# Depth-first search (DFS) is an algorithm for traversing or
# searching a tree, tree structure, or graph. One starts at 
# the root (selecting some node as the root in the graph case)
# and explores as far as possible along each branch before backtracking.
#
# A graph can be represented by its adjacency matrix G,
# where G[i][j] == 1 if there is an edge between 
# vertices i and j and 0 otherwise.

My issues with Modules

In researching topics for RailsCasts I often read code in Rails and other gems. This is a great exercise to do. Not only will you pick up some coding tips, but it can help you better understand what makes code readable.

A common practice to organize code in gems is to divide it into modules. When this is done extensively I find it becomes very difficult to read. Before I explain further, a quick detour on instance_eval.

You can find instance_eval used in many DSLs: from routes to state machines. Here's an example from Thinking Sphinx.
