ElixirConf EU Virtual October 2020

This video was recorded at ElixirConf EU Virtual 2020 - https://www.elixirconf.eu/ More great virtual tech conferences - https://codesync.global --- Can we visualize software complexity? by Rafał Studnicki ABSTRACT We all know that certain software design principles help with system maintenance. Assigning every module a single responsibility is one such principle. It’s common that these principles are only applied at early stages of development, since it’s much easier to follow good practices when the system is still in on pen-and-paper. It gets harder with a real programming language. One picture can say a thousand words. Wouldn’t it be nice if we could see an architecturial diagram of our application at any time? Not as designed, but as actually running in production. In this talk Rafał will show you how. --- THE SPEAKER - Rafał Studnicki Rafal is a software engineer with 10 years of experience in Elixir, Erlang and C. He has worked on various distributed systems, ranging from tiny clusters on microcontrollers to some of the largest chat servers in the world. Having consulted on many real-world projects, he has come to believe that clean architecture, ruthless simplicity, and a principled stance towards testing for correctness are required for software to serve its business purpose successfully in the long run. --- ElixirConf EU Website: https://www.elixirconf.eu/ Twitter: https://twitter.com/ElixirConfEU

Our speakers, doorbells, televisions, and fridges are getting smart. We are getting used to relinquishing our privacy and our lives to random startups that won’t hesitate a second to sell our data to the highest bidder. But what if we went rogue? What if we took back control? In this talk, I will explain how to replace devices over which you have no control with devices over which you have absolute and complete control. We will see how easy it is to build smart devices which are safe and privacy conscious, thanks to the powers of Elixir and Nerves. At the end of the talk, you should feel confident to go out there and build your own reliable, discreet and smart Nervous assistants. --- THE SPEAKER - Ju Liu Ju was born in China, moved to Italy as a kid, grew up eating a lot of pasta, and started messing around with computers. He now lives in London and works for NoRedInk. He loves to solve interesting problems and build amazing products.

Mint is built on the idea of having a functional, data-centric client that is not backed up by a process and doesn't impose a process architecture on its users. In this talk, we'll discuss the ideas behind Mint's design and get a feel of how Mint works. We'll spend some time exploring how the low-level interface that Mint provides lets us build different abstractions on top of it that are suited for different situations. We'll see the future of Mint and what abstractions it will enable. --- THE SPEAKER - Andrea Leopardi Andrea is a human born in the ancient lands of central Italy. He loves functional programming, beautiful code, and learning stuff. He's a software architect, speaker, and member of the core team of the Elixir programming language. His weak spot is having red hair. --- ElixirConf EU Website: https://www.elixirconf.eu/ Twitter: https://twitter.com/ElixirConfEU

Although the ecosystem is quite mature, integrating with very old systems that have non-standard practices brought us some common problems. Also, for a team new to the BEAM at first, there were other challenges like deployment practices, architectural choices, BEAM culture in general, human resources and so on. It all pays off in the end for us and we hope this sharing of experience might help others decide to participate in the ecosystem. --- THE SPEAKER - Victor Nascimento Victor is currently a technical leader of the Stone OpenBanking solution and a BEAM admirer since OTP 13 (before Elixir). Author of some widely used Elixir libraries like Joken, Joken JWKS and JUnit Formatter he is also passionate about Emacs and is one of the maintainers of elixir-mode. With a Philosophy major he usually attracts political and ethical discussions which is a curse and a pleasure at the same time. Other than family, music, skating, dogs, philosophy, programming and beer hunting he does nothing at all. --- ElixirConf EU Website: https://www.elixirconf.eu/ Twitter: https://twitter.com/ElixirConfEU
