The post linked above has a .pptx file extension.
That is a Microsoft Power Point presentation extension. If you don't have Power Point installed on your computer you won't see anything - and, in fact, get an error message.
This page:

has a whole bunch of BAL tech stuff.
Some articles you can watch or download but a few are Power Point only.
