SVG delivering the graphs

If you have been using my app you should be familiar with my mode of delivery for the graphs. They are currently dynamically generated gif’s at the server side. While this is definitely serving the purpose the medium has its inherent drawbacks. I have been using a mix of stuff to get what I want like image maps which translate the mouse position on an image to the values on the graph, legends drawn into the image to give specific advices on an image, java script graphic libraires for overlaying ternd lines on the images etc.

I have been exploring the SVG standard which Firefox supports well. This is a well suited medium for delivery of information. Being a native XML format specifying the image, with good support for scripting features which allow for access to the native DOM of the image and manipulation at the client side, this gels well with the features that I need. Here are some screen shots

To preview this try this link. Please note this is strictly Firefox only feature not tried on IE with SVG plugins.

Dojo Toolkit

A wonderful piece of software!! The Dojo toolkit rocks, I recently tried it and have replaced my heavy drop downs (the ones which used to list all the active scripts on NSE) with an auto complete widget from Dojo. Similar to Google suggests uses AJAX and JSON to provide some wonderful speed up.

VMWare on Fedora Core

I recently downloaded the free vmware player from here and then setting it up ran into issues when the module was being compiled. First it was complaining about the kernel sources not being present, and then it started complaining about the kernel address space. Found this article right to the point on getting my problem solved.
