Hi HN, I’m Dvir, a young developer. Last year, I got rejected after a job interview because I lacked some CPU knowledge. After that, I decided to deepen my understanding in the low level world and learn how things work under the hood. I decided to try and create an OS in C and ASM as a way to broaden my knowledge in this area. This took me on the most interesting ride, where I’ve learned about OS theory and low level programming on a whole new level. I’ve spent hours upon hours, blood and tears, reading different OS theory blogs, learning low level concepts, debugging, testing and working on…

Hello HN, I've been working on a simple OS for tinkering and running bare metal apps on vintage PCs. Since I couldn't quite decide whether to target pure 16-bit, or slightly more capable 32-bit machines, I ended up with two separate versions: - GentleOS/32 (https://github.com/luke8086/gentleos32) works on i386+, requires 4MB of RAM and VGA display supporting 640x480x16 mode or any 256-color VESA mode. - GentleOS/16 (https://github.com/luke8086/gentleos) works on 80186+, requires less than 192KB of RAM and a CGA display supporting 320x200x4…

I've wanted to make my own OS since I started programming. Now, 5 years later, I did it (kind of). Sure, it is really basic, has very little functionality, but I made it and I'm proud of that. Oh, and I'm just 16 btw.

Hello HN, these Mini Trees have a custom circuit board with WS2812 addressable LEDs on one side and a controller using an RP2040 microcontroller on the other, all inside a CNC'd Foamex PVC case. They stand around 23cm (9") tall. The firmware is written in MicroPython, which can be modified or replaced. Power is provided via USB-C, which is also used for programming. There is also a web-based animation sequencer to create lighting sequences in time to arbitrary audio, examples of which are on the linked page. This is similar to xLights (https://xlights.org/), but much less…

VEKOS(Verified Experimental Kernel OS) is a Rust-based experimental kernel that focuses on runtime verification and security. Every filesystem operation and memory allocation generates cryptographic proofs that can be verified in real-time, ensuring system integrity. Think of it like a blockchain for OS operations rather than just storage verification. Key features: - Merkle tree-backed filesystem with operation verification - Memory manager with CoW and proof generation - Buddy allocator with zone-based memory management - Shell with VT100 support - Verified boot sequence with stage…

This project contains no code from Linux, BSD, Minix, or any other OS. Everything up until this point is written entirely from scratch, including a pure microkernel (that only implements multiprocessor priority scheduling, memory management, and interprocess communication), a work-in-progress implementation of the standard C library, and a variety of servers that provide drivers and other essential OS functionality. At the time of writing this post, the servers provide drivers for the keyboard, NVMe SSDs (that works on real hardware), a Unix-like virtual file system (with a single root…

Yes, this includes the MBR and partition boot sector. The partition table is modeled as a class hierarchy. Second stage loads a kernel from a FAT32 file. I'm normally a C programmer, but for a work project, I recently revisited C++, a language that I had an on-again-off-again relationship over the years. I did this as a fun training exercise on the side to get familiar with the language again, but obsessed a bit and kind of overshot the target. I thought the result might be of interest to someone.
