A very simple example of holding a C++ class in Python.
#include <Python.h>
struct MyClass {
int val;
MyClass(void) : val(42) {}
};
#ifdef __cplusplus
extern "C" {
#endif // __cplusplus

A wrapper around Rcartogram::cartogram for shape files.
# A wrapper around Rcartogram::cartogram for shape files.
#
# @param polys: Either a SpatialPolygonsDataFrame or the path to a shape file.
# @param variable: Either a string giving the name of the variable to used in polys@data, or a vector
# of the same length as polys@polygons.
# @param nx: The number of columns in the raster used to represent the region.
# @param ny: The number of rows in the raster used to represent the region.
# @param buffer.by: The proportion width of the buffer to add to the region (see ?Rcartogram::addBoundary).
#
# @return The new boundaries as A SpatialPolygonsDataFrame with the attribute 'cartogram.scaling.var'.

Using Pi as a (very slow) random number generator.
/*
This program implements the BBP algorithm to generate a few hexadecimal
digits beginning immediately after a given position id, or in other words
beginning at position id + 1. On most systems using IEEE 64-bit floating-
point arithmetic, this code works correctly so long as d is less than
approximately 1.18 x 10^7. If 80-bit arithmetic can be employed, this limit
is significantly higher. Whatever arithmetic is used, results for a given
position id can be checked by repeating with id-1 or id+1, and verifying
that the hex digits perfectly overlap with an offset of one, except possibly
for a few trailing digits. The resulting fractions are typically accurate

Summary of git commands for submodules

This is based on this very informative post.

Configuration settings

  • diff.submodule = log (so you get clearer container diffs when referenced submodule commits changed).
  • fetch.recurseSubmodules = on-demand (so you are confident new referenced commits for known submodules get fetched with container updates).
  • status.submoduleSummary = true (so git status gets useful again when a referenced submodule commit changed).

Adding or cloning

  • Initial add: git submodule add
