Terrible!

Ah, almost forgot usage.. it's only an 8-bit version, with input values 0-255 mapped to 1-256 (to suit octaves arrays... and other stuff ;) and yeah it works as an xor-not lookup (table? / vector)



Xorn = xornBuilder;

outP = Xorn((dataX2 .- 1) .* 256 .+ kS2);

does 11mb in under 7.5sec [key and data in memory (not tested accurately ! will be less =) -> output on file]

Wonder if /prog/ recognises this...? I posted a similar system in C once.. =) It's not a particularly good PRNG, but it has other 'special' properties ;) namely it is a Pseudo-Random-Factorial-Set-Generator, used for the Jar/Cell construction =D

And anyhow, people shouldn't freak out so much.. I mean shit, people have Assault rifles for self-defence, nations have nuclear weapons and black-op's, secret police and nerve gas, and you're looking at me all suspicious-like because i can send a bloody secret message if the need arises?

Similar story for nukes, one guy has a nuke, then everybody else needs them in order to reach the stalemate scenario and not get wiped off the face of the earth... but some retard will still end up using them regardless.. So I blame all the retards that didn't disarm, causing that situation to unfold.
Cryptography itself is not a weapon, the grandest algorithm in itself couldn't manage to harm a fly, even with ten people operating it.

And anyway, shouldn't you blame all these people misusing their cameras for much of the porn out there?

Name: Anonymous 2013-01-12 1:15

perhaps even Along with society/culture itself...
I've seen places on tv, remote tribes where everyone basically just walks around pretty much naked anyway. I'd doubt that they have any concept of porn, let alone any real trouble with modern sicknesses of the mind. Anyone who did do something sufficiently evil would most likely have it beaten out of them with a large stick, and that would be the end of it =)

I'm a real outcast, Luke. I don't fake it. You don't know how much hate I am capable of. Yes that's sad, but I don't ask anybody to pity me.
I hate your ... retarded =D ... heehee syntax =D
Why did you have to create more than a hundred threads about panic attacks and other teenager's problems on what used to be a place I enjoyed? Do I care? Do I visit a programming board to hear about that shit?
And the fucking Touhous, and the pedophilia (well, you're a kid yourself, but still)... The constant flow of shitpost I had to cope with.
You've got 142 friends on your fucking facebook account.
The gorgeous australian sun, the beach, your stupid surfer outfits... Long hair, sun tanning, nigger lips. You don't look too bright, sure, but most of the retarded girls in your neighborhood would find you cute. Your family seems to be normally wealthy. So, what's your fucking problem, spoiled little western brat?

Don't suppose someone could explain the 'WASP' term? I think i can guess the 'doxed' one, so i won't ask.

>>26 That is kind of sad about the hate. The bit about faking being an outcast kind of made me smile though. I don't really think it right to argue much of the rest of that post, though as always understanding is finite. Sorry if i got on your nerves in particular, but this is 4chan / you are Anonymous, and it is hard to see the forest for the trees.
Might i ask your name/age/ethnicity/location ?

Name: Steve-o? (generic?) 2013-01-12 8:49

Not that i don't care if you are an outcast, but it doesn't phase me. There are a few other sayings/proverbs that come to mind, but i won't just blurt them out. I guess i'm a bit overdue for some critical feedback anyway, but really it is the idea's that need the criticism if you could.

Name: Anonymous 2013-01-12 9:04

like this one, for instance. 'A problem shared is a problem halved'. But might i ask, what is a problem borrowed? And yes, its only fair that you question that motive.

Name: Anonymous 2013-01-12 9:53

...hmm, kind of demanding really. Not to mention that i'm being asked/told to fit in by an outcast..? kind of hypocritical isn't it?
Anyway, I was actually going to complain about the prison system, and before that continue with the 'tales from the crypt', but yeah i dunno now... See where this here goes first.
