At the Forge - Integrating OpenID
OpenID is a simple but powerful idea that is slowly but surely transforming the way we manage identities on the Internet. A growing number of applications use OpenID, and it is becoming increasingly popular among users as well.
Adding OpenID to an application does not need to be complicated or difficult. As I show this month, incorporating OpenID into a Rails application requires understanding one particular Ruby object, namely OpenID::Consumer, and the odd, redirect-based, three-part OpenID login system specification.
OpenID: the main page for OpenID is openid.net. For documentation about the Ruby gem for OpenID, see openidenabled.com/files/ruby-openid/docs/2.0.4/classes/OpenID/Consumer.html.
OpenID on Rails: the main Wiki page for this is wiki.rubyonrails.org/rails/pages/OpenID.
There are a number of blog postings and tutorials about OpenID and Rails, some of which are more out of date than others. Perhaps the best one is railscasts.com/episodes/68, which is a nice visual introduction (along with source code) about what is happening.

Until recently, IBM’s Power Platform was looked upon as being the system that hosted IBM’s flavor of UNIX and proprietary operating system called IBM i. These servers often are found in medium-size businesses running ERP, CRM and financials for on-premise customers. By enabling the Power platform to run the Linux OS, IBM now has positioned Power to be the platform of choice for those already running Linux that are facing scalability issues, especially customers looking at analytics, big data or cloud computing.
￼Running Linux on IBM’s Power hardware offers some obvious benefits, including improved processing speed and memory bandwidth, inherent security, and simpler deployment and management. But if you look beyond the impressive architecture, you’ll also find an open ecosystem that has given rise to a strong, innovative community, as well as an inventory of system and network management applications that really help leverage the benefits offered by running Linux on Power.Get the Guide
