    whisper.cpp

    whisper.cpp

    Port of OpenAI's Whisper model in C/C++

    whisper.cpp is a lightweight, C/C++ reimplementation of OpenAI’s Whisper automatic speech recognition (ASR) model—designed for efficient, standalone transcription without external dependencies. The entire high-level implementation of the model is contained in whisper.h and whisper.cpp. The rest of the code is part of the ggml machine learning library. The command downloads the base.en model converted to custom ggml format and runs the inference on all .wav samples in the folder samples. whisper.cpp supports integer quantization of the Whisper ggml models. Quantized models require less memory and disk space and depending on the hardware can be processed more efficiently.

    Geode iOS Launcher

    Geode iOS Launcher

    Manages installing and launching Geometry Dash for iOS

    Geode iOS Launcher is a specialized utility designed to install, manage, and launch a modified version of Geometry Dash with Geode modding support on iOS devices, overcoming Apple’s restrictive app distribution policies through sideloading techniques. It acts as a bridge between the Geode modding ecosystem and iOS, enabling users to run modded versions of the game without requiring a traditional jailbreak. The application supports multiple installation methods, including SideStore, developer certificates, and other sideloading approaches, each offering different levels of functionality and compatibility. It incorporates mechanisms to enable or simulate Just-In-Time execution, allowing mods to function even under Apple’s limitations, including partial support through JIT-less execution modes. The launcher also integrates mod management features, letting users browse, install, and update modifications directly within the app environment.

    Connect your devices into a secure WireGuard-based overlay network

    NetBird is an open-source solution that builds a WireGuard®-based overlay network enabling seamless, encrypted peer-to-peer connectivity without the complexity of firewall rules, port forwarding, or centralized VPN gateways. It integrates access control features such as SSO and MFA for secure, policy-driven networking. Every machine in the network runs NetBird Agent (or Client) that manages WireGuard. Every agent connects to Management Service that holds network state, manages peer IPs, and distributes network updates to agents (peers). NetBird agent uses WebRTC ICE implemented in pion/ice library to discover connection candidates when establishing a peer-to-peer connection between machines.

    Brook

    Brook

    Brook is a cross-platform strong encryption and not detectable proxy

    Brook is a cross-platform strong encryption and not detectable proxy. Brook's goal is to keep it simple, stupid and not detectable. You can run commands after entering the command-line interface. Usually, everyone uses the command line interface on Linux servers. Of course, Linux also has desktops that can also run GUI. Of course, macOS and Windows also have command-line interfaces, but you may not use them frequently. Usually, the applications opened by double-clicking/clicking on macOS/Windows/iOS/Android are all GUIs. Usually, if you use Brook, you will need a combination of Server and Client, Of course Brook CLI also has many other independent functions. The Brook CLI file is an independent command file, it can be said that there is no concept of installation, just download this file to your computer, run it after granting it executable permissions in the command line interface.

    pkg

    Package your Node.js project into an executable

    This command line interface enables you to package your Node.js project into an executable that can be run even on devices without Node.js installed. Make a commercial version of your application without sources. Make a demo/evaluation/trial version of your app without sources. Instantly make executables for other platforms (cross-compilation). Make some kind of self-extracting archive or installer. No need to install Node.js and npm to run the packaged application. No need to download hundreds of files via npm install to deploy your application. Deploy it as a single file. Put your assets inside the executable to make it even more portable. Test your app against new Node.js version without installing it. pkg was created for use within containers and is not intended for use in serverless environments. For those using ZEIT Now, this means that there is no requirement to use pkg in your projects as the benefits it provides are not applicable to the platform.

    Homebridge Docker Image

    Homebridge Docker Image

    HomeKit support for the impatient using Docker on x86_64

    This Ubuntu Linux based Docker image allows you to run Nfarina's Homebridge on your home network which emulates the iOS HomeKit API. This is a multi-arch image and will run on x86_64, Raspberry Pi 2, 3, 4, Zero 2 W, or other Docker-enabled ARMv7/8 devices. Docker will automatically pull the correct image for your system. Homebridge requires full access to your local network to function correctly. This image will not work when using Docker for Mac or Docker for Windows. The parameters are split into two halves, separated by a colon, the left-hand side representing the host and the right container side. This image comes with the Homebridge UI pre-installed and is the easiest way to manage all aspects of Homebridge. Automated updates of the Homebridge Docker Image using tools such as Watchtower or similar are strongly discouraged and are done so at your own risk. You can update Homebridge, the Homebridge UI and the Node.js runtime from inside the container.

If you'd like to help support our development, or take over the development please let us know. Explore the internal file structure of your iphone (or of a seized phone in the case of forensic teams) using either the iphone's own backup files or (for jail broken iphones) ssh. Viewing of plist, sqlite, and hex are supported. IOS 5 is now supported iOS 6 only partially works at the moment (some features fail or are missing). Unfortunately paid work means we can't fix this right now, but would welcome anyone else submitting patches.

    Play!

    Play! - PlayStation2 Emulator

    Play! is an open-source cross-platform emulator for Sony’s PlayStation 2 that aims to run PS2 games on a wide range of modern systems including Windows, macOS, Linux, Android, iOS, and web browsers by implementing core PS2 hardware functionality in software. It emulates primary components like the Emotion Engine CPU and graphics synthesizer, translating game code and hardware calls into host system operations, while providing users with controls to load disc images, manage states, and configure rendering options. Because the PS2’s architecture is complex and proprietary, Play! pursues compatibility incrementally, with many titles playable to varying degrees and an active compatibility tracker detailing individual game status. The project supports optimizations such as JIT code generation on compatible platforms to improve performance and offers a broad set of build targets so developers and users can experiment with different back ends and environments.
