Nos mandan un artículo sobre como implementar esquemas de Fail-over en sistemas AIX. Independientemente del operativo que menciona, se me hace una buena referencia introductoria a esquemas de Fail-over para cualquier sistema operativo:
PowerHA for AIX is the new name for HACMP (High Availability Cluster Multiprocessing). HACMP is an application that makes system fault resilient and reduces downtime of applications. This article introduces PowerHA and provides a detailed explanation of how to configure a two node cluster. This document is very useful for understanding PowerHA and setting up a two node cluster.

Nosn mandan un artículo introductorio a Bazaar, que es un sistema controlador de versiones tipo CVS, Subversion, GIT, etc.

Leo en Slashdot una nota sobre la intención del gobierno de la ciudad de León, Guanajuato, de colocar lectores de iris en toda la ciudad:

(GRI) announced today that it is rolling out its iris scanning technology to create what it calls “the most secure city in the world.” In a partnership with Leon — one of the largest cities in Mexico, with a population of more than a million — GRI will fill the city with eye-scanners. That will help law enforcement revolutionize the way we live — not to mention marketers.
