Hydra - High performance parallel testing plugin for Gradle
A Gradle plugin and companion server application that aids in running tests in parallel across a cluster of servers. Hydra relies on Gradle and a CI environment to run the tests. Hydra itself consists of a backend server and a client. The backend is responsible for maintaining a database of test execution time and calculating test partitions that have similar execution time. The client is responsible for communicating with the backend and limiting a test run to the calculated test partition.

The ideal use case for Hydra is for cases where a single CI server is overwhelmed when trying to run tests in parallel. We use Hydra for one of our integration test suites that relies heavily on test databases.

skopeo - Work with remote images registries, retrieving information, images, signing content
A command line utility that performs various operations on container images and image repositories.

skopeo can work with OCI images as well as the original Docker v2 images.

Skopeo works with API V2 registries such as Docker registries, the Atomic registry, private registries, local directories and local OCI-layout directories. Skopeo does not require a daemon to be running to perform these operations which consist of:

Copying an image from and to various storage mechanisms. For example you can copy images from one registry to another, without requiring priviledge.
Inspecting a remote image showing its properties including its layers, without requiring you to pull the image to the host.
Deleting an image from an image repository.
When required by the repository, skopeo can pass the appropriate credentials and certificates for authentication.

Jolie Programming Language - Native microservice programming
The first language for Microservices. Jolie crystallises the programming concepts of microservices as native language features: the basic building blocks of software are not objects or functions, but rather services that can always be relocated and replicated as needed. Distribution and reusability are achieved by design.

Jolie is a service-oriented language. Built for the networked age: distributable by design. Jolie code is always contained in services, which you can always move from being local to remote and vice versa, without altering the logic of your programs. A monolithical application can scale to being distributed by design: if you decide to distribute a part of it, just take it and execute it in another machine.

C3 makes it easy to generate D3-based charts by wrapping the code required to construct the entire chart. We don't need to write D3 code any more.

C3 gives some classes to each element when generating, so you can define a custom style by the class and it's possible to extend the structure directly by D3.

C3 provides a variety of APIs and callbacks to access the state of the chart. By using them, you can update the chart even after it's rendered.
