    Voy

    Voy

    A WASM vector similarity search written in Rust

    Voy is a lightweight WebAssembly-based vector similarity search engine written in Rust that enables semantic search capabilities directly in browser or edge environments. It is designed to operate on embeddings generated from text or other data, allowing applications to perform meaning-based search rather than simple keyword matching. The engine uses efficient data structures such as k-d trees to index vectors and perform fast nearest-neighbor queries, making it suitable for real-time search experiences. One of its key advantages is its extremely small footprint, allowing it to be deployed easily on CDNs or client-side applications without significant overhead. ...

    Moelnir

    Moelnir

    Heap organised database service (Java library)

    Moelnir is a basic database file, addressing variable record data through integer identifiers, which applies heap organisation of its data space. Advantage of Moelnir is that each record is stored in a continuous segment on the file while still record size is limit-less variable and modifiable. There are no data length limits other than the range of a 63-bit unsigned integer. Scalability is limited to 1 - 10 Mio. entries due to non-paging internal structures.

    CityHash

    CityHash

    Automatically exported from Google code CityHash

    ...CityHash offers multiple hash sizes—32-bit, 64-bit, 128-bit, and 256-bit variants—with the CRC-based versions leveraging hardware acceleration on CPUs that support SSE4.2 CRC32 instructions. The library emphasizes hashing performance and uniformity rather than cryptographic security, making it ideal for use in data structures like hash tables and distributed systems requiring rapid key lookups. CityHash has been rigorously tested using tools like SMHasher to ensure high-quality mixing and collision resistance across a wide range of inputs. Its speed and portability have made it a popular choice for developers needing dependable, lightweight hash functions.

    Cyclops

    Cyclops

    An advanced platform for writing functional applications in Java 8

    ...Structural Pattern Matching API (deconstruct algebraic product and sum types). Improved type safety via the removal of unsafe APIs -- E.g. Unlike Optional, Option has no get method (which could throw a null pointer) -- New data structures do not support operations that would throw exceptions (you can't call head on an empty list for example). Eager and Lazy alternatives for most datastructures (Option is eager, Maybe is lazy + reactive). Improved naming of types (Function1-8 rather than Fn1-8, Either not Xor). Group id is changed to com.oath.cyclops. Versioning between cyclops-react and cyclops is merged on cyclops versioning scheme (version 10 = Cyclops X).
