Hi,
I'm going to make myself look stupid, but hey - it's all learning!
Can anyone recommend a place to learn more aobut the BitWise math functions,
the CF Docs just explain how to use the function and not what they do - and
righly so.
Anyone recommend a resource for me to learn from?
Ben.

This has been my preferred method of managing roles and authorizations for
years, regardless of language. By using well-named constants to represent
the
values for each security level, you make your code very easy to interpret.
Here's the next step I use for byte-code user customization: create a table
that holds menu entries. Each record contains a menu item's label, action,
etc., and a byte code that reflects which user roles (or security levels)
have
access to that menu item. Now you can use a query against the table to
dynamically generate menus depending on what authorizations the user has.
What's more, adding or removing capabilities from a role becomes a simple
matter of changing the bytecode value in the table, rather than editing a
bunch
of code.
