[today] The past, present, & future of open - source
software development and support at CCA.

open - source (scientif i c) software? Linux < =
= = > Untitled42.ipynb
a selection of some* CCA-supported software: and some open -
source meta projects: * my apologies for neglecting your favorites!
[here at CCA] We have a lot of shared expertise
[here at CCA] We support software that is: [1] Useful
(often broadly) [2] Easy to use [3] Well - tested & documented
[here at CCA] We have the privilege of developing methods/libraries/etc.
without being in service to a specif i c project
[here at CCA] We have a responsibility to share what
we have learned

[coming soon] Advanced Astronomical Software Development, a Crash Course (probably)
May 9-13, 2022 @ CCA
SO. DOES IT WORK?
How do we measure the impact of scientif i c
software?

GREAT! SO WE’RE DONE?
Is the astronomical software ecosystem sustainable? 1
Many fundamental software packages have a shockingly small number of
maintainers.

Many fundamental software packages have a single point of failure.
What is the career trajectory for a software developer in
astrophysics? 2
2
A lot of useful open - source software is produced
by astronomers who don’t have the expertise or capacity to maintain it. 3
We have an opportunity to def i ne CCA’s role
in this: [education] [consulting] [support] […]
[here at CCA] Some opportunities: [1] Hiring [2] Presenting shared
values [3] Building & supporting communities [4] More!
HERE’S TO MANY MORE YEARS OF SOFTWARE AT CCA!
