Presentations & Workshops

My first career was as an academic and I'd been a teaching assistant, tutor, and grader prior to becoming a lecturer, then professor. I enjoy sharing what I know, consider being able to explain something an order of magnitude harder than simply being able to do that thing, and it's rare that I don't grow as a result of interacting with an audience. Over the years I've presented on subjects as varied as historical photographic and printing processes, cartography, and digital literacy at the dawn of the public Internet.

Here's a list of presentations and workshops with links to abstracts (), decks (), and videorecordings () when available.

Let’s Talk About Your Geostack
This aggressively ambitious workshop was given at numerous locations around the country in 2014 and 2015. In retrospect, the kindest thing to say is that it was Quixotic to believe that, on a voluntary basis, it would be possible to track changes in open source mapping technology across three different operating systems. It was enthusiastically received and I met many remarkable people over the course of delivering these workshops.

Rrose: A Leaflet Plugin for Edge Cases
