Leslie Lamport is a computer scientist & mathematician who won ACM’s Turing Award in 2013 for his fundamental contributions to the theory and practice of distributed and concurrent systems. He also created LaTeX and TLA+, a high-level language for “writing down the ideas that go into the program before you do any coding.”
This week it’s storytime with Steve Yegge! Steve came out of retirement to join Sourcegraph as Head of Engineering. Their next frontier is Cody, their AI coding assistant that answers code questions and writes code for you by reading your entire codebase and the code graph. But, we really spent a lot of time talking with Steve about his time at Amazon, Google, and Grab. Ok, it’s storytime!
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.
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!
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.
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 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.
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).
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.
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.
Jon Thornton (Engineering Manager at Squarespace) joined the show to talk about tech debt by way of his post to the Squarespace engineering blog titled “3 Kinds of Good Tech Debt”. We talked through the concept of “good tech debt,” how to leverage it, how to manage it, who’s in charge of it, how it’s similar to ways we leverage financial debt, and how Squarespace uses tech debt to drive product development.
Today we have a very special show for you – we’re talking with Quincy Larson the founder of freeCodeCamp as part of a two-part companion podcast series where we each celebrate our 5 and 10 year anniversaries. This year marks 5 years for freeCodeCamp and 10 years for us here at Changelog. So make sure you check out the freeCodeCamp podcast next week when Quincy ships our episode to their feed. But, on today’s episode we catch up with Quincy on all things freeCodeCamp.
We’re joined by Ron Evans at OSCON on the expo hall floor talking about Go and how it’s eating the world of software. Specifically we’re talking about TinyGo and what they’re doing to bring the Go programming language to micro-controllers and modern web browsers. According to Ron Evans, “embedded systems and Go are the most exciting things happening right now.”
We’re talking all things text mode with Lucas da Costa — we logged his post “How I’m still not using GUIs in 2019” a guide focused on making the terminal your IDE. We talked through his Terminal starter pack which includes: neovim, tmux, iterm2, and zsh by way of oh-my-zsh, his rules for learning vim, the awesomeness of CLI’s, and the pros and cons of graphical and plain text editors.
#Hacktoberfest is a once per year event in the month of October celebrating open source. For many it’s an on ramp to open source, PRs galore for maintainers, and t-shirts for those who submit 5 or more pull requests. In the end, however, it’s about the awareness of open source and its significance to the greater good to humanity as we know it.
Adam and Jerod talk with Daniel Zaltsman, Dev Rel Manager at DigitalOcean and key leader of Hacktoberfest to cover the backstory, where this project began, its impact on open source, how it has had to scale each year by many orders of magnitude, and of course we cover how you can play your part in #Hacktoberfest and give back to open source.
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”.
We’re on location at Microsoft Build 2018 talking with Julia White, Corporate Vice President at Microsoft — a 17 year Microsoft veteran. We talked with Julia about her take on this “new Microsoft”, Satya Nadella’s first appearance as CEO when they revealed the first glimpse of Microsoft’s cloud offering which started with Office, the beginnings of Microsoft Azure, Azure as the world’s computer, and how every company is becoming a software company.
Adam is on location at ZEIT Day talking with Jessica Rose about burnout, Henry Zhu about his passions and pursuit of open source, and Simon Willison about data and his passion for interesting datasets in the world.
Julia Grace joined the show to talk bout about scaling all the things at Slack. Julia is currently the Senior Director of Infrastructure Engineering at Slack, and has been their since 2015 — so she’s seen Slack during its hyper-growth. We talked about Slack’s growth and scale challenges, scaling engineering teams, the responsibilities and challenges of being a manager, communicating up and communicating down, quality of service and reliability, and what it takes to build high performing leadership teams.
If you find yourself chasing shiny objects and squirrels all time, you should 💯 listen to this episode featuring Ozan Onay (President of Bradfield School of Computer Science) where we discuss his recent blog post entitled You Are Not Google which was the #1 link in Changelog Weekly - Issue #159. This show is full of wisdom and advice for every developer out there.
Johannes Schickling (Founder of Graphcool) joined the show to talk about GraphQL — an application layer query language from Facebook. We talked about what it is, where it makes sense to use it, its role in serverless architectures, getting docs for free via Schemas and Types, and the community that’s rallying around this new way to think about APIs.
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.
Daniel Stenberg joined the show to talk about curl and libcurl and how he has spent at least 2 hours every day for the past 17 years working on and maintaining curl. That’s over 13k hours! We covered the origins of curl, how he chooses projects to work on, why he has remained so dedicated to curl all these years, the various version control systems curl has used, licensing, and more.
