Wi-Fi Direct Overlaps Bluetooth Territory For Connecting Devices 152

Reber Is Reber writes "The Wi-Fi Alliance announced a new wireless networking specification which will enable devices to establish simple peer-to-peer wireless connections without the need for a wireless router or hotspot. Wi-Fi Direct has a wide array of potential uses, many of which encroach on Bluetooth territory and threaten to make the competing wireless protocol obsolete. 'Wi-Fi Direct represents a leap forward for our industry. Wi-Fi users worldwide will benefit from a single-technology solution to transfer content and share applications quickly and easily among devices, even when a Wi-Fi access point isn't available,' said Wi-Fi Alliance executive director Edgar Figueroa. 'The impact is that Wi-Fi will become even more pervasive and useful for consumers and across the enterprise.' Ad hoc wireless networking has always been more complex and cumbersome than it is worth, and it maxes out at 11 mbps. Wi-Fi Direct will connect at existing Wi-Fi speeds-- up to 250 mbps. Wi-Fi Direct devices will also be able to broadcast their availability and seek out other Wi-Fi Direct devices. Wi-Fi Direct overlaps into Bluetooth territory. Bluetooth is a virtually ubiquitous technology used for wireless connection of devices like headphones, mice, or the ever-popular Bluetooth earpiece sticking out of everyone's head. Bluetooth uses less power, but also has a much shorter range and slower transfer speeds. Wi-Fi Direct can enable the same device connectivity as Bluetooth, but at ranges and speeds equivalent to what users experience with existing Wi-Fi connections."

Comparing Performance and Power Use For Vista vs. Windows 7 WIth Clarksfield Chi 119

crazipper writes "Back when Intel launched its Core i5/i7 'Lynnfield' CPUs, Tom's Hardware ran some tests in Windows 7 versus Vista to gauge the benefits of the core parking and ideal core optimizations, said to cut power consumption in the new OS. It turned out that Win7 shifted the Nehalem-based CPUs in and out of Turbo Boost mode faster, resulting in higher power draw under load, while idle power was a slight bit lower. The mobile version of the architecture was claimed (at the time) to show a greater improvement in moving to Win7. Today there's a follow-up with the flagship Clarksfield processor that shows the same aggressive P-state promotion policies giving Win7 a significant performance advantage with Core i7 Mobile. However, power consumption is higher as well."

Acer Launching Dual Android/Windows 7 Netbook 105

Barence writes "Acer has unveiled an Aspire netbook that dual boots Google Android and Windows 7. 'User demand is not there for [other forms of] Linux [but] we never give up. We adjust,' said Jim Wong, Acer senior corporate vice president. 'We introduce Android with the Windows OS, and why Android? Because it has the best connectivity built into the OS.' Acer has also talked up Google's forthcoming Chrome OS. 'Chrome can be a viable alternative to Microsoft's OSes for web applications on different mobile devices,' he explained."

Decoding Adobe's Big Device Push 181

nerdyH writes "Adobe yesterday chummed the waters around Flash and AIR as cross-platform app dev environments for mobile devices. It promised runtimes for several popular mobile OSes, including WinMo, Symbian, Palm webOS, and Android, with future RIM/Blackberry support hinted as well. Moreover, it reiterated its commitment to the Open Screen Project, an Adobe-led industry group that, if you deconstruct its name and look at its membership roster, appears tactically focused on enabling hardware acceleration of Flash/AIR on devices, as part of a larger strategy of making the runtimes ubiquitous as UI development frameworks for essentially every computer-like device with a user interface."

Best Developer's Laptop? 672

s31523 writes "I love my current laptop, but unfortunately on my last trip the primary LCD went bonkers. It's an older Gateway (2 GB RAM Intel Pentium M 2.0 GHz, ATI M7). There are a handful of features I love about it: [1] Hot-swappable drive bay, with several components that can go in: CD/DVD R/W, extra battery, floppy drive, extra hard drive, memory card reader, etc. The extra battery option is especially appreciated — I can go 4-5 hours on battery power. [2] Docking station / port replicator: I like having my home setup with keyboard, network, and dual screens (a necessity). [3] It runs Linux. OK, I'm a wus, I actually have GRUB command three different OS's: Windows 98 (I have really old embedded software compilers that only run on 98, and yes I have tried every trick in the book to make them run on Linux), Windows XP Pro, and Ubuntu. I'm trying to find a replacement setup that offers the same flexibility and a little better performance. I am open to change as well. So, I ask Slashdot: What is your pick for best developer's laptop under $1,200, considering the features above?"

ARM and Dual-Atom Processors in New Portables 147

chrb writes to tell us that Dell's new Latitude Z has finally been delivered as promised, complete with ARM processor. Codenamed BlackTop, the device runs a modified version of Suse Linux, and is capable of near-instant bootup. Dell's research has apparently found that some early users spend 70% of their time in the Linux environment." Relatedly snydeq writes "Colombian computer maker Haleron has designed a netbook that combines Atom processors in an effort to provide the performance of a standard laptop at a price more affordable to Latin Americans. The Swordfish Net N102 includes two Atom N270 processors running at 1.6GHz. Haleron worked for six months to modify Intel's 945 chipset to run the two processors. The processors divide the workload, much like a dual-core processor does, the company said. The netbook, which begs the question, when does a netbook stop being a netbook, comes with Windows XP Home Edition. 'We found that it works best on the Windows XP operating system. Both Windows Vista and the new Windows 7 performed below Windows XP in the load sharing department,' the company said."

Making Safer Lithium-Ion Batteries 77

itwbennett writes "Exploding iPhones may be a thing of the past. Researchers at Taiwan's Industrial Technology Research Institute have developed a new polymer, STOBA (that's self-terminated oligomers with hyper-branched architecture to you and me), that is added to the cathode material inside a lithium-ion battery to keep them from overheating. 'Fires or explosions in these batteries are caused by short circuits,' said Wu Hung-chun, a researcher at ITRI, explaining that even minor mishandling such as dropping the handset could result in damage causing a short circuit. 'The technology is ready for lithium-ion batteries used in electronic devices, mobile phones, laptops,' said Wu. And ITRI has started testing STOBA on electric car batteries."

Early Details On Courier, Microsoft's Take On a Tablet 175

rbanffy points out an article on Gizmodo about Courier, a tablet (or more accurately, a booklet) in development at Microsoft. "The dual 7-inch (or so) screens are multitouch, and designed for writing, flicking and drawing with a stylus, in addition to fingers. They're connected by a hinge that holds a single iPhone-esque home button. Statuses, like wireless signal and battery life, are displayed along the rim of one of the screens. On the back cover is a camera, and it might charge through an inductive pad, like the Palm Touchstone charging dock for Pre." A concept video shows off the ability to use the two different screens for separate purposes, like browsing the web or a photo album on the left and using the right as a notepad or workspace.

Intel Core i7 For Laptops — First Benchmarks 196

Barence writes "PC Pro has benchmarked the first Intel Core i7 processors for laptops. The chips mark the debut of Intel's Turbo Boost technology, which ramps up the speed of the working cores if two or more cores are sitting unused. For the quad-core i7-820QM, this can take the stock speed of 1.73GHz up to a maximum of 3.06GHz. The 2D benchmarks show comparable performance to Core 2 Extreme chips running at 2.53GHz. Power consumption and processor temperature is dramatically lower, which should lead to significant improvements in laptop battery life."

Which Filesystem Do You Use On Portable Media For Linux Systems? 569

An anonymous reader writes "Most people use MS filesystems on Disk-On-Keys, and portable hard drives, as these are readable from most machines. But this way you lose the files' permission information, which many times is very inconvenient (you must agree that having Ubuntu asking you whether to execute or display every text file or image you open from a DOK is annoying). Using 'regular' Linux filesystems like ext keeps the permissions, but may require using the superuser when switching machines (as the UIDs are different). So do any of you have a creative solution for this problem?"

Asus Plans Dual-Display E-Reader 199

adeelarshad82 writes "Yet more confirmation has emerged that Asus plans its own e-book reader. An Asus representative in the UK appears to have confirmed this, with the additional details that there may be a value-priced as well as a premium version. The article guesses at the price point for the low-end model — around £100 ($192). Unlike current e-book readers, which take the form of a single flat screen, the Asus device has a hinged spine, like a printed book. This, in theory, enables its owner to read an e-book much like a normal book, using the touchscreen to 'turn' the pages from one screen to the next. Asus showed off a prototype of the device at the CeBIT trade show in March." Reader NeverBotedBush adds, "Asus's e-reader will likely have color touch screens, a speaker, a webcam, and a microphone, along with the capability to make inexpensive Skype calls." The color screen rules out using E Ink technology, so long battery life seems to be unlikely.

Why Is Linux Notebook Battery Life Still Poor? 907

Ganty writes "I recently purchased a Lenovo W500 notebook, and after 'downgrading' to XP and creating a dual partition, I found that I had a battery life of nearly three hours using the long-life battery, at this point I was a happy camper because it means that I can watch a DVD during a flight. I then tried various Linux distributions and found the battery life under FOS to be very disappointing, with an average of 45 minutes before a warning message. After settling on Ubuntu I then spent three days trying various hardware tweaks but I only managed to increase the battery life to one and a half hours. Unwanted services have been disabled, laptop mode has been enabled, the dual core CPU reduces speed when idle and the hard drive spins down when not needed. Obviously Apple with their X86 hardware and BSD based OS have got it right because the MacBooks last for hours, and a stock install of MS Windows XP gives me three hours of life. Why is battery life on notebooks so poor when using Linux? Some have suggested disabling various hardware items such as bluetooth and running the screen at half brightness but XP doesn't require me to do this and still gives a reasonable battery life."

Dell Considering ARM-Based Smartbooks 298

wonkavader sends us this quote from an article in PCWorld: "In an effort to expand its Linux offerings, Dell is researching new netbook-type devices and will soon offer netbook Linux OS upgrades, a company official said on Wednesday. The company is researching the possibility of offering new Linux-based mobile devices called smartbooks, said Todd Finch, senior product marketing manager for Linux clients, at the OpenSourceWorld conference in San Francisco. The company will also upgrade its Ubuntu Linux OS for netbooks to the latest version in the next few weeks ... Smartbooks with Arm chips have inherent advantages over x86 chips like Atom, such as lower power consumption and longer battery life, according to Finch. The chips are also becoming more powerful, as indicated by the growing number of applications on smartphones, he said. 'I think it's natural and reasonable for us to begin looking at them as they begin scaling their processors up.'"
