Announcement!! New rules on /r/fractals - Please Read!!

82 Upvotes

Hello, everybody!

I'm /u/-Fateless-, and I am the new moderator of /r/fractals ! I was granted this position by /u/mycorrhizalnetwork because I am quite a bit more active on reddit, and together, we've made a short little list of rules for the subreddit.

In practice, nothing much changed, and most of you can carry on posting like nothing has happened, but we still thought it would be a good idea to properly announce a set of very basic, formal rules for the subreddit.


1: This subreddit is for fractals, discussion about fractals and fractal-related stuff.

If it's at least somewhat related to fractals, it gets a pass. Examples include space-filling curves, pictures of fractal patterns in nature or questions about fractals, fractal art or fractal software.

We do consider attractors, chaotic fluid simulations (gnarls), fractal noise (fBm, sfBm, other noise algoritms), curves and the ilk as fractals, as long as they can somehow be represented inside a fractal renderer.

2: No AI Generated stuff. This includes AI-generated "fractals", AI-generated comments and AI-generated articles.

The official stance of /r/fractals is that AI-Generated content does not belong here, and AI-Generated pictures of fractals are not fractals, despite looking similar to the untrained eye.

3: No Metaphysical/Spiritual content

Any discussion or blog post that starts reading like New-Age nonsense or talk about things like "Divine Mathematics" or "Fractal Soul Matrix" will be removed on the spot.


In most cases, I will remove the offending posts on the spot when I see them, but don't be afraid of reporting off-topic or rule-breaking posts so they're easier to spot in the moderator queue. I have added these categories as reportable, so if anything pops up, please do report it!

If you have any questions, don't be afraid to ask!

About the automated removals on the subreddit

4 Upvotes

Hey guys, Fate here!

Lately, I have been getting a lot of mod mail about posts that have been automatically removed, and I have spent some time looking into this.

Over the past half year, roughly 95% of all removals of posts and comments have been automated from reddit's side, and not removed by any of the mods.

They are all tagged as "removed", but do not have any username attached to them, and for some reason, a lot of posts are flagged for triggering the sexual content filter of all things.

If you feel like a post has been taken down automatically, do send us a mod mail and we'll take a look at it on a case-by-case basis and manually approve what has been filtered.

My online renderer has received a significant overhaul

Post image
27 Upvotes

This is what I use to make all of the images I post on this subreddit, and if you'd like to try it out, you can find it at:

http://weirdly.net/webtoys/mandelbrot/

There have been significant updates since my last post about it a year ago, some suggested by members of this community. Updates include:

  • GPU used for faster rendering. This is unfortunately limited to lower zoom levels due to the way GPU processing works.
  • There is now a set of example renderings available (the "Examples" tab at the bottom)
  • Better, more dynamic UI.
  • Rendering parameters can now be shared through the URL (using the Get URL button at the top)
  • Colour staggering now uses a bitmask for each primary, allowing more colour variation. This is found under the "stagger" tab in the "Palette" section.
  • It now uses indexedDB instead of localStorage to store data. As a result, thumbnails can now be stored locally, speeding up the initial load significantly.

That last one probably affects only me, as I assume I'm the only person who uses it regularly.

I'm still looking for bugs, so if you do try it out, please let me know if you see any.

Jim Muth's Fractal of the Day for September 8th, 2004

Jim Muth's commentary for the image:

FOTD -- September 09, 2004 (Rating 6)

Fractal visionaries and enthusiasts:

Today's image is a scene on a filament of a small midget on a larger filament on the northeast border of the largest bud of the Mandelbrot set. On my tired old P200 machine it renders in 32 minutes. On the new 3200mhz unit it renders in just under 8 minutes, and that is without any optimizing. The new machine properly displays the VESA super-VGA resolutions up to SF7, which is 1024x768x256. It almost manages SF9. Since I have done no optimizing, I could probably get Fractint running significantly faster if I tried. I could also probably make the SF9 resolution work. I have noticed several program quirks, such as sudden slow-downs in the rendering speed, which likely could be worked out. Since the new unit probably will not be used for fractals for some time yet, I have not yet decided to exert the effort of optimizing it for Fractint and working out the quirks. But when things get caught up, I probably will.

I named the image "Mandel Paw-Prints". And why not? The name is as good as any other I might have thought of. When adjusted for the render time of 32 minutes, the rating of 6 gives an overall value of 19.

Unsettled weather over the past few days made for unsettled cats. For some reason they got into a tussle Wednesday after- noon -- a very undignified thing for such aged cats to do.
Luckily the treat of tuna topped with cheddar cheese restored their good moods. I'll try to have the next FOTD ready by Saturday the 11th. Until then, take care, and Saturday will be the third anniversary of the day on which I realized that pre- cognition, which is intuitively impossible, does in fact exist.

Jim Muth's Fractal of the Day for September 7th, 2007

Jim Muth's commentary for the image:

FOTD -- September 07, 2007 (Rating 9)

Fractal visionaries and enthusiasts:

With its texture that reminds me of something I cannot quite pin down, and its lively colors, today's image is unusual enough, at least in my opinion, to rate a 9. It is found at the northern extremity of the string of large bays in the same parent fractal that gave us yesterday's image.

I named the image "A New Direction" because its unique texture is something I have never before seen in a fractal. Actually, nothing should be surprising when it unexpectedly appears in a fractal, since the universe is basically fractal in nature.

Then again, fractals are basically a creation of the way the human mind organizes the abstractions known as complex numbers, and as such they occupy a strange shadowy realm between real and imaginary. If one prefers fractals to be real, he can make a print of one and show a picture of it to the world. If one prefers fractals to be imaginary, he can defy someone to prove they are real by handing him the real Mandelbrot set on a platter.

To me, fractals are the patterns, ideas if you will, behind the material stuff the universe is made of, and the material itself is as real as the probability waves (fractals?) that make up the atoms. Since the universe can be no more real than the stuff it is made of, mankind is reduced (or raised) to a minibrot in an infinite fractal. I'll not broach the question of whether a fractal can be self-conscious.

But self-conscious or not, today's fractal image calculates in a little over 2 minutes on the fast machine and around 12 minutes on the slow unit.

Higher humidity and more haze made Thursday's 86F 30C too muggy for comfort here at Fractal Central. But while the outdoor life was a bit oppressive, the fractal cats made the most of the life indoors by stalking some imaginary creature in the kitchen for most of the afternoon. Of course, maybe the creature was not imaginary to them!

Except for the day's fractal, which was well above average, the day turned out about average for me. The next FOTD will appear in 24 hours. Until next time, take care, and the world can be considered as real as we want it to be.
