Advice for Technical Leaders with Alex Robson Aug 25, 2023

Show notes

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."

When NOT to choose SQL Server to store your data Jun 22, 2023

Show notes

I wrote a blog post inspired by Stephen Vakil's excellent suggested interview question, but I inverted it: When should you NOT choose SQL Server to store your data? My thoughts: * When you don't actually need a database * When you're not using structured data * When you want pure analytics, or something other than a workload involving OLTP * When you need to write to multiple nodes for a single database * When your team wants a PAAS solution (lil pedantic on this, the hosted versions are slightly different) * When your team needs a cheap solution What do you think?
