Solar Impulse, Continuing World-Spanning Trip, Attempts To Cross The Pacific
Posted by News Fetcher on June 28 '15 at 10:30 PM
By timothy from Slashdot's can't-find-your-bags-at-all-sir department:
The BBC reports that Solar Impulse has resumed its 'round-the-world attempt, having taken off today from Nagoya, Japan for what is intended to be a 120-hour voyage to Hawaii. [If pilot Andre Borschberg] succeeds, it will be the longest-duration solo flight in aviation history, as well as the furthest distance flown by a craft that is powered only by the Sun. The Pacific crossing is the eighth leg of Solar Impulse's journey around the world.
But this stage has proven to be the most difficult, and has been hit by weeks of delays."
The circumnavigation attempt began earlier this year.

Chromecast Update Bringing Grief For Many Users
Posted by News Fetcher on June 28 '15 at 08:15 PM
By timothy from Slashdot's everyone-complains department:
An anonymous reader writes: Last week, many Chromecast users were automatically "upgraded" to build 32904. Among the issues seen with this update are placing some users on the 'beta' release track, issues with popular apps such as Plex, HBO GO, (more embarassingly) YouTube, and others. Google so far has been slow to respond or even acknowledge the issues brought by customers, save for the beta release mishap. If you're a Chromecast user, what's been your experience?

Pass the Doritos, Scientists Develop Computer Game Targeted At Healthy Choices
Posted by News Fetcher on June 28 '15 at 04:15 PM
By timothy from Slashdot's it-puts-the-lotion-on-its-skin-or-else-it-gets-basal-cell-carcinoma department:
MojoKid writes: Psychologists at the University of Exeter and Cardiff University have published a study that demonstrates how a simple computer game can help people lose weight. Participants in the study who played the specialized game lost and average of 1.5 pounds in the first seven days, and 4.5 pounds after six months. They also reduced their daily caloric consumption by 220 calories. Dr. Natalia Lawrence led the team of researchers that developed the computer game for the study. It was designed to train people to resist unhealthy food snack foods through a "stop versus go" process. Participants sat in front of a Pentium 3 PC running Matlab software on a 17-inch monitor. They were then instructed to press certain keys when images of things like fruits and clothes would appear, indicating a "go." But for images of calorie-dense foods (chips and cake, for example) they were instructed not to do anything, indicating a "stop" action.

Ask Slashdot: For What Are You Using 3-D Printing?
Posted by News Fetcher on June 28 '15 at 03:15 PM
By timothy from Slashdot's endless-dollhouse-furniture department:
An anonymous reader writes: I've been thinking about getting a 3-D printer for a while: the quality is rising, the software is better, STL files really do seem a sufficiently good standard ("sufficiently standard," that is — I'm not worried that printers are going to stop supporting it anytime soon), and prices have dropped quite a bit. Importantly to me, it also seems like less of a jumping-off-a-cliff decision, since I can get a completely assembled one from places as wild and crazy as ... the Home Depot (not that I plan to). However, even the stretchiest practical things I can think of to print can't truly actually justify the price, and that's OK — I hope not to require enough replacement knobs and chess pieces to necessarily *need* one, and playing around with it is the main likely upshot, which I'm OK with. But still, I'd like to hear what uses you have been putting your 3-D printer to, including printers that aren't yours but belong to a hackerspace, public library, eccentric neighbor, etc. What actually practical / useful tasks have you been using 3-D printing for, and with what printer technology? What playful purposes? It's OK if you just keep printing out those chess pieces and teapots, but I'm curious about less obvious reasons to have one around. (And I might just use the local Tech Shop's anyhow, but the question still applies.) If you've purchased a 3D printer, are you happy with the experience? If so, or if not, what kind did you get?

Samsung Nanotech Breakthrough Nearly Doubles Li-Ion Battery Capacity
Posted by News Fetcher on June 28 '15 at 02:00 PM
By timothy from Slashdot's don't-worry-phone-makers-will-keep-up department:
The Korea Times reports that Samsung researchers have published in Nature Communications the results of research (here's the abstract) that could lead to vastly greater storage capacity for lithium-ion batteries. The researchers, by growing graphene on silicon anodes, were able to preserve the shape of the anodes, an outcome which has formerly eluded battery designers: silicon tends to deform over numerous charging cycles. From the linked abstract: Here we report direct graphene growth over silicon nanoparticles without silicon carbide formation. The graphene layers anchored onto the silicon surface accommodate the volume expansion of silicon via a sliding process between adjacent graphene layers. When paired with a commercial lithium cobalt oxide cathode, the silicon carbide-free graphene coating allows the full cell to reach volumetric energy densities of 972 and 700Whl1 at first and 200th cycle, respectively, 1.8 and 1.5 times higher than those of current commercial lithium-ion batteries.

BBC Curates The "Right To Be Forgotten" Links That Google Can't
Posted by News Fetcher on June 28 '15 at 12:15 PM
By timothy from Slashdot's good-on-them department:
An anonymous reader writes, quoting the BBC's Internet Blog: "Since a European Court of Justice ruling last year, individuals have the right to request that search engines remove certain web pages from their search results. Those pages usually contain personal information about individuals."

The BBC, however, is not obligated to completely censor the results, and so has taken an approach that other media outlets would do well to emulate: they're keeping a list of those pages delisted by the search engines, and making them easy to find through the BBC itself. Why?

The BBC has decided to make clear to licence fee payers which pages have been removed from Google's search results by publishing this list of links. Each month, we'll republish this list with new removals added at the top.

We are doing this primarily as a contribution to public policy. We think it is important that those with an interest in the “right to be forgotten” can ascertain which articles have been affected by the ruling. We hope it will contribute to the debate about this issue. We also think the integrity of the BBC's online archive is important and, although the pages concerned remain published on BBC Online, removal from Google searches makes parts of that archive harder to find.

Detecting Nudity With AI and OpenCV

Take one face detector from OpenCV and use it to find a nose. Take the skin color from the nose and then see what parts of the body are skin colored in the photo. If there is lot of skin color shout NUDE! Actually the website lets you put in your ow photos and classifies them into Rude or Good and gives you a confidence estimate. Obama with his top off — no problem but the familiar image processing test photo of Lena the pin up girl rates a 'Rude'.

WSJ Overstates the Case Of the Testy A.I.
Posted by News Fetcher on June 28 '15 at 10:15 AM
By timothy from Slashdot's how-do-you-feel-about-me-being-eliza department:
mbeckman writes: According to a WSJ article titled "Artificial Intelligence machine gets testy with programmer," a Google computer program using a database of movie scripts supposedly "lashed out" at a human researcher who was repeatedly asking it to explain morality. After several apparent attempts to politely fend off the researcher, the AI ends the conversation with "I'm not in the mood for a philosophical debate." This, says the WSJ, illustrates how Google scientists are "teaching computers to mimic some of the ways a human brain works."

As any AI researcher can tell you, this is utter nonsense. Humans have no idea how the human, or any other brain, works, so we can hardly teach a machine how brains work. At best, Google is programming (not teaching) a computer to mimic the conversation of humans under highly constrained circumstances. And the methods used have nothing to do with true cognition.

AI hype to the public has gotten progressively more strident in recent years, misleading lay people into believing researchers are much further along than they really are — by orders of magnitude. I'd love to see legitimate A.I. researchers condemn this kind of hucksterism.

Google Will Reduce Accidental Mobile Ad Clicks, With Mandatory Borders and More
Posted by News Fetcher on June 28 '15 at 09:00 AM
By timothy from Slashdot's next-step-per-tab-muting department:
Mark Wilson submits news that Google is throwing a bone to mobile users annoyed by ads that (accidentally, or accidentally-on-purpose) make it too easy to accidentally click, breaking your browsing flow, by making those ads a bit less clickable. Writes Beta News: The company is taking steps to make the 'user experience' of ads a little better. It recognizes that advertisements that get clicked accidentally don't benefit anybody. They end up irritating the clicker, and are unlikely to be of value to the company that placed the ad. With around half of ad clicks being made by mistake, Google is now taking steps to stop this from happening — great news for users advertisers alike. In all, Google is making three key changes to ads that appear on smartphones and tablets, starting off by adding an unclickable border to the outer edges of advertisements.

Scientists Overcome One of the Biggest Limits In Fiber Optic Networks
Posted by News Fetcher on June 28 '15 at 07:45 AM
By timothy from Slashdot's ok-everyone-this-time-together department:
Mark.JUK writes: Researchers at the University of California in San Diego have demonstrated a way of boosting transmissions over long distance fiber optic cables and removing crosstalk interference, which would mean no more need for expensive electronic regenerators (repeaters) to keep the signal stable. The result could be faster and cheaper networks, especially on long-distance international subsea cables. The feat was achieved by employing a frequency comb, which acts a bit like a concert conductor; the person responsible for tuning multiple instruments in an orchestra to the same pitch at the beginning of a concert. The comb was used to synchronize the frequency variations of the different streams of optical information (optical carriers) and thus compensate in advance for the crosstalk interference, which could also then be removed.

As a result the team were able to boost the power of their transmission some 20 fold and push data over a "record-breaking" 12,000km (7,400 miles) long fiber optic cable. The data was still intact at the other end and all of this was achieved without using repeaters and by only needing standard amplifiers.

A Failure For SpaceX: Falcon 9 Explodes During Ascension
Posted by News Fetcher on June 28 '15 at 07:00 AM
By timothy from Slashdot's harsh-news department:
MouseR writes with bad news about this morning's SpaceX launch: About 2:40 into it's flight, Falcon 9 exploded along stage 2 and the Dragon capsule, before even the stage 1 separation. Telemetry and videos are inconclusive, without further analysis as to what went wrong. Everything was green lights. This is a catastrophe for SpaceX, which enjoyed, until now, a perfect launch record.

TechCrunch has coverage of the failure, which of course also means that today's planned stage one return attempt has failed before it could start; watch this space for more links.

Disney Bans Selfie Sticks
Posted by News Fetcher on June 28 '15 at 06:00 AM
By timothy from Slashdot's because-they're-goofy department:
New submitter albimaturityr writes with a story from the Orlando Sentinel that Disney is banning selfie sticks from its parks, starting with Disney World (as of Tuesday) but continuing with its other parks in California, Paris, and Hong Kong. Says the report: The issue has been building at Disney. Previously, the sticks were prohibited from its rides, and "no selfie-sticks" signs were at select rides, such as Big Thunder Mountain Railroad at Magic Kingdom. Cast members have given verbal warnings to rule breakers.

Several incidents preceded the change, but officials have been discussing the rules for some time, Disney said. This week at Disney California Adventure park, a roller coaster was halted after a passenger pulled out a selfie-stick. The ride was closed for an hour.

Despite Regulatory Nod, Cheap Ebola Test Still Undeployed
Posted by News Fetcher on June 28 '15 at 05:00 AM
By timothy from Slashdot's but-we-can-pay-in-2017-dollars department:
According to an article in Nature, the researchers who developed an inexpensive, reliable field test for the Ebola virus are <a>frustrated by the delay they've seen</a> in actually having that test deployed. Known as the Corgenix test after the company which developed it, this diagnostic tool "could not replace lab confirmation, but it would allow workers to identify infected people and isolate them faster, greatly reducing the spread of disease," according to infectious-diseases physician Nahid Bhadelia. However, though it's been approved both by the US FDA (for emergency use) and the World Health Organization, its practical use has been hampered by country-level regulations. Just why is unclear; the test seems to be at least as effective as other typical tests, and in some ways better.
One concern was that the test might fail to detect the virus in some cases of Ebola. But the independent field-validation1 (in Sierra Leone) shows that the kit was as sensitive at catching cases as the gold-standard comparison — a real-time polymerase chain reaction (RT-PCR) test that amplifies and detects genetic sequences that are specific to Ebola in blood and other bodily fluids.

FB Reveals Woeful Diversity Numbers
Posted by News Fetcher on June 28 '15 at 03:15 AM
By timothy from Slashdot's talent-on-hand department:
theodp writes: There's more work to do," said Facebook's Global Director of Diversity Maxine Williams, who issued a straight-out-of-How-to-Lie-With-Statistics diversity update on Thursday that essentially consisted of a handful of bar charts labeled with only percentages for select measures of the social networking giant's current demographics. In search of real numbers, the Guardian turned to Facebook's most recent Equal Employment Opportunity report filing, which showed that the ranks of black employees swelled by a grand total of seven (7) (1 woman) in the year covered by the filing, during which time Facebook saw an overall headcount increase of 1,231. Comparing Facebook's new bar charts of US tech employees to those issued last year shows the proportion of Hispanic and Black employees remained flat at 3% and 1% respectively, while a decline in the proportion of white employees from 53% to 51% was offset by an increase in the proportion of Asian employees from 41% to 43%.

Genetic Rescue Efforts Could Help Coral Shrug Off Warmer Oceans
Posted by News Fetcher on June 28 '15 at 12:30 AM
By timothy from Slashdot's make-more-brain-coral department:
The Washington Post reports that research published last week in the journal Science indicates that coral reefs may be less vulnerable to ocean temperature changes than has been widely believed, especially given human intervention. A slice: Some corals already have the genes needed to adapt to higher ocean temperatures, and researchers expect those genes will naturally migrate and mix with corals under stress over time ... And that process could potentially be sped up artificially. ... Giving coral evolution a boost isn't an entirely new concept. Some scientists have already suggested genetically modifying corals through artificial breeding, or doing the same for the tiny microbes that live inside corals and are essential to reef growth.

Weather Promising for Sunday Morning SpaceX Launch
Posted by News Fetcher on June 27 '15 at 09:45 PM
By timothy from Slashdot's ask-the-north-koreans department:
USA Today reports that the weather looks good for Sunday morning's planned launch at 10:21, Florida time (14:21 GMT) of SpaceX's Dragon cargo capsule, loaded with a docking adapter intended for future manned-crew access to the International Space Station. An excerpt:

"The forecast calls for a 90% chance of weather good enough to permit SpaceX's 208-foot Falcon 9 rocket to blast off from Cape Canaveral Air Force Station during an instantaneous launch window.
... "This is actually pretty cool, because it does play right into our next Crew Dragon program," [Hans] Koenigsmann, SpaceX's vice president for mission assurance, said of the docking adapter in a separate news briefing. "It's something that we bring up for our own future, and so we're really motivated to bring this up."


Related: astroengine writes points out that as part of this launch, SpaceX will make another attempt at landing the first stage of its Falcon 9 rocket on a floating platform off the coast of Florida after sending the Dragon cargo vehicle to the International Space Station. Although SpaceX is hoping to achieve something the rocket industry has never done before (true usability of rocket engines, cutting costs), it's not the only game in town — Blue Origin, ULA and Airbus all have rocket return desires.

New submitter WarJolt writes: Apple is adding Force Touch to their iPhone 6S and iPhone 6S Plus. I'm not sure if Force Touch enough to convince an Android user like myself to switch, but there are definitely some interesting possibilities for app developers. A challenge for App developers will be to make apps compatible with both Force Touch iPhones and non-force touch iPhones. (Here's the Bloomberg report Forbes draws from.)

Aiming To Beat Tesla's "3", Chevy Tests and Teases a Cheaper 200-Mile Electric Car
Posted by News Fetcher on June 27 '15 at 03:45 PM
By timothy from Slashdot's zipping-around department:
PC Magazine is one of many to note Chevrolet's upcoming effort to beat Tesla's Model 3 to market with a car that is "affordable" (a lot more affordable than the Model S) but which tops the 200-mile range that right now only Tesla beats in a widely available pure electric car. The Model 3 is expected to feature many of the features of the currently Tesla S variants, but in a smaller package and with a much lower price tag. The linked article features GM-supplied video of Chevy's all-elecric bolt, about which it says The car maker doesn't reveal much beyond what we already know: 200-plus-mile range and a starting price tag of $30,000. The video shows various Chevy engineers putting the camouflage-wrapped Bolt EV through its paces—climbing hills, accelerating, and coming to a stop, as well as enduring extreme heat and charging.

AMD's Project Quantum Gaming PC Contains Intel CPU
Posted by News Fetcher on June 27 '15 at 02:15 PM
By timothy from Slashdot's pride-of-place department:
nateman1352 links to an article at Tom's Hardware which makes the interesting point that chip-make AMD will offer Intel -- rather than AMD -- CPUs in their upcoming high-end gaming PC. (High-end for being based on integrated components, at least.) From the article:

Recently, AMD showed off its plans for its Fiji based graphics products, among which was Project Quantum – a small form factor PC that packs not one, but two Fiji graphics processors. Since the announcement, KitGuru picked up on something, noticing that the system packs an Intel Core i7-4790K "Devil's Canyon" CPU. We hardly need to point out that it is rather intriguing to see AMD use its largest competitor's CPU in its own product, when AMD is a CPU maker itself.
