Friend who is not a software person sent me this tweet, which amused me as it did them. They asked if “runk” was real, which I assume not.
But what are some good examples of real ones like this? xz became famous for the hack of course, so i then read a bit about how important this compression algorithm is/was.
A few libraries come to mind immediately: fftw (I think the most widely used fft library) or GMP (I think the most used multi precision library).
