@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}.
 
R.M
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.
 
R.M
You have those in a list?
 
Yep.
l = {{8, 1}, {5, 3}, {2, 1}, {2, 3}, {2, 0}, {7, 9}};
 
R.M
Union@Flatten@l
 
No, it's not to perform the union in all them.
 
R.M
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?
 
R.M
And similarity is only checked between adjacent sublists?
 
Adjacent = Only who's beside him?
 
R.M
yes
 
Nope, it's with all sets.
 
R.M
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.
 
R.M
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?
 
R.M
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.
 
R.M
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
 
 
2 hours later…
7:23 AM
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
A: A curious Plot with IntegerPart[x]

aclI'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...

Q: A wishlist for Mathematica

SergeyFominThe 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.

Q: Is there a way to know how many people already voted in the mod's election?

belisariusI 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...
 
2:24 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?
 
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?
 
@Andrew go ahead
 
Thanks.
Why does this code generate an error message?

> Goto::nolabel: Label A not found.

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.
Thanks for your time.
 
@Andrew You're welcome

R.M
@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.
 
R.M
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
 
R.M
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
 
R.M
@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.
 
R.M
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
 
Canada?
 
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.
 
@belisarius Or you can see this article. :)
 
@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
 
R.M
@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?
please
 
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
 
R.M
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!
 
R.M
@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.
 
R.M
@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
 
R.M
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?
 
R.M
@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
 
R.M
@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
 
R.M
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
 
R.M
@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?
 
R.M
@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
 
R.M
@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
 
R.M
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, 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
 
R.M
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!

Sorry, was busy writing long comments to reply to Leonid
 
@R.M Add one to your bookshelf. It's a wonderful book. And Hardy was a talented writer
And he discovered Ramanujan!
 
R.M
@belisarius Yes, that's how I know Hardy. The book's reputation is second
 
@R.M hardy & Littlewood ... almost one person
 
R.M
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

Q: Why do some questions get a negative vote?

George WolfeThe question on "Advanced Calculus- Ajacent zeros" has a -4 vote and is identified as [migrated]. Other questions have a -1 vote without comment.

That wishlist bit reminded me of this uncle of mine. Back in the day, when he caught his six-year-old hitting the booze (rum, if memory serves), he had the kid keep drinking from the bottle ('twas a big one, see) until the little one was sick and drunk and sorry. The kid's now an adult, and still swears off alcohol to this very day...

However, upon re-reading the FAQ closely I don't see it that clearly anymore. The FAQ (which seems to be still the short ...

 
@J.M. "Fortran" isn't written in all caps nowadays. What are you, stuck in 1966? :)
 
@OleksandrR. I edited for "Fortran" instead of "fortran" ... but then came the old man
Fortran (previously FORTRAN) is a general-purpose, imperative programming language that is especially suited to numeric computation and scientific computing. Originally developed by IBM at their campus in south San Jose, California in the 1950s for scientific and engineering applications, Fortran came to dominate this area of programming early on and has been in continual use for over half a century in computationally intensive areas such as numerical weather prediction, finite element analysis, computational fluid dynamics, computational physics and computational chemistry.

I take that as a maybe.
 
@ЯegDwight You surely can
 
Then I like.
Perhaps I should start working on my Fanatic badge.
I have OVER 42, but not on this site.
 
42 is a nice number
 
R.M
@belisarius but we disregard him because he has over 42
 
9:23 PM
Yeah should have stopped at it.
Time to create a sock and start anew.
 
@ЯegDwight You may disguise your sock as RedDwight
 
No way.
Then I will get pinged all the time.
People ping RedDwight all the time.
They never ping RegDwight, much less ЯegDwight.
 
R.M
pfft... @ЯegDwight
 
Nice. Now ping F'x.
The famous unpingable mod.
 
R.M
@ЯegDwight That was fixed quite a while ago
 
9:27 PM
I know.
And you are well-informed, Eliza.
 
R.M
@ЯegDwight And how does that make you feel?
 
@R.M why do you say and how does that make you feel?
 
R.M
@ЯegDwight Can you elaborate on that?
 
That was an integral part of Take That.
I can elaborate some more. But only some.

ELIZA is a computer program and an early example of primitive natural language processing. ELIZA operated by processing users' responses to scripts, the most famous of which was DOCTOR, a simulation of a Rogerian psychotherapist. Using almost no information about human thought or emotion, DOCTOR sometimes provided a startlingly human-like interaction. ELIZA was written at MIT by Joseph Weizenbaum between 1964 and 1966. When the "patient" exceeded the very small knowledge base, DOCTOR might provide a generic response, for example, responding to "My head hurts" with "Why do you say your h...

Anyway, I must be taking my leave, but it is only after a quick glance at the starred wall that I will do so.

@ChaosGamerΕΛΥēelū Yo mama so fat, she sat on a binary tree and flattened it into a linked list in O(1) time.
I know this is old, and it doesn't use mma functions to boot, but I thought I'd mention it.
 
I love this chat. Reminds me old times, when I was institutionalized
 
Penitentiary? Or soul asylum?
 
Don't remember
 
That speaks volumes. All the way to the 11.
 
Give or take 11

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. Allegedly, after some time even eminent personalities like Johann Wolfgang von...
Anyhoo, I'm outta here.
Have fun and all hail the hypnotoad!

@OleksandrR. Fine, I'm old. Jeez... :P

@belisarius Oh hey, Kermit and friends... :)
 
@J.M. We are Legion
 
@belisarius Sometimes, whenever you use the word "we", I have to think about who you're referring to...
 
The majestic plural (pluralis maiestatis in Latin, literally, "the plural of majesty"), is the use of a plural pronoun to refer to a single person holding a high office, such as a monarch, bishop, or pope. It is also called the royal pronoun, the royal "we" or the Victorian "we". The more general word for the use of we to refer to oneself is nosism, from the Latin nos. It is most commonly used to denote the excellence, power, and dignity of the person that speaks or writes. In pluralis maiestatis the speaker refers to themself using a grammatical number other than the singular (i.e., in...
 
@belisarius Well, part of my confusion is that you've once said that you have an entire load of personalities...
 
10:46 PM
@J.M. Majestic personalities
We^2
 
*facepalm*
 
also WeWe
 
@belisarius Sounds like something I do after drinking too much...
 
@J.M. I had a Swiss co-author that after drinking too much did the writing of his part of the papers. The collaboration period was short.

The "INCREDIBLE!" is a bit much... frogs and toads are known to have good reaction time.
 
R.M
@J.M. I guess that was for the toad reacting to insects on an iphone... I would've thought they could recognize it wasn't a real fly.
But then, I'm a toad and should've just looked at my own cognitive abilities to answer that...
 
@R.M Toads and frogs eat moving things. ANY moving thing
 
I remember assisting in this experiment where we would wave dead bugs tied to a piece of string in front of some frogs. Direct hit, always.
 
R.M
@belisarius No kidding!
