I found http://groups.google.com/group/growing-object-oriented-software/browse_thread/thread/47695af2c6b5adda fascinating, so I decided to make it a little more concrete. It's also in ruby using rspec, sorry about that. Here's the code under test:

class EligibleForDiscountPolicy
  def initialize transaction, user
    @transaction = transaction
    @user = user
  end

  def decide
    return true if @user.is_gold_member?

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."

GitHub (Bash) Shell URLs

Local Shell setup

This is an environment file to source upon shell startup (via .bashrc/.bash_profile or your shell's corresponding file). If your shell isn't Bash you will likely need to port the functions to your shell's syntax.

Setup your local clone of a GitHub repo

When inside your local Git clone of a Github repo you need to do the following (only once per repo):

void add(int *a, int *b) {
    int i = blockIdx.x;
    if (i<N) {
        b[i] = 2*a[i];
    }
