How To: Snapchat Increases Its Security Push, Adds Image Captcha Feature

Snapchat has had more than its fair share of security failures and mishaps. The photo-sharing company is looking to better address some of these security gaps by adding new features, and today its most recent addition is live: the Captcha.

How To: Calculate compound interest in math
