Sharing your data on the Pachube site involves setting up an account, obtaining some ID numbers, downloading an additional Processing library, and running some lightly amended Processing code that pushes your temperature network data to the site.

You’ll need to sign up for a Pachube account at http://www.pachube.com/signup (see Figure 8-3). Accounts are free and require very little information, just a username, email address, and password to get going.

Once you are signed up, the first thing to do is register a new feed using the Register a Feed link on the home page. A feed is any collection of related data. For this project you’ll use manual mode, meaning that your program will manually contact the Pachube site every time there is data it wants to place there. Your feed will need a title, and you can optionally enter other descriptive information as you see fit (see Figure 8-4).
