No freaking way! This is so awesome, I don't even have words for it! Really hope this finishes. If only I could help in some way Sad

Maybe with ndless USB support we can have a hook up a hard/flashdrive and use that as filesystem?

With a working Linux port, we won't need Ndless' USB support: Linux will be running on bare metal Wink
(assuming the USB controller has a Linux driver, otherwise it will have to be made for this Linux port - in which case, the work on USB support for Ndless would prove useful for reverse-engineering and reimplementing)

Well, with 'all due respect for you sir', i wouldn't rely on that. Impossible is nothing remember?

Well, he can always try to use a ram disk to install the initial file system: http://lwn.net/Articles/210046/  and more http://www.ibm.com/developerworks/linux/library/l-initrd/index.html
Good luck. Wink

It's unlikely to be possible to 2048-bit RSA keys before two or three decades (if it ever becomes practical), i.e. a complete eternity in the field of computing Wink
Even factoring RSA-1024 is currently pretty much out of the question, though the leading researchers of the field believed in 2009 (when they factored RSA-768) that factoring RSA-1024 could be done by 2020 (but probably no sooner than 2015).

That's a pretty good idea, i'd say. Maybe in the end TI will give up on their OS and just install an open-source os, like Google (well rebranded mind you), and still make a lot of money. Who knows what the future has in store for us? Wink

Even back when they made open-minded calculators (which was the case when I started programming said calculators), they didn't provide the RSA private keys for the OS. Nowadays, where they think that not giving such keys protects their assets for standardized testing, why on earth would they provide the private keys ?
Don't set your hopes anywhere with TI's openness Wink

We're off-topic, though Wink

If this port gets successful (and I have a feeling it will), it will change the entire Nspire scene.

sorry about that, but the youtube embedding feature is really picky. you have to use the link obtainable by pressing the share button and selecting long link or it doesn't recognise it.
and that's pretty fantastic =D
