This is a very simple approach to doing role-based access control with Neo4j. It is optimistic, in the sense that all items are assumed to be world-accessible unless they have specific constraints. Item visibility can be constrained to either individual users or all users who belong to a role. Roles are also hierarchical, so can inherit privileges from other roles.
First, lets create our basic example data:
Look at LSB init scripts for more information.
Copy to /etc/init.d:
# replace "$YOUR_SERVICE_NAME" with your service's name (whenever it's not enough obvious)
This note tries to document the output of PrintCompilation flag in HotSpot VM. It was originally intended to be a reply to a blog post on PrintCompilation from Stephen Colebourne. It's kind of grown too big to fit as a reply, so I'm putting it here.
