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

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 Intersection of lists of disjoint intervals
@Mammouth I don't see any difference in performance, and I think there shouldn't be as they are essentially equivalent. By the way the parentheses are extraneous here.

@mfvonh I think if he had wanted to Answer he would have. It is good that you posted.

@Mammouth Welcome aboard. :-) Take a minute to view the Tour. If you have any questions about the site itself visit Meta.

comment Intersection of lists of disjoint intervals
Mammouth: that depends on what you mean. If you mean is it possible to Accept a comment as an answer, no. If you mean is it possible to "promote" a comment to an answer, no. However, you can always ask the author to post his comment as an answer, or you can even post it as an answer yourself, though it's polite to ask him first. In this case it seems that @alancalvitti preferred merely to comment, and mfvonh has already (re)posted his method as an answer which you have Accepted. Everything is as it should be. :-)

@Maya If you have the polynomial for n=7, n=8 please include them.

I replaced the LaTeX with Mathematica code; please confirm that I entered it correctly.

comment Controlling the placement of the y-axis
@eldo Frankly I didn't think of that. You'll need to pick between those two forms based on the data (to make it universal) but that should be a good solution. Why don't you post an answer?

comment Controlling the placement of the y-axis
@eldo Only for data of the form {y1, y2, y3, ...}. My method will also handle {{x1, y1}, {x2, y2}, ...}. I suppose I should include that point in the answer.

Okay. And I agree your plots look nicer. :-)

comment Controlling the placement of the y-axis
Well nuts. I didn't see this answer before posting. (Blind?) I just posted something very similar, though I think a bit cleaner. Would you like me to edit your answer to include (or replace with) that, or shall I leave my answer?
