Hello, I am converting to and from hex nibbles using the code below. Is
there a smarter way for this?

To hex nibbles:
'testing 123'.scan(/./).collect { |i| i.unpack('C')[0].to_s(16) }.join
=> "74657374696e6720313233"

and back to binary:

"74657374696e6720313233".scan(/../).collect { |i| i.to_i(16) }.pack('C*')
=> "testing 123"

Thanks,

/D
