the machine soon after had a hard lock. also hotplug "thought" tulip
was loaded. which it kinda was, totally inoperable. by this i mean i
couldn't bind an eth2 to it even if i wanted to do that.

"I believe that part of what propels science is the thirst for wonder.  It's a
very powerful emotion.  All children feel it.  In a first grade classroom
everybody feels it; in a twelfth grade classroom almost nobody feels it, or
at least acknowledges it.  Something happens between first and twelfth grade,
and it's not just puberty.  Not only do the schools and the media not teach
much skepticism, there is also little encouragement of this stirring sense
of wonder.  Science and pseudoscience both arouse that feeling.  Poor
popularizations of science establish an ecological niche for pseudoscience."
