I know you’re not a fan of Facebook, but I’m hoping you can help me. I blocked the news feeds of a friend a long time ago and now I’d like to reverse that. The only problem is that I don’t know how to remove the block.Log into your Facebook account and scroll to the bottom of the news feed until you see the Older Posts button. Directly across from that, click Edit Options. In the window that appears you will see the friends and organizations whose news postings you have blocked. Click the little X next to each name you wish to unblock. When you’re done unblocking, click Save. To unblock a Facebook friend, after logging in, choose Privacy Settings from the drop-down menu in the upper right-hand corner, followed by Manage Blocking. Under Block Users, click the blue Unblock next to the name of any blocked individual.You are correct that I am not a fan of Facebook, Twitter or myriad other social media platforms for a variety of reasons. (Hint: Massive waste of time.) If you would like to read my pithy observations on this subject, please visit http://bit.ly/15fZ7rO. It drives me crazy when I accidentally turn my Caps Lock on while typing, only to discover that I’ve been typing in ALL CAPS for several sentences. I know there is a way to have it beep at me when I do that. Can you help preserve what little sanity I have left, Mr. M?Toggle Keys will be happy to beep at you when you turn on the Caps Lock, Scroll Lock or Num Lock keys. To do this, go to your Control Panel and double-click Accessibility Options > Keyboard tab. Locate the ToggleKeys section and click to select Use ToggleKeys, followed by OK. In the alternative, click Start > Search and enter “ToggleKeys.” Can you explain what a “flop” is? It came up in my computing class but I was too embarrassed to ask what it means.Whenever I hear the word “flop,” I think of Ishtar or Gigli, but maybe that’s just me. Within the context of computing, FLOPS is an acronym derived from FLoating point Operations Per Second. It is a measure of a computer’s performance, loosely interpreted as instructions per second.The fastest computer today is China’s supercomputer, Tianhe-1A (catchy name), which can achieve a speed of three petaFLOPS. A petaFLOP is a thousand trillion (also known as a bajillion) operations per second, so that’s a whole lotta floppin’. By comparison, a typical desk calculator slogs along at a laggardly 10 FLOPS. Pulleeeze!
