One more collaboration tool - SharedView

I have been using various remote assistance / collaboration tools in Live Messenger, Unyte, WebEx, GoToMeeting, QQ etc for long time due to my job and business nature, and it's good to hear that Microsoft provide a beta version of the SharedView tool.

Microsoft SharedView Beta - is a fast and easy way to share documents and screen views with small groups (15 max) of friends or coworkers; anytime, anywhere. Use SharedView to put your heads together and collaborate.

Unique and non unique index in SQL server

A developer asked me a question yesterday about what's the difference of unique and non unique index in a DB table. I then google and redirect him to this short and clean article: http://www.w3schools.com/sql/sql_create.asp 

It's good to recall:

Updating a table containing indexes takes more time than updating a table without, this is because the indexes also need an update. So, it is a good idea to create indexes only on columns that are often used for a search.
