• SE Radio 696: Flavia Saldanha on Data Engineering for AI

  Flavia Saldanha, a consulting data engineer, joins host Kanchan Shringi to discuss the evolution of data engineering from ETL (extract, transform, load) and data lakes to modern lakehouse architectures enriched with vector databases and embeddings. Flavia explains the industry's shift from treating data as a service to treating it as a product, emphasizing ownership, trust, and business context as critical for AI-readiness. She describes how unified pipelines now serve both business intelligence and AI use cases, combining structured and unstructured data while ensuring semantic enrichment and a single source of truth. She outlines key components of a modern data stack, including data marketplaces, observability tools, data quality checks, orchestration, and embedded governance with lineage tracking. This episode highlights strategies for abstracting tooling, future-proofing architectures, enforcing data privacy, and controlling AI-serving layers to prevent hallucinations. Saldanha concludes that data engineers must move beyond pure ETL thinking, embrace product and NLP skills, and work closely with MLOps, using AI as a co-pilot rather than a replacement.

• SE Radio 695: Dave Thomas on Building eBooks Infrastructure

  Dave Thomas, author of The Pragmatic Programmer, The Manifesto for Agile Software Development, Programming Ruby, Agile Web Development with Rails, Programming Elixir, Simplicity, and co-founder of the Pragmatic Bookshelf, speaks with SE Radio host Gavin Henry about building infrastructure for eBooks. They discuss what an eBook is, the various formats, what infrastructure is needed to build them, how an author writes an book, the history of the Pragmatic Bookshelf, how they have evolved, how to handle links within eBooks, why humans are so important in the writing process, and why AI can help with your writing -- once you've written your content. Thomas discusses PDFs, eBooks, Mobi files, ePub files, CI/CD pipelines, WYSWYG, Markdown files, Pragmatic Markup Language, embedding code, AI agents, images, printing PDFs, JVMs, Java, jRuby, and how Markdown won the plain text writing format wars.

• SE Radio 694: Jennings Anderson and Amy Rose on Overture Maps

  Jennings Anderson, a Software Engineer with Meta Platforms, and Amy Rose, the Chief Technology Officer at Overture Maps Foundation, speak with host Gregory M. Kapfhammer about the Overture Maps project, which creates reliable, easy-to-use, and interoperable open map data. After exploring the foundations of geospatial information systems, Gregory and his guests dive deep into the implementation of Overture Maps through features like the Global Entity Reference System (GERS). In addition to discussing the organizational structure of the Overture Maps Foundation and the need for a unified database of geospatial data, Jennings and Amy explain how to implement applications using data from Overture Maps.

• SE Radio 693: Mark Williamson on AI-Assisted Debugging

  Mark Williamson, CTO of Undo, joins host Priyanka Raghavan to discuss AI-assisted debugging. The conversation is structured around three main objectives: understanding how AI can serve as a debugging assistant;  examining AI-powered debugging tools; exploring whether AI debuggers can independently find and fix bugs. Mark highlights how AI can support debugging with its ability to analyze vast amounts of data, narrow down issues, and even generate tests. From there, the discussion turns to AI debugging tools, with a particular look at ChatDBG's strengths and limitations, with a peek at time travel debugging. In the final segment, they consider several real-world scenarios and evaluate the feasibility and practicality of AI acting autonomously in debugging.

• SE Radio 692: Sourabh Satish on Prompt Injection

  Sourabh Satish, CTO and co-founder of Pangea, speaks with SE Radio's Brijesh Ammanath about prompt injection. Sourabh begins with the basic concepts underlying prompt injection and the key risks it introduces. From there, they take a deep dive into the OWASP Top 10 security concerns for LLMs, and Sourabh explains why prompt injection is the top risk in this list. He describes the $10K Prompt Injection challenge that Pangea ran, and explains the key learnings from the challenge. The episode finishes with discussion of specific prompt-injection techniques and the security guardrails used to counter the risk. Brought to you by IEEE Computer Society and IEEE Software magazine.
