  • Cuneiform Digital Library Initiative (CDLI)

    Science and medicine

    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.

  • 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.

  • MalariaGEN

    Science and medicineNew in 2026

    MalariaGEN is a global network of global partners who share and integrate data relevant to inform malaria surveillance, our mission is to generate insights and tools that bridge the gaps for analysts in malaria endemic settings to use their data meaningfully to inform public health efforts. We build and optimise data resources and analytical tools to run directly in the cloud. Our flagship project is the Vector Observatory, which includes whole-genome sequence data for over 30,000 mosquitoes, integrating data from 70 partners across the globe from over 17 different mosquito species -- this is the largest resource on genetic variation data for any multicellular organism (other than humans!). Our goal is to enable analysts, scientists, students and public health practitioners to access these data without the need for any dedicated compute infrastructure, by optimising our resources to run within free compute environments (a big shout to Google Colab!) and by developing training resources that support partners to get confident with using cloud-native data and resources for their analysis.

  • MDAnalysis

    Science and medicine

    MDAnalysis is a Python library for the analysis of computer simulations of many-body systems at the molecular scale, spanning use cases from interactions of drugs with proteins to novel materials. It is written by scientists for scientists and is used for cutting edge research in biophysics, chemistry, soft-matter physics, and materials research around the world in academia and national research labs. MDAnalysis strives to be highly interoperable and hence a growing number of projects use MDAnalysis as their foundational library or integrate it.
