The Ceylon Computer Science Institute (C2SI) conducts research in various domains, including security, artificial intelligence, mobile applications, cloud computing, and software tools. Our research aims to create computing solutions by identifying low-cost methodologies and strategies that promote sustainability. Currently, C2SI is at a pivotal stage in its evolution, having secured high donor confidence, as evidenced by multiple foreign-funded projects. The institute focuses on developing sustainable computing solutions that leverage low-cost computing and communication technologies, particularly for developing and emerging regions worldwide. We have developed several affordable and sustainable ICT solutions, with a special focus on the needs of the developing world. These solutions are briefly described in the projects section.
The cBioPortal for Cancer Genomics is a resource designed to provide broad community access to cancer genomic data. It provides a unique user-friendly and "biology-centric computational user interface", with the goal of making genomic data more easily accessible to translational scientists, biologists, and clinicians. The interface was explicitly built and continues to evolve with careful usability studies involving multiple biological and clinical users, and an active and engaged user base.
CERN-HSF (High-Energy Physics Software Foundation) is the umbrella organization for high-energy physics-related projects in GSoC. The HEP Software Foundation (http://hepsoftwarefoundation.org/) facilitates the coordination of common international efforts in high-energy physics software and computing.
Checkstyle is a development tool to help programmers write Java code that is easy to read and adheres to a coding standard. Our utility automates the process of checking Java code to spare humans of this boring (but important) task. This makes it ideal for projects that want to enforce a coding standard. Each and every check also forces our users who are not familiar with these standards to read them and makes them think about why these standards exist.
The Cuneiform Digital Library Initiative (CDLI) is a global collaboration of Assyriologists, museum curators, and historians working together to make the world’s earliest written records accessible online. CDLI focuses on cuneiform inscriptions dating back to the very beginning of writing around 3350 BC. Today, more than 500,000 such artifacts are held in museums and private collections worldwide, and CDLI has already digitally catalogued over 350,000 of them, helping researchers and the public explore humanity’s oldest written heritage.
DBpedia is a crowd-sourced community effort to extract structured information from Wikipedia and make this information available on the Web. It allows for a global and unified access to Knowledge Graphs.
The Debian Project is an association of Free Software developers who
volunteer their time and effort in order to produce and maintain a completely free
operating system Debian. Since its launch, the Debian project has grown to comprise more than 1,000 members with official developer status, alongside many more volunteers and contributors. Today, Debian encompasses over 50,000 packages of free, open source applications and documentation.
The Eclipse Foundation provides our global community of individuals & organizations with a mature, scalable, and business-friendly environment for OSS collaboration and innovation.
FOSSASIA is an organization developing Open Source software applications and Open Hardware together with a global community from its base in Asia. It is our goal to provide access to open technologies, science applications and knowledge that improve people's lives. We want to enable people to adapt and change technology according to their own ideas and needs and validate science and knowledge through an Open Access approach. FOSSASIA was established 2009 by Hong Phuc Dang and Mario Behling. We organize and participate in conferences, meetups and code camps. The annual FOSSASIA Summit is one of the top tech events in Asia. Other summits take place in Vietnam, Cambodia, Thailand and India. FOSSASIA also runs a number of coding programs such as Codeheat. Please join us and start contributing to our projects, participate as a coder, designer, hardware developer or event organizer.
The Global Alliance for Genomics and Health (GA4GH) was formed to help accelerate the potential of genomic medicine to advance human health. It brings together over 400 leading genome institutes and centers with IT industry leaders to create global standards and tools for the secure, privacy respecting and interoperable sharing of Genomic data.
Machine learning and Artificial Intelligence techniques can be broadly applicable and transferable across many domains. The goals of HumanAI projects are to grow the open-source community in machine learning for the domains of the Arts, Social Sciences and Humanities in addressing various important societal challenges and introducing and transferring the knowledge and tools of machine learning across these disciplines.
The International Neuroinformatics Coordinating Facility (INCF; www.incf.org) is an international organization launched in 2005, following a proposal from the Global Science Forum of the OECD.
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.
U.S. IOOS is a national and regional partnership working to provide ocean, coastal and Great Lakes observations, data, tools, and forecasts to improve safety, enhance the economy, and protect our environment. Our primary purpose is to provide free and open data about the state of our oceans and Great Lakes to our users. These data are fundamental to understanding the health of our marine ecosystems, to monitor the climate signal as captured in oceanographic conditions, and to provide predictions about the future state of our oceans and coasts.
