  • Meet the Makers of an Exotic (Partially) 3-D Printed Car (2 Videos)

    Last month, in a story headlined 3D Printed Supercar Chassis Unveiled, we promised video interviews with builders Kevin and Brad "in the near future." Here they are. First, we have Kevin Czinger, Founder & CEO of Divergent Microfactories. He says the way we build cars is more important from an environmental standpoint than how we fuel them, and that the way we make cars now is a lot less efficient and a lot more expensive than it needs to be. Divergent's first demo vehicle, the Blade, is a tandem-seating 700 HP supercar its makers say does 0 - 60 in 2.5 seconds. Price? No word yet, but it's safe to assume "plenty" might be an accurate guess. In the second video, Blade project lead Brad Balzer goes into detail about how, why, and where they use 3-D printing, and explains the modular nature of their car chassis design. He says they don't need to change many parts to go from ultra-sports car to pickup truck. He also says that while Divergent Microfactories is working on cars right now, their manufacturing system can be applied to many different industries. Indeed, their long-range goal is to help people build microfactories making many different kinds of products faster, more flexibly, and for less money than it takes to make similar manufactured items today. Note: The transcript covers both videos and has a little 'bonus' material in it, too.

  • Microsoft To Launch Minecraft Education Portal For Teachers

    Mickeycaskill writes: Microsoft wants to help educators use Minecraft to teach pupils about maths, history, creative design and other subjects and skills, claiming the game is already being used in classrooms in the US and UK. Minecraft developer Mojang was bought by Microsoft last year for $2.5 billion and the game has been featured in a number of HoloLens demos, an indication of how it sees the former indie phenomenon as more than just a game. "Very soon after Minecraft launched, we noticed teachers bringing the game into their classrooms," said a blog post. "Often inspired by the passion of their students, they started using Minecraft to design history lessons, teach language classes, explore mathematics, physics, computer science, writing, and more."

  • Google Apologises For Photos App's Racist Blunder

    Mark Wilson writes: Google has issued an apology after the automatic tagging feature of its Photos apps labeled a black couple as "gorillas". This is not the first time an algorithm has been found to have caused racial upset. Earlier in the year Flickr came under fire after its system tagged images of concentration camps as sports venues and black people as apes. The company was criticized on social networks after a New York software developer questioned the efficacy of Google's algorithm. Accused of racism, Google said that it was "appalled" by what had happened, branding it as "100% not OK".

  • Pew Survey Documents Gaps Between Public and Scientists

    PvtVoid writes: A new Pew Research Study documents an alarming gap between public perception of scientific issues and the opinions of the scientists themselves, as measured by a poll of AAAS scientists. Even worse, the gap is partisan, with clear differences between Republicans and Democrats, and between conservatives and liberals. For example, while 98% of AAAS members agree with the statement that "Human beings and other living things have evolved over time", only 21% of conservatives agree, compared with 54% of liberals. Global warming, similarly, shows an ideological gap: 98% of AAAS scientists agreed with the statement that "the Earth is getting warmer mostly due to human activity", compared with 21% of conservatives and 54% of liberals. Encouragingly, almost everybody thinks childhood vaccines should be required (86% of AAAS members, 65% of conservatives, and 74% of liberals.) Go here for an interactive view of the data.

  • 18 Years On, Ultima Online Is Still Going

    An anonymous reader writes: Ultima Online was released in September, 1997. It was the game that popularized graphical MMOs, and somehow, it's still running. Rock, Paper, Shotgun took a dive into the game to see how much it's changed, and who still plays it. As the community has shrunk, it's become increasingly tight-knit, and giving up the game now means giving up a social circle for many players. Even though newer MMOs have eclipsed the game's functionality, UO has a dedication to the full adventuring experience that later games haven't replicated. From the article: "While initially I couldn't understand the appeal of Ultima, when I decided to shake off the limitations of an early level character and simply explore for myself, I found a game world with a lot to offer. Player created civilizations, unique monsters, and the sheer mystery of the world combine to keep this ancient MMO compelling. For all the ways in which the genre has improved, Ultima Online remains one of just a few MMOs that let you live an alternative life. That feeling of ownership ... combined with the diversity on offer, keeps players coming back day after day."

  • Ask Slashdot: Getting My Wife Back Into Programming After Long Maternity Leave?

    An anonymous reader writes: My wife has been on a maternity leave for three years, now. She is starting to think about refreshing her coding skills and looking for a job. Before, she worked as a Java developer for around two years doing mostly Java Enterprise stuff. However, she is not very eager to go back to coding. I think she has the right mental skills to be a developer, but she is just not very passionate about coding or IT in general. On the other hand, it's relatively easier to find a job in IT than starting a new career. We live in Spain, and with the current economic situation, the market for software developers is not great — but it's definitely better than other jobs. I there anything else she might do, ideally Java (but could be anything IT related) that would be easier and more fun than the typical Java Enterprise stuff, while also giving her a good change to find a decent job? (I'm a Java developer myself with many years of experience but mostly doing boring Java Enterprise stuff.)

  • NASA To Waste $150 Million On SLS Engine That Will Be Used Once

    schwit1 writes: NASA's safety panel has noticed that NASA's SLS program either plans to spend $150 million human-rating a rocket engine it will only use once, or will fly a manned mission without human-rating that engine. "The Block 1 SLS is the 'basic model,' sporting a Delta Cryogenic Second Stage (DCSS), renamed the Interim Cryogenic Propulsion System (ICPS) for SLS. The current plan calls for this [interim] stage to be used on [the unmanned] Exploration Mission -1 (EM-1) and [manned] Exploration Mission -2 (EM-2), prior to moving to the [Exploration Upper Stage] — also to be built by Boeing — that will become the workhorse for SLS. However, using the [interim upper stage] on a crewed mission will require it to be human rated. It is likely NASA will also need to fly the [Exploration Upper Stage] on an unmanned mission to validate the new stage ahead of human missions. This has been presenting NASA with a headache for some time, although it took the recent ASAP meeting to finally confirm those concerns to the public." NASA doesn't have the funds to human-rate it, and even if they get those funds, human-rating it will likely cause SLS's schedule to slip even more, something NASA fears because they expect the commercial manned ships to be flying sooner and with increasing capability. The contrast — a delayed and unflown and very expensive SLS vs a flying and inexpensive commercial effort — will not do SLS good politically. However, if they are going to insist (properly I think) that SpaceX and Boeing human-rate their capsules and rockets, then NASA is going to have to hold the SLS to the same standard.

  • Where Facebook Stores 900 Million New Photos Per Day

    1sockchuck writes: Facebook faces unique storage challenges. Its users upload 900 million new images daily, most of which are only viewed for a couple of days. The social network has built specialized cold storage facilities to manage these rarely-accessed photos. Data Center Frontier goes inside this facility, providing a closer look at Facebook's newest strategy: Using thousands of Blu-Ray disks to store images, complete with a robotic retrieval system (see video demo). Others are interested as well. Sony recently acquired a Blu-Ray storage startup founded by Open Compute chairman Frank Frankovsky, which hopes to drive enterprise adoption of optical data storage.

  • Scientist Union's Talks Stall Over Pay

    HughPickens.com writes: The Sacramento Bee reports that the labor contract between California's state government and the 2,800 employees represented by the California Association of Professional Scientists expired this week, spotlighting yet again the long-running feud over whether the tiny union's members should earn as much as their peers in federal and local governments and private industry. "It's a challenge to keep people motivated," says Rita Hypnarowski. "We talk about retaining the best and the brightest, but I can see that's not going to happen." A recent survey by the Brown administration found that the total compensation for half of state-employed chemists is less than $8,985 per month ($5,715 in salary, plus $3,270 in benefit costs). That's 33 percent less than the median total compensation for federal chemists, nearly 13 percent less than the midpoint for local-government chemists and almost 6 percent below the private sector. Members of the union perform a wide variety of tasks, everything from fighting food-borne illnesses to mopping up the Refugio State Beach oil spill. For example, Cassandra McQuaid left a job last year at the Department of Public Health's state-of-the-art Richmond laboratories where she tracked foodborne illnesses. It's the kind of vital, behind-the-scenes work that goes unnoticed until an E. coli outbreak makes headlines and local health officials need a crack team of scientists to unravel how it happened. "It really came down to money," says McQuaid. "I just couldn't live in the Bay Area on a state salary."

  • Struggling University of Phoenix Lays Off 900

    An anonymous reader writes: The struggles facing for-profit colleges continue. The University of Phoenix announced poor quarterly earnings yesterday, and the institution has laid off 900 workers since September. Enrollment is down 14% since last year, and the CEO of its parent company, Apollo Education Group, says enrollment is likely to drop from 206,000 to about 150,000 next year. Apollo's stock has lost more than half its value since the beginning of the year. "Tighter regulations on for-profits and the Obama administration's push to make community college free top the list of headwinds. And non-profit universities have entered the online education space, where for-profit schools once held center stage."

  • People Are Obtaining Windows 7 Licenses For the Free Windows 10 Upgrade

    jones_supa writes: Windows 7 has quickly started increasing its market share of desktop operating systems, nearing 61%. If you're wondering why this is happening when Windows 10 is almost here, the reason is this: Windows 10 will be available as a free upgrade for those running Windows 7 and 8, and the new OS will have the exact same hardware requirements as its predecessor, so the majority of PCs should be able to run it just as well. Because Windows 7 was launched in 2009, a license is more affordable than for Windows 8, so many users are switching to this version to take advantage of the Windows 10 free upgrade offer.

  • Amazon's New SSL/TLS Implementation In 6,000 Lines of Code

    bmearns writes: Amazon has announced a new library called "s2n," an open source implementation of SSL/TLS, the cryptographic security protocols behind HTTPS, SSH, SFTP, secure SMTP, and many others. Weighing in at about 6k lines of code, it's just a little more than 1% the size of OpenSSL, which is really good news in terms of security auditing and testing. OpenSSL isn't going away, and Amazon has made clear that they will continue to support it. Notably, s2n does not provide all the additional cryptographic functions that OpenSSL provides in libcrypto, it only provides the SSL/TLS functions. Further more, it implements a relatively small subset of SSL/TLS features compared to OpenSSL.

  • How Verizon Is Hindering NYC's Internet Service

    Cuillere writes: Verizon promised to make FiOS available to all New York City residents. The deadline passed a year ago, and many residents still don't have FiOS as an option, but Verizon claims to have done its part. "The agreement required Verizon to 'pass' homes with fiber (not actually connect them), but no one wrote down in the agreement what they thought 'pass' meant. (Verizon’s interpretation, predictably, is that it doesn’t have to get very close.)" The situation is a mess, and the city isn't having much luck fighting it in the courts. Susan Crawford offers a solution: set up wholesale fiber access for third party ISPs and absolve Verizon of customer service responsibility.

  • MIT's Bitcoin-Inspired 'Enigma' Lets Computers Mine Encrypted Data

    Guy Zyskind, Oz Nathan, and the MIT Media Lab have developed a system to encrypt data in a way that it can still be shared and used without being decrypted. "To keep track of who owns what data—and where any given data’s pieces have been distributed—Enigma stores that metadata in the bitcoin blockchain, the unforgeable record of messages copied to thousands of computers to prevent counterfeit and fraud in the bitcoin economy." Enigma needs a fairly large base of users to operate securely, so its creators have proposed requiring a fee for anyone who wants data processed in this way. That fee would then be split among the users doing the processing. Those with encrypted datasets on the Enigma network could also sell access to datamining operations without letting the miners see the unencrypted data.
