The only additional, required configuration is a back-end Perl script that stores the annotations
• The Art of Metaprogramming using Scheme — One of the most under-used programming techniques — Metaprogramming — programming with code generators or writing programs that themselves write code, has many uses in large-scale computer programming. This article shows you some tools needed to do Metaprogramming in Scheme, as well as provide several metaprogramming examples. To determine which problems are best solved with a code-generating programs, take a look at this introduction to Metaprogramming article, which teaches you why metaprogramming is necessary.
• LDAP-Based Authentication for Samba — In this tutorial, learn how to install and configure Samba as a primary domain controller with a secure LDAP-based authentication mechanism.
