I'm a computer science professor at UC Irvine, in Orange County, California. See [http://www.ics.uci.edu/~eppstein/ my home page], [https://mathstodon.xyz/@11011110 Mastodon account], [https://11011110.github.io/blog/ blog], or even my Wikipedia article for more about me.

Much of my Wikipedia editing is on mathematics articles, but I've also edited articles on computer science, academic biography, the arts, and California geography, among many other topics. I've also contributed many diagrams and photographs to Wikipedia and Wikimedia Commons.

As an employee of a public university I believe that public outreach is part of my job description, and in that sense that my edits here to subjects within my professional expertise are paid edits. However, the topics and content of my editing here are wide-ranging and entirely self-directed. I neither participate in, nor condone, paid edits for specific articles or specific content.

• ... that although the icosian game was advertised as a "highly amusing game for the drawing room", it was too easy to play and not a commercial success? (24.05)
• ... that the discovery of Descartes' theorem in geometry came from a too-difficult mathematics problem posed to a princess? (24.04)
• .. that Latvian-Soviet artist Karlis Johansons exhibited a skeletal tensegrity form of the Schönhardt polyhedron seven years before Erich Schönhardt's 1928 paper on its mathematics? (24.02)
