## 2015

`hd-2015-video-files.txt` file contains links to both presenter and presentaion
videos. They are HD and without captions. Lectures will have meaningful
filenames after download. To download:

```
cat hd-2015-video-files.txt | ./get-2015.sh
```

If you want SD/Mobile/HD-Captions videos, you need to put the links from
CS109 Data Science videos page into `hg-2015-video-pages.txt` file and
extract video links again:`

```
cat hd-2015-video-pages.txt | ./extract-2015.py > hd-video-files-2015.txt
```

## 2014

```
./get.sh hq-urls.txt # for high quality versions
