During our last week in Boston, I was invited to give a talk in the Science on Tap Seminar. Science on tap is a fantastic iniative driven by dedicated early career researchers that organise a talk with drinks and nibbles every Friday afternoon at the Martinos Center. The talk should be entertaining and easy to follow for all researchers at the Center. It is always a highlight of the week and great to catch-up with everyone. Since I couldn’t talk about my work I did while I was in Boston, I chose a topic that is very close to my heart: How can we use open source tools and software engineering principles to create more robust, reproducible and scalable scientific workflows? It’s a shortened and updated version of the talk I gave at the Linux conference Australia 2018.
