How to really disable event firing in sharepoint

One of the things I found out the hard way while programming event handlers in sharepoint is that you have to wrap your update() or delete() functions with the disableeventfiring function individually, for example:

this will work:
base.DisableEventFiring();
item.update();
base.EnableEventFiring();

this will NOT work:
base.DisableEventFiring();
item.update();
item.delete();
base.EnableEventFiring();

So the moral of the story is, only do one event triggering action at a time, do not try to do 2 or more within one wrapper.

Changing Content Type Hub URL

Change the Hub URL through powershell by using: Set-SPMetadataServiceApplication -Identity " " -HubURI " " For Ex: Set-SPMetadataServiceApplication -Identity "Managed Metadata Service" -HubURI "http://contenttype.Domain.Com" When you try to do this you get this rather scary message: This is SharePoint telling you that this is a major thing so be careful!
