Philips hue: the ‘world’s smartest’ LED lightbulb that saves you time during Red Alerts

Historically, altering the lighting color of a room required draping a gossamer-thin cloth over a lamp or buying a new bulb from the store. Philips has sought to solve that most taxing of first-world problems with the hue, a smartphone-controlled LED bulb that can cycle through shades at your whim. As well as block colors, you can use photos to create palette and can control the units even when away from home. It’ll be an Apple Store exclusive from October 30th, with individual units setting you back $59 (£49, €59) and three-bulb introduction pack with a wireless bridge for $199 (£179, €199). If that seems a little steep, just console yourself in the knowledge that it’s a thousand times more useful than other lighting devices we’ve seen this year.

Penguin and Random House merge, promise a brave new e-book future

The pressure of digital transitions can lead traditional media companies to circle the wagons — for better or for worse — and book publishers certainly aren’t immune as e-books take hold. Bertelsmann and Pearson are worried enough to be merging their respective Random House and Penguin publishing wings into a joint venture, not-so-creatively titled Penguin Random House, that they hope will better survive “long-term trends” like the shift away from paper-centric business models. While the two are engaged in the usual corporatespeak of creating “synergies” (read: resource cuts), we’re more interested in talk of the union being a springboard for digital efforts: Penguin Random House wants to be “more adventurous” with e-book models like self-publishing . Whether the merger leads to a renaissance for established publishers or just reduced competition when the deal closes in the back half of 2013, we’re bracing ourselves for the possibility of a Fifty Shades of Jamie Oliver crossover.

Better on the inside: under the hood of Windows 8

Windows 8’s most obvious—and most divisive—new feature is its user interface . However, it would be a mistake to think that the user interface is the only thing that’s new in Windows 8: there’s a lot that’s changed behind the scenes, too. Just as is the case with the user interface, many of the improvements made to the Windows 8 core are motivated by Microsoft’s desire to transform Windows into an effective tablet operating system. Even those of us with no interest at all in tablets can stand to take advantage of these changes, however. For example, Windows 8 is more power efficient and uses less memory than Windows 7; while such work is critical to getting the software to run well on low-memory tablets with all-day battery life, it’s equally advantageous for laptop users. The biggest single piece of technology that is new to Windows 8 is, however, squarely Metro focused: it’s a large set of libraries and components called WinRT. I’ve already written extensively about what WinRT is, so I won’t be getting into that here, but there are system capabilities that WinRT apps can use (or are forced to use) that are interesting in their own right.

IBM prepares for end of process shrinks with carbon nanotube transistors

Carbon nanotubes sit on top of features etched in silicon. IBM Research The shrinking size of features on modern processors is slowly approaching a limit where the wiring on chips will only be a few atoms across. As this point approaches, both making these features and controlling the flow of current through them becomes a serious challenge, one that bumps up against basic limits of materials. During my visit to IBM’s Watson Research Center, it was clear that people in the company is already thinking about what to do when they run into these limits. For at least some of them, the answer would involve a radical departure from traditional chipmaking approaches, swithching from traditional semiconductors to carbon nanotubes. And, while I was there, the team was preparing a paper (now released by Nature Nanotechnology ) that would report some significant progress: a chip with 10,000 working transistors made from nanotubes, formed at a density that’s two orders of magnitude higher than any previously reported effort. During my visit to Watson, I spoke with George Tulevski, who is working on the nanotube project, and is one of the authors of the recent paper. Tulevski described nanotbues as a radical rethinking of how you build a chip. “Silicoon is a solid you carve down,” he told Ars, “while nanoubes are something you have to build up.” In other words, you can’t start with a sheet of nanotubes and etch them until you’re left with the wiring you want.

Storage Spaces explained: a great feature, when it works

Windows Home Server was never a particularly popular product, but it did bring some interesting features to the table for the few who used it and became fans. One of these features was called Drive Extender, and its claim to fame was that it allowed users to pool their system’s hard drives so that they were seen by the operating system as one large hard drive. This obviated the need to keep track of the amount of free space across several disks, and it also allowed users to automatically mirror their data to multiple disks at once, keeping their files safe in the event of drive failure. Microsoft killed Drive Extender not long before pulling the plug on the Windows Home Server entirely , but the intent behind it lives on in Windows 8’s new Storage Spaces feature: “Storage Spaces is not intended to be a feature-by-feature replacement for that specialized solution,” wrote Microsoft’s Rajeev Nagar in a blog post introducing the feature, “but it does deliver on many of its core requirements.” In essence, Storage Spaces takes most of Drive Extender’s underlying functionality and implements it in a way that is more technically sound; early versions of Drive Extender sometimes corrupted data when copying files between drives and mangled file metadata, but the underlying filesystem improvements made to support Storage Spaces should make it much more robust, at least in theory.

US Navy tests first 11-meter missile-firing sea drone (video)

Advances in unmanned military tools and vehicles have come on leaps and bounds, but, until now, we haven’t seen a weapon firing drone operating in the seas. A recent test taking part offshore near Maryland saw several missiles launched from a new remote-controlled inflatable-hulled ship. While the Navy has used drones before for mine clearing and other defensive tasks, the small boat (similar to that pictured above) is the first experiment to involve true offensive capabilities. The almost zodiac-like craft has been an ongoing project over recent years, and contains a fully automated system which the Navy calls a “Precision Engagement Module” which uses an Mk-49 mounting with a dual missile launcher manufactured by Rafael. The hope is that such vehicles could patrol the coastline, or serve as a first defense against pirates, and other such small, fast-moving seafaring dangers. If you want to catch it in action, head past the break for the video, but don’t be fooled. While it might look like a series of misses, the Navy claims this is just a trick of the camera angle, with all six missiles apparently making contact.

The Internet Archive Has Saved Over 10,000,000,000,000,000 Bytes of the Web

An anonymous reader writes “Last night, the Internet Archive threw a party; hundreds of Internet Archive supporters, volunteers, and staff celebrated that the site had passed the 10,000,000,000,000,000 byte mark for archiving the Internet. As the non-profit digital library, known for its Wayback Machine service, points out, the organization has thus now saved 10 petabytes of cultural material.” The announcement coincided with the release of an 80-terabyte dataset for researchers and, for the first time, the complete literature of a people: the Balinese.

$99 Raspberry Pi-sized “supercomputer” hits Kickstarter goal

A prototype of Parallella. The final version will be the size of a credit card. Adapteva A month ago, we told you about a chipmaker called Adapteva that turned to Kickstarter in a bid to build a new platform that would be the size of a Raspberry Pi and an alternative to expensive parallel computing platforms. Adapteva needed at least $750,000 to build what it is calling “Parallella”—and it has hit the goal. Today is the Kickstarter deadline, and the project is up to more than $830,000  with a few hours to go. ( UPDATE : The fundraiser hit $898,921 when time expired.) As a result, Adapteva will build 16-core boards capable of 26 gigaflops performance, costing $99 each. The board uses RISC cores capable of speeds of 1GHz each. There is also a dual-core ARM A9-based system-on-chip, with the 16-core RISC chips acting as a coprocessor to speed up tasks. Adapteva is well short of its stretch goal of $3 million, which would have resulted in a 64-core board hitting 90 gigaflops, and built using a more expensive 28-nanometer process rather than the 65-nanometer process used for the base model. The 64-core board would have cost $199. Read 2 remaining paragraphs | Comments
