That's a shame, I thought it was a quite interesting explanation of all those Google deep dream images.
There was another computerphile video just on the neural networks used, linked in the description, but I didn't watch it.
The most basic idea is reasonably straightforward - the neural networks are being used to classify images, so there is a low level categoriser for low level things like edges and corners, and then a higher level one that looks for how edges and corners are arranged to make, say, ears... and then a top level one to look for how ears and noses are arranged to make cats.
The complicated bit is that then they run the device backwards, so instead of using it to assign a probability that something is an ear, they actually put the ear in the image even though it wasn't really there to start with.
Since I'm not really saying anything that they didn't, I'm assuming that didn't help?
I was so overwhelmed by this one. So very lost.

"C" Programming Language: Brian Kernighan - Computerphile
I was actually wondering if anyone else had heard of Brian Kernighan, Dennis Ritchie and Ken Thompson... this video is going to be more interesting to people with a comp sci background (or at least a Unix or linux background).
These are the guys from Bell Labs who used a spare minicomputer to write an operating system and a sort of word processor or computerised publishing system in the 70s, before you could just buy a word processor.
The system had some interesting features, like being more portable than was normal of operating systems before it (the subject of this video) and its habit of treating every file as a text file (previous operating systems tended to treat a text file as different to a database file as different to a video file for instance).
I'm sure there are videos around here somewhere that explain it.... I know computerphile had another interview about the typesetting part:

I haven't watched this video on Unix, but it's very likely *related=http://videosift.com/video/AT-T-Archives-The-UNIX-Operating-System too.
That was so over my head.

Elegant Compression in Text (The LZ 77 Method)
To further illustrate the complexity involved in compression, think about the following:
If I replace "The computerphile channel handles computer topics" with "The computerphile channel handles <30,8> topics", how does the decoder tell the difference between the 2 byte <30,8> pointer and the data it represents?

Tainted Love on Hard Drives - No Clever Title Included
It's likely an Arduino board in the middle running code specifically written for this. I've seen similar projects. Some actually use custom MIDI files (1 "instrument" per drive), others have the songs coded by hand (C, python, etc).
I just posted another video that has a good explanation:

Wondering what he's using as a sequencer there in the middle...Anyone?
