Lucy Guo - Episode 89
In this episode, part of a special collaboration between ACM ByteCast and the American Medical Informatics Association (AMIA)’s For Your Informatics podcast, Sabrina Hsueh hosts engineer and entrepreneur Lucy Guo, co-founder of the infrastructure and software company Scale.AI and founder of Passes, a creator monetization and social media platform. Scale.AI, the data-labeling platform that industrialized human-in-the-loop infrastructure for generative AI and robotics, was acquired by Meta in 2025, making Guo the youngest self-made female billionaire at that time. In the past, she also helped develop Snap Maps as a product designer at Snap and founded Backend Capital, a venture capital firm that primarily funded early-stage engineering startups. Lucy describes her evolution from a childhood hacker into a technology entrepreneur. She stresses a persistent “builder-first,” nimble mindset, the power of surrounding yourself with ambitious peers, solving problems you personally face, and the enduring importance of high-quality data evaluation (especially in high-stakes fields like medicine and clinical trials). She talks about the challenge of pivoting from enterprise data infrastructure to consumer tech, the rising role of female founders and investors enabled by micro-funds; how AI tools are democratizing product-building and design; and her investment focus. Lucy also shares advice for college students and other young builders looking to create a positive and lasting impact.

Ricardo Baeza-Yates - Episode 88
In this episode of ACM ByteCast, host Juan Miguel de Joya welcomes 2025 ACM Luiz André Barroso Award recipient Ricardo Baeza-Yates, the Search Chief Scientist at You.com, holding part-time professor appointments at KTH Royal Institute of Technology (Sweden), Universitat Pompeu Fabra (Spain), and Universidad de Chile. The award recognizes his pioneering contributions to algorithms and information retrieval as well as his leadership in fostering a vibrant transnational research community across Latin America. Baeza-Yates is widely regarded as one of the world’s foremost researchers in information retrieval, celebrated especially for pioneering innovative data structures that have shaped the field. His work has produced influential algorithms for string searching and fuzzy matching, including the well-known Shift-Or algorithm. As a practitioner, Baeza-Yates served as VP of Research for Yahoo Labs, secured 14 patents, and co-founded several startups in Chile and Spain, including Theodora AI, devoted to mitigating technological bias. Among his honors, he received the CLEI Distinction for Contributions to Computing in Latin America in 2009, the Spanish “Ángela Ruiz Robles” Award for research excellence and entrepreneurship in applied computing in 2018, the 2024 Chilean National Prize for Applied Sciences and Technology, and the first Merit Award from the Chilean Computing Science Society in 2025. Ricardo is a member of Academia Europaea, and a Fellow of ACM and IEEE. He is the co-author of Modern Information Retrieval, which became the field's most cited textbook. Ricardo shares his unconventional path into computing, from influential teachers to his discovery of the mathematical and logical beauty of algorithms. He discusses his current research, which focuses on evaluating AI by examining failures, harm, and risk rather than simply measuring success, since errors can have profound consequences in fields like medicine and law, where users may not have the expertise to recognize errors. He advocates for combining reliable search with AI to provide AI agents with accurate, trustworthy information. The conversation also explores the limitations and social consequences of increasingly replacing traditional search with AI-generated responses, including the risk of "cognitive offloading." Ricardo also shares his views on how AI is shifting computer science, offers advice for future AI developers, highlighting ACM’s principles for responsible computing, and advocates for more inclusion of Latin American perspectives in computing and AI.

Kelly Shortridge - Episode 87
In this episode of ACM ByteCast, our special guest host Scott Hanselman (of The Hanselminutes Podcast) welcomes ACM Queue Editorial Board member Kelly Shortridge, Chief Product Officer at Fastly, where she previously served as VP of Security Products. Shortridge is the author of Security Chaos Engineering: Sustaining Resilience in Software and Systems (O'Reilly). An accomplished product executive, software innovator, and internationally recognized technical expert on resilience in complex systems, she is known for the application of behavioral economics, resilience, and DevOps principles to cybersecurity, and modernizing security programs. In the Kelly explains that security chaos engineering is really about resilience engineering—building systems that can recover quickly from inevitable failures. She makes an argument that organizations should prioritize adaptability, redundancy, and recovery over prevention, and encourages greater collaboration between security and platform engineering teams. The wide-ranging conversation covers “metrics theater,” the cost-resilience tradeoff, why software has unique advantages for simulation that we're not leveraging, and where LLMs fit (and don't fit) in security workflows.
