These are the slides and my notes for a talk about temporal databases given at pdxpug 23 April 2020. It is built on reveal.js.
You also can get all the slides as a PDF, or read the slides' Markdown with speaker notes.
The video is on my site.
You can run the slides locally by saying:
npm install
npm start
You can get a slideshow-able PDF by going to http://localhost:8000/?print-pdf in Chrome and printing to a PDF. This is what you want to save as slides.pdf.
You can include speaker notes by going to http://localhost:8000/?print-pdf&showNotes=separate-page in Chrome, printing to a PDF, then printing the PDF. It uses a custom hack to get separate-page speaker notes with a white background. This is what you want to print before you give the talk.
