I finally joined the mailing list
Two questions about potential contributions:
Out of personal interest I have created/implemented the Fortuna (CS)PRNG [1,2] (still WIP + needs AES256). Contrary to the Tiny Mersenne Twister, this PRNG is bigger and slower, but more secure. I believe native/boards with crypto accelerators could benefit.
I ported U8glib  and got it working with a SPI LCD: https://www.youtube.com/watch?v=bG5_EwFTiDc. I already showed this on IRC, but wanted to share this with the rest that hasn’t seen it yet. It can also emulate a display on stdout.
Would both be valuable contributions, or can I better wait for the (hopefully upcoming) ‘RIOT package manager’ ?
Kind regards, Bas Stottelaar
