RichiH writes "Most of you are the free IT staff of friends and family, just as I am. One of my largest headaches is backing up their data. What I am looking for allows for off-site storage on multiple server machines running Linux, has Linux & Windows clients that Just Work and require zero everyday effort (although a large-ish effort to set them up is just fine), allows for granular access control, is versioned and will, ideally, allow me to grab data automagically (think photo pool for your family where your mother, sister, etc., share each other's photos). This is something I've been trying to find for years, but I've never seen anything even closely resembling what I want. With the Wall Street Journal handing out its Technology Innovation Award to Cleversafe recently, I was once again reminded of this particular itch which needs scratching. Before I deploy it, I want to ask the Slashdot community for its opinion on that piece of software, and on potential alternatives. How do you solve this problem?"

Chicken_dinner writes "Engineers at Battelle have come up with a way to send data through the air at 10 Gigabits per second using point-to-point millimeter-wave technology. They used standard optical networking equipment and essentially combined two lower bandwidth signals to produce a 10Gb signal from the interference. They say the technology could replace fiber optics around large campuses or companies or even deliver high-bandwidth streaming within the home."

nerdyH writes "Dell is preparing to ship two enterprise-oriented Windows Vista notebooks with an interesting feature — a built-in TI OMAP (smartphone) processor that can power instantly into Linux. The 'Latitude ON' feature is said to offer 'multi-day' battery life, while letting users access email, the web, contacts, calendar, and so on, using the notebook's full-size screen and keyboard. I wonder if someday we'll just be able to plug our phones into our laptops, switching to the phone's processor when we need to save battery life? Or, maybe x86 will just get a lot more power-efficient. Speaking at MontaVista's Vision event today, OLPC spokesperson and longtime kernel hacker Deepak Saxena said the project is aiming for 10-20 hours of battery life during active use, on existing hardware (AMD Geode LX800 clocked at 500MHz, with 1GB of Flash and 256MB of RAM)."

arcticstoat writes with an excerpt from Custom PC: "After developing a brand new CPU architecture from the ground-up, you'd expect that Toshiba, Sony and IBM would have more uses for the Cell architecture than the PlayStation 3, and Toshiba has been quick to make use of the architecture's HD video transcoding abilities in its new Qosimo laptops. However, Leadtek is now taking Toshiba's efforts a step further by putting the chip onto a PCI-E card for desktop PCs. The WinFast PxVC1100 is based on Toshiba's SpursEngine SE1000 processor, which is a cut-down version of the Cell chip. The SpursEngine chip features four SPEs (synergistic processing elements) based on 128-bit RISC cores, along with H.264 and MPEG-2 codecs, but it doesn't contain its own CPU as the chip in the PS3 does. The chip is capable of encoding and decoding H.264, MPEG-2 and MPEG-4 video streams in hardware."

mattnyc99 writes "Honda's challenger to the Prius — the Insight hybrid that we discussed so lividly a month ago — got its official unveiling today at the Paris auto show, with insiders confirming it would be cheaper than the world's most popular 'green' car while still hitting the same fuel-efficiency range. But the hybrid-electric showdown comes in the midst of a sudden rethink by Toyota about plug-in hybrids. Apparently all the recent hype — over the production version of the Chevy Volt, plus Chrysler's new electric trio and even the cool new Pininfarina EV also unveiled today — has execs from the world's number one automaker, and alt-fuel experts, questioning how many people will really buy electric cars, whether people will really charge them at night to keep the grid clear, whether batteries will make them too expensive and more.

praps writes "In a fascinating interview with two of the founders of The Pirate Bay entitled 'Are they baby-eating monsters or what?,' Swedish news site The Local discovers that far from being the radical Robin Hoods of the digital age, Peter Sunde and Fredrik Neij are actually 'polite, humorous and down-to-earth.' They may run one of the biggest sites in the world but 'it's just a hobby that's grown to be very, very large.' Financially, they are 'happy as long as it doesn't make a loss,' and both hold down regular IT day jobs. And apparently they spend a lot of time with a Bedouin in the Sinai desert."

Many readers have written to tell us that researchers are examining the possibility of using Brownian ratchets to help combat the problem of heat dissipation in miniaturized electronics. "Currently, devices are engineered to operate near thermal equilibrium, in accordance with the Second Law of Thermodynamics which states that heat tends to transfer from a hotter unit to a cooler one. However, using the concept of Brownian ratchets, which are systems that convert non-equilibrium energy to do useful work, the researchers hope to allow computers to operate at low power levels, and harness power dissipated by other functions. 'The main quest we have is to see if by departing from near-equilibrium operation, we can perform computation more efficiently,' Ghosh told iTnews. 'We aren't breaking the Second Law — that's not what we are claiming,' he said. 'We are simply re-examining its implications, as much of the established understanding of power dissipation is based on near-equilibrium operation.'"

Slatterz writes "Toshiba has unveiled a battery prototype that offers a 90 percent charge capacity in just 10 minutes. The Super Charge Ion Battery (SCIB) is capable of handling 5,000 to 6,000 recharge cycles, compared to the typical 500 offered by standard lithium-ion batteries. The new battery is composed of a durable material that offers a high level of thermal stability and prevents overheating."

For the last 10 years, I have been asking people more knowledgeable than I, "How big should my swap be?" and the answer has always been "Just set it to twice your RAM and forget about it." In the old days, it wasn't much to think about — 128 megs of RAM means 256 megs of swap. Now that I have 4 gigs of RAM in my laptop, I find myself wondering, "Is 8 gigs of swap really necessary?" How much swap does the average desktop user really need? Does the whole "twice your RAM" rule still apply? If so, for how much longer will it likely apply? Or will it always apply? Or have I been consistently misinformed over the last 10 years?

ds writes "Apple, this morning, announced they are dropping the iPhone Developer NDA in respect to released software. Previously, iPhone developers were legally bound even after their software had been released." Another reader adds, "Early release software is still covered, but this should bring about increased developer interaction, as well as a slew of iPhone dev books." The complete message about the NDA change can be seen for now at Apple's iPhone Developer site, and is reproduced below.

schliz writes "A new technique developed by HP Labs and Rice University could lower the cost of identifying 'dead zones' in large wireless networks. The technique '[combines] wireless signal models with publicly-available information about basic topography, street locations, and land use.' This enables Wi-Fi architects to test and refine their layouts cheaply before a network is deployed by focusing measurement efforts on areas that potentially could be dead zones. The technique requires only about one-fifth as many measurements as a grid sampling strategy."

ruphus13 writes "Time-shifting via Tivo changed the way we consume television programming. Now, Open Source enters the fray. Roku, the streaming-media set-top box has decided to Open Source its software. Roku had received praise for its streaming solution, and was in the press recently for its deal with Netflix, allowing users to stream Netflix movies directly to the box. From the article, 'Roku will release an open source version of its software by the end of the year. The CEO says he's looking for deals with content providers to stream their products through his device, and hopes to sell a bunch of them as a result.'"

GMGruman writes "Carriers have promised WiMax networks for years. But will they deliver the goods, or be slow like many early 3G networks or patchy in coverage like the metro Wi-Fi attempts in most cities? This hands-on review looks at a nearly-WiMax deployment (technically, OFDM) in Reno, testing its speeds and reach, as a measure of what Sprint and Clearwire will deliver in their joint WiMax rollouts starting next month. The good news is that this time, the carrier promises look to be delivered on."

Ruler of Planets writes "PlanetX64 has just published an article on loading OS X on an MSI Wind, effectively creating a machine that is smaller and lighter than a Macbook Air.

Seor Jojoba writes "The release of T-Mobile's G1 Smartphone is shifting focus away from push-based barcode scanning, where embedded URLs send you to locations of a vendor's choosing. There is now more interest in pull-scanning, where product information is retrieved from user-specified sources. It may be that QR-Codes and other 2D barcodes will have their thunder stolen by 1970s-era linear barcodes. On the iPhone, scanning a 1D barcode is slow and unreliable. But the G1's improved optics and Android's improved access to image scans has made 1D scanning quick and useful, opening the gateway for killer apps that help people make spending decisions."

Jawdy writes "I am currently leading a small game development project with artists and developers scattered all over the country. Getting together is somewhat difficult, but we try to do this every couple of months. We often share all kinds of documents with each other, and even do so while using IM clients (GTalk and MSN), but this winds up being a tedious process of: send document; read and edit; send back; rinse and repeat. What I wanted to ask fellow slashdotters is, if anyone knows of any FOSS software that can handle IM (or even voice chat), Whiteboard and document sharing — where we can all see the document, pass around 'editing rights' and edit live. Even several small apps that handle the individual components would help out!"

Harden writes "TrustedReviews has an interesting take on what the 'Ultimate Netbook' ought to be. From the article: 'How to solve a problem like the netbook? To my mind, despite nearly every manufacturer taking a stab at the thing, none has yet quite distilled my idea of what the Ultimate Netbook would be. This is partly because, until recently, not everyone had a clear understanding of what a netbook was meant to do, but also because manufacturers have all been far too busy jostling for market share to put a lot of thought into the finer details.' What would your Ultimate Netbook include?"
