RichARCH
Your concierge creating a Rich experience to Arch
RichARCH is designed to be a Quick Simpler Path to Arch with automation and ricing options. * Just one command to start the latest complete installer for Arch. One goal is to only use packages in the basic Arch Linux repos by default with the option to install some non-standard packages. Our hope is that this will help to make Arch Linux more approachable to individual and corporate users.

unc0ver
The most advanced jailbreak tool
unc0ver is an advanced jailbreak tool for iOS 11.0 - 12.2. It's a jailbreak tool that stands out above the rest, as it it just one app that can jailbreak all firmwares. It's also got full-fledged Cydia and Substrate support, and Telesphoreo port for ARM64 devices. It can rejailbreak from the jailbroken state, offers options and utilities for the user, and many more. unc0ver doesn't share private data for diagnostics purposes, and has no inefficient local jailbreak server (jailbreakd daemon). It offers better system security, better performance and more efficient use of battery life. Switching from other jailbreaks to unc0ver is fairly easy and safe. Dedicated migration support ensures that you can make the switch without losing valuable data. -

WSL2-Linux-Kernel
The source for the Linux kernel used in Windows Subsystem for Linux 2
The WSL2-Linux-Kernel repo contains the kernel source code and configuration files for the WSL2 kernel. If you discover an issue relating to WSL or the WSL2 kernel, please report it on the WSL GitHub project. It is not possible to report issues on the WSL2-Linux-Kernel project. Instructions for building an x86_64 WSL2 kernel with an Ubuntu distribution are provided. The number one way that we recommend you run Linux distributions is by installing Windows Terminal. Using Windows Terminal enables you to open multiple tabs or window panes to display and quickly switch between multiple Linux distributions or other command lines (PowerShell, Command Prompt, PowerShell, Azure CLI, etc). You can fully customize your terminal with unique color schemes, font styles, sizes, background images, and custom keyboard shortcuts. -

QP Real-Time Event Frameworks & Tools
Real-Time Event Frameworks based on active objects & state machines
QP real-time event frameworks (RTEFs) provide lightweight, modern, event-driven architecture based on asynchronous Active Objects (Actors) and Hierarchical State Machines. The matching QM model-based design tool and other host-based tools complement the QP frameworks by supporting graphical modeling, code generation, software tracing, and unit testing for event-driven embedded software. Visit https://www.state-machine.com for more information. The QP RTEFs can run on bare-metal microcontrollers, replacing a traditional RTOS. The frameworks contain a selection of built-in real-time kernels (RTOS kernels), such as the cooperative QV kernel, the preemptive non-blocking QK kernel, and the unique preemptive, dual-mode (blocking/non-blocking) QXK kernel. Native QP ports and ready-to-use examples are provided for ARM Cortex-M (M0/M0+/M3/M4/M7/M33/...) as well as other CPUs. The QP RTEFs can also work with many traditional RTOSes and General-Purpose OSes, such as Linux and Windows. -

ravynOS
A BSD-based OS project that aims to provide an experience with MacOS
We love macOS, but we’re not a fan of the ever-closing hardware and ecosystem. So we are creating ravynOS, an OS aimed to provide the finesse of macOS with the freedom of FreeBSD. This is a developer preview image that’s mainly intended for helping build the system. We recommend running in a virtual machine, although it should work on any hardware supported by FreeBSD-CURRENT (14.0) with at least 2GB (8GB recommended) RAM. PLEASE NOTE: On 2022-02-14, we decided to abandon the current path of using X11/KDE desktop components and write from scratch a new UI that will align better with our goals. This stepping back will slow the project but ultimately should result in a better outcome. We intend to bring many of the features you’ve come to love from macOS to ravynOS like clean design, global menus, and drag-and-drop installs. All of your FreeBSD ports and apps, Linux apps, and even trivial Darwin & macOS binaries can now run on ravynOS. And we’re actively working on improving it! -
