I suppose this is what should have been submitted, because the slides are pretty dense...
I hate video, and don't mind slides. I prefer the submitted form.
The sound quality on that is.. unbearable.
I second this! I also looked at the other video's SDRuby has up, and all of them I have tested are also horrible. If someone from SDRuby is here, FIX YOUR AUDIO!! It sounds like my dad's AM talk radio going through a tunnel!
I would also like a fix. It sounds like someone simply encoded the video with way too strong audio-compression - the original material is probably fine.
I'm very interested in the talk but it's near impossible to understand him and the warbling noise gives me instant-headache. No way for me to consume it as it is.
It seems it has been fixed, I watched it last week and recheck it today, far easier to understand.
