Peter Saxton

Elixir developer (Pay with Curl)

As a regular participant in hacknights and meet-ups in London, Peter is always learning something new.He is keen to share his latest insights and has written and presented on the topic of Domain Driven Design. Currently, Peter is enjoying seeing how DDD concepts merge with the rigor of functional languages.

Mind your own business View Controller (ADVANCED)

Many applications are a perfect fit for Model View Controller(MVC). There are also many applications where MVC is not suitable. In both cases Elixir is a great choice. This talk will be a guide for alternative architectures e.g Hexagonal/Onion/Clean.

OBJECTIVES

In this talk Peter will review some ideas for designing software. Ask what separation of concerns really means? Discuss how to use the tools we have to organise our code, such as mix, umbrellas and releases. Finally, he will ask some questions about what more the Elixir ecosystem needs to reach its potential?

Message passing for actors and humans with Raxx (INTERMEDIATE)

Elixir, and Erlang, implement an elegant model of message passing. This is their secret sauce for managing concurrency.

HTTP is the primary means of communicating between clients and servers, and often between servers and other servers, it is a protocol for message passing.

Raxx is an Elixir toolkit that treats HTTP interactions as just another kind of message. These external messages are handled in a way completely analagous to internal messages between processes.

This talk will start with an explanation of the core concepts and getting started with Raxx.

Extending message passing to all parts of a system provides a uniform model to describe it.

This talk will explore how to use this model to reason about interactions in an extended web application, from server to browser to human.

OBJECTIVES

Attendee will learn some basics about Elixir and it's web tools (10-15 min).

They will also learn about the Actor model and issues relating to its use, such as:

- at least/most once delivery
- request/response patterns
- race-conditions

TARGET AUDIENCE

Anyone interested in developing non trivial distributed systems

Raxx; refined web development

Raxx can be used to build web applications much like Plug. However that is where the similarities end. Raxx aims to simplify web applications by promoting simple concepts like functional purity and message passing.

I started the project in 2016. Since then, it has matured to the point where it has been used in several production services. This talk will cover an introduction to the project; an overview of the rationale behind it, and finally a vision of what comes next.

OBJECTIVES

Introduce the audience to Raxx, as an alternative to Plug in the Elixir eco-system. More generally it is to explore why functional purity is valuable in the erlang/Elixir world and how a different conceptual model can lead to a completely different solution to the same problem.
