JPAUnit Release V0.1 - Mandela Day Release 2015

JPAUnit is a Java library for assisting with unit testing your JPA code. It  facilitates the initialisation of a database to a known state before commencing units test in Java.

IPv6 - Set Up An IPv6 LAN with Linux

Setting up an IPv6 LAN with Linux? Ever wondered how to do that? For years we have heard the dire predictions about the impending doom of IPv4 and the imminent arrival of IPv6.
