Augmented Reality Interview for AOL News

I recently did an interview about Augmented Reality for an AOL News site ( A few years ago, I co-wrote a book about Augmented Reality that was based on the work of Dr. Mark Fiala—an old friend of mine and creator of the ARTag marker system.

The writer was interested in a number of AR applications that have started to make it into mainstream culture. For example, AR tattoos are apparently gaining popularity (see video below).

SharePoint 2010 Config Wizard Error

I was getting this error when trying to run the configuration wizard for the SharePoint 2010 RC Hyper-V Image.


In the wizard, I was specifying a domain account with sufficient permissions, but I still got the access denied error. The solution was quite simple, I had forgotten that I was logged into the machine as the local admin account—not a domain account. The config wizard needs to read some info about the domain account you’re using for the setup. When I switched users to my own domain account, the wizard ran successfully.

Here’s a snipped from the install log:

Task configdb has failed with an unknown exception 03/19/2010 06:38:14  9  ERR                    Exception: System.InvalidOperationException: An error occurred while getting information about the user SharePointAdmin at server internal: Access is denied
