Lukas Süss’s (#mechadense) motivations for #self-replicating #hardware
"ReChain" is #mechadense’s #reprap design for a proposed class of #mechanical frame systems for #3D-printing, robots and structures that totally abjures the use of frictional fasteners and “naïve use of clips”, instead using only tension to get stiffness.

Dan Luu’s notes on why #productivity and velocity matter. “It is also not my personal experience that coding speed doesn’t matter.”
Dan Luu comments that the 95th percentile isn’t that great because typically more than 95% of people aren’t even trying. #productivity “...most people can become (relatively) good at most things. ... The “one weird trick” is that, for a lot of activities, being something like 10%-ile among people who practice can make you something like 90%-ile or 99%-ile among people who participate. ... At 90%-ile and 95%-ile ranks in Overwatch, the vast majority of players will pretty much constantly make basic game losing mistakes. These are simple mistakes like standing next to the objective instead of on top of the objective while the match timer runs out, turning a probable victory into a certain defeat.”
