Microsoft Lost a City Because They Used Wikipedia Data

“Microsoft can’t tell North from South on Bing Maps, ” joked The Register, reporting that Microsoft’s site had “misplaced Melbourne, the four-million-inhabitant capital of the Australian State of Victoria.” Long-time Slashdot reader RockDoctor writes: Though they’re trying to minimise it, the recent relocation of Melbourne Australia to the ocean east of Japan in Microsoft’s flagship mapping application is blamed on someone having flipped a sign in the latitude given for the city’s Wikipedia page. Which may or may not be true. But the simple stupidity of using a globally-editable data source for feeding a mapping and navigation system is … “awesome” is (for once) an appropriate word. Well, it’s Bing, so at least no-one was actually using it. “Bing’s not alone in finding Australia hard to navigate, ” reports The Register. “In 2012 police warned not to use Apple Maps as it directed those seeking the rural Victorian town of Mildura into the middle of a desert.” Read more of this story at Slashdot.

New Ransomware Poses As A Windows Update

Slashdot reader MojoKid quotes an article from Hot Hardware: A security researcher for AVG has discovered a new piece of ransomware called Fantom that masquerades as a critical Windows update. Victims who fall for the ruse will see a Windows screen acting like it’s installing the update, but what’s really happening is that the user’s documents and files are being encrypted in the background… The scam starts with a pop-up labeled as a critical update from Microsoft. Once a user decides to apply the fake update, it extracts files and executes an embedded program called WindowsUpdate.exe… As with other EDA2 ransomware, Fantom generates a random AES-128 key, encrypts it using RSA, and then uploads it to the culprit. From there, Fantom targets specific file extensions and encrypts those files using AES-128 encryption… Users affected by this are instructed to email the culprit for payment instructions. While the ransomware is busy encrypting your files, it displays Microsoft’s standard warning about not turning off the computer while the “update” is in progress. Pressing Ctrl+F4 closes that window, according to the article, “but that doesn’t stop the ransomware from encrypting files in the background.” Read more of this story at Slashdot.

Strange galaxy is made almost entirely of dark matter

A galaxy isn’t big just because it has many stars in it. A worldwide research group has discovered that a galaxy in the Coma cluster, Dragonfly 44, consists of 99.99 percent dark matter . It has about as much mass as our own Milky Way galaxy, but far fewer stars. The team determined the presence of the invisible, mysterious substance based on the motions of the stars themselves — there were too few of them to be moving so quickly. If there weren’t a gravitational force like dark matter to hold them together, those stars would simply fly away. Dragonfly 44 raises more questions than it solves right now. The team’s Roberto Abraham tells Wired that it’s unclear as to how a dark matter galaxy on this scale could form. Previous examples were much smaller. It’s possible that the formations of the stars (very dense clusters) are a clue, but that’s as far as astronomers can go right now. The hope is that someone will find a similar galaxy closer to home, increasing the chances of finding a dark matter particle and making some sense out a baffling (but virtually ubiquitous) aspect of the universe.

On Saturday Juno flew to within 4,200km of Jupiter—and survived

Enlarge / Jupiter’s north polar region as Juno was This view of Jupiter was taken on August 27, when Juno was 703,000km away, and closing fast. (credit: NASA/JPL-Caltech/SwRI/MSSS) NASA’s daring Juno spacecraft must fly into the heart of Jupiter’s deadly radiation belts to complete its mission. So far, so good. On Saturday morning, the spacecraft made its first close approach to Jupiter, flying to within 4,200km of the giant of the Solar System. That is less than the distance from New York to Los Angeles. The spacecraft shot past Jupiter at the speed of 208,000km/hr relative to the planet, and mission managers pronounced that Juno was in good health. “Early post-flyby telemetry indicates that everything worked as planned and Juno is firing on all cylinders,” said Rick Nybakken, Juno project manager at NASA’s Jet Propulsion Laboratory in Pasadena, California. Saturday’s flyby, at 9:44am ET, marked the first time Juno had activated its entire complement of nine scientific instruments and turned them toward Jupiter. Mission managers said early returns from the data were promising, but cautioned it would take several more days to download all of the information collected by the spacecraft, and to begin to assess what it means. Although photography is not the principal aim of the mission, NASA intends to release images taken during the flyby during the next week or so. The pictures are expected to include the highest-ever resolution views of Jupiter’s atmosphere, and the first good views of both the gas giant’s poles. Read 2 remaining paragraphs | Comments

Floating Solar Device Boils Water Without Mirrors

An anonymous reader quotes a report from Ars Technica: Researchers from MIT and the Masdar Institute of Science and Technology, led by George Ni, describe a prototype design that boils water under ambient sunlight. Central to their floating solar device is a “selective absorber” — a material that both absorbs the solar portion of the electromagnetic spectrum well and emits little back as infrared heat energy. For this, the researchers turn to a blue-black commercial coating commonly used in solar photovoltaic panels. The rest of the puzzle involves further minimizing heat loss from that absorber, either through convection of the air above it or conduction of heat into the water below the floating prototype. The construction of the device is surprisingly simple. At the bottom, there is a thick, 10-centimeter-diameter puck of polystyrene foam. That insulates the heating action from the water and makes the whole thing float. A cotton wick occupies a hole drilled through the foam, which is splayed and pinned down by a square of thin fabric on the top side. This ensures that the collected solar heat is being focused into a minute volume of water. The selective absorber coats a disc of copper that sits on top of the fabric. Slots cut in the copper allow water vapor from the wick to pass through. And the crowning piece of this technological achievement? Bubble wrap. It insulates the top side of the absorber, with slots cut through the plastic to let the water vapor out. Tests in the lab and on the MIT roof showed that, under ambient sunlight, the absorber warmed up to 100 degrees Celsius in about five minutes and started making steam. That’s a first. The study has been published in two separate Nature articles: “Steam by thermal concentration” and “Steam generation under one sun enabled by a floating structure with thermal concentration.” Read more of this story at Slashdot.

Stretching the limit of silicon nanowires for next-generation electronics

Enlarge / A forest of false-colored silicon nanowires. Flexible electronics, which could be used to  control flexible robots , depend on the ability to produce electrical circuits that can be repeatedly stretched and bent while remaining operational. Silicon is obviously one of the most important building blocks of modern electronics, but even when it’s shaped into wires, it isn’t very stretchy. Recently, theoretical calculations have indicated that it may be possible to stretch silicon nanowire by as much as 23 percent, depending on its structure and the stretch direction. This raises an obvious question: why haven’t we been able to do so? Recently, an international team of scientists and engineers have directly probed the elastic strain limit of single-crystalline Si nanowires. The team found that stretching the Si nanowires almost to their theoretical limit is possible.

Dyson Will Spend $1.4 Billion, Enlist 3,000 Engineers To Build a Better Battery

An anonymous reader quotes a report from Digital Trends: Among the 100 new products the company founder James Dyson wants to invent by 2020, the greatest investment in people and money is to improve rechargeable lithium-ion batteries, as reported by Forbes (Warning: paywalled). And Dyson is not planning incremental improvements. His opinion is that current Li-ion batteries don’t last long enough and aren’t safe enough — the latter as evidenced by their propensity to spontaneously catch on fire, which is rare but does happen. Dyson believes the answer lies in using ceramics to create solid-state lithium-ion batteries. Dyson says he intended to spend $1.4 billion in research and development and in building a battery factory over the next five years. Last year Dyson bought Ann Arbor, Michigan-based Sakti3, which focuses on creating advanced solid-state batteries, for $90 million. The global lithium-ion battery market accounts for $40 billion in annual sales, according to research firm Lux as cited by Forbes. Dyson’s company (which is an accurate description since he has 100-percent ownership) currently employs 3, 000 engineers worldwide. He intends to hire another 3, 000 by 2020. Their average age is 26. Dyson values young engineers, saying, “The enthusiasm and lack of fear is important. Not taking notice of experts and plowing on because you believe in something is important. It’s much easier to do when you’re young.” Read more of this story at Slashdot.

Ubuntu Linux 16.10 ‘Yakkety Yak’ Beta 1 Now Available For Download

An anonymous reader quotes a report from BetaNews: Today, the first beta of Ubuntu Linux 16.10 sees release. Once again, a silly animal name is assigned, this time being the letter “Y” for the horned mammal, “Yakkety Yak.” This is also a play on the classic song “Yakety Yak” by The Coasters. Please be sure not to “talk back” while testing this beta operating system! “Pre-releases of the Yakkety Yak are not encouraged for anyone needing a stable system or anyone who is not comfortable running into occasional, even frequent breakage. They are, however, recommended for Ubuntu flavor developers and those who want to help in testing, reporting and fixing bugs as we work towards getting this bos grunniens ready. Beta 1 includes a number of software updates that are ready for wider testing. These images are still under development, so you should expect some bugs, ” says Set Hallstrom, Ubuntu Studio project lead. He adds: “While these Beta 1 images have been tested and work, except as noted in the release notes, Ubuntu developers are continuing to improve the Yakkety Yak. In particular, once newer daily images are available, system installation bugs identified in the Beta 1 installer should be verified against the current daily image before being reported in Launchpad. Using an obsolete image to re-report bugs that have already been fixed wastes your time and the time of developers who are busy trying to make 16.10 the best Ubuntu release yet. Always ensure your system is up to date before reporting bugs.” Here are the following download links: Lubuntu, Ubuntu GNOME, Ubuntu Kylin, Ubuntu MATE, Ubuntu Studio.
