  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.

  Infrastructure and cloud

  Our goal is to streamline the process of scaling and deploying machine learning (ML) models to production by leveraging Kubernetes' strengths: <br /><br /> - Seamless deployments: Effortless, repeatable, and portable deployments across diverse infrastructure, allowing you to experiment on local machines and then seamlessly transition to on-premises clusters or the cloud. <br /><br /> - Microservice management: Efficient deployment and management of loosely-coupled microservices for building modular and scalable ML pipelines. <br /><br /> - Dynamic scaling: Automated scaling based on demand, ensuring optimal resource utilization. <br /><br /> User-centric design: Recognizing the diverse tool preferences within the ML community, we prioritize user customization (within reasonable boundaries). Our system takes care of the repetitive tasks, freeing users to focus on the core ML challenges. <br /><br /> Starting focused, expanding rapidly: While we initially focused on specific technologies, we actively collaborate with various projects to integrate additional tools and broaden our reach. <br /><br /> Our vision: A future where simple manifests empower you to utilize a user-friendly ML stack anywhere Kubernetes runs, with self-configuration capabilities based on the deployment environment.

  Liquid Galaxy project

  Data

  Liquid Galaxy is a remarkable panoramic system that is tremendously compelling. It started off as a Google 20% project to run Google Earth across a small cluster of PC's and it has grown from there! Liquid Galaxy hardware consists of one or more computers driving multiple displays. Liquid Galaxy applications have been developed using a master/slave architecture. The view orientation of each slave display is configured in reference to the view of the master display. Navigation on the system is done from the master instance and the location on the master is broadcast to the slaves over UDP. The slave instances, knowing their own locations in reference to the master, then change their views accordingly. The Liquid Galaxy Project, while making use of Google Earth software, does not develop the Google Earth code-base itself. Google Earth is not open-source software, although it is free (as in beer). Instead, the Liquid Galaxy Project works on extending the Liquid Galaxy system with open-source software both improving its administration and enabling open-source applications, so that content of various types can be displayed in the immersive panoramic environment. Artificial Intelligence focus: 2026 is the year when AI is going to change the coding industry, and GSoC and the open-source projects on it, have to jump on. At the Liquid Galaxy community, we’ve been using AI for years to obtain data to be shown on Google Earth for our projects, using many models and technologies. This 2026, all the projects will have an Artificial Intelligence voice, and most of them will use of diferent AI models to handle queries and arrange data, starting from Google's Gemini and Gemma.

  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.
