plans to sell customer information to the retailer has been delayed.

Borders, which filed for bankruptcy in February, is going out of business. At an auction last week, Barnes & Noble agreed to pay $13.9 million for a large portion of Borders' intellectual property assets, which includes customer information.

A judge said he needs more time to consider Borders' privacy policy before the sale can take place.

Facebook

is still trending as even more changes are hitting the social network.

CEO Mark Zuckerberg announced at Facebook's F8 conference on Thursday that a new Timeline feature will replace the old user profile layout. Timeline will show a user's entire history on Facebook, with a heavy focus on pictures and video. Users can customize their own Timelines or click on any given year on another user's Timeline to see what they have done in the past.

Timeline is currently going through beta testing and should be available in a couple of weeks.
