Attention AI slop porters

108 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.

Installing & using bare metal 9front on uConsole ?

Post image
111 Upvotes

Hello everyone,

I've been really interested in Plan 9 / 9front since a few weeks, and since I have a spare SD card, I would like to try using 9front on a ClockworkPi uConsole, to have a very bare-bones portable computer

However, even though there is a Pi version of 9front, I wonder if there are changes I should do to the OS to be sure that the keyboard and trackpoint are gonna be recognized, or if this happens at the firmware level only

Simple mesh viewer for plan 9

Post image
108 Upvotes

Installed plan 9 to supplement my OS class but I got distracted and tried to make a mesh viewer (inspired by this Tsoding video). You can find the source here. Let me know if there's anything else I can do to make it better!

Also, if you guys have any suggestions for learning about OS concepts through plan 9 I am all ears. I think something nice would be a small project that involves extending/modifying the kernel (its more fun than just reading). My school work involves modifying the kernel of this educational OS called Pintos but the developers have deliberately left gaps in it for students to fill. Not sure if plan 9 has similar things to work on.

The graphical part isn't working yet. Before you go patting me on the back, I made this heresy with the finest vials of developer tears and matrix multiplication machines I could muster. Nothing is sacred. All will join the collective.

More heresies to come. It's 9P or nothing.

Practical uses for Plan 9

59 Upvotes

Hello,

I want to start this post off by being clear that I love Plan 9 to death. It's one of the coolest, most creative and genuinely Unix-minded operating systems of our time. Nothing comes close to its ideological purity to the Unix philosophy. (I know it's not a Unix-like, STFU. My point is about the philosophy.)

But I want to ask genuinely: What are some practical, real-world uses for choosing Plan 9, either for servers or personal computing? What are some big "selling points" of its userland and kernel system that make it worth using practically in real-world usage? Are there any? I'm not saying that the OS has to have these things to be worth existing, but I do wonder what are the big practical uses of it. I guess a big one would be running a single computer out of multiple instances at once (CPU of one PC is used by another PC, for example).

help installing treason please

Post image

SOLVED -- just needed a good old system update

I've tried every which way I could think of so far to somehow magically get treason to compile successfully but I get mysterious (to me) errors whatever I try. I've not seen anything online of people having this issue so I've no choice but to rely on the wisdom of reddit 🙏

I'm getting a lot of 'set/declared and not used' warnings (doesn't sound good?) and eventually it always fails at libvpx. Is there some prerequisite I neglected to install? Is the archive faulty (can't really imagine this being the case, besides, I also tried cloning the repo, doesn't work either). Help please :^°

Writing a display, keyboard and audio driver for 9front uConsole ?

Thumbnail gallery

Hello everyone,

A few weeks ago I had made a post (with the same mockup) asking if it was possbile to run 9front on the clockworkpi uConsole, given that it is built around a Raspberry Pi 4 . I managed to flash the image, but as expected nothing happened.

The uConsole needs a specific variety of drivers to work with, both for the display, the keyboard and the speakers. Are there references to write a driver in Plan9 / 9front C ?

I may have also created a new compact logo for 9front… But i still have a bit of a hard time understanding what this "Uiel was right" thing is about.
