• Visit your timeline on Facebook (just click your name at the top of any Facebook page), click the Activity Log button (it’s the one beneath your jumbo-sized “cover” photo), then click the “Likes” link in the left-hand column.


Not only can you review your past Facebook “likes,” you can hide or even “unlike” them.
• In a moment or so, you should see a list of all your various “likes,” starting with the most recent. To quickly jump down to an earlier month or year, click the column of dates to the right of your “likes” list.
• Next to each of your likes, you’ll see a pair of icons. The first icon represents the privacy setting for the “like” in question: a little globe for “public,” a pair of silhouettes for “friends,” a gear for “custom,” and a padlock for “only me.” To change the privacy setting, click the icon and select a new option.
• The second icon looks like a small pencil. Click the icon to either “allow” or hide a “like” from your timeline—or, if you wish, to “unlike” an old “like” altogether.
• All done? If so, you can simply dive back into your Facebook feeds; no need to click a “Save changes” button.

If you’re in the U.S. or Canada and you’re a Gmail user, heads up: you can make free phone calls through your PC or Mac to any domestic cell phone or landline. As always, though, there are a few ifs, ands, and buts.

Just click the headset icon to launch Gmail’s phone dialer.

1. Only U.S. & Canadian Gmail users can make free calls

2. Domestic calls over Gmail are free through the end of 2013 only

3. If you want to make international calls with the Gmail dialer, you’ll have to pay up

4. You don’t need a headset to make Gmail voice calls

Click a phone number in a Gmail message and the dialer will pop up automatically.

5. You can click any phone number in a Gmail message to dial

6. You must make your free calls through the Gmail interface on your computer

7. Replacing your landline or cell phone with Gmail isn’t the best idea

8. You can receive calls through Gmail if you have a Google Voice number

Tip

For Mac:

• First, select the files you want to compress into an archive. You can also select an existing folder if you wish, or even a combination of files and folders.
• Next, right-click the selected files and/or folders and select “Compress” from the pop-up menu.
• In a few seconds or so (depending on the size of the files you’re compressing), a file titled “Archive.zip”—containing copies of all the files and folders you just compressed—will appear on your desktop. Meanwhile, your original, uncompressed files will be sitting right where you left them.
• Go ahead and rename the archive file (click its icon, click its name, and then start typing), then feel free to move it anywhere on your hard drive or send it to a friend.
• To “unzip” the file, simply double-click it; when you do, your Mac will decompress the archive automatically.

A simple right-click is all it takes to create a “zip” archive in Windows.

For Windows:

• As on a Mac, first select the files and/or folders you want to stuff into a zip archive.
• Right-click the selected files, select “Send to” from the pop-up menu, then select “Compressed (zipped) Folder” from the secondary menu.
• After a few seconds, a file titled “New Compressed (zipped) Folder” will appear, containing copies of all your zipped files. If you want to rename the archive, now’s a good time to do so (right-click, then select “Rename” from the menu).
• Unlike on a Mac, Windows will let you take a quick peek at the files compressed into a zip archive; just open the archive folder to see a list of your archived files. Keep in mind, though, that you won’t be able to preview the contents of a particular file.
• Want to unzip your archive? Right-click it and select “Extract all,” or open the archive folder and click the “Extract all files” button near the top of the window.
• You can also pluck individual files out of the archive, if you wish. Just open the archive folder, select a file, and drag it onto your desktop.

With all the hype over iCloud, it’s easy to forget that there’s a limited amount of “local” storage for all your apps, photos, music, videos, and other data.

• Tap the Settings icon on your iPhone (or iPad) home screen, then tap General, and finally Usage (it’s the third option from the top).
• Next, you’ll arrive at the Usage screen—and at the very top, you’ll see how much storage space is left on your iPhone, in gigabytes. After a few seconds, you’ll get a detailed list of the biggest storage hogs on your device, in descending order.
• See a jumbo-sized app that you could live without? Tap its name, then tap the red “Delete App” button. If you ever have a change of heart, you can re-download any free or purchased apps from the App Store.


You can delete specific apps and videos directly from the Usage screen.
• Photos and videos shot with the iPhone’s camera may also be among the biggest storage hogs on your iPhone, particularly if you rarely (or never) delete snapshots from the Camera Roll. You can delete photos one-by-one from the Photos app (just tap Edit, Delete), or you can zap all your photos in one swipe once you tap the “Photos & Camera” entry from the Usage screen. Keep in mind, though, that any photos you delete will be gone for good—that is, unless you’ve synced them with iTunes or uploaded them to your Photo Stream in iCloud.
• Movies and TV shows can be deleted one-by-one from the Usage screen by selecting the Videos entry and tapping the Edit button; music, however, can only be wiped all at once, unless you start swiping from the Music app. (By the way: iTunes Match storage is managed automatically by your iPhone, which means specific tracks can’t be deleted individually. Strange, I know, but that’s the way it is for now.) And again, remember that you can always re-download and movies, TV shows, or music purchased through the App Store.
