To the best of my knowledge (and I would love to be proven wrong!), this is the first time an engineering team has gone on the record with their warts-and-all experience with electromagnetic compatibility (EMC) and safety compliance testing. If you have never heard of compliance before or have no idea what any of this could possibly be about, you're guaranteed to learn something about the world of devices around you. And if you have dealt with EMC: you know how wild and unpredictable the process can be -- and I think you'll enjoy hearing some of our own harrowing details. Either way, this is a technically meaty discussion that I think the HN demographic will enjoy!
