This diagram is wrong on so many levels. Ozone is “charged Oxygen” (O1 rather than the usual O2) so it’s saying you get Ozone out of the Hydrogen side. The bubbles are forming in a place where they can’t get to the output vents, so the accumulating gases would slowly force the water level in the inner chamber down, and thus up through the vents. It’s pretty shit. Is it AI slop?

NPM is not a Linux thing - it’s to do with web applications, so it works on Windoze and Mac too.

It didn’t quite work like that. They used to arrive boxed in batches. The keyboards were worth about £100 back then - so would be worth a lot more in today’s money - and they were looked after with care whilst in transit. It was the end users (in offices) that put the gunk there.

Can confirm. Back at the beginning of my IT career (mid 1980’s), I worked as a temp for a computer manufacturer in their refurb repairs department. In those days, kit was so expensive that everything got repaired if it went wrong, and one of my jobs was repairing keyboards - PC keyboards, and dumb terminal ones - and the first part of the process was stripping and cleaning them. There was a lot more room for crumbs and dust back then, too, and man did they get full. Crumbs, staples, paper clips, hair grips, all sorts. I had literal mould growing in some of them. I remember the ones coming in from Italy were the worst for that for some reason.
