Submission + - Dell Brings Ubuntu Linux 14.04 To XPS 13 Developer Edition Laptop (

MojoKid writes: Also known as "Project Sputnik," Dell came up with the idea of offering developers a variant of their XPS 13 notebook running Linux and launched its first models over three years ago. Now in its 5th generation, Project Sputnik is still going strong today with the latest models combining Ubuntu 14.04 with Intel's Skylake processors. To kick off its newest generation of Developer Edition laptops, Dell is offering three Core i7 XPS 13 configurations, including two that feature 16GB of RAM. Dell said it also plans to add a Core i5 option to the Developer Edition lineup sometime down the line. Dell is seeing increased interest from customers and in addition to the XPS Developer Edition, Dell offers Ubuntu on its Precision 5510, 3510, 7510, and 7710 mobile workstations, as well as its Precision M3800. Cost of entry into Developer Edition territory runs $1,550. What that gets you is a 13.3-inch QHD+ (3200x1800) InfinityEdge touch display powered by an Intel Core i5-6560U processor, 8GB of LPDDR3 1866 RAM, and Intel Iris Graphics 540.

Submission + - Vantablack: The Darkest & Blackest Material On Earth (

writes: Vantablack is the blackest material on earth. This blackest material on earth is a non-metal. Vantablack is a substance made of carbon nanotubes. Surrey NanoSystems created Vantablack in 2014. Vantablack is the darkest material ever. The company describes Vantablack as a “forest” of millions of nanotubes. When you run a laser through this material, the red dot can’t be seen anywhere. Light can’t escape through the web of nanotubes.

Submission + - Is Delphi the next Database dev platform.. again?

santakrooz writes: Delphi's always been known as a solid database application development platform, it just had it's 12th birthday on Valentines day, and now the Delphi guys are coming up with a completely new database architecture. The interesting thing is that it's backward compatible, insanely extensible, single sourced between .NET and Wintel native code, and... and written completely in Delphi. Ok I know Delphi's written in Delphi and there are "wow" apps out there written in Delphi like Skype that Delphi guys always like to mention, there was a loosely supported Linux version, so my question is, what can't you do in Delphi? Or a better question is... what have Slashdot readers written in Delphi?

Submission + - Asteroid impact threat

Maggie McKee writes: "Kamchatkans and Venezuelans beware. A 20-million-tonne asteroid could be heading your way. Californians have even more reason to worry — the asteroid is more likely to hit the Pacific Ocean, triggering a tsunami that could devastate the west coast of North America. These are among the scenarios projected for asteroid Apophis, which researchers now say has a 1 in 45,000 chance of hitting Earth on 13 April 2036. Calculations show it would strike somewhere along a narrow track that stretches eastward from Siberia to the west coast of Africa. The threat, while small, is real enough to merit a United Nations protocol for dealing with the problem, experts say."

Submission + - Videoconferencing server for Linux ?

Hymer writes: Well it is really a simple question: Does anyone here know a vidoconferencing server for Linux ? It may be a non-standard solution but the clients have to exist for at least Linux, Windows and Mac OS X. The communication channel should preferably encrypted. I need video and some kind of common workplace or desktop sharing, audio is optional. I've searched the Net and found nothing... geeks do not need to look at other geeks to understand eachother but CEO's obviously does... ;-)

Submission + - Zink Imaging to launch inkless printer

Vinit writes: "Zink Imaging has developed a unique technology which can print pictures without ink! The innovation could be applied to make hand-held printers that can be integrated into mobile phones and digital cameras. While printing one only needs a paper, I mean Zink paper which is initially colorless, looks and feels like ordinary white photograph paper and is not light sensitive. You can get a copy of picture (5 cm x 7.5 cm) in 30 seconds and the photos are are very durable — they cannot be torn and are also water resistant. The firm plans to launch two products by the end of the year: a small battery-operated, pocket-sized printer for camera-phones and a digital camera with a 2 inch x 3 inch (5 cm by 7.5 cm) printer built in. The company recently demonstrated a working prototype of the camera phone printer at the DEMO 2007 technology conference in California, US. The printer is expected to cost $200 while 100 sheets of paper will cost $20. ng_to_launch_inkless_printer.php"

A Tour of Googleplex East 109

An anonymous reader writes "In Googleplex East: Search And The City, IWeek has posted a visual tour of the search giant's NYC HQ, complete with the requisite massage room, candy machine, and funky cafeteria. (There are even — surprise — work areas.) A companion story argues that New York City has reemerged as a tech center, citing the access to the Big Apple's media as a powerful pull for Web 2.0 companies. It also argues that NY's business community is more important these days to startups than Silicon Valley's deep pool of talent. Do you buy this thesis? Isn't it really unimportant these days where you work, geographically?"

Jari Mustonen writes: Time to hide your Mac-fanboy hat. Or maybe you are beliver enough to defend Apple even on this one. The question is simple: Where is the Java 6 for OS X? Let the gossips fly and let the slashdot do what it is best at: to summon an anonymous coward from Apple to tell us what is happening and where is my Java? But in the mean time, let's hear your theory.

Submission + - Teaching the 21st Century Skills Set?

Grishknash writes: "I'm a teacher at a well known private, international high school. We recently had David Warlick present at our school about 21st century literacy. efiningLiteracyForThe21stCentury I'm also a member of the recommendation committee at the school for science curriculum on content and skills. Being a techie type guy I naturally desire technological integration and literacy in my classroom, but I keep asking myself — when, how much, what types. So I thought to ask you, the slashdotters. What do you want your children to learn in science classes and how? To what degree content vs inquiry? What are the 21st century skills your [and my] children need for 21st century success? Are they the same skills my older colleagues [problem solving, critical analysis, creativity] say they are, or have they changed in some way? Like this group suggests?"
