Tesla to owners: Plug it in
EV maker Tesla has come under fire for allegations that its vehicles can be "bricked" when their batteries are completely discharged. Such instances require that the cells be replaced to the tune of $40,000, which doesn't sit well with folks who already forked over six figures to buy a Roadster in the first place. Tesla doesn't deny the charge (pardon the pun), but it does offer a common sense suggestion to avoid the problem: simply plug the car in. Tesla implies this danger is only likely for early adopters, and says it's also made strides to idiot-proof later vehicles with advanced warning systems -- Tesla 2.0 Roadsters can phone home to Tesla headquarters with a low juice alert, for example. Tesla documents safe battery charging practices in the owner's documentation, though, so here's an idea: if you're going to spend $109,000 on an electric sports car, maybe it's a good idea to RTFM (read the freaking manual).
T-Mobile keen to help iPhone users, plans to offer new procedures for unlocked phones
The iPhone might not officially be on the magenta network, but T-Mobile isn't about to turn its back on a million paying customers, either. According to a document obtained by TmoNews, the network plans to offer new "common procedures, information about feature and specifications and other basic device questions" to iPhone users starting Monday. T-Mobile has long had an open-door policy for customers with unlocked iPhones, since it doesn't have its own to sell -- though T-Mo CTO Neville Ray is hoping really hard that will change. Someday.
Google suggests TCP tweaks to make web pages load faster
Google has already proven it can load web pages as fast as lightning and flying potatoes, but its "Make the Web Faster" team has grander designs. The speed junkies want to quicken the internet by reworking Transmission Control Protocol (TCP), a key communications method that helps keep the internet working. Google says that it can reduce latency and speed things up by increasing the amount of data that initiates a TCP connection, reducing the initial timeout from three to one seconds, consolidating packets using its new TCP Fast Open protocol and adopting a better algorithm for managing network congestion. These changes are backwards-compatible and open source, but sadly don't include any way to speed up internet standards ratification and deployment, so ironically this might take a while.
Chevy Volt safe from fire hazard after all, says government
The Chevy Volt isn't prone to catching fire after all, says the National Highway Traffic Safety Administration. The all-electric car came under scrutiny last year after one caught fire following a side-impact crash test. GM offered a buyback program for Volt owners concerned their cars might suddenly immolate, then the company made "enhancements" to the Volt's battery coolant system. That set things right, as far as the NHTSA is concerned: it says "no discernable defect trend exists" in the Volt, and that GM's revisions "reduce the potential for battery intrusion resulting from side impacts." Chevy dropped the Volt's price by $1,000 for 2012, too. So what do you think? Is a $39,000 starting price and less of a chance of burning to death enough to make you go electric?
Razer punts Tiamat 7.1 surround sound headset release from Christmas to January
Razer just put a piece of coal in gamers' Christmas stockings with news that its hotly-anticipated Tiamat 7.1 surround sound headset has been delayed. Originally expected in Q4, its new release date is sometime in January. To recap, $180 will get you an unusual five drivers in each ear, including three dedicated left and right ones, along with a subwoofer and "center" channel on each side. There's the obligatory mic, along with an inline control that lets you adjust volume levels for each channel. So, will the extra drivers make much of a difference during your next Modern Warfare 3 firefight? Let us know. [Thanks, Zach]
Coming soon: pick airline seatmates via social networks
KLM Royal Dutch Airlines plans to launch a service in 2012 that will enable you to pick who you sit next to on an airplane by visiting their Facebook or LinkedIn pages. "Meet & Seat" will be an opt-in service (similar to that already toyed with by Malaysia Airlines), so you can still fly anonymously -- as anonymous as air travel gets these days, anyway. It could be great for making friends or developing business contacts on your next international flight, or it could make for some really awkward conversation too. "So, your Facebook profile says you like Justin Bieber?"
Microsoft adds open standard support to Messenger, third-party clients now welcome
Windows Live Messenger may not be as popular as it used to be, but it's still accessed by 300 million users, and Microsoft is now hoping to grow that by making it a little more open. The service now supports XMPP and OAuth 2.0, paving the way for other chat software and services to connect more easily (some already do, but by using unofficial methods). XMPP is a messaging protocol (previously known as Jabber and used by Google Talk) and OAuth 2.0 is an open standard for authorization that both Google and Microsoft have stepped out with early support for. Maybe by opening Messenger up a bit, Microsoft is trying to avoid what happened with ICQ.
Cheap electronic skin edges us closer to cyberpunk future
Researchers working for the Department of Energy's Berkeley Lab have figured out how to create relatively inexpensive "electronic skin" comprising carbon nanotubes enriched with semiconductors. Their process involves an enriched single walled carbon nanotube (SWNT) solution embedded in a honeycomb pattern of hexagonal holes to make it more flexible and stretchable - it's so limber, they wrapped it around a baseball, as you can see in the photo above. Combined with inkjet printing of electrical contacts, the technology paves the way for making flexible, wearable computers and a host of other cool things that William Gibson and other cyberpunk authors thought of back in the 1980s: smart bandages, flexible solar cells and electronic skin that can sense touch. Bring on the Zeiss eye implants and neural interface jacks!
Samsung 'Optical Sensor in Pixel' LCDs rolling out, ready for Surface 2.0
With Samsung's Microsoft Surface product, the SUR40, already available for pre-order, the company says its 1080p 40-inch "Optical Sensor in Pixel" LCD panels have gone into mass production. Those optical sensors help to more accurately interpret multi-touch input without interrupting display signals, offering a more fluid, interactive experience. Tempered glass overlaying the display supports 176 pounds of load and up to 50 touch points at once, which should be more than enough for a Pacific Giant Octopus or any jerk that leans on your $8K table. While the SUR40 is certainly a showcase device for these panels, it isn't the only practical application -- Samsung says it's thin enough and light enough to wall-mount, and hopes to see it used by stock brokers, financial analysts and schools.
Speedier Archos 101 G9 Turbo tablet hits the autobahn
Archos has tweaked its 101 G9 tablet with a new "Turbo" version for European users. The Turbo gets a 1.2GHz dual core processor, up from 1.0GHz, and increases storage capacity from 8GB to 16GB. Otherwise it looks the same: Android 3.2 Honeycomb, 10.1-inch display, and 802.11n WiFi support for faster porn downloads (it supports H.264 video, too). All this will set you back £299.99 or €349.99, though there's no sign of it in the US store at present. Leave it to the continent that gave us the Koenigsegg Agera and the Bugatti Veyron to get a turbocharged Android tablet, too. [Thanks, Chris]
Apple II drum sequencer surfaces for chiptune composers
No, this isn't a recycled news item from the 1980s -- it's 2011, and MJ Mahon and 8 Bit Weapon have just announced the release of the Apple II DMS Drummer, a wavetable-based drum sequencer for Apple II-era machines. The monophonic synth reproduces eight drum sounds like bass, snare, rim shot, hand clap, tom, hat open, hat closed and "lazer," along with a sequencer that lets you plug in up to 16 drum patterns across 256 slots. Seems like just the thing for chiptune composers hankering for a way to make authentic eight-bit drum tracks using vintage Apple hardware. System requirements call for an Apple IIe, IIc, IIc+ or IIgs with 80-column capability and a 5.25-inch floppy drive -- you know, pretty modern stuff. A limited demo version is available, but if that doesn't satisfy, you can either buy it on a floppy for $14.95 or download a .dsk disk image for $9.95. Oh, and neither require a time-traveling DeLorean to go back to 1985. [Thanks, Seth]
