Mid 1990s, trying to learn about Linux, I was influenced the most be a news
report of a Linux box working more than a year at sea without down time...
for an oceanography project.
Hull work is just the average day routine, average chore, work for a mariner
is a way of life... Scraping benthic organisms from the hull is more work
than applying protectant. Having cut thick sheets of alum to cut through the
hull, to swap props for jet turbines to fix a design flaw, was a great deal
of work. Engineering mistakes early will be revealed downstream during
maintenance. I imagine the desired chassis for the data island might be
modular with redundant parts, the fewer unique parts the better.
I wonder what their flag will look like.
