This video was recorded at Scala Days Berlin 2016 follow us on Twitter @ScalaDays or visit our website for more information http://scaladays.org Abstract: A collection of horror stories that derive from a lack of best practices. Everything will be covered: How to make companies lose money, shutdown systems and disable payments (or worse) just from overlooking simple procedures that "take too much time" or "cost too much" to implement. We may even dim the lights at certain points in the presentation.
