Using the Request.ServerVariables Object - http://www.4guysfromrolla.com/webtech/092298-3.shtml Active Server Pages exposes an object called ServerVariables, which is part of the Request object.

You can use the ServerVariables along with IIS's directory sercurity options to determine who is currently accessing your site.

This article includes a question and answer from the Activer Server Pages mailing list, as well as an excerpt from the Visual InterDev 1.0 help files detailing all of the properties of the ServerVariables object.
Visual Representation of SQL Joins - http://www.codeproject.com/Articles/33052/Visual-Representation-of-SQL-Joins - I'm a pretty visual person. Things seem to make more sense as a picture.

Some had good diagrams but lacked completeness (they didn't have all the possible JOINs), and some were just plain terrible. So, I decided to create my own and write an article about it.
