    We're software roadies. Software Freedom Conservancy is a public charity that acts as a non-profit home for dozens of Free, Libre, and Open Source Software (FLOSS) projects. Conservancy©s charitable mission is to help improve, develop, and defend FLOSS, and we do that by providing business, legal, and administrative services to our member projects. We have the honor of working with member projects comprised of, in our humble opinion, many of the best software developers in the world. Some of our member projects develop system software so ubiquitous that it permeates virtually every part of our society©s electronics-driven lifestyle. Other member projects are redefining how software will be written and even how computer science will be taught to the next generation of developers. Still others find their niche by solving a small-but- persistent problem better than anyone else ± and attract a cult following of users because of it. And, best of all, all of our member projects release their software under a license that allows the public to study, use, improve, and share the source code. Conservancy provides all of our ªrock starº member projects with a comprehensive suite of services, and then we get out of their way to let them do what they do best: write great software for the public©s benefit.

We©ve engaged the leadership of each member project©s developer community and executed a fiscal sponsorship agreement that allows us to adopt that project as an official part of Conservancy©s corporate structure.

We must regain control! 6 What’s wrong with Apt/Yum/Pacman/etc.? Global state (/usr) that prevents multiple versions of a package from coexisting. Non-atomic installation, removal, upgrade of software. No way to roll back. Nondeterminstic package builds and maintainer-uploaded binaries. (though this is changing!) Reliance on pre-built binaries provided by a single point of trust. Requires superuser privileges. 7 The problem is bigger Proliferation of language-specific package managers and binary bundles that complicate secure system maintenance.

  • Enabling Learning by Teaching: Intuitive Composing of E-Learning Modules
    Enabling Learning by Teaching: Intuitive Composing of E-Learning Modules Alexander Berntsen Stian Ellingsen Emil Henry Flakk [email protected] [email protected] [email protected] 2nd November 2015 Abstract In an effort to foster learning by teaching, we propose the development of a canvas system that makes composing e-learning modules intuitive. We try to empower and liberate non-technical module users by lowering the bar for turning them into module authors, a bar previously set far too high. In turn, this stimulates learning through teaching. By making a damn fine piece of software, we furthermore make module authoring more pleasant for experienced authors as well. We propose a system that initially enables users to easily compose H5P modules. These modules are successively easy to share and modify. Through gamification we encourage authors to share their work, and to improve the works of others.
