Working towards Sustainable Software for Science: Practice and Experiences

The 2nd Working towards Sustainable Software for Science: Practice and Experiences workshop (WSSSPE) will be held in New Orleans on Sunday, November 16. The community was invited to submit short actionable papers for use in designing the workshop.

Getting a community to adopt better practices doesn’t usually happen overnight. The ASCL has looked at previous efforts to create code libraries or registries to try to find common barriers that may have inhibited widespread use of these services; the ASCL also has looked to specific management techniques adapted from business practice to encourage change. These findings and change management strategies are discussed in our #WSSSPE 2 paper.

The WSSSPE site lists all of the freely downloadable accepted papers.

A new site for the ASCL!

On Thursday, July 10, the ASCL’s new site, designed and developed by Judy Schmidt, was moved into production. Code entries are in a new, more flexible database; as a result, browsing is much more flexible, and back-end processing is greatly improved. We have retained WordPress for related content management and this blog, and the phpbb — the discussion forum — for announcements and discussion of individual codes.

I’ve embedded a presentation that highlights the major changes to the ASCL, but hope you will explore the site and click through it rather than click through the slides! Regardless of which you do, I hope you will click Leave a reply below to post your feedback and questions; please let us know what you think!

Thanks!

Changes to the ASCL

Improvements are coming to the ASCL; we don’t have a firm timeline yet but expect to have the majority of changes made well before the end of the year. The presentation below shows screenshots of the changes; we hope you like what you see.

The biggest changes are that code entries will move from the APOD discussion forum and will be housed in a new database. We have been running the new database in parallel with the existing ASCL and are getting closer to putting the new database into production. We are integrating our current technologies — this WordPress site for our general information and blog and the phpbb for announcements and discussion for individual codes — into our new infrastructure as well.

Current URLs for code entries will continue to work after implementation of the new system. We will likely be making changes in several phases, and will announce them before and after here and on our social media sites.

Please let us know what you think; thanks!
