Over the whole weekend is gone TuxCon 2017. According to most people I did decently well with my lecture. I personally am not quite satisfied, certainly there are many things on which to work, because I plan to not be my last such appearance in the future. To be honest most of the presentation almost not remember it, It was like in a trance. I remember the sparse moments in which I look at the clock and realize, that's a decent amount of elapsed time.
It definitely wasn't easy, even taking into account the, the audience was extremely closely targeted and there was a big barrier with the audience.
