    LMAX Disruptor

    High performance inter-thread messaging library

    LMAX aims to be the fastest trading platform in the world.

    Spring Boot Examples

    Spring Boot Examples

    Spring Boot tutorials, technology stack example code

    spring-boot-examples is a collection of small, runnable projects that teach Spring Boot “by example,” emphasizing minimal dependencies and practical, copy-pasteable patterns.

The author notes that all examples have been updated to Spring Boot 3.0, with earlier 1.x and 2.x code paths kept accessible for reference. Each sample focuses on a single topic—such as Web MVC, WebFlux, Thymeleaf, JPA/MyBatis CRUD, file upload, Redis/MongoDB, RabbitMQ, and containerization—so you can learn one concept at a time and compose them later. ...

    Novel Insight Inner Circle

    Novel Insight Inner Circle

    Graphical message and file encryption tool

    ...The encryption uses AES-256 twice so it is harder to crack than the industry standard pure AES 256bit implementation (theoretical key size is 512 bit). The software writes encrypted data in ASCII text format which can be cut'n'pasted to messaging apps or to emails and back to Inner Circle when decrypting data. IMPORTANT: The software requires new OpenJDK 16 (Not Oracle's J2RE 1.8) to run. Install, for example, AdoptOpenJDK for Windows. NOTE: By using encryption twice the implementation is (in theory) vulnerable to Meet-In-The-Middle attack reducing key size to 256bit but the attack still requires 2^256 bytes of memory making it impossible in practice.
