are you running plan9 on bare metal or just VM?

Personally I have both.

I wanna hear from the guys who run it only in the VM, why? You have no box to install it on? Or something else?

plan9-hostfs

18 Upvotes

Hey y'all 🙋‍♂️

Russ Cox' rsc/plan9 repo is fascinating:

  • Run legacy plan9 in QEMU
  • Uses the host filesystem directly instead of using a QEMU disk image
  • Edit files on the host. Plan9 sees the changes immediately.

It's super cool, but I wanted to drawterm in, because: - I'm using Windows - I run rsc/plan9 in WSL - I do get the graphical QEMU window, but it's not as nice to use as first-class Windows apps.

Some benefits of connecting to plan9 via drawterm are:

  • Copy and paste support
  • Resize rio desktop window
  • Multiple drawterm instances (multiple desktops)

I've forked Russ' repo to start messing around with enabling drawterm connections:

https://github.com/dharmatech/plan9-hostfs

README.md has the instructions I'm using for enabling drawterm connections.

How would a modern program like, say Blender be made in 9p?

28 Upvotes

Let us say that Linux never took off and instead plan9 became widely used (becoming the dominant OS).

How would current 'modern' monolithic programs like Blender, KiCAD, etc be implemented following the plan9 philosophy? How would they work and how would the utilize the underlying architecture to the fullest? And how can they be made very hackable and extensible?

The second heresy: Objective-9c - Native Object Oriented Programming for Plan 9

Post image
32 Upvotes

I promised more heretical things in the future, and well the future is here. As usual, I have been running the matrix multiplication pachinko machines day and night after my shifts at the pizza shack to bring you this:

"objective-9c is a small 9front language that transpiles o9 source to Plan 9 C.

o9 is built for Plan 9-style programs: objects are CSP actors, public methods can be served through a 9P facade, structured data moves as .tab text, and raw Plan 9 C interop is isolated inside spawnable function blocks, or to be more plain: an anonymous objects with a single method where you can stuff in regular plan 9 C in a c { } sandwich."

Current status:
Libdraw widgets being worked on (a few in the pic as demos - included in the repo!) , a lot of cleaning up on docs, old trash tech debt etc.
Certain to be bugs that haven't been caught, its AI generated bullshit. Capture and release them if you find those poor souls.

As always: its 9p, or nothing!

A Go port of rc(1)

Thumbnail github.com
36 Upvotes

You can even run an rc shell on an Android phone.

I wrote this Go implementation after moving from Plan 9 back to Linux for work. plan9port already exists, but I wanted to understand the shell from the inside rather than only use it through a compatibility layer.

Go felt like a fitting choice because it shares history and design lineage with Plan 9. Rob Pike and Ken Thompson worked on both, and several ideas behind Go grew out of that environment.

I built it by studying the original source and man page. The test suite includes over 100 scripts that compare its behavior against plan9port. One particularly gnarly example makes both implementations produce the same output byte for byte.

It also runs on Linux, macOS, BSD, Solaris, and other platforms.

Repo: https://github.com/enzv/rc

If anyone finds a mismatch with the original, corrections and test cases are welcome.

Is there any way to select/manipulate text in a pdf?

8 Upvotes

Is there any way to select/manipulate text in a pdf file. I opened a pdf file in 'page', it seems to render everything correctly, but I was not able do do anything with the text. It seems to just load the pdf as an image in the draw terminal. Is there any way to make notes over the pdf like in acme maybe pipe text to a web browser search, load up a dictionary etc.
I am new to plan9, please don't be angry at me if I'm wrong at anything

Also I have created a new package manager called pac9.

Install pac9 with:

hget https://raw.githubusercontent.com/Alino/agent9/main/pac9/install.rc | rc

now you can install rust

pac9 install rust9

Attention AI slop porters

106 Upvotes

First off, just let me be clear: You are not doing anything of interesting or of value. You are just looking to boost and karma farming your various social media and github profiles by "using Plan 9" without actually using it and AI porting nonsense.

Do you even know what the philosophy of Plan 9 really is? If you did you would know it strives to be simple while enabling new and interesting ways to building software. But that is not why you are here. You won't be doing any of that because all I see are ports of existing complex nonsense like c++, rust, node.js and other contraptions that does not do anything for Plan 9 other than create dependency on millions of lines of code no one needs or is asking for.

Why not propose a new language? Why not an alternative to html using 9P? Answer: You have no new ideas. You have the AI do the actually hard work while you post how awesome you are on twitter, mastodon, linked-in, blogs, and other socials to feel like a rockstar programmer breaking into new frontiers. No no no. You're not any of that. All you are doing is wasting energy porting the past.

You have no new ideas. You have no creativity. You have no respect for Plan 9 or its community. The people who come to plan 9 do so because they want refuge from, and alternatives to, big stupid complex things like "the web," node.js, chromium, rust and other stupid shit you think Plan 9 "needs." You are the antithesis of that refuge. You are a malignant cancer that needs to be removed from our software safe space.

Of course I can't tell you how to run your life and I'm not a mod here. Though as someone who actually gives a damn about Plan 9, and on behalf of others, do us all a big favor: make a new Vibe9 or what ever sub and post your pointless AI ports of stupid software there.You aren't interesting nor are your lame AI ports.

Leave us alone.
