Anurag Goel, Founder/CEO of Render, joins Adam to discuss what they're doing to solve cloud problems for application developers. They just raised $80M they don't even need and they're poised to solve boring problems like object storage, and less boring things like building for the AI era.

Fire up a REPL, grab your favorite Stephen King novel, and hold on to the seat of your pants! Jimmy Miller returns to reveal why, at least for some of us, discovery coding is where it's at.

It seems like everyone is uses the term "agent" differently these days. In this episode, Chris and Daniel dig into the details of tool calling and its connection to agents. They help clarify how LLMs can "talk to" and "interact with" other systems like databases, APIs, web apps, etc. Along the way they share related learning resources.

Jerod is joined by KBall, Nick & Amy to throw one last JS Party! We review last year's predictions, discuss the state of the web dev world, opine on coding AIs (of course) & divulge what comes next for the JS Party crew. Thank you for partying with us all these years! 💚

There is crazy hype and a lot of confusion related to DeepSeek's latest model DeepSeek R1. The products provided by DeepSeek (their version of a ChatGPT-like app) has exploded in popularity. However, ties to China have raised privacy and geopolitical concerns. In this episode, Chris and Daniel cut through the hype to talk about the model, privacy implications, running DeepSeek models securely, and what this signals for open models in 2025.

Glauber Costa, co-founder and CEO of Turso, joins us to discuss libSQL, Limbo, and how they're rewriting SQLite in Rust. We discuss their efforts with libSQL, the challenge of SQLite being in the public domain but not being open for contribution, their choice to rewrite everything with Limbo, how this all plays into the future of the Turso platform, how they test Limbo with Deterministic Simulation Testing (DST), and their plan to replace SQLite.

We seem to be experiencing a surge of video generation tools, models, and applications. However, video generation models generally struggle with some basic physics, like realistic walking motion. This leaves some generated videos lacking true motion with disappointing, simplistic panning camera views. Genmo is focused on the motion side of video generation and has released some of the best open models. Paras joins us to discuss video generation and their journey at Genmo.

Ashley Jeffs shares his journey with Benthos, an open source stream processor that was acquired by Redpanda. We talk about the evolution of data streaming technologies, the challenges he faced while growing the project, the decision to bootstrap versus seek venture capital, and what ultimately led to the acquisition.

Mat gathers the entire cast (sans Natalie, sadly) alongside our producer, Jerod Santo, for one last Go Time. That's right, this is Go Time's finale episode. After eight years and 340 episodes, we are going out on top. Join us one last time, you won't regret it! We share our feelings, reminisce on the good times, list some of our favorite moments & share a few opinions, which may (or may not) be unpopular. 😉

They talk about how Shopify uses generative AI and LLMs to enhance their products, and they take a deeper dive into Sidekick, a first-of-its-kind, AI-enabled commerce assistant that understands a merchant’s business (products, orders, customers) and has been trained to know all about Shopify.

With so many great programming languages having emerged in the last decade, many of them purpose-built, when and where does Go still make sense and how do you make the case for it at work?

Back at React Summit in New York, KBall & Nick sat down with Tom Occhino & Shruti Kapoor for more fascinating conversations. Tom Occhino, a key figure in React's history at Facebook (now Meta), reveals the origin story of React, which began when an ads engineer presented a revolutionary approach to web UI rendering. The discussion extends to React's evolution through Next.js. Then, Shruti Kapoor breaks down React 19's major features, including React Server Components (RSC), the new compiler implementation, and enhanced APIs that promise to streamline development workflows.

Jerod is joined by Hack Clubber Acon, who is fresh off the GitHub Universe stage and ready to tell us all about High Seas, a new initiative by Zach Latta and the Hack Club crew that's incentivizing teens to build cool personal projects by giving away free stuff.

Kyutai, an open science research lab, made headlines over the summer when they released their real-time speech-to-speech AI assistant (beating OpenAI to market with their teased GPT-driven speech-to-speech functionality). Alex from Kyutai joins us in this episode to discuss the research lab, their recent Moshi models, and what might be coming next from the lab. Along the way we discuss small models and the AI ecosystem in France.

Alex Russell answers the question, "If not React, then what?" Csaba Okrona identifies four core problems that create and reinforce knowledge silos, Rob Koch's Markwhen is like Markdown for timelines, Jeff Geerling is quite impressed by Apple's latest iteration on the Mac mini & Sylvain Kerkour took the time to draw a comparison of Amazon's O.G. S3 service with Cloudflare's R2 competitor.

Chris and Daniel dive into what Trump’s impending second term could mean for AI companies, model developers, and regulators, unpacking the potential shifts in policy and innovation. Next, they discuss the latest models, like Qwen, that blur the performance gap between open and closed systems. Finally, they explore new AI tools for meeting clones and AI-driven commerce, sparking a conversation about the balance between digital convenience and fostering genuine human connections.

At React Summit in New York, KBall & Nick sat down with Kent C. Dodds & Theo Browne for two fascinating conversations. Both of them showed us the whole gamut of their personalities! Kent shared his insights on effective teaching methodologies and the future of developer education, while diving deep into React and the Remix/React Router ecosystem, and closing on an appeal for kindness int he world. Then Theo took us behind the scenes of his developer-focused content creation, from streaming to the origins of the T3 stack, and how his online persona (including T3!) is "just him".
