hmm, this is exactly what TÏ does not want us to do. it's nice, but this will certainly make that ndless gets blocked in the future too..

Oh no... please...


We argued very hard with TI and finally they let us the possibility to downgrade 3.2 to 3.1 and install Ndless...

And you release something like this? Do you want another OS update in august/septembre which will block downgrade to 3.1?

Also, this tool will probably be used by people to cheat. I know cheaters will find a way, but that doesn't mean we should make it easier for them.
I can understand in some ways that you are angry at TI and release it, but I disagree.

This will give TI finally a good reason to block us.

Edit: But of course I respect the work you put in it...

Yeah, the PTT implementation is a complete piece of crap. It's so easy to tamper with it that it isn't even funny.
TI can only be happy that hardly anybody is interested in the Nspire: no Linux port, advanced program loader and advanced graphics library came two years after the initial availability of arbitrary native code execution, and hardly any reverse-engineering on the PTT anti-feature. However, despite the advance warnings, the news that OS 3.2 would block the third generation of Ndless was the last straw that broke the camel's back...

I bet a few of you guys already knew how shitty their PTT was all along, but did not bother to make a move.

AFAICT, while we thought that TI had probably made a huge piece of shit (history told us that they often make huge pieces of shit ^^), proofs of that came only through reverse-engineering, in the last few months.
"Last few months", as in after my warnings to top-level execs not to behave stupidly, and the subsequent silly stance on plugging, no matter the potential consequences (as I outlined to them: making it more likely that the Nspire series goes the way of the PS3 !), the hole used in the third iteration of Ndless.

The fact that such wobbly pieces of infrastructure as the Nspire's PTT are accepted as restrictions for tests shows how incompetent the standardized test regulation authorities, how incompetent and malicious TI is (if they do not know that they make a crappy job, they're incompetent; if they know it, but go forward with the crappy scheme before the regulation authorities, they're malicious)... and for short, how silly and inefficient the whole concept of making a PTT mode is.
Neither making a PTT mode, nor making a closed platform that defaults to trying and prevent (more accurately, trying and failing to prevent) access to native code, are a requirement for getting a calculator allowed in standardized tests...

Hey, what is it with people trying to make compu and myself feel guilty ? TI will keep trying (and failing) to lock stuff down, no matter what. PTT tampering programs could have been released months ago, but people waited until they showed disrespect to us (by closing the hole used by the third iteration of Ndless) to release stuff that TI doesn't want.
The ones which are disrespectful in the first place are TI, not compu or myself !

but please, I am begging you, remove the attachement.

I think that this is a very bad idea, because it would make the (legal !) attachment much more prized, and would end up increasing the distribution of the attachment. Witness what happened with the TI-Z80 & TI-68k signing keys

And we still can try to get the future we want.

Be realistic: in today's and tomorrow's education market, there's no way we can.

The attachment would certainly never had existed if TI had not willfully chosen to keep going on a risky path...

BTW: the previous time I loaded this page, there were 11 downloads of the attachment. Now, there are more than 15...
