@belisarius Actually, can't remember Ive done this before. But I think I see where you're heading at.

@SjoerdCdeVries I am sure it is nothing new to you. I used the concepts in this code yesterday:

A: Recursive function on list

belisariusIf you don't have to program for very long schedules and need the smoothest production schedule, you can minimize the variance of the daily production. I'll show you a way to solve the problem without specifying the list length a priori. This "method" can be used also when there are an unspecifi...

I was browsing Mathematica user communities for original projects and came by the following question: “How can I calculate a jigsaw puzzle cut path?” Such creative problems are in abundance at our user forums, the Wolfram Demonstrations Project, and The Mathematica Journal, which tells me that Mathematica, at its heart, is a conduit for creativity: [...]

@RM Yep. But I think the answer was half baked when the Q was posted
 
R.M
@belisarius the damn thing wouldn't fit in a toaster, that's why!
 
@RM Then do it with a lifesaver for siamese twins
 
R.M
siamese bagels... mmmm
Oh my... that question is taking off like crazy... the views jumped by a 1000 in 20 minutes
It was 1700ish when I got a badge and now it's close to 3k
 
@RM Yep. happened to me with the shadow removal thing the other day
@RM But I am not able to understand how reddit works. For example:
 
R.M
5:05 PM
@belisarius they implement silent banning at random, and increase frequency if you post a lot of links from the same domain
it's a catch 22... if you post a lot, they do this, but if you try to circumvent with a new account each time, then the silent banning is even worse because you're spankin' new
 
@RM Sounds too difficult to manage
Perhaps not for Yossarian
 
R.M
@belisarius yeah, it's not simple. Besides, @Sjoerd kept using the word "Mathematica" in all his post titles, so to a "serious" redditor, it looks like spamming
 
@RM It's just addiction
 
R.M
Thanks for the publicity, @VitaliyKaurov!
This is probably the first targeted exposure that we've gotten
 
@RM Hush! He comes here with the bill in his hands
 
R.M
@belisarius and 1000 pages of NDA for us to sign?
 
Hello
 
R.M
btw @VitaliyKaurov, if you use the custom link for the question (which embeds your ID), you'll probably get a gold badge for publicizing it :)
 
@RM Don't be fouled by the doc. It's the NKS in disguise
 
R.M
not that it matters much or you really care, but hey, why not
 
5:12 PM
@RM yes I was thinking it is great to give more light to the community
@RM I am not sure what that means ;-) "custom link for the question (which embeds your ID)"
 
@RM 18 points for that nonsense??
 
R.M
@VitaliyKaurov if you click on "link" under the jigsaw question, it'll give you a short url with your ID
 
@VitaliyKaurov below each question/answer is a link, labelled "link" conveniently, that embeds your user id in it.
 
@VitaliyKaurov Bravo! We may retribute by having a section on our wanna be blog indexing WR entries
 
@VitaliyKaurov You can use this link: mathematica.stackexchange.com/q/6706/13 Note the 13 at the end: it's your user ID. It will let StackExchange know that you're the one who shared the question.
 
5:16 PM
Oh I see guys thanks for clarification
 
R.M
If you don't feel like using that, use this link: mathematica.stackexchange.com/q/6706/5 :P
 
@RM Flagged
 
But where do you suggest I use that link?
 
In the blog post.
 
IN the body of the blog?
 
R.M
5:17 PM
@VitaliyKaurov in the blog post
 
Yes I got it now - thank you
 
@VitaliyKaurov Yes, in place of the current link.
 
@RM Maybe I should reply to that post.
 
Now we should post Vitaliy's article on reddit. Full profit :D
@Heike You both are toasted. Someone discovered you are rep gang
 
5:20 PM
@Vitaliy When the question was posted, I started to implement a puzzle game with mouse-draggable pieces, but then hit a performance problem, put the problem aside, and have forgotten about it. Maybe I should finish that
 
@belisarius Then where is my rep on Reddit (or karma or whatever it's called over there)?
@Szabolcs I actually did the same.
 
@Heike Sorry, I don't understand reddit at all :D
 
@Heike The problem I hit was related to bringing the piece I click to the front. Without that I could make it very fluid.
 
@Szabolcs Oh yes, I remember you asking about that on chat.
 
R.M
@Heike I just did
 
5:23 PM
@RM thanks.
@belisarius Me neither, which is probably why @RM gets all the points.
 
This one should be closed

Q: Comparison of Contour Plots between Various Programs

nkormanikI've constructed a number of smoothed, interpolated contour plots in SAS. The contours do not pass through the actual fairly 'noisy' data points, but are purposely adjusted so as to produce clean readily understandable contours. I'd like to compare the SAS contour plots with what Mathematica pr...

 
R.M
already has my vote on it
 
@belisarius I agree.
 
Sorry fell out foe a min.. Yes @Szabolcs that would be cool to see
 
R.M
5:41 PM
@Heike Could you also add the animation of the torus being pried open that you posted yesterday?
 
6:06 PM
Wow, 6500 views and the counter is still climbing. @Heike, it's indeed the right time to improve the answer!
 
R.M
@Szabolcs that's why I suggested it...
 
@RM I know, but you didn't mention the 6500 :-)
 
R.M
btw, was my answer on ButtonNotebook/EvaluationNotebook what you wanted?
 
@RM Not exactly, see my comment there. Based on what I read in the docs, I had the impression that there may be a situation where they return different things when evaluated in the same contexts.
already 7200 views ...
that's the same as the usual daily total page view count
 
 
1 hour later…
7:21 PM
@Szabolcs I'm typing this on my phone. I'm away from my computer right now and I won't be able to edit my post until after midnight. Maybe someone could do it for me? The .GIF I posted in chat yesterday should work.
 
@Heike done!
 
7:36 PM
Hi folks
 
@SjoerdCdeVries Hi Sjoerd. Quite a stir on reddit, as I'm sure you noticed
 
Well, I just got in and read it here in chat
@szabolcs I'm actually not that familiar with reddit. I have been reading the frontpage for a couple of years using an iPhone app, but that's about it. Thought it would be good to make the programming community over there aware of the Mathematica site over here.
just like I did with twitter and the Mathematica Linked-in group.
Anyway, it also helps to make the point that the publicist badge is way too easy. It takes less than five minutes to get one, whereas gold badges are supposed to take blood, sweat and tears. I'm at 35% (175 posts edited) for the copy editor badge which means that It'll take me another year to get it. Perhaps I should post about it on Meta.
 
7:52 PM
@SjoerdCdeVries It's to motivate people to share. For my gold badge I want an [badge:epic]! ;D
@SjoerdCdeVries Don't worry about it, we got weird reactions even on A51, remember?
 
@Szabolcs Yeah, conspiracy theorists everywhere
 
@Szabolcs Reversal is quite good
 
and this reddit post is visibly drawing in people right now, both new users and new answers (possibly).
 
ummm, reversal?
 
Sorry, Andreas Lauschke was probably not drawn by that. lauschkeconsulting.com
I knew the name was familiar.
 
@belisarius Yep, that's a special one :-)
Got to sleep now, need to be up early tomorrow, 10 year school reunion :-)
no internet for 2 days
 
@Szabolcs The problem with reversal is that the questions almost always get deleted afterwards
 
@szabolcs there goes your fanatic streak again

Q: The Lost Worlds of the Reversal Badge

belisariusI love the gold Reversal Badge An outstanding answer to a bad question is something not seen on a daily basis. I enjoyed reading those answers, and I was even able to provide one. But the questions are awful, and SO is a Q&A site ... so they are getting deleted. Sixty-four ba...

 
8:18 PM
@R.M I see I got you a "famous question" badge...
13k views now
 
R.M
8:51 PM
Thanks @SjoerdCdeVries :P
@belisarius You can get the link to the question by clicking on the badge...
 
@RM 14k now. I'm reading the reddit thread now. What a heap of paranoia over there. Not sure whether I should react. Anything that you say can and will be used against you.
 
R.M
@SjoerdCdeVries It's pointless... just leave them be.
 
@RM I haven't had time to check this evening's questions.
BRB
 
@Mr.Wizard So, how does ListCorrelate (or ListConvolve) work? I'm curious.
 
R.M
@SjoerdCdeVries Publicist is actually not all that easy... In nearly 4 years of existence and a broader scope, SO has only 180 publicist badges. It's easy here because we choose good questions to share.
This question of mine is the first I've seen that's gotten 1k views in about 20 minutes. Most of my other badges took 1-2 days to get there (except the boggle and word cloud questions)
You're right... Copy Editor is a much harder badge to earn (I can tell you that!), but Publicist isn't as pointless as Fanatic
 
9:07 PM
@RM I didn't know that. I got three publicist badges; it took just 4 or 5 posts to do that so I thought it was too easy.
@RM I know you're the only one who got it. I have the feeling I'm editing all the time and I'm only at a third. Perhaps small edits don't count or so.
Perhaps it says something about the popularity of bagels
 
R.M
@SjoerdCdeVries No, all edits to the post count... it is a dry and tiring badge to earn
@SjoerdCdeVries Yeah, that played a role. Bagels are staple in North America (don't know about Europe)... same with Waldo — everyone could relate to it immediately even if they didn't know what was going on
 
@RM I took care to mention Mathematica in every title in order not to draw in people not interested in MMA. Do you feel I shouldn't have done that?
 
R.M
I can see how that would be helpful in a post for the reasons you say and to attract those who have tangentially heard of Mathematica. There are "Awesome X in Clojure" and "Blah in CSS" all the time on r/programming, so this is no different. I didn't do so in mine because I use this account only for link sharing and answering questions related to Mathematica. So if anyone were to check my account, they'd only see a bunch of Mathematica links.
I tried to keep the titles generic or say "programmitically" or "few lines of code" or something like that, so that it is also of interest to someone
If you're using your account for other stuff, participating in several subreddits, etc., then this would be masked by other activity
 
@SjoerdCdeVries Just don't react. The last thing I want to see here is a pack of wolves spamming the site
 
9:23 PM
@belisarius Seems the best way of dealing with this.
 
R.M
I remember a while ago someone mentioned here in chat that I wasn't posting in r/mathematica and in r/programming... actually I was posting in both. I removed my earlier posts and stopped posting to r/mathematica because once everyone here started posting, the frontpage became filled with posts from mma.se and they had too low of a traffic to refresh them regularly.
We don't necessarily see it as a bad thing, but we should remember that it's their community and spamming them with links to our site (even good ones) can be taken the wrong way
It's actually only one guy that seems to have taken it personally... I say just ignore and not respond to any further comments.
 
@RM Always the way. And because MMa is closed-source, we will always be considered suspect.
 
@verbeia They can't see from most of our profiles we've nothing to do with WRI
Perhaps we should ask the WRI contributors to be clearer in their profile though many already do so.
 
R.M
@SjoerdCdeVries I'm happy with what they have added to their profiles... we can't satisfy everybody and we certainly shouldn't be satisfying some random chap on a different site.
Someone is always going to say that I work at WRI and I'm just not acknowledging it because, well, why would I do that if I'm peddling my own product...
 
9:42 PM
@RM Thanks for reminding me of my hanging comments
 
10:39 PM
I just got back. I've missed most of the excitement by the looks of it.
 
acl
10:59 PM
@SjoerdCdeVries I think they're clear enough. Someone's always going to be upset over any given thing you do. I'd let it go, nothing good can come out of arguing on the internet :)
wow, I haven't answered a question in almost a month... once I finish the couple of papers that I have been "finalizing" for the last month I should get back to it...
"once"
 
11:34 PM
@acl A paper is a neverending thing until you get tired and bored
 
acl
@belisarius yes...
 
damn I am trying to solve the catenary vs parabola question. It's incredible difficult for such an easy problem
 
acl
@belisarius I have my hands full teaching myself topology and floquet theory simultaneously (while finishing the aforementioned papers). talk about bad time management
 
@acl You want to learn topo? Read Lacan! :D
 
acl
@belisarius what google returns looks appropriate for my state of mind
 
11:49 PM
@acl hehe
I knew
Most of us here seem twins
I remember I've learn algebraic topology once. My name was Gilgamesh then
 
acl
@belisarius probably why we ended up sticking around.
@belisarius somehow I managed to never learn anything about topology or gilgamesh....
 
@VitaliyKaurov Congrats! Very nice post on puzzles!
@acl Gilgamesh is much more important than topo!
 
acl
@belisarius "Gilgameshian invariants in quantum wires" does have a ring to it
or Gilgameshian insulators
 
@acl When you need some rest, read about something about Gilgamesh. The first tale ever written.
and it is a good one
 
acl
@belisarius now that I think of it, I remember reading a series of books on "mythology" my father had when I was young. gilgamesh was mentioned but I remember little else
