    ArkOS

    ArkOS

    Another rockchip Operating System

    Another rockchip Operating System. This OS came about from an initial fork of The Retro Arena to support a roms folder on a NTFS partition so that the management of roms could be done by simply putting you SD card into an appropriate card reader on a Windows 10 computer. Through various upgrades and tweaks overtime, it has diverged significantly from TheRA and it's time to rebrand this distro. With suggestions provided by community members, ArkOS was chosen.

    Window Maker Live

    Window Maker Live

    Window Maker Live Linux Distribution

    Window Maker Live is an installable Linux Live ISO based on the current Trixie branch of Debian. The system uses the Window Maker window manager as the default graphical user interface. Window Maker Live's components have been carefully preconfigured and the desktop environment has a consistent visual appearance. Window Maker Live integrates selected components from other desktop environments such as XFCE4, MATE, LXQT, with a particular focus on GNUstep. The main idea behind this project is to integrate the Window Maker window manager as default user interface on top of a standard Debian/Trixie base system. It also serves as an alternate installation medium for Debian/Trixie. The second main idea not directly visible on the surface level is the inclusion of many useful command line utilities and tools for system administration. This effectively turns wmlive into a UNIX administrator's workbench for rescue and repair operations.

    HiddenVM

    HiddenVM — Use any desktop OS without leaving a trace

    If at any time Tails pushes an unexpected update, and HiddenVM is not yet updated for it, and you are stuck with a new Tails and no working HiddenVM version, you can re-download and temporarily use an earlier version of Tails until HiddenVM is updated. There are archived direct HTTP download mirrors of Tails images, archived official torrents with PGP signatures, or third-party archives at linuxtracker.org or fosstorrents.com, etc. (Always verify third-party torrents with archived official PGP sigs for safety.) Unless there is a known security vulnerability patched by the new Tails that actually affects how you use Tails, doing a temporary downgrade is not unsafe. You aren't necessarily unsafe by using older-than-one-month-old Tails software for a short time. Thank you for your patience, and stay safe.

    Mobilinux - Linux for Android

    Mobilinux - Linux for Android

    This application will allow you to install and run Linux on Android !

    The app supports ROOTED as well as NOROOTED devices. Use your mobile as a Pocket PC !! For Root Method: The application creates a disk image on a flash card, mounts it and installs an OS distribution. Applications of the new system are run in a chroot environment and working together with the Android platform. All changes made on the device are reversible, i.e. the application and components can be removed completely. Installation of a distribution is done by downloading files from official mirrors online over the internet. The application requires superuser rights (ROOT).Installing a new operating system takes about 15 minutes. The recommended minimum size of a disk image is 1024 MB (with LXDE), and without a GUI - 512 MB. Noroot Method: Install MOBICONSOLE addon and then install the linux on a non-rooted phone.

    BerserkArch is a security-focused, performance-tuned Linux operating system (OS) based on Arch Linux, designed for developers, hackers, and technical users. A bleeding-edge, security-centric Arch-based Linux distribution crafted for hackers, developers, and nerds alike. Following the Arch Linux philosophy, it is designed to be highly customizable, allowing users to build their environment with only the components they need, rather than having a lot of pre-installed software like some other security distributions (e.g., Kali Linux). As an Arch-based distribution, it benefits from the rolling release model, providing users with the latest software versions and kernel updates. BerserkArch is a dist "designed to make you powerful" for specific use cases like reverse-engineering binaries and automating exploits, rather than being an easy-to-use distribution for general beginners.
