  CRIU

  Operating systems

  CRIU (stands for Checkpoint/Restore In Userspace), is a Linux software. It can freeze a running container (or an individual application) and checkpoint its state to disk. The data saved can be used to restore the application and run it exactly as it was during the time of the freeze. Using this functionality, application or container live migration, snapshots, remote debugging, and many other things are now possible. CRIU is packaged for all leading Linux distributions and it is integrated wit lots of popular projects such as Docker, Podman, LXC/LXD, OpenVZ, runc, open-mpi and others

  FOSSASIA

  End user applications

  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.

  Kubeflow

  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.

  LibreOffice

  End user applications

  LibreOffice is a modern Free & Open Source Office suite, one of the largest open source projects, and used by millions of users worldwide. LibreOffice is compatible with many file formats like Microsoft® Word, Excel, PowerPoint and Publisher. At its heart though, LibreOffice is built around an open standard, the OpenDocument Format, as its native file format. LibreOffice is developed by users who, just like you, believe in the principles of Free Software and in sharing their work with the world in non-restrictive ways. The development of LibreOffice is supported by The Document Foundation which provides the infrastructure for the project. We believe that users should have the freedom to run, copy, distribute, study, change and improve the software that we distribute. While we do offer no-cost downloads of the LibreOffice suite of programs, Free Software is first and foremost a matter of liberty, not price. We campaign for these freedoms because we believe that everyone deserves them. Though the members of our community hail from many different backgrounds, we all value personal choice and transparency, which translates practically into wider compatibility, more utility, and no end-user lock-in to a single product. We believe that Free Software can provide better-quality, higher-reliability, increased-security, and greater-flexibility than proprietary alternatives. LibreOffice is a large project (approx. 6MLOC), which makes it interestingly complex, but at the same time, provides a place for all sorts of contribution & skills. The community behind LibreOffice is the heart of the project, without which we would not have the resources to continue developing our software. The passion and drive that every individual brings to the community results in collaborative development that often exceeds our own expectations. With tons of different roles in the project, we invite everyone to join us in our work and help us to make LibreOffice known, prosper, and accessible to all.

  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.
