I have found YouTube recommendations to be a great source of new videos on all sorts of topics and this week I started to see a selection of videos from the channel Computerphile out of the School of Computer Science in Nottingham, UK. The first I saw had to do with the early days of computer science including teleprinters, 5-bit paper tape codes, Enigma machines, Bletchley Park code breaking and more.
Learning about the technology that preceded our current day is greatly enlightening and can give a deeper understanding of modern technology than you might expect. Along with the technological education comes great stories from history on how technology was discovered and the effect it had on society.
My favorite videos so far have been those with Professor David Brailsford. He gives clear explanations of early technologies and how they functioned and how they affected the technology that followed. Here are a couple videos on early programming and data storage technologies to get you started. You'll find more great videos like these on the channel.
