@Murta @Mr.Wizard The question remains: How efficient is it to use replace with an association. I mean, it's a hashed structure and when you replace something, it has to look at all values just like in a normal list. I would be very cautious before I'd use this.
@Sjoerd, yeah, there are a lot of places here that can receive from Western Union. Even the pawnshop holding my computer has that capability. :D
"I think it's safe to say that I have some experience with using ParametricPlot3D[]" I asked if you tested the code on non-cloud.. From the fact you didn't answer, I'll assume No. — ChrisJJ5 hours ago
Can somebody with version 10.2 (to be sure) be kind enough to show the poor guy that his claim of Cloud specificity is off-base?
@Guesswhoitis. It is exactly the same on my Mac as the OP shows on the Cloud. The OP obviously has no evidence that the problem is limited to the Cloud. I considered responding in a comment, but things seems to be getting hot and I didn't want to fan the flames.
Here is a funny thing. IntegerDigits of a negative number should give all digits with negative signs. Instead it gives them with positive sign. Any idea why?
@Guesswhoitis. I would ignore him about this, if I were you. (In fact, that is exactly what I decided to do myself.) He seems to have some sort of axe to grind, unjustifiably so in my opinion.
@Guesswhoitis. Same behavior (M, not OP) in V9 & V10. I had upvoted your comment. I'm thinking of suggesting the OP try out the Wolfram community site. No closure, no rep, etc. The OP might find it more comfortable.
I might start ignoring the poor guy if need be, but I do have the responsibility as a bearer of the diamond; I don't like using my powers, but I certainly will if pressed.
@Oleksandr, I guess the obvious workaround is to isolate the sign (bit) first before anything else…
well, I did spike his guns a couple more times in meta. But, I did try to establish how he was perceived, why we reacted as we did, and to give us the benefit of the doubt.
and, hopefully, he'll take my advice and approach people here, first. Instant feed back is useful.
@Guesswhoitis. it is not quite so straightforward. What is the Hamming distance of -7 and 8, for instance? They are one's complement of each other. If you calculate it one way, you get 0. That is surely wrong. On the other hand, to calculate it a different way, the answer is 62. Also wrong. It seems risky to compare positive with negative numbers in this way. Or at least the answer is not well defined without some further assumptions.
@Oleksandr, on second thought, Mathematica treats negatives as having a (infinite) two's complement representation; unless I'm missing something, that makes them outside the domain of the Hamming weight function, per se.

@rcollyer he's tilting at windmills. He should find something more productive to do with his life, that people might actually respect him for. Like shouting at small children to keep off the grass.
I hate to say something ugly, but it makes no sense. The sun must be going down. I take it that the link is a shortened one.
In Plato's Republic there's a wonderful scene where Socrates warns not to teach people to argue logically at too young an age. They just end up yapping like puppies.
I suspect that the use of an archival link is his way of making sure we don't "erase evidence" or something. This is behavior I've seen before when I was modding other fora.
@rcollyer, make sure you expose the kids to the ones that feature a lot of classics, e.g. Rabbit of Seville. It's a sneaky way of making them like classical music. ;)
@rcollyer I wonder what is the difference, in his mind, between diagnosing the problem and answering the question of why the behavior occurs? It seems to me that his entire argument is full of sound and fury, signifying nothing.
@MichaelE2 tried to run it. had issues. fixed issues. moved on. :)
@OleksandrR. I suspect, he is of the opinion that his responsibility ends with the statement that he has a problem, not that he is a part of the process.
@rcollyer It seems that if I add color in V9 (PlotStyle -> {Yellow, Specularity[0]}), I still get all three plots the same...Sorry, it took me a while to understand. You mean they're riffled: Cases[p2, Lighting | GraphicsComplex, Infinity, Heads -> True]?
@Oleksandr, I know that this was a very long time ago, but do you remember us discussing Savitzky-Golay? If so, have you seen the routine I had posted in main?
@halirutan I don't believe I understand your concern. It's only replacing values so what does hashing have to do with it? As you said it's just like a normal list, and we regularly use replacements on those. Huh?
@Guesswhoitis. Unfortunately that behavior is sometimes needed. I'd like to think we are above that here but I am not offended by being held accountable, if that's how a user sees it. Kinda funny that I identify with this fellow today; maybe its just a mood I'm in. I really hope he doesn't turn out to be a troll, but somehow I get the feeling there's more to him than that.
Opacity of the first needle affects opaticty of scalerangestyle. It won't when I switch Blue and _Directive places. I also know I can put Directive[Opacity@1] on every other style directive, just to be sure, but it's not convenient in complex cases.
I would call it a bug, or at least poor design, someone forgot to put each element in separate brackets in Graphics.
Is it a bug that I cannot ask CurrentValue[$FrontEnd, MessageOptions] but have to use Options[$FrontEnd, MessageOptions] ? If I recall correctly last year John Fultz said something about not using SetOptions on $FrontEnd but CurrentValue.
@rcollyer When are we getting WolframPlayer 10.2 ? Now I have to workaround the ugly fact that due to the absolutely nonsensical default option of "InsufficientVersionWarning" in MessageOptions (in PlayerPro at least) you always get a warning when opening 10.2 generaded CDF's . Sometimes I wonder if Wolfram people do actually use their own products.
@RolfMertig They were in testing only recently, and I'm not privy to release info. Yes, we use our own products daily, some products more than others (I live in WB and the FE), but we do eat our own dog food. An unfortunate side-effect of developing these products is we often are using the development versions, and we can sometimes miss annoying configuration issues. I'll pass this issue along, so that the release mngrs are aware of it.
@Kuba a workaround is to set ScaleRangeStyle -> {Directive[Orange, Opacity[1]}. Not ideal, but workable.
@Guesswhoitis. when teaching the intro to physics lab, I gave my students the seemingly easy task of summarizing the day's experiment in two 5 sentence paragraphs: 1. the experiment itself, and 2. the results. Few, if any, realized how nasty of an assignment it was.
Ah, I think Feynman described a situation like that in one of his books. The students could parrot the statements from the textbooks, but were stumped when confronted with the actual situation where it's happening.
Hell, I haven't ever used a version 9 function ever since I came back, but managed to answer a few questions related to 'em anyway… :D (e.g. integer sequences and AnglePath[])
@Kuba But this is the same as CurrentValue[EvaluationNotebook[], MessageOptions]. The so-called documentation of CurrentValue claims that $FrontEnd is a typical object that can be used ... Uh well ...
@rcollyer @rcollyer Yes, that's what I mean. Outside perspective missing. So, ... do you have a WB 3.x (plugin) which actually works for generating documenatation when used with 10.2 ? Some days ago I tried to update the docs of my Shorcuts` package and failed.

@chuy I think the difference is that most users are interested mainly or solely in asking or answering good and relevant questions, not complaining about every aspect of the way the site is designed and organized.
"Wouldn't it be nice" if users would spend their lives doing something productive, instead of tiresome agitation? If these things really bother him as much as the flood of questions suggest, it will only result in raising his blood pressure and harming his health.
@Guesswhoitis. yes, I did see it (this morning, after you mentioned it last night). Thanks and have an upvote. For me the main trouble is dealing with the endpoints in case of the derivatives. But I haven't thought about it since we last spoke as I haven't needed to numerically differentiate anything.

There is also an element of selfishness in this; "The fact the user is using only WPC and is asking only for WPC is relation enough to WPC. If you want to ask the same question for all platforms, then post it yourself rather than interfering with the existing question." I mean, we're spending our damn free time on you, how about being generous on your end?
