    bit overdue, I made a COG of GEBCO 2025 to save battling their netcdf or zip &amp;quot;geotiff&amp;quot; use /vsicurl prepend, or &amp;#39;s3://idea-gebco-tif/GEBCO_2025.tif&amp;#39; or whatever you prefer https://gist.github.com/mdsumner/c9cfcd49715b2e2925b41222d3d16d2e -&amp;gt; details in this gist to avoid url slop I&amp;#39;ve asked them in the past to create a COG but no dice, we&amp;#39;ve been hosting our own copy since 2019

    why is it only today I now understand that 1) bash functions can be *pasted* in to a session 2) they run with &amp;#39;fun arg&amp;#39; and 3) are the same as C/R syntax with {} and ; for lines, or just newlines fun() { local a=&amp;quot;$1&amp;quot;; echo &amp;quot;$a&amp;quot;; } 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...

    RE: https://rstats.me/@mdsumner/116492521082286632 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

    #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.

    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&amp;#39;t you all want that? I finally have it

    The deeper I get into Zarr and virtualization efforts the bigger the problem seems. There are some huge perspective gaps here, xarray and Zarr reinvented a lot of stuff but then success has prevented a deeper understanding of the landscape. It&amp;#39;s like netcdf woke up from the dark ages and half-modernized. 1/

    #RStats if using devtools::install() you can prevent pak clobbering your system libs with Sys.setenv(PKG_SYSREQS = &amp;quot;false&amp;quot;) 👌

    new GDAL in-dev backend for #xarray coupled directly for Multidim *and* Classic raster (and actually works, pretty good improv this week) #python https://github.com/mdsumner/gdx Please try it out with your most | least favourite Zarr! If you have connection issues just ask I know enough to be dangerous and I&amp;#39;m pretty good with #GDAL would love any feedback 🙏
