States Are Moving To Cut College Costs By Introducing Open-Source Textbooks
In an effort to curb the rising cost of textbooks, which went up by 88% between 2006 and 2016, according to the U.S. Bureau of Labor Statistics, Maryland and New York have
announced initiatives that adopt open-source, copyright-free textbooks. The initiatives will reward colleges who adapt or scale the use of OER (open educational resources) -- "materials like electronic textbooks that typically use licenses that are far less restrictive than traditional, copyrighted textbooks," reports Quartz. From the report:
The University System of Maryland recently announced that it would be giving out 21 "mini-grants" to seven community colleges and five public four-year schools. The grants will go to "faculty who are adopting, adapting or scaling the use of OER [open educational resources] in Fall 2017 through high-enrollment courses where quality OER exists," according to the announcement. Although the mini-grants are only $500 to $2,500 each, the effort in Maryland is expected to save 8,000 students up to $1.3 million in the Fall 2017 semester alone. That's a significant amount, but just a drop in the bucket of what students in the state spend on textbooks each year. Another big investment in open educational resources came in the budget passed in New York state last week. The news was somewhat buried by the fact that the budget includes free tuition for New York students whose families make up to $125,000 a year, but the state will also be putting $8 million into open source materials over the next fiscal year.
First Evidence For Higher State of Consciousness Found
baalcat quotes a report from Neuroscience News:
Neuroscientists observed a sustained increase in neural signal diversity -- a measure of the complexity of brain activity -- of people under the influence of psychedelic drugs, compared with when they were in a normal waking state. The diversity of brain signals provides a mathematical index of the level of consciousness. For example, people who are awake have been shown to have more diverse neural activity using this scale than those who are asleep. This, however, is the first study to show brain-signal diversity that is higher than baseline, that is higher than in someone who is simply "awake and aware." Previous studies have tended to focus on lowered states of consciousness, such as sleep, anesthesia, or the so-called "vegetative" state. For the study, Michael Schartner, Dr Adam Barrett and Professor Seth of the Sackler Center reanalyzed data that had previously been collected by Imperial College London and the University of Cardiff in which healthy volunteers were given one of three drugs known to induce a psychedelic state: psilocybin, ketamine and LSD. Using brain imaging technology, they measured the tiny magnetic fields produced in the brain and found that, across all three drugs, this measure of conscious level -- the neural signal diversity -- was reliably higher. The findings have been
published in Scientific Reports.
Navy, Marines Prohibit Sharing Nude Photos In Wake of a Facebook Scandal
An anonymous reader quotes a report from Fortune:
The Navy and Marine Corps issued new regulations that ban members from sharing nude photographs following a scandal involving military personnel sharing intimate pictures of their female colleagues -- some of which were taken without their knowledge -- in a secret Facebook group. The new statute, which was signed Tuesday by Acting Navy Secretary Sean Stackley, went into effect immediately and will be made permanent when the next edition of the Navy's regulations is printed, according to Navy Times. Military courts will handle violations of the new rule. The crackdown comes after a Facebook group was uncovered featuring naked photos of female service members. The group was eventually shut down by Facebook after a request from the Marine Corps. The Center for Investigative Reporting found that some of the photographs posted on the Facebook group may have been taken consensually, but others may not have been.
Ask Slashdot: What Are Good Books On Inventing, Innovating and Doing R&D?
I've signed up to a project that involves inventing new ways to do things and also performing the technology R&D required to make these new ways a reality. So, dear Slashdotters, are there any good books on inventing, innovating or doing R&D? Books that describe different ways to approach inventing/R&D? Books on managing a team effort to invent, innovate and research? Or even good books about the history of past inventions -- how they were created, why they were created, how and why they succeeded or failed in the real world? Thanks!
Toyota Unveils Plan For Hydrogen Powered Semi Truck
omaha393 quotes a report from R&D Magazine:
Toyota announced a new initiative on Wednesday aimed at advancing its work in vehicles powered by alternative energy sources. The automaker unveiled Project Portal, which is a novel hydrogen fuel cell system designed for heavy duty truck use at the Port of Los Angeles. A proof-of-concept truck powered by this fuel cell will be part of a feasibility study held at the Port this summer, with the goal of examining the potential of this technology in heavy-duty applications. The test vehicle will produce more than 670 horsepower and 1,325 pound feet of torque from two of these novel fuel cell stacks along with a 12kWh battery. Overall, the combined weight capacity is 80,000 pounds that will be carried over 200 miles.
omaha393 adds: "While hydrogen fuel has been criticized due to high cost of production and safety concerns, recent advances in catalysis and solid storage systems have made the prospect of hydrogen fuel an attractive commercial prospect for the future."
Tesla Settles Lawsuit Against Former Autopilot Program Director Accused of Stealing Info, Engineers
Earlier this year, Tesla
filed a lawsuit against its former director of Autopilot Programs, Sterling Anderson, for stealing proprietary information about the Autopilot program and recruiting fellow Tesla engineers to work with him at Aurora Innovation, another autonomous driving company. According to Electrek, "the lawsuit was
settled today with Tesla withdrawing their allegations without damages and Aurora agreeing to make itself available for an audit by a third-party to make sure they don't have proprietary information from Tesla's Autopilot program." From the report:
Aurora also agreed to cover the cost of the audit for up to $100,000. The startup claims that it had already ordered its own audit, which found âoeno material Tesla confidential information." As for the allegations of poaching employees, Aurora has agreed not to reach out to Tesla employees for a year and to release the names of former Tesla employees who have joined the startup already. You can read Auroraâ(TM)s statement about the settlement in full here and Teslaâ(TM)s further down below: âoeSelf-driving vehicles will save lives, preserve resources, and make transportation more accessible and enjoyable for everyone. Aurora was founded on the premise that experience, innovative thinking, hard work, and a commitment to doing the right thing can accelerate this future..."
Microsoft's Skype Is Most Used Messaging Service For Cyber Criminals, Study Finds
chicksdaddy quotes a report from The Security Ledger:
Cyber criminals lurk in the dark recesses of the internet, striking at random and then disappearing into the virtual ether. But when they want to talk shop with their colleagues, they turn to Redmond, Washington-based Microsoft and its Skype communications tools, according to an analysis by the firm Flashpoint. Mentions of different platforms were used as a proxy for gauging interest in and use of these messaging services. Flashpoint analysts looked, especially, for invitations to continue conversation outside of cyber criminal marketplaces, like references to ICQ accounts or other platforms. The survey results show that, out of a population of around 80 instant messenger platforms and protocols, a short list of just five platforms accounts for between 80% and 90% of all mentions within the cyber underground. Of those, Microsoft's Skype was the chat king. It ranked among the top five platforms across all language groups. That, despite the platform's lack of end-to-end encryption or forward secrecy features and evidence, courtesy of NSA hacker Edward Snowden, that U.S. spies may have snooped on Skype video calls in recent years, The Security Ledger reports. The conclusion: while security is a priority amongst thieves, it isn't the sole concern that cyber criminals and their associates have. In fact, sophisticated hacking communities like those in Russia to continue to rely on legacy platforms like ICQ when provably more secure alternatives exist. The reason? Business. "These cyber criminals have a lot of different options that they're juggling and a lot of factors that weigh on their options," said Leroy Terrelonge III, the Director of Middle East and Africa Research at Flashpoint. "We might suspect that cyber criminals use the most secure means of communication all the time, that's not what our research showed."
Pirate Bay Founder Launches Anonymous Domain Registration Service
An anonymous reader quotes a report from TorrentFreak:
Former Pirate Bay spokesperson and co-founder Peter Sunde has just announced his latest venture. Keeping up his fight for privacy on the Internet, he's launching a new company called Njalla, that helps site operators to shield their identities from prying eyes. The name Njalla refers to the traditional hut that Sami people use to keep predators at bay. It's built on a tall stump of a tree or pole and is used to store food or other goods. On the Internet, Njalla helps to keep people's domain names private. While anonymizer services aren't anything new, Sunde's company takes a different approach compared to most of the competition. With Njalla, customers don't buy the domain names themselves, they let the company do it for them. This adds an extra layer of protection but also requires some trust. A separate agreement grants the customer full usage rights to the domain. This also means that people are free to transfer it elsewhere if they want to.
Facebook is Working On a Way To Let You Type With Your Brain
From a report:
Facebook today unveiled a project from its secretive Building 8 research group that's working to create a brain-computer interface that lets you type with your thoughts. Regina Dugan, a former director of DARPA and the ex-head of Google's experimental ATAP research group, announced the news today onstage at Facebook's F8 developer conference. Dugan, who now heads up Building 8, says the goal is "something as simple as a yes-no brain click" that could fundamentally change how we interact with and use technology. While it does not exist today outside of very specific medical research trials, Dugan says her team is actively working to make it a reality. Dugan refers to the technology as a "brain mouse for AR," meaning it could be an ideal way to receive direct input from neural activity that would remove the need for augmented reality devices to track hand motions or other body movements. For instance, the Microsoft HoloLens uses hand tracking to let you tap your finger in front of you as if you were clicking a mouse. Facebook's theoretical device could also be used for patients with severe paralysis, acting as a "speech prosthetic" Dugan says.
Newest Firefox Browser Bashes Crashes
Nobody likes it when a web browser bombs instead of opening up a website. Mozilla is addressing that in the newly released v53 of its Firefox browser, which it claims crashes 10 percent fewer times. CNET adds:
The improvement comes through the first big debut of a part of Project Quantum, an effort launched in 2016 to beef up and speed up Firefox. To improve stability, Firefox 53 on Windows machines isolates software called a compositor that's in charge of painting elements of a website onto your screen. That isolation into a separate computing process cuts down on trouble spots that can occur when Firefox employs computers' graphics chips, Mozilla said.
Ubuntu Is Switching to Wayland
An anonymous reader shares a report:
Ubuntu is to ship Wayland in place of X.Org Server by default. Mir, Canonical's home-spun alternative to Wayland, had been billed as the future of Ubuntu's convergence play. But both Unity 8 the convergence dream was recently put out to pasture, meaning this decision was widely expected. It's highly likely that the traditional X.Org Server will, as on Fedora, be included on the disc and accessible from whichever login screen Ubuntu devs opt to use in ubuntu 17.10 onwards. This session will be useful for users whose system experience issues running on Wayland, or who need features and driver support that is only present in the legacy X.Org server session.
TED Wants To Remind Us That Ideas -- Not Politicians -- Shape the Future
An anonymous reader shares a Quartz report:
Amid global political upheavals, TED curator Chris Anderson argues that ideas have never mattered more. "Ideas changes how people act and [shape] their long term perspective," he said in during a April 17 press briefing. "Politicians come and go and ideas are forever." He said TED -- two segments of which will be broadcast live in movie theaters this year -- wants to re-introduce civility into political discourse. "We want to avoid the zero sum game we see on cable television every day," said Anderson, noting that TED is a non-partisan organization and has historically featured controversial and intriguing thinkers from both sides of the political divide. In place of the shrill, headline-bait tenor of political spectacles, TED wants to take viewers to a place of "reasoned discourse" where big ideas can act as a bridge between opposing views. By creating an eclectic program -- including an entire session delivered in Spanish and another on artificial intelligence -- Anderson said he wants to steer the conversation away from government and politics. "With so much focus in politics, the world is in danger of forgetting that so much of what really changes the future happens outside completely of politics. It happens inside the mind of dreamers, designers, inventors, technologists, entrepreneurs," he said.
Nintendo To Launch SNES Mini This Year, Reports Eurogamer
Nintendo plans to release another console this year aimed at nostalgia-seekers. The iconic game company is
working on a Super Nintendo Entertainment System (SNES) classic version that would launch in time for the holidays, according to Eurogamer, which cites sources with knowledge of the plans. The device is already under development and -- like its predecessor the NES Classic Edition -- will give gamers access to some of the console's biggest hits. From the article:
Nintendo's plans for SNES mini are also a major reason why last year's NES mini did not see a reprieve from discontinuation, Eurogamer understands, despite the latter's continued popularity and sell-out status.
Silicon Valley's $400 Juicer May Be Feeling the Squeeze
An anonymous reader shares a Bloomberg report:
One of the most lavishly funded gadget startups in Silicon Valley last year was Juicero Inc. It makes a juice machine. The product was an unlikely pick for top technology investors, but they were drawn to the idea of an internet-connected device that transforms single-serving packets of chopped fruits and vegetables into a refreshing and healthy beverage. Doug Evans, the company's founder, would compare himself with Steve Jobs in his pursuit of juicing perfection. He declared that his juice press wields four tons of force -- "enough to lift two Teslas," he said. Google's venture capital arm and other backers poured about $120 million into the startup. Juicero sells the machine for $400, plus the cost of individual juice packs delivered weekly. But after the product hit the market, some investors were surprised to discover a much cheaper alternative: You can squeeze the Juicero bags with your bare hands. Two backers said the final device was bulkier than what was originally pitched and that they were puzzled to find that customers could achieve similar results without it.

Bose Headphones Secretly Collected User Data, Lawsuit Reveals
The audio maker Bose, whose wireless headphones sell for up to $350,
uses an app to collect the listening habits of its customers and provide that information to third parties -- all without the knowledge and permission of the users, according to a lawsuit filed in Chicago. From a report:
The complaint accuses Boston-based Bose of violating the WireTap Act and a variety of state privacy laws, adding that a person's audio history can include a window into a person's life and views. "Indeed, one's personal audio selections -- including music, radio broadcast, Podcast, and lecture choices -- provide an incredible amount of insight into his or her personality, behavior, political views, and personal identity," says the complaint, noting a person's audio history may contain files like LGBT podcasts or Muslim call-to-prayer recordings.
Facebook Owns Four Out of the Five Most Downloaded Apps Worldwide
An anonymous reader shares a report:
Facebook continues to storm the numbers as the company has claimed four out of the five spots for the most downloaded apps across the globe during the last quarter. Interestingly, Netflix still lords over everyone as far as revenue goes. New research by app analytics firm Sensor Tower reveals that WhatsApp, Facebook, Messenger, Instagram and Snapchat were the most downloaded apps for the first three months of this year. While the numbers differed across the App Store and Google Play, one thing both platforms shared is that Facebook owned four out of the top five spots for the most downloaded apps worldwide. While Messenger topped the App Store download charts, Facebook headed the race on Google Play.
Baidu Announces New Open Platform To Help Speed Up Development of Self-Driving Cars
Chinese tech giant Baidu has
announced a new autonomous vehicle platform called Project Apollo, which
aims to help speed up the development of self-driving cars. "Baidu says the platform encompasses both hardware and software, providing partners with the tech and open-source code needed to help their own vehicles perceive obstacles, plan their routes, and otherwise move around our world," reports The Verge. From the report:
Baidu says it will first open up Project Apollo for cars operating in restricted environments in July, before offering it to vehicles driving in simple urban road conditions later this year. That's ahead of a gradual rollout of self-driving features that should see cars operating fully autonomously on highways and regular roads by 2020. The release comes as Baidu moves to position itself at the forefront of the autonomous vehicle industry. The Chinese company has aimed for the ambitious goal of getting a self-driving car to market by 2018, and is challenging rivals such as Google on its home turf, building a team of engineers based in Silicon Valley and scoring relevant permits so it can test vehicles in California.
Scientists Invent Ultrasonic Dryer That Uses Sound To Dry Your Clothes
An anonymous reader quotes a report from Yahoo:
Scientists at Oak Ridge National Laboratory in Tennessee have developed a dryer that could make doing laundry much quicker. Called the ultrasonic dryer, it's expected to be up to five times more energy efficient than most conventional dryers and able dry a large load of clothes in about half the time. Instead of using heat the way most dryers do, the ultrasonic dryer relies on high-frequency vibrations. Devices called green transducers convert electricity into vibrations, shaking the water from clothes. The scientists say that this method will allow a medium load of laundry to dry in 20 minutes, which is significantly less time than the average 50 minutes it takes in many heat-based machines. The drying technology also leaves less lint behind than normal dryers do, since the majority of lint is created when the hot air stream blows tiny fibers off of clothing. Drying clothes without heat also reduces the chance that their colors will fade. While the ultrasonic dryer has been in development for the past couple of years, the U.S. Department of Energy explains in
a published video that it has recently been "developed into a full-scale press dryer and clothes dryer drum -- setting the stage for it to one day go to market through partners like General Electric Appliances."
Broadband Expansion Could Trigger Dangerous Surge In Space Junk
A new study from the University of Southampton warns that expanding broadband networks via launching "mega constellations" of thousands of communications satellites
could increase catastrophic crashes of dangerous space junk in Earth's orbit. "Dr Hugh Lewis, a senior lecturer in aerospace engineering at the University of Southampton, ran a 200-year simulation to assess the possible consequences of such a rise in orbital traffic," reports The Guardian. "He found it could create a 50% increase in the number of catastrophic collisions between satellites." From the report:
Such crashes would probably lead to a further increase in the amount of space junk in orbit, he said, leading to the possibility of further collisions and potential damage to the services the satellites were intended to provide. The European Space Agency, which funded Lewis's research, is calling for the satellites planned for orbital mega-constellations to be able to move to low altitudes once their missions are over so they burn up in Earth's atmosphere. They must also be able discharge all batteries, fuel tanks and pressure tanks to prevent explosions that would scatter debris. Lewis is presenting his research this week at the European conference on space debris at the ESA's center in Darmsadt, Germany. Krag said he expected some of the companies planning launches to attend.
