I presented my talk based on the blog posts here at Linux.conf.au 2017; thanks to everyone who responded – your feedback is appreciated. Here are some links for anyone who’s interested:
There won’t be much new in there for anyone who has been following along with the blog series, but it’s a little more succinct. Note that there are some “Deleted scenes” in the slides which cover some of the myths in a slightly different form.
On a different note, some kind folks in the Freenode #ntp IRC channel linked to this great talk by Bryan Fink at the Systems We Love conference last December. It was so much nerdier and more interestingly presented than my talk that I have a serious case of professional jealousy. 🙂
