When I was a lad in high school I worked for Walmart. I learned quite a bit about retail at my early age but one of the fascinating things I used in the late 1990s was a wireless inventory unit, colloquially known as a Telxon.

As I waited for them to return with the item I thought about how 25 years of progress had changed that hardware solution into something software focused.
Hardware Genesis
All problems start as hardware problems. If there’s a solution to an issue you’re going to build something first. Need to get somewhere fast? Trains Continue reading
