For some reason people are talking about homomorphic encryption.
In game dev, for deterministic simulations like you see in RTSs, you can prevent write cheats by ensuring that the hash of the deterministic sim state matches across players.
You can't easily prevent read cheats though - being able to see the entire map when you shouldn't eyc.
Homomorphic encryption is a way to prevent read cheats.
Fyi!
Last I checked, fully homomorphic encryption was much too slow to use in game dev. There are partially homomorphic encryption schemes though, where you have a subset of operations you can do, vs FHE which can do any operation.
@demofox
Just to make sure you didn't overlook Jeremy Kun's recent-ish posts about low degree polynomial approximation in order to make use of FHE (Fully Homomorphic Encryption)
Does anyone know of any code laying around the net that distributes points on a mesh in a blue noise distribution?
A student intern i work with is looking for this. It's tempting to write it, but im also kinda swamped :X
Mitchell's best candidate would work well here, and would give a sequence instead of a set (use the first N of M total points, for any N), but what makes it more than a 1 hour task is the mesh connectivity, and multiple paths through triangles to the same points that you need to calculate distance between.
Hey software license knowledgeable friends. We recently put code out for a paper that is BSD licensed.
What would happen if some other company forked it and made a bunch of changes/ improvements?
Would it still be copyright EA in the license on their fork? And it'd have to stay BSD right?
Ty, random curiosity :) https://github.com/electronicarts/fastnoise/blob/main/LICENSE.txt
@pkhuong whats the "patent grant for using the licensed software"?
Like if the company patents the work, the license implies that they are free to use the patent as well?
@demofox@pkhuong the wording is such that if a patent troll contributes to an aparche2 licensed project, they automatically grant the right to use any relevant patents to the project. It is meant to help mitigate against a kind of legal trojan horse essentially.
So linkedin as a social media platform... I feel like if I speak my true thoughts as a promethean anarchist, that is going to be detrimental.
And I cannot stand seeing all the people I know to be useless getting prestigious positions.
Mastodon friends, I live for the toots.
@demofox I signed up for linked in once about 14 years ago because a girl I met at a party gave me her linked in handle when I tried to ask her out. I didn't know what linked in was, and deleted my account some time after that.
@demofox I think the thing that motivated me to delete my defunct linked in account was getting a never ending deluge of spam to join sent to my work email despite already having an account
Ok so the internet is the epitome of cache invalidation problems (f5 and dns), and the challenge of naming things (urls). Are there significant off by one errors? :P
@demofox oh nice. i wrote one that pulls items from a set (a shuffling ring buffer, see screenshout for demo output), but doing this without a set at all is excellent :)
@demofox I used to work on a marketing platform that had this competition code dispenser system that would dispense predetermined codes in a random order - it did this by pre-populating a table with millions of rows and then randomly selecting indexes and marking them used... I came up with a stateless shuffling system to remove the setup / indexing overheads. I'd excitedly tell people about it to be met with much eye-glazing ;)
It's nice to see that it's actually a thing in the real world.
Anyone have any tips for repairing or desoldering corroded solder? I've tried applying fresh solder but not all points would take it.
Also, I'm thinking the brown line across the bottom is supposed to be a connection between all of them for ground. I think its corroded to not work as well anymore. Does that look/sound right to people? In the second image, it's the side with a single wire plugged in.
Hey @mbr , I remember you did that LDS thing with integers where you had an integer representation of Phi.
How did you calculate that integer version of Phi?
Did you just multiply phi by the the maximum value the int could represent and convert to int (floor / round)?
I asked my son "if you flip a coin 3 times, is it more likely to get 3 heads in a row, or head, tails, tails?"
He thought for a second and thought "they are equally likely aren't they?"
Oh damn... he is so much smarter than I was.
For folks that know me as "the blue noise guy", I've put together a 50 minute video that talks about many of the things I've learned in my ~decade long dive into noise and related topics - up to and including our latest paper published days ago at I3D.
I hope you enjoy it! https://www.youtube.com/watch?v=tethAU66xaA
@demofox
I know you know what you're doing, but the left side image about "irrational" and "random" reminds me of the famous John Von Neumann quote that I really love:
"Anyone who considers arithmetical methods of producing random digits is, of course, in a state of sin."
