My slides from the 5-year anniversary of CCA.

Transcript

1. ASTRONOMICAL SOFTWARE a brief & biased story by Dan Foreman-Mackey
2. [today] The past, present, & future of open - source software development and support at CCA.
7. open - source (scientif i c) software? Linux < = = = > Untitled42.ipynb
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
15. [coming soon] Advanced Astronomical Software Development, a Crash Course (probably) May 9-13, 2022 @ CCA
16. SO. DOES IT WORK?
17. How do we measure the impact of scientif i c software?

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!
34. HERE’S TO MANY MORE YEARS OF SOFTWARE AT CCA!
