Single GDAL, single PROJ, single GEOS, R packages and Python packages linking the same libraries, reticulate bridging cleanly between them, modern numpy, modern Python, modern R, current GDAL master available or latest release

Don't you all want that? I finally have it

#RStats Once in a while, run R CMD check --no-examples and R CMD check --no-tests separately, with _R_CHECK_FORCE_SUGGESTS_=false. The default check ordering plus default Suggests-handling masks bugs that surface only in second-phase code or only when Suggests are absent.

GDAL, Python, GEOS, and gcc need to have a meeting about version number progression

GDAL 3.13.0 PROJ 9.8.1 GEOS 3.14.1
R 4.6.0
Py 3.12.3 numpy 2.4.4
gcc --version
gcc (Ubuntu 13.3.0-6ubuntu2~24.04.1) 13.3.0

attention @tim_salabim@fosstodon.org https://github.com/nathaneastwood/poorman/pull/125#issue-4918332331 if you haven't seen (cf mapview Suggests)

just brushed up on arithmetic with fractions ... I think the child is fine, she can do it

been a long time since I worked through written fractions, had to think!

GDAL and xarray, NCI and Pawsey, working together at last: https://github.com/mdsumner/virtualized/issues/12#issuecomment-4427816203

(learned heaps today!)

RE: @mdsumner@rstats.me

finally, a sufficient demonstration: https://gist.github.com/mdsumner/1b38b300f7dc6e0a8cdfa3cd8fbc84ce

aligned PROJ/GEOS/GDAL and equally capable cli and R and Python, in a simple series of docker images

I walk in and they're playing Kool Thing, coincidence?

I DON'T THINK SO

Fool's Gold may be the greatest song of all time

also I haven't heard it in ages

why is it only today I now understand that 1) bash functions can be *pasted* in to a session 2) they run with 'fun arg' and 3) are the same as C/R syntax with {} and ; for lines, or just newlines

fun() { local a="$1"; echo "$a"; }
fun abc
abc

I have a colleague who gave this talk once but I was distracted on some spatial code or whatever and I totally vagued on all of it. Now I need that Evi Nemeth wonderful book, those chapters on python and perl are fantastic ...
