Is IoT a Reason To Learn C



itwbennett writes: Whether or not beginning programmers should learn C is a question that has been roundly debated on Slashdot and elsewhere. The general consensus seems to be that learning it will make you a better programmer -- and it looks good on your resume. But now there might be another reason to learn C: the rapid growth of the internet of things (IoT) could cause a spike in demand for C skills, according to Gartner analyst Mark Driver. "For traditional workloads there is no need to be counting the bytes like there used to be. But when it comes to IoT applications there is that need once again..."

Former Engineer Says Uber Is a Nightmare of Sexism; CEO Orders Urgent Investigation



An anonymous reader shares a report on The Verge: A former Uber engineer has published an explosive account of sexism and power struggles in the workplace, with allegations beginning from her very first official day with the company. The engineer, Susan Fowler (who left Uber in December and now works for Stripe), posted the account to her blog on Sunday, calling it a "strange, fascinating, and slightly horrifying story." It is indeed horrifying. Sexism is a well-documented problem in Silicon Valley, but the particulars of Fowler's account are astounding. She says problems began on day one, when her manager accosted her with details of his sex life: "In my first official day rotating on the team, my new manager sent me a string of messages over company chat. He was in an open relationship, he said, and his girlfriend was having an easy time finding new partners but he wasn't. He was trying to stay out of trouble at work, he said, but he couldn't help getting in trouble, because he was looking for women to have sex with. It was clear that he was trying to get me to have sex with him, and it was so clearly out of line that I immediately took screenshots of these chat messages and reported him to HR. When I reported the situation, I was told by both HR and upper management that even though this was clearly sexual harassment and he was propositioning me, it was this man's first offense, and that they wouldn't feel comfortable giving him anything other than a warning and a stern talking-to. Upper management told me that he "was a high performer" (i.e. had stellar performance reviews from his superiors) and they wouldn't feel comfortable punishing him for what was probably just an innocent mistake on his part. The things only get worse for Fowler. Read the full account of her story here. In the meanwhile, Uber CEO Travis Kalanick said the company would "conduct an urgent investigation" into the allegations, and promised to fire anyone who "behaves this way or thinks this is OK." Journalist Paul Carr summing up the situation, says, "Uber's ability to be on the wrong side of every moral and ethical issue is bordering on magical."

NASA Is Studying A Manned Trip Around The Moon On A 23 Billion Rocket



An anonymous reader shares a report on NASA's ongoing work on a manned trip to the moon. From the report: Without a new administrator even nominated yet, NASA's acting head Robert Lightfoot on Wednesday requested a study of whether next year's first flight of the Space Launch System rocket, billed as the most powerful NASA has built, could have a crew of astronauts. "I know the challenges associated with such a proposition," Lightfoot said in a letter to his agency, citing costs, extra work, and "a different launch date" for the planned 2018 Exploration Mission-1 (EM-1). The mission would be launched by the massive SLS, which is still in development, then boosted by a European service module to put three astronauts inside the new Orion space capsule on a three-week trip around the moon. NASA first sent three astronauts around the moon in 1968 in the Apollo 8 mission. The last astronaut to stand on the moon, the late Gene Cernan returned to Earth in 1972. The new talk of a repeat moon-circling mission, aboard an untested spacecraft, has space policy experts variously thrilled, dismissive, and puzzled. "I frankly don't quite know what to say about it," space policy expert John Logsdon of George Washington University said. Writing on NASAWatch, Keith Cowing called the study request a "Hail Mary" pass to save the life of the SLS ahead of Trump installing a budget cutter to head the space agency. The Government Accountability Office estimates the costs of SLS and its two planned launches (a second, crewed mission is planned for 2023) at $23 billion.

Samsung To Sell Refurbished Galaxy Note 7 With a Smaller Battery Says Report



According to a report via The Korean Economic Daily, Samsung is said to be putting refurbished Galaxy Note 7 handsets on sale with new batteries following the cancellation of the device late last year. The speculation suggests the smartphones could be relaunched this June. Android Authority reports: Samsung is said to be swapping the Note 7's 3,500 mAh batteries with a "3,000 to 3,200 mAh" batteries, according to The Korean Economic Daily's sources, predominately for sale in emerging markets such as India and Vietnam. The move is said to be part of Samsung's plan to recover costs from the initial device recall and avoid environmental penalties from the estimated 2.5 million or so Galaxy Note 7s it would have to dispose of. Samsung hasn't made any official announcements in this vein, but before the battery investigation concluded, a spokesperson did tell us that the company was: "Reviewing possible options that can minimize the environmental impact of the recall." Shifting refurbished units would certainly be one way to achieve that.

Tech Breakthroughs Take a Backseat in Upcoming Apple iPhone Launch



Stephen Nellis, reporting for Reuters: The new iPhone is expected to include new features such as high-resolution displays, wireless charging and 3-D sensors. Rather than representing major breakthroughs, however, most of the innovations have been available in competing phones for several years. Apple's relatively slow adoption of new features both reflects and reinforces the fact smartphone customers are holding onto their phones longer. Timothy Arcuri, an analyst at Cowen & Co, believes upwards of 40 percent of iPhones on the market are more than two years old, a historical high. That is a big reason why investors have driven Apple shares to an all-time high. There is pent-up demand for a new iPhone, even if it does not offer breakthrough technologies. It is not clear whether Apple deliberately held off on packing some of the new features into the current iPhone 7, which has been criticized for a lack of differentiation from its predecessor. Still, the development and roll-out of the anniversary iPhone suggest Apple's product strategy is driven less by technological innovation than by consumer upgrade cycles and Apple's own business and marketing needs.

Microsoft Research Developing An AI To Put Coders Out of a Job



jmcbain writes: Are you a software programmer who voted in a recent Slashdot poll that a robot/AI would never take your job? Unfortunately, you're wrong. Microsoft, in collaboration with the University of Cambridge, is developing such an AI. This software "can turn your descriptions into working code in seconds," reports MSPoweruser. "Called DeepCoder, the software can take requirements by the developer, search through a massive database of code snippets and deliver working code in seconds, a significant advance in the state of the art in program synthesis." New Scientist describes program synthesis as "creating new programs by piecing together lines of code taken from existing software -- just like a programmer might. Given a list of inputs and outputs for each code fragment, DeepCoder learned which pieces of code were needed to achieve the desired result overall." The original research paper can be read here.

Google Releases an AI Tool For Publishers To Spot and Weed Out Toxic Comments



Google today launched a new technology to help news organizations and online platforms identify and swiftly remove abusive comments on their websites. The technology, called Perspective, will review comments and score them based on how similar they are to comments people said were "toxic" or likely to make them leave a conversation. From a report on BBC: The search giant has developed something called Perspective, which it describes as a technology that uses machine learning to identify problematic comments. The software has been developed by Jigsaw, a division of Google with a mission to tackle online security dangers such as extremism and cyberbullying. The system learns by seeing how thousands of online conversations have been moderated and then scores new comments by assessing how "toxic" they are and whether similar language had led other people to leave conversations. What it's doing is trying to improve the quality of debate and make sure people aren't put off from joining in.

Scientists Discover a Way To Get Every Last Drop of Ketchup Out of the Bottle



Slashdot reader schwit1 quotes a report from BBC: Scientists in Boston have found a way to get every last drop of ketchup out of the bottle. They have developed a coating that makes bottle interiors super slippery. The coating can also be used to make it easier to squeeze out the contents of other containers, such as those holding toothpaste, cosmetics and even glue. The researchers at the Massachusetts Institute of Technology (MIT) believe that their innovation could dramatically reduce waste. In its manufacture, the container must first be coated on the inside with a rough surface. A very thin layer is then placed over this. And, finally, a liquid is added that fills in any troughs to form a very slippery surface -- like an oily floor. The ketchup hovers on top and just glides out of the bottle. According to Prof Kripa Varanasi, who developed the slippery surface, the technology is completely safe. "The cool thing about it is that because the coating is a composite of solid and liquid, it can be tailored to the product. So for food, we make the coating out of food-based materials and so you can actually eat it." schwit1 adds: "Pretty slick."

NASA Scientists Propose New Definition of Planets and Pluto Could Soon Be Back



Rei writes: After several years of publicly complaining about the "bullsh#!2$" decision at the IAU redefining what comprises a planet, New Horizons program head Alan Stern and fellow planetary geologists have put forth a new definition which they seek to make official, basing planethood on hydrostatic equilibrium. Under this definition, in addition to Ceres, Pluto and other Kuiper Belt objects, large moons like Titan and Europa, as well as our own moon, would also become planets; "planet" would be a physical term, while "moon" would be an orbital term, and hence one can have a planetary moon, as well as planets that orbit other stars or no star at all (both prohibited under the current definition). The paper points out that planetary geologists already refer to such bodies as planets, citing examples such as a paper about Titan: "A planet-wide detached haze layer occurs between 300-350 km above the surface; the visible limb of the planet, where the vertical haze optical depth is 0.1, is about 220 km above the surface."

Sony Unveils World's Fastest SD Card



At CP\+2017, Sony announced the SF-G UHS-II SD card that features read and write speeds of 300MB/s and 299 MB/s, respectively, which makes it the fastest SD card in the world. Amateur Photographer reports: Available in 32GB, 64GB or 128GB from March 2017, all versions of the cards are compatible with Sony's free file rescue software, for recovering lost content. Pricing has yet to be revealed. Alongside the SF-G series, Sony has also introduced a new memory card reader, the MRW-S1, due for release in April. It features an in-built SuperSpeed USB port for cable-free PC connection, so that your files can be copied faster than by using the slower SD slot on a PC. [From the press release:] "'As the continuous shooting of higher-resolution images and adoption of 4K video with DSLR and mirrorless camera increases, the inherent need for larger, faster and more reliable cards becomes apparent. Thanks to the SF-G series, we continue to show our commitment to providing a full range of extremely high performance media devices to professional photographers and enthusiasts, maximizing their camera performances,' said Romain Rousseau, European Product Marketing Manager."
