Livebook's big launch week

JosĂ© Valim joins Jerod to talk all about what’s new in Livebook – the Elixir-based interactive code notebook he’s been working on the last few years.

José made a big bet when he decided to bring machine learning to Elixir. That bet is now paying off with amazing new capabilities such as building and deploying a Whisper-based chat app to Hugging Face in just 15 minutes.

JosĂ© demoed that and much more during Livebook’s first-ever launch week. Let’s get into it.

Human scale deployments

Lars is big on Elixir. Think apps that scale really well, tend to be monolithic, and have one of the most mature deployment models: self-contained releases & built-in hot code reloading. In episode 7, Gerhard talked to Lars about “Why Kubernetes”. There is a follow-up YouTube stream that showed how to automate deploys for an Elixir app using K3s & ArgoCD.

More than a year later, how does Lars think about running applications in production? What does simple & straightforward mean to him? Gerhard’s favourite: what is “human scale deployments”?

How vex.dev runs on AWS, Fly.io & GCP

Few genuinely need a multi-cloud setup. There is plenty of advice out there which mostly boils down to don’t do it, you will be worse off. Vex.dev is a startup that provides APIs for video and audio streaming. The hard part is real-time combined with massive scale - think hundreds of thousands of concurrent connections. They achieve this by using a combination of Fly.io, AWS and GCP. Jason Carter, founder of Vex Communications, is joining us today to talk about the multi-cloud setup that vex.dev runs.

A guided tour through ID3 esoterica

This week we turn the mics on ourselves, kind of. Lars Wikman joins the show to give us a guided tour through ID3 esoterica and the shiny new open source Elixir library he developed for us. We talk about what ID3 is, its many versions, what it aims to be and what it could have been, how our library project got started, all the unique features and failed dreams of the ID3v2 spec, how ID3v2 and Podcasting 2.0 are solving the problem differently, and how all of this maps back to us giving you (our listeners) a better experience while listening to our shows.

In today’s Kaizen episode, we talk about shipping Adam’s Christmas present: chapter support for all Changelog episodes that we now publish. This feature was hard because there are many subtle differences in how the ID3 spec is implemented. Of course, once the PR shipped, there were other issues to solve, including an upgrade the world kind of scenario. Since Lars Wikman did all the heavy ID3 lifting, he joins us in this episode.

Why are the right values important for a company that changed the way the world builds software? How does pair programming help scale & maintain the company culture? What is it like to grow a company to 3000 employees over 30 years?

Today we have the privilege of Rob Mee, former CEO of Pivotal, the real home of Cloud Foundry and Concourse CI. Rob is now the CEO of Geometer.io, an incubator where Elixir is behind many great ideas executed well, including the US COVID response programme.

From Kubernetes to PaaS - now what?

2022-05-04T15:45:00Z #ops +5 🎧 7,470

Today we talk to Mark Ericksen about all the things that we could be doing on the new platform - this is a follow-up to episode 50.

Mark specialises in Elixir, he hosts the Thinking Elixir podcast, and he also helps make Fly.io the best place to run Phoenix apps, such as changelog.com. In the interest of holding our new platform right, we thought that it would be a great idea to talk to someone that does this all day, every day, for many years now.

We touch up on how to run database migrations safely, and how to upgrade our application config to the latest Phoenix version. We also talked about some of the more advanced platform features that we may want to start leveraging, like the multi-region PostgreSQL.

We’ve been using Parker Selbert’s Oban library for years and he even helped us hold it right by improving our open source implementation!

So, Jerod invited him Backstage to discuss the library, how we’re using it, Parker’s plan to make it financially sustainable, his “freedom number” of Oban Pro subscribers, and a bunch of other random stuff along the way. Let’s go!

Why Kubernetes?

This week on Ship It! Gerhard talks with Lars Wikman (independent Elixir/BEAM software consultant) why sometimes a monolith running on a single host with continuous backups and a built-in self-restore capability is everything that a small team of developers needs. That’s right, no Kubernetes or microservices. After 2 years of running changelog.com, a Phoenix monolith, on Kubernetes, what do I think? Join our discuss and find out!

Today we’re sharing a special crossover episode from The Changelog podcast here on Practical AI. Recently, Daniel Whitenack joined Jerod Santo to talk with JosĂ© Valim, Elixir creator, about Numerical Elixir. This is José’s newest project that’s bringing Elixir into the world of machine learning. They discuss why JosĂ© chose this as his next direction, the team’s layered approach, influences and collaborators on this effort, and their awesome collaborative notebook that’s built on Phoenix LiveView.
