Version 10 empowered!


(also known as Spartacus)


See those two pins? Well today I'm going to... stick them in you.


Ok, let me come clean: Mr.Wizard is actually an alias of mine... I'm glad I can finally confess. ― Sjoerd C. de Vries

No, I'm Spatac... I mean, Mr.Wizard! ― R.M

I'm Mr.W, and so's my wife! ― acl


@Spartacus, it was not fixable. ― rcollyer

check again; I just fixed it. :-p ― Spartacus

"My main purpose of being here is in collecting the votes. I'd even go further and say that this is my main purpose in life." ― Leonid Shifrin

Some people are fortunate. Others get married. ― belisarius


It's not that easy to do the untangling even manually though. – Szabolcs

Maybe you could turn it into a puzzle and let other people do the untangling :-) – Heike

I could make a web based game, and feed all my graphs to the visitors.
SE is a big game, isn't it? :D – Szabolcs

... but I am working with a large body of code written by an incompetent fool (i.e. myself, several years ago...) – Simon Woods


I was tempted to edit your title: "Do rules rule?" But my nose is still bleeding as a result of a limerick. – belisarius

comment Behavior of Commonest when there is an even split between the elements of the list it is given
In fact it seems that in version 10 it is always the last of the equally-common values that is returned. data = Permutations[Riffle[#, #] &@Range[5]]; Position[DeleteDuplicates@#, Commonest[#, 1][[1]]] & /@ data // Union yields {{{5}}}. I think that must be considered a bug. Will you post a Question highlighting this so that we may tag it as such?

@Liam I don't understand your comment. What do you mean? Were you not referring to \[Placeholder] as generated with Placeholder[]?

@belisarius While I am sure you are joking FYI (mostly for anyone reading): if you really must reverse a vote you can edit a post which unlocks the "already voted" thing.

@Jens You misunderstand me, and underestimate the respect that I have for you. I learn a lot from your answers, at least those that I have the knowledge to understand, and I seek to learn from you again in this case.

@eldo Votes for answers are not votes for the question. If they were the Reversal badge would not exist. Further I do not appreciate your analogy. I am not disrespecting anyone. You will note that the put on hold block states: "Please clarify your specific problem" and that is exactly what is (or was) needed. Do you agree with Jens' addendum? Does that match your expectation for this question? If so I shall reopen this.

@eldo I think not. Five people agree with Pickett's comment that this is unclear; only two people have voted for your question. The democratic vote is on the side of this needing additional clarity.

@Jens I suppose it may be another case of my ignorance showing but I am thinking of Array as a declarative construct, not an imperative one. My answer "feels" functional to me, but I may have a warped perspective. If your argument is that this must be done through recursion shouldn't you give an explicit implementation rather than (only) using a high-level construct such as CellularAutomaton, whatever paradigm it belongs to?

@Jens I don't have a CS background and my opinion has no authority but quickly refreshing my memory I feel that my answer fits the definition of functional programming. Would you at least explain to me why you believe it does not?

comment How to blend two photos in Mathematica?
@belisarius Thanks, but I prefer that people do not use votes in that manner. (Counter other votes, "retaliate," down-vote because a post is "too popular" etc.) IMO a vote should be determined by a post itself not the way others reacted to the post.

@Jens Then apparently I don't know what functional style is. Why don't you extend the Question by clearly specifying your interpretation of functional programming?

comment How to build a game board
@Jens Both our answers use an iterative function to generate an array. If you are implying that yours is functional and mine isn't I'd love to hear your argument.

@Jens What does that even mean? I'm closing this question pending clarification.

@MichaelE2 "Darn" too, because looking at the other question I suppose this one should be closed, and the Accepted answer there is essentially the same as my answer here, just a little less terse. :-/
