These are my larger projects with their own project home pages. (See Sketchbook for smaller stuff.)
picotool is a suite of tools and Python libraries for manipulating programs for the PICO-8 fantasy game console. Most people use it to minify the Lua code of large projects to fit into PICO-8’s code character limit. I intend it to be a multi-purpose build workflow tool, though recently added features of PICO-8 have made some of the original intent unnecessary.
I wrote Programming Google App Engine, a technical book about the Google App Engine web application hosting product. The first edition was published by O’Reilly Media in 2009, and we did a second edition in 2012. In 2015, we updated it again, this time splitting the book into a Python edition and Java edition.
