We discuss his beautiful new book, The Radiant Sea, and explore the complex engineering and high-sensitivity optics required to capture living deep-sea creatures. Steve walks us through the evolutionary logic of biological light, how vantablack organisms trap photons in the dark, the horizontal sun-compass navigation of jellyfish blooms, and what it’s like to play games underwater with giant Pacific octopuses and jumbo squids. Dr. Steven Haddock is a Senior Scientist at th
Chris Svec returns to the show to discuss the messy, non-linear realities of engineering management and onboarding new college graduates. We explore why companies should bother hiring fresh grads in the first place, how to prevent junior developers from going dark when they get stuck, and why admitting ignorance publicly is an absolute workplace superpower. Along the way, we dive into managing genius firmware engineering hires, battling technical debt and software entropy, and why your development team shouldn't communicate solely through pull request comments. Chris Svec is the Director of Em
Tyler Hoffman returns to the show to discuss diagnostics and observability data in embedded systems. We catch up on his life after startup acquisition, explore the hows and whys of keeping product data separate from operational data, and consider the realities of fleet management at scale. Tyler is the co-founder of Memfault. Memfault was acquired by Nordic Semiconductor about a year ago. While Nordic has nRF Cloud as a smaller scale solution for Nordic devices (~100 devices), Memfault will continue to maintain support for non-Nordic platforms as well. During the discussion, Tyler advocates fo
Chris and Elecia talk about pushing out of their comfort zone, networking advice, adding STARs and action verbs to resumes, using rust, thermo forming plastics, soldering together audio gear, and winning awards. If you are looking for an update to your resume or are interviewing for a new job and you haven’t heard of the STAR method (Situation, Task, Action, Result), it is a good way to formulate what you’ve done in a way that helps people see your impact. The Rutgers College Career Development Center has a STAR description that includes how to take your current, boring “did the task” resume b
Dr. Victoria Serrano spoke with us about STEM outreach, fostering curiosity, and inspiring students with engineering education. Victoria is a professor at the Technological University of Panama (her faculty page: UTP | Dra. Victoria Serrano).

And Nathan’s excellent Embedded for Everyone Github repo. Nathan recommends The Hardware Hacking Handbook by Jasper van Woudenberg and Colin O'Flynn. It is an excellent resou
Chris and Elecia chat about Leapfrog toys, things they like, large company politics, awards, and open source governance. The Toy Story 5 Trailer with LilyPad toy which is suspiciously similar to the LeapFrog LeapPad tablet. Which is different from the original LeapPad which had cartridges and capacitive touch (capacitive touch was used on the globe as well… the latest globe also has a screen). Why does Elecia want an award? Who knows? But right now, she’s getting ready for a listener to nominate the show (Chris and Elecia) for IEEE’s Meritorious Achievement Award in Outreach and Informal Educa
Sonia Grego speaks with us about a topic no one likes to talk about, but could be used to monitor personal dietary health and widespread disease outbreaks. Toilets! Sonia leads Duke University’s Smart Toilet Lab and the spin out Coprata which makes the Microbiome Activity Tracker. As discussed in the show, when developing a project far from where it will be deployed, there are many common issues. The Lessons Learned chapter of Sonia’s recent book gives an excellent introduction to the unexpected environment far from the comfort of desks. The book is (free online!) Engineering Field Testing of
Kenneth Finnegan entertained us with stories about accidentally contributing to the internet’s ability to network. Wondering how the internet works? All those terms about IPv4, IPv6, BGP, OSPF, CDN and other alphabet soup? Check out the YouTube videos by NetworkChuck. Kenneth writes about his adventures on his blog, The Life of Kenneth. Some of the posts related to this show are: Creating an Internet Exchange for Even More Fun and Less Profit Building an Anycast Secondary DNS Service Building the Micro Mirror Free Software CDN We also mention FCIX aka fcix.net or the Fremont Cabal Internet Exc
