@Guesswhoitis. I was informed after the fact, and it was a desperate scramble to delete them. :/

Hey guys, is there a way to do a continuous labeling of all columns in a chart? For instance, BarChart[{{1, 2, 3}, {4, 5}}, ChartLabels -> {{"r1", "r2"}, {"c1", "c2", "c3","c4","c5"}}] grouping the lists sepparately in r1 and r2, but doing a continuous labeling throughout the whole chart?

How do we deal with people who don't seem to understand how to program at all? The comments on mathematica.stackexchange.com/questions/89419/…

@PatrickStevens That user's English is weak, too, which makes communication difficult. See the related Q mathematica.stackexchange.com/questions/89438/…. (It's a continuation of the same problem, it seems. Can you see the deleted answer by the OP? It's got a semi-helpful image of what she/he wants. I can add it to the Q if you can't see it.)

I can't see it, I'm afraid.

@MichaelE2 I think that OP can just post in German if it suits them better. But the big problem, as I see it, is going from some arbitrary graph to wanting a plot of a probability distribution. All the context is missing, which presents more difficulties than a few slightly clumsy phrases.

@OleksandrR. I agree, but maybe the OP would be able to provide the context in German more easily than in English. Difficulty with English may be an obstacle to a clear question in this case.

@PatrickStevens I added it. It's also here: mathematica.stackexchange.com/questions/89514/… -- I didn't realize the OP has asked three times.

@MichaelE2 en.wikipedia.org/wiki/ABC_analysis seems relevant. I never heard of this before though

@OleksandrR. Yes, I saw that. I think that's what he wants and I gave such a solution in a comment to one of the Qs after it was closed. The OP didn't reply, though. (I hadn't heard of it before, either.)

Long as somebody's willing to edit his post with an English translation, I'm fine with him posting in German.

(Mine has gone stale from long disuse, unfortunately.)

I held off accepting Oleksandr's answer, just in case somebody came forth with something faster than the Hamming weight. Oh well… here's hoping WRI noticed it.

@Guesswhoitis. Dan certainly did. Don't worry about the accept although I do think you managed to squeeze more or less every last drop of performance out of it!

Yeah, I did see Daniel's answer. I hope he passed it along… :)

It was fun, but we shouldn't have to do things like this…

Hi, @Rojo!

@Guesswhoitis. I think his approach was motivated by not realising that the compiler builtins don't depend on the POPCNT instruction. So I added a comment to that effect. Quite possibly a LUT is exactly what they do use if the POPCNT instruction is not present.

Hmm, main site's down…

Oh no... baba ji is back as well: mathematica.stackexchange.com/questions/89685/…

@Guesswhoitis. I have had a lot of timeouts over the last few days using all SE sites. Hopefully this process will improve that, whatever they are doing.

@Guesswhoitis. It's coming back up....

Yep, just saw it. Prolly the CDN being slow…

@Guesswhoitis. they said that this process could take up to 6 hours, but apparently not

Maybe not six hours straight, tho.

*facepalm*

@Guesswhoitis. what a time-waster. He replied to my comment (not directed at him) here, but I thought it wasn't worth responding. The only thing I can see that he's made a good-faith effort towards is being a whiner. It looks like most people are ignoring him now, though.

Well, the lot of us are more focused on helping each other out than babysitting, I'd say. :)

As I told him, that guy has a weird way of treating people he says he has faith in…

He is like a broken record. The fact that nobody ever brought up these issues before would suggest that literally no-one else cares. And no matter how much he would object that they are serious issues, we have still built a successful, friendly, and productive community here long before he came along. And we'll still have it after he leaves. (The sooner the better, at this rate.)

Also, he seems to have misunderstood the fundamental basis of SE sites, namely that they are communities and driven by consensus. It is ridiculous for him to show up and, having received what seemed to me a quite normal response to his faulty questions, then demand that the site be redefined so as to result in him having been correct all along. It is narcissism taken to the point of absurdity.

"narcissism taken to the point of absurdity" - I think you hit the nail on the head there…

I mean, he had been called out that his interpretation of the point of asking here was self-serving, but he does not see it that way. He is just seeking "answers", after all. Ayyy…

Something that has been bothering me more is that the site seems a bit downvote-happy lately. For example, this question is a bit baffling (as to how someone could get into that situation), but I think it didn't deserve 3 downvotes.

I presume you migrated this question about Google Docs? An oddity that the user would choose to post this on our site, I think. Even more odd perhaps that someone would eat 70g (!) of sugar in a day and not realise that this is a carbohydrate

/shrug

What a time waster indeed.

@TheToad great response. I wasn't sure what he was referring to with this new question

@Oleksandr, yeah I migrated it. I'm half-seriously considering petitioning to have the word "Wolfram" added somewhere in the site masthead…

The guy with the nested lists was seriously confused, but honest confusion is certainly no reason for downvotes…

@Guesswhoitis. it would not be a bad idea, but I can't remember whether we avoided that in the past because WRI did not want it

@OleksandrR. I agree entirely. But, something about his responses made me think he might be somewhere on the autism spectrum. I had a student who was, and who greatly annoyed me.

That doesn't mean we need to continue trying, though. o_O

@rcollyer, I thought the same.
