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


"I am making some voodoo dance and invoking the rain God while we talk" ― belisarius


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


No, but they nowadays let me turn off the lights at night; 24 hours of fluorescence was really starting to make me feral. Brett says I should also mention the tip jar... – Daniel Lichtblau Mar 13 '12 at 20:48

Please give a more concrete example. Also are you using Wolfram Mathematica or should this be moved to another site?

comment Why Infinity /. _?(# < 6 &) -> 0 replaces Infinity with ComplexInfinity?
I agree with becko.

comment Why Infinity /. _?(# < 6 &) -> 0 replaces Infinity with ComplexInfinity?
Great summary answer. I regularly recommend FullForm for understanding pattern matching you went well beyond that. FWIW I think my heldCases is useful for debugging patterns as the matched items are not inadvertently evaluated. If you agree would you mind including mention of it?

comment PlotLegends won't generate automatically more than 15 labels in v10
@Bob A shorter way to write that: Length /@ ColorData["Indexed", "ColorList"] // Tally

comment PlotLegends won't generate automatically more than 15 labels in v10
@SquareOne "Expressions" is not a color scheme. The default colors for Plot in v10 are given by ColorData[97, "ColorList"] (length 15).

comment How does Mathematica interpolates?
While this question is not a duplicate I believe "(it) already has an answer here" does apply so I am joining belisarius in voting to close. If anyone feels this question is not adequately addressed there please let me know.

comment How to do algebra on summations of variable expressions?
Thanks, Simon. It would be nice to see this kind of functionality well integrated into Mathematica before Facebook etc., IMHO.

I think Expand might be more appropriate than Simplify here. +1 of course.

I don't believe you need the , 1 here. Or am I forgetting something?

@Simon Thanks for the bounty for my question! I would like to return the favor. What questions on this site would you like to see get more attention?

Beat me to it. +1 Now are you going to fix it? :^)

comment Plotting jump function without vertical lines
@yadaddy FYI: I modified myPlot to use only a single Line expression; this speeds rendering in the Front End.

@Marius I don't know without testing. On the surface I wouldn't expect any large performance difference but I have been surprised before.

comment Linear function on strings using UpValues
@Marius Glad I could help. Another formulation you might consider is: Sup[i_Integer] := i; Sup[x : _[__]] := Sup /@ x. This maps Sup over any compound expression. Atoms such as Strings or Integers are then individually handled.

comment Changing the atom color for plotting xyz-files
Great find! For the particular problem I can't imagine a better answer. I still do like the generality of my approach and I hope people find value in it elsewhere.

comment Plotting jump function without vertical lines
@yadaddy You can only Accept one answer but as you have discovered you can always change it. Also you should not feel pressured to Accept any particular answer; it's a personal choice. However when I lose an Accept I often wonder if I could have provided a better answer, which is why I asked.

comment Plotting jump function without vertical lines
@yadaddy I am curious why you switched the Accept to this answer. Is it not similar to my myPlot approach? However using Plot is not as efficient as drawing Lines directly. If there is a problem with my code please let me know and I shall try to correct it.
