Change file and folder permissions in OSX

So this past weekend I ran into something I haven't had to deal with on my mac, and that is file and folder permissions. On our iMac I have an account, and my wife has an account. This way we have our own profiles, playlists, and whatever else we want that is customized to her individual needs on the iMac. Well, the other day my wife asked if we could centralize our iTunes music. "Sure, why not." I said and hopped right to it.

T-SQL script to find transactions that are blocking

Error adding a user to the Participant Administration view

Working with users and user information in Windchill can be a pain depending on how your system is setup to authenticate.

From time to time the information in AD will need to change. An employee's name will change, or a contractor converts over to a full time employee. If a situation like this occurs you will most likely run into an error like the one below if you attempt to add the user's account to the Participant Administration screen.
