  • checkstyle

    Programming languages

    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.

  • 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.

  • National Resource for Network Biology (NRNB)

    Science and medicine

    The National Resource for Network Biology (NRNB, https://nrnb.org) organizes the development of free, open-source software technologies to enable network-based visualization, analysis, and biomedical discovery. Biomedical research is increasingly dependent on knowledge expressed in terms of networks, including gene, protein and drug interactions, cell-cell and viral-host communication, and vast social networks. Our technologies enable researchers to assemble and analyze these networks and to use them to better understand biological systems and, in particular, how they fail in disease. The NRNB mentoring organization includes projects such as Cytoscape (https://cytoscape.org/), WikiPathways (https://wikipathways.org/), SBML (https://sbml.org/), SBGN (https://sbgn.github.io/) and others. This is a great opportunity to work at the intersection of biology and computing! For example, Cytoscape is downloaded over 24,000 times per month by researchers. We take mentoring seriously and are proud of our 96% success rate (https://nrnb.org/alumni.html#gsoc-tab) with former students and projects. But don’t take our word for it, read testimonials from prior NRNB students (https://nrnb.org/testimonials.html#student-tab) and mentors (https://nrnb.org/testimonials.html#mentor-tab). Find out more about the software projects being developed in coordination with NRNB at our website (https://nrnb.org). Also refer to our GSoC page (https://nrnb.org/gsoc.html) for additional resources and application tips.

  • Open Science Labs

    Science and medicine

    Open Science Labs is a global community dedicated to creating an open space for teaching, learning, and sharing information about open science and computational tools. Our community develops tools that address real-world problems and collaborates with other projects and workgroups to improve technology and create international opportunities for our community. Although our focus may seem broad, we initially prioritize supporting Research Software Engineers (RSEs) who often face computational challenges in their work. We recognize that many colleagues in scientific fields may not be familiar with programming languages, computational libraries, version control systems, databases, DevOps, and other computational tools. Therefore, we aim to provide a safe and open space for individuals to learn and share their knowledge. Our community is open to everyone, including students, professors, and industry professionals, as we believe that the challenges and technologies used in these fields are frequently similar, if not the same (in many cases).

  • Open Technologies Alliance - GFOSS

    Science and medicine

    Open Technologies Alliance (GFOSS) is a non-profit organization, with 37 Universities and Research Centers as its shareholders. Our main goal is to promote Openness. GFOSS – Open Technologies Alliance is a platform for Open Standards, Free Software, Open Content, Open Data & Open Hardware in Greece. The major Greek Universities and Research Centers participate in GFOSS – Open Technologies Alliance, while leading members of the Greek community of developers play a key role in the implementation of our policies. Through our initiatives we aspire to contribute and coordinate the efforts of groups of volunteers, public servants, university researchers and students enabling them to form the backbone of Greek FOSS development and implementation. GFOSS is one of the strategic actors for the promotion of OSS throughout Greece (see https://joinup.ec.europa.eu/sites/default/files/inline-files/OSS%20Country%20Intelligence%20Report_GR.pdf ). Many public administrations and academic institutions collaborate with GFOSS to implement open source projects and through Google Summer of Code we give the opportunity to students to actively engage in the production and the actual implementation of an open source project. GFOSS also contributes and advises on the development of various open source projects related to e-government and digital transformation in Greece (e.g. https://howto.gov.gr/ - https://forma.gov.gr/) and actively promotes the use of Open Source software and hardware in the Greek primary and secondary education through the Open Educational Technologies Competition (https://openedtech.ellak.gr/ )
