    iOS WebKit Debug Proxy

    iOS WebKit Debug Proxy

    A DevTools proxy for iOS devices

    The ios_webkit_debug_proxy (aka iwdp) proxies requests from usbmuxd daemon over a websocket connection, allowing developers to send commands to MobileSafari and UIWebViews on real and simulated iOS devices. iOS WebKit Debug Proxy works on Linux, MacOS & Windows. The iOS Simulator is supported, but it must be started before the proxy. The simulator can be started in XCode, standalone, or via the command line. ios_webkit_debug_proxy can be used with many tools such as Chrome DevTools and Safari Web Inspector. To use Chrome DevTools it's the recommendation to use the RemoteDebug/remotedebug-ios-webkit-adapter project, which has instructions on how to setup Chrome to remote debug iOS devices, much similar to Android debugging. You can use Safari Web Inspector extracted from Webkit sources, e.g. artygus/webkit-webinspector. Another option is mozilla/valence which enables Firefox DevTools to be used with iOS.

    libusbmuxd

    libusbmuxd

    A client library to multiplex connections from and to iOS devices

    A client library for applications to handle usbmux protocol connections with iOS devices. This project is a client library to multiplex connections from and to iOS devices alongside command-line utilities. It is primarily used by applications that use the libimobiledevice library to communicate with services running on iOS devices. The library does not establish a direct connection with a device but requires connecting to a socket provided by the usbmuxd daemon. The libimobiledevice project provides an open-source reimplementation of the usbmuxd daemon to use on Linux or as an alternative to communicate with iOS devices without the need to install iTunes. The architecture of the library and dependencies has been designed with an OOP approach in mind. Thus bindings for other programming languages are easier to create and allow an OOP based API. Linux enthusiasts were not amused about great but incompatible hardware like the iPhone 2G.

    raspberry-pi-os

    Learning operating system development using Linux kernel and Raspberry

    This project provides a step-by-step educational guide on building a simple operating system kernel entirely from scratch, specifically targeting the Raspberry Pi 3. The operating system, referred to as RPi OS, is inspired by the Linux kernel but remains intentionally minimal to focus on clarity and teaching fundamental OS concepts. Each lesson introduces a kernel feature and demonstrates its implementation within RPi OS, followed by a comparison to how the same concept is realized in the Linux kernel. The repository is structured so that every lesson corresponds to a snapshot of the source code at that stage, making it easier for learners to follow the progression of kernel development. The design of the lessons emphasizes gradual learning, allowing readers without prior OS development experience to understand kernel internals. The project is still under active development and encourages community contributions to expand its lessons and improve its content.
