WE20210717: This week in the ASCL

Advisory Committee Chair Peter Teuben participated in the MODEST-21a AMUSE workshop this past week; he gave a talk on the first day on NEMO and its relation to AMUSE. He also updated the list of codes related to NEMO, including adding ASCL links to the entries that didn’t already have them. Three new code entries were staged, and, perhaps wholly or in part because of Peter’s participation in the AMUSE workshop, six new codes were submitted to the ASCL by their authors. Nine entries were curated, and about a week’s worth of social media posts were scheduled.

SciCodes meetings were this past Thursday, so a good part of my activity this week focused on preparing for that meeting, working on tasks on the SciCodes To Do list, and doing follow-up work after the meeting. We’ve scheduled a couple of writing sprints for a paper we hope to submit to a special issue of PeerJ Computer Science for this next week, and as always, it seems, I am behind on my own writing so plan to work on that this coming week, too.

WE20210710: This week in the ASCL

This week, six notification emails were sent to code authors, fifteen entries were curated, and three new entries were staged. Associate Editor Kimberly DuPrie maintains one of our link checkers and follows up on bad links. We (and by “we,” I mean primarily Kimberly) do a lot to find sites for software that has gone missing from where it used to be, and most weeks, including this one, she writes to one or more code author asking for a good link to replace the bad.

Sometimes, a software author hasn’t realized the code’s site is down; other times, the author has changed institutions, so a previous site has been wiped out. As I’ve mentioned before, we have downloaded archive files of most of the codes listed in the ASCL; we also often download information related to these codes, including the code website’s HTML files and, where they exist, user manuals. This makes it easy for us to provide these artifacts to authors whose code sites have disappeared. Alternatively, we can create an archive file of the code and the additional information we have and offer it for download if a code author prefers to have the ASCL host the code.

Other work this week was getting a bit of collaborative writing finalized, this with SciCodes participants, and talking with Robert Nemiroff on some ideas for the ASCL’s future. I tried to attend the FORCE11 Software Citation Implementation Working Group monthly call on Tuesday, but my location on that day had no cell service and wifi that was not up to the task of Zoom, alas; fortunately, the notes from the meeting are online.

WE20210703: This week in the ASCL

ASCL editors were busy this week! We added 28 new entries, edited 19, and 5 entries were added to our staging area. Notifications were sent to 34 authors and 13 social media posts were scheduled. Forty codes were added in June, more than in any other month except one, and the June additions post has been written and will appear on Wednesday

WE20210626: This week in the ASCL

A mixed week, with a little of many usual tasks. Seven new entries were put into production; some of these were submitted by authors, and the rest were codes found by editors as part of our usual perusals of astro literature. We search for the software that enables research so you don’t have to! Four staged entries were created and eight entries curated. We also added an article (Toward Long-Term and Archivable Reproducibility) to one of our Resources pages, and had some correspondence — answering questions, exchanging ideas about the ASCL, and discussing recent articles, including the one added to Resources — that is typical for an average week.

Did you notice the link to the ASCL on the June 22 Astronomy Picture of the Day (APOD) page? It appears at the bottom of the page, just above the link for Tomorrow’s picture.

APOD links to the ASCL periodically. The tie between these two resources is Robert Nemiroff, who co-created APOD with Jerry Bonnell, and co-created the ASCL with John Wallin. This past week, APOD also carried links for the Random APOD Generator that Judy Schmidt wrote, and links to APOD sites in many world languages. Want to know more about APOD? You’re in luck! Nemiroff was a guest on a recent Space Junk podcast, talking about Faster Than Light Phenomena and the Story of APOD; give it a listen!

WE20210619: This week in the ASCL

A busy week! We added four entries to our staging area, curated eighteen entries, finished the correspondence for last month’s additions, and staged thirteen random code posts for our social media sites. This latter task took a ridiculous amount of time this week, as I ran into several entries with issues. The issues that often take the longest to solve are site links that work but no longer go to code sites, or that go to pages that describe code, but have bad links for downloading the software. And this is why “today’s random code” is such an important part of our curation work! We run link checkers (two different ones) regularly, but they don’t catch instances where the link works, but the website has changed and no longer has code information on it.

Some of the curation this past week was through our query program, as described in a previous post. As we showed in our April 10 weekly post, at that time 117 entries had not been curated since the beginning of 2018; we’re now down to 59 entries to look at by the end of this year.




The monthly SciCodes meetings were this past week (one early, one late). The group has selected top priorities out of many possible tasks for collaboration and decided on basic governance. We use these meetings to share our work through monthly presentations, and we now have talks scheduled through the end of the year, except for August! August stands alone.

ADASS Prize for an Outstanding Contribution to Astronomical Software

Awarded for the first time in 2020, the Astronomical Data Analysis Software and Systems (ADASS) Prize for an Outstanding Contribution to Astronomical Software is awarded every year at the annual conference. Eligible candidates are the developers of astronomical software ranging from those that have stood the test of time to those that are new and cutting edge. Depending on the software and the nomination, the award is given to either a group or an individual. Nominations can be for a single program, a package, or a library.

Nominations for this year’s ADASS Software Prize are due by midnight UTC on June 15th June 18. After that date, the Program Organizing Committee (POC) will review the nominations and descriptions and determine the winner. The winning software author, or a representative of the winning team, will be invited to give a talk at ADASS this year, have their ADASS conference fee waived, and receive a plaque.

WE20210612: This week in the ASCL

A mix of usual work on the ASCL this week, with two author-submitted codes assigned ASCL IDs and one new code entry added, three staged entries added, and twenty entries curated. We also released the list of codes added in May and sent emails out to nearly all authors with codes added in May; we still have a few emails to go. A surprising number of authors wrote back with kind words, which ASCL editors really appreciate! (Thank you!) A couple of these authors also added license and/or citation information to their repos, as we suggest in our notification messages. (Yay! Kudos to them!) We also scheduled eight random daily code posts (for Facebook and Twitter). A few members of the Advisory Committee (AC) met this week to discuss how to fill an upcoming open seat on the committee, and a later discussion floated the idea of making this an open call for nominations by the community, with self-nominations welcome and encouraged. I like this idea and will bring it up with the whole AC this week.

I did not get any writing done; I did talk about writing, however, with a colleague who has already outlined a paper to which I will be contributing. In SciCodes work, we have a schedule for presentations, thanks to Tom Morrell and members of SciCodes who have volunteered to present or find presentations. And I did make it back to my office at UMD. It apparently takes a pandemic to make me clean (and dust) my desk, or maybe it was the need to set up a new monitor. In any case, it is lovely to be back!

WE20210605: This week in the ASCL

A productive week, with nineteen code entries added, nineteen existing entries curated, and three entries staged. We also had some activity on Advisory Committee work and planning future presentations for the SciCodes Consortium. This coming week, I plan to work on papers, my own and also a collaborative effort, and ASCL editors will likely send out publication notices to authors whose codes were added in May. And I hope to finally return to working in my office at UMD; I’ve missed being on campus and seeing colleagues.
