Welcome to FUH2.com, home of the official Hummer H2 salute. So...why all the fuss? Well, it breaks down like this: The H2 is the ultimate poseur vehicle. It has the chassis of a Chevy Tahoe and a body that looks like the original Hummer; i.e. it's a Chevy Tahoe in disguise. The H2 is a gas guzzler. Because it has a gross vehicle weight rating over 8500 lbs, the US government does not require it to meet federal fuel efficiency regulations. Hummer isn't even required to publish its fuel economy (owners indicate that they get around 10 mpg for normal use). So while our brothers and sisters are off in the Middle East risking their lives to secure America's fossil fuel future, H2 drivers are pissing away our "spoils of victory" during each trip to the grocery store.
The H2 is a polluter. Based on G.M.'s optimistic claim that it gets13 mpg, an H2 will produce 3.4 metric tons of carbon emissions in a typical year, nearly double that of G.M.'s Chevrolet Malibu sedan. The H2 is a death machine. You'd better hope that you don't collide with an H2 in your economy car. You can kiss your ass goodbye thanks to the H2's massive weight and raised bumpers. Too bad you couldn't afford an urban assault vehicle of your own. Or could you...? The H2 is a tax loophole. Under the current tax laws, business owners can deduct nearly half the cost of their H2s. If you are in the highest tax bracket, that's a tax savings of nearly $10,000! The government rewards you more savings for buying an H2 than you'd get for buying an electric car.

 

The enterprise-class Open Source LDAP server for Linux. It is hardened by real-world use, is full-featured, supports multi-master replication, and already handles many of the largest LDAP deployments in the world. The Fedora Directory Server can be downloaded for free and set up in less than an hour using the graphical console.

Includes integration with active directory. 

Cookie based web authentication and single sign on system designed for largish intranets under a single domain where many people run their own webservers (and you don't trust them all much).

On first connection, an untrusted webserver redirects new requests for restricted pages to the idcheck server (to be authenticated). The idcheck server takes and checks the users credentials and, if successful, redirects the users browser back to the page they requested. As it redirects, the server installs a private cookie (scoped only for the idcheck webserver) and a second cookie that acts as a session cookie for the untrusted webserver (which is checked for validity, over http against the idcheck server) when downloading subsequent pages.

When the user accesses another webserver that also has idcheck restricted pages he does not need to enter his credentials again because of the private idcheck cookie indicates that he has already authenticated and so can bypass the login form. This provides a single sign on environment for multiple webservers in a single domain..

Shibboleth is a system designed to exchange attributes across realms for the primary purpose of authorization. It provides a secure framework for one organization to transmit attributes about a web-browsing individual across security domains to another institution. In the primary usage case, when a user attempts to access a resource at a remote domain, the user's own home security domain can send certain information about that user to the service provider site in a trusted exchange. These attributes can then be used by the resource to help determine whether to grant the user access to the resource. The user may have the ability to decide whether to release specific attributes to certain sites by specifying personal Attribute Release Policies (ARP's), effectively preserving privacy while still granting access based on trusted information.
