hide a node from node author in view
Without Code:

To adjust views to show/hide author content...


under Advanced Tab create a Relationship, Content:Author, Require this field
create a new Filter, User:Current, Relationship Author(or whatever name you gave the relationship), Is the logged in user -> No


This will compare the author of the content to the currently logged in user and only show the content if they don't match. This method can be used to show only content by the current user by changing the 'Is the logged in user' -> Yes
