ErnieKey writes A major application of 3d printing that could revolutionize space travel would be using 3d printers to create structures on non-terrestrial bodies like the moon, other planets, and even asteroids. Researchers from NASA's Kennedy Space Center have been working to develop solutions to materials issues, and recently presented initial findings on the potential for using in-situ materials like basalt for 3D printing. Their innovative method is based on only using in-situ supplies, and not materials that need to be brought into space.
MassDosage writes "At the the risk of exposing my age I remember building my first website using a rudimentary Unix text editor (Joe) and carefully handcrafting the Hypertext Markup Language (HTML) while directly logged on to the web server it was being served from. Back then Cascading Style Sheets (CSS) weren't even a glint in the eyes of their creators. A lot has changed and there's now a world of fancy WYSIWYG web page editors to choose from as well as Content Management Systems that allow you to create websites without looking at the underlying code at all. While this is all very useful and allows less technical people to create websites I still feel that having at least some knowledge of how everything works under the hood is empowering — especially in situations where you want to go beyond the limits placed on you by a certain tool. This is where Build Your Own Website: A comic guide to HTML, CSS and Wordpress comes into the picture. Its aim is to enable people new to web development to learn the subject by teaching the fundamentals of HTML and CSS first and only then describing how to use a Content Management System (CMS) — in this case Wordpress. While Wordpress might not be everyone's kettle of fish it's a good choice as an example of a modern CMS that is easily accessible and very popular. The concepts presented are simple enough that it should be easy enough for a reader to apply them to a different CMS should they want to. Read below for The rest of MassDosage's review.
anguyen8 writes Deep neural networks (DNNs) trained with Deep Learning have recently produced mind-blowing results in a variety of pattern-recognition tasks, most notably speech recognition, language translation, and recognizing objects in images, where they now perform at near-human levels. But do they see the same way we do? Nope. Researchers recently found that it is easy to produce images that are completely unrecognizable to humans, but that DNNs classify with near-certainty as everyday objects. For example, DNNs look at TV static and declare with 99.99% confidence it is a school bus. An evolutionary algorithm produced the synthetic images by generating pictures and selecting for those that a DNN believed to be an object (i.e. "survival of the school-bus-iest"). The resulting computer-generated images look like modern, abstract art. The pictures also help reveal what DNNs learn to care about when recognizing objects (e.g. a school bus is alternating yellow and black lines, but does not need to have a windshield or wheels), shedding light into the inner workings of these DNN black boxes.
Nerval's Lobster writes Back in the day, Microsoft viewed open source and Linux as a threat and did its best to retaliate with FUD and patent threats. And then a funny thing happened: Whether in the name of pragmatism or simply marketing, Microsoft began a very public transition from a company of open-source haters (at least in top management) to one that's embraced some aspects of open-source computing. Last month, the company blogged that .NET Core will become open-source, adding to its previously open-sourced ASP.NET MVC, Web API, and Web Pages (Razor). There's no doubt that, at least in some respects, Microsoft wants to make a big show of being more open and supportive of interoperability. The company's even gotten involved with the .NET Foundation, an independent organization designed to assist developers with the growing collection of open-source technologies for .NET. But there's only so far Microsoft will go into the realm of open source—whereas once upon a time, the company tried to wreck the movement, now it faces the very real danger of its whole revenue model being undermined by free software. But what's Microsoft's end-goal with open source? What can the company possibly hope to accomplish, given a widespread perception that such a move on its part is the product of either fear, cynicism, or both?
theodp writes "Investors have poured over $2 billion into businesses built on Hadoop," writes the WSJ's Elizabeth Dwoskin, "including Hortonworks Inc., which went public last week, its rivals Cloudera Inc. and MapR Technologies, and a growing list of tiny startups. Yet companies that have tried to use Hadoop have met with frustration." Dwoskin adds that Hadoop vendors are responding with improvements and additions, but for now, "It can take a lot of work to combine data stored in legacy repositories with the data that's stored in Hadoop. And while Hadoop can be much faster than traditional databases for some purposes, it often isn't fast enough to respond to queries immediately or to work on incoming information in real time. Satisfying requirements for data security and governance also poses a challenge."
cartechboy writes We've all been there, driving down a city street and we miss that pedestrian or bicycle because they are in our blind spot. Not the blind spot behind us, but covered up by the A-pillar on your vehicle. This is a growing concern as pillars and cars in general bulk up to meet new, ever stricter safety standards. Now Jaguar and Land Rover might have come up with a solution that eliminates the risk: transparent pillars. Imagine having zero blinds spots as you pull up to that intersection. No concerns about not seeing something or someone that's hidden by that large A-pillar. The technology is called 360 Virtual Urban Windscreen and it provides a 360-degree view out of the vehicle. How does it work? Essentially, a screen embedded in the surface of each pillar inside the car relays a live video feed from cameras covering the angles outside the car. To avoid overloading the driver the screens are off in default mode, and are only activated automatically when the driver uses a turn signal or checks over their head to switch lanes. While there's zero mention of when this tech will go into production, it's clear, this is the future and it's crazy.
An anonymous reader writes The Pirate Bay's crew have remained awfully quiet on the recent raid in public, but today Mr 10100100000 breaks the silence in order to get a message out to the world. In a nutshell, he says that they couldn't care less, are going to remain on hiatus, and a comeback is possible. In recent days mirrors of The Pirate Bay appeared online and many of these have now started to add new content as well. According to TPB this is a positive development, but people should be wary of scams. Mr 10100100000 says that they would open source the engine of the site, if the code "wouldn't be so s****y". In any case, they recommend people keeping the Kopimi spirit alive, as TPB is much more than some hardware stored in a dusty datacenter.
szczys writes Obviously the personal computer revolution was world-wide, but the Eastern Bloc countries had a story of PC evolution all their own. Martin Malý tells first hand of his experiences seeing black market imports, locally built clones of popular western machines, and all kinds of home-built equipment. From the article: "The biggest problem was a lack of modern technologies. There were a lot of skilled and clever people in eastern countries, but they had a lot of problems with the elementary technical things. Manufacturing of electronics parts was divided into diverse countries of Comecon – The Council for Mutual Economic Assistance. In reality, it led to an absurd situation: You could buy the eastern copy of Z80 (made in Eastern Germany as U880D), but you couldn’t buy 74LS00 at the same time. Yes, a lot of manufacturers made it, but 'it is out of stock now; try to ask next year.' So 'make a computer' meant 50 percent of electronics skills and 50 percent of unofficial social network and knowledge like 'I know a guy who knows a guy and his neighbor works in a factory, where they maybe have a material for PCBs' at those times."
Geoffrey.landis writes An article about the current California drought on 538 points out that even though global climate warming may exacerbate droughts, it's nearly impossible to attribute any particular drought to climate warming: "The complex, dynamic nature of our atmosphere and oceans makes it extremely difficult to link any particular weather event to climate change. That's because of the intermingling of natural variations with human-caused ones." They also cite a Nature editorial pointing out the same thing about extreme weather.
SydShamino writes In an effort that may run afoul of the first amendment, Sony, through their lawyer David Boies (of SCO infamy), has sent a letter to major news organizations demanding that they refrain from downloading any leaked documents, and destroy those already possessed. Sony threatens legal action to news organizations that do not comply, saying that "Sony Pictures Entertainment will have no choice but to hold you responsible for any damage or loss arising from such use or dissemination by you."
KindMind writes According to AP, Waze has caused trouble for LA residents by redirecting traffic from Interstate 405 to neighborhood side streets paralleling the interstate. From the article: "When the people whose houses hug the narrow warren of streets paralleling the busiest urban freeway in America began to see bumper-to-bumper traffic crawling by their homes a year or so ago, they were baffled. When word spread that the explosively popular new smartphone app Waze was sending many of those cars through their neighborhood in a quest to shave five minutes off a daily rush-hour commute, they were angry and ready to fight back. They would outsmart the app, some said, by using it to report phony car crashes and traffic jams on their streets that would keep the shortcut-seekers away. Months later, the cars are still there, and the people are still mad."

An anonymous reader writes "For about an hour on Friday, a few lucky Amazon UK shoppers were able to take advantage of a price glitch which discounted thousands of marketplace products to the price of 1p. An Amazon spokesman said: "We are aware that a number of Marketplace sellers listed incorrect prices for a short period of time as a result of the third party software they use to price their items on Amazon.co.uk. We responded quickly and were able to cancel the vast majority of orders placed on these affected items immediately and no costs or fees will be incurred by sellers for these cancelled orders. We are now reviewing the small number of orders that were processed and will be reaching out to any affected sellers directly.""
