Pharo
Pharo, short for Pharo Smalltalk, was created in 2008 as a fork of the Squeak Smalltalk project by Stéphane Ducasse, Damien Cassou, and a team of contributors. Pharo is a modern, open-source, object-oriented programming environment and language that focuses on live programming, dynamic development, and software research. It is used for software engineering, web applications, research prototypes, education, and embedded systems.
Docker
Docker, short for Docker Engine, is a platform for developing, shipping, and running applications using containerization technology. Originally released in 2013 by Solomon Hykes and the team at dotCloud, Docker allows developers to package an application along with its dependencies into a single, portable container that can run consistently across environments.
