LSST will generate a revolutionary dataset, but the responsibility, pleasure, and burden of turning it into science belongs to the “public”, i.e. the scientific community, all of the scientific community in the US, since the LSST data will be public to all US scientists.

Light Echoes -- the reflection of stellar explosions on interstellar dust, Light Echoes appear in the sky as faint, extended, variable features ; will be entirely missed. Generative models can address this low signal-to-noise regime computer-vision problem in with a limited training set.

lessons learned
engaging the community is hard heart breaking work
200 members. interacting with ~30
even the obvious must be said
code of conduct
how to write a CoC
The BEST IS THE ENEMY OF THE GOOD
our imput is always partial, at time biased, never as good as we want them to be
LESS TALK MORE (hacking) aCTION
hackathons and task forces
Engage! as a software maker you have a homE in the SCience Collaborations

01) who is your instrument's community?
02) how many users does your instrument have, and how is this metric tracked?
03) how is communication with the user base conducted, and at what frequency?
04) what efforts are made to expand the user base?
05) what are the bibliometrics for your instrument over time (citations, citations to citations, honors, etc)?
06) how often is an article published/distributed that describes new capabilities?
07) what offshoots or spinoffs from the main software instrument have arisen?
08) who is the developer community?
09) what is the developer model?
10) how are new developers attracted?
11) how are developers retained?
12) what efforts are made to build a diverse developer base?
13) what has been the historical funding profile for your instrument?
14) what current funding efforts are underway or on the near horizon?
15) offer a definition of "sustainability" for your instrument.
16) what efforts have/are being made to reach this definition of sustainability?
17) will your instrument be widely used by your community in 10, 20, 40 years?
