Software Engineering Radio - the podcast for professional software developers

Flavia Saldanha, a consulting data engineer and architect specializing in AI readiness, joins to discuss the evolution of data engineering. She highlights the shift from treating data as a service to a product, stressing the importance of ownership and context. Flavia explains modern lakehouse architectures and the integration of vector databases to manage unstructured data for AI. She emphasizes the need for data engineers to embrace product thinking, governance, and NLP skills, positioning AI as an augmenting co-pilot rather than a replacement.

Join veteran software developer Dave Thomas, co-founder of the Pragmatic Bookshelf and author of The Pragmatic Programmer, as he delves into the world of eBook infrastructure. He explores the evolution of formats like EPUB and Mobi, the importance of reflowable layouts, and how technology shapes the authoring process. Dave highlights the significance of human involvement in writing and how AI tools can assist post-creation. With insights on author workflows and the interplay of writing and technology, he shares a vision for the future of publishing.

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.

Mark Williamson, CTO of Undo and an expert in AI-assisted debugging, dives into the transformative role of AI in debugging processes. He highlights AI's ability to analyze data, automate tedious tasks, and enhance debugging strategies. The discussion covers advanced tools like ChatDBG and time-travel debugging, which allow developers to rewind execution for deeper insights. Mark also emphasizes the benefits for developers of all experience levels and warns of potential risks, including hallucinations and security issues, stressing the importance of human oversight.

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.

Kacper Łukawski, a Senior Developer Advocate at Qdrant, speaks with host Gregory M. Kapfhammer about the Qdrant vector database and similarity search engine. After introducing vector databases and the foundational concepts undergirding similarity search, they dive deep into the Rust-based implementation of Qdrant. Along with comparing and contrasting different vector databases, they also explore the best practices for the performance evaluation of systems like Qdrant. Kacper and Gregory also discuss topics such as the steps for using Python to build an AI-powered application that uses Qdrant. Brought to you by IEEE Computer Society and IEEE Software magazine.

Florian Gilcher, co-founder of Ferrous Systems and the Rust Foundation, speaks with host Giovanni Asproni about the application of Rust in mission- and safety-critical systems. The discussion starts with a brief overview of such systems, and an introduction to Rust, emphasizing aspects that make it well-suited for critical environments. Florian and Giovanni then discuss how Rust compares to C and C++ — two widely used languages in this sector. They proceed to outline important factors that companies should consider when assessing whether to move from C or other languages to Rust. The episode also touches on Ferrocene, an open-source Rust toolchain qualified for safety- and mission-critical systems, which was developed and supported by Ferrous Systems. The conversation ends with some reflections on the future of Rust for mission- and safety-critical applications. Brought to you by IEEE Computer Society and IEEE Software magazine.

Amey Desai, the Chief Technology Officer at Nexla, speaks with host Sriram Panyam about the Model Context Protocol (MCP) and its role in enabling agentic AI systems. The conversation begins with the fundamental challenge that led to MCP's creation: the proliferation of "spaghetti code" and custom integrations as developers tried to connect LLMs to various data sources and APIs. Before MCP, engineers were writing extensive scaffolding code using frameworks such as LangChain and Haystack, spending more time on integration challenges than solving actual business problems. Desai illustrates this with concrete examples, such as building GitHub analytics to track engineering team performance. Previously, this required custom code for multiple API calls, error handling, and orchestration. With MCP, these operations can be defined as simple tool calls, allowing the LLM to handle sequencing and error management in a structured, reasonable manner. The episode explores emerging patterns in MCP development, including auction bidding patterns for multi-agent coordination and orchestration strategies. Desai shares detailed examples from Nexla's work, including a PDF processing system that intelligently routes documents to appropriate tools based on content type, and a data labeling system that coordinates multiple specialized agents. The conversation also touches on Google's competing A2A (Agent-to-Agent) protocol, which Desai positions as solving horizontal agent coordination versus MCP's vertical tool integration approach. He expresses skepticism about A2A's reliability in production environments, comparing it to peer-to-peer systems where failure rates compound across distributed components. Desai concludes with practical advice for enterprises and engineers, emphasizing the importance of embracing AI experimentation while focusing on governance and security rather than getting paralyzed by concerns about hallucination. He recommends starting with simple, high-value use cases like automated deployment pipelines and gradually building expertise with MCP-based solutions.

Daniel Stenberg, a Swedish Internet protocol expert and founder of the curl project, dives into the challenges of integrating Rust into curl, specifically discussing the removal of the Hyper backend. He shares insights on why the last stages of the integration proved to be the toughest, the critical importance of user support, and the lessons learned over five years. Stenberg highlights the positive impacts despite the removal, emphasizing cleaner HTTP handling and valuable architectural insights gained from the attempt.

Elizabeth Figura, a Wine Developer at CodeWeavers, speaks with SE Radio host Jeremy Jung about the Wine compatibility layer and the Proton distribution. They discuss a wide range of details including system calls, what people run with Wine, how games are built differently, conformance and regression testing, native performance, emulating a CPU vs emulating system calls, the role of the Proton downstream distribution, improving Wine compatibility by patching the Linux kernel and other related projects, Wine's history and sustainment, the Crossover commercial distribution, porting games without source code, loading executables and linked libraries, the difference between user space and kernel space, poor Windows API documentation and use of private APIs, debugging compatibility issues, and contributing to the project.
