ACM ByteCast

In this episode of ACM ByteCast, Rashmi Mohan hosts ACM Fellow Margo Seltzer, co-recipient of the 2020 ACM Software System Award (shared with Mike Olson of Cloudera and Keith Bostic of MongoDB). She is the Canada 150 Research Chair in Computer Systems and the Cheriton Family Chair in Computer Science at the University of British Columbia. Previously, Seltzer was the Herchel Smith Professor of Computer Science at Harvard University’s John A. Paulson School of Engineering and Applied Sciences and Director at the Center for Research on Computation and Society. She is especially renowned for her work on log-structured file systems, databases, and wide-scale caching. Seltzer was previously CTO of Sleepycat Software, developers of the BerkeleyDB embedded database, later acquired by Oracle Corporation. Among her many honors, she is the recipient of the 2020 SIGMOD Systems Award and was recently named one of the “Top 20 Canadian Women in Cyber Security” by IT World Canada. In the wide-ranging interview, Margo discusses her early years growing up in a high-achieving family and later studying applied mathematics at Harvard (before they had a CS major). She also recalls the amazing time in grad school studying under four legendary professors (including her advisor, Michael Stonebraker), and the origins of BerkeleyDB, which started as a graduate student open-source project and later became Sleepycat Software. Margo emphasizes the importance of taking risks and getting out of your comfort zone (and comfort research area) and inter-disciplinary collaboration, something she encourages in mentoring her students and junior colleagues. She also stresses the responsibility that comes with success and the value of mentoring students and providing guidance for impactful roles in service as well as research.

In this episode, the first of a special collaboration between ACM ByteCast and the American Medical Informatics Association (AMIA)’s For Your Informatics podcast, hosts Karmen Williams and Sabrina Hsueh welcome Wendy Chapman, Associate Dean of Digital Health and Informatics at the University of Melbourne and Director of the Centre for Digital Transformation of Health. Her research focuses on developing computer algorithms to understand information typed into electronic medical records and natural language processing of clinical texts. She is an elected fellow of the American College of Medical Informatics and the US National Academy of Medicine. Wendy discusses her journey from an undergraduate background in linguistics and Chinese literature to completing a PhD in Medical Informatics at the University of Utah and learning to program from scratch. She also describes moving to Australia when saw an opportunity to grow the field of digital health in Melbourne. She identifies the most pressing issues she is faced with in her new role and provides valuable advice based on her most impactful career moves. Wendy also shares with Karmen and Sabrina the development of the Digital Health Validitron at the University of Melbourne, which will guide innovators through questions in order to obtain funding and reimbursement. Finally, she identifies the areas in which ACM and AMIA can partner together in order to create a real impact in the field.

In this episode of ACM ByteCast, Rashmi Mohan hosts David Heinemeier Hansson, cofounder and CTO of Basecamp. In addition to his work on this popular project management application, he is also the creator of the open-source web framework Ruby on Rails, used by some of the best-known technology companies, such as Twitter, Shopify, GitHub, Airbnb, and Square, and more than a million other web applications. He is also a prolific author of multiple bestselling books on building and running a successful business, as well as a Le Mans class-winning racecar driver. David recounts discovering Ruby in the early 2000s and using it to create Basecamp, work which spawned Ruby on Rails. He dives into the process of creating Basecamp, whose aim was to solve the problem of communication with clients, as well as building a self-sustaining community with Ruby on Rails. He also explains his personal approach to open-source software, one of his passions. David also looks back on lessons he learned in business school—including the marketing aspect of technology—and how he applied these lessons to building his own business. He also reveals his experience with remote work and what he’s most excited about for the future.

In this episode of ACM ByteCast, Rashmi Mohan hosts 2017 ACM Grace Murray Hopper Award recipient Amanda Randles, the Alfred Winborne and Victoria Stover Mordecai Assistant Professor of Biomedical Sciences at Duke University’s Department of Biomedical Engineering. She is also Assistant Professor of Computer Science and Biomedical Engineering and a member of the Duke Cancer Institute. She has received the National Science Foundation Career Award and was selected as one of the 10 researchers to work on the Aurora Exascale Supercomputer. Her visionary work in simulating blood flow through the human body in a system called HARVEY, led her to be featured in the MIT Tech Review Innovators Under 35 list. Amanda talks about growing up in Michigan and being inspired early on by her high school computer science teacher. She talks about her passion, which lies in using the largest supercomputers in the world to answer questions otherwise left unanswered, and her Duke research group’s focus on building large scale personalized blood flow simulations. She also discusses her 3-year involvement with IBM’s Blue Gene Team, where she learned how to debug programs and identify and work through problems collaboratively, and her time at Harvard University, where she learned about fluid dynamics and started writing HARVEY from scratch. She also describes the fascinating contributions her team made to address ventilator shortages during the early days of the COVID-19 pandemic.

In this episode of ACM ByteCast, our special guest host Scott Hanselman (of The Hanselminutes Podcast) welcomes Jelani Nelson, Professor of Electrical Engineering and Computer Science and a member of the Theory Group at the University of California, Berkeley and a Research Scientist at Google. His areas of interest include the theory of computation, as well as the design and analysis of algorithms, especially for massive datasets. Jelani is a member of ACM's Special Interest Group on Algorithms and Computation Theory (SIGACT)’s Committee for the Advancement of Theoretical Computer Science (CATCS). Among his honors, he won the 2014 Presidential Early Career Award for Scientists and Engineers. He is the creator of AddisCoder, a computer science summer program for Ethiopian high school students in Addis Ababa. Jelani and Scott discuss his journey from learning HTML when he was 12 to becoming a theoretical computer scientist. They talk about the spectrum between software engineering and theory and how even theoretical CS research can have an impact on industry practice; teaching his introduction to algorithms course of more than 700 students; running a highly successful algorithmic boot camp for students in Ethiopia to learn coding; and the times he feels most accomplished in his work.

Bryan describes discovering computing as a kid growing up in the 80s and falling in love with the challenge of solving difficult problems and getting hard programs to work. He talks about DTrace, which he first conceived as an undergraduate at Brown University and co-designed at Sun Microsystems (later acquired by Oracle). He also explains why he thinks open source will conquer every domain, his current challenge of designing a rack-scale computer for the enterprise, and much more.

In this episode of ACM ByteCast, our special guest host Scott Hanselman (of The Hanselminutes Podcast) welcomes 2013 ACM A.M. Turing Award laureate Leslie Lamport of Microsoft Research, best known for his seminal work in distributed and concurrent systems, and as the initial developer of the document preparation system LaTeX and the author of its first manual. Among his many honors and recognitions, Lamport is a Fellow of ACM and has received the IEEE Emanuel R. Piore Award, the Dijkstra Prize, and the IEEE John von Neumann Medal. Leslie shares his journey into computing, which started out as something he only did in his spare time as a mathematician. Scott and Leslie discuss the differences and similarities between computer science and software engineering, the math involved in Leslie’s high-level temporal logic of actions (TLA), which can help solve the famous Byzantine Generals Problem, and the algorithms Leslie himself has created. He also reflects on how the building of distributed systems has changes since the 60s and 70s. Subscribe to the Hanselminutes Podcast: https://www.hanselminutes.com/.
