 Sometimes called "The JQuery of DataTypes": Lenses and other Optics provide a clean functional interface to the common task of modifying complex data structures. Brushing over any practical use cases, this talk takes a magnifying glass to one particular Optics representation: van Laarhoven Lenses. We'll explore how building a van Laarhoven-based Lens Framework may require some of the lesser known Functors, and see if Lenses can shine a new light on how we think about Abstraction.

+# Jacob Wang: Practical Type Safety
+
+What is type safety? Why should we care? What techniques are possible to improve type safety in my Scala code? should I use them?
+
+Whether you're a beginner or already familiar with Scala,
+this part-philosophical, part-practical will empower you to write better code, and be happier writing them too!

+# Lucio Biondi: Authentication & role-based authorisation for http4s microservices
+
+While developing REST micro-services, and http4s is a good choice to this end, one of the many challenges every team has to face with sooner or later is how to control access to the resources the system provides. This is of course a sensitive topic from a security standpoint, so public and complete implementations from which to draw inspiration are not easily found on the Web.
