Network specialist Nortel announced on Monday that it has been selected as the high bidder in the auction of nearly all of the optical networking and carrier Ethernet assets of Nortel's Metro Ethernet Networks (MEN) business. Under terms of the deal, Ciena will pay $530 million in cash and issue $239 million in aggregate principal amount of 6 percent Senior Convertible notes due in 2017. All tallied, the deal is worth $769 million.

"These optical and carrier Ethernet assets bring exceptional technologies, talent and scale that will accelerate Ciena’s current strategy to deliver innovative network solutions to customers worldwide," said Gary Smith, Ciena’s CEO and president. "With this combination, we are bringing together complementary technologies in switching and transport to create an innovative powerhouse with the scale to challenge the industry status quo and offer customers a practical path for transitioning to automated, optical Ethernet-based networking."

Ciena has high hopes for its latest acquisition, and not without merit. In 2008, Nortel generated about $1.36 billion in revenue, and $556 million (unaudited) in the first half of 2009.

At least 2,000 Nortel employees will be offered employment to become part of Ciena's global team of network specialists, the company said.

Maybe Miley Cyrus was on to something, or perhaps she started a trend. But whatever the reason, Twitter's rapid rise appears to have to turned into a downward tumble, according to data provided to eMarketer by Nielsen.

We're not talking about just a few Twitter users leaving the service. According to Nielsen, traffic to Twitter slid 27.8 percent between September and October, dropping from 26.2 million unique visitors to 18.9 million. Nielsen's numbers were perhaps the most dramatic, but other research firms also noted a decline. According to comScore, unique visitors were down 8.1 percent in October, while Compete noted a more modest 2.1 percent drop.

No matter whose numbers you trust, the drop in traffic is concerning for one of the hottest services on the web. But are they telling the whole story?

"While it's valuable to look at Twitter's web traffic, the true picture won't emerge until all the third-party traffic from mobile phones and API clients is accounted for," wrote senior analyst Debra Aho Williamson on the eMarketer blog.

Is your ultraportable overheating while surfing the web? As odd as it sounds, the culprit could be Firefox rather than a hardware issue. No, really, check out what one of Mozilla's support pages has to say on the matter.

"At times, Firefox may require significant CPU resources in order to download, process, and display web content," Mozilla states in a document titled "Firefox consumes a lot of CPU resources."

As CNet notes, this is a real problem that users are reporting, such as this Dell Mini9 owner. So what's the solution? Short of switching to a different browser, Mozilla recommends downloading and installing the latest version of the Flash plugin, which might help with Flash heavy sites like YouTube, and installing Flashblock, which allows end-users to selectively enable and disable Flash content.

Depending on when and where the high CPU usage kicks in, Mozilla also recommends updating the Adobe Reader plugin, configuring Firefox to open PDF documents outside of Firefox, and installing NoScript.

Have you noticed any unusual CPU activitiy or overheating woes while running Firefox? Hit the jump and let us know. 

We know exactly how popular Twitter has grown, but never did we consider that anyone could be arrested for not using the microblogging service. Apparently that's a real possibility, as teenager singer Justin Bieber and his entourage found out.

Bieber was supposed to appear at the Roosevelt Field mall on Friday, but decided to keep his distance because the crowd was getting a bit too rowdy. When the police showed up, they asked James A. Roppo, a record label exec, to help clear out the crowd by sending a Twitter message, and then arrested him after claiming he didn't cooperate, Newsday reports.

"We asked for his help in getting the crowd to go away by sending out a Twitter message,"  said Kevin Smith, Nassau County Police Det. Lt. "By not cooperating with us we feel he put lives in danger and the public at risk."

In a radio interview, Bieber said the scene was "so crazy" that he couldn't make his way into the building, adding that the authorities had threatened to put in him handcuffs and haul him off to jail.

Roppo could face charges that include criminal nuisance, endangering the welfare of a minor, and obstructing government administration, Smith said.

In a few more days, Black Friday will be here, and if you plan on braving the crowds, that means getting up early (or staying up late) and making a mad dash for the electronics section among a frenzy of shoppers with no qualms about pushing, shoving, and trampling anyone who gets in their way. But should your reach your destination unscathed, you may find that the deals are nothing to get excited over considering stores have already had to mark prices down in the current economic climate, or that quantities are so low that if you're not near the front of the line donning a pair of running shoes, you're going to miss out.

CNNMoney.com reveals that in some cases, stores may stock as little as 3 units of those enticing low-priced electronics advertised in your local flier. Sale items could also be "derivatives" of the real deal, such as a large screen HDTV with lower image quality or a less desirable image contrast.

"It's a sleazy practice," said Craig Johnson, retailing expert and president of retail consulting group Customer Growth Partners. "I am old school. If a retailer is advertising a juicy deal and they are not prepared to have in sufficient quantity, don't advertise it. Or give consumers a raincheck."

Engineering eggheads from the University of Cambridge have developed a system called ProFORMA (Probabilistic Feature-based On-line Rapid Model Acquisition), which is capable of turning any standard webcam into a pretty powerful 3D scanning tool. A video demonstration shows how it's done, which you can view here.

What's pretty amazing is that the 3D models are constructed in real-time as end-users slowly rotate objects with their hand in front of the webcam. The engineering team says the system works by "calculating the Delaunay tetrahedralisation of a point cloud obtained from online structure from motion estimation, which is then carved using a recursive and probabilistic algorithm to rapidly obtain the surface mesh."

Put more simply, the system generates and displays partial models of an object on the fly, which then allows the user to plan how to manipulate the object to generate additional views. The finished product is a 3D representation of the object that can then be tracked with rapid movements.

It didn't take long for hackers to take advantage of a potentially dangerous exploit affecting jailbroken iPhones. The vulnerability first gained notoriety earlier this month when a hacker from the Netherlands took control of modified iPhones and sent the owners an SMS requesting a fee for instructions on how to protect thier device. He later backed down and posted the fix for free, but by then, the cat was out of the bag.

Fast forward a few weeks and we now have the first malicious worm making the rounds on jailbroken iPhones and iPod touch devices. According to reports, the worm uses command--and-control like a traditional PC botnet. it configures two startup scripts, one of which is used to execute the malicious worm during boot, and the other to make a connection to a Lithuanian server in order to upload stolen data and hand over control to the bot master.

The worm works by changing the root password from the default of "alpnie" that Apple put in place in the factory firmware. It attacks IP ranges from a wider range of ISPs, including UPC, Optus, and T-Mobile.

The recommended fix is to restore jailbroken iPhones to the current Apple-supplied firmware.

Remember when Juliet told Romeo that a rose by any other name would smell as sweet? We suppose the opposite must also be true, and America Online, whether abbreviated AOL or Aol, is still, after all, America Online.

The ISP on Sunday previewed its new brand identity, which it describes as a simple, confident logotype. The full identity won't be fully unveiled until December 10, when AOL common stock begins trading on the NYSE.

"Our new identity is uniquely dynamic," said Tim Armstrong, CEO of Aol. "Our business is focused on creating world-class experiences for consumers and AOL is centered on creative and talented people -- employees, partners, and advertisers. We have a clear strategy that we are passionate about and we plan on standing behind the AOL brand we take the company into the next decade."

Judging by the all-caps used throughout the press release, the new Aol branding looks to apply only to the company's "ever changing" logos, which were developed by branding outfit Wolff Olins.

We've been seeing signs of a market shift for some time now, and by the second quarter of 2010, global DDR3 shipments will finally surpass DDR2 for the first time, says market research firm iSuppli.

According to iSuppli, DDR3 is on pace to claim 50.9 percent of the market in Q2 2010, barely edging out DDR2. But what's most impressive is that DDR3's market share sat at only 14.2 percent in Q2 2009, and just 1 percent in Q2 2008.

"DDR3 is 50 percent faster than today's dominant DRAM technology, DDR2, while using about 30 percent less power," said Mike Howard, senior DRAM analyst for iSuppli. "For PC users across the board, this means faster performance. For notebook users, it can result in longer battery life."

Claiming a little over half of the market will be just the beginning, and iSuppli forecasts DDR3 will account for 71 percent of all DRAM by the end of next year.

This shouldn't come as a surprise to anyone who has been paying attention. Both Intel and AMD fully embrace the DDR3 standard, and while DDR2 used to enjoy a pricing advantage, that gap recently closed all but completely.

Living up to a promise made several weeks ago, the Roku Channel Store is now open. Unfortunately, rumors that the open platform for delivering content to Roku boxes would include support for Hulu turned to out to be false, at least so far. According to an article in Playboy magazine, "Hulu support is coming," but the video site wasn't among the first ten channels released, which includes Pandora, Facebook Photos, Revision3, Mediafly, TWiT, blip.tv, Flickr, FrameChannel, Motionbox, and MobileTribe.

"The Roku Channel Store turns the Roku player into the world's first open platform designed specifically for the TV," Anthony Wood, founder and CEO of Roku, said in a statement. "Now content producers and distributors -- from single person shops to billion dollar corporations -- can deliver their content directly to consumers without having to go exclusively through cable operators, satellite networks, or TV affiliates."

Roku said a free SDK is available upon request, which would allow developers to add to the Store's selection. As for the Channel Store itself, it's also free and is being distributed through automatic upgrades within the next couple of weeks. No Roku owners will be left out in the cold, as the Channel Store works on all Roku devices, the company said.

Internet Explorer users who have yet to upgrade to IE8 should take note. According to security firm Symantec, there's a pretty nasty Zero Day exploit that affects both IE6 and IE7.

"The exploit currently exhibits signs of poor reliability, but we expect that a fully-functional reliable exploit will be available in the near future," Symantec explained in a blog post. "When this happens, attackers will have the abilty to insert the exploit in websites infecting potential visitors."

Symantec said the attack requires JavaScript and recommends that users disable it. The security firm also suggested potentially affected users limit web surfing to only trusted sites until Microsoft releases a fix.

Who would've guessed that 18 of the top 20 most energy efficient supercomputers on the planet are built with IBM hardware? Let's be honest, who wouldn't have guessed it? This isn't the first time IBM has dominated the Green500 list, which includes a range of energy efficient supercomputers all around the globe, but it's hard not to be impressed that the company holds 69 of the top 100 positions on the list.

"Supercomputers can no longer focus only on raw performance. The era of simply adding more processors is coming to a close," said David Turek, vice president, deep computing, IBM. "Clients need to be able to run supercomputers anywhere, not only places that have cheap power. As the Green500 proves, IBM has focused on this issue for some time and is well positioned to usher in performance breakthroughs along with efficiency gains."

IBM also claims the most energy efficient system in the world with a supercomputer built at the Julich supercoming center in Germany. The machine is capable of producing more than 732 Mflops per watt of energy.

Oracle will have to wait a little bit longer before deciding on its next step in its planned $7.4 billion takeover of Sun. That's because European Union regulators on Friday said they have extended the deadline of its review until January 27 in response to Oracle asking for more time "in order to have the opportunity to further develop its arguments in response to the Commission's concerns."

The new deadline gives Oracle six additional days to plead its case, which consists of convincing the EU that the purchase of open-source database software MySQL isn't a conflict of interest and won't hamstring competition.

While the U.S. has already approved the multi-billion dollar deal, the EU contends that should Oracle acquire Sun, it would purposely kill off the free and open-source MySQL so as not to cannibalize its own paid server database software. But Oracle has accused the EU of not understanding the database market, particularly how it applies on the open-source level.

Should the EU ultimately rule against the deal, Oracle said it would fight the decision in court.

Oracle, in collaboration with SpringSource, has proposed a new Eclipse project called "Enterprise Modules," or "Project Gemini" if going by the platform's codename. The project is intended to provide a home for subprojects integrating existing Java enterprise technologies into mobile-based platforms, according to the proposal.

"The primary goal of the Gemini project is to provide access to standard enterprise technology implementations within a modular framework," the proposal states. "The OSGi [Open Services Gateway Initiative] Alliance has developed specifications for the application and usage of many of the enterprise technologies within OSGi. These specifications describe how vendors should implement and interoperate with existing services, and how the OSGi modularity, life cycle, and service models should be applied with respect to those technologies. Gemini will provide implementations of many of these specifications."

The Project Gemini proposal went on to claim that OSGi has been gaining in popularity among enterprise developers, and that the natural evolution is to now start creating standards for integrating popular enterprise technologies in module-based systems before serving up implementations for the general public.

Get ready for a blue Christmas if the only thing you asked for this holiday season was a Nook e-book reader. The device's popularity apparently caught Barnes and Noble off guard, who has sold out of the its initial supply and said preorders have exceeded expectations.

And if you listed Sony's Digital Edition Reader as your backup gift request, then it's a double dose of 'bah, humbug' coming your way. It too is in short supply, and Sony said it could not guarantee it would have enough to fulfill demand in time for Christmas.

The situation isn't dissimilar from what Amazon went through last year with its Kindle e-book reader, although the current king of the hill has managed to get its distribution channel squared away since then. So why are Sony and Barnes and Noble struggling?

"Even without specific problems in the supply chain, the manufacturing process takes time for new products -- it could be 3 months from the time they place the orders with their factories until they actually ship," Sarah Epss, an analyst at Forrester Research, said in an email. "Sony and B&N wanted to show the market they could compete with Amazon for the holiday season. Consumers responded enthusiastically, but unfortunately, these companies are struggling to deliver on their promise. Now they have to face disappointed consumers with empty packages under the tree."

According to Epps, both companies jumped the gun on their products announcements because neither was truly ready for the holiday shopping season.

Other items you're not likely to find in your stocking this year: HD 5970 videocard, handheld tablet.

Better late than never, and while it took a long time, iPhone and iPod touch users can now download Trillian, the multiprotocol IM client, through Apple's App Store.

The $4.99 app comes with many of the same features as its desktop counterpart, including grouped and sorted contacts. Tabbed chat windows also find their way onto the iPhone and iPod touch version, and so does the ability to copy and paste, which is more a credit to Apple than Cerulean Studios, the company responsible for Trillian.

Users can also synchronize content across multiple IM clients, so that changes made on the iPhone version will appear in real-time on the Windows client.

In a nod towards cloud computing, Cerulean Studios says that all chats are stored on the company's server, which means they won't be lost if you suffer a dropped connection. The app can also be set up to send IM alerts when Trillian is shut down.

AMD's newest HD 5970 is the fastest videocard on the planet, and as it turns out, it's also the hardest to find. And not just in the U.S. either, the card has been equally elusive in the EU.

According to news and rumor site Fudzilla, several AMD launch partners confirmed there would be limited availability of the card, and that's been the case so far. Newegg showed some stock in the wee morning hours on November 18th, but by the time noon (PST) rolled around, stock was gone. The $625 price tag doesn't appear to be slowing demand.

Fudzilla says it's been told to expect to see stock of the XFX Radeon HD 5970 and 5970 Black Edition sometime today, but it's unclear if that will include the U.S. market, or be limited to Europe.

Seen the HD 5970 in stock somewhere? Hit the jump and post a link. 

Whoever is the first to market with a next-gen handheld tablet will have accomplished what's becoming a tremendous feat: shipping the freaking thing. Michael Arrington insists that his CrunchPad hasn't entered the realm of vaporware, and Apple still continues to deny the existence of its own tablet, which the most recent rumor says will ship sometime in the second half of 2010.

And then there's the Archos 9 PC Tablet, which went up for order on October 22nd, but is still a few weeks away from shipping, SlashGear reports. If you plan on picking one up at retail, expect to wait even longer. According to Archos, the 8.9-inch Windows 7 UMPC won't arrive in stores until sometime in the first quarter of 2010.

Archos didn't say what's causing the delay, and it will be interesting to see how the pushed-back launch affects sales. By the time the tablet ships, Intel will be churning out next-gen Atom chips, making the Archos' 1.1GHz Atom Z515 even more unappealing.

Up to 1 million Xbox modders were pretty pissed to find that they had been banned from Xbox Live following the release of Call of Duty: Modern Warfare 2, the biggest launch in entertainment history. The mass ban was intended to prevent pirated copies of the highly anticipated game from spreading, a notion Microsoft will now have to defend in a class action lawsuit filed against the company.

"Although modification of Xbox consoles is arguably against he terms of use for Xbox/Xbox Live, Microsoft 'conveniently' timed the Xbox console ban to coincide with the release of the new Call of Duty: Modern Warfar 2 game and less than two months after the release of the very popular Halo 3: ODST game," says AbingtonIP, the Texas-based law firm who filed th suit.

According to the lawsuit, the timing of Microsoft's widespread ban may have resulted in more Xbox Live subscription sales than if the bans had taken place before the release of Halo 3: ODST and CoDMW2. The lawsuit also claims that some of the bans locked out users who had modded their consoles for reasons other piracy.

YouTube's reign as the No. 1 online video site doesn't appear to be in jeopardy, but among the also-rans, Facebook now ranks as the third most popular portal for viewing video on the Internet, according to Nielsen's VideoCensus report.

YouTube leads the way with 6.6 billion streams and just shy of 106 million unique visitors in October, leaving the real battle to be fought for second place. As it stands, the No. 2 spot belongs to Hulu, which served up 632.6 million streams and recorded 13.4 million unique visitors. Facebook trailed not far behind with 217.7 million streams, but had more unique visitors than Hulu with 31.6 million hits.

Not to underestimate the significance, Nielsen noted that the amount of time Web users spend hanging out at social networking sites watching videos increased 98 percent year over year. And viewing of video streams in general jumped by 26 percent, Nielseon said.
