My next billion-dollar idea (I have lots of these): GoKrazy but replace Linux with Zircon

@fugueish Chris you probably know why we did not pursue something like this at the time? Maybe not since the discussion predates you joining the team?@zekjur probably heard about this idea several times before. I'm very sympathetic to having only so much free time for OSS project maintenance on the side.My question is: which kernel is being used probably doesn't matter much in the end?

@maruel @zekjur I think that discussion predates me. I think the kernel does matter: Zircon is smaller, designed for privilege reduction, and implemented by people working hard to respond to security problems.

For a long time, we were unhappy about having to spend so much time on each of our various Raspberry Pis, taking care of security updates and other general Linux distribution maintenance.Then, we had a crazy idea: what if we massively reduced the overall system complexity by getting rid of all software we don’t strictly need, and instead built up a minimal system from scratch entirely in Go, a memory safe programming language?https://gokrazy.org/

@fugueish @maruel @zekjur My concern with the microkernel model is that we now have a bunch of highly privileged code (possibly arbitrary memory access) running in user space. We need to learn how to make that secure. I'm sure we can do it, but it's an architecture that we're not used to reasoning about the security properties of.

@ian @fugueish @maruel @zekjur in practical terms, it’s just not going to hit the 25gbps target right now on low power hardware, in fact it doesn’t even have drivers for the relevant nics

@raggi @fugueish @maruel @zekjur Potentially it's easier to build DPDK-style kernel bypass networking since networking's not in the kernel anyway.

@ian @fugueish @maruel @zekjur yeah, it might not be that bad (in relative terms) to actually port dpdk and some of the associated drivers, but still a big time investment

@ian @fugueish @maruel @zekjur the go runtime fork for fuchsia is also in desperate need of love unless it somehow got restaffed after I left

@raggi @fugueish @maruel @zekjur Oh no, that's super deprecated. It happens to be load bearing, but it would take a serious investment to get it in a state to be generally usable.

@raggi @fugueish @maruel @zekjur With the cuts to the FIDL team I can't even pay lip service to Go support. The sooner it gets torn out the sooner it'll stop getting in our way.

@raggi @fugueish @maruel @zekjur Seems to be coming along, but it's hard to get from MVP to production ready for that kind of thing. There's a looooong tail.

@ian @fugueish @maruel @zekjur yeah, although the current one probably covers less of the tail than we might predict, too

@fugueish that sounds like a great way to spend a billion dollars!

@fugueish (gokrazy is so great)
