    Purpur

    Purpur

    Purpur is a drop-in replacement for Paper servers

    Purpur is an open-source Minecraft server software built as a fork of the Paper server platform, designed to provide extensive configurability and gameplay customization for server administrators. It functions as a drop-in replacement for Paper, meaning existing servers can switch to Purpur without major changes while gaining access to additional features and configuration options. The project focuses on allowing administrators to modify gameplay mechanics, behaviors, and rules that are normally fixed in standard server implementations. Through a wide set of configuration settings, server operators can adjust how mobs behave, alter game mechanics, or enable experimental gameplay features that are not present in vanilla Minecraft. Purpur inherits performance improvements and plugin compatibility from the Paper ecosystem while adding its own enhancements and customization capabilities.

    QR Code generator library

    QR Code generator library

    High-quality QR Code generator library in Java, TypeScript/JavaScript

    This project aims to be the best, clearest library for generating QR Codes. My primary goals are flexible options and absolute correctness. The secondary goals are compact implementation size and good documentation comments. This work is an independent implementation based on reading the official ISO specification documents. I believe that my library has a more intuitive API and shorter code length than competing libraries out there. The library is designed first in Java and then ported to TypeScript, Python, Rust, C++, and C. It is open source under the MIT License. For each language, the codebase is roughly 1000 lines of code and has no dependencies other than the respective language’s standard library.

    SQLFlow

    SQLFlow

    SQL compiler bridging databases and machine learning workflows

    SQLFlow is an open source project designed to bridge the gap between traditional SQL-based data processing and modern machine learning workflows by extending SQL syntax with AI capabilities. It acts as a compiler that translates SQL programs into executable workflows, enabling users to train, evaluate, and deploy machine learning models directly from SQL statements. It integrates with multiple database engines such as MySQL, Hive, and MaxCompute, while also supporting machine learning frameworks like TensorFlow and XGBoost. By embedding machine learning operations into SQL, it removes the need for users to switch between programming languages such as Python or R, simplifying the overall workflow. SQLFlow also supports model training, prediction, and explanation tasks, allowing data practitioners to work entirely within a familiar query interface.

    Starlight Fabric

    Starlight Fabric

    Rewrites the light engine to fix lighting performance

    Starlight is a performance optimization project for Minecraft that completely rewrites the game’s internal lighting engine to improve efficiency and reduce lighting-related lag. The original Minecraft lighting system can be computationally expensive when generating terrain or updating large structures, which can cause performance problems on servers and heavily modded environments. Starlight replaces this system with a redesigned algorithm that processes lighting calculations more efficiently and reduces the number of updates required for each chunk. The project aims to improve chunk generation performance, reduce lag spikes, and eliminate certain lighting bugs that occur in the vanilla engine. Because it fundamentally replaces the default lighting system, Starlight can significantly improve performance on servers handling large numbers of block updates or terrain generation tasks.

    XTDB

    XTDB

    General-purpose bitemporal database for SQL, Datalog & graph queries

    XTDB is a general-purpose bitemporal database for SQL, Datalog & graph queries. XTDB contains a perfect, immutable record of every fact your system has ever known. See the entire history of your business, everywhere. Immutable records are incomplete without time-traveling queries. XTDB allows you to query the entire timeline. Make retroactive corrections, simplify data migrations, and get clarity on out-of-order events. It is the interconnection of facts that makes them valuable. Query the relational model with SQL and the graph model with Datalog, over the same data. Explore all your data. Across all implicit relationships, across all time. As a document-oriented database, XTDB makes your data immediately available without the need for an upfront schema. Both structured and unstructured data are at home in XTDB. Legal regulations like GDPR often pose a challenge when designing systems around immutable data.
