This week Peer Richelsen, Co-Founder and Co-CEO of Cal.com, joins the show to talk about building the “Stripe for Time” — with a grand mission to connect a billion people by 2031 through calendar scheduling. Cal has grown from an open-source side project to one of the fastest-growing commercial open source companies. We get into all the details — what it means to be an open source Calendly alternative, how they quantify connecting a Billion people by 2031, where there’s room for innovation in the scheduling space, and why being community first is part of their secret sauce.

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.

AI is discovering new drugs. Sound like science fiction? Not at Absci! Sean and Joshua join us to discuss their AI-driven pipeline for drug discovery. We discuss the tech along with how it might change how we think about healthcare at the most fundamental level.

Nick rewrote our JS Danger game board app from Dojo to React for his talk at React Global Online Summit about componentizing application state with React and XState. On this episode Jerod, KBall, and Feross chat with Nick about the entire process and what he learned along the way. Oh, we also play an epic round of Pro Tip Time!

Matan Peled from Technion University joins Natalie & Mat to discuss his PhD research on meta programming and static analyzers. How does Go’s measure up? What would Matan’s look like if he built one? All that and more!

This is our 5th Kaizen where we talk about the next improvement to changelog.com: we are now running on Fly.io and our PostgreSQL is managed. This is a migration that many were curious about, including Simmy de Klerk, the person that requested this episode. After migrating all our media files to AWS S3 (check episode 40), we thought that this part was going to be easy. Plan met reality. Pull request 407 has all the details. We want to emphasise the type of partner relationships that we seek at Changelog & why they are important to us, as well as to our listeners. Honeycomb & Fly embody the principles that we care about, and Gerhard thinks that we are currently missing a Kubernetes partner.

Today we’re talking with Zach Lloyd, founder of Warp — the terminal being re-imagined for the 21st century and beyond. Warp is a blazingly fast, rust-based terminal that’s being designed from the ground up to work like a modern app. We get into all the details — why now is the right time to re-invent the terminal, where they got started, the business they aim to build around Warp, what it’s going to take to gain adoption and grow, but more importantly — what’s Warp like today to get developers excited and give it a try.

We all hear a lot about MLOps these days, but where does MLOps end and DevOps begin? Our friend Luis from OctoML joins us in this episode to discuss treating AI/ML models as regular software components (once they are trained and ready for deployment). We get into topics including optimization on various kinds of hardware and deployment of models at the edge.

Frank Krueger joined us to talk about solving hard problems. Earlier this year he wrote a blog post titled “Practical Guide to Solving Hard Problems,” and a lot of what he had to say really resonated with us. The premise is simple — if you have to write some code that you’re just not sure how to write…what do you do? What are the practical steps that you can take when you’re feeling stumped? Today’s show goes deep on that subject…practical ways to solve hard problems and ship your best work. Frank has his own podcast called Merge Conflict — check it out at mergeconflict.fm.

Daniel Rosenwasser and Ryan Cavanaugh from the TypeScript team at Microsoft join Nick and Boneskull to catch us up on the latest happening with the TypeScript project, including what’s exciting in the new 4.7 beta release. Then, we dive deep into the new, TC-39 stage 1 Type Annotations proposal, what it is, and what it means for the future of a not really typed JavaScript!

Björn Rabenstein & Bartlomiej Płotka join Mat & Johnny to discuss observability, monitoring and instrumentation for gophers.

Alex Sims, a Senior Software Engineer at James & James, an eCommerce fulfilment company, reached out to us about the Kaizen story of the third-party logistics (3PL) platform that he has been involved with for several years now. The system delivered 16 millions of orders in 10 years, and 4.5 million in the last year alone. All the numbers are going up, and there is only so much that a single PHP monolith deployed as VM images can handle. So how do you even start thinking about the architectural improvements, and inspire everyone involved to move towards better? We encourage you to look at the architectural diagrams in the show notes, especially the 10 year roadmap, and ask Alex for a blog post follow-up. While today’s episode was a good conversation starter, there is a lot that we did not have time to cover.

In the fourth “AI in Africa” spotlight episode, we welcome Leonida Mutuku and Godliver Owomugisha, two experts in applying advanced technology in agriculture. We had a great discussion about ending poverty, hunger, and inequality in Africa via AI innovation. The discussion touches on open data, relevant models, ethics, and more.

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!

Rasmus Porsager created Postgres.js –the fastest full-featured PostgreSQL client for Node.js and Deno. Today he joins Jerod for a deep-dive on Postgres, why he created this open source library, and how you can use it to build pg-backed JavaScript applications.

We often have code that’s similar between projects and we find ourselves copying that code around. In this episode we discuss what to do with this common code, how to organize it, and what code qualifies as this common code.

JS Party is a weekly celebration of JavaScript and the web so fun is at the heart of every episode. We play games like Frontend Feud… (clip from episode #192) Discuss and analyze the news… (clip from episode #213) Explain technical concepts to each other like we’re 5… (clip from episode #195) Debate hot topics like should websites work without JS? (clip from episode #87) Interiew amazing devs like Rich Harris and Una Kravets… (clip from episode #167) This is JS Party! Listen and subscribe today. We’d love to have you with us.

In this episode we talk about launching Dagger with all four founders: Andrea, Eric, Sam & Solomon. While you may remember Sam & Solomon from episode 23, this time we assembled all four superheroes in this story and went deeper, covering nearly three years of refinements, the launch, as well as the world-class team & community that is coming together to solve the next problem of shipping software. Container images and Kubernetes are great steps in the right direction, but now it’s time for the next leap into the future. You can use Dagger to run your CI/CD pipelines locally, without needing to commit and push. You can also use Dagger as a Makefile alternative, which resonates with Gerhard, but go further and your perspective on documentation & automation may start shifting. Gerhard believes that this is the Docker moment of CI/CD.

This week we’re joined by Deepthi Sigireddi, Vitess Maintainer and engineer at PlanetScale — of course we’re talking about all things Vitess. We talk about its origin inside YouTube, how Vitess handles sharding, Deepthi’s journey to Vitess maintainer, when you should begin using it, and how it fits into cloud native infra.

This episode was requested by Tyler Smith who feels that he may not need Kubernetes just yet. Tyler has a few questions about Docker & Docker Swarm, so Andrea Luzzardi, former Docker Swarm Lead, joins us today to answer them. We talk about Docker Swarm beginnings, some of the challenges that it faced, and what Andrea’s recommendation is for Tyler’s journey with Docker Swarm. After dedicating four years of his professional career to Docker Swarm, Andrea is the best person that Gerhard knows to talk about this subject. And guess what, the same thing happened now as it did at KubeCon 2015: Sam pointed to Andrea. It will all make sense in the first five minutes. This one is going to be fun!
