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

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

@Voo Wouldn't you check your results anyway for important computations? Heat may degrade components but not necessarily faster than other system components already degrade. Anecdotally I have not yet had a CPU die and I tend to keep mine for a long time.

comment Plot of Implicit Equations
Incidentally I get a fairly similar result much faster with: ContourPlot[E^(Sin[x] + Cos[y]) == Sin[E^(x + y)], {x, -10, 10}, {y, -10, 10}, Axes -> True, ImageSize -> Large, MaxRecursion -> 0, PlotPoints -> 1000]

+1 for the computational expense to demonstrate a result

This is mentioned in Rojo's comment and the comment below it explains why the original author found it unacceptable. Nevertheless welcome to Mathematica Stack Exchange.

@bobthechemist As a point halirutan's 2700K was released Q4 2011 and retailed for \$332 whereas my 2500K was released in Q1 2011 for \$216. At the same clock my CPU gets about 2.06 where his gets 2.33 in the benchmark. I assert that one would get a faster reward by putting extra money into a better cooler for the cheaper chip and pushing it further.

@bobthechemist I don't have the "biggest CPU on the block" and that was actually my point: I would prioritize raw clock speed over newer architecture. For a while CPU's were actually getting slower from a clock perspective. Although Intel started locking their CPU multipliers on non-K chips, forcing me to get a more expensive CPU that I wanted to, I used to get good results by overclocking a budget CPU.

@Yves I didn't know that. That is disappointing. Have there been any efforts to unlock these cards that you are aware of?

comment Power[__] Pattern works like Level
@Algohi We all get surprises from Mathematica. It's just a matter of having a good set of diagnostic methods to determine the reason for the behavior.

That's more like it. That CPU is the big brother to mine so it should be faster. I think you'll find 4.6GHz quite stable; I use an offset voltage of +0.1v by the way.

You have an unlocked K series CPU -- why don't you run a higher multiplier?

comment How to execute code on FrontEnd quit?
Theoretically this should be possible by setting the $FrontEnd Option FrontEndEventActions but I don't know the proper Event name for FrontEnd termination.

@kguler that appears to hang in a Notebook as well.

comment Select a particular rules out of a list
Warning: KeyTake will by nature return only one rule for each key: KeyTake[{a -> b, b -> c, c -> d, b -> 2}, b] yields <|b -> 2|>.

Nice use of KeyTake. That one isn't in my repertoire yet.
