Apt-Pinning allows you to use multiple releases (e.g. stable, testing, and unstable) on your system and to specify when to install a package from which release. That way you can run a system based mostly on the stable release, but also install some newer packages from testing or unstable (or third-party repositories). falko Tue, 24 Mar 2009 12:27:55 GMT http://www.howtoforge.com/adding-and-updating-spamassassin-rulesets-with-rulesdujour This article explains how you can download additional SpamAssassin rulesets resp. automatically update these rulesets with a shell script called RulesDuJour.

This loadbalancer retrieves requested pages from two or more backend webservers and delivers them to the user's computer. Users get the impression that they deal with just one server (the loadbalancer) when in fact there are multiple systems behind the loadbalancer that process the users' requests. By using a loadbalancer, you can lower the load average on your webservers. One important feature of mod_proxy_balancer is that it can keep track of sessions which means that a single user always deals with the same backend webserver. Most websites are database-driven nowadays with user logins etc., and you'd get weird falko Tue, 29 May 2007 16:53:33 GMT http://www.howtoforge.com/apache2-how-to-redirect-users-to-mobile-or-normal-web-site-based-on-device-using-mod_rewrite Since the massive rise of smartphones and tablets like the iPhone, iPad, Android phones and tablets, BlackBerries, etc. you might have considered creating a mobile version of your web site.
