  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).

  openSUSE Project

  Operating systems

  The openSUSE Project is a worldwide effort that promotes the use of Linux, tools around it, and open source. The openSUSE community is made up of multiple contributing communities that collaborate as part of a global open-source network. The openSUSE community develops, builds and maintains many of the packages, tools and infrastructure for the distribution. The community works together in an open, transparent and friendly manner as part of the global Free and Open Source Software community. openSUSE creates one of the world's best Linux distributions, as well as a variety of tools, such as OBS, OpenQA, Kiwi, YaST, OSEM and Uyuni. Distributions include a rolling release (Tumbleweed), a stable annual release (Leap) and operating systems for edge, embedded, cloud and containers through MicroOS and ALP.
