8. a selection of some* CCA-supported software: and some open -

   source meta projects: * my apologies for neglecting your favorites!

9. [here at CCA] We have a lot of shared expertise

10. [here at CCA] We support software that is: [1] Useful

    (often broadly) [2] Easy to use [3] Well - tested & documented

11. [here at CCA] We have the privilege of developing methods/libraries/etc.

    without being in service to a specif i c project

12. [here at CCA] We have a responsibility to share what

    we have learned

24. GREAT! SO WE’RE DONE?

25. Is the astronomical software ecosystem sustainable? 1

26. Many fundamental software packages have a shockingly small number of

    maintainers.

28. Many fundamental software packages have a single point of failure.

29. What is the career trajectory for a software developer in

    astrophysics? 2

31. A lot of useful open - source software is produced

    by astronomers who don’t have the expertise or capacity to maintain it. 3

32. We have an opportunity to def i ne CCA’s role

    in this: [education] [consulting] [support] […]

33. [here at CCA] Some opportunities: [1] Hiring [2] Presenting shared

    values [3] Building & supporting communities [4] More!
