For a few years I've been tinkering with a project surrounding tracking biometrics against video game play. This led me down the path of wanting accurate gaze tracking, with the goal of overlaying a heatmap of eye movement on captured gameplay to augment a stream for example, or help UI designers/researchers create better interfaces.
When setting up this new site, I wanted to have a dead simple s3 deploy that worked seamlessly with metalsmith. This could be achieved with something as simple as rsync, but I came across bucketful and figured it would work elegantly with my existing metalsmith workflow. This is a quick example of how to set up a metalsmith to s3 deploy.
