Can you give me the source for that, I'd like to learn it.

TI-Basic will be supported, though.
What do you mean? I thought you were only talking about assembly with compat8x. Are you saying KOS will support basic?

I am utterly ignorant of the finer nature of Assembly mechanisms and terminology, and because I cannot tell from context, I'll ask a noobish question:
Will Compat8x handle TI-Basic programs or Assembly programs? (or both?)
Assembly programs only, I'm afraid. EDIT: apparently, I might be wrong. See next post.

Well, that's amazing. I'm working on my own secret project about this... *evil laugh*
Good luck Sir. The copying twice things would probably be bad for huge programs. I bet you could get around that in some way.

Yeah, I liked the old version where it had our names as links in omnomIRC.

So theoretically, one could pirate applications as ASM programs 
By the way, couldn't one simply change the application header to make an application valid without needing a certificate (therefore making it free)?
I don't think so. I know that there is a patch that makes all apps seem valid when receiving, though.

Not a clue.

We would need new a hosting provider, or set up our own server.

True. And wikidot isn't like a wiki, becahse you have much more freedom.

A compatability layer (kinda like Wine) is very feasible. I've been playing with ways to do this with TIOS<->KOS compatability.
Well, with what I am thinking, you would have to re-write another kernel, or I would write it. But, it would allow any OS that worked with the KnightKernel to work with this.

Cool to hear, that would be awesome 
It would suck if the community was split, otherwise. Fewer people would play certain programs because they would use an OS that won't run them. Kinda like Linux vs M$ a few years ago.
Yeah, I know what you mean there. The idea is to make OSes have the same core (Much like KOS does). With the delay of KOS, I'm wondering if it would be possible to... Oh, that gives me a great idea, dj!

They'll both show up on OmnomIRC and raise post count. Random Discussion section != Randomness sub-section
Oh, okay, that's good to know. Thanks, and sorry for being part of the reason you had to take a break. Here's to a great 2011, though!

Well, to compute an OS signature, you take the MD5 hash of the complete OS (the OS header followed by each of the pages, in the order they're listed in the 8xu file), and sign that number using RSA, with a validation exponent of 17 decimal (if x is the MD5 hash, you want to find s such that s17 ≡ x mod n.)
The signature, then, consists of the bytes 02 0D, followed by the length of s (in bytes), followed by the bytes of s in little-endian order (least significant first.) Look at the OS files from TI to see how it's stored in the 8xu file.
the "=" in " s17 ≡ x mod n" is supposed to be congruence, correct?

Don't sell yourself short. The fact that you did that in the first place is awesome as well. It's projects like these that makes the people who developed Ndless and Nleash happy.

There is a field in the app header that if it's not signed, it's considered a temporary or trial app, which gets deleted after 16 (or maybe 18) times.
A small quibble: it's not the app header or signature that's the issue; there's a separate field (stored on the certificate page) that indicates whether it's a limited-trial app. That field gets set when you install an app by normal means (over the link port), but not when it's created by Axe.
Signing the application is a tangential issue: it needs to be signed in order to be transferred to another calculator.
Oh yes, that's right. I remember now, because I was appalled (sp?) at how often the calcs actually messed with the certificate.
