Consumeter
Free and open source project for visualizing home economy. There are already other similar and more sophisticated services available on the web, like utdraget.se, but I created my own to keep it clean, simple and easy to customize. Another advantage is that you can run it locally and keep your finances to yourself.
Get the latest version from SourceForge:
http://sourceforge.net/projects/consumeter/
To run it you need the following:
- Apache web server
- PHP 5
- MySQL
- phpMyAdmin (or whatever database interface you prefer)
If you're running Ubuntu you can get 'em all like this:
After downloading and installing all packages you need to
setup the database by running the database_init.sql
file in the site root directory.
