8. Zsh: list recently modified files with (m0) glob qualifiers

Practical zsh glob qualifier tricks: *(m0) selects files modified within the last 24 hours, (mh0) the last hour, with units for months/weeks/minutes/seconds, recursive **/* search, the . qualifier for plain files only, and N to avoid errors in scripts.

9. Its not nostaligia

An essay arguing that things really are worse than they used to be — less nutrient-dense food, planned obsolescence, surveillance cars, AI swallowing content — and that the only way forward is radical self-reliance, not nostalgia.
