Eugene Meidinger stops by to chat about Power BI Performance Tuning with Kendra. We talk about the various engines and languages used in Power BI and big-picture strategies for getting performance from the start. Eugene then talks about the community of tools and techniques that can be used to dig in and solve performance problems in Power BI. Eugene's new Pluralsight course on Perf tuning Power BI launches on February 5th, 2024. The first 50 sales will be only $20.

Ever wondered what it's like to be a VP or Director of Engineering? Kendra chats with Alex Robson about leadership in technology, what you can get out of coaching or an MBA program (should you be interested), and what makes a high performing team. We'll also chat about recommended content to hone your tech leadership skills. Alex Robson's site and blog: https://robsonconsulting.services Alex's content recommendations for folks who want to think more about technical leadership: "I believe Camille Fournier and Will Larson are wonderful writers with invaluable insights and advice. For product thinking, I recommend folks read The Lean Startup by Eric Ries, Principles of Lean Product Development Flow by Don Reinertsen, Safer Sooner Happier by Jonathan Smart, and Accelerate by Dr. Nicole Forsgren. Be sure to read books on leadership that are outside of engineering. Dan Pink’s Drive and Eliyahu Goldratt’s The Goal are two of my usual recommendations. Last but not least - read books that are about human behavior. Both economists and psychologists ask important questions that may help you unlock better ways to relate to and understand others. I love Daniel Kahneman’s Thinking Fast and Slow, and highly recommend Mistakes Were Made (but not by me) by Carol Tavins and Elliot Aronson."
