Moca Assembler
Yo, and wassup!
I have been quite busy the past few months. I am making my own computer from complete scratch(using the 8086 intel microprocessor, breadboards etc). Along the journey, I learned I had to write my own assembly for it. Furthermore, I figured out not only did I have to make my own assembler, but I had to make it compatible with being able to load memory for the OS I am going to deploy.
My idea is to write a very efficient assembler. Maybe add some of my own syntax even? This is just a little bit of the code(I am not posting all code, for reasons).
I do have a full OS running via Qemu currently, so now it's just down to getting the computer running, getting an assembler going and deploying the OS.6

Official-MocaOSMy Official OS
Moca OS
This is the up-to-date source code of the OS I am creating for the computer I am creating from scratch.
No, I do not know if I will be capable of loading this OS onto actual hardware(in my case probably just have a 6502 chip read data in from the OS output).
The OS runs in VESA mode. So there is a custom font I've made to manipulate the pixels on the screen since VESA video mode doesn't support a built-in font, and VESA video mode is rather more complex due to the fact it allows you to manipulate each pixel individually, which gives us the advantage to make our own font in binary and assign signed bits to a pixel and unsigned bits get ignored(you can see this code in mstdio.h inside the putc function.
Anywho, repl kinda flops when you attempt to run/link the kernel, so if you want go ahead and just copy the source code into your terminal, make sure you have make installed, and just enter make run.
Note: I do not have the terminal part of the OS up and running due to the fact I am attempting to implement my own heap allocator, and I need to also set up the IDT before I can allow user interaction with the heap(the IDT will handle seg faults).39

Alright. I have a question.
This might stump you for a little bit, but here it is:
What if, instead of the universe growing more outwards, it grows
IMayBeMe In your second theory you state:
> What if the big bang was the result of a previous universe collapsing into a black hole, and the result of the big bang was just the leftover particles/gas from the previous universe?
This very much makes sense, but in theory, would be somewhat impossible. To start with, if a universe was to collapse into a black hole, that same black hole would get larger. Now assuming that some particles escaped and created another big bang, wouldn't the new universe also be1 year ago
ch1ck3n Yeah if your theory is correct then there must have been multiple big bangs
Also then there has to be a first big bang in the history of everything that came from nothing, and what did it come from? Honestly, the theory of creationism is much more convincing and possible than a big explosion coming from literally nothing
It is possible that the universe is shrinking and when it shrinks to a super dense black hole and that black hole will go kablooey and then a new universe will begin, and then1 year ago

AlbertoHarvey I've been planning to write an operating system for the 80286 chip and its quirky 16 bit protected mode for a while now. The goal is to have a UNIX-like system without respect to compatibility and without ever escaping to real mode. Explicit goals are:

must support shared memory, memory mapped IO, and dynamic memory allocation in all processes with an unlimited amount of segments per process

Hi. I am here to answer the top questions asked by new developers that also have been very indecisively answers.
Some people say to start with Python
TheDrone7 I kind of agree and disagree with this. I agree on the part that starting off with something like python which has everything built into it can be bad but I also don't think starting off with C is a good idea either because of the boilerplate and the syntax.
I feel like what I started with, is the perfect language to start coding with - BASIC. It has a fairly easy syntax so anyone can get started coding and it only has very little stuff built into it which also promotes being able to solve prob2 years ago

CodeLongAndPros You're dealing with magic values + structs, so it's lowlevel. You have Rust and C, so it must be very low level. You've already done osdev, so I'd say you're reverse-engineering something.2 years ago

xxpertHacker Btw, TS is merely used for the same things that JS is used for. TS is a transpliled language, it's "compiler" is a source-to-source compiler which just emits JS.2 years ago
xxpertHacker TLDR: Imho, TS doesn't carry it's own weight, especially not for small projects.
I can't tell you if you will like it, but based oh how much you agree with or disagree with my logic, it may sway your opinion.
I came from C++ -> JS -> TS, here's my experience and thinking.
Typing disciplines
C++ is statically typed and weakly typed; weak typing can cause bugs every once in a while, but static typing allows one to define strict APIs, and removes the would-be runtime checking code.
JS is dynam2 years ago
Coder100 it is very worth it.
You will be writing much better js code, it prevents you from doing things like this:
let a = null;
function get_key(obj, k) { return obj[k]; }
get_key(a, 'a'); // oh nooo
not only that, but you have access to namespaces, enums, and interfaces! All very common static language features that actually are useful.
Not only that, but you can use es6 modules without having to add type="module" -- everything is all precompiled!
Also autocomplete

DynamicSquid I tried your example on "Creating a 1x1 image", and I saw a small red dot, but then I tried your "How to set a custom file size", and it says it couldn't support the image.
Here's my code:
#include
#include // might not be used in the tutorial
int main()
{
FILE* file = fopen("img.bmp", "wb");
char BMPINFOHEADER[ 2 ] = { 'B', 'M' };
int height = 1;
int width = 2;
int BMP_HEADER[ ] = {
0, 0, // File size, reserved
0x36, 0x28, // Pixel offset, header size

Highwayman I got really confused at the part where you start talking about the header. You say that we can't know the file size at the start, but then you say there is a space to enter the file size in the header...? What did I miss?2 years ago
