This document discusses using GitHub in academic environments. It begins by asking how universities can become more open. It then defines what GitHub is and explains how it has changed collaborative open source models by making forking the norm and turning code writing into a social experience. The document notes that GitHub delivered on the theoretical promise of open source collaboration. It discusses what open source does well, like ubiquitous reuse of software components. It concludes by noting current collaborations around code, teaching, and data on GitHub, and that remaining barriers to its use are primarily cultural not technical.

23. GitHub delivered on a
theoretical promise of open
source

24. Open source collaborations
Open Source: the right to
modify

25. Open source collaborations
Open Source: the right to
modify, not the right to
contribute.

26. Open source collaborations
Forking a project was done
as a last resort

27. Open source collaborations
GitHub made forking
the norm

30. What does
Open Source do well?

31. Open Source: Ubiquitous
culture of reuse

32. Software composed of many
components

33. Your software is the thing
that is different

34. Open Source:
Verification & Metrics

42. What’s happening today?

43. Collaboration around code

47. Collaborative authoring

50. Collaborative teaching

54. Collaborative data collection

62. Barriers are (mostly) cultural,
not technical

63. Thanks.
