Sugar on a Stick is a Fedora-based operating system featuring the award-winning Sugar Learning Platform and designed to fit on an ordinary USB thumbdrive ("stick"). Originally developed for the One Laptop Per Child Project and designed specifically as a 1-to-1 computing environment for K-8 students to collaborate with others in exploring the world around them, Sugar is used every day by over one and a half million students in classrooms throughout the world. It is now deployable for the cost of a stick rather than a laptop; students can take their Sugar on a Stick thumbdrive to any machine - at school, at home, at a library or community center - and boot their customized computing environment without touching the host machine’s hard disk or existing system at all.

The heart of the Sugar Learning Platform is its Activities for children - fun and engaging programs for reading e-books, writing, drawing, browsing the Internet, programming, and so on. Each Activity is designed to achieve specific pedagogical goals.

A thriving community-created ecosystem of Activities can be found at the Sugar Labs Activities Portal. Activities take full advantage of computer-based learning, from interactive speech synthesis for beginning readers to tools for remixing open content into customized digital libraries for your local classroom.

Sugar automatically saves your progress to a "Journal" on your stick, so teachers and parents can easily pull up "all collaborative web browsing sessions done in the past week" or "papers written with Daniel and Sarah in the last 24 hours" with a simple query rather than memorizing complex file/folder structures.

The source code for each Activity is available right from the application itself with the "View Source" feature, meaning that students can see exactly how their favorite applications work - and perhaps how to make them even better. Tinkering encouraged! An international community of learners, teachers, deployers, and developers is always there to help classrooms turn their feedback and ideas for improvement into reality.
