Programming, couple questions

[debrouxl]

Yup, that's the cause of a number of people (among which myself, clearly) thinking that the Prime was based on WinCE, even if we saw at the same time that the user-visible part of the Prime firmware is an ELF file, while ELF is not WinCE's favorite format.

Out of the box, the Prime provides no access to native code. critor and I scratched an itch and showed months ago that modified firmware upgrades (and as such, certainly, arbitrary firmware upgrades) were possible on the Prime, see some sub-pages of http://tiplanet.org/hpwiki/index.php?title=HP_Prime
If someone finds enough time, the Prime would become the second calculator, after the TI-Nspire, for which a Linux port is available (and for best results, based on Device Tree and integrated into mainline Linux, like the Nspire port).
