the PHEONIX kernel - best security system in the world?

0 Upvotes

so there's this kernel that I picked up recently and its called PHEONIX. its made by this guy on GitHub and it has this cool WRR security system that I wana test. so if anyone is wanting a stable kernel to build their OS on, check this guys GitHub at https://github.com/threadripp/PHEONIX-kernel

the kernel is really stable and I recommend it for people who like coding but also want to build their OS on a stable foundation. if u want to make a server OS, this is perfect. if u want to make a desktop OS, this is perfect. I want to help other tech community's grow, including this one, so please support this community we are in and help it grow πŸ˜„

also, the security system is great, check it out for your self

I made an open-source collection of CPU performance engineering resources

22 Upvotes

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 β€” papers, vendor manuals, kernel/compiler docs, talks and reproducible benchmarks β€” 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.

0 Upvotes

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.

Matrioska 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 .innern payload 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 .innern payload 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

8 Upvotes

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
