History
A light was first proposed for the shoal at Maryland Point in 1887, but an appropriation was not made until 1890. The original proposal was to construct a caisson light, but tests of the bottom convinced the engineers that a screw-pile structure could be made to work. The house was assembled at the Lazaretto Depot in the fall of 1892, and the light was first exhibited in December of that year.
The light was automated in 1954 and dismantled in 1963.
gollark: Because:- if they're not robust against these problems, then a leak of the network means you can meddle with cars- it makes it harder for new companies to enter the self-driving-car space- you would need some sort of really evil DRM scheme to stop people just... reading the neural network out of the car's computer systems- trusting your life to closed-source systems is problematic
gollark: Well, then that's ALSO bad.
gollark: BEE POLL!
gollark: Which is vaguely worrying for self-driving cars.
gollark: If your neural network is public, people could probably do !!FUN!! stuff like trick it into flagging regular stuff as evil offensiveness by tweaking a few pixels.
