Pachube is a website for easy sharing and retrieving of sensor data from all over the world. It has many benefits in its easy to use interface which enables user of the website to fast get connected and start sharing data. One thing that I felt lacked in the software though was to fast and easy get a complete overview of the most active sensor nodes among all the inactive and static that naturally occurs in this kind of open system.
The way searching is handled currently is that you do a search on a tag and it returns a multi paged list with all the corresponding feeds which takes a long time to look through and get an overview of. Datube gives you the same function to easily search data feeds containing a certain tag but shows its result by using movement to highlight changing sensor data over the last 24 hours. This easily sorts out the most changing feeds which you then can investigate deeper and see if they fit your intended use.
Next step is to bring in more search options to better narrow down the result and thus resulting in a shorter time from start searching to finding the desired content.
