Keep your photos private on Facebook
Q. I'm worried about the photos I'm posting on Facebook. How can I make sure only my friends and family can see them?
A. Log in to your Facebook account. At the top right, click the icon with the padlock and three horizontal lines. Select "Who can see my stuff?" and then under "Who can see my future posts?" set it to "Friends." Now everything you post in the future, including photos, will be limited to your friends. Next, go under the padlock icon >> "Who can see my stuff?" >> "What do other people see on my timeline?" click the "View as" link. This shows you what your profile looks like to the public. You can easily see if any photos are visible that shouldn't be.
Uses for a spare tablet
Q. I just got a new tablet and I'm not sure what to do with my old one. Any suggestions besides selling it?
A. There's a lot you can do with a spare tablet. You could make it a guest computer for visitors. (After you wipe it clean, of course.) An app like Remote Mouse can make it a wireless controller for a computer. Photographers can use an app like SoftBox to turn a tablet into a customizable portrait light. Use it as a mobile cash register for your business with an add-on like Square. The sky is the limit.
Boost your Wi-Fi
Q. My Wi-Fi signal doesn't make it to the back room of my house. How can I extend the range?
A. Well, first, make sure your router is in a central location in the house. Put it high and away from walls and metal objects. If that doesn't help, it might be time for a new router. You'll want one with multiple-antenna 802.11n or, if your budget can support it, a router with 802.11ac. Find out if an 802.11ac router is worth your money. If you have a large house, you might pick up a Wi-Fi extender to expand the signal. Just note that it will drop your Wi-Fi speed in half.
Watching YouTube videos on your TV
Q. I'm streaming YouTube videos to my smart TV, but it's a pain finding them with the built-in keyboard. Is there a better way?
A. Actually, there is. When you're looking at YouTube videos on your computer, you'll see a clock icon in the lower right corner of the video player. Click this to add the video to your Watch Later list. Do this for however many videos you want. Then go over to your TV and load up the Watch Later list. It's as easy as that, and searching for videos on your computer is so much easier.
Check prices while shopping
Q. I realized too late that I paid more than I needed to for Christmas presents. How can I get better prices in the future?
A. You definitely want to stock up on price-comparison apps for the next time you go to the store. RedLaser, ShopSavvy and PriceGrabber are goods ones to start with. They let you scan product barcodes and show you where you can find items for less. Each one has cool extra features. PriceGrabber, for example, shows you the cost of the item including tax and shipping so you know how much you're really paying.
