Author Susan Lammers joins the show to discuss the 40th anniversary edition of her classic book, Programmers at Work. We discuss what it was like to interview young and pioneering software developers like Toru Iwatani, C. Wayne Ratliff, and Michael Hawley and how the personal computer revolution was built by individuals seeking freedom from corporate mainframes. Susan also shares her experiences as Editor-in-Chief at Microsoft Press, leading Microsoft's early interactive CD-ROM division, founding Headbone Interactive in the 1990s, and why she's bringing retro games like Elroy Goes Bugzerk back to Steam today.

Kevin Santo Cappuccio, founder of Architeuthis Flux, joins the show to discuss creating Jumperless, an open-source breadboard that replaces physical jumper wires with software-controlled analog crossbar switches. We explore the need for 445 RGB LEDs on a breadboard, using MicroPython to create scriptable circuits, some of the lessons that can be implemented with the Jumperless, and how it might be used to create new instruments. Kevin also shares the story behind his upcoming Barnacle Board. DISCUSSION RESOURCES & LINKS Jumperless Project & Hardware Resources: Jumperless Docs and Discord Jumperless Shop (Also available via CrowdSupply but any discounts only apply to Kevin's shop) JumperlessV5 · GitHub: Open-source hardware files, schematics, and firmware Barnacle Board - GitHub: The future of jumperless includes a modular breadboard with custom-stamped clips and removable protoboard tops Other Resources and Mentions: Wokwi Simulator: Online browser-based electronic circuit simulator Falstad Circuit Simulator: Kevin's favorite browser-based analog simulator Hackaday Prize 2023: Jumperless took 2nd place in the 2023 contest. Peter Griffin made an Microsoft Excel plugin interface for Jumperless, we discussed it with him in episode 505: Potato in a Number Field. Kevin also talked with Chris Gammell of The Amp Hour with more information about the electrical response, timing, and the crossbars. Giant squid - Wikipedia

Elecia and Christopher celebrate winning the IEEE Educational Activities Board Meritorious Achievement Award in Outreach and Informal Education! A huge thank you to Mark Omo and the wonderful listeners who submitted nomination letters. Chris and Elecia talk about learning Hungarian to qualify Chris for an EU passport. They also cover Cory Doctorow's new book The Reverse Centaur's Guide to Life After AI, smart ways to hand off codebases, and the most valuable skills they've relied on through their engineering careers. DISCUSSION RESOURCES & LINKS AWARDS & MILESTONES: IEEE Educational Activities Board Meritorious Achievement Award in Outreach and Informal Education "For creating and sustaining Embedded.fm, a long-running technical engineering podcast that bridges academic theory and industry practice, champions underrepresented groups in STEM, addresses professional ethics, and provides informal technical mentorship to a global audience." Huge thanks to Mark Omo for submitting the nomination and to the other nominators for advocating for our work. To the 450+ guests—artists, makers, educators, entrepreneurs, and traditional engineers—who have generously shared their time and deep expertise with us: this award belongs to you too. And to our incredible global listener community: thank you for tuning in, sharing episodes with your colleagues, and keeping the STEM pipeline strong. If Embedded.fm has ever helped you solve a tricky bug, navigate a career transition, or stay inspired in hardware/software design, we'd love for you to celebrate with us by sharing your favorite episode with an early-career engineer or student this week!

Marine biologist Dr. Steven Haddock joins the show to share the alien, glowing, and transparent wonders of the deep ocean. 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 the Monterey Bay Aquarium Research Institute (MBARI) and an adjunct professor at UC Santa Cruz.

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 Embedded Software Engineering at Insulet. If you're looking for an experienced leadership or management thought partner to help scale your development team, Chris Svec offers private coaching and consulting. You can reach him directly at the email given in the show (or hit the contact link and we'll forward your message along).
