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.

To close off this season and conclude our deep dive into system and application architecture, today’s episode is a special panel discussion on a topic that has provoked a mix of answers that range from the controversial to the philosophical — “What does domain-driven design mean to you?” For the final word on this subject, we welcome back software developers Chris Keathley, Japa Swadia, Mark Windholtz, and Miki Rezentes. Our first hot take comes from Miki, who shares her thoughts about how domain-driven design developed because the tech industry undervalues communication. Following this, Mark and Japa discuss how domain-driven design gives developers a context for what they create while informing how you code using Elixir. We then touch on whether domain-driven design makes it easier or more difficult to change your code and how communication is valued within a business context. We explore key domain-driven design concepts, including the role of bounded contexts, and how this design ethos can help you appeal to stakeholders such as product managers. After Miki highlights the reasons why communication should be seen as a vital tech skill, each guest provides their final thoughts on domain-driven design.

Even with the most programming experience in the world, coding still involves a lot of trial and error. People getting started in the industry should not become bogged down by failure. Because in the end, it’s a feature and not a bug. That’s one of Zillion developer Anna Sherman’s key messages this episode. We open our discussion with Anna by talking about living in Chattanooga, AKA, Gig City. She talks about why the tech scene there is exploding before diving into her journey into programming. Having created her own personal coding boot camp, she opens up about what she did to land her first software job within only two months of looking. After discussing her early working experiences, we explore her work at Zillion, along with her side projects. We then touch on what Anna does to expand her skillset and develop herself as a professional, using a style guide and ‘lunch and learns’ to update her team, and we hear the elevator pitch for Anna’s Code BEAM San Francisco talk. Anna shares her take on architecture and design, as well as the importance of domain-driven design in keeping your team aligned with what they’re building. Near the end of the episode, we talk about Anna’s pre-coding process, the virtues of being a ‘physlistcler,’ and why failure is an important part of coding. Tune in to hear more of Anna’s insights on change, failure, and living in Gig City. Key Points From This Episode: Fast internet and the great outdoors; hear why Chattanooga has become a tech hub.
