Cloud services are all the rage right now, but are they worth it? There are many aspects to the question, and the answer is almost always going to be “it depends.” Do you really need to spin up capacity more quickly than you can buy hardware and get it running?

Reading people from the past can sometimes show us where today’s blind spots are–but sometimes we can just find the blind spots of the people who lived then. In this episode of the Hedge, Tom, Eyvonne, and Russ finish going through a selection of quotes from an engineering book published in 1911. This time, we find there are some things to agree wi…
