If you own a Synology NAS device and haven’t updated recently, you should. Attackers are taking advantage of an older vulnerability (patched in February 2014) to mine the Dogecoin virtual currency (an offshoot of Bitcoin that originally began as a joke). One German attacker managed to mine over $600,000 of Dogecoin from Synology boxes. It’s yet another reason why you shouldn’t enable remote administration on your devices unless absolutely necessary.follow link
Enter Dashboard, Expose, or Spaces Temporarily
Hold down F9, F10, F11, or F12 (or whatever you've set for the Expose and Spaces keyboard shortcuts) for a few seconds, and then release the key to enter and leave the appropriate mode without having to press the key again. This is particularly useful for Dashboard, in which you can check the contents of a widget and then return to your work with only a single key press.
