Ah, interesting! I figured there would be a way without having to "brute-force" the solution by using the `permutation` predicate but I wasn't able to come up with one. I wonder if there's a way of not depending on permutation generation, nor list length. Does querying with `order(L)` require `length(L, 9)` to work?

As for the topological sort solution, I assume it's what Graphviz uses under the hood in mLuby's solution! If I understand correctly, we're graphing the sequence of reindeer and then extracting the order of the nodes in the graph?

No, `order/1` generates "too-short" solutions otherwise. If you redefine `order/1` to be a little smarter, like so:

    order([]) :- \+ follows(_, _).
    order([X]) :- \+ follows(_, X).
    order([X,Y|L]) :-
        follows(Y, X), order([Y|L]).

Then this works without knowing the length a priori, but it's less efficient:

    ?- order(L), forall((is_behind(X, _); is_behind(_, X)), member(X, L)).
    L = [prancer, cupid, rudolph, dasher, blitzen, vixen, comet, donder, dancer] .

Instead I'd discover the set of names (and therefore list length) using `setof/3`; this is similarly efficient to my original solution:

    ?- setof(X, Y^(is_behind(X, Y); is_behind(Y, X)), M), length(M, N), length(L, N), order(L).
    M = [blitzen, comet, cupid, dancer, dasher, donder, prancer, rudolph, vixen],
    N = 9,
    L = [prancer, cupid, rudolph, dasher, blitzen, vixen, comet, donder, dancer] .

That's super interesting!

I like how straightforward the solution is. The problem almost fades away! :)

That's because fundamentally it's a topological sort problem, and it seems like graphviz sorts the nodes appropriately before drawing the digraph.

Maybe there's potential to port the app to other platforms!

Yep, going to do all online pricing.

This general concept of going back to the source of the information can be applied to many other social networks to find higher-quality/interesting content. I started browsing hackernews because I realized a lot of the content posted on reddit on /r/programming and tech-related subreddits was often posted here first.

It all starts by taking the time to examine the content you consume & why you enjoy consuming it.

It doesn't show the code's comments though.

pocket's reader mode does though. (and the rest of the text looks pretty much identical to firefox's reader mode)
