Are you a Linux user who has ever wanted to turn on the lights in your house, or open and close the curtains, while away on holiday? Want to be able to play the same music in every room, controlled from your laptop or mobile phone? Do you want to do these things without an expensive off-the-shelf kit | CHAPTER 6 DATA SOURCES If you d prefer for them to go into your traditional Linux mail box then you can change the path to the following path var mail steev You can then retrieve them like this and watch the system download the e-mails getmail -r Some services notably Google Mail do not allow you to download all your e-mails at once if there are a lot of them.

Although communications generally remain public it is possible to create a list of users so that members of the same family can follow each other in private. One thing that Twitter has succeeded in doing better than most social sites is that it has not deviated from its original microblogging ideals meaning that the APIs to query and control the feeds have remained consistent. This makes it easy for you or your house to tweet information to your feeds or for the house to process them and take some sort of action based upon it. In all cases however you will have to manually sign up for an account on behalf of your house. 208 CHAPTER 6 DATA SOURCES
