Ecologineers v2.1

Our web application has come a long way since version 1.0. We've done a lot of bug fixes and added a couple of new pages that gives user's useful information. One of the pages we've added was the Home page. This is simply an introduction of our web application and what the other pages does. The second page that we added is the StopLight page. This page provides the user information depending on the carbon intensity of SIM_OAHU_GRID. It has four categories, green, yellow, red, and no data. This gives the user an idea of when they should be plugging their devices to the outlet. The third page is just a modified version 1.0 grid info page that displays the carbon intensity chart for SIM_OAHU_GRID. The user can now select a start and end date for the time period that they want a chart generated for. The user can also select from a pull down menu SIM_OAHU_GRID's sub-sources.

We tried to implement some extra credit features to our web application. One of them is the addition of nice urls for the links. Instead of the wicket gibberish url that it displays in the address bar, it now shows a nice bookmark-able link that is easier to remember. This means that the StopLight page is now called "stoplight" and the GridInfo page is now called "gridinfo" in the address bar of our browser. We also added an ajax page refresh for the StopLight page. What it does is it refreshes the page every minute so that it can update the users quickly instead of waiting for another hour to manually refresh the page.

Working on this application thought me some valuable lessons. It's clear that one person can only do so much. After trying to implement something for hours, I had to walk away from it and pass it to one of my group members. It's also nice to learn something new. The wicket framework can be really useful if I continue to learn it.
