I appreciate the Pycon 2018 account / perspective Naomi. Glad to know Andrew was attending in person and is reaping the benefits of joining a subculture / community, not just learning a computer language [ these go together, as most but not all, science fiction writers failed to predict i.e. that computer languages create tribalism in a positive way ]. Tangential remarks: * I just discovered Pyx this morning: http://pyx.sourceforge.net/ * I've made progress using RhinoScript (rs) a Python module compatible with 2.7 that runs inside a CAD system (proprietary, not unlike ESRI Arc* in that regard). * compiling PostGIS version of postgesql on old OSX Yosemite fails in the homebrew recipe, after about 5 hours doing OK.
