An Agile Developer's workflow when SCRUM is used

Thu, 16 Oct 2008 23:05:11 GMT

If you are planning to start SCRUM at your company, you might need to train developers and QA to get into the mindset of an Agile developer. SCRUM is only successful when the developers and QA get into the habit of following the principles of SCRUM by heart. So, sometimes you need to offer training or do trial sprints to give some room to your developers how to get used to the working fashion of SCRUM. Giving them a handy workflow diagram that shows how they should work helps soothe the steep learning curve required for non-super star developers. I made such a workflow while I was teaching SCRUM at my friend's company. The following diagram was printed and hung over the desk of each and every developer to help them grasp the culture of SCRUM quickly.

Loading static content in ASP.NET pages from different domain for fast

Sat, 02 Aug 2008 02:20:41 GMT

Generally we put static content (images, css, js) of our website inside the same web project. Thus they get downloaded from the same domain like www.dropthings.com. As browser can only open two concurrent connections, all of these download only two at once. If you move the static content to a separate domain, browser can download more content in parallel and thus load the page faster. This HttpFilter parses the page output and automatically moves all static content links to a different domain as specified.

UFRAME: goodness of UpdatePanel and IFRAME combined

Tue, 27 May 2008 00:16:03 GMT

UFrame simulates the behavior of IFRAME on a DIV. Any page can be loaded inside a DIV and hyperlink navigation and form posts happen within the DIV. As a result, a regular page can start providing AJAX features without ever writing any AJAX code. ASP.NET MVC websites can now use UFrame instead of UpdatePanel.
