This gist show problem with Ruby 1.9.3 on my Mac OS X Lion (10.7.2).

I've tried RVM and Rbenv+ruby-build. I tried linking with system openssl, rvm-openssl and homebrew-openssl. Even if linking succeeded, the error when requiring digest/sha1 appeared.

Problem with requiring digest/sha1 causes bundler not working at all.

This gist contains:

• test_1.9.2.txt - shows success on 1.9.2
• test_1.9.3.txt - shows failure on 1.9.3

MVC is not enough for backend apps. It's time for car (t)rap!

• C as Context (former controllers). Assigns roles to actors, runs the play.

• A as Actor - user, system, external system

• R as Role - DCI role injected to Actor by Context. User: [buyer, inviter], system: [shop, blog]

• T as Template - html, json, xml, whatever. It's optional, sometimes Presenter does the job

• R as Router - we need something parsing requests and passing them to proper context

• A as Artifact - product of actor's action. Order, invoice, product, post, profile. Persistence goes here

• P as Presenter (former helpers)
