The S-1 noted “popular Pages on Facebook include Lady Gaga, Disney, and Manchester United, each of which has move than 20 million Likes.” Many inside the company think the Hates could easily top that.

Software defined radio from a USB TV capture card
So far, two USB sticks have been tested and the unit with the largest frequency range (64 – 1700 MHz) is available direct from China for $20.
via Software defined radio from a USB TV capture card – Hack a Day.
These cards demodulate the frequency and send all the data to the computer and is decoded via software. If you have one of these capture cards lying around, you can grab the software and load it up on your *nix box. Right now, the software only writes directly to a file, and may drop a few samples if writing to a hard disk instead of ram. Small problems, but we’re sure this project will pick up steam in the very near future.
rtl-sdr – OsmoSDR
rtl-sdr is a commandline tool that can initialize the RTL2832, tune to a given frequency, and record the I/Q-samples to a file.
The code can be checked out with:
git clone git://git.osmocom.org/rtl-sdr.git

“Girls Around Me” Creeper App Just Might Get People To Pay Attention To Privacy Settings
For example: all these options in Foursquare default to on, which is really fine, since after all the service is about sharing your location. And linking it to your Facebook or Twitter account is a natural step for many. But at the same time it’s easy to fail to understand that one is providing a sort of path that strangers can follow from a face on the street to a name, other photos, current location, and a number of other things.
Foursquare
Foursquare, stylized as foursquare, is a location-based social networking website for mobile devices, such as smartphones. Users “check-in” at venues using a mobile website, text messaging or a device-specific application by selecting from a list of venues the application locates nearby.[3] Location is based on GPS hardware in the mobile device or network location provided by the application. Each check-in awards the user points and sometimes “badges”.
via Foursquare – Wikipedia, the free encyclopedia.
The service was created in 2009 by Dennis Crowley and Naveen Selvadurai. Crowley had previously founded the similar project Dodgeball as his graduate thesis project in the Interactive Telecommunications Program (ITP) at New York University. Google bought Dodgeball in 2005 and shut it down in 2009, replacing it with Google Latitude. Dodgeball user interactions were based on SMS technology, rather than an application.[4]
Tweet seats suit claims the process has been patented

Groupon reveals lower revenue, admits internal controls ‘weakness’
In its SEC filing, Groupon said it sets aside a refund reserve by applying a financial model based on refund patterns from previous deals. The problem with this approach was that refund behavior started changing in late 2011 as the company introduced higher-priced deals, which required commensurately higher refund payouts when customers requested returns. Groupon was still modeling the size of its allowance on lower-priced deals.

RIM’s Q4: Weak results, outlook and brutally honest CEO commentary
RIM gave the bears more ammunition to punish the stock. It’s trading below tangible book value and there’s no conceivable reason to expect that to change anytime soon. If anything, fears about RIM’s survival are becoming much more real.
I don’t mean to sound too harsh, but it’s obvious that a timely launch of BlackBerry 10 is RIM’s last chance. It’s a pretty GOOD chance, but if they screw it up we’re talking about break up value, take-out pricing and other less-than-ideal scenarios for investors.
