Ruby translation of the original Python gist. There is also a Scala gist translation.

Thanks to MrZYX, Hanmac, and jacobian for the pack and unpack solutions!

For converting to/from hex strings, you can also do: ["3435"].pack("H*") and "45".unpack("H*")[0].

@jacobian Awesome, thanks!! Swapped to your solution above. (Made the column way smaller, yay!)
