wget ml-100k.zip is failing using HTTP protocol

In the section titled **Download and Explore the Dataset** , the wget command below is failing.

```
!wget -N http://files.grouplens.org/datasets/movielens/ml-100k.zip
```

The result of executing the cell is:

```

The problem is resolved if I change the protocol to HTTPS for the wget command.

I plan to run through this sample completely. I will create a PR to fix this and any other occurrences as part of my testing, if this is indeed the correct way to fix this. Please let me know.
