Hand-crafted spam

Nearly every month, ASCL editors notify software authors that their code has been registered in the ASCL. Each editor sends out notifications for the code entries she worked on. I say “nearly every month” because I sometimes get behind in the prep work for the notifications, and that delays all editors who send out these notifications. Editors create their own processes for handling this correspondence.

I refer to my process as “hand-crafted spam.” I send out two types of notifications, one to authors who submitted their software to the ASCL, and another to authors for code entries I created. I have standard text into which I add, one by one, the necessary details for each email, by cutting and pasting the info from an Excel spreadsheet I create just for this purpose. I also check the emails against the ASCL entries to make sure I’ve got the right code and author. This sounds laborious, but it actually doesn’t take much time. This afternoon, I sent out 34 emails covering 39 code entries (some authors had two codes added to the ASCL) for code entries processed in February, March, and April, and it took me, working at a steady but unhurried pace, exactly one hour from the first missive to the last.

I’m putting this here to remind future me that this task goes pretty quickly, so, future me, do this more promptly!

The ASCL at AAS 243: A Special Session and posters!

The ASCL is at the 243rd meeting of the American Astronomical Society (AAS), which is taking place in the major food destination New Orleans.

Special Session: Into the Future: Building on 25 Years of Community Organization in Astro Software Development

Abstract: Over the past 25 years, astronomy has seen many changes involving research software development. These include improved transparency, improved software availability, and changes in journal policies. Formal recognition of community-based software development has increased through targeted funding, the establishment of new journals specifically focused on software, and code citation.

Changes in astro software development include the rise of open social coding sites such as GitHub and GitLab, the establishment and growth of conferences devoted to or including research software (such as ADASS, FORCE11, and the Research Data Alliance), and community-based training in software development (for example, The Carpentries and SciCoder) and exploration (for example, .dotastro and hack days) events.

This Special Session will look back at the community-driven work that has enabled some of these changes and look forward to future horizons for the software community in astronomy. Leaders of some of these community efforts will serve on an expert panel and will share their perspectives, after which the floor will be open for discussion with participants.

Abstract: The Astrophysics Source Code Library (ASCL, ascl.net) is an online registry of source codes used in refereed astrophysics research. It currently lists over 3,300 codes and covers all aspects of computational astrophysics, and all of its public metadata about software can be downloaded. This presentation covers possible ways the ASCL can be used by educators and their graduate students. The ASCL serves as a discovery tool for codes that can be used for one’s own research. Graduate students can also investigate existing codes to see how common astronomical problems are approached numerically in practice, and use these codes as benchmarks for their own solutions to these problems. Further, they can deepen their knowledge of software practices and techniques through examination of others’ codes, and can use the ASCL’s data set for research on computational methods in astrophysics.

Abstract: The Astrophysics Source Code Library (ASCL, ascl.net) is a free online registry for source codes of interest to astronomers, astrophysicists, and planetary scientists. It lists, and in some cases houses, software used in research that has appeared in, or been submitted to, peer-reviewed publications. It now has over 3300 software entries and is indexed by ADS and Clarivate’s Web of Science. In 2020, NASA created the Exoplanet Modeling and Analysis Center (EMAC, emac.gsfc.nasa.gov). Housed at the Goddard Space Flight Center, EMAC serves, in part, as a catalog and repository for exoplanet research resources. EMAC currently has 223 entries, 77% of which are for downloadable software. This presentation will cover the collaborative work the ASCL is doing with EMAC and with NASA’s Astrophysics Data System (ADS) to increase the discoverability and citability of EMAC’s software entries and to strengthen the ASCL’s and ADS’s ability to serve the planetary science community.

ASCL at ADASS XXXIII: Broken bones and improving the visibility and citability of exoplanet research software

ADASS is my favorite conference; it’s so favored that… well, you’ll see …

ADASS was in Tucson this year. I decided to drive from Maryland to Tucson, figuring that was likely my best way to avoid getting/bringing COVID to the conference. It’s too long a drive to do in one day, so I stayed at a campsite outside Claremore, Oklahoma one night. It was lovely! Almost deserted, lots of birds, view of the lake… perfect! But alas, when making my coffee the next morning, I tripped and fell, breaking my right arm and nose and bashing up a few other body parts. I got patched up at a local hospital (excellent care!) and had surgery two days later (more excellent care!). I couldn’t drive, of course, so what to do, what to do? A friend offered to fly to Tulsa and drive me wherever I wanted to go, suggesting “back home” would be best. Where did I want to go? Tucson, of course! I did not want to miss ADASS!! So off to Tucson we went. Once I was deposited in a hotel there, she flew back to her home. (Now that’s a friend!! I’m forever grateful!!)

I gave an oral presentation at ADASS on “Improving the visibility and citability of exoplanet research software,” this about the work the ASCL is doing with NASA’s Exoplanet Modeling and Analysis Center (EMAC) and ADS. Links to my slides and proceedings pre-print are below.

ADASS did not disappoint! I’m so glad I attended it, and also attended the IVOA meeting immediately after. Everyone was helpful and kind, as I knew they would be. I stayed in Tucson until cleared to drive, and then drove myself the 2300 miles home. Not the trip (hahahaha) I was expecting, but it was the trip that was.
