You can Rails 3 on App Engine, but it won’t be especially useful until bundler 10. You should try these instead:

• Rails 2.3.5: DataMapper version: gist.github.com/268192

• Rails 2.3.5: TinyDS version: gist.github.com/269075

Install the Development Environment¶ ↑

The gems for the development environment include a pre-release appengine-tools gem that provides a pre-release version of jruby-rack.

The Elements of Programming Style

The following rules of programming style are excerpted from the book "The Elements of Programming Style" by Kernighan and Plauger, published by McGraw Hill. Here is quote from the book: "To paraphrase an observation in The Elements of Style by Strunk and White, the rules of programming style, like those of English, are sometimes broken, even by the best writers. When a rule is broken, however, you will usually find in the program some compensating merit, attained at the cost of the violation. Unless you are certain of doing as well, you will probably do best to follow the rules."

# Project: Create a Proxy Class
#
# In this assignment, create a proxy class (one is started for you
# below).  You should be able to initialize the proxy object with any
# object.  Any messages sent to the proxy object should be forwarded
# to the target object.  As each message is sent, the proxy should
# record the name of the method sent.
