(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

comment Customizing display of partial differential equations
You're right; since TraditionalForm is not for editing anyway I guess my concern is baseless. I merely got in the habit of using MakeBoxes preferentially to Format most of the time. +1

comment Customizing display of partial differential equations
Be aware that MakeBoxes can have superior behavior to Format in some ways. See this Q&A: (4112299)

comment difficulty abstracting the OptionValue pattern
@Reb.Cabin Unfortunately that doesn't really tell us much since Normal works on a number of standard expressions as well. (e.g. GraphicsComplex.) Further, even if Association is atomic it could still behave more like a standard expression; SparseArray is also atomic yet you will find that the examples using Block and With do affect its contents.

Please try evaluating SetOptions[Integrate, GenerateConditions -> False] before running your code and see if it then behaves as you expect.

There appears to be an error in your definition for g: lamda2 instead of lambda2.

comment An efficient way to merge a pair of 4d arrays of non regular length lists
@murphc05 The single Table form does work, but the iterators are given outside-first: Table[{i, j}, {j, 3}, {i, j, 3}]
