The Sourcegraph Podcast

Pydantic is a Python library for typed validation of external data that has experienced exponential growth since 2020. We'll hear the story of what motivated Samuel to create Pydantic, the most common ways people use it, and the success and growth of FastAPI with Pydantic. Also, Pydantic V2 has not been released yet, but we'll learn what motivated Samuel to rewrite it in Rust, besides being faster and some other things happening with it.  And if you're interested, Samuel is always looking for contributors to Pydantic!  Go ahead and download this episode now to hear more!  Highlights[00:00:59] Beyang gives us his understanding of what Pydantic does, and Samuel tells us two things that people appreciate about Pydantic.[00:02:48] Samuel tells the story of what motivated him to create Pydantic, what the state of the world was at the time, and how it started. [00:04:11] When Samuel first created Pydantic, he tells us if he had a particular use case in mind, and we hear the most common way people use Pydantic and other ways it's used. [00:05:46] Beyang is looking at the Pydantic docs and goes over an example of how you use the base model today. Samuel talks about the new Pydantic V2.[00:07:23] We hear about Samuel's interaction with the FastAPI maintainers. Did he know them, and why does he think they selected Pydantic for their core piece of framework? Samuel mentions Django Ninja, which integrates Pydantic and Django, and Beyang mentions there are many highly starred cool projects using Pydantic and Django.[00:11:53] The new version of Pydantic is written almost completely in Rust, so Samuel reveals why he decided to do the rewrite and what motivated him to use Rust.[00:15:09] Beyang and Samuel discuss some of the Rust bindings so you can see what invoking Python from Rust looks like.[00:21:03] The aspect of Pydantic, which is about translating from Python-type annotations into the core schema, Beyang wonders if that's changing from Pydantic V1 to V2, and Samuel explains that it's all rebuilt.[00:24:03] Beyang wonders if anyone is using the not yet released Pydantic V2 yet. Samuel's response: “I hope for nothing serious because it will change a lot!”[00:24:40] A question in the chat came up for Samuel on Twitch: What motivated you to make the default behavior coercion rather than throwing an error? [00:27:52] Will there be any changes to the public API from Pydantic V1 to V2? Samuel tells us there's one thing that's probably going to make people angry and he explains.[00:29:33] Samuel gives an example of the output from serialization. Beyang wants to help Samuel out and tells him how Sourcegraph can potentially help him. [00:34:25] There are some exciting things coming up for Pydantic that Samuel can't announce quite yet, but he is excited about Pydantic V2 being released. Also, we hear they have GitHub sponsors, but another announcement about sponsors is coming soon.[00:35:35] Samuel announces he would love for you to come and contribute to Pydantic.

In this episode, we are honored to have Daniel Stenberg, the founder and lead developer of cURL, as our guest. cURL is a ubiquitous data transfer utility that grew into a robust library used in billions of applications worldwide. Daniel is a Swedish developer who has been involved in open source for decades. He is also the recipient of the Polhem Prize 2017 for his work on cURL. Join us as we talk to Daniel about his journey with cURL, his passion for open source, and everything in between.

Beyang sits down with John Kodumal, CTO and co-founder of LaunchDarkly. LaunchDarkly is a SaaS feature management platform for developers that allows them to iterate and get code into production quickly and safely by separating feature rollout and code deployment. John begins by talking about his first experiences with computers and programing in the 80s, including teaching himself to us a Dvorak keyboard in the first grade, experimenting with BBS in elementary school, and programming his TI-92 in BASIC to make a shell program so that he could use Reverse Polish Notation (RPN) on it in high school. John shares how he pursued his interest in programming languages throughout higher education and then discusses his employment experiences at Coverity and Atlassian. He talks about how the lessons and experiences from his prior jobs ultimately led him to found LaunchDarkly in 2014 with former classmate, Edith Harbaugh. John dives into how did he first got into feature toggles and feature flags, and then talks about the engineering challenges LaunchDarkly has encountered. John concludes by sharing how he has witnessed LaunchDarkly impact the developer experience and the ongoing, transformational benefits of utilizing their feature management platform.Sourcegraph: https://about.sourcegraph.com

Yves Junqeira and John Ewart are co-founders of YourBase, a build and test runner service that accelerates testing and CI by understanding the implicit dependency graph of your builds. YourBase integrates with most major build tools and employs system call analysis and static language analysis to infer the build dependency structure without the need for manual configuration. It then uses this information to parallelize and cache builds, yielding significant performance improvements.Yves and John reflect on their experiences working as SRE inside Google and SWE inside Amazon and how writing code is different inside these organizations, both compared to one another and to the rest of the world. They share lessons learned and advice for potential developer tool founders.Show notes: https://about.sourcegraph.com/podcast/yves-and-john/notesTranscript: https://about.sourcegraph.com/podcast/yves-and-john/transcript

If you write code on the modern web, it's almost certain that your life has been shaped significantly by Luke Hoban's work. Luke has worked on developer tools his entire career. He started out on Visual Studio, C#, and .NET in the early 2000s, later joined the ECMAScript standards body as a representative of Microsoft, and then became one of the co-founders of the TypeScript programming language. Today, he is the CTO of Pulumi, an infrastructure-as-code company that lets you write your deployment config as code in your favorite language.Luke shares stories from the early days of TypeScript and talks about how it evolved from a two-man team to one of the most successful programming languages and open-source projects. We discuss important inflection points and design decisions that played a key role in TypeScript's runaway success. We also dive into the symbiotic relationship that TypeScript had with another early project just getting off the ground at the time: VS Code. Luke also shares his learnings from his stint at AWS, how his role at Pulumi combines his two passions for programming languages and cloud infrastructure, and how Pulumi brings the niceties of the IDE experience to an area that sorely needs it—infrastructure configuration management.Show notes and transcript: https://about.sourcegraph.com/podcast/luke-hoban/

Evan Culver builds developer tools at Segment, a customer data platform that lets product managers and software teams understand their users through data.Evan's career has spanned many years up and down the software stack, from frontend UI development to infrastructure and ops. For the past five years, his focus has been developer tooling and infrastructure, having worked on these during his tenure at Uber during its hypergrowth years and now on the dev tools team at Segment, where his charter is to "empower the engineers of Segment with the tools to automate, optimize, and streamline their workflows." In this episode, he explains to Beyang what exactly that means, discussing Segment's use of technologies from the AWS ecosystem, the popular open-source secret management tool they created, ChatOps, and various Docker- and Kubernetes-based tools that are useful for managing the deployment of many microservices.Show notes and transcript: https://about.sourcegraph.com/podcast/evan-culver

Charity Majors is the founder and CTO of Honeycomb, an observability tool that combines logs, traces, metrics, and all the relevant data about the production state of your application into a single dataset that can be explored in one place. Charity tells Beyang about how Honeycomb derives its definition of observability for software systems from its original definition in control theory, and how observability differs from monitoring and logging. She shares war stories from her time keeping systems online at Facebook and Parse, gives her predictions about how the landscape of observability and monitoring tools will evolve, and discusses how developer tools can make programming more accessible to everyone.

Ryan Djurovich is a DevOps manager at Xero and former manager of the DevTools team at Cloudflare.
