alt Hacker NewsDo you have a mathematical formulation, or?
Ultimately you seem to pick a random definition of computing and size and then work with that?

The article described why the choices were neither random nor particularly arbitrary.
"Computable" has a well-known standard definition in this context, meaning a computable function[1]. In a given model of computation, a computable function is one for which an algorithm exists which computes the value of the function for every value of its argument. For example, the successor function adds 1 to an input number, and is computable. The halting problem (determine whether a program given in the argument halts) is not computable.
