Guarantees and Intent in Software Development

Rickard's talk will present a look into the differences between intent and guarantees in code, as well as how we can express them and leverage them to stay on track while building software.

Lazy Interactions - Back to the Future

This talk will show us how to build interactive programs in Haskell using the core features of modern functional languages: higher-order functions, pattern matching, data types, and lazy evaluation. This approach was first used in Miranda in the late 1980s, and Simon will reflect on what has changed - and what hasn't - in functional programming between then and now.

What Should Error Handling Be Like?

Whenever the happy path meets the real world, those edge cases and exceptions inevitably come up. There are tons of ways to handle errors, and people like to roll their own. Let's take a look at the fundamentals and reason our way towards choosing a better error-handling abstraction with the tools at hand, be it in C or Purescript.

Elixir in a Nutshell

Learning a new programming language is always a challenge, especially if you deep dive into concepts like immutability, scalability, concurrency and fault tolerance. Elixir manages to handle all of them and then some, yet somehow making it seem easy. So let's look into Elixir and everything you need to know about it.

The Promised Backend Land

This talk will be about Phoenix LiveView, which provides rich, real-time user experiences with server-rendered HTML. What does that mean, is it needed, and what makes LiveView different from the alternatives in other languages? These are some of the questions that this talk will provide an opinionated answer to.

Functional Programming as a Career (Elixir and Beyond)

15 years ago functional programming was just an academic toy for most of us, especially here in Bulgaria. Requirements and priorities change with time as we live in a very concurrent world now which leads to functional ideas like immutability, reactive and data driven systems that are highly available, as data becomes more mainstream.

Nikolay will talk about fields that are interested in more functional-like programming, data streaming, concurrent connections and updates, parallel computation and the ease we can achieve with Elixir/Erlang. He'll also share his own experience with the changing programming world and why he chose Elixir as his main tool for problem solving.

Implementing a Blockchain Peer Node in Erlang

Erlang is a programming language used to build massively scalable soft real-time systems with requirements on high availability. It runs on the BEAM virtual machine. A peer node has a lot of different components - ex. consensus, mining, networking and peer discovery and communication. Dimitar and his team have also built their own smart contract virtual machine. Some other hard requirements are determinism and portability. In this talk, Dimitar will share his experience with all of those running on the BEAM.

FP Survival in the World of Java

How can we turn things around and bring functional programming concepts in frameworks written in Java for Java decades ago? Kotlin and arrow-kt come to the rescue! We'll try to trace the evolution of Kotlin support in the Spring ecosystem and how we can leverage functional libraries like arrow-kt to make our code a joy to work with.
