Online risk calculators are all the rage these days among public health groups trying to get us to change our unhealthful ways. The World Health Organization developed an online tool that lets you estimate your personal risk of cracking a hip in the next 10 years, for example. You just plug in data about yourself, your lifestyle, and your family medical history.
Some refrigerators can let you know when the door is open, or if the milk is past its sell-by date. They make ice at night during less expensive, off-peak energy hours. There are dishwashers that can contact a repairman.
It probably won't be long before you can become Facebook friends with your microwave.
The first microwave oven — the Radarange — weighed 750 pounds and was bought by a Cleveland restaurant in 1947 for $3,000. Later home models had a pull-out box for recipe cards. Paper recipe cards. So quaint.
If the past few months have taught us anything, it's that everything we do online leaves a digital trail. While it may seem like there's not much we can do about it, there are some tech companies that are working to obscure that trail a little bit, with a process known as encryption.

The bus-sized meteor that slammed into Russia in February, causing a massive shock-wave and injuring hundreds of people, sent a plume of dust into the stratosphere that circled the globe in just four days and lingered for months, NASA says.

He would be probably the first to wish you a happy International Geocaching Day. Geo what?
DAVE PREBECK: Geocaching is basically a high tech scavenger hunt.
SIMON: That's Dave Prebeck, president of NOVAGO, the Northern Virginia Geocaching organization.
PREBECK: We have people go out and hide something and then they post the latitude and longitude on a website - geocaching.com is the primary one - and then those of us with GPS's get the latitude and longitude from the site and go out looking for them.
Dolphins are washing ashore in alarming numbers in the Mid-Atlantic states this summer. More than 160 deaths of dolphins have been reported since early July and that's the worst fate in 26 years. Response teams from New York to Virginia are trying to determine just what's killing all these dolphins. Charlie Potter is working with one of those teams at the Virginia Aquarium and Marine Science Center.
In the digital world, almost everything you do to communicate leaves a trace. Often, emails are stored on servers even after they're deleted. Phone calls create logs detailing which numbers connected, when and for how long. Your mobile phone can create a record of where you are.
If you're a journalist trying to protect a confidential source, this is a very difficult world to work in.
