ElixirConf 2020 Preview
With ElixirConf 2020 just around the corner, today’s episode is a sneak peek where we talk with six of this year’s speakers. Each speaker gives listeners an elevator pitch of their talk while throwing in extra details about who their talk is aimed at, what they learned through the process, and which talks they’re excited about attending. Our first guest is Quinn Wilton, a developer at Tinfoil Security, whose talk is titled ‘Type-Safe LiveView with Gleam’. Quinn explains how she’s created a symbiosis between Elixir and Gleam that helps her create more consistent code while offsetting the disadvantages of dynamic typing. We then chat with Dan Lindeman whose talk, ‘Short Circuit IoT Development Time with Nerves,’ is an overview of building custom hardware using Nerves and Elixir. After Dan’s plug on how you can start programming Nerves on your laptop, we welcome Jeffrey Utter to the show. His talk is a deep dive into ‘Debugging Live Systems on the Beam.’ Teasing out the topic, we discuss inefficiencies in the debugging process and how many developers adopt a ‘whack-a-mole’ approach to dealing with bugs. From debugging to UintSet, Luciano Ramalho, our next speaker, gives us a taste of his presentation, ‘UIntSet: enumerable, streamable, understandable.’ Luciano shares how the Go language inspired him to experiment with leveraging protocols and streams to build new idiomatic Elixir data structures from scratch. He also touches on the importance of being humble when learning new languages and gearing Elixir to a non-engineer user base. After Luciano, we’re joined by Melvin Cedeno, a fellow Elixir Wizard from the SmartLogic family. Melvin brings his teaching experience to bear on the topic of ‘Teaching Functional Programming with Elixir.’ This is a key talk in growing our community, especially when considering the point that being an Elixir genius doesn’t necessarily mean that you’re well-suited to teach it. Last but certainly not least, we speak with Japa Swadia from Podium about her talk, ‘Domain-Driven Design with Elixir’ — a subject that’s been a huge focus on the podcast. We chat about what domain-driven design means and why it’s an important foundational concept for beginners to learn. Tune in for this tip-of-the-iceberg preview. It’s just a glimpse into the varied and wonderfully informative talks you can expect at ElixirConf 2020. Key Points From This Episode: Introducing Quinn Wilton who is using Gleam to interact with Elixir. How being acquired by Synopsys has given Tinfoil Security access to greater resources. Balancing the advantages of Elixir with its drawbacks when it comes to dynamic analysis. What Gleam is and how it makes static typing more approachable. Teasing Quinn’s ElixirConf talk — ‘Talk Type-Safe LiveView with Gleam’ What Quinn has learned from the process of creating his presentation. Building a dissembler and the talk that Quinn is most looking forward to attending. Dan Lindeman’s work at Very making solar micro-grids. The benefits of Elixir and Nerves when building custom hardware. Who Dan’s talk is aimed at and why it’s appropriate for any experience level. Working with smart minds and laboring through hardware docs that often lie. How scary it can be to work with hardware and the value of having your talk appeal to entry-level Elixir users. Jeffrey Utter unpacks his talk — ‘Debugging Live Systems on the Beam.’ How most people play ‘whack-a-mole’ when dealing with live system bugs. Using match specs to hone in on your debugging process. Why most Elixir coders should learn about Jeffrey’s debugging system. Why is Recon Library is such an excellent tool and its potential uses in distributed systems. Hear which talks Jeffrey is looking forward to attending. How Go inspired Luciano Ramalho to explore applying different data structures to Elixir. What skill-level Luciano’s talk is aimed at and why. Developing a sense of how Elixir is idiomatic, despite being such a new language. Being humble when learning new languages and the importance of protocols in understanding idiomatic data structures. How Elixir is geared towards engineers which can create barriers of entry. Mark Cedeno gives an elevator pitch for his talk — ‘Teaching Functional Programming with Elixir.’ Why knowing Elixir very well doesn’t mean that you can teach it. The benefits of remote learning; it can make your teaching more organized and to-the-point. Hear about the talks that Mark is excited about attending. Japa gives us a crash-course on domain-driven design. Creating a solid foundation for your app by considering the contexts in which it’s used. Why beginners or those wanting to switch to domain-orientated coding should attend Japa’s talk. Using schema to point to the same table in different contexts. Which talks Japa is attending and how she got selected for ElixirConf 2020.

Mark Windholtz on Domain-Driven Design (DDD)
Domain-driven design and extreme programming can help bridge the gap between development and business, and today we invite Mark Windholtz from Agile DNA to talk about how! Mark starts out by telling us about his early work in extreme programming before agile was a term and how he switched from Rails to Elixir after realizing its power for implementing domain-driven design. We take a deep dive with him into what these concepts mean, hearing him weigh in on how DDD can help architecture accommodate both development and business oriented complexities. For Mark, development and business teams must get a better understanding of each other’s jargon, and DDD is a way to accomplish this. The goal is to find a way of building a solid software core and to move away from features to systems thinking, whereby flexible software can make it more possible to do agile on the business side. We chat about some of the practices and principles that come into play when implementing DDD for Mark, and he details concepts like ubiquitous language, bounded contexts, and how to focus on the core domain by exploring models using tactical and strategic patterns. Along with this, Mark discusses users not being a domain concept, the challenges of getting new terms to stick in teams’ minds, and the task of refactoring code to reflect updated glossaries. Near the end of our conversation, Mark drills down on how DDD can optimize team efficiency. In closing, we get to know Chris Bell from ElixirTalk a little better in this week’s edition of Pattern Matching with Todd! Key Points From This Episode: Thoughts on SpaceEx and their approach to engineering: system versus feature optimization. Mark’s background in extreme programming, how he got started with AgileDNA, and the work they do there. A definition of extreme programming that adds engineering practices to Scrum. Elixir’s superior ability to do DDD compared to Rails and how Mark got started using it. A brief introduction to domain-driven design, an approach to simplifying complex software. How architecture needs to accommodate essential as well as accidental complexity. Elixir’s ability to accommodate the building of domain models with well-separated code chunks. Principles of ubiquitous language and bounded contexts that make up DDD for Mark. Ubiquitous language helps devs and businesspeople understand each other. Bounded contexts: ‘Within this space, this world means this thing.’ Shifting focus from trying to make not all software, but core software, good. What patterns are applied to use principles of ubiquitous language and bounded contexts. Finding and focusing on the core domain by exploring models and how to do this using tactical and strategic patterns. The consequences of users not being a domain concept which demands having a clearer language. Challenges of getting language and concepts to stick in business people’s minds. Refactoring code to reflect updated glossaries: Technical challenges teams doing DDD face. Switching paradigms from feature-based optimizations to building an amazing code core. Approaches to modeling: the value of exploring multiple models. How teams can become more efficient using DDD and extreme programming. Final plugs from Mark and how Agile DNA can help use Elixir to implement DDD. Pattern matching: Todd gets to know more about Chris Bell from ElixirTalk. How Chris got into programming, what he’d do if not be a programmer, and more! Why Chris loves history, dream pop, and what movie he’ll watch over and over. What project Chris is most excited about next: Building Settlers of Catan using LiveView.

Greg Mefford on Nerves, Poncho vs Umbrella Apps, and Pre-Code Planning
In today’s episode, we chat about system architecture, Ruby, Elixir, and everything in between with Greg Mefford, the senior back-end engineer for the Bleacher Report. We open the conversation by asking Greg about his start in coding, leading to a story about how Greg was that bored kid pressuring a math teacher to teach him QBasic. He shares how he fell in love with Ruby before discovering Elixir and Nerves. Having faced some challenges when learning Nerves, Greg talks about how he began documenting his pain points and writing documents to help onboard newcomers. We discuss Greg’s work with Nerves, his project aspirations, and his recommended resources for anyone looking to get into Nerves or Elixir. After providing his hot take on the latest Code BEAM V conference, we ask Greg what system architecture means to him. From there we get super meta about the meaning of architecture and what it means to translate design into practice. We touch on the struggle of understanding domain-driven design and Greg’s approach to pre-code planning before delving into how the Bleacher Report is set up. As Greg goes into details, you’ll hear why their servers now run on Elixir and not Ruby. Near the end of the episode, we talk about Poncho versus Umbrella apps, and Greg shares his passion for multi-user dungeons (MUDs). Tune in to learn more about Greg and his role in the Elixir and Nerves landscape. Key Points From This Episode: Greg’s start in coding and his transition from electronics design into IT. Why Greg loves Ruby and how he discovered the magic of Elixir. Greg’s contribution to the Elixir and Nerves community by helping onboard newcomers. What Greg’s job as a senior engineer for Bleacher Report looks like. Greg recommends resources for beginners getting into Nerves and Elixir. Creating a kid’s game using Nerves and Greg’s Blinkchain library. Greg’s take on the Code BEAM V conference and hating on the Whova app. What architecture means to Greg. This one gets deep. How translating designs into software has changed over the years. Why Greg struggles with the idea of domain-driven design. The state of Extreme Programming practices and how they synergize together. How Greg views pre-code planning; something that’s become his specialty within his latest job. The many elements that contribute to how the Bleacher Report’s IT is set up.

Johanna Larsson on Hex Diff, Domain Driven Design, Umbrella apps, and more
Johanna Larsson is a community-minded software engineer whose project, Hex Diff, generates highlighted git diffs, right in your browser. In this episode, we talk to Johanna about how Hex Diff can benefit Elixir users, the differences between code architecture and code design, and the debatably under-appreciated role of Elixir umbrella apps. We start the conversation by chatting with Johanna about her recent move to London and her work for Duffel; a startup helping travel agencies book trips. After talking about how she got into software development, we dive into Hex Diff versus GitHub, with Joanna detailing how Hex Diff offers greater security for your code. We ask Johanna about the origins of the Hex Diff project and she explores its aims and her experiences working on the project. In line with this month’s theme, we discuss what architecture means to Joanna and the need for domain-driven design. We quiz Joanna on her approaches to problem-solving and she explains how her coding process emphasizes building an early prototype and constantly iterating on it. Despite hearing that umbrella apps are bad news, Joanna makes a case for their value while acknowledging how that they need greater tooling. We round off our conversation by asking Joanna how she tries to grow her skillset and what her favorite Elixir resource is. Following our discussion with Johanna, we open with another edition of Pattern Matching with Todd. This week, friend of the podcast Todd Resudek asks five questions of Elixir community member Bruce Williams. They talk about Bruce’s work as an Arabic cryptologic linguist for the US Airforce, his software career, and the therapeutic uses of playing Animal Crossing during a pandemic. Key Points From This Episode: We introduce Johanna Larsson and she shares how she is doing in London. How Johanna developed a love for software and how Elixir brought her to London. Details about Johanna’s job at Duffel; a startup that helps travel companies book trips. How Hex Diff is solving problems that arise when using code from GitHub. Johanna’s experience working on Hex Diff and the problems that they aim to solve. Hex Diff’s caching system and what Hex Diff does to counter malicious software uploads. The disconnect between system architecture and implementation. Johanna’s view on the differences between code design and code architecture. Why domain-driven design increases usefulness to the end-user. How Johanna approaches a problem and her steps when building code. Hear what key lesson Johanna learned from her latest big project.

Ben Marx on the Launch and Architecture of SubSpace
Joining us on the show for this episode is Ben Marx, author of Adopting Elixir and Principal Control Plane Engineer at the recently launched SubSpace! We continue our Season 4 journey into system and application architecture with Ben and he unpacks what he can about the somewhat still under wraps work at the new company. Ben is all about plain-spoken and easy to understand conversations on these topics, preferring to avoid highfalutin and confusing terms with multiple interpretations. He really drills down on his understanding of the fundamentals of his work and we also get to hear about his previous position at Bleacher Report. He unpacks the lessons he took away from the company, and the changes he witnessed while there. Ben explains how Elixir fits into the work at SubSpace and what a perfect fit it is for their low-latency service. We also spend a bit of time talking about life as an introverted programmer, attending conferences and meeting people, and remote work and family life during the pandemic. For all this and then some, tune in today! Key Points From This Episode: * Ben's exciting new position at SubSpace, and how the company reduces latency. * The increasing need for more reliable internet speeds during the pandemic. * Use of Elixir for SubSpace and how well it fits the needs of the company. * The engineering team at SubSpace and some of the basic system architecture. * Meeting people, giving talks and life at conferences as an introvert. * The meaning of architecture to Ben; more dynamic than static. * Differentiating between architecture and design; the abstract and reality. * The idea of domain-driven design what the concept means to Ben. * Placement of the authentication and authorization systems. * Ben's time working at Bleacher Report and the development of the company during his time there. * Thoughts on Kafka and its baffling name! * Ben's new role at SubSpace and major areas of learning for him so far. * Adapting to a new role during the work from home era; life under quarantine. * Project management and helpful processes for remote work in a new world. * Ideas for another book from Ben, his belief in Elixir and getting in contact!
