Hi Guix and bootstrappable! If any of you is considering starting a PhD, there is one position at KTH (Sweden). The topic is on bootstrapping and DDC (double divers compilation), and it's all motivated by the Trusting Trust talk by Ken Thompson, which is very famous in our community I think :)
Please see the following link for details and application: https://softwarediversity.eu/hardening-the-software-supply-chain-with-multi-compilers/ Note that you won't work with me, I'm only relaying what I think is a great opportunity if you're in that stage in your studies. It's really awesome to see something like that, so close to some of our favorite topics :)
