The last time we saw an EV pit itself against a BMW, it wasn't a good day for the German car. On this occasion, the beemer is the EV, and it's one that all the others will officially have to enjoy viewing from behind. The car in question is the Rimac e-M3, the fledgling EV-firm owner's personal custom ride, and it's just been officially acknowledged as the fastest accelerating electric vehicle (with some category caveats). The record-breaking run actually happened April 2011, but it seems the FIA isn't quite so fast when it comes to making things official. The Croatian driver covered the first eighth of a mile in 7.549 seconds, needing less than five more for the same distance again (1/4 mile in 11.808 seconds). This is where the official-dom ends, but the total mile was completed in 35.347, which is still pending the FIA nod. Happy as driver Mate Rimac is, he already thinks there's something faster. What might that be? His new pre-production Concept_One of course. Catch the car in action after the break.

We know you've got questions, and if you're brave enough to ask the world for answers, then here's the outlet to do so. This week's Ask Engadget inquiry is from Whee!, which we guess probably isn't their real name, who is looking for a way to ditch their mouse. If you're looking to ask one of your own, drop us a line at ask [at] engadget [dawt] com.

"I'm a web developer, and my typical day involves a lot of moving and clicking when testing stuff in the browser. I've been thinking about ditching my mouse, because when using it for long hours it gets very uncomfortable. As such, I'm eyeing up a Wacom tablet and using the pen input to mouse around -- but do you think it's a good idea? Thanks in advance!"

Our questioner wants to solve their wrist-pain woes, and it certainly seems like a reasonable enough idea to us. Plenty of tablets come with a mouse mode, so it's just down to the limits of your budget.

• If you're just dipping your toes into the water, you can pick up a Genius device for around $60.
• Wacom's Bamboo tablets occupy the mid-range, setting you back $80 for a 5.8-inch model, all the way up to $200 for the 8.5-incher.
• If you're serious about making the change, then Wacom's Intuos5 hardware is a top-range option, with the 6.2-inch version starting at $200, running all the way to $800 for the 18-inch unit, or even spending big on one of the company's Cintiq units.
• We've also been wondering if a touchscreen Ultrabook might be a better idea, letting your fingers do the walking to spare your aching forearms.

That said, perhaps the wider Engadget community has an even better tip, so if you've already made that leap, why not share your knowledge in the comments below?

Just in case you thought Nokia's Lumia 822 for Verizon was an illusion, the FCC has given us good (if not quite smoking gun) evidence that it's tangible. A filing at the agency shows a device that's only listed as the RM-845 on the surface, but has Verizon's CDMA and LTE bands, measurements very close to those of the GSM-based Lumia 820 and a microSD slot that you wouldn't find in a Lumia 920 variant -- short of a surprise new model, there's little beyond the 822 that would currently fit the bill. Those disappointed that it's not a higher-end Lumia might take some consolation in seeing both the expected NFC as well as quad-band HSPA 3G for world roaming. Between the FCC and earlier photos, fans are really just left waiting for Verizon to make this new piece of its Windows Phone revival official, whether it's on October 29th or some other date.

Alt-week peels back the covers on some of the more curious sci-tech stories from the last seven days.

Are you reading this? Seriously, are you? Sure, we know you think you are, but what if you're just a sub-feature of a complex computer program. A sprite, nothing more than the creation of software. The problem with this question is, how would you ever know? You wouldn't, right? Well, not so fast there. Turns out, maybe there is a way to unravel the matrix (if there is one). It'll come as no surprise, that this is one of the topics in this week's collection of alternative stories. Think that's all we got? Not even close. We'll explore the truth behind cloning dinosaurs, as well a rare performance by singing mice -- all before dinner. Or is it really dinner? This is alt-week.

Just precisely how the T-Mobile / MetroPCS merger will pan out still seems yet to be decided. What is clear, however, is that majority share-holder, Deutsche Telekom, hope to have the deal done and dusted between April and June next year. CFO for the German giant, Timotheus Hoettges, told Boersenzeitung that we'll have to wait until the second quarter of 2013 before one of the parties will have to start ordering new stationary and corporate polo shirts. In the meantime he was keen to point out that not all current financial arrangements should feel ause for concern, noting shareholders wouldn't have their remuneration policy affected by the merger, thanks to the spiffy financial year it's had.

The fact that ISPs are working with the RIAA in a bid to squash piracy is far from new. A leaked document claiming to be AT&T training materials, however, suggests that the operator is about to stop talking, and start doing. According to TorrentFreak notifications will be sent out to customers on November 28th about the change in policy, with those suspected of illicit downloads receiving an email alerting them of the possible copyright infringement. We'd previously heard of a six-stage notification system, and this, too, is mentioned here with repeat offenders facing access to "many of the most frequently visited websites" restricted. Even stranger, is the talk of having to complete an online tutorial about copyright to get the restrictions lifted. As AT&T is part of the MPAA and RIAA-backed Center for Copyright Information, it's likely that the other members (Verizon, Comcast, Time Warner Cable and Cablevision), will be prepping similar plans. We've asked AT&T for confirmation directly, but for now keep an eye on the mail.

Yes, we'll admit that we borrowed that pun in the title. MooresCloud founder Mark Pesce's Xzibit reference is still a very apt description of the Light, his company's Linux-based LED lamp. The Australian team's box-shaped illumination runs the open OS (including a LAMP web server stack) on an integrated mini PC with an accelerometer and WiFi. The relative power and networking provide obvious advantages for home automation that we've seen elsewhere, but it's the sheer flexibility of a generalized, web-oriented platform that makes the difference: the Light can change colors based on photos or movement, sync light pulses to music and exploit a myriad of other tricks that should result from a future, web-based app store. When and how the Light launches will depend on a Kickstarter campaign to raise $700,000 AUD ($717,621 US) starting on October 16th, although the $99 AUD ($101 US) cost is just low enough that we could see ourselves open-sourcing a little more of the living room. At least, as long as we don't have to recompile our lamp kernel before some evening reading.

Apple gave eco-friendly computer fans a brief jolt this July after it backed out of EPEAT certification, only to restore most devices just days later. While we can't say we're completely shocked at the follow-up, EPEAT has confirmed that at least one "ultra-thin" laptop from Apple has just cleared the verification process. The as yet unnamed system is more likely to be a Mac that had already earned the recycling-friendly rating in the past, such as the MacBook Air, rather than a sudden turnaround for the MacBook Pro with Retina Display. The look wasn't exclusively devoted to the Mac side, though -- EPEAT cleared Apple's computer as part of a wider test that also greenlit extra-thin portables from Lenovo, Samsung and Toshiba. We've reached out to get a more definitive list, but the approvals should ease the minds of those worried that ever-slimmer laptops are forcing us to give up our green efforts.

Technologies like NFC, RFID and QR codes are quickly becoming a normal part of everyday life, and now a group from Carnegie Mellon University has a fresh take on close-quarters data it calls acoustic barcodes. It involves physically etching a barcode-like pattern onto almost any surface, so it produces sound when something's dragged across it -- a fingernail, for example. A computer is then fed that sound through a microphone, recognizes the waveform and executes a command based on it. By altering the space between the grooves, it's possible to create endless unique identifiers that are associated with different actions.

It's easy to see how smartphones could take advantage of this -- not that we recommend dragging your new iPhone over ridged surfaces -- but unlike the technologies mentioned earlier, not all potential applications envisage a personal reading device. Dot barcodes around an area, install the sound processing hardware on site, and you've got yourself an interactive space primed for breaking freshly manicured nails. We're pretty impressed by the simplicity of the concept, and the team does a good job of presenting scenarios for implementing it, which you can see in the video below. And, if you'd like to learn a little more about the idea or delve into the full academic paper, the source links await you.

We're quite familiar with ruggedized camcorders here at Engadget, be they from GoPro or Contour. However, Sony recently entered the extreme video fray with its Action Cam, and we got the chance to do a little POV recording with one. The videos produced were on par with what we've seen from the Action Cam's competition -- a nice wide view and decent quality. While we've seen other such cams have trouble with color balance, the Sony's was accurate both indoors and out and it adjusted to transitions from dim to bright environments quickly. And, while the SteadyShot image stabilization tech didn't eliminate all the shakes in our videos, it did noticeably reduce them. That said, you don't have to take our word for it, head on past the break and see the results for yourselves.

AllThingsD and CNET are reporting that 30 percent of AMD's workforce could be laid off, though one of several unnamed sources notes the cuts could be as low as 10 percent. If these reports hold true, this would be the second round of layoffs for AMD within a year's time. The reductions will reportedly affect the firm's engineering and sales employees, and may be serious enough to cause a paring back of product lines. The silicon giant could potentially reveal its plans as early as next week, which would coincide with the announcement of its third quarter financial results. With the company expecting a ten percent revenue drop in Q3, it looks like the latest figures will continue the trend of less than ideal results.

A launch event invitation has already given us a glimpse of the ASUS PadFone 2, but Bloomberg TV India caught up with the firm's CEO Jerry Shen and snagged a video tour of the device before its October 16th reveal. The second iteration of the PadFone packs a 4.7-inch HD (presumably 720p) screen and 13-megapixel camera, which jives with specs on supposedly leaked packaging. Rather than having to fuss with a cover flap to slide the smartphone into its tablet shell, users will be able to dock the device straight into a lighter and thinner slate component. Other details are scarce, but we're sure to find out more when the curtain is ceremoniously pulled back next Tuesday. In the meantime, you can forge past the break to see footage of the hybrid starting at the 1:40 mark.

Update: The ever-prolific evleaks has just tweeted out a glamour shot of the PadFone 2 and its accompanying tablet dock.

Update 2: Evleaks has tweeted additional pictures which we've collected in the gallery below for your perusal.

Padfone 2 leaked press shots

We can't say we're exactly surprised Sprint would be bringing its 4G LTE waves to one of the biggest markets on the West Coast, but there's nothing like hearing it straight from the horse's carrier's mouth. Earlier today, Sprint announced its developing Long Term Evolution network will be hitting San Francisco (and some surrounding areas) in the "coming months." That's not it, however, as the Now Network also let it be known that it will be flipping the switch in more than 20 other new markets, including Fort Wayne, IN, Emporia, KS, Greenwood, MS, Joplin, MO as well as Napa and Petaluma in California. At this very moment, it's unclear what Sprint's definition of "in coming months" is, but at least folks living around these areas now have some reassurance that they, too, will be enjoying some faster speeds on one of those LTE-equipped devices. The full list of lucky markets can be found inside the presser below.
