    Q4OS

    Q4OS

    Efficient, Rock Stable Operating System

    Q4OS is a fast and friendly, desktop oriented operating system based on Debian Linux. It deploys Plasma, optionally Trinity, as desktop environment on top of Debian Linux rock stable base. The goal is to provide long-term supported system with a special emphasis on security. This is exactly what Debian base guarantees. We prefer the Debian development model to keep the core system as immutable as possible. It results in a reliable and stable system that you can definitely rely on. Thanks to unique Q4OS tools a user can rather easily achieve setup of a fitted system eliminating superfluous packages and libraries. Therefore Q4OS performs faster and more efficient, doesn't exploit memory and computing resources with useless tasks and processes. Another exclusive Q4OS feature is an optimized support for setting up Trinity desktop environment alongside the default Plasma desktop. Installed side by side, carefully separated, both ready to run as needed. Just select one at login.

    DeepFaceLab

    The leading software for creating deepfakes

    DeepFaceLab is currently the world's leading software for creating deepfakes, with over 95% of deepfake videos created with DeepFaceLab. DeepFaceLab is an open-source deepfake system that enables users to swap the faces on images and on video. It offers an imperative and easy-to-use pipeline that even those without a comprehensive understanding of the deep learning framework or model implementation can use; and yet also provides a flexible and loose coupling structure for those who want to strengthen their own pipeline with other features without having to write complicated boilerplate code. DeepFaceLab can achieve results with high fidelity that are indiscernible by mainstream forgery detection approaches. Apart from seamlessly swapping faces, it can also de-age faces, replace the entire head, and even manipulate speech (though this will require some skill in video editing).
