@[email protected]I make things, I fix things, and quite often break things. A Silicon Valley refugee having lived in the Pacific North West, recently returned to my home, #SantaCruz after too long away.
Three decades in the world of computers and most of it developing the Internet (largely as a Web Thing, but not really).

@[email protected]#FLOSS+#GIS+#JavaScript+#WebGL nerd. #OSGeo charter member, #OpenStreetMap old-timer.
In other words: I do maps on websites, maintaining the Leaflet JS library when I can, but working on Gleo (my own JS+WebGL library) otherwise.
Long-time supporter of Free/Libre/Open-Source Software, as well as Open Data and adjacent subjects.
