I start a lot of projects but never finish them. I'd like to pair program w/ someone to get them finished.

The two projects I need help with (a combination of nudging and
programming help) are below. One absolutely requires Mathematica; the
other uses Mathematica but probably doesn't require Mathematica:

This is an attempt to plot where "Diamond Fuji" (the sun setting in a
specific picturesque way over Mount Fuji) will appear. Some URLs for

It is a limited version of my "true horizon" project at https://github.com/barrycarter/bcapps/blob/master/DEM/

The other project is:
https://github.com/barrycarter/bcapps/blob/master/ROSETTA which is an
attempt to convert Mathematica formulas into other languages. In this
case, I need help finding good test formulas, and figuring out how
different languages code the same function. I also need to add
extensive unit testing and verify the answers against Mathematica.

If neither of these seem appealing, feel free to look at
https://github.com/barrycarter/bcapps/blob/master/README-projects.txt
for other things I'm working on, but I'm not sure I need help on all
of those. If you see something you like, let me know and we can figure
out if you can help.
