    Spring Cloud Examples

    Spring Cloud Examples

    Spring Cloud learning cases, service discovery, service governance

    The Spring Cloud Examples repository appears to be a collection of sample applications and demos that illustrate how to use Spring Cloud and related cloud-native patterns in real-world microservice or distributed-service contexts. It provides working codebases showing how to wire together service discovery, configuration, inter-service communication, and possibly resilience patterns — giving developers a hands-on playground rather than theoretical documentation. By studying the examples, one can understand how Spring Cloud works in practice: how to structure services, how to configure them, and how they interact under realistic conditions. ...

    AhoCorasickDoubleArrayTrie

    AhoCorasickDoubleArrayTrie

    An extremely fast implementation of Aho Corasick algorithm

    AhoCorasickDoubleArrayTrie is a Java implementation of the Aho–Corasick multi-pattern matching algorithm that is optimized using a Double-Array Trie data structure. It is designed for fast keyword scanning across large texts, where you want to search for many patterns simultaneously and efficiently. The core idea is to build an automaton from a dictionary of patterns, then stream through input text to emit matches with minimal overhead. By using a double-array trie representation, the project emphasizes performance and memory efficiency compared to simpler pointer-heavy trie structures, which can matter a lot for large dictionaries or latency-sensitive services. ...

    DiagonalLayout

    DiagonalLayout

    Explore new styles and approaches on material design

    DiagonalLayout is another Android UI library aimed at enabling non-rectangular, more dynamic layout patterns: it provides a custom layout container whose sides (top, bottom, left, right) can be clipped diagonally, producing slanted, angled UI containers. This is especially useful when you want to build visually striking, non-conventional layouts — e.g. a header section on a profile screen with a diagonal bottom edge, a card with angled border, or image backgrounds slanted across the screen. ...

    AndroidEventBus

    AndroidEventBus

    Library for android, simplifies communication between services

    ...It allows developers to define and post custom events that can be observed by multiple parts of an app, such as UI controllers, services, or background workers, without requiring direct references between senders and receivers. Unlike simple observer patterns, AndroidEventBus typically integrates with Android lifecycles so that subscribers are automatically registered, paused, or cleaned up based on activity/fragment state — reducing memory leaks and errant behavior during configuration changes. The library aims to simplify common inter-component messaging tasks (like posting a login success event or notifying multiple listeners of state changes) while preserving type safety and performance.
