Event-Driven Elixir with Thomas Kunnumpurath - EMx 166
In this episode the panel talks to Thomas Kunnumpurath about how to build event-driven systems in Elixir and what tradeoffs different approaches have. The panel probes Thomas - who is a relative newcomer to Elixir but well versed in building event-based systems - on his experience with various event brokers and compares how using an event broker differs from using the BEAMs built-in distribution mechanisms. Additionally the panel provides some insight into the BEAM’s history and for which context the BEAM’s distribution mechanisms were optimized. At the end Thomas asks the panel for some suggestions on how he can continue his BEAM journey with more advanced learning material.

Learning Erlang with Adolfo Neto - EMx 165
In this episode the panel talks with Adolfo Neto who went out to learn Erlang during last year’s “Advent of Code”. He talks about his experience with the format, compares it against using a platform such as exercism.org - where mentors can give feedback - and how this shaped his perception of the onboarding experience of Erlang. The panel also discusses Adolfo’s involvement in the Erlang Ecosystem Foundation’s education working group and what they think Erlang - and Elixir - could do better to attract newcomers and make onboarding easier.

To Umbrella or not to Umbrella - EMx 162
In this episode the panel is picking up an often discussed topic in the Elixir community: umbrella projects and possible alternatives. They go over what an umbrella project actually is and their experiences with them. Based on this they go over the trade-offs you better know about, restrictions which might come back to bite you and how possible alternatives - like a monolithic app, “poncho” projects, or separate services - fare up against umbrella projects. In the end they also reflect on what has been said and give their opinions on how they’d built a complex greenfield project today.

Want to see Elixir/Phoenix out in the wild? In this episode, Allen sits down with Erik Guzmán, a developer whose proficiency in Elixir/Phoenix enabled him to created instant closed captions for both Twitch and Zoom audiences. The two discuss why Elixir is so seamless in its scaling capabilities, how Elixir’s ability to reveal errors sooner saved Erik’s behind once or twice, and the biggest lessons Erik learned from burn out. “Because of how scalable and efficient things are, every client on Twitch is able to connect directly to my servers and get captions. I’ve been able to make a richer user experience.” - Erik In This Episode Why Erik moved from Ruby to Elixir and why it’s seamless for scaling How Erik’s live streaming programming for Twitch and Zoom is changing the game for speech-to-text What Erik learned from building code manually in Elixir/Phoenix, revealing something not-so-great about Ruby on Rails How Elixir reveals errors before they become life-threatening, saving Erik from a world of hurt What getting laid off and burnt out taught Erik about streaming, programming, and sharing Sponsors Top End Devs (https://topenddevs.com/) Picks Allen’s: Cloudflare Workers: https://workers.cloudflare.com/ Erik’s Ted Lasso show on AppleTV Connect with Erik: Twitch 1 https://twitter.com/talk2megooseman Erik Guzman - DEV Community Special Guest: Erik Guzmán.
