I do a live demo in my talks but it&#x27;s mostly CLI stuff. I start a service (on the local machine, so no internet issues), and do a few simple things like curl requests. Yeah, I could have put the same commands and output on slides, but I think there&#x27;s something about doing the actions in front of people that makes the process seem even more accessible. Like &quot;hey I could do what that guy literally just did&quot;.<p>In fact I did this in a talk I gave just last night. If any of the audience are also HN readers, hope I didn&#x27;t bore you. ;)
