10 cool web development related articles in 2007

Here's a list of 10 cool ASP.NET, AJAX and web development related articles and blog posts that I have written this year that you might want to take a look:

13 disasters for production website and their solutions
Talks about 13 production disasters that can happen to any website any time and bring down your business.

Build Google IG like Ajax Start Page in 7 days using ASP.NET Ajax and .NET 3.0
This block buster article shows how ASP.NET AJAX, Linq to XML, Linq to SQL and Workflow Foundation can be used to create a Google IG like start page in just 7 nights. Learn how to put together such hot technologies into one project and make a production site out of it.

Serve extensionless URL from ASP.NET without using ISAPI module or IIS 6 Wildcard mapping
Currently there are only two ways to service extentionless URL like www.pageflakes.com/omar that hits something besides the default document - use a custom ISAPI module or use IIS 6 wildcard mapping. Both has performance and scalability problems because both intercepts each and every hit. Learn how you can solve it by using a custom 404 handler.

Request format is unrecognized for URL unexpectedly ending in /SomeWebServiceMethod
Since ASP.NET AJAX 1.0 release, Microsoft prevented JSON hijacking by adding a special content type header. But this caused us some trouble.

Cleanup inactive anonymous users from ASP.NET Membership Tables
When you store anonymous user profile using ASP.NET Membership provider and Anonymous Identification provider, you soon end up with lots of idle anonymous user data where those users never come back. We (Pageflakes) went through a lot of difficulty keeping our database size down as we allow anonymous users to do almost everything that a registered user can do. This introduces scalability challenge. See how we solved this problem.

Prevent Denial of Service (DOS) attacks in your web application
Web applications can be brought down to its knees by hitting the site repeatedly or by calling expensive webservices randomly. Anyone can write a simple loop that hits a webserver very frequently from a high bandwidth connectivity and bring your production server down. See how to prevent such application level DOS attacks.

ASP.NET Ajax Extender for multi-column widget drag & drop
It's an ASP.NET AJAX extender that allows Pageflakes style drag & drop functionality between columns and rows.

ASP.NET Ajax in-depth performance analysis
While building an open source start page using ASP.NET AJAX, I have done a lot of performance analysis on AJAX framework in order to improve first time load and perceived speed of javascript rich pages. Check out my analysis.

Make a surveillance application which captures desktop and then emails you as attachment
Some time back I needed to capture a certain computers desktop in order to find out what that user is doing every day. So, I made a .NET 2.0 Winforms Application which stays on system tray (optional) and capture the desktop in given time interval (say every 60 secs) and emailed the captured images to me as message attachment (say every 30 mins).


Today I received MVP award for the 3rd time on Visual C#. Thanks to Microsoft for the award and setting up my new blog here. I will continue both my MVPS Blog and this blog from now on.

Pageflakes is my favorite mash up site. I ought to make a pageflake for Stickam, my favorite web site, although my custom Yahoo Widget serves me well. I'm currently studying ASP.NET web parts to create database management mash ups. There are no decent examples of this but I would like a portal for my data.
