@alecco Thanks for stopping by, I really appreciate it :) Not many people would be nice enough to do that. If you ever do use Mathematica in the future, remember our site... new users are welcome here :)
I wonder how they track fingers without any sensors... for example, if you extended your palm out, facing upwards and folded your fingers, the palm should shadow the fingers, no?
@RM it seems like the two week avg of visitors/day is starting to see an uptick. I couldn't imagine that the 38k views of your question had anything to do with it.
@rcollyer Ha! @RM I showed that to my GF - she loved it. Usually, she won't hear me talk about this website or anything MMA related. But that, she found very cool.
@rcollyer I was in Utah last week... 2$/cone and yeah, about 8". A foot if you include the cone. Another place served 1/3 pound of icecream delicately balanced on a cone... Compared to those, I'd be lucky if I can get something the size of a baseball here
@belisarius A bit if a rant of my own: I fear that Mathematica is getting too big for its own good. Many things have been added, but it appears that existing functions and operations are getting slower in new versions. Further, there are many bugs and performance gaps that appear to be passed over in favor of adding shiny new features, sometimes with their own bugs and idiosyncrasies.
The language itself is very expressive and I wish I felt that more attention was given to making it as fast as possible, yet there are issues such as the lack of performance of the pattern matching engine I asked about on StackOverflow. I really wish that by this time, instead of "Compile to C" there was a JIT compiler of sorts that would optimizing the native language to the maximum degree.

I know this is not easy but neither were the great many features that have been added between versions 4 and 8.
@MrWizard I share your concerns, but otoh a new release is always something like Christmas. I spend weeks unwrapping all the presents in there. Having only bug fixes, however necessary, would be a big let-down.
Typing this on my iPhone in the waiting queue for the barber/ hairdresser or whatever the current term is in English nowadays.
@RM thanks for the link. I was a bit afraid to pre-order but this sounds genuine.
I just asked the guy next to me in line who happened to be from the UK. He confirms your claim. It's a bit old fashioned he says but getting fashionable again.
I have posted a new version of dynamicPartition. Since, unlike the last version, I have not actually used this regularly I would appreciate some help testing it to make sure it works correctly.
@belisarius Since when can one determine ethnicity from an IP address?
@Artes yes, I wanted to talk about the question I deleted. You flagged it saying it should not have been because the answers were not all duplicates. I'm here to listen.
@MrWizard Ok, I agree that post could be closed, but not sure if it's ok to be deleted.
@MrWizard There were e.g. yesterday another question closed as well, but not deleted. So I'm a bit confused on the policy of what questions are to be deleted.
@Artes It seemed to me that it was a clear duplicate, and the answers were duplicates. It also did not seem that it would significantly help someone find the answers through search. On this basis I deleted it, as it is part of my role to keep the site clean. I am of course interested in the community (your) opinion on such matters.
@Artes Okay. First, it has not been there very long and I prefer to let a quesiton sit for a while before deleting. Perhaps the community will vote to reopen for example. Second, the wording seemed enough different that it might be found in a search where the original is not, thereby helping someone find the answers.
With[{n = 4}, Nest[(# /. gc : GraphicsComplex[pts_, __] :> Map[Function[p, Translate[Scale[gc, 1/2], p/2]], pts]) &, PolyhedronData["Octahedron"], n]]. Change n if need be. You can replace "Octahedron" with "Tetrahedron" or "Icosahedron" if you are so inclined.
Nowadays, making Sierpinski versions of Platonic solids is so easy... I needed to write a good amount of code for those pictures back in the day.
@MrWizard I have a question on Mathematica blog. Could you point out some references for me to understand what it is intended for ? I am rarely on chat and I may not know some important issues.
@Artes Also, the deleted question described the problem in terms of graph edges just as the original did. The yet-undeleted duplicates describes it in terms of sets or lists. It may be best to include sets/lists in the original to take care of such questions.
@Heike, yes, I accumulate favourites and never remember to check them out
Also when you sort the questions by "Active", they all say "modified" it would be nice to see at a glance if a new answer was added, a comment, an edit or what
@Heike Nope. Just plain SurfaceColor[]. (I did that particular picture in version 4, you see.)
@Rojo Comments don't bump questions. You can add a comment to a very old question, and only the post owner and whoever you @-ddressed will know that you added a comment.
@MrWizard I think the problem is specially suited to that solution. Reciting the algorithm: "a number is happy if the squared sum of its digits is happy. 1 is happy. If while doing this loop you come into this number again, assume it's not happy. If it turned out it was happy, all of the numbers in your path were also happy, so remember to overwrite your assumptions"
@MrWizard, you temporarily use that same happy[num] place to cache your assumptions, should your recursion turn into a loop. If it doesn't, well, you'll overwrite your assumptions afterwards so it's fine :)
According to area51 we have 14.6 questions and 1494 visits per day at the moment. It would be nice to reach 15 questions and 1500 visits again before we graduate.
I'm still puzzling on how to make the inner surface more bread-like. The current coloring I have is a start, but still a lot of work needs to be done to make them look more plausible as holes...
@Rojo I have a few things I could submit (though they were originally intended for my blog :D ).
@Rojo Oleksandr got interested in a compact routine I wrote for generating Savitzky-Golay smoothing coefficients (it's in the transcript somewhere). I've been sitting on that algorithm for too long, and a new blog is as good a place as any to post a description of that routine...
@JM so I guess I have some weeks to learn what a Savitzky-Golay smoothing coefficient is, until @Heike, the visualization queen, posts some attractive appealing graphics, so that then you dare post your own
Humm, I think I should improve my English before deciding to contribute to the blog. That last sentence proves it
@J.M nice, but I needed a Sierpinski hamburger. I was thinking of deep-freezing one and than slicing it in a microtome while making pictures of the each slice to get a good 3D texture. Alas, I don't have access to stuff like that anymore.
@SjoerdCdeVries That's a harder proposition. To do something with the genuine feel of hamburger, we'd need bump mapping, which Mathematica doesn't support... yet.
@Heike Looked it up. Seems tasty. Maybe when I'm in Europe again...
@JM I see lots of them when behind a Iphone or iPad but answering Q's on that is just a pain or simply not possible. I feel my fingers itch, sometimes. Luckily, moderating is a different thing.
@SjoerdCdeVries At least you seem to be converse in chat on your iphone/ipad. I still haven't found a browser that lets me do that on my android phone.
@SjoerdCdeVries I can see the chat channel and the input field but when I try to type the keyboard refuses to stay on the screen. It pops up but then disappears again.
At my work we used to have HTC's, but they had lots of problems. They decided to switch everything to iPhones in September. The whole department was exuberant
BTW do you know whether we can have downloads in our blog? The one I'm considering would need a dxf file.
@SjoerdCdeVries The main problems I have with iphone/ipad is that everything is locked in and that the memory isn't upgradable. If that hadn't been the case I would have bought an iphone instead of the android I have now.
@SjoerdCdeVries I have 8GB in my android and I'm constantly running out of space, but that's probably because I have around 7 GB of music/podcasts/films on there.
@SjoerdCdeVries Maybe locked in isn't the right term. I like to use my phone as a portable hard drive. If I plug it in it shows up as a removable disk on my desktop. Maybe things have changed, but I couldn't do this with my ipod touch, which is why I switched to android.
@Heike If I attach it to my PC I can see the pictures in a windows file browser. I suppose (but haven't tried it) that I could put files on the device using the same.
