  International Catrobat Association

  Programming languages

  Computational thinking for all with free visual coding apps The Catrobat project develops useful frameworks to create games, animations, or apps easily within a short time. This set of mobile creativity tools for smartphones is inspired by the well-known Scratch framework by the Lifelong Kindergarten Group at the MIT Media Lab. The motivation behind the project is that programming is an important cultural technique on the same level as mathematics and physics, from a practical as well as from a philosophical point of view. Our aim thus is to popularize the skills needed to program from an early age in a fun and engaging way that will facilitate the spread of its adoption among young people all over the world.

  MetaCall

  Programming languages

  When working with different technologies and developers of different programming languages, the productivity of the entire team worsens due to the lack of interoperability and communication between them. If the developers need two technologies which are written in different programming languages, for instance, a C/C++ library called from NodeJS, the team usually needs to port to one of the two languages or write a wrapper around them. Maintaining a port of a library or the plumbing code is frequently error-prone, time-consuming, and does not add any value to the final product.

  Processing Foundation

  Programming languages

  Our mission is to promote software learning within the arts, artistic learning within technology-related fields, and to celebrate the diverse communities that make these fields vibrant, liberatory, and innovative. Our goal is to support people of all backgrounds in learning how to program and make creative work with code, especially those who might not otherwise have access to tools and resources. We also believe that some of the most radical futures and innovative technologies are being built by communities that have been pushed to the margins by dominant tech. We hope to support those who have been marginalized by technology in continued self-determination by providing time, space, and resources.
