That was a pretty good "Intro to Facebook" workshop for about 40 PQMug members last night. Two things that came up were how to deactivate your account, and how to change your language to Pirate. For the latter, click the triangular drop down menu at your far right, go to settings, choose General, select language, and save. Yarrrr!
I must have inadvertently turned on 'Do Not Disturb' mode on my iPhone 4S a couple months ago, because my phone seemed to randomly stop ringing for most phone calls and text messages.
That was OK for the most part, because I had more or less stopped answering my phone anyway and no text message was ever so important that it couldn't wait a few minutes for me to visually check my screen. Still, it didn't 
make sense that some calls and messages got through while others did not. And as one who has 50 + custom ring and text tones, I was missing out on my personal symphony
'Do Not Disturb' mode is available to you through either the Control Center, or with more options through the main Settings page in IOS 7. You can customize which calls and texts will ring through from either your phone favourites, or any group in your address book.
Keep in mind the calls and texts are still going to voicemail, and available visually on the screen, your phone just won't alert you through the speaker. You can schedule when it kicks in, say from 5:00 pm till 9:00 am and buy yourself some peace and quiet, while keeping closely, if not constantly connected.
Backing up your hard drive has never been easier, thanks to the software Apple has been including with your Operating System since Leopard 10.5.
I've done it myself, more than once, it's true. I've had hard drives fail on me without having a back-up of any kind. It was devastating, but eventually I learned, and now I keep redundant back-ups of all my data, thanks to the affordability of external hard drives and the native Time Machine software. Still, I see it every week, and my un-scientific study shows a good 40-60% of people still don't keep a good back-up.
Here's how easy it is to do: 
Seriously, it's that easy. In operating systems Mountain Lion 10.8 and previous, you don't even have to partition the disk, just click yes and ignore. In Mavericks you will have to partition the hard drive as Mac OS Extended (journaled) in Disk Utility, but the software will lead you like an ox by the nose through every step.
The beauty of Time Machine, is that you can access old files that you've changed in the past, and restore the old configuration of that file to the present date. Consider if you've changed your iPhoto library, or deleted an important email, or edited a movie, document or Garageband file. Also, if your hard drive should fail, and the probability of that is 100%, you can restore your entire system, docs, and network settings from that most recent Time Machine back-up.
Lots of emails this week about the new Adobe Flash update and how to install it. They seem to update this plugin every 4 to 6 weeks, and it's essential to many online services like YouTube videos and other sites.
First, go directly to the Adobe.com website and navigate to Downloads.
Select the Adobe Flash update and click to download.
Now this is where most people get tripped up. After downloading the software, you still have to go through several steps to complete the install. Locate the update .dmg (disk mounted image) file in your downloads folder. Double click to launch the installer.
Choose the volume where you wish to install the software (your Macintosh HD) and follow the prompts the installer presents. It will require that you close any browsers, Safari, Firefox etc., before continuing.
You also have to agree to the software terms and conditions.
Once you've completed all of these steps, you should be good to go.
