Sorry, fixup:

Fix n, thus corner at distance acn. Now limit a->0 distance is zero.
Distance traveled: acn.
But total distance: ac0 + ac1 + ac2 + ... + acn = a(1 - c^(n+1))/(1 - c)
When a->0, this is zero.

r57shell,
You've agreed that there is a velocity along the radius.
No, I haven't.
It was his interpretation of task, and I just ask him prove relation if he want.
Results are same, but it doesn't mean that you can replace one task with another:
00 = 1
12 = 1
Even though result is same (1), this doesn't mean you can say: 00 is one because 00 = 12, which is one.

sqrt(2)/2 = 1/sqrt(2)
Shame on me :(

Because the animals form the corners of a square at all times, θ is always 45 degrees, and so |vr|=(sqrt(2)/2)*|v| and |vt|=(sqrt(2)/2)*|v|.
Ok now with v and image - clear enough.

@ nth step: Each of them faces the one on the left and moves distance acn-1.
Up to here is fine.
FractalFusion wrote:
Each step generates all the corners of the squares. Letting a→0 causes all the distances above to go to 0, so the corners converge to a curve, and this curve is the one formed where each animal walks directly toward the one on its left (continuously).
Bad reasoning.
Each of corner tends to starting corners. It's easy proovable:
Fix n, thus corner at distance acn. Now limit a->0 distance is zero.
So, nor distance, nor sequnce of sequences {{p0n,p1n,p2n...}} in any lp tends to curve. :)
In lp they tends to 0 = {0,0,0,0,0...}
This is what I had troubles with. Even though I had in my mind possible way to get whole distance passed by.

I don't know the solution to the curve, but it should be rather easy to set up the parametric differential equations. I'll leave that to someone else though.
Many tasks are easy from first view, but later turns out - they not.

Leaved most hard part :)

n(theta) = (theta-theta_0) / arctan(r)
This move is nice! (switching theta and n)
I had troubles exactly with finding how many steps I need to reach point parametrized by t. (not theta)
Even though, I've solve it.
Moving all into exponent nice too.

FractalFusion wrote:
Since the motion vectors always form 45-degree angles to the radial displacement (from the center of the square), radial velocity is always 1/sqrt(2) inward and tangential velocity is always 1/sqrt(2) clockwise (and we also know that tangential velocity is equal to radial distance times angular velocity).
Can you explain in details?

Suppose that four animals are placed at the corners of the unit square and each animal walks at unit speed directly toward the one on its left.
In the end: can you prove that this task is same/related?

I know you don't like easy challanges.
Here is very hard one (IMO)
Get unit square, then do following process:
1) Mark point on each side in clockwise order such that it splits in proportion a : b (clockwise)
2) Connect them to make new square.
3) Repeat.
Question is: what curves formed by verticies of squares when a : b ratio tends to zero?
1) Formulae
2) Is it some kind of known spiral?
3) Proof ofc

Hello everyone. I suggest you quite interesting challenge.
WARNING: I beg you, please don't google for answer. It's known everywhere. Also, if you know already, during reading question, don't participate. Ok? Challenge is exactly in checking your own skills.
Now. The question.
Describe, why it behaves like that:
https://scontent-ams3-1.cdninstagram.com/t50.2886-16/15719832_950998775031904_6513587924682932224_n.mp4
I just stumbled across it today. And, was wondering that it's actually kinda hard to prove this behavior should occur.

Okay, if it's TAS, then it's TAS. But all other still up.

Just showing some "normal" TASes being console-verified live, with proper explanations and commentary, would have been quite ok, but showing something that even regular tasvideos.org users have never seen before is beyond expectations.
If you think that TAS Block goal is to show something that audience of tasvideos.org haven't expected, then they succeeded. Well done.
In addition: for everyone who think that repeating same thing over and over again won't work. Try to apply same argument on speedruning itself. We have seen most of the games multiple times, and people still watch new attempts, and even donate for great cause.

Everyone is entitled to their opinion. Let's criticize arguments, not people.
To be able criticize arguments, you need to define goal at least. I don't know goal, and I'm out of criticizing atm. I know that most of time no one listen. Consider it as feedback.

The perspective of someone who's not a TASer. The perspective of someone who's not a speedrunner. The perspective of someone who's not even very good at computers (of which there are a lot).
Then, simply multiply my opinion by zero. Just because I'm very good at computers stuff. Solved.

And to be fair - TASing has always, to a certain extent, been about taking control of the hardware.
And, to be even more fair, it was always about superplay. And only past time ACE runs appears more often.

For those, who missed what I said at #tasvideos.
This time TAS block was not so fun as before.
In my vision it's because it was actually ACE block, with very small TAS block in before.
Why it was boring starting from portal?
Because Portal wasn't actually TAS (as far as I see, may be I'm wrong),
I don't belive that someone already made tools for windows-rerecording. Or, at least source-engine rerecording. (that is used in Portal)
I know thought, you can record replays straight in Portal itself.
May be I'm wrong again.
But it was looking like playing video, via consoles.
I guess using consoles joypads was some kind of reasoning to be able play video on GDQ. Because I don't see any reason why you would be able to play video on GDQ.
Not to mention, that portal in small window was confusing. Wut? Portal via console? WTF. And was strong feeling of cheating, because you can't actually verify is it real run without cheats etc.
Same thing was with "N64 mario". If it's runned via SNES what is actually not N64, what proof that it was not with cheats, or inacurate emulator, etc.
I know, you can programm any sort of stuff, but for me it was looking as just pervert-geek playing video using his consoles, which is not fun at all.
In my view, ACE should be very small dessert in the end, but this time it was main dish, and actual "push gameplay beyond the limits" was in very short of time, called "NES Classic".
In addition, I guess it was even make confusion to newcomers, when you describe frame by frame edition to push beyond limits, and then, instead of showing masterplay, you showing geek-programming stuff.
If you like some stuff, it doesn't mean that everyone does it too. But for me, it was looking like pushing topic aside: oh how cool we can control several consoles, instead of superplays.
Ah, also! There are some stupid ppl who edit ROMs then recording funny glitches that is appearing in edited ROMs, then upploading on YouTube, name it "Contra Hard Corps Glitches" for example, and ppl watch.
It seems kinda related to what happened this time in TAS Block.

Just to make it clear:
Session Start: Mon Nov 23 21:32:06 2015
[22:35] <r57shell> guys
[22:35] <r57shell> maybe I'm really stupid
[22:35] <r57shell> but
[22:35] <r57shell> http://tasvideos.org/Movies-Stars.html
[22:36] <r57shell> why there movies that actually HAVE stars
[22:36] <r57shell> don't have stars icons?
[22:36] <Fog_TAS> because you're in the star section?
[22:36] <Fog_TAS> seems counter intuitive to have a star when you're in the star section
[22:37] <r57shell> no
[22:37] <r57shell> it's counter intuitive to NOT HAVE
[22:37] <r57shell> star icon for movie that has it
[22:38] <DwainiumB> Fog_TAS: I just wanted to make a quick test movie but it just isn't responsive enough
[22:39] <DwainiumB> I use 5396 anyway, I'll just wait until everything is fixed.
[22:43] <r57shell> Fog_TAS in hope that it will change something, I'll add example from life
[22:44] <r57shell> Imagine I have car
[22:44] <r57shell> and I wanna buy tires
[22:44] <r57shell> studded wheels
[22:45] <r57shell> I opening some shop
[22:45] <r57shell> for tires
[22:45] <r57shell> then, I adding filter
[22:45] <r57shell> studded
[22:45] <r57shell> and SUDDENLY
[22:45] <r57shell> it returns in results
[22:45] <r57shell> studded ACTUALLY
[22:45] <r57shell> but NO info about they are studded
[22:45] <r57shell> it's just hidded "because it's obvious, you had searching studded"
[22:46] <r57shell> it makes really big confusion
[22:46] <r57shell> I would even call support
[22:46] <r57shell> and say, guys, filter "studded" does not work
[22:46] <r57shell> and imagine manager
[22:46] <r57shell> that will tell bs
[22:46] <r57shell> (bullshit)
[22:47] <r57shell> "you was searching studded, so info about studded not need, so we removed it in info"
[22:47] <r57shell> wtf
[22:47] <r57shell> r u mad?
[22:47] <r57shell> ok, I can post that all somewhere, if you point where to post that thing
[22:47] <Zanoab> what extra information could a star icon provide?
[22:48] <Zanoab> (I agree with you for other reasons though)
[22:48] <r57shell> I don't need extra info actually
[22:48] <Zanoab> my problem is when the inverse happens
[22:48] <r57shell> it needs for consistency
[22:48] <r57shell> what inverse?
[22:49] <Zanoab> what if you don't just want to look at star movies?
[22:49] <r57shell> profile of movie should not depend any condition
[22:49] <Zanoab> there is no way to tell it is filtered
[22:49] <r57shell> it should be OBJECTIVE
[22:49] <r57shell> not SUBJECTIVE
[22:50] <r57shell> atm, it depends on page where you looking from
...
[22:55] <r57shell> other example
[22:55] <r57shell> imagine site that removes actor from actors lists in movies
[22:55] <r57shell> when you search movies with actor
[22:55] <r57shell> it's completely mad
[22:56] <r57shell> normal site would highlight it
[22:57] <r57shell> as item that you was looking for
[22:58] <r57shell> it makes conclusion, that info is NOT CONSISTENT
[22:58] <r57shell> not true
[22:58] <r57shell> info - lies
[22:59] <r57shell> because he was there
[22:59] <r57shell> same with movies info
[22:59] <r57shell> when it does not show star icon
[22:59] <r57shell> it simply lies to user
[22:59] <r57shell> that movie does not have star
[22:59] <r57shell> because that placeholder
[22:59] <r57shell> is actually "awards"
[22:59] <r57shell> placeholder
[22:59] <r57shell> and when you see that there is no star icon
[23:00] <r57shell> you making conclusion that it does not have star award
[23:00] <r57shell> that all
[23:00] <r57shell> thx, I'm stoping complain, because I'm tired to tell reasonable things to those who just don't listen
[23:00] <r57shell> the end
Today:
<r57shell> I'll explain for those who don't understand where confusion coming from
<r57shell> you select stars filter
<r57shell> then few seconds looking page
<r57shell> then suddenly, wait' they are not starred!
<r57shell> clicking browser back
<fsvgm777> Because it's in the URL.
<r57shell> ok I wanna stared ones, clicking on stared link
<r57shell> checking again, no stars hmm
<r57shell> clicking on some of movie
<r57shell> it opens single movie
<r57shell> with its card
<r57shell> and you see, it's really stared
<r57shell> WTF you think.
<r57shell> then, if you thorough enough, you'll go on default list for games, and will see there same movie with star, and compare with list of stared ones, and all this confusion dissapears
<r57shell> but WTF still stands
<r57shell> so, my reasoning exactly:
<r57shell> movie card should be same inregarding to page, because that's more consistent/makes more sense/is clearer for the viewer

After submitting the movie, I was so happy that I suddenly started singing that song, and decided to post it as a primary encode while the actual one was still processing. Related enough?
Related only for you. How is this song related to TAS, or may be success?
In looking for relation, I started to search three ppl, and what they do in 3-way.
First what I found is that fact, that in authors is three ppl.
But I thought it's wrong way for understanding what it means...
Need to describe more detailed?
