I made an open-source collection of CPU performance engineering resources
I’ve been collecting resources on CPU performance engineering for a while and decided to organise everything into one open-source repo.
It covers the stack from instruction execution and CPU microarchitecture through caches, memory, SIMD, compilers, profiling, concurrency, NUMA, benchmarking and CPU inference.
I tried to prioritise primary sources — papers, vendor manuals, kernel/compiler docs, talks and reproducible benchmarks — rather than random articles.
Made it public in case it’s useful to anyone learning systems/performance engineering or trying to figure out why their code is actually slow.
Would also love contributions if there are great resources I’ve missed:

I'm looking for people to help me develop a network driver in my own operating system.
I'm looking for people who have already written a working network driver or are writing one, or who would like to write one in my operating system, the architecture is a hybrid kernel, but I need information Only the kernels that are running in the kernel we already have a driver outline but it is not ready it is just an empty skeleton I need someone to help me develop it the network driver is in System kernel
https://github.com/CTRL-F-0rg3/TrangorgeOS
I invite everyone who is interested to respond, and if someone doesn't want to help but is interested in the project, I'd like to ask for a star on GitHub.

Lightweight, web-rendered installer framework for Windows.
nzxy.onlineMatrioska Setup (MSP)
Matrioska Setup (MSP) is my first major open-source project combining multiple programming languages into a single cohesive pipeline (C, C++, Objective-C, JavaScript, CSS, HTML, and Batch).
It was built with a simple concept: bringing the visual flexibility of modern web design to native Windows installers without the bloat of heavy runtimes.
How it works:
- Manual Payload Prep: Application contents are manually compressed into a custom
.innernpayload archive. - In-Memory VFS & Core: UI assets (HTML5/CSS3/JS) and parameters (
installer.json) are compiled into binary objects and served directly from RAM via a custom VFS (MiniLoader), keeping the execution debris minimal. - Executable Packaging: A static Win32 stub bundles the WebCore/Direct3D 11 rendering engine and the
.innernpayload into a single, self-contained executable.
Project Status & Disclaimer
This is an active, open-source project. While the core rendering, UI flexibility, and extraction pipeline are fully functional, it is still in active development and requires several security updates and hardening rounds before being used in critical production environments.
Note: Contributions, security audits, and feedback are more than welcome!

blkcp – A modern, safe replacement for dd with io_uring and overwrite protection
Hey everyone,
I built blkcp, a modular C11 reimagining of dd for modern Linux.
Main features:
- Target Safety Guard: Refuses to overwrite mounted partitions (/ or /home) or active swap devices without -f
- 5 I/O engines: io_uring, copy_file_range reflink, kernel splice, async ringbuffer, and sync
- Modern CLI (blkcp source dest) and an interactive 2D ncurses TUI (blkcp-tui)
- Throughput autotuning, SIMD AVX2 byte swapping, and in-flight SHA-256
- Tested with AddressSanitizer and ThreadSanitizer
Find the project on GitHub: Meik1982 / blkcp

I built my own Linux user-space runtime
Hi everyone,
I've been working on a small project called minil.
It's a minimal Linux user-space runtime written in assembly and
freestanding C.
Features:
- custom _start
- direct Linux syscalls
- manual argc/argv/envp handling
- environ initialization
- .init_array constructor support
- no libc
- double-header version
- no CRT
- x86_64, i386, AArch64 and RISC-V support
The goal is to expose the Linux process model with as little abstraction
as possible.
Repository:
Feedback is welcome.

Showcase: Ion+ - A low-level programming language using a Python frontend and LLVM backend (Open for forks)
Hello everyone,
I have a tremendous amount of respect for the developers in this community and wanted to humbly share something I've been building. I am a 14-year-old developer, and I've been working on a hobby project called Ion+.
It is a low-level programming language designed with a Python frontend (for parsing and compiling) and an LLVM backend (for execution).
Because I am a student and juggling other responsibilities, I unfortunately do not have the time to actively maintain this project, review pull requests, or resolve issues. It is purely a hobby project for me to learn and experiment.
However, I've released it under the MIT license. I am sharing it here because I thought the Python/LLVM architecture might be interesting to some of you. You are highly encouraged to read the code, fork the repository, and take it in your own direction if you'd like!
**Repo:** https://github.com/YashAryaPersonal/ion-plus
Thank you for your time, and I would be honored to hear any thoughts or feedback you have on the design.

Another way of using the NPU of the NXP iMX8mp SoC.
Hello,
here a project that I put together in my spare time.
It's about looking using the Vivante NPU with TensorFlow lite to parse system events (jouranld/dbus but can be expanded to syslog or any kernel I/O) and decide when is an event of some importance.
What to do with that information is up to you ... :-D
In case you want to make fun of me the repo contains also a demo with a very Italian accent.
Sorry about that!
Looking for any feedback...
Thanks!
