TI-BASIC / Re: Secure (Ish) Cipher
« on: December 03, 2010, 09:46:54 am »
How long does a 16 bit key takes to get factored on-calc? What about a recent computer?
...okay, so it can be human-factored in under 5 minutes. It was a proof of concept XD

Topic title changed. To be fair, when I said "secure" I meant "your crypto nerd friends will go at it for about a week," rather than "1024-bit RSA suitable for issues of national security."

Though I did make 16-bit RSA once. :)

TI-BASIC / Secure (Ish) Cipher
« on: December 01, 2010, 06:41:50 pm »
A simple example program that converts text to ciphertext and back again. Because it uses the rand seed, it's super-secure: unless someone knows it was coded on a calc, they're not getting it decoded.

Supports A-Z and spaces. Key can be any number.

Optimizations welcome.

Axe Parser
Delta 0.4.6

Static data can be stored to variable pointer
Thanks for bringing this to my attention: this helps a lot for MFQT

EDIT: formatting fail

Wow. This is really hard.

Now I'm going to fail all my classes. :)

Neat! I'd love to have that around. Good luck Xeda!

I might give the audio-from-a-USB-drive idea a try.  I guess I need to learn how the MSD protocol works, though. :P

(Does anybody know where to find a 2.5mm-to-3.5mm adapter that fits in an 84+'s link port?)

you can buy one from radio shack for $6.
Just make sure you have a sander and a steady hand, so you can remove some plastic from it.  As it is a tiny bit to big.

Note: NOT the plastic bands on the jack.
really? ???
With my 83+ I did not need to modify my adapter at all to fit it in. It's a bit loose, though...
I ran into this problem too. Happily, the Pulse smartpen comes with a flawless set of 2.5mm headphones.

If that is the 16 bit OR operation, shouldn't you be incrementing A by 2 every cycle since you need to increment 2 bytes?

No. Because of how loading values into 2-byte pointers works, it actually returns the address of the pointer plus 1.
Thanks for the clarification.

...dunno. not my code. prolly tho.

Lol scout. If I ever need to get out of the country you'll be the first person I call.
Not me? D:
Oh right, Canada is another country too...come to think of it, that's a little bit closer than Portugal. Hmm. I'll have to think this one over. :)

If you want a really extreme optimization for or-ing the screen, here it is.  It will be noticeably faster and smaller:
Code: [Select]
.# represents the 16-bit or operation
L₆→A
While -768-L₆
{A}ʳ#{A+L₃-L₆}ʳ→{A}ʳ+1→A
End
This seems like it should work. And apparently it runs >40x/second, so it's plenty fast. I've already implemented nondestructive sprites (with a noticeable speed increase attached,) so noncolliding text and backgrounds should come soon.

as rendering a $400 calculator unable to run tetris is apparently a common fate
As first posts go, this one is pretty awesome.
Welcome to the Omni forums, hope you enjoy your stay.

Why didn't you go to Portugal and warn ScoutDavid that you couldn't come and made him very sad?
I had to reread this a couple times to understand it. Lol scout. If I ever need to get out of the country you'll be the first person I call.

tonight i ordered this shirt
I want one.

PROJECT RELATED STUFF:
anyone know how to OR buffers? I've looked through the command list and there's no hardcoded way evidently...axe is hard. how are you guys all so good at this...

Some fun Q&A for you guys.

Whoa! It's JustCause! Where were you for the past few days?
Sadly, I can only get on Omni during school hours. Thanksgiving vacation meant that I was cut off for a few days.

Did your dad kill you?
No. Actually, we've reconciled (somewhat). Maybe his strict parenting style has something to do with the fact that he's a self-made man who grew up in inner Chicago with a Republican Catholic cop for a father, then went into the military despite the exact same bone defect that I had, used it to pay for college, and recently made it through three grueling years of law school. He doesn't have much patience for people with (what he sees as) lacking work ethic: of course, he holds people to the same standards he holds himself, which means almost no one measures up. (He's also not too bad at NFS Hot Pursuit.)
All jokes aside, he's a good man and I respect him, despite his temper. I really appreciate all the support you guys have offered up, and I do have the DCFS number memorized if I ever need to use it again. (That's right, it has come up before.)

So do you have an update for us?
...no.

Did you do any coding over break?
...no.

Are you giving up the project?
NO! I've simply decided to stick with things I know I can code for right now, which means I'll be making the switch over the next couple days to a different buffer system: I'll be ORing both buffers onto the screen and using nondestructive sprites like Builderboy suggested, in order to allow for non-colliding text and backgrounds. I'll also be adding a variety of static features with simple collision detection: features like, to use Portal 2 examples, Aerial Faith Plates and Excursion Funnels.

Where's that upload rush you promised?
Standard procedure. All updates must always take 3-5 days longer than expected to be delivered.

Would you, by any chance, happen to have bought an epic Mario hoodie yesterday?
Yes! How did you know?

Last post until Monday.
Just found out something neat: MAZE1 generates a 20x20 maze in less than a second if you leave out the DispGraph in the main loop.
