A bit OT - does anyone know what tool was used to create those slides? They look very light and clean and something I might experiment with for technical presentations.
Pandoc is pretty similar, just as powerful, and supports multiple output formats. That way you can statically host random files without depending on a go binary running 24/7.
Also be careful with present, it by default runs a sandbox to allow execution of code/examples that I wouldn't trust open to the internet... at least without good justification.
