    OpenMTP

    OpenMTP

    Advanced Android File Transfer Application for macOS

    Transferring files between macOS and Android or any other MTP device has always been a nightmare. There are a few File Transfer MTP apps that are available online but most of them are either too expensive or come with bad UI/UX. The official "Android File Transfer" app for macOS from Google comes with bugs, and innumerable limitations, some of which include - not being able to transfer files larger than 4GB, frequent disconnections, unable to rename the folders or files on the android/MTP devices. Most of the other apps available online use either WiFi or ADB protocol to transfer the files, which is an extremely time-consuming process. Countless searches to find an app to solve these problems and failing to find one made me restless. So, I took the leap and decided to create an app for us that could help us have a smooth and hassle-free file transfer process from macOS to Android/MTP devices.

    Shaka Player

    Shaka Player

    JavaScript player library / DASH & HLS client / MSE-EME player

    Shaka Player is an open-source JavaScript library for adaptive media. It plays adaptive media formats (such as DASH and HLS) in a browser, without using plugins or Flash. Instead, Shaka Player uses the open web standards MediaSource Extensions and Encrypted Media Extensions. Shaka Player also supports offline storage and playback of media using IndexedDB. Content can be stored on any browser. Storage of licenses depends on browser support. Our main goal is to make it as easy as possible to stream adaptive bitrate video and audio using modern browser technologies. We try to keep the library light, simple, and free from third-party dependencies. Everything you need to build and deploy is in the sources. We support iOS 12+ through Apple's native HLS player. We provide the same top-level API, but we just set the video's src element to the manifest/media. So we are dependent on the browser supporting the manifests.

    V Programming Language

    V Programming Language

    Simple, fast, safe, compiled language for developing software

    Simple language for building maintainable programs. You can learn the entire language by going through the documentation over a weekend, and in most cases, there's only one way to do something. This results in simple, readable, and maintainable code. Despite being simple, V gives a lot of power to the developer and can be used in pretty much every field, including systems programming, webdev, gamedev, GUI, mobile, science, embedded, tooling, etc. V avoids doing unnecessary allocations in the first place by using value types, and string buffers, promoting a simple abstraction-free code style. Most objects (~90-100%) are freed by V's auto-free engine: the compiler inserts necessary free calls automatically during compilation. A remaining small percentage of objects is freed via GC. The developer doesn't need to change anything in their code. "It just works", like in Python, Go, or Java, except there's no heavy GC tracing everything or expensive RC for each object.
