Arthur Whitney writes compact code in C (and in k of course); most things fit on one A4 which is actually very nice to me as an older person. I cannot remember as much as I could (although i'm still ok) and just seeing everything I need to know for a full program on 1 page is very nice vs searching through a billion files, jump to them, read, jump back and actually mostly forgotten the 1000 steps between (I know, this refers to a typical overarchitected codebase I have to work on, but I see many of those unfortunately).
