Spring hot and cold with impending drought.
1. Santa Cruz Weather Station
Mast sensors still broken
2. EPICS
no progress
3. Brini Tracker II
Buttons still work after eleven weeks week of runtime. GPS display update seems to be intermittent but is working at this moment.
4. wktcolor
Various C++ distractions. "Well Known Text" format may be well known, and it is well documented, but doesn't seem to always be well or consistently implemented. Seems that neither boost nor CGAL can read the files produced by GEOS. Plus they can produce some entities that GEOS can't read.
Explored flex/bison and ANTLR C++ bindings, which reminds me how poorly generated code interacts with style checkers.
Now, instead of boost, may use GEOS for WKT, OpenMesh for geometry analysis (because it implements a comprehensible "half-edge" data structure) and igraph for graph analysis, which is needed for the coloring algorithm. Or do it in Go, Ruby, or Julia. Not python. Please, not python. Don't make me do it in python.
5. grass/dcw
After I don't know after how many years - maybe decades - I finally imported DCW (Digital Chart of the World) geographic data into GRASS.

Grr.
Covid-19 case data broken again - this time with no obvious replacement.
