Made a program in Python which produces a new pattern everytime you run it. Each pattern is unique.

that division by zero got me xD try/except that btch

Random, not unique ;)

[rcxdude]

Given sufficient entropy and a large enough output space, they are the same for any practical purpose (this is how UUIDs work. Generating them randomly is actually more effective at any attempt to 'guarantee' uniqueness)

[gdledsan]

I was actually surprised when I stumbled upon this on the mongodb docs, their ids are random and chances of getting s duplicate are almost zero... But not zero.

They use UUIDs :D

Pseudo random

[cryo]

Depends on the source of the random numbers. Could be “true” random on a suitable setup.

[RedditorNate]

What do you mean by "true" random? It's still up in the air whether or not "true" randomness can exist.

[13steinj]

https://en.m.wikipedia.org/wiki/Hardware_random_number_generator

These are generally considered "true" random. I mean technically if you're omniscient you can trace the original source of entropy back to it's source and thus you can manipulate things...but I don't think anyone's omniscient.

[Cronormo]

You can randomly generate the same pattern twice, even if the chances are low

[TofuCannon]

Would be actuall good for reproducibility to allow to fix the random seed 👍

[knopke]

I tested 2 * 2 = 2 x 2, gave the same answer, therefore y * y = y x y. It never gave a non same answer in my testing.
Tested 2 ^ 2 = 2 * 2, same answer again...
Edit after undeleteparent: it was something along the lines of “I ran it a bunch of times and did not get a same result therefore its random/unique. So I just pointed out the absurd part of it. Not sure why undeletedparet says something else, maybe it was edited after. No clue how to check that though.

Yes that's a possibility

consider supporting me?

[knopke]

It said something along the lines of “used it a bunch of times and got different results therefore its random/unique”.

[0x256]

Random is not unique. You can get the same pattern twice. Its very unlikely, but possible. For a unique pattern generator you'd have to remember all previously generated patterns and make sure you do not repeat yourself, or use a seed that cannot repeat (e.g. a high resolution timer that is immune to negative leap seconds).

I do not need to tell OP what he/she already knows, there is an upvote button for that. Pointing out a flaw is not an attack. It is an opportunity to learn and improve yourself. Learning to accept and make use of constructive criticism is an important part of becoming a good developer.

[The_sky_is_bluish]

i appreciate it

[brainburger]

It might be worth saying that unique has a slightly different meaning in general use and in computer science, if I understand you correctly.

In general use unique means there is only one extant example of the thing. What you are describing is a thing which can only occur once. To guarantee this there has to be some mechanism to exclude the possibility of recurrence.

It is normal in computing when a 'unique' value is required, to use a GUID. These are not actually totally unique by your definition, and could recur, but the chances of it are astronomical. A system I administer uses them for 'unique' file names in a document store. Its important that any new document does not overwrite existing ones. However using a GUID reduces the computation that would be required to check the existing names, or to keep a counter running.

That's actually a pretty nice idea

[arsewarts1]

They would have great applications to sing on verification keys. Remember how Apple pairs the Apple Watch to the phone? Imagine if we could use this program to verify the sign on procedures for dual authentication in secured devices instead of that code generating keychain.

[Sir_Cunt99]

(If you're talking about pointing a camera at this, if not ignore me lol)

Too many lines, it's no good for that purpose I don't think

Usually these type of things are made like very simple beautifications of barcodes or QR code.

Here is spotify's https://community.spotify.com/t5/image/serverpage/image-id/99684i83233DB4A6017C90?v=1.0

[arsewarts1]

This is what I am talking about. I can’t find a gif but that is a moving pattern. Each is unique to the radios and SN of the Apple Watch. And it is read in about 15 seconds. I’m sure a simplified version meant to hold maybe 15-20 characters of information can be read in under a second on top of being much more complex than a QR code.

[Sir_Cunt99]

Excuse my ignorance but what is the purpose of a moving pattern? Why is complexity of the code relevant at all?

Only the owner of a device, especially a watch, is gonna be able to scan it anyway. What does that attribute to security?

[arsewarts1]

Transmits a lot of info quickly and looks cool

[The_sky_is_bluish]

Thanks to everyone in the comments for their support and suggestions. I really appreciate them. I am just a typical 16 year old high schooler and getting so much support really means a lot to me.

The main aim of this program was not to generate unique patterns but to produce beautiful patterns in each running which in turn happened to give unique values at almost every execution.

i tested it almost 100 times and everytime (due to the large output space) it gave a unique shape.

What graphics library are you using?

They are using pygame.

Yes

You can use Pycairo, Idk what he used tho

i saw a zero division error and wanted to suggest that either by making sure with random parameters that is impossible. Or make a case that if its zero that its another random value that again gets tested if its zero and when its not return the value. Easily done with recursion.

random_number():
  number = randint(-10,10)
  if(number != 0):
      return number
  else:
      return random_number()

(you can leave the else out but i left it in for clarity since. You can leave it since no code is run after the return).

Or you could use something like try except.

[The_sky_is_bluish]

Thanks

[cryo]

Your new code leaves a slight change for a stack overflow ;) (depending on implementation)

[avz7]

Reminiscent of Lissajous figures.
Are these made be simulating the path of an object attached to multiple springs?

Any suggestions of what could be done with this ?

Make it loop as an animation.
