    RichARCH

    RichARCH

    Creating a Rich experience to ARCH

    RichARCH is designed to be a Simple Quick Pure path to Arch Linux with kickstart like automation features. One goal of the project is to only use packages in the basic Arch Linux repos by default with the option to install a few non-standard packages (like Pamac, Spotify, and Warp Terminal). Our hope is that this will help to make Arch Linux more approachable to individual and corporate users. Make sure to backup any data you wish to keep from the storage device you plan to use with the RichARCH installer.

    unc0ver

    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.

    QP Real-Time Event Frameworks & Tools

    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.

    WSL2-Linux-Kernel

    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.
