Javascript - Monitoring changes for object attributes
Let me disclaim straight away, this blog post is based on blatant copy of Eli Grey's object.watch gist on GitHub. The small script proved so useful to me in a tight situation (I think last to last week) that with full acknowledgement of this being his work, I wanted to roll it up into a blog post.
Javascript - Loading social plugins dynamically on the page after the page has loaded
The last couple of days saw page load times for my website increase significantly. As I checked my server logs for hints of potential issues, nothing seemed abnormal.

ExtJs and Ext.Net - Creating Ext.Net server components for custom ExtJs javascript components

It exposes almost all ExtJs toolkit classes server-side in ASP.NET and many of the popular extensions too. In addition, it provides own custom components that are useful (e.g. MultiCombo, Linkbutton etc).
IE 9 Developer Tools - Inspecting elements might need an F5 key press
This has happened to me enough times now that I would think of publishing the issue and its resolution in a blog post. And the issue relates to inspecting elements on a web-page using Internat Explorer 9's Developer Tools.
