DVDGC13 is now in mastodon.💚<p>Last talk of the session is by Connor Aird - Stop, Collaborate and Listen: how to reduce wasted RSE effort<br>He's talking about a <a href="https://octodon.social/tags/DiRAC" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>DiRAC</span></a> project he worked on last year. First task was to implement a kernel.<br>Part of the project was not version controlled, and tests that were not touched for more than 4 years.</p><p>We may prefer to change to a most modern language or bring new practices, but that's a risk from the PI perspective because will take lots for them to learn. The same way that we can't take the research forward as it would take lots of year to learn the science behind. So it's a compromise between their and ours best world.</p><p>Remember to Listen!
