No, no :P
But I wouldn't like it to be completely viewable to the outside world (especially from TI's people) with what's going to happen soon-ish between them and  me+other people...

the other videos I posted about hacking the memory and the TI.Image format, I just made them private for now (just as a precaution), but this one is ok.

(can't tell more :P)

Oh ok. I hope you aren't hired by them to work for them, forcing you to end every contribution you did for the community, though O.O

Ah phew... at least I'm glad you're not going to contribute to further OS 2.71MP protections. :P

By the way, iirc the second image is not an actual screenshot of the glitch, just an idea of what it looks like.
Yeah I know. He sadly did not have a camera when the glitch happened. It was a rare bug.

the glitch isn't that rare, its just that it lasts for about 1-3 secs, I think i may have something to do with updating the screen?

Minor setback due to code messing up.  On hold for Contest.

Hmm, it goes away after a few seconds? Sounds like it could definitely be a data cache issue as I thought. After more code is run, which will be a small amount since not much is happening, different data will fill the cache and the graphics data will be dumped into the actual memory and be displayed by the driver.

And here we go again.  People at the google nspire site are having trouble updateing their os to the latest one.  Ref: http://groups.google.com/group/tinspire/browse_thread/thread/73244e7d5467b928?pli=1
Is it just me or is it impossible for ti to do anything without f-ing it up?

Could the screen updates itself by chunks, but sometimes fails to update some parts due to sending data to the LCD memory too fast?

The strange thing is, that the TI-nspire CAS Teacher Software does not crash when performing " "+" ", so I think it's some kind of low-level problem.. Most of the things that crashed the nspires also crashed the simulator. ("The Application 'TI-Nspire CAS Teacher Software' has unexpectedly quit")
