Linux Deploy
Install and run GNU/Linux on Android
This application is open source software for quick and easy installation of the operating system (OS) GNU/Linux on your Android device. The application creates a disk image or a directory on a flash card or uses a partition or RAM, 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 can run better with superuser rights (root). The program supports multi language interface. You can manage the process of installing the OS, and after installation, you can start and stop services of the new system (there is support for running your scripts) through the UI. The installation process is reported as text in the main application window. -

OpenRocket
Model-rocketry aerodynamics and trajectory simulation software
OpenRocket is a free and fully featured simulation software for designing, analyzing, and optimizing model rockets before physical construction and launch. It provides a comprehensive environment where users can assemble rocket components, visualize designs in both 2D and 3D, and simulate flight behavior using accurate aerodynamic and physics models. The software incorporates six-degree-of-freedom flight simulation, allowing it to model real-world dynamics such as stability, drag, thrust, and staging effects. Users can analyze simulation outputs like altitude, velocity, and acceleration through detailed plots, enabling iterative improvements to rocket designs. OpenRocket also supports exporting designs for manufacturing processes such as 3D printing or laser cutting, bridging the gap between simulation and real-world prototyping. -

Planetiler
Flexible tool to build planet-scale vector tilesets
Planetiler (pla·nuh·tai·lr, formerly named "Flatmap") is a tool that generates Vector Tiles from geographic data sources like OpenStreetMap. Planetiler aims to be fast and memory-efficient so that you can build a map of the world in a few hours on a single machine without any external tools or database. Vector tiles contain raw point, line, and polygon geometries that clients like MapLibre can use to render custom maps in the browser, native apps, or on a server. Planetiler packages tiles into an MBTiles (SQLite) or PMTiles file that can be served using tools like TileServer GL or Martin or even queried directly from the browser. See awesome-vector-tiles for more projects that work with data in this format. Planetiler works by mapping input elements to vector tile features, flattening them into a big list, and then sorting by tile ID to group them into tiles. -

jackson-core
Core part of Jackson that defines Streaming API
This project contains core low-level incremental ("streaming") parser and generator abstractions used by Jackson Data Processor. It also includes the default implementation of handler types (parser, generator) that handle JSON format. The core abstractions are not JSON specific, although naming does contain 'JSON' in many places, due to historical reasons. Only packages that specifically contain the word 'json' are JSON-specific. This package is the base on which Jackson's data-binding package builds on. It is licensed under Apache License 2.0. Alternate data format implementations (like Smile (binary JSON), XML, CSV, Protobuf, and CBOR) also build on this base package, implementing the core interfaces, and making it possible to use standard data-binding packages regardless of underlying data format. -

ExoPlayer
An extensible media player for Android
ExoPlayer is an application level media player for Android. It provides an alternative to Android’s MediaPlayer API for playing audio and video both locally and over the Internet. ExoPlayer supports features not currently supported by Android’s MediaPlayer API, including DASH and SmoothStreaming adaptive playbacks. Unlike the MediaPlayer API, ExoPlayer is easy to customize and extend, and can be updated through Play Store application updates. ExoPlayer modules can be obtained from JCenter. It's also possible to clone the repository and depend on the modules locally. The easiest way to get started using ExoPlayer is to add it as a gradle dependency. You need to make sure you have the Google and JCenter repositories included in the build.gradle file in the root of your project. n addition to library modules, ExoPlayer has multiple extension modules that depend on external libraries to provide additional functionality. Some extensions are available from JCenter. -
