These are my links for 23 nov 2011 through 30 nov 2011:

• BILL – Bill strives to be a solution for developing applications which can be run on platforms with limited resources (e.g. embedded systems) on top of the GNU Bash shell, with a focus on quality and reusability of shell code.
• Check_whois – Use this plugin with Nagios to be notified when a domain is about to expire.
• TIP: Debug squid ACL matches – The FreeBSD Forums – For tricky squid ACL troubleshooting situations, it is helpful to be able to see which access control entries a request matches and does not match. This information can be discovered easily using squid's debugging facility.
