 <p>Dan Phiffer is a programmer and artist based in Brooklyn working on projects that use computer networks as a raw material. In the Fall of 2011 Dan created <a href="https://occupyhere.org/" target="_blank">Occupy.here</a> as an alternative darknet web forum for the Occupy Wall Street encampment and its affiliated working groups. That project has informed related efforts in digital pedagogy, through <a href="https://github.com/our/net" target="_blank">Our Net workshops</a> (and a forthcoming zine), and to working within the platform cooperativism model with the <a href="https://smalldata.coop/" target="_blank">Small Data Cooperative</a>. For his day job, Dan helps build open source mapping tools at <a href="https://mapzen.com/" target="_blank">Mapzen</a> and is an Impact Resident at <a href="https://eyebeam.org/" target="_blank">Eyebeam Art + Tech</a>.</p>
