Smarter Everyday has a couple longer series that are superb: - An interview with a NASA programmer that worked on the Apollo computers (with Linus from LTT) - An embed on a nuclear sub - Several videos with the US Coast Guard - A VERY technical tour of a Kodak film factory. Don’t sleep on some of the longer extended videos on the secondary channel either, the film chemistry one from just this week is fascinating.
