I finally managed to track down a decent podcast with more or less precise transcription. The topics are mainly biographies and history of technology but there is a fair range. googling ranlevi should bring up the website. If/ when lingq finally gets the semitic languages going in the right direction, it might be worthwhile contacting him and asking if a few of the podcasts could be imported and shared. It’s a welcome break from full-length books which were starting to depress me.
Today I found out that some of these have been translated into English All Episodes - Curious Minds Podcast including thankfully, the one on Stuxnet.
