This is similar to what we did for my 400-level computer architecture class. Only the system we were writing it for was based on a Motorola 68K chip. We had to write all the low-level hardware drivers and a simple OS kernel that tied it all together. The final involved booting it up and loading a program from a floppy disc that the professor gave us (yeah, we implemented a floppy controller driver). The program utilized every feature we had implemented to date to run a very simple (ascii) version of Tetris.

You are a brilliant and consistent man, I thought of creating a simple OS myself back in days when I was obsessed with writing things from scratch but couldn't do it because it is so much work and requires you to understand a whole lot than a normal programmer understands about computers. Your video gives the gist of what it needs to even write a very simple bootable software. Love your work man and thanks for sharing the Github code as it may help someone who is as cool as you.
When I started coding I thought using libaries was some sort of cheating, as I basically just ran someone else's program which I couldn't write myself. This guy took that thought to a whole nother level
even the people who wrote the libraries were cheating ... since they used a high level programming language ... only the people who wrote C didnt cheat :)
As someone who has only really used high level languages this is incredibly fascinating, all your videos are great and I hope the RUclips algorithm would favour your channel more. Awesome content
This project is so needlessly hard and complicated but at the same time so beautiful to watch. Must have felt _so_ satisfying to see through this project after all the pain that went into making it. This I aspire to become as a junior dev.
I am truly impressed by this. I'm currently learning more and more code as the days go by (at least it feels that way). And seeing something like this really does make me motivated to keep pushing. I guess I gotta start doing some leetcode first though, to at least get those concepts in. (Mainly been doing webdev until now, so backend is kind of a new field for me)
One more thing you can add is the Tetris bag randomizer where the seven unique pieces are shuffled and outputted as a group repeatedly. Three T pieces coming out of the first four was surprising. awesome video
As someone with no assembly knowledge, this whole video was a bizarre combination of surreal, confusing and inspiring. I kinda wanna learn assembly now.
as far as my understanding goes there isnt really any practical purpose to use it in this day and age, the only real reason to use it is for hobbyist things
To be fair C++ is pretty hard to use, don't feel bad. And you too can build anything from the ground up. Computer science is like playing legos. You learn easy stuff and build them on top of one another to make something complex. Over time you can do some impressive stuff as well! What matters is being too angry to give up.

“I don’t think Tim Apple would like me booting this on his hardware.” That’s code for, “I have no idea how to get a Mac to boot something other than MacOS.”
Back in the PowerPC days, running anything besides Mac OS is complicated. Now with Intel, it's way easier if you want to run a recent Windows version with Boot Camp. Anything besides that might become challenging, too. But soon, with Apple Silicon, I think it'll be straight impossible to run anything else than macOS.
Beautiful. I wrote an OS for fun too (back in the early 2000s). It had a bootloader, never left Real Mode, and could display a command prompt, and that was it! I was incredibly happy when I put the image onto a 3.5" floppy and it actually booted on my machine (modern machines with UEFI instead of a BIOS would have been much harder). Then I proceeded to never look at it again and question my life choices.
Dude this guy made an operating system in a month and I can't even figure out data-orineted design in that time. Where did you learn to program? I'm mega jelly about your skills at all things programming.

I think he just has a lot of free time on his hands. You see it's not overly difficult to develop an os, it's mainly very time consuming and it's easy to write bugs. The theory is rather easy.

you will need some knowledge of computer architecture, core concepts of operating systems and some skill in assembly. A few books that can help you with that: - Programming From The Ground Up by Jonathan Bartlett: teaches you x86 assembly, a bit of computer architecture and other things - Operating System Concepts by Avi Silberschatz, Greg Gagne, and Peter Baer Galvin: it's a great introduction to operating systems, it teaches you how the operating system interfaces with hardware, how the operating system gives support to the user space programs etc. It will teach you much more than it's needed to built what's on the video tho. - manuals on the hardware you're trying to write software to - for writing drivers there are a lot of books about drivers on linux, they might give you a good idea how to do it
When i implemented a bare-metal Tetris for an ARMv7 i used a list of coordinate offsets from the center of the tetris block instead of a matrix containing bits - that makes rotation much easier because you can just use rotation matrices
From my very limited experience from writing memory manager for Nova (had to do it for uni) and some assembly (also for.uni) I admire how persistent you had to be to one man this. Had to take so much effort. Very cool

Mind if I ask what you are working on. I have been obsessed with Arbitrary code execution on retro videogames. And I am currently working on a sort of cheating library of my own. In similar vein to cheat engine.
If I can give you advice: try sleeping sometimes. It can dramatically improve the quality of your written code, which reduces the amount of bugs you accidentally introduce.
@@tentative_flora2690 Yeah, I wasn't doing anything like that, I muddled up some ROTATION CODE. Basically, when calculating the rotation of an object based off of the normal of a face, I had accidentally set a mess of trigonometric functions that caused the rotation to get confused. NGL ACE, especially in older games, is super cool :)
Okay, I'll admit it. I clicked into this video going "an operating system? Psh, yeah right. I bet you're just gonna make tetris in javascript or something." You coherently made an outstanding product with quality code design. My applause to you
I learnt Java at uni last year as part of a softdev conversion course but have never looked at C before. I'm amazed how much I understand without ever having written or studied lower level languages. Thanks jdh.
Personally I do with C++ and Rust and use some high quality open source libraries like GFX-HAL or BGFX for cross platform rendering, PhysX for physics, ImGui for GUI, and I’ve even integrated a LISP interpreter for scripting my game, However I know that it is possible to script the game with C++ and Rust by using a WebAssembly interpreter and achieve higher performance, However I still haven’t done that.
Github code repo is gone, just checked and thanks for the video. I can't draw with a pencil, let alone with the code. Your dedication and passion can't be matched. I never ever thought that I'd see an OS, from scratch, running an enterprise workload called "Tetris"
It's very well done and I know this is a little old now but you forgot one of the core mechanics of Tetris, tera groups the game generates a group of all possible pieces and then pushes them in the random order then generates a new one you never get more than 2 of the same tetra in a row and I saw multiple times of you getting the same piece 3+ times in a row.
it's a bummer the company behind tetris actually dmca-ed the fuck out of the github repository. i mean they were in their right to do so, but it's also a bit sad that such a big company strikes an educational piece of code like yours.

This is similar to what we did for my 400-level computer architecture class. Only the system we were writing it for was based on a Motorola 68K chip. We had to write all the low-level hardware drivers and a simple OS kernel that tied it all together. The final involved booting it up and loading a program from a floppy disc that the professor gave us (yeah, we implemented a floppy controller driver). The program utilized every feature we had implemented to date to run a very simple (ascii) version of Tetris.

You are a brilliant and consistent man, I thought of creating a simple OS myself back in days when I was obsessed with writing things from scratch but couldn't do it because it is so much work and requires you to understand a whole lot than a normal programmer understands about computers. Your video gives the gist of what it needs to even write a very simple bootable software. Love your work man and thanks for sharing the Github code as it may help someone who is as cool as you.
When I started coding I thought using libaries was some sort of cheating, as I basically just ran someone else's program which I couldn't write myself. This guy took that thought to a whole nother level
even the people who wrote the libraries were cheating ... since they used a high level programming language ... only the people who wrote C didnt cheat :)
Honestly I hate using libraries because I don't understand how they are supposed to work a lot of the time and they are often very slow

Beautiful. I wrote an OS for fun too (back in the early 2000s). It had a bootloader, never left Real Mode, and could display a command prompt, and that was it! I was incredibly happy when I put the image onto a 3.5" floppy and it actually booted on my machine (modern machines with UEFI instead of a BIOS would have been much harder). Then I proceeded to never look at it again and question my life choices.

@@Henrix1998 and doing
you will need some knowledge of computer architecture, core concepts of operating systems and some skill in assembly. A few books that can help you with that:
- Programming From The Ground Up by Jonathan Bartlett: teaches you x86 assembly, a bit of computer architecture and other things
- Operating System Concepts by Avi Silberschatz, Greg Gagne, and Peter Baer Galvin: it's a great introduction to operating systems, it teaches you how the operating system interfaces with hardware, how the operating system gives support to the user space programs etc. It will teach you much more than it's needed to built what's on the video tho.
- manuals on the hardware you're trying to write software to
- for writing drivers there are a lot of books about drivers on linux, they might give you a good idea how to do it
I've added some resources in the description that I used when I started learning this stuff a few years back :)
@@jdh Thank you very much!
When i implemented a bare-metal Tetris for an ARMv7 i used a list of coordinate offsets from the center of the tetris block instead of a matrix containing bits - that makes rotation much easier because you can just use rotation matrices
