Ekaitz gave a great talk about trust and the boostrap problem. And did a bit of Q&A on his future plans, along with the what it's like being sponsored to do this sort of work. The video is published: https://www.youtube.com/watch?v=Cj7DyiRqWBk If you'd like to see his slides they're available here: https://ekaitz.elenq.tech/bootstrapGcc16.html Enjoy it!

Somewhere in the chain there is a compiler binary that was created at a previous point in history. The impact on security and trust is that we can't assure ourselves that the platform hasn't been backdoored [0]. Ekaitz and many others have been working on bringing up RISC-V with a full source bootstrap for the last couple of years. In this talk he'll introduce RISC-V, the bootstrap problem and talk about the journey to a full source bootstrap in Guix. > > If you'd like to be notified about **future meetups** you can subscribe to the Wiki or to the Meet-up: > > https://libreplanet.org/wiki/Group:Guix/PatchReviewSessions2024 > > https://www.meetup.com/guix-london/events/303448758/ > > Hope to see you there! > > Steve / Futurile > > [0] https://guix.gnu.org/blog/2019/guix-reduces-bootstrap-seed-by-50/ >
