Times: 17:00 UTC, 18:00 BST (London), 19:00 CEST (Paris), 13:00 EDT (New York) Link to join: https://meet.jit.si/london-guix-meetup The bootstrapping problem is that many OS's can't build themselves from source. 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.
