Gradle Retrolambda Plugin
A gradle plugin for getting java lambda support in java 6, 7
This plugin will automatically build your java or android project with retrolambda, giving you lambda goodness on java 6 or 7. It relies on the wonderful retrolambda by Esko Luontola. The minimum android gradle plugin is 1.5.0 and the minimum gradle plugin is 2.5. The plugin will compile the source code with java8 and then replace the class files with the output of retrolambda. Set the java version to compile to. The default is 6. Only 5, 6 or 7 are accepted. The default version of retrolambda used is 'net.orfjackal.retrolambda:retrolambda:2.5.6'. If you want to use a different one, you can configure it in your dependencies. If you are running with java 6 or 7 you should really consider updating. First try updating to the latest version of the android gradle plugin. Newer versions of lint are compatible with java 8 sources. -

Growth
Growth engineering, the definitive guide
This is a guide book, so don't expect to learn all the knowledge points from this book, but it can help you build your knowledge system. We all learn, but sometimes we just don’t know what to learn. This is also lacking in other technical books. It can tell you what you can study and then what books to read. For some people, the reason for becoming a full stack is small and medium-sized companies from the society can hardly survive with only one field of knowledge. For some people, becoming a full stack comes because there is so much fun in this world. It's a shame to hang from a tree. For some people, the reason for becoming a full stack is they want to start a business. And people have too many misunderstandings about the full stack-they think that the full stack should do everything and be proficient in everything. The full stack is just because we have a holistic understanding of the system, rather than proficient in the entire system. -

Hardcoder
Hardcoder is a solution which allows Android APP and Android System
Hardcoder is a solution that allows Android APP and Android System to communicate with each other directly, solving the problem that Android APP could only use system standard API rather than the hardware resources of the system. Through Hardcoder, Android APP can make good use of mobile phone hardware resources such as CPU frequency, Large Core, and GPU to improve APP performance. Hardcoder allows Android system to get more information from the APP in order to better provide system resources to Android APP. At the same time, due to the lack of implementation by the standard interface, the APP and the system can also realize the model adaptation and function expansion through the framework. Hardcoder framework can averagely optimize the performance of Wechat by 10%-30% in terms of Wechat startup, video delivery, mini program startup, and other highly-loaded scenes. Furthermore, it could also averagely optimize the performance of Mobile QQ by 10%-50% in terms of mobile QQ startup. -

Highlight Library
A library for app directivity highlighting
Highlight is an Android onboarding and guidance library that draws an overlay to visually emphasize specific UI elements and attach tip content, helping users discover features inside an app. It works by placing a translucent mask over a chosen “anchor” area (often the activity content view) and then “cutting out” or spotlighting target views so they stand out clearly. Developers can define one or more highlighted targets, supply a custom tip layout (for example, an arrow plus text), and position that tip precisely using layout callbacks that provide measurements like margins and bounding rectangles. This makes it well-suited for guided tours, feature callouts after an update, or contextual help flows that need accurate placement across different screen sizes. The library supports highlighting within partial regions as well as full-screen overlays, letting you scope the effect to a specific container when needed. -

History of Everything
Flutter Launch Timeline Demo
HistoryOfEverything is a Flutter app that visualizes a vertical timeline from the Big Bang to the modern Internet. Users can scroll, zoom, and explore detailed events, reading extended articles with animation and illustrations. It was originally a demonstration/showcase project by 2Dimensions. This is the initial view for the app when it opens up. It shows a search bar on top, three menu sections for each major time era, and three buttons on the bottom for accessing favorites, sharing a link to the store, and the about page. This view is displayed when an item from the menu is selected: the user is presented with a vertical timeline. It can be scrolled up and down, zoomed in and out. When an event is in view, a bubble will be shown on screen with a custom animated widget right next to it. By tapping on either, the user can access the ArticlePage. -

IPDrone
Track Location With Live Address And Accuracy In Termux
IPDrone is a small Python utility for Termux that looks up information associated with a supplied IP address. It presents network and geolocation metadata returned for the address, including an estimated geographic location. The project describes this as live location tracking, but IP geolocation does not provide a device's precise GPS position and can be inaccurate or resolve only to a city or network region. The script is intended to run on both rooted and non-rooted Android devices through Termux. Its functionality is much narrower than the repository's more aggressive security tools and centers on IP lookup rather than device compromise. It is best used for authorized network diagnostics, research, or approximate geolocation where the limitations of IP-based location data are understood. -

KMath
Kotlin mathematics extensions library
Could be pronounced as key-math. The Kotlin Mathematics library was initially intended as a Kotlin-based analog to Python's NumPy library. Later we found that kotlin is a much more flexible language and allows superior architectural designs. In contrast to numpy and scipy it is modular and has a lightweight core. The numpy-like experience could be achieved with math-for-real extension module. -

KitX
An all-purpose toolbox app that connect everything
KitX is an open and extensible tools platform that enables users to create, share, and connect modular functionality through a plugin-based architecture. The system is designed around the concept of atomized functions, where each plugin provides small, independent capabilities that can be dynamically combined to form more complex workflows. Developers can build plugins using their preferred programming languages and frameworks, then distribute them through a shared marketplace where users can discover and install them. One of the key ideas behind KitX is cross-device connectivity, allowing functions to be executed across multiple user devices seamlessly through coordinated actions. The platform acts as an orchestration layer, managing communication between plugins and handling user input, device selection, and execution flow. This enables scenarios where a single user action can trigger a chain of operations across different devices and tools. -

KotCity
KotCity, an open source city simulator
This is pre-alpha software with super obvious bugs, rough edges, etc. In the spirit of "release early and release often", I am posting the code. This project is far from done but I prefer to get the code out there to be used by whomever. KotCity is a city simulator written in Kotlin inspired by the statistical city simulators of old. This game aims to achieve a mark somewhere between SimCity (1989) and SC2000. Hopefully, this mark will be hit and we can set our sights higher. The game will be fully supported on Windows, macOS, and Linux. -
