It is important to us that the Elixir community keeps thriving, and one of the best ways to ensure this is by lowering the barrier to entry as much as possible. Livebook is helping to achieve this aim, and today we are lucky enough to be joined by its developer, Jonatan Kłosko. Jonatan is a young prodigy because while he is still at college, he is working closely with José Valim at Dashbit, and he can solve a Rubik’s cube in under five seconds! After hearing about his college thesis on evolutionary algorithms using Numerical Elixir, we jump into the story of how he met José and started building Livebook. He explains that Livebook is a web application for writing interactive and collaborative code notebooks for Elixir and we hear about the many features he is building into it. From there, Jonatan describes what he loves about Elixir, and we discuss how learning functional programming changes the way we code.

While we can think of many reasons why we love Elixir, the community could always benefit from a more lively conversation around testing. It was with this in mind that Jeffrey Matthias and Andrea Leopardi decided to write Testing Elixir, and today they join us on the show to share some of the insights to be found in their new book. Our guests start by sketching out the main reasons why they decided to write a book of this nature before speaking to the process of writing it collaboratively from their respective homes in Italy and the US. Andrea and Jeffrey speak about the challenges of finding a middle ground between their unique styles to come up with a unified testing method. The conversation then takes a deep dive into the weeds of testing in Elixir and we hear our guests' perspectives on the most appropriate situations to use async true, Mox, Ecto Sandbox, and other techniques. We wrap up our interview with a question about what Andrea and Jeffrey would most like people to take away from their book where they express the hope that it can act as a springboard for further conversation about best practices for testing in Elixir and more. As always, we close the show off with our mini-interview, this time talking to Tracey Onim from Podii. Key Points From This Episode: Why Jeffrey and Andrea wrote their book and how they pitched it to the publisher. How the feedback Andrea and Jeffrey got while writing the book shaped its content. What writing the book was like considering its authors live in different countries. How our guests came up with a unified testing method when each had their own style. Stories about testing mistakes and the funny situations they led to. Discussing the HBO integration test email and how it was responded to and dealt with. The issue of developers not using async true enough and how to get better at it. When to use async true, Ecto Sandbox, and Mox. Why our guests use Mox, when the best times to use it are, and how it shapes your thinking. Exploring the relationship between test driven development and using the program. What can go wrong if you rely purely on tests to test out your code. The main takeaways our guests hope can be found in their book. Final plugs from Jeffrey and Andrea and where to find them online. A quick interview where we learn more about Tracey Onim from Podii.

Today’s guest is Simon Glenn-Gregg, News Engineer at The Washington Post. He joins us to talk about using Elixir to build a prototype for a platform the news house recently implemented to visualize the results of the November 2020 elections in real-time. While the job title of ‘News Engineer’ makes it seem like Simon invents news, this is not the case. He is focused on software related to publishing at The Washington Post, and in particular, has been working on building their election visualization platform for the past two years. Before the final iteration of the platform was built, the software engineering team at The Washington Post were given a period to test different technologies as an experiment to find the best fit, and Simon decided to try his hand at Elixir and Phoenix. He talks about what led him to this choice, and his experiences building out his prototype which he demonstrated on a dataset generated by the North Carolina 3rd Congressional District house race in September. Simon tells us about how the pitch went, what the team at The Washington Post was especially impressed by, and what led to the choice to use Node in the end. Simon talks about the culture of openness to new technologies at The Washington Post as well as some of the limitations to their adoption. We also hear about how the final version of the visualization platform held up during the elections proper, and Simon’s plans to include Elixir in future stacks due to its amazing abilities as far as concurrency and memory. Tune in today! Key Points From This Episode: What kinds of projects Simon works on at The Washington Post as a ‘news engineer’. The live updating election visualizer that Simon was working on at The Washington Post. What went into building the infrastructure for this platform and how Elixir was chosen as a candidate. A blog post about Elixir’s memory management; abilities Elixir has regarding concurrency. The first steps Simon took toward learning Elixir and Phoenix by building simple projects. Simon’s process of integrating his Elixir app into the current stack and people at The Washington Post. Testing the app on the 3rd Congressional District house race in North Carolina, and pitching to the team. Why it is hard to implement projects in new languages at The Washington Post. How the voting process went after the pitch and which project won. What the audience at the pitch loved about Elixir, and what the stumbling blocks were. The nature of working at a deadline-driven place like The Washington Post when it comes to adopting new technologies. Sources The Washington Post used to get their election data. What technologies and methods the team used to handle the size of data some election moments generated. Which parts about the election visualizer that ended up being built using Node would have been easier to do in Elixir. The other side of the coin – what made writing the app in Python and JavaScript easier. What future projects Elixir might be better suited to at The Washington Post. Simon’s background, education, and how he learned programming in previous jobs Why Simon stuck programming out and decided it was the right path for him. The need for software engineers at The Washington Post and why they are recruiting so often. A deep dive into the tech stack at The Washington Post and how they render their pages and maps. How Simon feels having reached the end of a successful project that millions of people engaged with. Future projects at The Washington Post and Simon’s hopes to incorporate more Elixir.

There is no difference between architecture and design. It's all engineering and creating a distinction between the two is a way for someone to get paid more and have a different title. That hot take comes from Devon Estes, today’s guest, who provides a novel way of seeing design and architecture. We open the episode by diving straight into the topic of design, with Devon exploring how good design might be less important than developing the right toolset. We then talk about how language servers can help you effortlessly define functions, meaning that in some cases, it doesn’t matter where you put your code — even if it’s all in one file. After touching on game-changing innovations in the world of design, such as GTP-3, Devon shares how our design options are limited by our editors. Considering the impact of human error on software, we discuss the value of convention and rulesets. As Elixir apps or apps that use Phoenix are open-ended, Devon talks about his middle-ground solution to help teams overcome this challenge. Near the end of the episode, Devon chats about why design and architecture, as elements of engineering, are different levels of abstraction and not separate entities. Following this, he highlights how domain-driven design can be used to avoid confusion and bugs by ensuring that people across departments all use the same language. Tune in to hear more of Devon’s unique and well-pondered insights. Key Points From This Episode: Devon’s take on design; “Where things go doesn’t matter if you have a language server.” Defining what a language server is and its incredible usefulness. How ‘go to definition’ functions could render much of design as unnecessary. Game-changing innovations that will change the world of design. Functional versus object-orientated languages and the challenge of finding files. Why Devon uses Vim and what makes it attractive to other programmers. How Elixir apps can be a challenge due to their open-ended nature. Creating primary and secondary contexts to give Phoenix more structure. The human factor; why people are often the cause of many coding issues. Hear how Devon has been structuring his Absinthe projects. Devon shares details about his Absinthe testing library, Assertions. Devon’s hot take that there is no difference between architecture and design. The importance of domain-driven design in avoiding confusion and bugs. Why engineers need to push to ensure the same language is used across departments.

Imagine being hired into a rocketship startup using Elixir as its primary language. And all this, straight out of college. Today, we speak with systems software engineer, Lizzie Paquette who works at Brex, the aforementioned rocketship. We start our conversation by talking about how Lizzie got into coding relatively late in her life, partly due to an ill-fated run-in with Java. She shares details about her role at Brex and how the company has evolved. With a love of compilers, Lizzie dives into what beginners can do to get into compiling before chatting about her top underrated Elixir resources. Following this topic, Lizzie discusses her experience liberally implementing macros at Brex — something that ended up being detrimental when onboarding new hires. After sharing how she develops herself as a professional and coder, Lizzie talks about her involvement in Code 2040, a career accelerator and mentorship program. Reflecting this season’s theme, we ask for Lizzie’s take on what architecture, design, and domain-driven design means to her. She then reveals her coding process and emphasizes the value of creating thorough design docs to avoid bugs. We explore Brex’s architecture, how it makes use of microliths, and applying ‘chaos engineering’ — a monkey-wrench approach to testing your system. We touch on umbrella apps and lessons that Lizzie’s learned from working with Brex’s architecture.

Building a sophisticated AI that can evolve to fit our vast and diverse needs is a Herculean challenge. Today we speak with senior engineer Eric Steen about Automata, his experimental Elixir project that uses neuroevolution and cutting edge theory to create a multi-agent behavior tree — or really good AI in the common tongue. But before we tap into that rich topic, we talk with Eric about tech burnout, his background, and why Elixir is an excellent language for writing modern software. He then unpacks AI concepts like the need to develop backpropagation in your system, and the value of “neural diversity,” and Markov decision processes. After Eric gives his take on architecture versus design and the place of domain-driven design, we discuss Automata. A key breakthrough, Eric shares his enthusiasm for ‘novelty search,’ where machines learn from a variety of new behaviors and searches, as opposed to completing one task at a time. We touch on Automata’s progress, Eric’s long-term approach, and what his project might be used for. Near the end of our interview, we chat about CryptoWise, a collaborative analysis platform for cryptocurrency. Todd Resudek then opens with another edition of Pattern Matching, where he interviews Whatsapp engineer Michał Muskała. They talk about Michał’s career, the movies and music that he enjoys, and the projects that excite him. Tune in to hear more about both Michał and neuroevolution in AI. Key Points From This Episode: Experiencing tech burnout and challenges around algorithms rendering you redundant. Hear about Eric’s programming background and shifts in the industry. Backpropagation and using Elixir to build a neural evolutionary system. How Markov decision processes help systems choose between possible actions. Eric’s take on architecture versus design and the place of domain-driven design. Exploring Automata — Eric’s ambitious multi-agent behavior tree. The importance of neurodiversity when building AIs; they need to adapt to many needs. Novelty search; why learn through one task when you can learn through a variety of tasks at the same time? Automata’s practical applications and why Eric sees it as a long-term project. Eric shares a progress report on his work and using design processes like Sprint. What Eric would like people to use Automata for. A sense that Elixir is gaining in popularity within Silicon Valley. Eric gives an elevator-pitch for CryptoWise, a collaborative analysis platform for cryptocurrency. Todd Resudek interviews Michał Muskała on another edition of Pattern Matching. Michał shares his background and his move from Poland to London. Movies and music that Michał enjoys, and details on projects that excite him. Differences between Erlang and Elixir and why both communities would benefit from working together.

According to an ancient myth, the world rests on the back of a turtle. And what does that turtle stand on? Another turtle. It turns out that it’s turtles all the way down. Miki Rezentes, today’s guest, believes that all software rests on the back of APIs. Similar to the myth, it’s APIs all the way down. We open our conversation by discussing how homeschooling her children did more to prepare Miki for a software career than anything else she’s encountered. Miki shares highlights from her talk, ‘APIs All the Way Down’. This set up this episode’s key theme, that the tech industry is too concerned with how its software interacts to focus on how the people in its organizations communicate — their ‘human APIs.’ Following this, we ask Miki how she learns people’s APIs and we talk about the benefits of observation and mirroring. Tracking her career, we touch on how Miki transitioned from a homemaker to a developer before diving into her recent work at the data science platform Mode. She provides unique insights into how she views architecture and design and why the concept of domain-driven design doesn’t go far enough. We chat about how you can see your team as customers to promote domain-driven design and then drill into what she does to create a ‘shared pool of knowledge’ with her team. As Miki explains, ‘people problems’ are more difficult than technical ones and developers often make mistakes by not first developing common understanding. Especially when this relates to expectations within a company. Near the end of the episode, we explore what leaders can do to maintain productivity when growing their teams. Tune in to hear what you can do to deepen your team’s pool of understanding and improve the quality of your communication. Note: this episode was recorded in late July when Miki was working at Mode; she is now a Senior Software Engineer at Frame.io (https://frame.io). Key Points From This Episode: Why homeschooling her kids better prepared Miki for software development than anything else. How people within an organization express themselves through individual APIs. Understanding that people come from different backgrounds which influence their API. The ‘shared pool of knowledge’ and figuring out how to communicate with people. Miki’s journey from homemaker to becoming a software engineer. How nobody really knows what they’re doing. Security as a trade-off, privacy, and the power of two-factor authentication. Hear about Miki’s work at the data science platform Mode. What Miki enjoys most about working in Elixir and what she uses it for. How Miki sees architecture and the differences between architecture and design. Domain-driven design and the differences between data models and software. Treating your team ‘Agilely’ and seeing them as your customers. Miki’s process of developing a shared pool of understanding before hammering out the end-to-end components. Why ‘people problems’ are much more difficult than development problems. How tech companies misdiagnose ‘people problems’ as bad design. Conway’s Law and how code production reflects an organization’s structure. The importance of setting expectations to maintain productivity as a team grows in size. The danger of the Peter principle; when people are promoted to their level of incompetency.

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.

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.

Welcome to the second part of our special Elixir Wizards Dojo. A mashup made in partnership with ElixirConf Japan. In today’s episode, we talk to Nerves core team members Todd Resudek and Connor Rigby about all things Nerves. But first, Todd leads us into a delightful digression about his enjoyment of heavy metal music. From metal back to Nerves, Todd chats about how he uses Nerves to monitor his internet connection and to automatically restart his router when certain conditions are met. After talking about using Flutter and Dart to build GUIs, we ask Todd to share another of his Nerves projects; the future of sprinklers — the Drizzle 2000! We then explore Connor’s self-defined role in the Nerves team as the development head of networking libraries before discussing how easy it is to use Nerves if you are an Elixir user. Todd and Connor dive into their utopian visions for the future of Nerves and why no other IoT solutions can compete with the tooling that Nerves provides. We talk about FarmBot and the many features that its models have, including how they can pulverize weeds. This springboards the conversion into the increasing importance of IoT tech in the agriculture sector and how it’s likely to be the next billion-dollar industry. We round off the episode by giving our guests the space to plug themselves and they close with a request for listeners to Iron Maiden and Metallica’s first albums. A perfect compliment to the first installment of the Elixir Wizards Dojo, tune in to learn more about the Nerves Project. Key Points From This Episode: Introducing our guests and this episode’s connection to ElixirConf Japan. Connor and Todd lead a chat on the history and subgenres of heavy metal music. Todd talks about using Nerves to monitor his internet connection and restart his router. Building a user interface for Nerves’s projects using Flutter; Google’s UI toolkit. Best practices for developing apps with a specific focus on GUI apps. Hear about the Drizzle 2000! Todd’s sprinkler controller system that runs on Nerves. Todd and Connor’s respective roles as a part of the Nerves core team. The benefit of using Nerves; once it’s booted it’s a regular Elixir app. What a kiosk terminal is and how you would go about internationalizing one. Exploring the future of Nerves and hardware development. Comparing Nerves to other IoT solutions; in conclusion, nothing can compete.

Although it’s taken him four seasons to make an appearance, we are so glad to finally welcome Chris McCord, creator of the Phoenix framework, onto the show. While this season’s focus is on system and application architecture, today’s discussion deviates to focus on Phoenix. We get started by hearing more about Chris’s programming journey, all the way from TI-Basic to where he is now. After this, we dive into LiveView, the project Chris is currently focusing most of his energy on. We get into some of the incredible changes that have been made including live navigation, deep change tracking optimizations, and static asset tracking. Chris shares which of the changes he is most excited about, along with why he enjoys seeing LiveView being misused. We then look at some of the critiques of LiveView and Phoenix generally. Chris offers counter-arguments to the most common criticisms of the framework.

As our first trilogy comes to a close, and we embark on the next one, we’re doing what all great trilogies do: Upending everything that made the initial one great and starting afresh. We have taken on board some excellent listener feedback to keep this the highest quality Elixir related podcast. So, for this launchisode, rather than doing a trailer, we are diving in headfirst with a full episode on system and application architecture, this season’s theme, with Justus Eapen, Dan Ivovich, and Eric Oestrich. We kick off the show by getting to know Dan and Eric a bit better. This season, as per listener requests, we will spend more time on our guests' personal lives. We learn about Dan and Eric’s time at SmartLogic, their experience working with Elixir, and their approaches to learning it. From there, we move onto tackling clients’ projects. We discuss the importance of letting ideas flow free as well as how to break projects down into manageable sized segments to work on. Following this, we touch on flexible architecture. As the world changes, sometimes at a pace faster than we anticipate, it is more important than ever to design systems that we can iterate on. Then, we discuss the future of applications and architecture and the exciting possibilities in-store. The show rounds off with our new segment, Pattern Matching with Todd, where our friend Todd Resudek gets to know someone in the community a bit better. Today, he talks with Connor Rigby of Binary Noggin, finding out more about his programing journey, his favorite music and movies, and his WiFi meshing project.

Welcome back to part two of our betweenisode! Everybody is working remotely now including ourselves, so today we continue the catch ups we were having with a number of longstanding buddies and chat about life after social distancing! The show is a back-to-back of four different conversations, the first being with Amos King, Chris Keathley, and Anna Neyzberg from Elixir Outlaws. After that we talk to Paul Schoenfelder, before getting on the line with Sophie DeBenedetto and Meryl Dakin. Last but not least we catch up with Dave Thomas. Our four conversations cover the same broad themes, and we mostly share our thoughts about what is happening in the world right now, how we are coping with working remotely, and what particular projects have been keeping us busy. Our guests share varying perspectives about what it means that we are restructuring the way we do things. We talk about how even if you worked remotely before, things feel different now, and we also consider the extra burdens of being a remote software developer. Other topics include the line between complaints and constructive criticism, wild animals roaming the streets, and the general atmosphere in our different locations. From a tech point of view, we touch on IoT development, various GitHub projects to get involved with, why students aren’t learning how to program properly anymore, and a lot more. Get it all here and make sure you stay tuned for episode one of season four! Key Points From This Episode: Scaling up the NFL Draft website for remote screening. Home life and side projects in the quarantine: Mogde Podge, a baby, and game development. Shameless plugs from everybody: Binary Noggin, ElixirBridge, and Finch. Isolation, low supplies and trying to stay positive at present. Imagining roaming wild animals now that humans are in quarantine. Advice from Paul who works at home for surviving social distancing. What Paul is doing for Ockam to secure IoT devices. The danger of starting hack vulnerable tech companies. A plug from Paul to get involved with Lumen. Nature taking over; Meryl and Sophie’s experiences in Brooklyn and Westchester right now. Working from home versus working from home due to a global crisis. Domestic squabbles over bandwidth between Meryl and her software developer brother. Lessons learned to stay sane during quarantine: getting dressed. Extra tasks remote developers are having to do remotely; becoming project managers. The difference between complaints and legitimate critiques of work systems. Dave’s amazing remote communications setup 40 miles north of Dallas. The situation where Dave is with regard to coronavirus and freedom. How COBOL has not become too broad despite not using libraries. The history of programming languages that Dave teaches. That PDP-11 runs better emulated in Javascript than in its original hardware. A drawback of modern development: not understanding hardware. How Dave is digitizing his SMU courses due to teaching them online at present. All the effort Dave puts into grading his students’ exercises. Issues that coding is not taught rigorously enough; students can’t ‘program’. How well the human race is doing to mobilize en masse right now. Whether tech caused the crisis and humanity could manage this crisis 100 years ago.

Welcome to another extra special episode of Elixir Wizards! We have guest hosts today, Meryl Dakin of Frame.io and Sophie DeBenedetto of Github, and they welcome Steven Nunez, Staff Engineer at the Flatiron School, and Sean Callan, creator of Elixir School, to the show. Where some would see the fact that Elixir doesn’t have a ton of readily available answers out there as a restriction to mastering the language, our guests argue that this is the best educational environment. Writing about challenges and teaching others how you overcame them are some of the best ways to learn. We also discuss concurrency and other contrasts with prominent languages. Our guests weigh in on dealing with students and how far enthusiasm and openness can go in helping inspire other minds. Steven stresses the need for greater resources, especially at a beginner level, as this will lower the barrier to entry for new programmers and ultimately benefit the entire Elixir community. Key Points From This Episode: An introduction to Sean and Steven, their work and experience with Elixir. Work and professional horoscopes for the panel of today's podcast! The accidental path that led Sean to Elixir and the translations that affirmed his work. The use of writing and blogging in your own education; teaching is learning twice! Steven's early attraction to Elixir and the obsession and evangelism that followed. Concurrency visibility and differences between Elixir and other languages. Different tracks for learning; coming into Elixir as a beginner or as someone with experience. The evolution of thought around education and things that have changed at Elixir School. Learning that includes reasons why; you don't know what you don't know! Knowing your students and keeping them excited to maintain a passion for learning. Growing confidence and the benefits of great resources for the spread of increasing skills. Scratching your own itch; write the educational information that you cannot find yourself. Our guest's Elixir wish lists; more learning opportunities, widespread adoption and beginner-friendly content. Requests about Elixir from our guests, a few plugs and how to connect with them!

Our guest today, Devon Estes, approached us about the possible opportunity for Elixir to optimize and build out the pandas data analysis and manipulation tool, sharing why he thinks it would be a valuable addition to the Elixir open source ecosystem. But Devon joins us to contribute to our ongoing discussion about performance and training in the Elixir world, sharing about his current work on the beta for Sketch Cloud, his previous Erlang consultancy role at one of the largest banks in Europe, and the massive responsibility he carried while working on the bottom line application. He continues to advise listeners on the considerations for optimizing Erlang performance and solving database-specific problems, and the memory constraints he comes up against in the Sketch Cloud application. Devon talks about Benchee, a benchmarking library created by his friend, and how the two of them have continued to develop this tool, including its performance testing capabilities and how they deconstructed the benchmarking steps to build out the library. He also talks more broadly about the importance of considering the data when distinguishing between facts and opinions in conversations about performance. Key Points From This Episode: What Devon believes would be a valuable addition to the Elixir open source ecosystem. Why optimizing and building out the pandas tool will be worth a company’s time and effort. Devon’s experience with pandas and Python, and recognizing the opportunity for Elixir. Working on the beta for Sketch’s Cloud that will allow real-time collaboration. Devon’s consultancy role at Klarna, one of the largest banks in Europe. The responsibility involved in working on the bottom-of-the-stack application at Klarna. Considerations for optimizing Erlang performance and why you should look at the tail. Solving the database performance problems – running queries and searches – at Klarna. The unique memory constraints of Sketch Cloud and the problem with receiving large files. More about Benchee, a benchmarking library, and all its performance testing capabilities. Deciding whether a function is responsible for other things when benchmarking. The time Devon spends on optimizing performance and the first two steps in the process. The profiling process of determining which function is slow and writing a benchmark for it. Distinguish between a fact and an opinion by considering the data (or lack thereof). Keeping in mind that truth is time-bound, and it also applies to benchmarking. Deconstructing the steps in the process of further developing Benchee. How Devon became a maintainer of the Elixir track for Exercism, and what the role involves.

In today’s episode we have one of our favorite recurring guests, Brooklyn Zelenka, joining us once again! Brooklyn has been on the show in both the first and second seasons to speak about Elixir and functional programming. In those conversations, it came up that this topic is far from exhausted, and since Season 3's theme is working with Elixir, we thought it would be great to have Brooklyn on for a third time. Today, Brooklyn does not speak to Elixir specifically though, but on functional programming more broadly. Fission, her company which is working on developing next-generation hostless apps, actually uses Haskel, but Brooklyn has a ton of experience across the board. She gives us some great insights into what makes the functional versus OOP paradigm great and helps us to understand some of the inner workings of both worlds, talking about abstraction, application, data orientation, and more. Interestingly, Brooklyn does employ some imperative programming in her company through the use of Typescript, but uses a functional style to get around the context switch. We spend some time toward the end of the show digging deeper into macros, and Brooklyn helps to revise understandings of them as code which writes more code as well as clarifies the term 'homoiconic' as it relates to ASTs. Brooklyn covers a whole lot more today so hop on for a deep dive into functional programming with today's great guest. Key Points From This Episode: • Why Brooklyn uses FPE: it can be reused and reasoned about. • Two things that functions provide: abstraction and application. • Data orientation and hiding information: imperative vs functional paradigms. • Understanding imperative programming: it’s less structured and hard to reason about. • Challenges experienced imperative programmers face with functional programming. • Differences between Elixir, Erlang, Haskel, Elm, and Clojure. • Using Clojure: tradeoffs, distinctions, tooling, flexibility, and compatibility with Java. • The language Brooklyn could use if only one existed: Racket. • Bridging functional and imperative paradigms through disciplined use of style. • Segfaults in Haskell related to its compatibility with lib C. • How to use Musl instead of lib C by employing docker files. • Algebraic types and why static types aren’t hindrances in functional languages. • Preferences for tests or proofs and their role in finding types valuable. • Macros as compile-time functions that are difficult to debug. • A definition of a ‘homoiconic’: high-level syntax which represents the AST. • What makes C macros different from Lisp ones. • Architecture in Elixir and the need for a more user-friendly Haskell.

We are happy to be joined in this episode by Eric Meadows Jönsson, creator of the hexpm package manager, and an amazing resource who works tirelessly to build the Elixir community. Eric presently works at Brex and was part of the core team at Forza previously. In keeping with our current topic of all things working with Elixir, Eric takes a deep dive into the work he is doing to optimize various interfaces at Brex. He gives us the rundown on the static compile-time checking project he is working on, talking about his aims to build in different warnings and what we can expect from the new release in that regard. You’ll also hear about Eric’s journey learning Elixir and how he had to change his OOP mindset when he got introduced to functional programming at university. He shares the story behind hexpm and Mint, his thoughts about the future of Hex, and some of the processes around accessing the private repositories on its website. We also hear more about Eric’s hiring procedure while working at Forza, how he teaches functional programming to students at ElixirConf, and some of the major performance bottlenecks he experiences using Hex. Tap into the incredible resource that is Eric and hear more about how you can link with him online to learn further in the future by tuning in! Key Points From This Episode: Jose Valim, the Ecto library, and Eric’s journey with Elixir since 2012 at a coding camp. Early-stage static compile-time checks that Eric is adding to the compiler at Brex. Whether the static compile-time checks Eric is adding constitute a type system or not. Static compile-time checks in the current system such as undefined function warnings. Features of the new static compile-time check release: refactored checks, etc. Currently, these checks happen at compile-time, or when Elixir compiles into the byte code. Whether these checks will move into BEAM: currently it’s in Elixir and at an early stage. The Erlang compiler already does type inference during compilation. Eric’s Erlang proficiency and why he had to brush up on it through using Elixir. What makes Eric helpful with Hex: his debugging skills and availability to answer questions. How Eric got started with Hex adding an intake for Git packages. The story behind Hex regarding ties to Elixir and Devinus from Pool Boy. Todd’s perspective on Eric as a smart and nice mentor who sleeps very little. Changes that Eric sees happening in Elixir. Hex will no longer support older Elixir versions so that it can enable better maintenance. Another change will be a refactoring of the resolution version algorithm. Security-related updates that Todd has been working on. Private versus public repositories on the hex.pm website. Hiring challenges at Forza and how Eric found the right team out of scarce people. Eric looks for people who love being programmers and have a passion for learning. Tactics Eric uses to train functional programming such as hosting ElixirConf workshops. Important fundamentals in functional programming: using data structures to model data, etc. Differences between functional and object-oriented programming: data vs classes. The role of types in Eric coming to understand functional programming better. Performance bottlenecks in Hex such as dependency resolution. How every package manager/resolver compromises, exemplified by NPM and Rebar3. Origins of Mint: wanting http2 support for Hex, and more.

Our guest on the show today is blogger, software cowboy, and podcast host Chris Keathley. Chris is a senior engineer at Bleacher Report, co-host of Elixir Outlaws, and writer of an assemblage of open-source software. He joins us today to speak about his new projects, his journey with functional programming, and what it is like to run Bleacher Report’s infrastructure on Elixir. Chris gives us the lowdown on Norm, a data validating interface he recently completed, weighing in on how it is different from Dialyzer and what it can offer as far as scalability. We hear more about how Chris got introduced to Elixir through Haskell, why he wishes he learned Clojure sooner, and why Ruby on Rails isn’t going anywhere soon. Chris also gets into the tradeoffs these languages make to correlate with Erlang. He argues that Elixir can only be more widely adopted if more people build cool things in it, and then lays out some of its power in supporting Bleacher Report’s user interface. We pick Chris’s brain about what his company is trying to optimize at the moment and hear about their preference for capacity over speed, and their techniques for failing gracefully during traffic spikes. Chris tells us how much he loves Elixir due to its use of ETS and other functionality which allows Bleacher Report to keep running even above capacity. Finally, we hear about some of the observability practices that Bleacher Report uses when deploying new systems and predicting future spikes. Plug in for a great conversation and hear why you should get building with Elixir now! Key Points From This Episode: Chris’s explanation of Norm, his new software that describes data moving through a system. Chris’s introduction to functional programming through learning Haskell, Clojure, and Elixir. What makes a great functional language: immutable data and first class functions. Things that make Clojure great, such as its thought out, holistic design. Characteristics of Cons lists versus RRB trees, and what makes the latter better. An acknowledgment of the necessity of the tradeoffs Elixir makes to interact with Erlang. A little bit about the language Chris wrote to do the admin of code challenges in. Why Ruby (on Rails) will not be replaced by Elixir due to commoditization that surrounds it. An argument that Elixir can only be more widely adopted if more people build with it. Why any language can build any program thus comparisons between them are arbitrary. Where Chris sets the bar as to when something is performant. Chris’s preference for high user capacity capability over speed of delivery at Bleacher Report. Optimization projects at Bleacher Report such as using few boxes and handling traffic spikes. Things Chris loves about Elixir such as its ability to deliver more from its boxes. Elixir’s use of ETS and how Chris coded a complex problem in half a day using it. How Chris detects spikes using time series, StatsD, and other observability tools.

Welcome back to the SmartLogic Podcast where we talk about the latest developments and best practices in the web and mobile software industry. In continuing with our theme of Elixir Internals, we’re having a conversation about the inner workings of one of the most popular Elixir libraries, Credo, and we are joined by the author René Föhring. René shares the story of how he was introduced to Elixir while doing his PhD and looking for a new programming language and then shares the philosophy and inspiration Credo was developed on. Wanting Credo to be a less rule-based, authoritative code analysis tool and more user friendly, René focused on creating it to act as a type of digital mentor to the many developers out there who do not have a human mentor. He also shares about some of the launching hiccups, what he would have done differently had he been given another opportunity and some of the most important lessons that he has learned working in the open source community. Be sure to join us for all the inside info! Key Points from This Episode: More about René’s job as head of product development at 5 Minds and what they do. What he does in his free time: open source maintenance and conference speaking. How he got started with Elixir and wanting to learn a new programming language. What Credo is all about, why you’d want to use it and what makes it different. The inspiration behind writing Credo and wanting a more positive, less dogmatic tool. Starting off building on Dogma but then pivoting and going in an independent direction. The hiccups René experienced when first releasing Credo and what he’d do differently. The different checks in Credo and how they function and respond to issues. How Elixir 1.6 impacted the development of Credo. What’s new with the Credo 1.1 release?

We talk with Jay Ashe from Cava about their current and past Elixir projects and how they are deployed. Jay Ashe - Cava (https://cava.com/) Find Jay elsewhere online: https://twitter.com/jgashe 0:40 - Give us a quick overview of the Elixir projects you have in production. CAVA is a fast-casual mediterranean restaurant chain with 75 stores across the US. Elixir and phoenix power CAVA’s online ordering platform (order.cava.com and the CAVA app). We’ve got a REST (and websockets) api sitting behind react and our mobile apps, and we use phoenix templates for some of our back of house systems. 1:11 - Why are you using Elixir in production? We have from the start! The application was originally implemented by Chris Bell and his team at madebymany. Chris, by the way, has a fantastic talk from ElixirConf 2016 that goes into our architecture and how we use elixir and OTP constructs to model our business logic. Chris will occasionally talk about the CAVA project on his Elixir podcast, ElixirTalk. Chris’ Talk - https://www.youtube.com/watch?v=fkDhU-2NWJ8 (https://www.youtube.com/watch?v=fkDhU-2NWJ8) 1:58 - What are some of the high level advantages / disadvantages of Elixir, from your perspective? Advantages: Elixir and Phoenix gives you rails-esque productivity/developer experience that scales. I think phoenix channels are a great example of this. Build a channel with complex real-time functionality and let it scale effortlessly. Disadvantages: Hiring and onboarding, depending on your mindset, can be difficult. If you’re used to hiring for experience in your stack, its just going to be more difficult. Lately we’ve started doing one-hour weekly knowledge shares that cover elixir basics and are closely tied to our usage of them. So, here’s a test case, and here are all of the test helpers that we have set up that will help you write that test. We also just sent a new Elixir dev to lonestar elixir 3:59 - What do you use to host your Elixir app? Heroku How do you deploy your application? Heroku-buildpack-elixir https://github.com/HashNuke/heroku-buildpack-elixir (https://github.com/HashNuke/heroku-buildpack-elixir) 4:44 - Are you able to get zero downtime deploys? - As close as possible! We get that out of the box with heroku. When we deploy, heroku won’t point traffic to the new dyno until the app is healthy. We make extensive use of Phoenix channels over websockets, and our clients will reconnect automatically and transparently. 5:10 - Do you cluster the application? Nope. 5:52 - How does your Elixir App perform compared to others in your environment? I can’t really talk about numbers here, but Elixir is not at all our bottleneck. We don’t have other production applications 6:25 - How are you solving background task processing? Quantum for cron jobs, genservers for everything else. We’re running a single elixir application that handles all synchronous and async processing 7:07 - What libraries are you using? Phoenix Phoenix_swagger for API documentation that integrates with controller tests https://github.com/xerions/phoenix_swagger (https://github.com/xerions/phoenix_swagger) Ex_rated for rate limiting calls to our integrations https://github.com/grempe/ex_rated (https://github.com/grempe/ex_rated) Timex and calendar for datetime support with timezones https://github.com/bitwalker/timex (https://github.com/bitwalker/timex) A combination of httpotion and httpoison for HTTP clients, but im interested in trying Mint https://github.com/ericmj/mint (https://github.com/ericmj/mint)https://github.com/appcues/mojito (https://github.com/appcues/mojito) Bamboo for transactional emails, like order confirmations etc https://github.com/thoughtbot/bamboo (https://github.com/thoughtbot/bamboo) 8:59 - 3rd Party Services (i.e. Email, Payment Processing, etc) Sendgrid for email, Google for geocoding, slack for some internal alerting of application health, LevelUp for payments. https://www.thelevelup.com/ (https://www.thelevelup.com/) 10:07 - Do you have a story where Elixir saved the day in production? Yes and no. So I could tell this story by explaining the issue we saw and the underlying cause at the same time, but I think it would be more fun to tell it like our team experienced it. One day at lunch our application started going down. Lots of 500 errors. Red lights flashing. Panic ensuing. Lunch is our busiest time of day, so 1) we thought it was load related and 2) we really needed to fix it None of our traditional resources (database, cpu, memory) were constrained and our integrations that were synchronous were fine. Our logs were littered with errors from an analytics integration that ran asynchronously on genservers, but it didn’t seem related because we could see the error logs at times when our application was otherwise healthy. The team that used the analytics didn’t have a pressing need for them, and we deprioritized fixing the issue because the bug we were working on was so much more important (that’s foreshadowing). I spent a little time looking at websockets, but I was easily able to match the load of the websocket portion of our application on my local machine with no degradations in performance (thanks, phoenix), so that was out. At this point the issue was going on every day at lunch and I was getting annoyed at seeing the logs from the analytics integration when debugging, so I spent like 15 minutes finding and fixing the issue (a bad API key, basically) Voila, issue gone. Time to grab some lunch. We spent a while coming up with an explanation for this. Eventually we learned about max_restarts on a supervisor. By default, if a process crashes 3 times in 5 seconds, the process won’t be restarted again. So if another process (like the one handling a web request) tries to call that process that wasn’t restarted, the caller would crash, and we’d start to get 500 errors, customers couldn’t log in, mass confusion. So there are a few takeaways from this story: For a while, elixir saved the day in production. - A supervision tree prevented failures from the analytics process from affecting customers, until the scale of our failures exceeded the max_restart level. - Our supervision tree needed some love though, clearly. - Monitor your resources. CPU is a resource, but calls to another API are also a resource and can get unhealthy too. 15:00 - Are you using any cool OTP features? GenServers, definitely. There’s lots we can do asynchronously especially in terms of our integrations. One process per store is a cool model that scales well and keeps issues isolated to a single store. 15:50 - If you could give one tip to developers out there who are or may soon be running Elixir in production, what would it be? If you’re on a small team, Heroku or a similar provider might give you a lot of value in terms of infrastructure you can set up and forget. Learn more about how SmartLogic uses Phoenix and Elixir.

(https://spade.builders/) Find Brooklyn elsewhere online: https://twitter.com/expede https://github.com/expede 1:08 - Brooklyn’s Background Brooklyn's background and experience with Elixir is deep. Huge open source contributor. Got started in Elixir just after Phoenix got to 1.0. 1:53 - Worked on several Elixir projects in production. 2:43 - Why she got into Elixir. - Real Time - More performant than Rails. - Great documentation - Industrial-grade 4:38 - When you wouldn't use Elixir. Easy to get stakeholder buy-in. Just point to WhatsApp. Elixir is made for 2019 CLI tools Repl-driven development TDD tools built in by default All the best practices we have today are built in. 7:14 - Where has Brooklyn hosted her apps? Heroku for POC's. AWS for production. Dockerized because "kubernetes is the new hotness" 9:40 - Do you do any clustering? Load balanced above. AWS load balancing is very standard. They're well understood and have a nice developer experience. 10:29 Are you able to get any zero downtime deploys? Zero downtime deploys. Awesome but impractical. Rolling deploys are easier and usually more appropriate. Some requirements make it valuable. Erlang error states. Exceptional. Allows you to build for the happy path. Don't worry about error handling all the time. Witchcraft and dark magic. Monads. Poke around the standard library. 12:50 - How does Elixir compare to Rails in terms of response times, and other aspects? 15:32 - What libraries do you use and what have you built? 22:41 - Any cool features of OTP you are using? 25:36 - One tip to developers new to Elixir Build up a peer-to-peer cli chat from scratch in one GenServer.

We talk with developers from the team here at SmartLogic about our current practices on deploying Elixir and Phoenix in production. Dan Ivovich - Director of Development Operations @ SmartLogic Learn more about how SmartLogic uses Phoenix and Elixir. (https://smartlogic.io/phoenix-and-elixir) 00:00 - Fade In 00:30 - Introductions to Eric, Dan and SmartLogic Dan Ivovich - Director of Development Operations @ SmartLogic Eric Oestrich - Developer, Elixir Lead @ SmartLogic Justus Eapen - Full stack developer @ SmartLogic Introduced to Elixir by an old colleague. 1:20 - What Elixir projects do you have in production? Several client projects in production. Several Mobile Apps with APIs powered by Phoenix and Elixir. Baltimore Water Taxi. A digital marketplace. And more! 1:57 - Advantages and disadvantages to using Elixir. We made the switch when a colleague was stoked about Functional Programming and introduced us to Elixir. We were won over by the performance and rich feature sets, OTP, etc. 2:43 - Where are we hosting our Elixir Apps? Heroku AWS Linode Digital Ocean 6:20Deployment process, tools, scripting Ansible - for underlying VPS’s, servers, and more recently deployment itself. (Similar to Capistrano). Distillery Mix.release 7:18 - Zero Downtime Deployments Old school load balancers and rolling restarts 7:46 - What are the performance metrics like? Comparatively. Ruby ends up with memory leaks. That doesn’t happen with Elixir. Memory utilization is flat and low no matter what. “Phenomenal response times” 8:54 - How does Eric think about clustered applications in Elixir? Going Multi Node (https://www.youtube.com/watch?v=lCUKQnkjajo (https://www.youtube.com/watch?v=lCUKQnkjajo)) Pg2 (http://erlang.org/doc/man/pg2.html) - process groups Mnesia (http://erlang.org/doc/man/mnesia.html) distributed database (beware!) “Just sending messages to pids because Erlang is great” Swarm (https://github.com/bitwalker/swarm) / Horde (https://github.com/derekkraan/horde) 12:40 - How do we handle background tasks? Started with verk (https://github.com/edgurgel/verk) Recently becoming more comfortable with spinning up GenServers (https://hexdocs.pm/elixir/GenServer.html) “The language itself is built to be concurrent.” 15:06 What libraries are we using in prod? First thing: You don’t need a whole lot because the language is so well designed. Phoenix (https://phoenixframework.org/) - web framework Ecto (https://hexdocs.pm/ecto/Ecto.html) - sort of an ORM Distillery (https://github.com/bitwalker/distillery) - for releases Bamboo (https://github.com/thoughtbot/bamboo) - for sending emails Quantum (https://github.com/c-rack/quantum-elixir) - for task scheduling Timex (https://github.com/bitwalker/timex) - for dates and times, and timezones Cachex (https://github.com/whitfin/cachex) - for caching 18:20- What third party integrations have we attempted Stripe Square Twilio Mindbody Always building our own clients. Using HTTPoison (https://github.com/edgurgel/httpoison) 19:58Has Elixir ever saved the day in production? It’s saved many days by PREVENTING ISSUES. Systems are architected for reliability and fault-tolerance. 21:48 - Where do supervision trees come from? What is OTP? OTP is an Erlang standard lib Includes supervision trees, genservers, ETS, and a lot of stuff we don’t even know about! gen_tcp (http://erlang.org/doc/man/gen_tcp.html) Mnesia dets (http://erlang.org/doc/man/dets.html) 23:43- Tips for devs considering running elixir in production.
