Tech Tips

Get HD for Free


All of the major TV networks currently broadcast HD video over the air and in better quality than what you likely receive from your cable/satellite company. And despite any techno-babble you may read, you can receive HD television signals over the air using a regular old TV antenna (as long as your HDTV has a built-in tuner, which most do). To figure out what channels are available in your area, and in what direction your antenna should be pointing, consult antennaweb.org. Hit up hdtvantennalabs.com for reviews of antennas, how-to guides, and helpful forums.

Tech Tips

Quickly Switch Apps on a Palm Pre


Rather than opening your Palm Pre's Card View function to sort through all of your open apps, you can simply swipe back and forth between running apps. Go to the Launcher and select Screen & Lock. Under the heading 'Advanced Gestures,' slide the Switch Applications option from Off to On. Now, when you have several apps open, you can swipe left across the length of the gesture area to quickly flip to the last app you used, or swipe to the right to view other running apps.

Tech Tips

Keep Two Computers Synced


Keep all of your photo, video, audio, and data files up-to-date between your laptop and desktop by using syncing software. If you have a Windows PC, SyncBack is a freeware backup utility that lets you merge or overwrite data between two sources. Mac users who are comfortable using the Terminal may enjoy the free rsync utility, but the rest of us will prefer ChronoSync, a $40 app that lets you easily and seamlessly backup, or sync between two computers. (It even allows you to sync between a Mac and a PC.)

Tech Tips

Turn Pesky PDFs Into Word Docs


Believe it or not, you can take the pain-in-the-ass out of PDFs. Though most PDFs can't be edited, there is one freebie workaround if you're in a pinch. Go to pdftoword.com, upload your PDF, and enter the format to which you'd like it converted. Within an hour or two, you'll get an e-mail containing a regular old Word or RTF file that you can fully edit. If you're in a hurry, the site offers a pro software version that lets you do PDF conversion on your own computer.

Tech Tips

Swap Dead-Tree Catalogs for iCatalogs


Earn the gratitude of pine forests and beleaguered postal carriers the world over by signing up to receive electronic catalogs instead of paper ones. CatalogChoice.org is a godsend in that you can quickly and easily sign up. When you enter the customer data from the address labels of catalogs you receive, you'll get the option of either signing up for an iCatalog or just canceling delivery altogether. Granted, it takes several weeks to kick in, and some jerky retailers simply won't budge. But if you're the type who gets deluged with catalogs every season, you'll quickly notice a difference.

Tech Tips

Speedy Hard Drive = Speedier PC


Other than adding as much RAM as possible, a quick, relatively cheap way to gain noticeably better performance from your aging PC is to upgrade the hard drive to a faster model. The faster a hard drive spins (measured in revolutions per minute or rpm), the more quickly it can access data and pass it back and forth to the processor. For desktop computers, you should get at least a 7,200 rpm drive, although 10,000 rpm is ideal. For laptops, 5,400 rpm (standard on new machines) should do the trick, but 7,200 rpm is recommended. As always, before buying, check to make sure your computer can handle the specs of whatever drive you select.

Tech Tips

Donate Old Cell Phones to Help Others


Rather than sell or recycle your old cell phone (or throw away, God forbid!), consider donating it to one of the many charitable organizations that put them to good use. Hit charityguide.org for a list and description of places that accept used cell phones. And as always, make sure to delete all personal information from your phone before putting it in the mail (including the memory card). Usually, you can simply go to Settings/Security and choose to restore your phone to factory settings. If not, Google for instructions.

Tech Tips

Take iPhone Screenshots


If you need the content of a Web page but can't be bothered to cut and paste text, or want to memorialize your amazing word stack on Bananagrams, use your iPhone's built-in ability to take screenshots. Hold down the Home button, and then press and release the Sleep button (on top). Once you hear the familiar shutter sound effect, you'll be able to access your new snaps in your Photos collection. It's especially useful for taking self-portraits, a notoriously difficult task since it require that you hit a touchscreen button without seeing the screen. Just go to the Camera app, and then repeat the above steps. (The downside is that your shot will, of course, include the image of the shutter button bar, too).

Tech Tips

The Easy Way to Sell Old Gadgets


If you aren't willing to donate old electronics to a non-profit organization, and don't feel like going through the hassle of haggling with buyers on eBay, try one of these services:
  • Gazelle.com (formerly Second Rotation) lets you input the condition of and details about your electronics. Then, based on current auction market prices, it makes you an offer. If you accept, administrators will send you a box, confirm receipt of the package, and then finalize the offer; if you decline, they'll send your stuff back for free.
  • Best Buy's trade-in program is two-fold. You can exchange products purchased at Best Buy for cash or credit. (After you've input details online, the site will give you an offer, which you can print out and bring to a local store.) Alternatively, if you purchased your gadget at another store, you can get an estimate, print out the label, toss the package in the mail, and receive your gift card or check within two weeks.

Tech Tips

Ultimate iPhone Keyboard Shortcut


Instantly jump to the top of almost any scrollable iPhone app by tapping the status bar at the top of the screen (where the clock is). It's especially handy for when you scroll 195 messages deep into your e-mail inbox and want to go to your newest message again. It works in virtually every Apple-branded app (and some third-party ones, as well), and works in contacts, Safari Web pages, and within e-mails, themselves.

Tech Tips

Thaw Your Frozen iPod



Impress your less tech-savvy friends by rebooting their seemingly "bricked," or frozen, iPod. For older, click-wheel versions: Toggle the Hold switch from on to off, then press and hold the Menu and Center buttons simultaneously until the Apple logo appears. For iPod Touches and iPhones, simultaneously press the Sleep button (on top) and Home button until the Apple logo appears. (Ignore the option to shut it down and keep holding.) Ta-da! You just saved someone a couple hundies!

Tech Tips

Share Your Internet Connection Wirelessly, Without a Router


If you have more than one computer or a Wi-Fi phone at home, but no Wi-Fi router, you can still share your Internet connection wirelessly from the PC that's hooked to your modem. The gist is that the main PC broadcasts its Internet connection over its Wi-Fi card and thus acts like a router itself, allowing other devices to connect. For step-by-step instructions, click here for Windows Vista PCs, here for Windows XP, and here for Macs.

Tech Tips

Give Retired Hard Drives a Job


Rather than throwing away that old, dusty hard drive gathering dust in the back of a drawer, put it to work as a quick and easy backup storage unit. In lieu of dedicated external hard drives, companies like Brando and Newertech offer cheap adapter cables and hard drive docking stations for USB or Firewire, allowing you to plug in an SATA drive and instantly use it like a regular old external hard drive.

Tech Tips

Supercharge Your DVR's Hard Drive

One of the curses of HD DVRs is that, when recording HD video, they fill up terribly quickly. But, depending on your cable or satellite provider, and the model of box you have (check with your provider), you can quickly and cheaply upgrade your capacity. First, get hold of a completely empty SATA USB hard drive. Unplug the power cord of your set-top box, plug in the drive (the bigger the better), turn on the set-top box, and follow the onscreen directions to wipe and format your drive. Unfortunately, you won't be able to view your recordings on other DVRs or PCs, but you will be able to record vast amounts of programming.

Tech Tips

Immunize Your Cell Phone From Telemarketers


It used to be that cell phones were safe from the clutches of telemarketers, but sadly that is the case no longer. The good news is that you can submit your cell phone number to the national Do Not Call Registry, even if you no longer have a landline phone. Hit donotcall.gov and within 31 days you should be free from marketing call lists for good. If not, report the offending caller on the same site. If you're of the lawsuit-happy, litigious type, start collecting evidence and take 'em to court. At $500 a call, it's not a bad hobby.
