    Light-4J

    Light-4J

    A fast, lightweight and more productive microservices framework

    Light means lightweight, lightning-fast and shedding light on how to program with modern Java SE for cloud-native deployment. I had been working on the Java EE platforms since early 2000 and suffered performance and productivity issues. In 2014, I realized that the IT industry was moving from Monolithic to Microservices and from on-premise data centers to the public clouds. To reduce the production cost for my applications, I need to find a lightweight platform that has a small memory footprint, high throughput, and low latency in Java. Java EE and Spring/Spring Boot are too heavy to be considered. Other lightweight Java platforms all have different issues on the separation between the business logic and technical cross-cutting concerns. Moreover, they are not cloud-native or designed for container/cloud.

    Litho

    Litho

    A declarative framework for building efficient UIs on Android

    Litho uses a declarative API to define UI components. You simply describe the layout for your UI based on a set of immutable inputs and the framework takes care of the rest. With code generation, Litho can perform optimisations for your UI under the hood, while keeping your code simple and easy to maintain. Litho can measure and layout your UI ahead of time without blocking the UI thread. By decoupling its layout system from the traditional Android View system, Litho can drop the UI thread constraint imposed by Android. Litho uses Yoga for layout and automatically reduces the number of ViewGroups that your UI contains. This, in addition to Litho's text optimizations, allows for much smaller view hierarchies and improves both memory and scroll performance.
