KnightOS / Re: KnightOS Transfer Protocol

I might say, that is fairly well thought out.  However, with the flash Chip, are you going to make it where files can be fragmented?  So that way, you don't have to move stuff around a whole lot and writes are faster?

Well under.  It's just under 2MB for calculators with missing RAM, and just over for those with.  However, I refuse to include any code whatsoever that requires use of the entire calculator's memory.  And KFS is already a well thought out format that I will be using.
Excellent.  I look forward to getting the protocol information.  And the code shouldn't use the entire calcs memory.  I can't remember from the specs, but I'm thinking a little over 200 bytes of RAM to use, and then whatever the USB code takes. I'll try and get some test thing working later. I'll still need the Filesystem to do for KOS, but I'll go use one of the earlier file revisions that you've posted or something.

Can we put Xeda's code in a spoiler or something? It's long.

And I'm glad you can get some time to join us SirCmpwn.

Btw, is there any format you would like? Is the FLASH+RAM memory all under 2GB?

So you have the determinant of this matrix... j/k

Okay, so given a function f(x) = N mod X, which is a recursive function. eg, the result becomes the new X.  However, it goes over a little transformation first.  N mod floor(f(x)*N/(N mod f(x))-> X  Given this pattern for X, find N:

Oh, I was expecting critor. He usually does some of the interesting NSpire hacks.  It looks nice apcalc!

That is just... intense. I didn't know you could swap pages that quickly, though.

I kinda did, but the physics for this sand wouldn't be covered in it, as it is just pseudo-physics, a simple algorithm that really has no basis in real fluid dynamics :P
Do you have a link to your physics tutorial? Would you be willing to write one for fluid dynamics?

Casio Calculators / Re: Casio Prizm documentation
« on: January 31, 2011, 07:43:46 am »
So are you going to shotgun your RAM? Be sure to take video of any weird anomaly.  Quick question, though, but do you think if you bricked it, CASO would replace it?

I thought he did already? ???
He might have, and I just missed it.

Math and Science / Re: Formula for getting prime number?
« on: January 30, 2011, 06:07:52 pm »
There is nothing that says it can or cannot be true.  It would kinda fit into the category of P=NP, though. e.g., you can prove S times T equals a number, but finding S and T from that number would be a lot harder.

Math and Science / Re: Factorials
« on: January 30, 2011, 09:02:49 am »
Maybe I should have rephrased a bit differently: The gamma function for positive integers follows the following property: gamma(x)=(x-1)!. Hence gamma(1)=0!=1, for instance.

However, what is gamma(0)? It would equal to (-1)!. But using the factorial recurrence formula would give us 0(-1)!=0!=1. In other words, (-1)! = 1/0. This is bad; hence, (-1)! is not defined, and so is gamma(0).

Most other numbers still have a gamma function attached to it, for example gamma(-1/2), gamma(3+4i), and gamma(1337.42i), but zero and negative numbers when plugged into gamma generate an undefined result, because their respective factorials are undefined as well.

EDIT: Aw darn, sniped
We prefer to say you got ninja'd, but yes. yes you did. ;-)

* King Graphmastur issues a royal decree that Quigibo should do this

I also tried issuing royal decrees that he lose his mind for this community, and add USB support. ;-) But my parliament vetoed me.
