Open Source: Beyond the Code
0 likes87 views
Open source comes in many forms -- not just code. This slide deck covers some paradigms where one might not expect to see much open source, and hopefully inspire new projects and contributions. Included is a personal checklist I use to determine if a project is something I want to use and contribute to.

- 9. A question occured¡ What if it could be made real? Easy: Raspberry Pi (or similar) ¨C still emulation Hard: Build it from scratch ¨C ha! Medium? What would that be¡? ¡ and could it be open source?

- 11. What¡¯s open about hardware? Hardware does come with some cost, so not technically free (as in beer). But hardware design schematics, descriptions, and documentation can be made freely available under permissive licenses. Any necessary software ( rmware, toolchains, demo code) can be provided under typical OSS licenses.
- 14. FPGAs Field Programmable Gate Arrays are composed of reprogrammable logic gates that can be con gured in the eld. The con guration is usually speci ed in an HDL (like Verilog or VHDL), and toolchains are used to transform the source into the proper physical con guration. Most FPGAs and toolchains are not open. The ICE40 FPGA was reverse engineered and an open source toolchain was built: http://www.clifford.at/icestorm/ https://github.com/FPGAwars/icestudio

- 25. Documentation Good documentation is hard to nd, and hard to write. Usually permissive Usually very open to contributions
- 26. Technical Although technical books will probably never reach the best seller list, a lot of work goes into these. Most publishers, however, don¡¯t tend towards a very open model. Permissiveness depends on publisher May require errata submission in order to contribute
- 27. Text books Part of the ¡°open education¡± movement. Often least permissive Contributions via errata

- 30. Open Education Open Education most often refers to the open and free access to educational materials and courses. Most content is licensed under somewhat restrictive licenses, and contributions are often limited (courses and textbooks usually undergo peer review).
- 31. Examples edX Open edX platform is open source Khan Academy (CC-NC-SA / MIT) MIT Open Courseware (CC-BY-NC-SA) freeCodeCamp (CC-BY-SA / BSD-3-Clause) Content Open Educational Commons (CC-NC-SA)

- 33. What¡¯s open about science? Ideally, everything, since reproducibility is key to good science. This hasn¡¯t always worked out in practice, though. Splashy results from experiments tend to get the news, but reproducibility of those results is arguably more important. Open Science aims to make data openly available, and increase collaboration between scientists, and hopefully encourage reproducibility.

- 45. Why Open Source?
- 46. Hopefully you¡¯ve been inspired to go and nd new paradigms where open principles can apply. Healthy projects can change the world! Open education empowers everyone to learn about virtually anything, and expands our range of experiences. Open hardware lets everyone build and remix technology ¨C and actually own what they build (rather than be licensed for it). Open science strives to make it easier to collaborate and verify experiments, which has the potential to expand our knowledge and make the world a better place. Open art, music, and writing has the potential to expand our creative horizons, and inspire new thoughts and ideas.
