AvocadOS

If you really wanted, you could totally write all the JS stuff in a different programming language that transpiles down to Javascript (e.g. Typescript, or even something like Go or Scala)

Was gonna see how linux was written but encountered this

Found something :D

Useful resource #1: OSDev wiki

TIL there's an OS that fits on a flopy disk

Mars Ultor

@Maltysen @Downgoat @ZachGates ping to make sure you remember

es1024

9:54 AM

@MarsUltor there was also an operating system in 3,555 bytes of C with lots of whitespace written for 17th international obfuscated c contest (more details)

Mars Ultor

12:28 PM

@Everyone remember to make it a microkernel

Also try to make it small if it's possible. That way it will be very fast and customizable.

PhiNotPi

I've always wanted to make an OS.

Downgoat

2:59 PM

@PhiNotPi Should I then add you to the jQuery OS team?

PhiNotPi

Sure

How much have you guys already done? Almost nothing?

Downgoat

@PhiNotPi We've started on the bootloader but none of us know asm, so we're all learning along the way.

@PhiNotPi invited

PhiNotPi

Have you seen this article on the OSDev wiki:? wiki.osdev.org/C%2B%2B_Bare_Bones

Downgoat

Right now, I'm reading this one: mikeos.sourceforge.net/write-your-own-os.html

PhiNotPi

3:17 PM

Is it even possible to compile JS to C or anything like that?

Downgoat

there is a C++ implementation of JavaScript so yes

PhiNotPi

I assume you are talking about duktape.org

Downgoat

Spidermonkey is written in C/c++

Mars Ultor

Aren't all js interpreters written in c/c++?

Well, almost

Downgoat

yeah

well, Rhino is written in Java

Mars Ultor

3:33 PM

Recompiling an existing interpreter to x86 won't work?

Btw, read the getting started section on osdev

/me hates using a windows phone

Also, apparently microkernels > hybrid > monolithic, just nobody's been bothered to create one that performs well

PhiNotPi

So, I guess the steps in loading the OS would look something like... boot loader calls a C program, which then has to implement all of the fancy functionality that the JS interpreter requires, and then we load up the interpreter, which we then feed the rest of the OS source?

Mars Ultor

And scroll up, there's some stuff about small OSes

@PhiNotPi any binary program will do, but we're probably using c

@PhiNotPi not sure if we can just recompile V8/spidermonkey

I'd honestly be really surprised if jQuery OS actually gets finished though

I think it should be renamed <something>.js because of XKCD. and node.js/os.js

@PhiNotPi fancy functionality?

Downgoat

jquery.jsOS

Mars Ultor

@Downgoat but that doesn't end in .js :(

Downgoat

jquery.jsOS.js

Mars Ultor

3:48 PM

What

PhiNotPi

@MarsUltor I'm basing that assumption off of this...

Mars Ultor

Maybe jqueryos.js?

PhiNotPi

You should now
	# realize one of the profound truths about kernel mode: There is nothing
	# there unless you provide it yourself. There is no printf function. There
	# is no <stdio.h> header. If you want a function, you will have to code it
	# yourself. And that is one of the best things about kernel development:
	# you get to make the entire system yourself.

Mars Ultor

Avocad.js?

PhiNotPi

from the OSDev bare bones article

Downgoat

3:49 PM

@PhiNotPi whaaaaat

is there still argc and argv?

Mars Ultor

@Downgoat c for OSes

PhiNotPi

My assumption is that, whatever is in the JS interpreter, it probably assumes a lot of OS functionality that we will have to provide it.

Downgoat

do I have to do asm to add to the output register then?

Mars Ultor

@Downgoat ?

Downgoat

there is no stdio so I don't know how to do input/output

PhiNotPi

3:51 PM

If we want to print to screen, we will have to write directly to video memory: wiki.osdev.org/Printing_To_Screen

Downgoat

oh my gosh

Mars Ultor

@Downgoat scroll up, apparently it's possible in 3kb

Someone made an 8086 emulator in 8086 bytes as well IIRC

Downgoat

people are crazy, but so are we

Mars Ultor

@Downgoat also, somewhere up there I linked to a small OS with nice graphics that fits in a floppy disk

Maltysen

@Downgoat interrupes

Mars Ultor

3:56 PM

Also, since I hope we're gonna make it a microkernel, it should mean much of the stuff is not run by the kernel

Downgoat

hm, where is the stdio source code...

Easterly Irk

4:14 PM

okai morning

did you go all through the night?

Downgoat

@EasterlyIrk monking

I'm writing a display thing right now...

Easterly Irk

cool

What can I help with?

Downgoat

you can help write some IO stuff

or really anything

the bootloader has been barely started

Easterly Irk

Are we going to make our own or use a premade one?

Downgoat

we're going to make our own

we're going to use spidermonkey's JS engine though

Easterly Irk

4:19 PM

okai

Mars Ultor

/me has yet to sleep

Easterly Irk

rofl

What time is it for you @MarsUltor?

Mars Ultor

2am

Downgoat

O_o

Easterly Irk

niiiiiiiiice

9:20am here.

Mars Ultor

4:23 PM

I usually read webcomics from around 12 to 3, because I'm supposed to be asleep but I don't really feel like sleeping, and I can do hardly anything on my phone

Easterly Irk

okai

You still have to deal with parents?

Has anyone here killed the Doom final boss on nightmare mode?

According to the site, that is harder than creating an os.

Mars Ultor

@EasterlyIrk ?

Easterly Irk

Are you a highschooler, college student, or adult?

Mars Ultor

@EasterlyIrk highschooler

Easterly Irk

okai

same

Mars Ultor

4:27 PM

Apparently a lot of people here seen to be highschoolers

Easterly Irk

Technically I am a middle schooler, but eh.

same thing

Mars Ultor

More specifically, 15-16

Easterly Irk

@MarsUltor A lot yeah

Mars Ultor

@EasterlyIrk Wait what

Easterly Irk

I think the majority is 20-25.

@MarsUltor I am a middle schooler.

Are you not american?

Mars Ultor

4:28 PM

@EasterlyIrk what grade?

Easterly Irk

7th.

Mars Ultor

/me is too lazy to bring up SE rules

Btw, Australian

Easterly Irk

I am 13, so I am fine here.

@MarsUltor oh yeah

YOu made me think that Downgoat was australian when you were Upgoat.

That was really confusing.

Mars Ultor

@EasterlyIrk just no personal details allowed or something I think

Easterly Irk

eh

yeah, that's right.

Minibits has an 'account' created with permission from his dad, Geobits.

Mars Ultor

4:32 PM

@EasterlyIrk wait, minibits has an account?

yep

Link?

brb finding

7 4

Minibits

1 1

On PPCG and Arqade.

I think he is 7-8.

Downgoat

I started on the video memory

if anyone has a VM can you compile and test the OS?

Easterly Irk

brb getting VM

Mars Ultor

4:36 PM

BTW, I kinda know how Americans are different, just I wasn't aware there were any <15 year olds here

@EasterlyIrk get virtualbox

Easterly Irk

;)

okai

Mars Ultor

Also might need NASM

Easterly Irk

got that

brew install nasm was ran last night.

Mars Ultor

7 rep?

Easterly Irk

2 answer up, 2 answer down.

Mars Ultor

4:38 PM

s/ran/run/

Easterly Irk

screw grammar

He answered something to a guy using cheats, which got him into the original problem.

Downgoat

do we want to use BIOS for our I/O or make our own?

Easterly Irk

Start with BIOS.

Downgoat

and do we want graphic support or just plain text?

Easterly Irk

Plain text.

Figlet + Picascii.

:)

Downgoat

4:41 PM

I'll do GUI, that we we can admire the jquery in full HD

Easterly Irk

eh

idc

Also, how can I boot AvocadOS into VirtualBOx?

Downgoat

no idea

did you built it?

I think you have ot modify the master boot record

Easterly Irk

:(

I think it needs a .iso.

Mars Ultor

Idk

I can do it tomorrow

Also, will this have a c9?

Easterly Irk

idk

brb making

Mars Ultor

4:45 PM

Booting avocados is a bad idea

Easterly Irk

yeah

but not AvocadOS!

It appears you found your example for creating a bootable ISO image from this StackOverflow Answer. Unfortunately you picked an accepted answer that is incorrect in many ways. Pretend you never saw that answer. On most Linux distros either a program called genisoimage or mkisofs exists. These da...
