The slides of the presentation are here (in PDF form).

If you wwant to remix anything in the slides (and if you know L^AT_EX) what follows are all the files and some directions.

Here are the files:

1. The actual one needs to make this with L^AT_EX source: AaD.tex.
2. Required image files:
   1. CC-BY-SA.pdf
   2. poritz_net_jonathan_qr-code_colorful.pdf

On my machine, which is running Linux Mint "19.2 (Tina)" and which has a quite complete suite of texlive packages (including, crucially, texlive-base and texlive-latex-base; other required L^AT_EX packages will be obvious to anyone who knows L^AT_EX when looking at the \includepackage commands in the AaD.tex source file), at the command line, I do the following in a directory containing the above files:

          pdflatex AaD
          pdflatex AaD
      

If you want just to download one archive with all of those files in it, you could use either of the following two choices:

• AaDFiles.tar — a tar archive, for Linux users
• AaDFiles.zip — a zip archive, for users of other operating systems
