    Claude Code makes several thousand dollars in 30 minutes, with Patrick McKenzie

    Patrick McKenzie (patio11) walks through a coding session with Claude Code to demonstrate what the fuss is about. The business problem: recovering failed subscription payments that required coordinating APIs across Stripe, Ghost, and email providers, and the surprising experience of watching Claude read documentation, resolve dependency conflicts, and make sensible security choices. The episode offers a pedantic level of detail on why the sharpest technologists use words like “fundamentally transformed” to describe the impact of LLMs on coding. – Full annotated transcript available here: www.complexsystemspodcast.com/claude-code/ –Sponsor: Framer Building and maintaining marketing websites shouldn’t slow down your engineers.

    We should stop burning pharma trials’ lab notes, with Ruxandra Teslo

    Patrick McKenzie (patio11) is joined by Ruxandra Teslo to discuss why drug development keeps getting more expensive despite revolutionary new treatment modalities from GLP-1 agonists to gene therapies. They discuss Eroom’s Law (Moore’s Law in reverse) and Ruxandra's Common Technical Document Project, which aims to build the "Stack Overflow of clinical development" by making regulatory submissions publicly accessible. This will fill a present hole in the education of researchers, lower barriers for small biotechs, and accelerate drug discovery.– Full transcript available here: https://www.complexsystemspodcast.com/ruxandra-teslo/ –Sponsor: FramerBuilding and maintaining marketing websites shouldn’t slow down your engineers.

    Your support rep is also trapped in this call, with Des Traynor of Intercom

    Patrick McKenzie (patio11) sits down with Intercom co-founder Des Traynor to examine customer support through the lens of Conway's Law, Goodhart's Law, and several decades of accumulated organizational scar tissue. They discuss how AI agents are democratizing white-glove service, why modern LLMs have retrained user expectations around “chatbots” very quickly, and the surprisingly liberating effect of talking to something that will never judge you for missing a loan payment.– Full transcript available here: www.complexsystemspodcast.com/des-traynor/ –Sponsor: MongoDB Tired of database limitations and architectures that break when you scale?

    The magic spell that makes banks give you your money back

    Patrick McKenzie (@patio11) reads his latest Bits about Money essay explaining why he “loves Regulation E more than any rational person does.” He explains how Reg E created a privately-administered legal system processing over 100 million complaints annually—dwarfing the formal U.S. court system—and why banks are now trying to avoid these obligations for Zelle's nine figure fraud problem.– Full transcript available here: www.complexsystemspodcast.com/the-magic-spell-reg-e/ – Sponsors: MongoDB & FramerTired of database limitations and architectures that break when you scale?

    Understanding perpetual futures

    In this episode, Patrick McKenzie (patio11) walks through how perpetual futures work, from funding rates to liquidations to the surprise of automatic deleveraging. Perps are the dominant trading mechanism in crypto (6-8X larger than spot volume) and exist primarily to let exchanges and market makers run casinos more capital-efficiently. He explains why this intellectually interesting innovation probably won't escape crypto, despite what crypto enthusiasts might expect.– Full transcript available here: www.complexsystemspodcast.com/understanding-perpetual-futures/ – Sponsor: Framer is a design and publishing platform that collapses the toolchain between wireframes and production-ready websites.
