Perspectives in Research Software Special Session at AAS 229

FRIDAY, 6 JANUARY 2017
Special Session: Perspectives in Research Software: Education, Funding, Reproducibility, Citation, and Impact
10:00 am – 11:30 am
Grapevine 2

The Moore-Sloan Data Science Environment at NYU and the ASCL have organized a Special Session at January’s AAS. The session, Perspectives in Research Software: Education, Funding, Reproducibility, Citation, and Impact, will be moderated by Bruce Berriman (IPAC, Caltech/Astronomy Computing Today). The session will feature short presentations and will include a discussion period with the floor open for questions and comments, and maybe even a few answers, too. The topics and presenters are :

Tracy Teal (Data Carpentry), Software not as a service
Michael Hucka (Caltech), Finding the right wheel when you don’t want to reinvent it
Lior Shamir (LTU), Reproducibility and reusability of scientific software
Ivelina Momcheva (STScI), Funding research software development
Heather Piwowar (ImpactStory), Capturing the impact of software
David W. Hogg (NYU), The relationships between software publications and software systems
Alice Allen (ASCL), Update on research software citation efforts

That last speaker looks a wee bit dodgy, but the moderator and other panelists are aces! And you, software authors and users, are as always important participants in the discussion. I hope to see you there!

OpenCon2016 Day 0

I’m attending OpenCon2016 (#OpenCon) in Washington, DC this weekend; this is a meeting of people from around the world who are improving access to data, software, and educational materials for better science, research, and education.

Tonight was an informal reception at the conference hotel. I picked up my badge from Nicole Allen and Brady Yano, and immediately got into conversation with Cody Taylor from the University of Oklahoma Libraries, where he is an Emerging Technologies Librarian. His work includes working with professors to make textbooks open access to reduce costs. Kristofferson Culmer, a PhD student in computer science at the University of Missouri and also President of the National Association of Graduate-Professional Students (NAGPS) joined us. This is Kristofferson’s third OpenCon; as Cody and I are both OpenCon newbies, our conversation included a bit of Q&A about the conference itself.

After leaving Cody and Kristofferson, I walked over to a small group of people that included Erin McKiernan, a physics professor at the National Autonomous University of Mexico and whose tweets frequently appear in my Twitter feed, and my target for walking in that direction, Peter Murray-Rust, a chemist at the University of Cambridge. Peter and I had exchanged tweets when we were both in Portland at Force2016 this past April — not that I remembered that initially — and I’ve been following him ever since. I had a reason for seeking him out tonight, as in my earlier conversation, I learned that Peter has a content mining tools that might help the ASCL: ContentMine. Yes! I cannot wait to start using it! We also talked about the state of data representation in chemistry and astrophysics and how closed chemistry is, with theses embargoed in some universities for five (!!) years. (Wow!)

I had a great conversation next with Thomas Hervé Mboa Nkoudou; he is studying Scholarly Communication at Université Laval and is from Cameroon, where he started a school. He’s very interested in science and in promoting research done in Africa and Haiti, and in the maker movement in education. We also talked about astronomy education. After that, I met Daniel Himmelstein from the University of Pennsylvania and Vinodh Ilangovan from the Max Planck Institute for Biophysical Chemistry, with whom I lamented my apparent inability to find Jon Tennant, the one person I actually expected to meet tonight!

This is a conference of mostly young people — grad students and early career — who have amazing (quite daunting!) accomplishments and are working hard to make knowledge more accessible. I am really looking forward to the next two days! I’m participating, too, with a two-minute presentation on Saturday on the ASCL, and an unconference session on Sunday on encouraging software release and citation.

First look at software activities at AAS 229

Though we have a way to go before January’s AAS meeting (and ADASS and OpenCon on the ASCL’s schedule coming up sooner), a look at the schedule for the AAS meeting already shows multiple options for the computationally-inclined astronomer. I’m very excited about the Special Session we’ve organized with the Moore-Sloan DSE, called Perspectives in Research Software. Bruce Berriman (IPAC, Caltech/Astronomy Computing Today) will moderate the session. In keeping with previous sessions, the session will include a discussion period with the floor open for questions and comments; we want to hear what you have to say. We have a panel of seven speakers; the presenters and topics are:

Tracy Teal (Data Carpentry), Software not as a service
Michael Hucka (Caltech), Finding the right wheel when you don’t want to reinvent it
Lior Shamir (LTU), Reproducibility and reusability of scientific software
Ivelina Momcheva (STScI), Funding research software development
Heather Piwowar (ImpactStory), Capturing the impact of software
David W. Hogg (NYU), The relationships between software publications and software systems
And me, Update on research software citation efforts

I hope to see you there!
