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.

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.

This week we’re talking about mainframes with Cameron Seay, Adjunct Professor at East Carolina University and a member of the Governing Board of the Open Mainframe Project. If you’ve been curious about mainframes, this show will be a great guide.

Cameron explains exactly what a mainframe is and how it’s different from the cloud. We talk COBOL and the state of education and opportunities around that language. We cover the state-of-the-art in mainframe land, System Z, Linux on mainframes, and more.

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.

This week on The Changelog we’re talking about Stable Diffusion, DALL-E, and the impact of AI generated art. We invited our good friend Simon Willison on the show today because he wrote a very thorough blog post titled, “Stable Diffusion is a really big deal.”

You may know Simon from his extensive contributions to open source software. Simon is a co-creator of the Django Web framework (which we don’t talk about at all on this show), he’s the creator of Datasette, a multi-tool for exploring and publishing data (which we do talk about on this show)…most of all Simon is a very insightful thinker, which he puts on display here on this episode. We talk from all the angles of this topic, the technical, the innovation, the future and possibilities, the ethical and the moral – we get into it all. The question is, will this era be known as the initial push back to the machine?

Adam and Jerod are joined by Ken Kantzer, co-founder of PKC Security. Ken and his team performed upwards of 20 code audits on well-funded startups. Now that it’s 7 or 8 years later, he wrote up 16 surprising observations and things he learned looking back at the experience. We gotta discuss ’em all!

This week we’re joined by Jacob Kaplan-Moss and we’re talking about his extensive writing on work sample tests. These tests are an exercise, a simulation, or a small slice of real day-to-day work that candidates will perform as part of their job. Over the years, as an engineering leader, Jacob has become a practicing expert in effectively hiring engineers — today he shares a wealth of knowledge on the subject.

Welcome to Song Encoder, a special series of The Changelog podcast featuring people who create at the intersection of software and music. This episode features $STDOUT and contains explicit language.

This week we’re joined by Gergely Orosz and we’re talking about the insane tech hiring market we’re in right now. Gergely was on the show a year ago talking about growing as a software engineer and his book The Tech Resume Inside Out. Now he’s laser focused on Substack with actionable advice for engineering managers and engineers, with a focus on big tech and high-growth startups. On today’s show we dig into his recent coverage of “the perfect storm” that’s causing this insane tech hiring market.

This week we’re joined by Adam Jacob, CEO of System Initiative and Co-Founder of Chef, about open source business models and the model he thinks is the right one to choose, his graceful exit from Chef and some of the details behind Chef’s acquisition in 2020 for $220 million…in cash, and how his perspective on open source has or has not changed as a result. Adam also shared as much stealth mode details as he could about System Initiative.

This week, Richard Hipp returns to catch us up on all things SQLite, his single file webserver written in C called Althttpd, and Fossil – the source code manager he wrote and uses to manage SQLite development instead of Git.

This week we’re joined by Lara Hogan – author of Resilient Management and management coach & trainer for the tech industry. Lara led engineering teams at Kickstarter and Etsy before she, and Deepa Subramaniam stepped away from their deep roots in the tech industry to start Wherewithall – a consultancy that helps level up managers and emerging leaders.

The majority of our conversation focuses on the four primary hats leaders and managers end up wearing; mentoring, coaching, sponsoring, and delivering feedback. We also talk about knowing when you’re ready to lead, empathy and compassion, and learning to lead.

This week we’re joined by Ryan Dahl, Node.js creator, and now the creator of Deno - a simple, modern and secure runtime for JavaScript and TypeScript that uses V8 and is built in Rust.

We talk with Ryan about the massive success of Node and how it impacted his life, and how he eventually created Deno and what he’s doing differently this time around. We also talk about The Deno Company and what’s in store for Deno Deploy.

This week we’re talking about the recent falling out between Elastic and AWS around the relicensing of Elasticsearch and Kibana. Like many in the community, we have been watching this very closely.

Here’s the tldr for context. On January 21st, Elastic posted a blog post sharing their concerns with Amazon/AWS misleading and confusing the community, saying “They have been doing things that we think are just NOT OK since 2015 and it has only gotten worse.” This lead them to relicense Elasticsearch and Kibana with a dual license, a proprietary license and the Sever Side Public License (SSPL). AWS responded two days later stating that they are “stepping up for a truly open source Elasticsearch,” and shared their plans to create and maintain forks of Elasticsearch and Kibana based on the latest ALv2-licensed codebases.

There’s a ton of detail and nuance beneath the surface, so we invited a handful of folks on the show to share their perspective. On today’s show you’ll hear from: Adam Jacob (co-founder and board member of Chef), Heather Meeker (open-source lawyer and the author of the SSPL license), Manish Jain (founder and CTO at Dgraph Labs), Paul Dix (co-founder and CTO at InfluxDB), VM (Vicky) Brasseur (open source & free software business strategist), and Markus Stenqvist (everyday web dev from Sweden).

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!

Nadia Eghbal is back and this time she’s talking with us about her new book Working in Public. If you’re an old school listener you might remember the podcast we produced with Nadia and Mikeal Rogers called Request for Commits. If you weren’t listening then, or can’t remember…don’t worry…the back catalog of Request for Commits is still online and subscribe-able via all the podcast ways. That podcast is still getting listens to this very day!

Obviously we go way back with Nadia…and having a chance to now talk with her through all the details of her new book Working in Public, this was a milestone for this show and Jerod and I. We talked through the reasons she wrote the book in the first place, Nadia’s thoughts on the future of the internet and the connection of creators to the platforms they build their followings on, and we also talk about the health of projects and communities and the challenges we face internet-at-large as well as right here in our backyard in the open source community.

We’re talking about all things all-remote with Darren Murph, Head of Remote at GitLab. Darren is tasked with putting intentional thought and action into place to lead the largest all-remote company in the world. Yes, GitLab is 100% all-remote, as in, no offices…and they employee more than 1,200 people across 67 countries. They’ve been iterating and documenting how to work remotely for years. We cover Darren’s personal story on remote work while he served as managing editor at Engadget, his thoughts on how “work” is evolving and ways to reframe and rethink about when you work, this idea of work life harmony, and the backstory and details of the playbook GitLab released free of charge to the world.

Jason Warner (CTO at GitHub) joined the show to talk with us about the backstory of how he helped to lead GitHub to a $7.5 billion acquisition by Microsoft. Specifically how they trusted their gut not just the data, and how they understood the value they were bringing to market. We also talk about Jason’s focus on “horizon 3” for GitHub, and his thoughts on remote work and how they’re leading GitHub engineering today.

In late 2019, Bill Nichols, a senior member of the technical staff at Carnegie Mellon University with the Software Engineering Institute published his study on “the 10x developer myth.” On this show we talk with Bill about all the details of his research. Is the 10x developer a myth? Let’s find out.

Stephanie Morillo (content strategist and previously editor-in-chief of DigitalOcean and GitHub’s company blogs) wrote a book titled The Developer’s Guide to Content Creation — it’s a book for developers who want to consistently and confidently generate new ideas and publish high-quality technical content.

We talked with Stephanie about why developers should be writing and sharing their ideas, crafting a mission statement for your blog and thoughts on personal brand, her 4 step recipe for generating content ideas, as well as promotional and syndication strategies to consider for your developer blog.

David Cramer joined the show to talk about the recent license change of Sentry to the Business Source License from a BSD 3-clause license. We talk about the details that triggered this change, the specifics of the BSL license and its required parameters, the threat to commercial open source products like Sentry, his concerns for the “open core” model, and what the future of open source might look like in light of protections-oriented source-available licenses like the BSL becoming more common.

We’re talking with Brett Cannon for a behind the scenes look at Guido stepping down as Python’s BDFL (Benevolent dictator for life) and the process they had to go through to establish a new governance model, the various proposed PEPs to establish this new direction, the winning PEP, and what the future holds for Python.

Adam and Jerod talk with Dominic Tarr, creator of event-stream, the IO library that made recent news as the latest malicious package in the npm registry. event-stream was turned malware, designed to target a very specific development environment and harvest account details and private keys from Bitcoin accounts.

They talk through Dominic’s backstory as a prolific contributor to open source, his stance on this package, his work in open source, the sequence of events around the hack, how we can and should handle maintainer-ship of open source infrastructure over the full life-cycle of the code’s usefulness, and what some best practices are for moving forward from this kind of attack.

Adam and Jerod talk with Angie Byron, a core contributor and staple of the Drupal community. We haven’t covered Drupal really (sorry about that), but the call with Angie was inspiring! From the background, to the tech, the usage of the software, the communication at all levels of the community — Drupal is doing something SO RIGHT, and we’re happy to celebrate with them as they march on to the “Framelication” beat of their own drum.

We talked with Eugen Rochko, the creator of Mastodon, about where Mastodon came from the problem it aimed to solve. How it’s not exactly Twitter alternative, although that’s its known claim to fame. Why it’s probably not going anywhere. The ins-and-outs of federation, getting started, running an instance, why you would want to — cool stuff you’ve never considered could be built on top of Mastodon. And finally, the story behind naming posted content a “toot”.

Tim Hockin and Aparna Sinha joined the show to talk about the backstory of Kubernetes inside Google, how Tim and others got it funded, the infrastructure of Kubernetes, and how they’ve been able to succeed by focusing on the community.

Nathan Sobo, founding member of the Atom editor team at GitHub, joined the show take us all the way back to the beginning of Atom to learn where it came from, the founding team, the problem it solves, on through to shipping 1.0 and beyond.

Sandi Metz joined the show to talk about her beginnings on a mainframe, her 30+ years of programming experience, the ins and outs of OOP, her book Practical Object-Oriented Design in Ruby (aka POODR), as well as her latest book 99 Bottles of OOP which she co-authored with Katrina Owen. We also covered a few listener submitted questions at the end.

Big show! Matz, creator of the Ruby programming language, joined the show to discuss where he began as a programmer, the origins of Ruby, its history and future, Ruby 3.0, concurrency and parallelism, Streem, Erlang, Elixir, and more.

This episode is part of our remastered greatest hits collection and features Richard Hipp, the creator of SQLite, talking with us about its history, where it came from, why it has succeeded as a database, how its development has been sustainably funded, and the how and why of it being the most widely deployed database engine in the world.
