#514 – Focus, Dammit


  • We resume our discussion of “specialist” vs “generalist”, as discussed many other times on the show.
  • We started out talking about how Chris recently hired Bilal, who is a great developer focused on Zephyr. We discuss  how that kind of focus can be useful to a young developer.
  • Chris was first exposed to Zephyr on the BeagleConnect, a new IoT product that uses Greybus coming from the BeagleBoard.org foundation soon.
  • Past guest Greg Davill – MJ of home assembly?
  • 10x engineer
  • Book recommendations:
    • Ultralearning
    • Mastery
    • First 20 Hours
  • Anti-Recommendation
    • Range
  • Tom Brady talking about his improvment over time
  • Michael Phelps (long arms, swimmer) vs Hicham El Guerrouj physiology (long legs, distance runner). Chris later realized this was discussed in James Clear’s Atomic Habit book.
  • Nick Yarris on the Joe Rogan podcast
  • Should we have called the episode, “Chris and Dave talk sports”?

  • The $1 micro page is how Chris started working with the EFM8LB1

  • It is on an 8 year cycle. No one wants to get a “Last time buy” notice, espeically when designed into an industrial scenario.
  • Baremetal programming on the TinyAVR 0
  • Chris was surprised Dave hadn’t heard of a “long range radio power transmitter“, but apparently it’s an older article!
  • Bare Conductive (where past guest Stefan Dzisiewski-Smith works) wrote about how they have maintained an office, albeit changed in the era of COVID
  • Dave mentioned Altium used to have “half cube” (low walls) but not like the startups do with a truly open office plan.
  • WeWork has glass boxes
  • Dave is downsizing commercial property
  • “Does this DMM bring me joy?” a la Marie Kondo
  • Both Dave and Chris downsizing
