Subject: Re: How to take information from a text file and add them to an array

And as always with Ruby, there's an even simpler way to write it:

users_passwords = Hash[ File.foreach('input.txt').map { |line| 
line.chomp.split("\t") } ]
p users_passwords

I think that foreach would handle large files better than read or 
readlines too.
