Facebook introduces 'Relevance Score' for ads
In another effort to refine and improve ads that users see in their Facebook News Feeds, the company introduced a Relevance Score for ads this week.
The scores, which are based on a scale of 1 to 10, measures how well the ad will perform for its targeted audiences. The numbers are a reflection of the ratio of positive to negative interactions.The new measurement is not used for ads with guaranteed delivery — those bought through reach and frequency. "Relevance score has a smaller impact on cost and delivery in brand awareness campaigns, since those ads are optimized for reaching people, rather than driving a specific action like installs," Facebook explained in a blog post.

legacy contact - How to decide who inherits your Facebook account
Facebook introduced a new legacy contact feature in the U.S. on Thursday — allowing users to choose who can manage their accounts once they've died — and it's something we should all think about activating.While no one wants to think about his or her own death, this kind of option is going to become increasingly common as we share more of our lives online
As Facebook says, "When a person passes away, their account can become a memorial of their life, friendships and experiences." While you might initially cringe at such an option, remember: It could provide comfort to your friends and family.
Facebook bug would have allowed hackers to easily delete your photos
A blogger named Laxman Muthiyah discovered the issue. This was all able to happen by exploiting Facebook's Graph API, which is the HTTP-based software that allows the website to function. Graph API requires a token to mess with someone's data, but Muthiyah tricked Facebook, using his own token, into deleting other people's pictures.
Alert! 4GB iOS apps are coming soon
Apple doubled the size limit of iOS apps from 2GB to 4GB, the company told developers Thursday. So app makers "can include more media in their submission and provide a more complete, rich user experience upon installation," Apple said.The 2GB limit had been in place since the launch of the App Store in 2008
This move from apple is a huge deal for game devolopers. It will help them to overcome the size restriction of upgrade game versions.
Upping the limit may suffer little for iOS users with lower capacity devices. As display quality continues to improve and developers make bigger apps, 8GB and 16GB iPhones and iPads will feel more and more restrictive.
Threat Exchange - Social Media platform from facebook for sharing Cyber Security threats
Facebook launched a new platform called ThreatExchange for security, professionals to exchange information about cyberthreats with greater ease.
"Our goal is that organizations anywhere will be able to use ThreatExchange to share threat information more easily, learn from each other's discoveries, and make their own systems safer," Mark Hammell, Facebook's manager of threat infrastructure, wrote in a blog post announcing the project.
Advantage of this new platform is researchers and professionals can learn from each other, and help keep everyone's systems safer.The new platform builds on Facebook's ThreatData, a framework that stores cyberthreat information (such as bad URLs) for analysis by security pros.Currently, ThreatExchange is in beta, but for those interested in participating, there's a sign-up form over on its website.
Security threats aren't typically relegated to just one target, and the lack of communication between malware targets ends badly for everyone, according to ThreatExchange. So far, some pretty big-name Internet players have joined Facebook on ThreatExchange, including Bitly, Dropbox, Pinterest, Tumblr, Twitter and Yahoo. The platform expect to attract more partners as time goes on.
Facebook thinking about this new idea about a year ago because malware attack for thier websites. Any way Threat Exchange is a good news for social media companies to keep thier data safe.
