MIT prof and student discover algorithm for predicting trending Twitter topics

Predicting the future of Twitter's trending topics is, as of right now, an impossibility. But two folks at the Massachusetts Institute of Technology may have cracked the code with an algorithm they're saying predicts -- with 95 percent accuracy -- the topics that will trend in the next hour and a half. The prediction has even been calculated as high as four to five hours ahead of time with the same level of accuracy. Not too bad!

Of course, beyond impressing friends with the predictions, the algorithm has direct implications for the likes of Twitter itself -- being able to sell ads against trending topics could benefit the social media company enormously in its ongoing quest to monetize. At any rate, it's distinctly less dangerous sounding than the last idea we heard involving Twitter and predictions. The algorithm will be presented next week at MIT's Interdisciplinary Workshop on Information and Decision in Social Networks, should you wish to dig into the nitty gritty of the math behind the madness.

Google explains how its Android 4.2 malware scanner guards the side door

Side loading apps on Android implies a whole set of security holes, but the new malware scanner included in Android 4.2 could provide a much-needed plug. Talking to Computerworld, Android VP of Engineering Hiroshi Lockheimer revealed that Google's been analyzing APKs that crop up online, regardless of whether they're official market apps or not, in order to maintain a growing database of good and bad code. The scanner -- shown above -- then works in a similar way to the Bouncer on the front gate, comparing all the apps on your phone to that database. The new sentry helps Google build upon other Android 4.2 security features such as an improved app permission screen and a block against apps sending premium SMS messages in the background. On the other hand, some might say that collecting samples of existing malware will never be as powerful as truly understanding its DNA.

Microsoft explains the origins of Windows Phone 8's home and lock screens

We've delved into just what we think of Windows Phone 8's interface, but not what led Microsoft to the final layout. The company isn't content to let us wonder -- a pair of new company blog posts explain some (though not all) of what was involved in that birthing process. Ignore the marketing spin and you'll learn that the wider, more densely packed home screen was chosen as much for balance as to stuff in more home tiles, and that it caused a momentary crisis for the app list as a result. The Redmond team goes on to justify choices behind the lock screen, such as why notifications are as customizable as they are, why the music controls fade and why there's a failsafe for PIN attempts. Don't expect to come out of the explanations suddenly craving a Lumia 920; just expect to make more sense of the OS inside.

Skype 6.0 lands with Microsoft and Facebook account integration, Retina support

You're probably saying to yourself, "didn't Skype just get a Windows 8-friendly refresh?" Why yes, yes it did. But Skype 6.0 here isn't limited to Windows RT slates, instead it's designed for more traditional Windows systems and even has a similarly numbered OS X counter part. There's a number of notable changes here, including the ability to sign in directly with your Facebook or Microsoft account. (If you've got a Live Messenger, Hotmail or Outlook.com account, then you've got a Microsoft account.) The most visible changes, however, will be the "flattened" Don't-call-it-Metro-friendly UI on Windows and the addition of Retina display support on OS X. There's a few other minor changes, including some additional localizations, which you can read about at the source. And heck, since you're already there, might as well download Skype too.

LaCie intros Porsche Design drive for Macs with SSD and USB 3.0, helps the speed match the name

Porsche Design may not be directly involved in building German supercars, but there are certain expectations to be met, aren't there? LaCie is rolling out a new version of its Porsche Design hard driveskewed towards Mac owners that should offer more of the performance you'd associate with the automotive brand. The P'9223 Slim SSD is a third thinner than its ancestor but carries the option of a 120GB SSD that makes the most of the USB 3.0 port. If all runs well, nearly any Mac launched in 2012 can shuttle data along at a brisk 400MB per second. Demanding Mac fans will need to pay $150 for the flash-based edition to have the P'9223 feel truly Porsche-like; others only have to spend $100 if they're content with the Volkswagen pace of a 500GB spinning drive.

Nexus 4 appears early at Carphone Warehouse, October 30th release date

Whoa there! The next Nexus just got an early reveal over at UK retailer Car phone Warehouse. Delivery is currently pegged for October 30th and apparently it's got brand new Android 4.2 (or Android 4.1.2 -- the listing mixes in both). The pre order screen confirms plenty of details we've already heard, including that 4.7-inch 1,280 x 768 display, Snapdragon S4 processor and 8-megapixel camera. Unfortunately, at least according to the phone seller, there's only 8GB of storage and no micro SD card slot. Other curious parts include a "360-degree camera", whatever that is, and an on-screen render that's been previously been identified as a custom ROM. Diving into the supposed feature list, we're intrigued to see whether "gesture typing" will form a part of Google's new Android build -- the Car phone Warehouse compares it to Swype's finger-dragging input method.

Price-wise, it looks like you could get the handset for free on contracts over £31 per month, with both O2 and Vodafone named as prospective networks for the device in the UK -- but no news here on whether the 4G-capable EE will offer an LTE iteration. Excited? Good, because we're going to hear plenty more on this next week.

Update: And the page has been pulled. Hopefully, to iron out some of those suspect features...

Jelly Bean rolling out to Samsung Galaxy S III on Sprint beginning today

Apple Q4 2012 earnings: $36 billion in revenue, $8.2 billion net profit

Just a day after introducing the iPad mini, a revised iMac, a 4th-generation iPad and a retooled Mac mini, the company is outing its Q4 2012 earnings -- and it looks as if it has narrowly fell short of Wall Street estimates. Revenue was pegged at $36 billion (compared to estimates of $35.08 billion), with net profit at $8.2 billion. For the sake of comparison, the outfit's fourth quarter of 2011 saw $28.27 billion in revenue alongside $6.62 billion net profit -- at the time, those comically large numbers were actually not up to Wall Street's comical expectations. If you're looking for a quarter-over-quarter comparison, the company's Q3 2012 report showed $35 billion in total revenue, with $8.8 billion in net profits.

The company is guiding for $52 billion in revenues for Q1 2013, while announcing that it sold 26.9 million iPhones (up from 17.01 million a year ago), 14 million iPads (up from 11.12 million) and 5 million Macs (up from 4.89 million) in this quarter. As for the waning iPod business? Predictably, it sold just 5.3 million of those, representing a 19 percent drop from the year-ago quarter. Naturally, the company is expecting its next earnings report to be the one that blows everyone away, with holiday sales -- combined with a slew of new kit -- to propel things leading into 2013. Apple also announced that shareholders that hold stock as of November 12th will pick up a $2.65 / share dividend.

As for other specifics, we're told that gross margin was 40.0 percent compared to 40.3 percent in the year-ago quarter, while international sales accounted for 60 percent of the quarter's revenue. Peter Oppenheimer, Apple's CFO, proudly boasted: "We're pleased to have generated over $41 billion in net income and over $50 billion in operating cash flow in fiscal 2012. Looking ahead to the first fiscal quarter of 2013, we expect revenue of about $52 billion and diluted earnings per share of about $11.75." As for the outfit's current stash of on-hand cash? $121.3 billion. Yeah. The financial results call will get going at 5PM ET, and we'll be liveblogging it right here!

Apple adds Rubles and other currencies to App Store, bumps minimum price to €0.89 in Europe

After announcing slightly under par financials, Apple has added more ways it can be paid for apps, though it also bumped the minimum freight to get one across Europe. The new lowest price users in France, Germany, Italy and other nations "over there" can pay for an app is now €0.89, a euro-dime bump from before -- apparently due to the weak euro and local tax hikes. On the other hand, Cupertino also added more currencies accepted at its store: South African Rand, Turkish Lira, Russian Rubles, Indian Rupees, Isreali New Shekel's, Saudi Arabian Riyal, Indonesian Rupish and UAE Dirham can all now be used to pay. Apple has tinkered with its prices before in varying amounts overseas depending on the nation, so you may want to check your own country's App Store for the news -- bad or good.

Clearwire sees wholesale revenues dip, LTE delays as it posts a $41.3 million net loss in Q3

Clearwire's figures show that the network it isn't cool to love will be making placating faces at its bank manager for yet another quarter. It pulled in revenues of $313.9 million for the three month period, but with business costs (and depreciation) clocking in at $646.7 million, the company posted an operating loss of $332 million and a net loss of $41.3 million. If that wasn't bad enough, it's also hacked back a target to add TD-LTE to 5,000 sites before mid-2013 to just 2,000. A similar problem has occurred over at newly-minted majority owner Sprint, which has found itself a quarter behind its own LTE timetable thanks to parts shortages -- so let's hope the folks over at Softbank can help both companies improve their estimating skills.
