Gizmo tinkering, personal engineering projects of all kinds, bug hunt recounts and some scientific stuff. Also lighter fluff of all kinds.

Just yesterday I compiled a gigantic ublock filter for HN that hides political posts, everything related to artificial intelligence, "founder culture" as you call it, tech business stuff, legal matters, everything webdev related, certain topics that young tech bros seem to be obsessed with (psychedelics, self improvement, note taking apps, hanki panki or whatever etc) and posts about scientific topics that tend to attract habitual incorrectorrists.

So far it has worked wonders and made HN pleasant to browse again.
