Polyglot Operators, Spark Operator @ DevConf.us 19

In this talk Jiri Kremser and Mike McCune will show a library for implementing the operator pattern for Kubernetes in JVM languages. The library has been used to develop an operator for deploying and managing Apache Spark clusters in Kubernetes. The talk will also feature a live-coding demo in which you will see how easy it is to create a new operator from scratch on your own.

Blockchain Analysis @ DevConf 18

In this presentation I showed a simple way of leveraging Spark's GraphX and GraphFrames for analyzing the transaction graph of Bitcoin transactions. Real data was used.

Reactive Programming @ DevConf 16

The Reactive Extensions (Rx) is a tool for composing asynchronous and event-based programs using observable sequences. It's very powerful technique to avoid callback hell and it can be used both on the server side as well as for designing the user interfaces. It leverages the concepts from functional programming such as composable monadic functors, immutable state, etc. There are libraries for Rx to almost all modern languages (Java, .Net, JavaScript, C++, Scala, Android sdk, etc.) and the presentation will show the examples in multiple languages.

Writing an internal DSL language in Scala

Have you ever wanted to write your own programming language? Why not to start with much simpler task - writing some domain specific language. Since the Scala programming language is a great fit for creating internal DSL, we will utilize its functional nature and implicit conversions, and together we will create a fluent API in form of a DSL. Scala noob? No worries! No previous Scala experience is needed, all the techniques will be explained during the workshop. It’ll be piece of cake if you know any modern programming language.
