MySpace is sharing an open source project named MySpace’s Performance Tracker which is an Internet Explorer plugin for capturing and measuring possible bottlenecks on webpages.

The plugin is a great helper to developers for:

• measure the CPU hit and memory footprint of your pages
• reviewing screenshots of the page while it renders
• reviewing rendered HTML on each point of the page’s lifecycle
• viewing estimates of the time it takes to render each section of the page in different connection speeds
• validating the content of pages against a set of proven “best practice” rules of web development. 

P.S. The tool is currently in pre-alpha state.

For every web designer & developer, refreshing the browsers to see the updates we make is a very common action.

XRefresh is a solution, specifically built for easing this process, which automatically refreshes browsers once an update to a file in our project folder is done.

It comes with 2 parts: a browser plugin (both for Firefox & IE) and an application (for Windows & Mac) which watches the changes made in the folders we mentioned.

Although it is handy for systems with one monitor, the best environment will probably be two monitors where the IDE & the browsers runs on each.

P.S. For Firefox, it requires Firebug to be installed.

DD_roundies is another rounded corners solution that is very easy to implement & cross-browser compliant.

This rounded corners script doesn’t use any images, works in IE6 without AlphaImageLoader & lightweight (3.62kb compressed).

Radius of the corners are not fixed & can be defined.

As the major problem for rounded corners lies beneath IE, this rounded corners script uses VML (inspired from Jonathan Snook’s solution). A possible future problem is IE8 -currently- does not support VML.
