Teaching Scala: “How do we help people answer a question if they don’t know it exists?”

If you teach Scala, chances are you face a number of questions around mentoring engineers that are new to the language. With our all-star panel of  experienced Scala educators and teachers—ranging from academia to industry, in-person education to massive online courses—we’re inviting you to join the discussion Teaching Scala: A Roundtable Discussion on June 20th at Scala Days in New York and get a new perspective on teaching Scala to beginners. Together we’ll discuss past mistakes, lessons learned and how we can most effectively teach Scala.

In advance of the panel discussion, we spoke to the panel participants Ryan Tanner (Twitter), Mark Lewis (Trinity University), Li Neville (Spotify) and Maciej Gorywoda (Wire) about their Scala experience.

Konrad ‘ktoso’ Malawski at Scala Days: “With more type-safety, Akka will bring understandability to distributed systems.”

One of the first Scala adopters in Poland, Java Champion, member of the core Akka team at Lightbend and the citizen of the world (currently based in Japan), Konrad ‘ktoso’ Malawski is on a mission to make entering the Akka ecosystem and “using the right tool for the right job” simple and understandable, both for veterans and newcomers to Scala and Akka and distributed systems.

In advance of his talk at Scala Days, “Networks and Types — the Future of Akka”, we spoke to Konrad about his Akka journey, the biggest challenges Akka developers face today and whom he’s looking to connect with at Scala Days.

Brian Benz at Scala Days: “Scala and Akka solve important problems at cloud scale.”

A Senior Developer Advocate for Microsoft, Brian Benz wants to win the hearts and minds of Scala developers by showing them first class cloud features. He’s focused on showing  how Microsoft Azure is delivering first class IoT features for distributed systems.

In advance of the workshop, “Understanding Akka Cluster Through Raspberry-Pi Cluster Visualization”, we spoke to Brian about his developer journey and asked some questions about his workshop at Scala Days New York.
