<oriansj>pabs3: I like the idea; it is a logical extension of the idea of using glass transistors which enable optical inspection.

<pabs3>not suitable for every malicious change (like that doping paper some time ago) but a useful technique yeah

<Foxboron>Generally refrain from pasting code into IRC. It spams the channel

<Guest85>sorry

<oriansj>Guest85: you can use sites like paste.debian.net and just share those links (it also provides syntax highlighting)

<stikonas>newer qemu versions seems to be randomly segfaulting with stage0-posix-riscv64 and aarch64...

<stikonas>riscv32 seems to work though

<oriansj>hmm, either qemu regression or we need to improve compliance with some standard I don't know about yet.

<matrix_bridge><Andrius Štikonas> Could again be some brk issue, qemu is not that good with brk
