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?

This week we’re sharing the most popular episode of Go Time from last year — Go Time #196. We believe this episode was the most popular because it’s all about building actually maintainable software and what goes into that. Kris Brandow is joined by Johnny Boursiquot, Ian Lopshire, and Sam Boyer. There’s lots of hot takes, disagreements, and unpopular opinions.

This is part two of a three part mini-series led by Kris on maintenance. Make sure you check out Go Time #195 and Go Time #202 to continue the series.

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 talking with Bruce Schneier — cryptographer, computer security professional, privacy specialist, and writer (of many books). He calls himself a “public-interest technologist”, a term he coined himself, and works at the intersection of security, technology, and people.

Bruce has been writing about security issues on his blog since 2004, his monthly newsletter has been going since 1998, he’s a fellow and lecturer at Harvard’s Kennedy School, a board member of the EFF, and the Chief of Security Architecture at Inrupt. Long story short, Bruce has credentials to back up his opinions and on today’s show we dig into the state of cyber-security, security and privacy best practices, his thoughts on Bitcoin (and other crypto-currencies), Tim Berners-Lee’s Solid project, and of course we asked Bruce to share his advice for today’s developers building the software systems of tomorrow.

Today we have a special treat. A conversation with Brian Kernighan! Brian’s been in the software game since the beginning of Unix. Yes, he was there at Bell Labs when it all began. And he is still at it today, writing books and teaching the next generation at Princeton.

This is an epic and wide ranging conversation. You’ll hear about the birth of Unix, Ken Thompson’s unique skillset, why Brian thinks C has stood the test of time, his thoughts on modern languages like Go and Rust, what’s changed in 50 years of software, what makes platforms like Unix and the web so powerful, his take as a professor on the trend of programmers skipping the university track, and so much more.

Seriously, this is a must-listen.

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.

Our 4th annual year-end wrap-up episode! We don’t naval gaze often, but when we do… we make sure you get your money’s worth. Reflections, most popular episodes, our favs, and new this year: listener voice mails. Thanks for listening! 💚

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.

On this special edition of The Changelog, we tell Vim’s story from the mouths of its users. Julia Evans, Drew Neil, Suz Hinton, and Gary Bernhardt join Jerod Santo for a deep and wide-ranging discussion about “the best text editor that anyone ever wrote.”

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!

Maxime Vaillancourt joined us to talk about Shopify’s massive storefront rewrite from a Ruby on Rails monolith to a completely new implementation written in Ruby. It’s a fairly well known opinion that rewrites are “the single worst strategic mistake that any software company can make” and generally something “you should never do.” But Maxime and the team at Shopify have proved successful in their efforts in this massive storefront rewrite and today’s conversation covers all the details.

We’re joined by Simon Eskildsen, Principal Engineer at Shopify, talking about how he uses a concept called napkin math where you use first-principle thinking to estimate systems without writing any code. By the end of the show we were estimating pretty much everything using napkin math.

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.

Dave Kerr joins Jerod to discuss the various laws, theories, principles, and patterns that we developers find useful in our work and life. We unpack Hanlon’s Razor, Gall’s Law, Murphy’s Law, Kernighan’s Law, and too many others to list here.

We’re revisiting Shape Up and product development thoughts with Ryan Singer, Head of Product Strategy at Basecamp. Last August we talked with Ryan when he first launched his book Shape Up and now we’re back to see how Shape Up is shaping up — “How are teams using the wisdom in this book to actually ship work that matters? How does Shape Up work in new versus existing products?” We also talk about the concept of longitudinal thinking and the way it’s impacting Ryan’s designs, plus a grab bag of topics in the last segment.

The incomparable Jessica Kerr drops by with a grab-bag of amazing topics. Understanding software systems, transferring knowledge between devs, building relationships, using VS Code & Docker to code together, observability as a logical extension of TDD, and a whole lot more.

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.

We’re talking with Josh Aas, the Executive Director of the Internet Security Research Group, which is the legal entity behind the Let’s Encrypt certificate authority. In June of 2017, Let’s Encrypt celebrated 100 Million certificates issued. Now, just about 2.5 years later, that number has grown to 1 Billion and 200 Million websites served. We talk with Josh about his journey and what it’s taken to build and grow Let’s Encrypt to enable a secure by default internet for everyone.

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.

Lauren Tan joined us to talk about her blog post titled “Does it spark joy?” In this post Lauren shared the news of her resignation as an engineering manager at Netflix to return to being a software engineer. We examine the career trajectory of a software engineer and the seemingly inevitable draw to management for continued career growth. The idea of understanding “What are you optimizing for?” and whether or not what you’re doing truly brings you joy.

Frank Karlitschek joined us to talk about Nextcloud - a self-hosted free & open source community-driven productivity platform that’s safe home for all your data. We talk about how Nextcloud was forked from ownCloud, successful ways to run community-driven open source projects, open core vs open source, aligned incentives, and the challenges Nextcloud is facing to increase adoption and grow.

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.
