using UUIDs as primary keys in MySQL

Using uuids as primary keys efficiently in MySQL: see this Store UUID in an optimized way, it has benchmarks and everything you might need; apparently their way is a bit more efficient than using large integers and a lot more efficient than using the UUID strings.

Also interesting Storing UUID Values in MySQL Tables.

amusing Mojolicious error


Can't use string ("Zug::CMS::Admin::Users") as a HASH ref while "strict refs" in use
at Mojo::Base::__ANON__(~/perl5/perlbrew/perls/perl-5.20.2/lib/site_perl/5.20.3/Mojo/Base.pm line 59



The problem was I had a new sub in "Zug::CMS::Admin::Users" ; renamed the new and everything works fine.
