#Talk 1: "The Real Serverless" by Jan Pustelnik

You probably have heard the pun that serverless is just running software on another person's computer. However, I would like to show something else - "real serverless" which is running software without any servers in a fully distributed, peer-to-peer manner.
Let's discover how Scala, Akka's CRDTs and the Inter Planetary File System (ipfs) can help you build applications that can scale and work without any central point of failure.

Software Engineer at Actyx by day, sporadic Akka and Dotty projects contributor by night. Interested in how software works on low level, he does not find big frameworks appealing. This is the main reason why he loves Scala, a very expressive language that allows one to build right abstractions quickly without losing control over details. Jan is an active member of JUG Łódź and occasional conference speaker. In his spare time he loves to dust-off some old issue of computer science journal only to find out that everything has already been invented before he even was born.

Talk #2: sttp: the Scala HTTP client that you always wanted! by Adam Warski

There’s a number of great Scala HTTP libraries, however on the API side, we can do better! That's where sttp comes in: it's goal is to provide a simple, type-safe API for defining & sending HTTP requests, while leveraging battle-proven backends.

In the no-slides, purely live-coding talk we’ll go through the main features of sttp: the URI interpolator, API for building requests, decoupling request definition and execution. Plus, integrations with a variety of effect-wrapping stacks, mean you can use the same programmer-friendly API regardless if you use Akka Streams, Monix, Scalaz or Cats!

I am one of the co-founders of SoftwareMill, where I code mainly using Scala and other interesting technologies. I am involved in open-source projects, such as sttp, MacWire, Quicklens and others. I have been a speaker at major conferences, such as ScalaDays, LambdaConf and Devoxx. Apart from writing software, in my free time I try to read the Internet on various (functional) programming-related subjects. Any ideas or insights usually end up with a blog (
