A few posts this week this an academic flavour; a survey looking into continuous integration practices and a collection of papers and research around resilience engineering. One of the things I’ve definitely noted over the years I’ve been curating the newsletter is the continued interest in devops topics in the academic community. It’s interesting and much appreciated.
