Chelsea Troy on the Importance of Access and the Impact of Teaching
Some of you may recognize Chelsea Troy from her popular blog of the same name or as a keynote speaker for the March 2021 Code BEAM conference. Chelsea is an instructor in the Master's Program in Computer Science at the University of Chicago and currently works as a staff software engineer at Mozilla, where she specializes in machine learning and backend systems. In our conversation with Chelsea, we discuss some of the unique aspects of coding as a career. Chelsea outlines how programming can be more accessible than other careers because it doesn't have the same financial burden when it comes to education. She also emphasizes the importance of allowing a more diverse range of people access to the field and unpacks the type of person the internet was originally built for, explaining how it had favored privileged affluent individuals from the Bay Area. We hear from Chelsea about how she became a programmer out of a desire for job security rather than passion and why she believes it’s so important to have a broader representation of different narratives when it comes to careers in programming and coding. Later Chelsea shares the story of how she became an educator and why she is so passionate about teaching. For all this and much more, join us today!

Testing Elixir with Jeffrey Matthias and Andrea Leopardi
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.

The Controlled Magic of Oban with Parker and Shannon Selbert
While there is magic to be found in many frameworks, having too much going on under the hood without you being able to control it is not for everybody. Today we invite Parker and Shannon Selbert to speak about their dynamic partnership and the ‘controlled magic’ of their tool Oban. Together Parker and Shannon founded Soren, where they help clients with established web apps stabilize, scale, and ‘add schmancy features’. Their tool Oban is a persistent background job processor written in Elixir whose differentiating feature revolves around keeping jobs after they're processed. We dive right in with Parker and Shannon hearing about how they got into programming before they talk about Oban and what sets it apart. Next up we get into how our guests navigate their personal relationship and professional partnership and they weigh in on homeschooling kids, writing new features, and the necessary life skills for handling Oban user support. Moving onto the topic of the BEAM, we explore the unique type of magic it offers and how this plays into some of the cooler features of Oban such as being able to cancel jobs. Our guests talk about some of the kinks they still need to work out of their tool and we wrap up our conversation on the pro version of Oban and how successful it has been. As always we close today’s show off with our mini-interview, this time with Joe Peck from Spreedly!
Key Points From This Episode:
The illicit stories behind how Parker and Shannon got into tech.
Understanding Oban, a persistent background job processor written in Elixir.
How Oban is different from other job processors like Sidekiq.
The great partnership our guests have and the story behind Soren.
How Parker and Shannon differentiate their personal and professional life.
The approach Parker and Shannon take to handling Oban user support.
Perspectives on the magic of homeschooling, relationships, and Oban!
Different kinds of magic provided by different frameworks and why Elixir magic is the best.
How Parker and Shannon got interested in Erlang, BEAM, and Elixir.
The best part about maintaining an open-source project.
The story behind getting a global concurrency lock on handling batches.
Added features that come with upgrading to the pro version of Oban.
Canceling a job on Oban and the role the BEAM plays in allowing this.
Writing documentation for Oban and our guest’s plans to make video tutorials.
The shift in digital learning more towards video tutorials.
Perspectives on whether we have arrived at a golden age in computing yet.
Challenges around implementing seamless horizontal scaling in Oban.
Making a living and working on Oban; advantages of setting up a pro version.

Adopting Elixir Finale with Sean Lewis, Anna Neyzberg, and René Föhring
Season 5 ends with a bang as we welcome back Sean Lewis, Anna Neyzber, and René Föhring onto the show to share their journey on getting their companies and teams to adopt Elixir. We open our conversation with each guest sharing their first experiences with Elixir. After chatting about the changes that they’ve seen in the Elixir ecosystem, we explore Elixir’s benefits and how they’ve persuaded companies to make the Elixir leap. From zero downtime deployment to arguing for Elixir’s ability to solve immediate problems, we touch on the most convincing reasons for stakeholders to adopt Elixir. Following this, we unpack common Elixir criticisms before looking at the importance of hiring developers for their aptitude as well as for their skill set. Later, we discuss what we most appreciate about Elixir, with each guest sharing a story from producing an Elixir app. We round off an insightful episode by talking about Elixir accessibility and the top ways to train entry-level programmers. Join us as we wrap up this season for a last deep-dive on adopting Elixir.

Jenn Gamble on Data Science, Machine Learning, and Elixir
The fields of data science and machine learning are moving ever faster. Jenn Gamble has her finger on the pulse and has become an industry expert with a wealth of experience to her name. As today’s guest, she dives into these rich and often complex topics, and she helps us boil them down into palatable nuggets of knowledge. We start off by asking Jenn about her current role at Very, and she tells us about the nature of her team and the things they’re able to achieve. She touches on what the language markups look like for a data science team, before moving onto her experiences in machine learning and data science. Delving deeper, Jenn tells us why it is not a necessity to have a master’s in data science, and why you can be well enough equipped in other senses to become proficient in the area. Later on, she reveals the differences between Elixir models and data science models. Following these detailed explanations, she furnishes listener’s minds with informative comments on relating the foundations of machine learning to IoT, using priori knowledge to add nuance to your machine learning, and how she envisions the future of data science. Join us today and be sure to get all this, and much more!
