Hope you can keep posting more videos like that. Plan9 is/was an amazing OS. Maybe you could make a video series talking about Rio? Keep up the great work.
Fantastic presentation. I also love the simplicity and style of your slides. They are not showy, but their readability/sizing/font/feel is perfect. How did you make them?
I have a few plan9 basic servers. minimal programming on my side. So I love this. Please don't stop. BTW what is the presentation program? are you doing some sort of script topng /dev/screen redirect or what?
The presentation program is phil9's spit: shithub.us/phil9/spit/HEAD/info.html For the actual video recording it's a bit of smoke and mirrors, this is actually recorded via OBS using a full drawterm session. It's possible to make proper recordings now with the work sigrid has done, but considering drawterm is what I live out of most of the time anyway this ends up being easier for me.
I guess it depends on which portion of the topics covered were unclear to you. A lot of this talk is designed to contrast against conventional UNIX and Linux designs to build upon the familiar to showcase how Plan 9 differentiates itself. There are plenty of materials that go in to depth on the UNIX side of things but not many books that I would recommend that I feel cover Plan 9 design sensibilities. There are a nice collection of papers however that go in to some more narrative of the design, but those typically assume some background information with UNIX as well. I can also provide some further clarification here in the comments myself if you have specific questions.
