In our little deep dive series we're now exploring how cross-compilation in the Conda ecosystem works: prefix.dev/blog/cross-c.... Back in the days, @conda-forge.org rolled this out widely to support osx-arm64 early on, and now for linux-aarch64/ppc64le.
Cross compiling in the Conda ecosystem
Cross compiling is a fundamental capability in modern software development, allowing developers to build packages for different architectures without needing access to the target hardware.

Good to see improvements to this lesser-known part of `numpy`! I was a big fan of the `numpy` masked array from the days of `scikit.timeseries`.
Pandas' choice to use NaN's for missing values was a huge step backwards and is a huge design wart to this day.
