Tech site Ars Technica runs down the basics of securing your home wireless network with the most secure and up-to-date methods. The main takeaway is that when you enable encryption on your wireless router, use WPA encryption instead of WEP, because it's better and stronger.

The tutorial requires some command line work, but it's spelled out and explained pretty thoroughly. Photo by MShades.

It’s really important for me to know that my kids are safe with the nanny. I set up a hidden nanny camera so I can easily monitor my kids. I come home from work and get to see everything that happened the whole day. Any wrongdoings will definitely be caught on tape!
