comment What makes a language Turing-complete?
@dopatraman It's really just "a programming language able to do all calculable calculations". Just like maths it's not the answer which is important, but the proof. The recursive (indirect) way is used more since it is the easiest way to prove turing completeness.

comment If Scheme is untyped, how can it have numbers and lists?
Hope you are not meaning weak when you write loose. Scheme has strong typing.

comment What makes a language Turing-complete?
It has two formal definitions for Turing completeness page of Wikipedia. One requires I/O the other doesn't. The one that doesn't say that a machine is turing complete if it can calculate every Turing-computable function. That puts lambda calculus back to being turing complete since you can easily make a equalent program in lambda calculus that calculates the same as any turing machine programs.

comment What makes a language Turing-complete?
@Rhymoid So you mean nothing is turing complete unless you can make an interpreter? Ie. lambda calculus is not turing complete even if it's turing equalent?

comment How safe & trustworthy are hosting sites such as sourceforge, github or bitbucket for closed-source projects?
@StefanBilliet Probably none of us are capable of securing our source 100%, but with keeping your github enterprise instance at a local network crackers will need inside help to do the same they can do anytime against a public server.

comment random unique pair numbers from two range
@ArashMousavi Most of reset() is to mark all values where the value, after adding offsets, would be the same. Eg. if you have ranges 3-5 in both it will remove (3,3), (4,4), and (5,5) by marking them as used. I've added more comments.

@MichaelT Nice code. Perhaps GMP library's gmp_setbit and gmp_testbit can be used in place of vec.
