Elixir Mix

Today we talk with Louis Pilfold, an ex-elixir/Lang developer.  Since 2018, Louis has been working on Gleam, and hesitantly admits to being its author.  This statically typed language that runs on Erlang virtual machine and draws its inspiration from several other languages.  With Gleam gaining a lot of traction, it’s definitely worth a look into this up and coming gem.

In this episode of the Mix the panelists talk about Seniority. They lay out their own personal journeys towards getting a senior title and how they define seniority for themselves - especially how it goes beyond the ability to write code well.

Among other things they discuss:

• how to become fluent in reading and writing code
• how side projects are useful but not required to become a great developer
• how senior developers tend to approach problem solving and how to get better at that
• how interpersonal skills play at least an equal role as technical knowledge
• how specific tech know-how becomes less and less important the further developers climb the ladder - at least the managerial ladder
• how organizational structures cannot be ignored when building solutions

They close with some picks which they deem valuable for anybody who'd like to dig deeper into some of these ideas.

In today’s all-panelist episode, we take a shot at demystify domain-driven design.  We discuss several books and some concepts that stand out in those texts.  How easy or hard do Elixir and Phoenix make it to apply DDD principles?  We give our experience with taking these concepts and putting them into practice, and give some tips and resources for getting started.

Some of the topics covered:

• Tactical vs. strategic domain-driven design 
• Event Storming
• Bounded Contexts
• Accidental vs Intentional complexity

In this episode the panel talks to Danny Hawkins - CTO at Quiqup - and his team's journey at Quiqup with Elixir. Danny explains how some of the first things Quiqup built were using Elixir and how they then left Elixir behind in favor of TypeScript, only to come back to Elixir.

The panel considers how these choices rarely are purely driven by technological qualities but instead have to factor in cultural- and knowledge-aspects of a team, and how a top-down dictated technology decision - even if there are good reasons for it - can be harmful to a team's morale.

In this episode Adi and Sascha dig deeper into what it means to consume and build APIs in Elixir and how a RESTful approach compares to choosing GraphQL as your weapon of choice. Along the way they discuss common pitfalls when building APIs (spoiler: one is caching), how to test all of this, and what their personal preferences and experiences are in creating APIs in Elixir.

Bad documentation wastes time, costs real money, and makes developers unproductive.  Documentation might be bad because it is flat-out wrong (typos, references to an older version, etc.), but more often documentation is bad when it fails to tell us what we need to know.  Don’t let all your hard work go to waste because you failed to communicate what your software is or how to use it.  Today on the show, Everett Griffiths shares his insights on how to approach documentation simply and effectively.

In this episode…

1. What got you into documentation?  
2. Examples, examples, examples
3. Having an effective feedback loop
4. Key word arguments
5. Coding is easy, but documentation is hard
6. Using mermaid charts
7. Open sourcing your software
8. Clean code and clean infrastructure 
9. Simplifying coding environments
