  • #38: How Apache Sedona Solved Big Data’s Hardest Problem with Jia Yu
    Jan 29 2026

    Large Language Models can write poetry and debug code, but they still don't understand the fundamental physics of the real world. Ask an AI to find the "nearest restaurant" to a specific coordinate, and it struggles because it lacks Spatial Intelligence.

    In this episode, we sit down with Jia Yu, the co-creator of Apache Sedona and co-founder of Wherobots, to discuss why geospatial data breaks standard big data engines and how he built the solution that now powers over 2 million downloads a month.

    We trace the 10-year journey from a PhD research paper to a top-level Apache project, diving into the deep technical challenges of distributed computing. Jia explains why spatial data requires a completely different architecture than standard text or numbers and how the industry is finally moving toward a "Spatial Lakehouse" to break down data silos.

    In this episode, we explore:

    - The "Multimodality" Trap: Why mixing vector, raster, and LiDAR data crashes traditional systems.

    - How SedonaDB is bringing massive scale to single-node machines (so you don't always need a cluster).

    - The hardest problem in distributed computing - How to split a map across 1,000 servers without breaking the data.

    - The multi-year fight to get native geometry support into Apache Iceberg.

    - Why the next generation of models must evolve from text-based to spatially intelligent.

  • The Hidden History (and Flaws) of the Zip Code
    Jan 23 2026

    In 1963, the US Postal Service introduced "Mr. Zip" to make mail delivery faster. They never intended for those five digits to determine your insurance premiums, your home value, or your health outcomes.

    In this short deep-dive, we explore how an arbitrary logistical tool became a shorthand for community and why that’s dangerous. From the misleading boundaries of Dallas, Texas, to the tragic data failures during the Flint water crisis, we uncover the real story behind the map.


    Listen in to learn why it's time to move beyond the zip code and start looking at the details that actually matter.

  • #37: From Static Maps to Living Systems: How AI Is Changing Global Mapping with Cliff Allison from TomTom
    Jan 21 2026

    Maps have been around for thousands of years, but what they represent and how they work is changing faster than ever.

    In this episode, I’m joined by Cliff Allison, who has spent more than 30 years building enterprise-scale mapping systems for governments and global organizations. Today, he leads government global sales at TomTom, helping bring modern, AI-powered mapping infrastructure to some of the most demanding use cases in the world.

    We talk about how maps have evolved from static snapshots into living systems that update continuously, how open standards and collaboration made global mapping possible at scale, and why machines are now increasingly interacting with maps and with each other.

    We also explore what this shift means for defense, intelligence, humanitarian response, and decision-making, and why mapping is no longer just a visualization layer, but a foundational system for understanding and predicting the world.

    If you work in geospatial, data, AI, or infrastructure, this conversation will change how you think about maps.
