It's mid-November and we have already met one important yearly goal: that of curating entries not edited since January 1 of the current year minus 3. Woo-hoo! Usually this task is not complete until well into December (*cough* possibly not until New Year's Eve *cough*), so I'm pretty chuffed that this work is done with weeks (weeks!) to spare.
One might think this is an impossible and/or onerous task, and indeed, someone once scoffed at the idea of its being possible, but done consistently throughout the year at the rate of 15-17 entries per week, it's very manageable. I usually queue up five entries at a time for curation.What's involved, you ask? Mostly checking all links to make sure they work and go where we expect them to, finding replacements for those that need to be replaced, adding missing links, updated ADS links to resolved links (peer-reviewed versions rather than pre-prints), downloading the most recent version of the software if necessary, and checking preferred citation information -- where available (and for all that is science, please make this info available for all your software!) -- to ensure it is up-to-date. Basically, we make sure an entry is healthy and remediate anything that needs remediation.
And now we're done for the year, woo-hoo!!

Our science depends on public digital resources, including data archives, software repositories, computational infrastructures, and catalogs. Recent actions by non-scientists have led to the loss of important digital resources in other fields, and even astrophysics assets may face uncertain futures. This poster invites astronomers to reflect on how dependent our research is on shared resources and which of these may be vulnerable to loss. It also asks what actions we can take to safeguard these resources to ensure they remain secure for the future.Download (PDF)

As of today, ADS shows that ASCL entries have over 20,000 citations, w00t! Not that citations are a perfect metric -- they definitely aren't -- but they do show the ASCL is being used and is useful for citing software, thereby allowing code authors to get credit for the computational methods they contribute to the field.
So that's the milestone: 20K citations. Now the question: Who was the first to use the ASCL to cite software? I will provide chocolate (when weather/circumstances allow) to the first person who correctly identifies the first citation to an ASCL entry (using the ASCL ID).
