exchange-core java
Ultra-fast matching engine written in Java based on LMAX Disruptor
Exchange-core is an open source market exchange core based on LMAX Disruptor, Eclipse Collections (ex. Goldman Sachs GS Collections), Real Logic Agrona, OpenHFT Chronicle-Wire, LZ4 Java, and Adaptive Radix Trees. HFT optimized. Priority is a limit-order-move operation mean latency (currently ~0.5µs). Cancel operation takes ~0.7µs, placing new order ~1.0µs. Pipelined multi-core processing (based on LMAX Disruptor): each CPU core is responsible for certain processing stage, user accounts shard, or symbol order books shard. -

Airsonic
Free and Open Source community driven media server
...You can stream to multiple players simultaneously, for instance to one player in your kitchen and another in your living room. Airsonic is designed to handle very large music collections (hundreds of gigabytes). Although optimized for MP3 streaming, it works for any audio or video format that can stream over HTTP, for instance AAC and OGG. By using transcoder plug-ins, Airsonic supports on-the-fly conversion and streaming of virtually any audio format, including WMA, FLAC, APE, Musepack, WavPack and Shorten. If you have constrained bandwidth, you may set an upper limit for the bit rate of the music streams. ... -

threadandjuc
High performance three-high-import import system
...It is designed to help developers understand how Java concurrent programming works through examples, explanations, and practical project-style demonstrations. The project covers topics such as threads, locks, synchronization, thread pools, concurrent collections, and high-performance data handling. It is especially useful for Java developers preparing for interviews or improving their understanding of production-level concurrency patterns. Some material also explores large-scale import and high-throughput reporting scenarios, connecting theory to real performance problems. Its main value is giving learners a structured way to study Java concurrency beyond isolated code snippets. -

ksqlDB
The database purpose-built for stream processing applications
...No other languages or services are required. ksqlDB enables you to build event streaming applications leveraging your familiarity with relational databases. Three categories are foundational to building an application: collections, stream processing, and queries. Streams are immutable, append-only sequences of events. They're useful for representing a series of historical facts. Tables are mutable collections of events. They let you represent the latest version of each value per key. -

TreasureBox
Organizes and searches user-defined items and images in a MySQL DB.
...By providing a zoom and rotate features I was able to browse my books or CDs on my shelves anywhere in the house. The more I used the program the more features I wanted to add. The program is fairly generic and can be used for a variety of collections within a tree structure. Digital images are easy to take and cost very little to store. Treasure Box can help you organize your treasures and help you find them when you need them. -

Basic, concurrent algorithm
...The repository emphasizes understanding over memorization, linking conceptual summaries with small code artifacts that can be compiled and profiled. It also highlights best practices around collections, thread safety, lock-free techniques, and performance trade-offs so learners can make informed design decisions. The material is structured to support incremental study, making it useful for both foundational learning and pre-interview refreshers. By bundling explanations with code and references, JCSprout acts as a compact “from student to engineer” handbook for the Java ecosystem. -

nervalreports
A lightweight report creation Java library
...Instead of the highly expensive way of well-known engines like Jasper Reports, where performance and data reiteration is a big and set aside problem (and also is the report design as a non-programming task), at Nerval Reports the data should be sent directly when iterating through it (ie: when using databases, one will create its report while iterating through the result set - instead of creating a bunch of collections to pass them to the library), and the design is mainly focused on programmer side. Also, one could include to its project just the exporters he/she is interested with, basing its choice on performance trade-offs, report file types and focused target projects. -
