Discreet mathematique are the basis for computing
Not at the semiconductor junction level.
You are confusing computing with computers. Indeed, a "computer" used to be a human being implementing algorithms with a mechanical adding machine, and then were tube-based electrical systems, and in the future may use something wholely other than semiconductors; computing, however, remains the same. A bubble sort is still a bubbble sort.
I imagine the DOD would be a little peeved if it turned up in a Chinese shipyard.
We've probably outsourced worse( at least assuming that any more modernized systems, ECM, radar, etc. are stripped from the hulk first); but yeah, I'm guessing that the breakers offering the best rates don't exactly have security clearances, in addition to their atrocious environmental record, nonexistent occupational safety, and so on.
I don't actually know, and so would be interested to, is there anything considered 'sensitive' about something as old as a (presumably modernized here and there) Forrestal class? I assume that, for economic as well as security reasons, you'd rip out all the modern electronics, CIWS, radar, air-traffic-control systems, etc.; but is the remainder of the ship itself still considered a bit touchy, or old news?
Yeah but now you can pay out the ass for a 3d printer and download a wrench and wait 4 hours to get your wrench.
I'd be the first to make snide comments about some of the 3d printing hype (some of it, the sort that fails to answer "and we wouldn't do this with machine tools why exactly?", there are a number of genuinely impressive applications, albeit mostly involve additional finishing steps or the really expensive printers); but 'earth orbit' is one of those places where I can imagine being willing to wait for printing rather than ordering from harbor freight and waiting for shipping.
A problem better solved by standardizing fasteners, of course; but if somebody has already opened that can of worms for you, and you need an oddball tool in a space and shipping constrained environment, I can think of worse fates than using a plastic one.
For the first time in nine years I got to see my youngest daughter on Christmas; this is the first Christmas in nine years she didn't have to work. Great Christmas present!
And the second to last pre-publication copies came Christmas eve eve. I finished going through it this morning, and the book itself is ready. What wasn't was the cover; I fixed it and ordered another copy, so Mars, Ho! should be online in a couple of weeks.
