks writes: The NY Times covers cryonics and destructive mind uploading, with some news on progress in brain preservation research. Quoting: "Dr. Fahy, a cryobiologist whose research focuses on organ banking, had provided the most encouraging signs that cryonics did preserve brain structure. In a 2009 experiment, his team showed that neurons in slices of rabbit brains immersed in the solution, chilled to cryogenic temperatures and then rewarmed, had responded to electrical stimulation. His method, he contended, preserved the connectome in those slices. But a complication prevented him from entering the prize competition: Brain tissue perfused with the cryoprotectant invariably becomes dehydrated, making it nearly impossible to see the details of the shrunken neurons and their connections under an electron microscope. ... He could fix the brain’s structure in place with chemicals first, just as Dr. Mikula was doing, buying time to perfuse the cryoprotectant more slowly to avoid dehydration. But he lacked the funds, he said, for a project that would have no practical business application for organ banking."

MojoKid writes: Researchers from Purdue University have developed a software tool for Android smartphones that purportedly slows down battery drain when handsets enter a sleep state. With the software tool installed, the researchers claim that smartphone battery life can be extended by nearly 16 percent. Called "HUSH," the software solution was developed in response to what the researchers say is the first large-scale study of smartphone energy drain occurring from everyday use by consumers. According to their research, apps drain 28.9 percent of battery power while the screen is turned off. HUSH dynamically identifies app background activities that it deems aren't useful to the user experience on a per-app basis and suppresses those apps when the screen is turned off.

He said, "As communication forms evolve, it will be important to preserve one of the oldest: the letter, which has been critical in building relationships, conducting business and governmental affairs, and preserving history. Rather than sounding the death knell for meaningful, written correspondence, Internet technology has the power to enhance it." Cerf cites Doris Kearns Goodwin's book Team of Rivals: The Political Genius of Abraham Lincoln as a perfect example of what might not be possible for historians of the next generation. Goodwin pieced together letters written by President Lincoln and his cabinet to write a book about how they interacted. "In the case of Doris Kearns Goodwin, the letters were 140 years old, and I would guess that digital content that was created 10 years ago won't be accessible 10 years from now," said Cerf. "We have the media around, but you may not be able to read it."

theodp writes: The Washington Technology Industry Association (WTIA) says a $3.5 million U.S. Dept. of Labor grant will help it create a registered apprenticeship program that aims to train 600 people over the next five years. Participants would pay tuition for 3-4 months of pre-apprenticeship training and then be placed with an employer such as Microsoft, Accenture, F5 Networks, or Impinj for a paid apprenticeship lasting 12-18 month, which organizers hope will lead to a permanent position. Candidates will begin with a series of assessments to gauge their potential to learn computer science fundamentals. For those who pass the WTIA's tech skills assessment, next is a pre-apprenticeship training, which is estimated to cost between $5,000 and $10,000 per person. The training will follow existing certificate programs, such as those developed by Microsoft for military veterans transitioning to new careers in tech. The Get in I.T. Apprenticeship program, the White House explains, "will target recruiting women, people of color, and transitioning military members."

Joe_Dragon writes with news that the European Court of Justice has issued a ruling (PDF) saying that workers who have to commute to see customers, but don't have a "fixed or habitual place of work," must have their transit time at the beginning and end of the day count as working time. In other words, driving to your normal office every day doesn't count toward your paycheck, but leaving home in the morning to go visit a client or customer at your employer's request does. This added commute time also counts toward weekly labor limits — EU regulations for working conditions prohibit employers from making their employees work more than 48 hours a week on average. The court said, Given that traveling is an integral part of being such a worker, the place of work of that worker cannot be reduced to the physical areas of his work on the premises of the employer’s customers. The fact that the workers begin and finish the journeys at their homes stems directly from the decision of their employer to abolish the regional offices and not from the desire of the workers themselves.

This adds support for the amdgpu driver, fixes for non-Windows platforms, new OpenGL ES extensions supported, and more. Most notable is the support for all extensions in OpenGL 4.1 by the radeonsi and nvc0 drivers, and support for extensions added in OpenGL 4.2 by the i965 driver. This brings the OpenGL version supported by core Mesa from 3.3 to 4.2, five and a half years after OpenGL 4 was released. Mesamatrix gives the status of which OpenGL extensions are supported by which open source driver. Vulkan, on the otherhand, will have an open source driver once the spec is released.

An anonymous reader writes: Earlier this year, Carnegie Mellon had one of the most capable robotics research centers in the world. Then, Uber hired away dozens of workers in a frantic push to jump start development of autonomous driving technology, which left CMU reeling. Now the NY Times asks whether such high-tech labs can continue to exist; Silicon Valley seems ready to flood such organizations with money whenever a vital new technology is almost ripe. "Carnegie Mellon's experience is a familiar one in the world of high-tech research. As a field matures, universities can wake up one day to find money flooding the premises; suddenly they're in a talent war with deep-pocketed firms from Silicon Valley. The impacts are also intellectual. When researchers leave for industry, their expertise winks off the map; they usually can't publish what they discover — or even talk about it over drinks with former colleagues. ... [Also], the intellectual register of their work changes. No more exploring hard, ''basic'' problems out of deep curiosity; they need to solve problems that will make their employers money."

An anonymous reader writes: USA TODAY obtained records through a Freedom of Information Act request indicating that the U.S. Department of Energy was targeted by over a thousand cyberattacks between October 2010 and October 2014. 159 of the attacks were successful in compromising some level of security. "Energy Department officials would not say whether any sensitive data related to the operation and security of the nation's power grid or nuclear weapons stockpile was accessed or stolen in any of the attacks, or whether foreign governments are believed to have been involved. ... The National Nuclear Security Administration, a semi-autonomous agency within the Energy Department responsible for managing and securing the nation's nuclear weapons stockpile, experienced 19 successful attacks during the four-year period, records show. ... Records show 53 of the 159 successful intrusions from October 2010 to October 2014 were 'root compromises,' meaning perpetrators gained administrative privileges to Energy Department computer systems."

An anonymous reader writes: Security reporter Brian Krebs, who has been instrumental in breaking news about the Ashley Madison hack, is now being threatened by the website's former CTO with a libel suit. Contained in the leaked data was a series of emails from the ex-CTO, Raja Bhatia, to the CEO of Ashley Madison's parent company. In the emails, Bhatia noted a security hole in a competing website, saying that he downloaded their user database and was capable of modifying and exposing it. After reporting on these emails, Krebs received a letter from Bhatia's lawyer (PDF) saying the post was libelous and defamatory. They demanded a retraction, which Krebs is thus far unwilling to do.

An anonymous reader writes: Tim Wu at the New Yorker wonders about the present and future of Google Books. He calls it the most ambitious library project of our time — it seemed so promising when it started. Google developed the requisite technology, made the necessary partnerships to get it done, and put ridiculous amounts of effort into it. Despite their accomplishment, Google Books is merely a shadow of what it could have been. They just couldn't fight through the intellectual property issues that arose. "If Google was, in truth, motivated by the highest ideals of service to the public, then it should have declared the project a non-profit from the beginning, thereby extinguishing any fears that the company wanted to somehow make a profit from other people's work.

Unfortunately, Google made the mistake it often makes, which is to assume that people will trust it just because it's Google. For their part, authors and publishers, even if they did eventually settle, were difficult and conspiracy-minded, particularly when it came to weighing abstract and mainly worthless rights against the public's interest in gaining access to obscure works. Finally, the outside critics and the courts were entirely too sanguine about killing, as opposed to improving, a settlement that took so many years to put together, effectively setting the project back a decade if not longer."

Required Snark writes: The FBI and Department of Justice have withdrawn their prosecution (or more accurately persecution) Dr. Xi Xiaoxing, former head of the Physics Department at Temple University, according to the New York Times. He was accused of attempting to transfer technology about a "pocket heater" to China. It is used in superconducting research.

The case fell apart because the evidence that the FBI had was not about a pocket heater. "In a sworn affidavit, one engineer, Ward S. Ruby, said he was uniquely qualified to identify a pocket heater. 'I am very familiar with this device, as I was one of the co-inventors,' he said." Apparently nobody in the FBI or DOJ bothered to verify that the information referred to the device in question: "Dr. Xi's lawyer, Peter Zeidenberg, said that despite the complexity, it appeared that the government never consulted with experts before taking the case to a grand jury. As a result, prosecutors misconstrued the evidence, he said."

Dr Xi was forced to step down from his position as the head of the department during the investigation. He was unable to work on his ongoing experiments and was branded a spy. What are the odds that anyone at the FBI or DOJ will face any personal or professional repercussions? If recent history is any guide they will not even issue a statement. When the case was withdrawn the option to refile was retained, a blatant attempt to save face and deny responsibility.

An anonymous reader writes: The stereotype of the scientist or engineer is that he prefers facts, reason, and objectivity over more artistic pursuits. But the Priceonomics blog points out an interesting correlation: "the more accomplished a scientist is, the more likely they are to have an artistic hobby." It continues, "The average scientist is not statistically more likely than a member of the general public to have an artistic or crafty hobby. But members of the National Academy of Sciences and the Royal Society — elite societies of scientists, membership in which is based on professional accomplishments and discoveries — are 1.7 and 1.9 times more likely to have an artistic or crafty hobby than the average scientist is. And Nobel prize winning scientists are 2.85 times more likely than the average scientist to have an artistic or crafty hobby." Is this more evidence that we in the science and tech fields undervalue art and pure creativity?

A similar unofficial agreement between copyright holders and payment processors is actively being enforced in countries like the U.S. and the U.K.

jmcbain writes: I am an software engineer for a client-server user account system handling both Web and smartphone clients. I have been searching for definitive and crystal-clear best practices for managing user account and password data using open-source software, but I have only cobbled together a complete picture from dozens of websites. I currently have a system that sends passwords over SSL and performs bcrypt hashing for storage and authentication checking at the server side. Is that good enough? The recent Ashley Madison breach and the exposure of MD5-hashed passwords (as opposed to bcrypt) has me worried again. Can someone please suggest a definitive, cookbook-style Web resource or book on how to use open-source software to handle user passwords for multiple client-server scenarios? I would like answers to questions such as: Where do I perform hashing (smartphone/web client or server)? What hash algorithm should I use? How do I store the hashes? How can clients recover forgotten passwords? etc.

alphadogg writes: It was retail remodeling that spurred NCR, a venerable cash-register company, to find out how it could use newly opened frequencies to link registers and mainframes without wires. Its customers wanted to stop drilling new holes in their marble floors for cabling every time they changed a store layout. In 1985, the U.S. Federal Communications Commission voted to leave large blocks of spectrum unlicensed and let vendors build any kind of network they wanted as long as they didn't keep anyone else from using the frequencies. NCR jumped at the chance to develop a wireless LAN, something that didn't exist at the time, according to Vic Hayes, a former engineer at the company who's been called the Father of Wi-Fi.
