These are slides for various talks I've given at various conferences. For the most part, they're using reveal.js; to see a presentation locally, do something like:
git clone https://github.com/tych0/presentations
cd presentations && make
cd lca2015 # or the one you're interested in
python -m SimpleHTTPServer
# open a browser to localhost:8000
I also mirror these on slides.tycho.ws, so if you just want to see them in action you can simply go there and select the presentation you want.
