# In Chef, when a resource is defined all its variables are evaluated during
# compile time and the execution of the resource takes place in converge phase.
# So if the value of a particular attribute is changed in converge
# (and not in compile) the resource will be executed with the old value.

# Example problem:
# Let's consider this situation where there are two steps involved in a recipe
# Step 1 is a Ruby block that changes a node attribute. Rubyblocks get executed
# in converge phase
# Step 2 is a Chef resource that makes use of the node attribute that was

Intro

Being a cheapass student, I couldn't resist to try to win a free entrance to [Area41 Security Conference][3] (don't mix with Alcoholics Anonymous Area 41 in Nebraska) after spotting @gandro23 retweet about the conference and the challenge.

Level 01

The challenge starts after downloading and extracting a [binary][1]. A quick look
