One nitpick is the video kept freezing for me, I'd refresh and it would play another minute or so and then freeze again. Maybe just the HN effect or something.
That depends of course on your cultural and language background. In Germany, "NS" in a standard abbrevation for "Nationalsozialismus", the ideology of the Hitler regime from which the abbreviation "Nazi" derives. For instance, the time between '33 and '45 is typically called "NS-Zeit".
I don't think there's any danger, though, that anyone will confuse this website's content with anything related to that meaning ;-)
Of course "NS" is a play on Apple's Foundation classes that use the NextStep prefix for pseudo-namespaces.
It's unfortunate that it has connotations from our sordid past.
RSS feed? How often are planing to release episodes?
I'll be releasing a video each week.
I still recommend that everyone learn how memory management works before jumping into ARC. Much of what I do still has to support 4.0. That said, ARC is pretty badass, and I plan on doing a screencast on ARC in the near future.
