@Beli Can you help me with a simple thing?
(seed = 343808)
Give the id[] array that results from the following sequence of union operations
on a set of 10 items using the quick-find algorithm.

8-1 5-3 2-1 2-3 2-0 7-9

Recall: our quick-find convention for the union operation p-q is to change id[p]
(and perhaps some other entries) but not id[q].
I can understand how I'll make these unions.
But I haven't a sofisticated way to make the unions, for example: Create the set {2,3,0} from {2,3} and {2,0}.

4:52 AM
@GustavoBandeira `{2,3} ~Join~ {2,0} // Union`?

@R.M Yep, But I want to create it for all the sets here: 8-1 5-3 2-1 2-3 2-0 7-9
I would do it with If - dunno if there's another way.

You have those in a list?

Yep.
l = {{8, 1}, {5, 3}, {2, 1}, {2, 3}, {2, 0}, {7, 9}};

`Union@Flatten@l`

No, it's not to perform the union in all them.

4:54 AM
oh, ok. I don't know what you're doing then... I just saw the last msg

It's to perform the union on them if they share similar elements.

{2,3} {2,0} = {0,2,3}
{8,1}{5,3} = {8,1}{5,3}
Now as we have the set: {0,2,3} we should perform the union also with {5,3}
Until no further sets can be created.
Was I clear?

And similarity is only checked between adjacent sublists?

Adjacent = Only who's beside him?

yes

Nope, it's with all sets.

5:04 AM
Ok, here's one straightforward way:
`l //. {h___, a_List, b_List, t___} :> {h, Union[a, b], t} /; Intersection[a, b] =!= {}`
Note that this uses `//.` along with `___` which is very inefficient and will be slow for large lists, but is simple to follow and gets the job done for small lists. There are probably more efficient ways, but I'm too sleepy to think of any now
For your list, this gives `{{0, 1, 2, 3, 5, 8}, {7, 9}}`, which looks correct

@R.M I'm looking at this in a Algorithms course. Do you think it's safe to use functions such as intersection and union? - I believe the course has a more generalist approach, and I still dunno if such functions are available in other programming languanges.

Well, it doesn't matter if `Union` is written simply as `Union` or as a bunch of for and if loops as long as they do the same thing. If you want, you can expand out the logic for `Intersection` if your prof wants pseudocode... However, if the focus is on algorithmic complexity, there are probably better (procedural) ways.
I think you should clarify with your prof if they expect you to write procedural code. Most probably they will, because it's easier for the students to understand the inner workings. Like how you can't get away using `Sort` in a lecture where the focus is on sorting algorithms...

@R.M any word on whether there will be a Town Hall chat?

5:21 AM
@rcollyer Probably before Wednesday:
12 hours ago, by F'x
@belisarius yeah, I already contacted Grace Note, and he feels (and I agree with his reasoning) that the chat cast cannot be any later than Wednesday… otherwise too many will have already cast their vote

@R.M Ok. Thanks for the help.

No worries :)
If you want help with breaking that down into much simpler and efficient procedural constructs, you could ask at SO, for instance (explain in words what that code does) and use the tag
belisarius frequents that tag too, so he might answer it for all you know, but don't forget that SO is filled with people who are good at this

What's the meaning of clicking "This is a favorite question"? I used to think that it's an enhanced upvote but these days I find that I seemed to be wrong…

7:50 AM
@xzczd Favorites are purely for your convenience and don't confer any rep points or other status on the poster. The list is part of your user profile (i.e. here); it is basically just a way to bookmark questions that you found useful. I suppose the list is visible to other users so that others can see what your interests are.

8:38 AM
@OleksandrR. Ah~I see.

2 hours later…
10:35 AM
@Oleksandr: looks like you won't have to ask that question after all... >:)

11:28 AM
@J.M. @R.M - You two seen the invite for the town hall?

@J.M. we'll see. I was wondering why he thinks a 1500-point plot takes too long, and then I realised: he's typing the points in manually! That and the use of a finite difference derivative on noisy data make me wonder whether this will be such a good opportunity after all...

@GraceNote I haven't checked my e-mail today; wait...

12:24 PM
@OleksandrR. Definitely not. You need to smooth out the points first, but not too much, or you'll lose the peaks

Numerical differentiation has always been unstable (even more so with error in the mix), so that guy's request for "accuracy" might in fact be a tall order...

ld = {1/102960, -(8/45045), 2/1287, -(56/6435), 7/198, -(56/495), 14/
45, -(8/9), 0, 8/9, -(14/45), 56/495, -(7/198), 56/6435, -(2/1287),
8/45045, -(1/102960)};
g[x_] := x + 1/2 Sin[x] + RandomVariate[NormalDistribution[.1, .05]]
Plot[{g[x], 10 g'[x], 10 g''[x]}, {x, 0, 8 Pi}]
t = Table[{x, g[x]}, {x, 0, 8 Pi, 8 Pi/1500}];
ListPlot@ListCorrelate[ld, t[[All, 2]]]
ListPlot@ListCorrelate[ld, MovingAverage[t[[All, 2]], 30]]
Numerical differentiation after smoothing

12:49 PM
@J.M. Of course it fails gracefully for the second derivative. You need to smooth the first, losing precision and then take the first derivative again

@belisarius Right, so I'm often leery of "differentiating data"...

@J.M. Mma uses an eighth order central method for that, but it's not enough for noisy data
too much weight for the central points
@J.M. Now you should ask me how I know about the eighth order :D

@belisarius Funny, I was typing that precise question... ;P

@J.M. I found it here, and posted as an edit to @acl's answer
14

I've completely overhauled my answer. I believe this now answers the questions posed (why mma thinks the violet line is the derivative of IntegerPart'[x]). Let's first look at ND, simply because its internals are easier to access and we may obtain some insight. Try: Needs["NumericalCalculus`"] ...

(There is of course the mantra "higher order is not the same as higher accuracy"...)

12:55 PM
of course :)

@belisarius 2nd derivative:

@OleksandrR. smoothing out the first one, I guess

@belisarius no. Directly fitting a least squares 5th-order polynomial for each point using a moving window and using it to obtain the second derivative. (Savitzky-Golay filtering!)

@OleksandrR. Ah, yes. That is the other way

It's a little bit shocking how severely the significance of the noise amplifies for each successive derivative. For the first derivative, I can use a 100-point window (which is still very long); for the second, I needed 240 points.

1:03 PM
@OleksandrR. Smoothing the first derivative, here is the second:

@OleksandrR. Right, hence the bit about differentiation being a "noise amplifier"...

@OleksandrR. It's natural once you think that you are really amplifying the noise relative value by subtracting the function values
he ..

More structurally, you're dividing two tiny quantities, one of which is obtained through delicate cancellation. Hard to win there...

@belisarius S-G first derivative:

nice

1:10 PM
Here is Lanczos's take on the matter...

(The scaling between the first and second derivatives is not right and the endpoints look odd as well. I never use the derivatives myself; only smoothing, so although I fixed this I don't have the fixed code available right now.)

@OleksandrR. I once made good money from a company that wanted to develop a scale for weighting trucks on the go using those tricks

@belisarius As in, the trucks roll over on the device and the weight registers on some display?

@J.M. Yep. There were several problems. You need to weight each tire pair, the scale is very narrow (1 meter), and the truck is going fast and oscillating like hell
It was a nice problem
And you need to do the weightings in real time
with amicrocontroller

@belisarius Yes, I can imagine the trickiness... :)

1:17 PM
@J.M. Then they wanted to do the same with trains ...
ha!

@belisarius Good luck with that, indeed... :)

@J.M. Tell that to them. We told them that a different approach was needed
@OleksandrR. To get perfect stability that should be done in vacuum :)

@belisarius :D

1:33 PM
I'm still biased towards levitating with magnets, tho...

The system is the best on the market, but is far from perfect. Let's create a wishlist as on AUGI (for AutoCAD) to make Mathematica better.

I know the results are private until the election process ends, but is the same criteria applied to the number of voters?

@J.M. optical levitation is my favorite. I just like lasers, I think.

Even if they're attached to sharks? ;)

1:50 PM
@OleksandrR. That's far too easy

@R.M Do you see this question?
This time I flagged it properly and did not make fun of some poor matlab guy ;-)
And whooosh... it's gone.

@halirutan Guy self-deleted...

2:13 PM
:)

2:24 PM
@belisarius yes. Spot the errors. :)

@OleksandrR. I will ... when i need the code :)

That being said, it's still better than all the other S-G code you will find with a Google search for "Mathematica Savitzky-Golay filtering"

@OleksandrR. There was a native implememntation in 5.3

@belisarius 5.3?

@J.M. no, sorry, I misread the title

2:31 PM
Okay, you scared me for a moment there... :)

@OleksandrR. I've seen that before, and I love it.

2:47 PM
Hi, may I ask you a quick question?

Thanks.
Why does this code generate an error message?

Goto[A];
Print["start"];
Label[A];
Print["A"];

Does `Label` have to precede `Goto`?

@Andrew First a warning

The output, I think, should just be "start", but it seems I am misunderstanding `Label` and `Goto`.

Goto[] is usually not needed in good Mathematica code ...

2:52 PM
@Andrew in the FE, each line is interpreted as a separate expression if not enclosed inside something else. Enclose the whole lot in parentheses or anything else and it will work as intended.
(Or just put it all on one line.)

And don't use it!

I would like to write a script that has two sections, A and B.

Why do you need GoTos?

(rather than two scripts)

If[ condition, f[x], g[x]] will do

2:54 PM
I've a good feeling that your algorithm can be rewritten to avoid `Goto[]`...

I would like to have variables `doA` and `doB`. If `doA` is `True`, then I want to skip to section A.

Hrrrrrrrm

If `doB` is `True`, then I want to skip to section B.

make each "section" a function ...
Code in Mma shouldn't be "cascaded"
except in very short snippets

I just find the braces so complicated; sections A and B are so long that if I put either an `If` or a function, the braces just become complicated and the script becomes hard to read.
Or brackets, rather.

2:57 PM
@Andrew That's what spaces and formatting are for.

I guess all your variables are global ...

Yes.

They shouldn't

...and you think `Goto[]` makes things easier to read? You want the reader of your code to be jumping all over the place as well?

So to make variables local, I would have to use a separate function and `Module`?

2:58 PM
try to format your code in small functions, each one with its scope

ok.

@Andrew You're welcome

@bel, `With[{m = 1, s = 8, n = 16}, CoefficientList[Normal[Series[x^s Log[x]^m, {x, 1, n}]], x]]`

@GraceNote no, but if you want a time from me, anything between 7am–10pm PST should work, as long as I know the time a couple of hrs in advance

@R.M Current option is looking to be 10:00 UTC tomorrow. Which, unfortunately for you, is like, 3:00.

3:12 PM
ugh. No worries

Well, don't worry. It's a bit late and I really need to schedule it sooner rather than later. As I've told F'X and Verbeia already, you don't need to attend the live event

I bet it'll last 5 mins before the town hall chat turns into an infix pun thread
2

You can always show up afterwards (which won't be too long for you) and just answer all questions posed there

@GraceNote when does Tim usually create a transcript? The same day or after all have answered?

@R.M Latter
As long as people don't take, like, four days to answer.

3:18 PM
Ok, thanks. I might also pull an all-nighter... have some other stuff that I could get done

@J.M. Nice!
I have to think why ... :D

Alright, so, based on submissions, we will in fact run the Town Hall Chat at 10:00 UTC tomorrow. This is 6:00 EDT, or you can just check out this handy page of various time points

@GraceNote 7 AM here ... Arghhhh

Argentina

3:31 PM
Ah. I was going to guess "Some area of South America" next, but I don't actually remember which countries are easter-most. I only really know where Venezuela and Chile are

@GraceNote Don't worry, if economy continues to go this way, we will vanish from the map soon

That sounds pretty ill
...y'know, Juan (moderator on Gaming, we worked together since beta) lives in Argentina too, yet I never thought about the fact that he is an hour ahead of me, and always has.

@GraceNote One hour is bearable. The real problem for us is working with Middle East or Indian guys. Painful.

Mmm

@GraceNote Ah, beautiful...

3:38 PM
@GraceNote o_o
I will prepare copious amounts of coffee.

@TimStone I'm pretty sure I've gotten you up at worse hours

Actually if it's in the 1-3 am that's usual awake time for me, unfortunately.
On the plus side, waking up early might actually motivate me to get out and get things done tomorrow, so this works out nicely.

@J.M. that would not be fair :)

@belisarius True story: I figured the method out on my own, and was a bit disappointed to find that I was three years late...

3:41 PM
@TimStone I wonder if I could be able to discern what "tomorrow" is if I get up at 3AM

@J.M. damn you far east and upside down folks

@R.M Heh, sorry about that. Snack time was a pretty convenient choice...

@J.M. You are no alone Born in a poor Brahmin family, Ramanujan's introduction to formal mathematics began at age 10. He demonstrated a natural ability, and was given books on advanced trigonometry written by S. L. Loney that he mastered by the age of 12; he even discovered theorems of his own, and re-discovered Euler's identity independently.

Feck, I'd kill to have at least a tenth of Ramanujan's ability...

@J.M. Hehe ... a tenth is too much

3:51 PM
Guys, I dont want to create a post. Could someone please tell me how to transform the output of a "Panel" into an image?

Rasterize@Panel[1]

Thanks so much!

@SosiKun You're welcome

I was thinking it should be something really simple and creating a post about this would just be a waste

it's ok

4:01 PM
@J.M. interesting to see that the wishlist has already turned into a combined bitchfest/list of "nice to haves" in everyone's personal field that they could just as well implement themselves...

@OleksandrR. Yes, hence my grumbling in the comments. Oh well.

@OleksandrR. And no reference to the price tag yet

4:16 PM
@OleksandrR. exactly, but it's good to let this one devolve for a bit before putting it down... It serves as a good counterexample for those that want to allow soft questions.

@R.M, I just went to look at your "yo momma" jokes. ahahah those are awsome!

@SosiKun heh :D It's an on and off thing, so they're not all in one place... this might have some more from everyone

@R.M Now your chat msg is self-referenced :)

@R.M I think soft questions in general are potentially acceptable, but this is pretty obviously going to serve more of a cathartic than productive role. One could argue that it's still net beneficial to the community, even if it doesn't fit into the SE "vision", I suppose.

@belisarius :D
@OleksandrR. well, since it's on meta, let them have at it... we needn't be sticklers for main site's rules on meta.

4:23 PM
@R.M But meta's purpose is not like that

but it is funny though, that the first responses were a few genuine and general ones – code formatting, palette docking, tab views. It quickly turned into a "This kitchen sink isn't big enough! I need a support vector machine built into my sink to learn about my food crap"

Hm? Wishlist?

@belisarius Oh, I agree... I'm for eventually closing it down. Just that I'd do it a bit slower than on main (everyone's way into it now and you'd only burn most of them)

I promise not to dive in and go all authoritarian override, I'd just like to look at it

@GraceNote here

4:27 PM
Thanks
Oh. Hooboy. Something like this...

kill it mercilessly

Let me see if I can drag up something from Robert on the subject - if my memory hasn't failed me, he wrote a very simple and understandable explanation of why not to do this kind of thing to your meta site

Leonid strongly believes that the votes from a strong community like this will influence WRI's choices... well, I'm a little pessimistic on that. I don't think Santa Wolfram is going to shower these goodies on us just because we're good boys, because other wise, we'd have gotten multiple undo 6 versions ago

@GraceNote First: Because it's useless

@GraceNote we know it's useless and will kill it... we're just discussing when to kill it.

4:31 PM
@R.M I would counter that "Strong backing in the form of detail and good arguments would be more useful than something as bland as vote count"
Y'all know it's useless, but do you have a good means to present why it's useless to the rest of your community when you bring down the hammer?

Unconscious people don't need explainin' to.
2

I'd like to make a wishlist for Coke too. Which one is the appropriate meta?

@R.M WRI only has a finite number of staff and I'm sure Stephen Wolfram has already compiled a list of to-do's for them as long as all of our arms put together. Nonetheless it is at least potentially possible that one or a very few of the ideas presented gain much more support than anticipated and are worth pursuing. However, I have the feeling that this will serve mainly to demonstrate to people that not that many others really care about the same things they do.

I downvoted the question. I think it's the first thing to do

Hm. Can't find the post easily.

4:39 PM
@GraceNote What was it concerning?

@GraceNote It's ok. If it comes down to having to write it again, I'm sure reasonable folks will come to the same conclusion.

@TimStone A basic explanation which I believe was from Robert, back during our first beta sites, on why you shouldn't use a per-site-meta as a home for stuff you wouldn't allow on the main site (this probably came up for "Hidden Features" and recommendations on Web Apps first)
It's entirely likely that this was conducted entirely on chat, though

@belisarius `javascript:\$('.vote-down-off').click()` for instance, maybe? :D
@LeonidShifrin I disagree with you about the usefulness of this question and its answers. I personally don't see this having much impact (if any) on development efforts. — Brett Champion 34 secs ago
There we have it, folks!

@R.M too obvious
@R.M If WRI accepts a Q/A site to manage their priorities, should I compete with them, I could make my employees vote for a `Graphics4D` feature

I'm voting to close this partly based on Brett's comment above. But more importantly, this is quickly turning into an "It would be nice to have builtin functions for my specialized research area", and each one has a few of their own. All that this has highlighted are personal preferences and nitpicks and very few of those are actually beneficial to the community as a whole. Inevitably, in such one-topic-per-answer posts, the first few to answer will always come out at the top because that's what everyone sees first and something more relevant that's posted later will be buried (or never rise) — R.M 4 mins ago

@R.M followed

@R.M, thanks buddy! Now that I found that, its probably that I say my work day has ended :P
it's probably better that*

"We are offline", apparently. More server moves?

@OleksandrR. Not here.
@OleksandrR. I talked too soon. Down now

@GraceNote Hmm, yeah...I'm unable to find anything anywhere. So it's either somewhere that I can't see it, or I'm not looking for the right thing. Ah well.

5:17 PM
hey guys, i know this is probably not the best place (given the math.stackexchange.com), but do you guys know of any really cool places to study linear algebra or calculus?

@SosiKun Yeah ... a book

ok, thanks so much.

@SosiKun You're welcome. Do you want some book recommendations?

I am using Gilbert's "Linear Algebra and its applications", but I was looking for more information to complement that.
mostly because sometimes I get tired of reading from the same place
so yes, I welcome all recommendations ;)

@SosiKun This is the better introductory book to linear algebra I know of

5:27 PM
@SosiKun try MIT's OCW or coursera/udacity/iTunesU... the videos might be useful as a companion to a book

Thanks, I will check it out!

@R.M Shut up toad. I get 10 cents for each recommendation
I am a recommendation turk

Thank you @belisarius and @R.M, I'll definitely check them out!

And he discovered Ramanujan!

@belisarius Yes, that's how I know Hardy. The book's reputation is second

@R.M hardy & Littlewood ... almost one person

I must admit, I like the older texts more than the newer, bite-sized info on a page books. The development of the material and guidance into the way of thinking is far better in older texts. Recent texts seem to have shifted to a less verbose, more direct style of writing (because no one has time to read), but it often comes with a loss of clarity

4711 is a brand of Eau de Cologne by Mäurer & Wirtz, a subsidiary of the Dalli Group owned by the Wirtz family. It is produced in Stolberg near Aachen, Germany. History According to a legend, on 8 October 1792 a Carthusian monk made the merchant Wilhelm Muelhens (1762-1841) a wedding gift: the secret recipe of a so-called "aqua mirabilis", a "miracle water" for internal and external use. Muelhens then founded a small factory at Cologne's "Glockengasse" and established the first "Eau de Cologne" as a remedy.
