"This is a Neo4j client library for the HTTP Cypher endpoints."

"Breaking distributed systems so you don't have to. Jepsen is a Clojure library. A test is a Clojure program which uses the Jepsen library to set up a distributed system, run a bunch of operations against that system, and verify that the history of those operations makes sense. Jepsen has been used to verify everything from eventually-consistent commutative databases to linearizable coordination systems to distributed task schedulers. It can also generate graphs of performance and availability, helping you characterize how a system responds to different faults. See jepsen.io for examples of the sorts of analyses you can carry out with Jepsen."

" A golang library for building interactive prompts with full support for windows and posix terminals. "

"Unlike most client libraries dealing with HAL REST APIs, Hybind provides a high-level approach similar to what Object Relational Mapping (ORM) frameworks are for databases. When using Spring Data REST in the server, it is amazing how the amount of code to write is reduced to a minimum. However, a significant amount of repeated boilerplate is still required in the JavaScript client to manipulate the resources and map them to the client-side model. That's why this library exists. It enriches plain JavaScript objects with a convenient API so that performing REST requests is as easy as calling methods directly on the model objects. It is optimized for Spring Data REST, but should work with other HAL APIs following similar conventions."

"An open source electronic trading library for the JVM"

"Cascalog is a fully-featured data processing and querying library for Clojure or Java. The main use cases for Cascalog are processing "Big Data" on top of Hadoop or doing analysis on your local computer. Cascalog is a replacement for tools like Pig, Hive, and Cascading and operates at a significantly higher level of abstraction than those tools."

"Ning-compress is a Java library for encoding and decoding data in LZF format, compatible with standard C LZF package."

"LibLZF is a very small data compression library. It consists of only two .c and two .h files and is very easy to incorporate into your own programs. The compression algorithm is very, very fast, yet still written in portable C."

The Eventsourced library adds scalable actor state persistence and at-least-once message delivery guarantees to Akka. With Eventsourced, stateful actors: - Persist received messages by appending them to a log (journal) - Project received messages to derive current state - Usually hold current state in memory (memory image) - Recover current (or past) state by replaying received messages (during normal application start or after crashes) - Never persist current state directly (except optional state snapshots for recovery time optimization)

"ScalaTags is a small XML/HTML construction library for Scala. The core functionality of Scalatags is less than 200 lines of code, and yet it provides all the functionality of large frameworks like Python's Jinja2 or C#'s Razor. It does this by leveraging the functionality of the Scala language to do almost everything. A lot of different language constructs can be used to help keep your templates concise and DRY, and why re-invent them all yourself when you have someone else who has done it before you."

"Scala.Rx is an experimental change propagation library for Scala. Scala.Rx gives you Reactive variables (Rxs), which are smart variables who auto-update themselves when the values they depend on change. The underlying implementation is push-based FRP based on the ideas in Deprecating the Observer Pattern."

Spire is a numeric library for Scala which is intended to be generic, fast, and precise. Using features such as specialization, macros, type classes, and implicits, Spire works hard to defy conventional wisdom around performance and precision trade-offs. A major goal is to allow developers to write efficient numeric code without having to "bake in" particular numeric representations. In most cases, generic implementations using Spire's specialized type classes perform identically to corresponding direct implementations.

ShareJS is an Operational Transform library for NodeJS & browsers. It lets you easily do live concurrent editing in your app.

"The Cloudera Development Kit, or CDK for short, is a set of libraries, tools, examples, and documentation focused on making it easier to build systems on top of the Hadoop ecosystem. The goals of the CDK are: Codify expert patterns and practices for building data-oriented systems and applications. Let developers focus on business logic, not plumbing or infrastructure. Provide smart defaults for platform choices. Support piecemeal adoption via loosely-coupled modules."

"Scaldi - is Scala dependency injection library. Basically Scala already have everything you need for dependency injection. But still some things can be made easier. Goal of the project is to provide more standard and easy way to make dependency injection in Scala projects consuming power of the Scala language. "

"Library for expressing quantities and units of measurement in Scala in a type safe manner, where the compiler checks that assignments and calculations with the units are correct."

"The Neo4j Scala wrapper library allows you the Neo4j open source graph database through a domain-specific simplified language."

Metrics is a Java library which gives you unparalleled insight into what your code does in production.

A simple query library for scala and the Google data store.
