What is the best Ruby pattern to use in this Rails situation?
The interaction of the site is based on the input of user. For example, if the user selected "VISA" as payment method, he will be redirected to another controller/actions asking for credit card number.

How Does Ruby handle bytes/binary?
I'm trying to send a series of binary bytes across a socket, to meet a particular standard my company uses. No one in my company has used Ruby for this before, but in other languages, they send the data across one byte at a time, (usually with some sort of "pack" method).

Is there a consensus about test frameworks for Ruby 1.9.x?
A two-parter with a quick intro. Intro: I'm coming to Ruby from Perl, and I'm a bit lost among the test framework choices. I understand that there is probably no single, all-around best choice, but I can't even get a clear picture of the playing field. So, first, MiniTest or Test::Unit? I just realized that 1.9.1 defaults to MiniTest no...

Rails ActiveRecord BigNum to JSON
Hi, I am serializing an ActiveRecord model in rails 2.3.2 to_json and have noticed that BigNum values are serialized to JSON without quotes, however, javascript uses 64 bits to represent large numbers and only ~52(?) of those bits are available for the integer part, the rest are for the exponent.
