#script tags are blocking operations, it cant do anything until it gets the script back; 
#Remember it has to request all of the script links individually from the server; 

#On heroku it will only include one script file and one css file which will be much faster as doesnt have to make lots of request to the server; 

#It is hard to debug stuff on heroku; 
#You can ask rails to run the production environment locally; 

rails server -e production #If you are having a problem that only appears in production, you can make the production environment run locally;

Crypto Square

One classic method for composing secret messages is called a square code.

The spaces and punctuation are removed from the English text and the characters are written into a square (or rectangle) and the entire message is downcased. For example, the sentence "If man was meant to stay on the ground god would have given us roots" is 54 characters long, so it is written into a rectangle with 7 rows and 8 columns.

Robot Name

When robots come off the factory floor, they have no name.

The first time you boot them up, a random name is generated, such as RX837 or BC811.

In other words, if I say:

puts "Robot 1: "

# Hexadecimal

On the web we use hexadecimal to represent colors, i.e. green: 008000, teal: 008080, navy: 000080).

Write a program that will convert a hexadecimal number, represented as a string (i.e. "10af8c"), to it's decimal equivalent using first principles (i.e. no, you may not use built-in ruby libraries or gems to accomplish the conversion).

The program should consider strings specifying an invalid hexadecimal as the value 0.
