Databases integration testing strategies with Python

The Ceilometer project supports various database backend that can be used as storage. Among them are MongoDB, SQLite MySQL, PostgreSQL, HBase, DB2… All Ceilometer's code is unit tested, but when dealing with external storage services, one cannot be sure that the code is really working.

OpenStack meets Lisp: cl-openstack-client

A month ago, a mail hit the OpenStack mailing list entitled "The OpenStack Community Welcomes Developers in All Programming Languages". You may know that OpenStack is essentially built using Python, and therefore it is the reference language for the client libraries implementations. As a Lisp and OpenStack practitioner, I used this excuse to build a challenge for myself: let's prove this point by bringing Lisp into OpenStack!
