  • JdeRobot

    Other

    Robotics applications are typically distributed, made up of a collection of concurrent asynchronous components which communicate using some middleware (ROS messages, DDS...). Building robotics applications is a complex task. Integrating existing nodes or libraries that provide already solved functionality, and using several tools may increase the software robustness and shorten the development time. JdeRobot provides several tools, libraries and reusable nodes. They have been written in C++, Python or JavaScript.

  • 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.
