If This Then That (IFTTT) will put the internet to work for you with little ‘recipes’ that can automatically update your social profiles or send you an alert.

If you ride your bike into work you could set up a “recipe” to place an event in your Google Calendar when the weather in your area is “Clear”. It will also give you a temperature so you have an indication of what to wear/expect. Just sign up at ifttt.com and if you have a google account you can use your google account to log in.
