A Tower of Molten Salt Will Deliver Solar Power After Sunset (ieee.org)
schwit1 sends this report from IEEE Spectrum: Solar power projects intended to turn solar heat into steam to generate electricity have struggled to compete amid tumbling prices for solar energy from solid-state photovoltaic (PV) panels. But the first commercial-scale implementation of an innovative solar thermal design could turn the tide. Engineered from the ground up to store some of its solar energy, the 110-megawatt plant is nearing completion in the Crescent Dunes near Tonopah, Nev. It aims to simultaneously produce the cheapest solar thermal power and to dispatch that power for up to 10 hours after the setting sun has idled photovoltaics. ... [The system] heats a molten mixture of nitrate salts that can be stored in insulated tanks and withdrawn on demand to run the plant’s steam generators and turbine when electricity is most valuable. ... Eliminating the heat exchange between oil and salts trims energy storage losses from about 7 percent to just 2 percent. The tower also heats its molten salt to 566 degrees C, whereas oil-based plants top out at 400 degrees C.

Google, Facebook, Microsoft Deliver K-12 CS Demands To Congress (politico.com)
theodp writes: Politico reports that just one day after Facebook launched TechPrep, a highly-publicized initiative to attract more minorities and women to coding, Google, Facebook, Microsoft, and Code.org quietly sent a letter to top education lawmakers in the House and Senate insisting that computer science "must" be added to the list of "core academic subjects" and states be given resources to improve STEM education programs. "Computer science is marginalized throughout K-12 education," reads the letter. "We need to improve access for all students, particularly groups who have traditionally been underrepresented." Echoing the last point at this month's Grace Hopper Women in Computer Celebration, YouTube CEO Susan Wojcicki called for mandatory computer science in schools, suggesting that boys — like her own son — are monopolizing the family computer across America, leaving girls — like her own daughter — out of the conversation when it comes to technology (video @38:33). The new round of hand-wringing comes as tech companies face the deadline for filing their 2015 EEO-1 surveys and seek more tech-friendly U.S. visa and OPT STEM policies, so it's probably worth remembering that Microsoft proposed tech could turn workforce diversity lemons into H-1B visa lemonade by connecting tech immigration to K-12 CS education.

Europe's 'Net Neutrality' Could Allow Throttling of Torrents and VPNs (torrentfreak.com)
An anonymous reader writes: TorrentFreak reports that the European Parliament is approaching a vote on new telecom regulations that aim to implement net neutrality throughout EU member states. Unfortunately, the legislation hinges on a few key amendments, and experts are warning about the consequences should those amendments fail to pass. "These amendments will ensure that specific types of traffic aren't throttled around the clock, for example. The current language would allow ISPs to throttle BitTorrent traffic permanently if that would optimize overall 'transmission quality.' This is not a far-fetched argument, since torrent traffic can be quite demanding on a network." That's not the only concern: "Besides file-sharing traffic the proposed legislation also allows Internet providers to interfere with encrypted traffic, including VPN connections. Since encrypted traffic can't be classified though deep packet inspection, ISPs may choose to de-prioritize it altogether."

DHS To Extend OPT To 60 Months, Says Employers, Universities, Students Demand It (natlawreview.com)
theodp writes: In August, Federal Judge Ellen Huvelle called BS on 'emergency' changes made by the U.S. Dept. of Homeland Security in 2008 to Optional Practical Training (OPT) that extended the amount of time foreign STEM graduates of U.S. colleges could stay in the country and work ("to alleviate the crisis employers are facing due to the current H-1B visa shortage," as Bill Gates explained it in 2007). "The 17-month duration of the STEM extension appears to have been adopted directly from the unanimous suggestions by Microsoft and similar industry groups," said the Judge in her ruling, which threatened to invalidate STEM OPT extensions in February. But the DHS fired back Monday with a new proposed rule — Improving and Expanding Training Opportunities for F-1 Nonimmigrant Students With STEM Degrees and Cap-Gap Relief for All Eligible F-1 Students — that will extend STEM OPT to as much as 60 months (a standard 12-month OPT period, plus two 24-month extensions). Foreign students demand it, explained the DHS, as do public colleges and universities, who "particularly benefit from the payment of tuition by foreign students, especially in comparison to the tuition paid by in-state students." DHS estimates that the proposed rule will affect 634,464 foreign STEM students over the next 10 years.

How Is the NSA Breaking So Much Crypto? (freedom-to-tinker.com)
schwit1 writes: There have been rumors for years that the NSA can decrypt a significant fraction of encrypted Internet traffic. In 2012, James Bamford published an article quoting anonymous former NSA officials stating that the agency had achieved a "computing breakthrough" that gave them "the ability to crack current public encryption." The Snowden documents also hint at some extraordinary capabilities: they show that NSA has built extensive infrastructure to intercept and decrypt VPN traffic and suggest that the agency can decrypt at least some HTTPS and SSH connections on demand.
However, the documents do not explain how these breakthroughs work, and speculation about possible backdoors or broken algorithms has been rampant in the technical community. Yesterday at ACM CCS, one of the leading security research venues, we and twelve coauthors presented a paper that we think solves this technical mystery.
If a client and server are speaking Diffie-Hellman, they first need to agree on a large prime number with a particular form. There seemed to be no reason why everyone couldn't just use the same prime, and, in fact, many applications tend to use standardized or hard-coded primes. But there was a very important detail that got lost in translation between the mathematicians and the practitioners: an adversary can perform a single enormous computation to "crack" a particular prime, then easily break any individual connection that uses that prime. -
Ask Slashdot: Is There Space For Open Hardware In Networking?
New submitter beda writes: Open hardware has got much attention with the advent of Raspberry Pi, Arduino and their respective clones. But most of the devices are focused either on tinkerers (Arduino) or most notably multimedia (Raspberry Pi). However, there is not much happening in other areas such as home routers where openness might help improve security and drive progress. Our company (non-profit) is trying to change this with Turris Omnia but we still wander if there is in fact demand for such devices. Is the market large enough and the area cool enough? Are there enough people who would value open hardware running open software even with a higher price tag? Any feedback would be most valued.

Playboy Drops Nudity As Internet Fills Demand
HughPickens.com writes: Ravi Somaiya reports in the NY Times that as part of a redesign that will be unveiled next March, the print edition of Playboy Magazine will still feature women in provocative poses but they will no longer be fully nude. "That battle has been fought and won," says CEO Scott Flanders. "You're now one click away from every sex act imaginable for free. And so it's just passé at this juncture." According to Somaiya, for a generation of American men, reading Playboy was a cultural rite, an illicit thrill consumed by flashlight. Now every teenage boy has an Internet-connected phone instead. Pornographic magazines, even those as storied as Playboy, have lost their shock value, their commercial value and their cultural relevance. The magazine will adopt a cleaner, more modern style. There will still be a Playmate of the Month, but the pictures will be "PG-13" and less produced — more like the racier sections of Instagram. "A little more accessible, a little more intimate," says Flancers. It is not yet decided whether there will still be a centerfold.

Can a New Type of School Churn Out Developers Faster? (dice.com)
Nerval's Lobster writes: Demand for software engineering talent has become so acute, some denizens of Silicon Valley have contributed to a venture fund that promises to turn out qualified software engineers in two years rather than the typical four-year university program. Based in San Francisco, Holberton School was founded by tech-industry veterans from Apple, Docker and LinkedIn, making use of $2 million in seed funding provided by Trinity Ventures to create a hands-on alternative to training software engineers that relies on a project-oriented and peer-learning model originally developed in Europe. But for every person who argues that developers don't need a formal degree from an established institution in order to embark on a successful career, just as many people seem to insist that a lack of a degree is an impediment not only to learning the fundamentals, but locking down enough decent jobs over time to form a career. (People in the latter category like to point out that many companies insist on a four-year degree.) Still others argue that lack of a degree is less of an issue when the economy is good, but that those without one find themselves at a disadvantage when the aforementioned economy is in a downturn. Is any one group right, or, like so many things in life, is the answer somewhere in-between?

Charge Rage: Electric Cars Are Making People Meaner In California
HughPickens.com writes: Matt Richtel reports that the push to make the state greener with electric cars is having an unintended side effect: It is making some people meaner. The bad moods stem from the challenges drivers face finding recharging spots for their battery-powered cars. Unlike gas stations, charging stations are not yet in great supply, and that has led to sharp-elbowed competition. According to Richtel, electric-vehicle owners are unplugging one another's cars, trading insults, and creating black markets and side deals to trade spots in corporate parking lots. The too-few-outlets problem is a familiar one in crowded cafes and airports, where people want to charge their phones or laptops. But the need can be more acute with cars — will their owners have enough juice to make it home? — and manners often go out the window. "Cars are getting unplugged while they are actively charging, and that's a problem," says Peter Graf. "Employees are calling and messaging each other, saying, 'I see you're fully charged, can you please move your car?'"
The problem is that installation of electric vehicle charging ports at some companies has not kept pace with soaring demand, creating thorny etiquette issues in the workplace. German software company SAP installed 16 electric vehicle charging ports in 2010 at its Palo Alto campus for the handful of employees who owned electric vehicles. Now there are far more electric cars than chargers. Sixty-one of the roughly 1,800 employees on the campus now drive a plug-in vehicle, overwhelming the 16 available chargers. And as demand for chargers exceeds supply, there have been notorious incidents of "charge rage." Companies are finding that they need one charging port for every two of their employees' electric vehicles. "If you don't maintain a 2-to-1 ratio, you are dead," said ChargePoint CEO Pat Romano. "Having two chargers and 20 electric cars is worse than having no chargers and 20 electric cars. If you are going to do this, you have to be willing to continue to scale it." -
In Midst of a Tech Boom, Seattle Tries To Keep Its Soul
HughPickens.com writes: Nick Wingfield has an interesting article in the NYT about how Seattle, Austin, Boulder, Portland, and other tech hubs around the country are seeking not to emulate San Francisco where wealth has created a widely envied economy, but housing costs have skyrocketed, and the region's economic divisions have deepened with rent for a one-bedroom apartment in San Francisco at more than $3,500 a month, the highest in the country. "Seattle has wanted to be San Francisco for so long," says Knute Berger. "Now it's figuring out maybe that it isn't what we want to be." The core of the debate is over affordable housing and the worry that San Francisco is losing artists, teachers and its once-vibrant counterculture. "It's not that we don't want to be a thriving tech center — we do," says Alan Durning. "It's that the San Francisco and Silicon Valley communities have gotten themselves into a trap where preservationists and local politics have basically guaranteed buying a house will cost at least $1 million. Already in Seattle, it costs half-a-million, so we're well on our way."
Seattle mayor Ed Murray says he wants to keep the working-class roots of Seattle, a city with a major port, fishing fleet and even a steel mill. After taking office last year, Murray made the minimum-wage increase a priority, reassured representatives of the city's manufacturing and maritime industries that Seattle needed them., and has set a goal of creating 50,000 homes — 40 percent of them affordable for low-income residents — over the next decade. "We can hopefully create enough affordable housing so we don't find ourselves as skewed by who lives in the city as San Francisco is," says Murray. "We're at a crossroads," says Roger Valdez. "One path leads to San Francisco, where you have an incredibly regulated and stagnant housing economy that can't keep up with demand. The other path is something different, the Seattle way." -
Why Is RAM Suddenly So Cheap? It Might Be Windows
jfruh writes: The average price of a 4GB DDR3 memory DIMM at the moment $18.50 — a price that's far lower than at this time last year. Why is it so cheap? The memory business tends to go in boom and bust cycles, but the free availability of Windows 10 means that fewer people are upgrading their PCs, reducing RAM demand. Analyst Avril Wu said, "Notebook shipments in the third quarter fall short of what is expected for a traditional peak season mainly because Windows 10 with its free upgrade plan negatively impacted replaced sales of notebooks to some extent rather than driving the demand for these products." And prices might stay low for another two years.

Worries Mount Over Upcoming LTE-U Deployments Hurting Wi-Fi
alphadogg writes: LTE-U is a technology developed by Qualcomm that lets a service provider broadcast and receive signals over unlicensed spectrum, which is usable by anybody – specifically, in this case, the spectrum used by Wi-Fi networks in both businesses and homes. By opening up this new spectrum, major U.S. wireless carriers hope to ease the load on the licensed frequencies they control and help their services keep up with demand. Unsurprisingly, several outside experiments that pitted standard LTE technology or 'simulated LTE-U' technology, in the case of one in-depth Google study, against Wi-Fi transmitters on the same frequencies found that LTE drastically reduced the throughput on the Wi-Fi connection.

EFF Joins Nameless Coalition and Demands Facebook Kills Its Real Names Policy
Mark Wilson writes: Facebook has seen heavy criticism for its real names (or 'authentic identities' as they are known to the social network) policy. Over the last year, all manner of rights groups and advocates have tried to convince Facebook to allow users to drop their real name in favor of a pseudonym if they want. Now the Electronic Frontier Foundation is part of the 74-member strong Nameless Coalition and has written to Facebook demanding a rethink on the ground of safety, privacy, and equality. This is far from being the first time Facebook has been called on to allow the use of 'fake names', and the latest letter is signed by LGBT groups, freedom advocates, privacy supporters, and feminist organizations.

What Non-Geeks Hate About the Big Bang Theory
v3rgEz writes: It has been said that there is a lot to dislike about the Big Bang Theory, from the typical geek's point of view: It plays in stereotypes of geekdom for cheap laughs, makes non-sensical gags, and has a laugh track in 2015. But what does the rest of America (well, the part of America not making it the number one show on television) think? FCC complaints recently released accuse the show of everything from animal cruelty to subliminal messaging, demanding that the sitcom be ripped from the airwaves lest it ruin America. The full complaints for your reading pleasure.

Phone Passwords Protected By 5th Amendment, Says Federal Court
Ars Technica reports that a Federal court in Pennsylvania ruled Wednesday that the Fifth Amendment protects from compelled disclosure the passwords that two insider-trading suspects used on their mobile phones. In this case, the SEC is investigating two former Capital One data analysts who allegedly used insider information associated with their jobs to trade stocks—in this case, a $150,000 investment allegedly turned into $2.8 million. Regulators suspect the mobile devices are holding evidence of insider trading and demanded that the two turn over their passcodes. However, the court ruled, "Since the passcodes to Defendants' work-issued smartphones are not corporate records, the act of producing their personal passcodes is testimonial in nature and Defendants properly invoke their fifth Amendment privilege."

Google Launches Brotli, a New Open Source Compression Algorithm For the Web
Mark Wilson writes: As websites and online services become ever more demanding, the need for compression increases exponentially. Fans of Silicon Valley will be aware of the Pied Piper compression algorithm, and now Google has a more efficient one of its own. Brotli is open source and is an entirely new data format that offers 20-26 percent greater compression than Zopfli, another compression algorithm from Google. Just like Zopfli, Brotli has been designed with the internet in mind, with the simple aim of making web pages load faster. It is a "lossless compressed data format that compresses data using a combination of the LZ77 algorithm and Huffman coding, with efficiency comparable to the best currently available general-purpose compression methods". Compression is better than LZMA and bzip2, and Google says that Brotli is "roughly as fast" as zlib's Deflate implementation.

India's Worrying Draft Encryption Policy
knwny writes: The government of India is working on a new National Encryption Policy the contents of which have raised a few alarms.Among other things, the policy states that citizens and businesses must save all encrypted messages (including personal or unofficial ones) and their plaintext copies for 90 days and make them available to law enforcement agencies as and when demanded. The policy also specifies that only the government of India shall define the algorithms and key sizes for encryption in India. The policy is posted on this website.

How Wind and Politics Pushed the Price of Texas Electricity Below Zero
Slate dissects the strange circumstances that led the price of electricity in Texas to briefly dip not just to zero, but into negative territory, reaching at one point negative $8.52 per megawatt hour. Why? A combination of being an "electricity island" with only weak ties to the surrounding state's grids; strong wind in a state that's sprouted thousands of windmills; and infrastructure design that means the only real buyer for most electricity producers' output is ERCOT, the Electric Reliability Council of Texas. (One of the comments attached to the story notes that Texas is not completely isolated from the national grid, but it's still markedly isolated.) A slice: Demand fell—at 4 a.m., the amount of electricity needed in the state was about 45 percent lower than the evening peak. The wind was blowing consistently—much later in the day Texas would establish a new instantaneous wind generation record. At 3 a.m., wind was supplying about 30 percent of the state’s electricity, as this daily wind integration report shows. And because the state is an electricity island, all the power produced by the state’s wind farms could only be sold to ERCOT, not grids elsewhere in the country.

APIs, Not Apps: What the Future Will Be Like When Everyone Can Code
An anonymous reader writes: There's been a huge push over the last few years to make programming part of the core academic curriculum. Hype or not, software developer Al Sweigart takes a shot at predicting what this will be in a future where some degree of coding skill is commonplace and he has an interesting take on it: "More programmers doesn't just mean more apps in app stores or clones of existing websites. Universal coding literacy doesn't increase the supply of web services so much as increase the sophistication in how web services are used. Programming—by which I mean being able to direct a computer to access data, organize it, and then make decisions based on it— will open up not only a popular ability to make more of online services, but also to demand more.
Almost every major website has an Application Program Interface (API), a formal specification for software to retrieve data and make requests similar to human-directed browsers. ... The vast majority of users don't use these APIs—or even know what an API is—because programming is something that they've left to the professionals. But when coding becomes universal, so will the expectation that websites become accessible to more than just browsers." -
Ex-Ashley Madison CTO Threatens Libel Suit Against Journalist
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.
