Q: I'll be traveling over the holidays and prefer to use Wi-Fi instead of my cellular connection. How can I find free Wi-Fi connections?

A: Wi-Fi is definitely the way to go when you travel. You can kill time at the airport or on the road, and you can keep in touch with your family. But you need a good hot spot so you avoid those cellular data charges. There are some great programs and online services that can find the best free Wi-Fi. Try The Wi-Fi FreeSpot Directory, JiWire (and the JiWire App), and Connectify. All three will help you connect for free to the Web.

Q: I have a Kindle app on my smartphone to download e-books from Amazon. Now, I'm looking at buying an e-reader. Will other e-readers be compatible with my e-books?

A: Not every e-reader supports the same e-book formats. E-readers are getting better — most support the e-book standard ePub, for instance. However, Amazon is mostly sticking with its proprietary, copy-protected AZW format. You can only use e-books in that format with the Kindle program and Kindle e-readers.

This happened partly because people weren't careful enough with their Facebook profile settings. Here's what you can do: Start by regularly checking your own Facebook privacy settings. Try to strike a balance between being open with your friends and family and yet not becoming a target for stalkers and identity thieves. For more guidance on privacy settings, go to
