Plan 9 seems to be disproportionately influential for an OS nobody who's not into systems engineering has ever heard about.

to be fair, it's where UTF-8 debuted

It's mostly coz some people that worked on it went to big companies. Go being one example.

The site seems to be down.

Here ya go http://git.9front.org/plan9front/plan9front/e938acc8ff64a3cb...

Weird to link to the raw troff. One you install 9front or plan 9, you run mk in /sys/doc to render into readable ps/pdf/html documents.

Next up in the blog schedule: "Performance and Scaling in Plan 9"

Already done. https://orib.dev/9hack1.html

Still WIP. We're not yet at a million useful procs.

and /proc

Unfortunately, kids these days seem to be afraid of files. For a hardcore unix fan, curl and wget are useless tools when you can just cat /www/url

The 9p filesystem lives on in a few "modern" places, like within WSL, QEMU, and other places where it's a good bridge between a host OS and container or VM.

Apple added support just in 2019! man mount_9p

Huh, could one use this instead of NFS then?

It's seems nice on a first glance. But how do you set headers and content type for example?

unless i have done it hopelessly wrong, you may be overstating it a little bit by calling it good. virtfs is the good one, not 9p.

virtfs USES 9p.

I think GP meant to say (the extremely confusingly named) virtio-fs, as opposed to virtfs/9pvirtio.

Virtio-fs is independent of 9P and has optional support for using shared memory to greatly increase performance, it also maps better to the permissions and metadata of "modern" filesystems IIRC, not sure if 9pvirtio had this problem but I remember coworkers having permissions problems with the 9P bridge in WSL2 (Plan9's permission system is very simple and doesn't map well to other VFS's)
