data = Re[Zeta[1/2 + I Range[0, 100, 0.01]]];
It is nice that Mathematica can plot data in both Cartesian and Polar coordinates.

Charades or charade ( or ) is a word guessing game. In the form most played today, it is an acting game in which one player acts out a word or phrase, often by miming similar-sounding words, and the other players guess the word or phrase. The idea is to use physical rather than verbal language to convey the meaning to another party.
In the United Kingdom, the game is traditionally played at Christmas and on New Year's Eve.
Brief background
It was originally also used to indicate a riddle either in verse or prose, of which the listener must guess the meaning, often given syllable by ...
I was looking for a picture of a man falling from a building for the silliest picture to go with the phrase "I'm Batman", but my sensibilities kicked in at the last minute. Eesh, I am sorry I thought about that.
Although this is probably dumping oil on dead still water, could we consider closing this very old question? The answer is almost certainly NO, but this is a typically unprovable negative. I suggest closing it as needed WRI's expertise to answer. Anybody agree?
Too long to post it here, but not difficult at all `ToExpression@ Uncompress@ "1:eJxTTMoPCnZjYGDwzC3ILyqJVsooKSmw0tdPTC9NLM7Py0zWS87P1S8v0E3OzytJz\ SvRLy3IyU9MKdY3MjA00jewBCs0NDIz1MsqSFeKBQARdRnL"`
@J.W.Perry My most often used palette is the SEUploader, then comes the colors, then the AttributeViewer. I almost never use the drawing tools and only sometimes the writing assistant.
@J.W.Perry Yes, quite often. I have a palette to open my most frequently used Notebooks that I use constantly. I use Szabolcs's Paste Tabular Data palette regularly. I use the Special Characters palette fairly often.
@halirutan Is AttributeViewer a custom or default palette?
Hmm: this says we have 1008 unanswered questions; this says we have 992 with no upvoted answers. I would have thought that the latter should exceed the former, but whatever - who's going to pick up one of them?
I have a problem with automatic GPU memory management when using CUDA. The situation is the following:
I create a simple CUDA function that operates on a 2D array (image), which does not take much memory space. This 2D array is passed as input then modified and output again. The function is load...
@Rojo For one thing every button on the palette is color-coded to match the title section of the Notebook it opens; this makes it faster for me to hit the right one.
Maybe something fun for Windows users: I downloaded 1500 desktop wallpapers that randomly change, but the UI doesn't let you see the filename of the one that is currently displaying, so here's the snippet to read it from the registry.
I wonder why this question was voluntarily removed :D mathematica.stackexchange.com/questions/32221/protected-error (Set::write Protected error, suggested old definition and that I didn't believe it was a fresh mathematica session, got reply "@ssch don't be an ass. I know mathematica.")
Mathematica, 123 characters
A very rudimentary implementation that doesn't use Mathematica's built-in CellularAutomaton function.
ListAnimate@NestList[ImageFilter[If[3<=Total@Flatten@#<=3+#[[2]][[2]],1,0]&,#,1]&,Image[Round/@RandomReal[1,{200,200}]],99]
@ssch That was my first attempt when the question was fresh. I ended up with a very convoluted code (I think I still have it somewhere) and finally decided to stop
@rm-rf huh, you would have thought I noticed that. I guess maybe I should be off the hook anyway. Maybe I should have alcohol in my system, it would give me an excuse. :)
Your task is to build a piece of code that generates an aperiodic sequence of integers, either by outputting one every time it iterates, or by taking an integer n and returning the nth number in that sequence.
Now, the sequence 1, 2, 3, 4, 5, 6, ... is itself aperiodic, so I'm going to introduce...
That is actually a difficult task. It reminds me of the task of trying to write a piece of true pure atonal music. As I recall it cannot be done for more than a measure or so in my father's description.
All my notebooks start out well organized, but then become a huge tangled web of unreadable mess... After 3 months, I don't know what needs to be initialized and what might override something else
I came back because I just saw youtube.com/watch?v=Oie1ZXWceqM#t=92 and it makes me wonder how lame we are with how difficult we find the object detection image processing questions. Eso es todo cuanto voy a decir
@Rojo Nothing's difficult given the time and know-how. The difference here is that the video is probably someone's PhD thesis work... not an SE question :)
@robjohn "potted plants" — it's ok, you can say the word in this room. No DEA agents lurking... :P
@Verbeia Curiously, I don't find the unanswered count going up as a negative measure. Perhaps some kind of deformed pseudo-scientific view of the world, but without unanswered questions a subject becomes dead
@belisarius Yes, but 10% is a bit much. I think some have just been swamped by being hard questions in a rising tide of questions. We get 30-40 every day now, which is way more than I can look at.
@belisarius I agree with that... I guess Verbeia's and partly mine and some others' concern is that some of those unanswered questions remain unanswered simply because the question is uninteresting/the answer is a one-liner/too simple, etc. In such cases, it should either be closed or answered, so that the "unanswered" list will actually reflect the unasnwerable questions.
@belisarius Yes, but what's in the "first few" depends on sorting order, and not everyone sorts by votes (some don't know that there's a tab for that). So it's quite likely that the boring ones are in front...
@rm-rf Well, I used GeoDistance to win an albatross, but I can't say that I use it on a regular basis. Feel free to send a specific example to support.
@belisarius Brookfield Zoo near Chicago has a nature exchange where kids can bring in things they find in nature to get points. The points can then be redeemed to get other items that have been brought in. My child was very upset before our last visit when I explained that every cool item that had been collected recently was on the "not allowed" list.
@BrettChampion I don't have premier support, so I almost never contact support because I'm not hopeful of a response... In any case, here's an example:
In contrast, MATLAB was about 1 second (or somewhere in that order), IIRC. I don't have a license checked out right now, so can't time it immediately.
I now use MATLAB for this part of the work, which is good... use the best parts of each, etc., but I'm surprised that this takes so long on Mathematica.
@JacobAkkerboom yes it is. I found yesterday couple of interesting question worth to focus on so I will answer them in the evenning I suppose :) If I manage to figure them out :)
@JacobAkkerboom but the event works :) 980 and decreasing :0
Try to hit 5,000 exactly, and take a picture. Or pick a humorous or interesting number:
Also, the real "celebration" starts at 10,000 -- celebration for the moderators that is, because you'll see all the deleted junk and (1) have sympathy for us (2) accept the mantle of responsibili...
@Kuba ahh, of course! I only saw it after John Fultz commented, but he must have seen it because of that then :). Well, in retrospect, that was a good unaccept (and maybe even downvote :P), as I needed to change that thingy about the front end not being used :)
@JacobAkkerboom don't waste time on chat, answers are not going to appear from the void ;) You should look at is:question answers:0 [notebooks] since you are quite experienced at this topic
@Kuba well said. Did you have a look at the fractal dimension question of @VitaliyKaurov mathematica.stackexchange.com/questions/13125/… I failed to answer this due to my short bursts...I guess its worthy of a good answer..
@PlatoManiac I like your avatar. This 'game' was one of the first things I've tried to implement in Mathematica but back then I was writing codes with Fors etc so I failed in terms of performance ;) And 2 years later I found this question here :)
@PlatoManiac well, it is unanswered for a reason :P I don't think I can handle it :) or any from the first page of unaswerd question sorted by votes ;)
It seems I have lost 5 reputation points on Stack Overflow yesterday. The reason given in my history is "removed". On mouse over I get the message "user was removed". I don't understand what that means. What caused this?

I know that even if you knew, or if he was hiding at your home, you would be under a NDA :P. Same happens if I ask you what are you developing for MMA 10
@Rojo Well, let me just say that it will be one of the central features, and long requested by many. This time it is not my solo project though, many other folks are involved.
Hi @Verbeia!
@Verbeia Nice party here!
@Rojo I just hope we manage to get this ready for V10. Tons of work still ahead of us.
Do spidering some of the crazy micro parties that got elected to our Senate this time, you'd think he would have done better in his bid to be elected to the Senate, not that he could actually attend Parliamentary sittings.
Obviously we can't discuss this, but if anyone is reading, some documentation of TemporalData and a fix for the EMF bar chart bug would both be very welcome.
@LeonidShifrin It's good, busy months. My work situation is a little bit messy, a couple of alternatives opened but I still lack information to decide what to do so.
