C10M: Defending The Internet At Scale. This is a surprisingly deep video about how to program very big machines with huge RAM and lots of CPU cores under Linux disguised as an introduction video to imaginary problem for web developers. You didn’t know how poll or select scale when machine characteristics grow? You can learn about it from the video.

Cloud Haskell. This is a video about how to design a distributed system disguised as a tutorial for a specific library. Really useful to watch even if you don’t practice Haskell. It covers lots of dimensions of a distributed system, such as process execution and distribution, instance allocation and configuration and the way to unify them in a coherent library.
