This week on The Changelog we’re joined by Adam Wiggins, co-founder and former CTO of Heroku, for an exclusive trip down Heroku memory lane. Adam and Jerod are both tremendous fans of Heroku and believe (to this day) they represent the apex in developer experience for delivering code to production.

We talk through the beginnings of Heroku, the v1 most people have forgotten about, the era of web hosting back in 2008-2010, the serendipity of Silicon Vally in those days, pitching to Y Combinator, the makings of git push heroku, the Heroku style and name, the sale of Heroku to Salesforce, potential regrets — and we tee up part 2 coming next week with Adam going beyond Heroku and the story of Muse.

Chris and Daniel take a step back to look at how generative AI fits into the wider landscape of ML/AI and data science. They talk through the differences in how one approaches “traditional” supervised learning and how practitioners are approaching generative AI based solutions (such as those using Midjourney or GPT family models). Finally, they talk through the risk and compliance implications of generative AI, which was in the news this week in the EU.

This week we’re doing some Linux mythbusting and talking retro gaming with Jay LaCroix from Learn Linux TV. This is a preview of what’s to come from our trip to All Things Open next week. By the way, make sure you come and check us out at booth 60. We’ll be recording podcasts, shaking hands, giving out t-shirts and stickers…and speaking of gaming, you can go head-to-head with us on Mario Kart or Rocket League on the Nintendo Switch. We’re giving that Switch away to a lucky winner at the conference, but you have to play to win. If you’re there, make sure you come see us because we want to see you.

This week we’re talking about product development structures as systems with Lucas da Costa. The last time we had Lucas on the show he was living the text-mode only life, and now we’re more than 3 years later, Lucas has doubled down on all things text mode. Today’s conversation with Lucas maps several ideas he’s shared recently on his blog. We talk about deadlines being pointless, trajectory vs roadmap and the downfall of long-term planning, the practices of daily stand-ups and what to do instead, measuring queues not cycle time, and probably the most controversial of them all — actually talking to your customers. Have you heard? It’s this newly disruptive Agile framework that seems to be working well.

This week we’re back talking to Gergely Orosz — this time not quite about the insane tech hiring market, but more so the flip side, the 180, the not so good tech hiring market, the layoff market and what you can expect. There’s a lot of FUD out there, so hopefully this show gives you a lens into what’s really going on, and what to really expect. Maybe more so, how to keep your job or find a new job. We come to this topic with great compassion and great understanding, so please…there is a community here for you. There’s a lot of people in our Slack. Call it your home, it’s free to join and everyone is welcome.

This week we’re talking with Will McGugan about using the terminal to not just build software, but also to deliver software. Will is a few months into his journey of building Textualize, a company he started around his open source projects Textual and Rich. When combined Textual and Rich give you a Python framework to build beautiful full-featured TUIs for the Terminal. We talk with Will about his big idea of the terminal as a platform, how he got here from first principles, what it takes to build Textual apps and whether or not they can replace not so good web admins, building, launching, and distributing Textual apps, why Python was his choiice of language, the big picture and business model behind Textualize, and why he’s building this as open source and in public.

This week we invited our friend Mat Ryer to join us for some good conversation about some Git tooling that’s been on our radar. You may know Mat from Go Time and also Grafana’s Big Tent, which we help to produce. We speculate, we discuss, we laugh, and Mat even breaks into song a few times. It’s good fun.

This week we’re talking fresh, faster, and new web frameworks by way of JS Party. Yes, today’s show is a web framework sampler because a new batch of web frameworks have emerged. There’s always something new happening in the front-end world and JS Party does an amazing job of keeping us up to date. So…what’s fresh, faster, and new?

The first segment of the show focuses on Deno’s Fresh new web framework. Luca Casonato joins Jerod & Feross to talk about Fresh – a next generation web framework, built for speed, reliability, and simplicity.

In segment two, AngularJS creator Miško Hevery joins Jerod and KBall to talk about Qwik. He says Qwik is a fundamental rethinking of how a web application should work. And he’s attempting to convince Jerod & KBall that the implications of that are BIG.

In the last segment, Amal talks with Fred Schott about Astro 1.0. They go deep on how Astro is built to pull content from anywhere and serve it fast with their next-gen island architecture.

Plus there’s an 8 minute bonus for our ++ subscribers (changelog.com/++). Fred Schott explains Astro Islands and how Astro extracts your UI into smaller, isolated components on the page, and the unused JavaScript gets replaced with lightweight HTML — leading to faster loads and time-to-interactive.

This week we’re talking to Rachel Potvin, former VP of Engineering at GitHub about what it takes to scale engineering. Rachel says it’s a game-changer when engineering scales beyond 100 people. So we asked to her to share everything she has learned in her career of leading and scaling engineering.

Large Language Model (LLM) capabilities have reached new heights and are nothing short of mind-blowing! However, with so many advancements happening at once, it can be overwhelming to keep up with all the latest developments. To help us navigate through this complex terrain, we’ve invited Raj - one of the most adept at explaining State-of-the-Art (SOTA) AI in practical terms - to join us on the podcast.

Raj discusses several intriguing topics such as in-context learning, reasoning, LLM options, and related tooling. But that’s not all! We also hear from Raj about the rapidly growing data science and AI community on TikTok.

eBPF is a revolutionary kernel technology that has lit the cloud native world on fire. If you’re going to have one person explain the excitement, that person would be Liz Rice. Liz is the COSO at Isovalent, creators of the open source Cilium project and pioneers of eBPF tech.

On this episode Liz tells Jerod all about the power of eBPF, where it came from, what kind of new applications its enabling, and who is building the next generation of networking, security, and observability tools with it.

Our 5th annual year-end wrap-up episode! Sit back, relax, pour a glass of your favorite beverage and join us for listener voice mails, our favorite episodes, some must-listens, and of course the top 5 most listened to episodes of the year. Thanks for listening! 💚

What is the model lifecycle like for experimenting with and then deploying generative AI models? Although there are some similarities, this lifecycle differs somewhat from previous data science practices in that models are typically not trained from scratch (or even fine-tuned). Chris and Daniel give a high level overview in this effort and discuss model optimization and serving.

This week we’re talking about serverless Postgres! We’re joined by Nikita Shamgunov, co-founder and CEO of Neon. With Neon, truly serverless PostgreSQL is finally here. Neon isn’t Postgres compatible…it actually is Postgres! Neon is also open source under the Apache License 2.0.

We talk about what a cloud native serverless Postgres looks like, why developers want Postgres and why of the top 5 databases only Postgres is growing (according to DB-Engines Ranking), we talk about how they separated storage and compute to offer autoscaling, branching, and bottomless storage, we also talk about their focus on DX — where they’re getting it right and where they need to improve. Neon is invite only as of the recording and release of this episode, but near the end of the show Nikita shares a few ways to get an invite and early access.

This week we’re joined again by Ben Ubois and we’re talking about RSS. Yes, RSS…the tech that never seems to die and yet so many of us rely on it daily. Ben is the creator of Feedbin, which is self-described as “a nice place to read on the web.” Ben is also the maker of a new app on iOS for people who like podcasts. It’s called Airshow and you can download it at airshow.fm. Ben catches us up on the state of Feedbin, we discuss the nine lives of RSS and its foundational utility for the indie web, the possibilities and short-comings of RSS, we get deep in the weeds on the Podcast 2.0 spec and the work being done on <podcast:chapters>, and Ben also shares the details on his new app called Airshow.

Adam and Jerod are joined once again by James Long. He was on the podcast five years ago discussing the surprise success of Prettier, an opinionated code formatter that’s still in use to this day. This time around we’re going deep on Actual, his personal finance system James built as a business for over 4 years before recently opening it up and making it 100% free.

Has James given up on the business? Or will this move Actual(ly) breathe new life into a piece of software that’s used and beloved by many? Tune in to find out.

Recently a16z released a diagram showing the “Emerging Architectures for LLM Applications.” In this episode, we expand on things covered in that diagram to a more general mental model for the new AI app stack. We cover a variety of things from model “middleware” for caching and control to app orchestration.

Lucas F. Costa on why your daily stand-ups don’t work and host to fix them, Mahdi Yusuf deeply explains Redis, the Deno team announces some big changes coming, DevDash is a highly configurable terminal dashboard for developers and creators & Brett Cannon determines what is a Minimum Viable Python (MVPy).

This week we’re talking with Daniel Thompson about Tauri and their journey to their recent 1.0 release. Tauri is often compared to Electron - it’s a toolkit that lets you build software for all major desktop operating systems using web technologies. It was built for the security-focused, privacy-respecting, and environmentally-conscious software engineering community. The core libraries are written in Rust and the UI layer can be written using virtually any frontend framework. We get into all the details, why Rust, how the project was formed, their resistance (thus far) to venture capital, their full commitment to the freedom virtues of open source, and all the technical bits you need to know to consider it for your next multi-platform project.

Ok Homelabbers, it’s time to unite! Join Adam and his new friend Techno Tim for 1.5 hours of homelab goodness. From networking and WiFi, virtualizing Ubuntu running Docker containers, to Home Assistant and automation, building a Kubernetes cluster, to gutting a perfectly good machine just to build exactly what you need to run the ultimate Plex server — that’s what homelab is about. Let’s do this.

This week we’re talking about LLMs with Simon Willison. We can not avoid this topic. Last time it was Stable Diffusion breaking the internet. This time it’s LLMs breaking the internet. Large Language Models, ChatGPT, Bard, Claude, Bing, GitHub Copilot X, Cody…we cover it all.

Robert C. Martin, aka Uncle Bob, joined the show to talk about the practices of Agile. Bob has written a series of books in order to pass down the wisdom he’s gained over his 50 year software career — books like Clean Architecture, Clean Code, The Clean Coder, The Software Craftsman, and finally Clean Agile — which is the focus of today’s discussion. We cover the origins of his “Uncle Bob” nickname, the Agile Manifesto, why Agile is best suited for developing software, how it applies today, communication patterns for teams, co-location vs distributed, and more importantly Bob shares his “why” for writing this book.

Jarred Sumner’s Bun comes out of the oven, Jeremy Brown doesn’t want you prematurely optimizing, Armin Ronacher’s not excited about his “critical” Python package, Daniel Thompson from Tauri thinks you should check out Rustlings, and we draw a straight line between Functional Programming jargon and boujee Gen Z slang.

This week we’re talking about by Postgres with Craig Kerstiens, Chief Product Officer at Crunchy Data, and a well known ambassador for Postgres. Just Postgres. That’s what this week’s show is about.

PostgreSQL aficionado Craig Kerstiens joins Jerod to talk about his (and our) favorite relational database. Craig details why Postgres is unique in the world of open source databases, which features are most exciting, the many things you can make Postgres do, and what the future might hold. Oh, and some awesome psql tips & tricks!

This week we’re talking to Rasmus Andersson about his journey as a software creator. We talk about the work he’s doing right now on Playbit, a computing environment which encourages playful learning, building, and sharing of software. We also talk about his work on the Inter typeface, as well as the reasons why this font family needed to be free and open source.

This week we’re joined by Jason Bosco, co-founder and CEO of Typesense — the open source Algolia alternative and the easier to use ElasticSearch alternative. For years we’ve used Algolia as our search engine, so we come to this conversation with skin in the game and the scars to prove it. Jason shared how he and his co-founder got started on Typesense, why and how they are “all in” on open source, the options and the paths developers can take to add search to their project, how Typesense compares to ElasticSearch and Algolia, he walks us through getting started, the story of Typesense Cloud, and why they have resisted Venture Capital.

Andreas Kling’s new cross-platform browser project, Dan Hollick’s nerdy deep-dive on QR code tech, Stephan Dilly’s Rust-based terminal UI for Git, Miłosz Piechocki’s opinion on junior vs senior engineers & Divam Gupta’s Tensorflow port of Stable Diffusion.

Jerod is joined by Yehonathan Sharvit, author of Data-Oriented Programming, to discuss the virtues of treating data as a first-class citizen in our applications and the four principles that make it possible.

Welcome to 2023 — we’re kicking off the year talking to Justin Searls about the state of web development and why he just might write a “You Might Not Need React” post. He’s been so productive using Turbo and Stimulus (and tailwind) in Rails 7 that we had to talk about the state of Rails development today and a bunch of other fun topics around building for the web in 2023.
