    SeedCrackerX

    SeedCrackerX

    Minecraft mod designed to reverse-engineer

    SeedcrackerX is a Minecraft mod designed to reverse-engineer and determine a world’s seed by analyzing in-game structures and environmental data. It operates by collecting information from structures such as shipwrecks, temples, and monuments, then using that data to progressively narrow down possible seeds until the correct one is identified. The mod automates much of this process, initiating cracking procedures once sufficient data has been gathered, often requiring only exploration of specific structures. ...

    BIMserver

    BIMserver

    The open source BIMserver platform

    The Building Information Model server (short: BIMserver) enables you to store and manage the information of a construction (or other building related) project. Data is stored in the open data standard IFC. The BIMserver is not a fileserver, but it uses a model-driven architecture approach. This means that IFC data is stored as objects. You could see BIMserver as an IFC database, with special extra features like model checking, versioning, project structures, merging, etc. The main advantage of this approach is the ability to query, merge and filter the BIM model and generate IFC output (i.e. files) on the fly. ...

    RxJava

    RxJava

    Reactive Extensions for the JVM

    ...It helps you write cleaner and simpler code by providing methods for solving problems quickly, and is easy to maintain and understand. RxJava works by extending the observer pattern in order to support sequences of data/events. It also allows you to compose sequences together declaratively through added operators, all while abstracting away concerns like low-level threading, thread-safety, concurrent data structures and synchronization. RxJava is commonly used for running simple background computations. It supports Java 6 or higher and languages that are based on JVM such as JRuby, Groovy and Clojure.

    RoaringBitmap

    RoaringBitmap

    A better compressed bitset in Java

    Bitsets, also called bitmaps, are commonly used as fast data structures. Unfortunately, they can use too much memory. To compensate, we often use compressed bitmaps. Roaring bitmaps are compressed bitmaps which tend to outperform conventional compressed bitmaps such as WAH, EWAH or Concise. In some instances, roaring bitmaps can be hundreds of times faster and they often offer significantly better compression.

    TypeDB: a strongly-typed database

    ...TypeDB provides a strong type system for developers to break down complex problems into meaningful and logical systems. Through TypeQL, TypeDB provides powerful abstractions over low-level and complex data patterns. TypeDB allows you to model your domain based on logical and object-oriented principles. Composed of entity, relationship, and attribute types, as well as type hierarchies, roles, and rules, TypeDB allows you to think higher-level, as opposed to join-tables, columns, documents, vertices, edges, and properties.Types provide a way to describe the logical structures of your data, allowing TypeDB to validate that your code inserts and queries data correctly.
