Lucas123 writes: A company in China has used additive manufacturing to print 10 single-room buildings out of recycled construction materials in under a day as offices for a Shanghai industrial park. The cost: about $5,000 each. The company, Suzhou-based Yingchuang New Materials, used four massive 3D printers supplied by the WinSun Decoration Design Engineering Co. Each printer is 20 feet tall, 33 feet wide and 132 feet long. Like their desktop counterparts, the construction-grade 3D printers use fused deposition modeling (FDM), where instead of thermoplastics layer after layer of cement is deposited atop one another. The cement contains hardeners that make each layer firm enough for the next. Yingchuang's technique builds structures off site in a factory one wall at a time. The structures are then assembled onsite. The technique is unlike U.S.-based Contour Crafting, a company whose 3D printing technology to form the entire outer structure of buildings at once, The Yingchuang factory and research center, a 33,000 square foot building, was also constructed using the 3D printing manufacturing technique. It only took one month to construct.

MojoKid writes with news that Microsoft has announced the opening of a 'Transparency Center' at their Redmond campus, a place where governments who use Microsoft software can come to review the source code in order to make sure it's not compromised by outside agencies. (The company is planning another Transparency Center for Brussels in Belgium.) In addition, Microsoft announced security improvements to several of its cloud products: As of now, Outlook.com uses TLS (Transport Layer Security) to provide end-to-end encryption for inbound and outbound email — assuming that the provider on the other end also uses TLS. The TLS standard has been in the news fairly recently after discovery of a major security flaw in one popular package (gnuTLS), but Microsoft notes that it worked with multiple international companies to secure its version of the standard. Second, OneDrive now uses Perfect Forward Secrecy (PFS). Microsoft refers to this as a type of encryption, but PFS isn't a standard like AES or 3DES — instead, it's a particular method of ensuring that an attacker who intercepts a particular key cannot use that information to break the entire key sequence. Even if you manage to gain access to one file or folder, in other words, that information can't be used to compromise the entire account.

sciencehabit writes: "Thanks to a decade of programs geared toward giving people access to the necessary technology, by 2013 some 85% of Americans were surfing the World Wide Web. But how effectively are they using it? A new survey suggests that the digital divide has been replaced by a gap in digital readiness. It found that nearly 30% of Americans either aren't digitally literate or don't trust the Internet. That subgroup tended to be less educated, poorer, and older than the average American."

sciencehabit writes Millions of tons. That's how much plastic should be floating in the world's oceans, given our ubiquitous use of the stuff. But a new study (abstract) finds that 99% of this plastic is missing. One disturbing possibility: Fish are eating it. If that's the case, "there is potential for this plastic to enter the global ocean food web," says Carlos Duarte, an oceanographer at the University of Western Australia, Crawley. "And we are part of this food web."

An anonymous reader writes The Obama Administration is set to appoint Phil Johnson, a pharmaceutical industry executive, as the next Director of the United States Patent and Trademark Office, according to sources. The move is likely to anger patent reform advocates given Johnson's past efforts to block legislation aimed at reining in patent trolls, and in light of his positions that appear to contradict the White House's professed goal of fixing the patent system. The top job at the Patent Office has been vacant for around 18-months since the departure of previous director David Kappos in early 2013. Currently, the office is being managed by former Googler Michelle Lee, who was appointed deputy director in December. Earlier this month, Republican Senators led by Orrin Hatch (R-UT) sent a letter to President Obama that praised Lee but that also described the current USPTO management structure as "unfair, untenable and unacceptable for our country's intellectual property agency."

A phys.org article says UK researchers have made a breakthrough that could make ammonia a practical source of hydrogen for fueling cars. From the article: "Many catalysts can effectively crack ammonia to release the hydrogen, but the best ones are very expensive precious metals. This new method is different and involves two simultaneous chemical processes rather than using a catalyst, and can achieve the same result at a fraction of the cost. ... Professor Bill David, who led the STFC research team at the ISIS Neutron Source, said 'Our approach is as effective as the best current catalysts but the active material, sodium amide, costs pennies to produce. We can produce hydrogen from ammonia "on demand" effectively and affordably.'" The full paper. The researchers claim that a two-liter reaction chamber could produce enough hydrogen to power a typical sedan.

Qbertino (265505) writes I've been rummaging around on old backups and cleaning out my stuff and have once again run into my expert-like paranoid backups and keepsakes from back in the days (2001). I've got, among other things, a full set of Debian 3 CDs, an original StarOffice 6.0 CD including a huge manual in mint condition, Corel Draw 9 for Linux, the original box & CDs — yes it ran on a custom wine setup, but it ran well, I did professional design and print work with it.

I've got more of other stuff lying around, including the manuals to run it. Loki Softs Tribes 2, Kohan, Rune, and the original Unreal Tournament for Linux have me itching too. :-)

I was wondering if it would be possible to do an old 2001ish setup of a Linux workstation on some modern super cheap, super small PC (Raspberry Pi? Mini USB PC?), install all the stuff and give it a spin. What problems should I expect? VESA and Soundblaster drivers I'd expect to work, but what's with the IDE HDD drivers? How well does vintage Linux software from 2003 play with todays cheap system-on-board MicroPCs? What's with the USB stuff? Wouldn't the install expect the IO devices hooked on legacy ports? Have you tried running 10-15 year old Linux setups on devices like these and what are your experiences? What do you recommend?

An anonymous reader writes: I don't wear a watch. I never have. So, to me, the push for smart watches has always been a non-starter. But I was discussing with friends some of the features of Android Wear that Google demonstrated at the I/O conference today, and it got me wondering: what set of features would be required for a smartwatch to become viable? Obviously, this is different for everybody — millions of people wear regular watches even though they could easily pull out their phone and check the time there. Any smartwatch can also tell time, but it has advantages (apps that do other things), and disadvantages (needs charging). Clearly, there are some functions for which it's useful to have an object strapped to your wrist, even if that function could be served by the device in your pocket. Telling time is one, and lots of people use sundry fitness doo-dads to measure exercise. It makes sense to me that checking the weather forecast would fall into this category, and perhaps checking notifications. (Conversely, other functions do not translate at all, like taking photos or playing games.) Thus, two questions: if you already wear a watch, what would it take for a smartwatch to replace it? If you don't wear a watch, what features would motivate you to get one?

itwbennett writes: A group of researchers from Google, the Hong Kong University of Science and Technology and the University of Nebraska undertook a study of over 26 million builds by 18,000 Google engineers from November 2012 through July 2013 to better understand what causes software builds to fail and, by extension, to improve developer productivity. And, while Google isn't representative of every developer everywhere, there are a few findings that stand out: Build frequency and developer (in)experience don't affect failure rates, most build errors are dependency-related, and C++ generates more build errors than Java (but they're easier to fix).

hackingbear writes: Burdened with Alabama's highest unemployment rate, long abandoned by textile mills and furniture plants, Wilcox County, Alabama, desperately needs jobs. And the jobs are coming from China. Henan's Golden Dragon Precise Copper Tube Group opened a plant here last month, employing 300 locals. Chinese companies invested a record $14 billion in the United States last year, according to the Rhodium Group research firm. Collectively, they employ more than 70,000 Americans, up from virtually none a decade ago. Powerful forces — narrowing wage gaps (Chinese wages have been doubling every few years), tumbling U.S. energy prices, the rising Yuan — up 30% over the decade — are pulling Chinese companies across the Pacific. Perhaps very soon, Chinese workers will start protesting their jobs being outsourced to the cheap labor in the U.S."

An anonymous reader writes So I, like many people, want to make my own game. Outside of MATLAB, Visual Basic, and LabVIEW I have no real programming experience. I initially started with Ruby, but after doing my homework decided that if I ever wanted to progress to a game that required some power, I would basically need to learn some form of C anyway. Further digging has led me to C#. The other parts of game design and theory I have covered: I have ~8 years of CAD modeling experience including Maya and Blender; I have a semiprofessional sound studio, an idie album on iTunes, and am adept at creating sound effects/music in a wide variety of programs; I'm familiar with the setbacks and frustration involved with game development — I beta tested DotA for 9ish years; I already have my game idea down on paper (RTS), including growth tables, unit types, unit states, story-lines, etc. I've been planning this out for a year or two; I will be doing this on my own time, by myself, and am prepared for it to take a couple years to finish. The reason for listing that stuff out, is that I want people to understand that I know what I'm getting myself in to, and I'm not trying to put out a not-so-subtle "help me make a game for free lol" type of post. With all of that said, where is a good place to start (i.e., recommended books) for learning C# for game programming? I am familiar with object oriented programming, so that's a little bit of help. I'm not necessarily looking for the syntax (that part is just memorization), but more for the methodology involved. If anyone also has any suggestions for other books or information that deal with game development, I would love to hear that too. I know enough to understand that I really don't know anything, but have a good foundation to build on.
