An old way to check for live steam leaks is to hang a rag from a broomstick. The steam is quite capable of cutting as well as burning the rag.
3000 psi oil and hydraulic leaks can certainly cause injury by injecting oil into flesh and sometimes cutting. Hydraulic and diesel (injector lines are high pressure) mechanics have to be aware of this when troubleshooting.
I don't take notebooks I care much about when travelling so I've no concern if they get banged about or stolen. It's so easy to wipe and reinstall before travel that one should do that if you don't want your goat porn viewed by the Stasi. I'm not worried about Uncle Sugar reading anything I have because I don't do anything interesting to the State and if I did I'm not stupid enough to want to use a computer for it. AT ALL. If for some reason I had to carry vital legal-but-proprietary commercial information it takes little effort (well, on Thinkpads anyway) to stash a MicroSD card temporarily glued under the label of a WLAN card or a section of heatsink.

What many working class students tend to ignore is that lack of education can leave them not only intellectually disarmed, but poorly equipped for the trades they often aspire to. The days when you could be illiterate yet make decent money in the trades are over. Now community colleges are tasked with repairing what was ignored during high school.
Many people reject science and education in general. Make no mistake about that.
I had the misfortune of attending school with such trash (until rescued by boarding school), and rejecting science was the least of their problems. Such folk are why schools are Hellmouths. They are stupid, base and want to stay that way.

F150s have had an aluminum hood since the 1997 model year. No problem, and no rust. (I have a '97 and a 2000 F150 and have wrenched on many more.) Plenty of those on farms.
Land Rovers survived African use (farms included) where presumably users beat the shit out of them as they would any other truck.
Modern vehicle body "repair" is mostly "component replacement", but if you need to you can certainly MIG weld aluminum. If one may judge by the kickass custom tool and equipment fabrication shown in magazines such as Farm Show, farmers will take it in stride.
Service and flatbeds would of course be steel, and those are aftermarket anyway. An aluminum cab wouldn't be an issue.
Only the ruthlessness of an Ataturk and the military which succeeded him can bring modernity and secular order to move such an Islamic country forward. Turks rightly admire Kemal Ataturk, but unless enough are willing to pick up a gun they will become prey for the fundamentalists. Theocratic superstitions (all of them) are only able to see democracy as a stepping-stone to their takeover of the State. Those who would resist superstition had better be willing to kill for their freedom. Ataturk and the Young Turks were willing, and they made tremendous progress. We shall see if that progress will be reversed. http://en.wikipedia.org/wiki/Mustafa_Kemal_Atat%C3%BCrk
Union trades have enough trouble with rats because so many tradesmen think they are special snowflakes. (Some are.)
Good luck with the cat herding, especially in a physically comfortable field such as IT which can be far more easily outsourced than physically demanding and manually skilled trades such as pipe welding.
Technically true, but unless someone is targeting your specific machine it's doubtful that would happen.
You could also boot off CF card in an adapter after modding the adapter to disable writes. Any changes to the CF could be done using a different adapter.
These CF cards are available with a write-protection switch:
"I own two machines which cannot be upgraded for very good reasons."
What are those? I support a couple of XP machines for a friend who is content with his old CAM software because it does what he wants and the post-processor works with his old Fanuc control, but they no longer connect to the internet. Cut the cord, problem solved.
"I presume you don't live in quake country, or it would be preferable to leave them separated."
Their "foundation" is gross overkill heavy section ten-inch steel I-beam across the ends, resting on railroad gravel. Welding (not to "quake country" structural codes which specify a different wire nowadays) was done with stick (6010 root pass) then E71T-11.045" flux core wire. Top corner fittings are welded together and the splice strip itself is thicker than the ISO roof skin and adds considerable strength. Since the beams themselves are unanchored, they are free to float if my area ever has a serious quake. I did it that way because if the shop ever settles after I add weight in machine tools (unlikely with railroad gravel) I can jack a corner easily.
I personally like ISOs, but they are just steel boxes and there is more to building with them than meets the eye. Po' folks in the US didn't do well in "the projects" and even more spartan ISO construction is unlikely to take off for warehousing them. Even for the "homeless" you'll need wiring, insulation, plumbing, sprinkler systems, HVAC and waste disposal, as well as security and surveillance so they don't prey on each other quite so much.
Remember this has all been tried before, sans ISOs, many times! Technical solutions to social problems with (initially) lavish funding were applied, and the result eventually turned more socially toxic than dispersed poverty.
By all means do an ISO structure for yourself. DIY economics can favor ISO construction and not stacking them slashes cost because you don't need crane rental. DIY homes are owned by people who have a personal buy-in to making them work. Modern insulation panels, spray foam, and so forth make ISOs practical in any climate. Adroit scrounging and human networking can turn up lots of quality material for free. They are fun to work with and complementary steel building kits (galvalume beats the shit out of Corten, but ISOs aren't expected to last decades without refurb as they are designed to be expendable) can integrate and protect them. I have a Steelmaster (there are many companies making the same rolled steel panel designs so shop around) building and would not hesitate to use their kits over ISOs. Two people with scaffold and pneumatic tools can erect one if you aren't in a hurry. See Youtube videos for various methods. I anti-seized the bolts and only had to cut a few when I tore mine down for relocation.
Do get High Cube ISOs. The standard height version limits air circulation and has little room for vertical storage or lofted furniture options.
Lots of container info and useful parts such as corner clamps and twist locks. You could prefab end beams with weld-in twistlocks offsite then connect your ISOs to them, and to each other at the top with corner clamps if you want the option to demount and move them yet want "earthquake resistance" for your structure:

The internet is a military invention. Don't use it for secure comms and never want to use it for secure comms.
No electronic comms are truly secure against a well-funded attacker.

The way to deal with exposure is not to use insecure communications for information which must be kept secure.
There will be much thrashing as users attempt to get secure outcomes because people are hard-headed.

If it weren't fun to ratpack and destroy people of enemy ideologies, it wouldn't happen.
In particular, stupid people who publicly expose themselves through vanity use of social media are seen as lulzworthy targets.
