hearing David Graeber explain a Levi-Strauss style structuralist analysis of vampires and James Bond, as mythic figures, makes me skeptical of that kind of analaysis, as a kind of arbitrary framework with no ability to make scientific claims at all

periodically i listen to the Lazarus radio broadcasts from Deus Ex: Human Revolution and its incredible how perfectly they tuned into the conspiracist wavelength, to the point where it actually presages some real world reactionary attitudes towards trans people, China, etc.

its shocking how much better Fusion 360 is than any free software equivalent. like, it's not even close. and it's not because of inherent functionality, it's because of usability issues that just utterly ruin the free software

something I realized recently is that before the use of foam as a cushioning material in electronics -- where you have a foam block or strip that goes around a closure -- we used to use fabric, like felt

apparently the Brownie 2 movie camera from the 1950s had NO timing mechanism, it just relied on the spring providing fairly even force over a full 30 second shot x_x
