Researchers Dhiru Kholia and Przemyslaw Wegrzyn have discovered a method to reverse-engineer Dropbox, which may open the door for open-source clients, but also gives attackers a way to intercept encrypted content and bypass the file sharing service’s two-factor authentication. The discovery has broader implications for the Internet, as the same methods could be used against any proprietary app built using the Python language. A Dropbox spokesperson said that while they “appreciate the contributions of these researchers,” the discovery “does not present a vulnerability in the Dropbox client.” Dropbox argues that the exploit will not work unless the user’s computer is already compromised. follow link
Option-click to Hide Apps Quickly
This trick has been available in the Mac OS for years, but many people still don't know it. If you have too many windows cluttering up your screen, you can hide specific ones easily as you work. When you're in any application, hold down the Option key and click on another app's window, on the Dock, or in the Finder to switch to that other app and simultaneously hide all the windows in the previously current app.
