HOOOOOOOOME

@SjoerdC.deVries I linked him to the one you answered, but it is not a dupe. This is different

Man, once started it's just impossible to stop playing with the Penrose iteration:

@Mr.Wizard, 1.276s on my PC your version of minimalFast with the 1000 length dataset, versus 1.30s of my first idea... Your still the king

Bigger advantage on the faster 8000 lengthed dataset

Plus, your first minimal version couldn't be more elegant

Second idea, even slower...

@halirutan Not a Penrose tiling, but something either on chat or meta over the weekend got me playing with:

g = {Circle[{0, 0}, 1/4, {0, Pi/2}],
   Circle[{1, 1}, 3/4, {Pi, 3 Pi/2}],
   Circle[{1, 0}, {1/4, 3/4}, {Pi/2, Pi}],
   Circle[{0, 1}, {3/4, 1/4}, {3 Pi/2, 2 Pi}]};
Graphics[Table[
  Translate[Rotate[g, RandomInteger[3] Pi/2, {1/2, 1/2}], {x, y}], {x,
    0, 10}, {y, 0, 10}]]

and after a bit I started printing them out so I could more easily trace the paths to see how big they got...

@BrettChampion yes, this is nice too. Reminds me a bit of the stuff from Indra's Pearls where they have such rotation and translation groups.

have to sleep. bye all.

This has one of the longer paths I've seen:

Just check my brand new avatar

@Rojo I must have missed something. Where is your first idea? (And the second, for that matter.) I don't see an answer from you. ::confused::

@belisarius Nice! I've kept the same gravatar from the beginning but I'll consider using The Real Logo myself. >:D

@Mr.Wizard I think we may all change our avatars to TRL for the inauguration party. What do you think? Is rebellion an option ? :D

Hi Sza!

Szabolcs

hi, but gotta run!

@Szabolcs Lawyers are here? so soon?

6:36 AM

@Mr.Wizard You there?

6:58 AM

@belisarius I am now; unfortunately Chat pings take a while to arrive if I don't have the room open in a tab.

@Mr.Wizard No problem

There is a theme for a blog posting that is crawling in my head since a few days ago

and I want your opinion

There is a task that I had done a few times: you have a set of homogeneous equations, but you don't know the systems' dimension a priori, and you want to write a solver for that without specifying the number of equations beforehand

May sound silly to you now, but the first time I approached the problem, it was hard

Does it sound too silly?

@Mr.Wizard ping

lol -- sorry, again. I was watching the end of Forrest Gump. :^)

@belisarius I'd read your article with interest, FWIW.

@Mr.Wizard I am sure he ended richer this time

@Mr.Wizard ok. "Introduction to dimensional-free Solving". The first you need a shocking title :D

7:14 AM

That should do it. :0

thanks :P . Good night!

Good night, belisarius.

@R.M Yup, I have the same feeling:)

@belisarius I'm in!

Q: What to do when a new version comes out and renders questions obsolete?

11:55 AM

Morning

@Mr.Wizard, well, I was playing around at real time when I said that... I didn't think it was worth posting late loser ideas. Should I?

Ok, I'm posting the one that got close

@BrettChampion this is pretty neat

Given the huge volume of questions we get here, it's likely that some newer version of MMA may greatly simplify some answers to questions about improving/refining/avoiding some built-in MMA functionality. One thing in particular that comes to mind is the whole legending issue (legending), where e...
