As does unionised dock labour.

There are no dockers any more. Just one man in a crane and containers 
everywhere

My brother-in-law was in the Merchant Marine as a deck officer. The switch 
to containers came early in his career. No more exploring foreign ports. 
Dock at 2AM, be off again by 6AM. While he had a master's rating he never 
sailed higher than 2nd mate, and then only for 6 months out of the year. 
The Masters, Mates & Pilots union was parceling out work in a dying 
industry. Dying for US flagged vessels, that is. I'd considered that 
career in high school as an engineering officer rather than a deck 
officer. Thankfully I went in another direction.

Yes. register your ship in Liberia and pick whatever crew you could get 
at below minimum wage.

Out of interest I looked it up. Crew on a large container ship can be as 
few as 10 and as many as 30, but no more than that.

Nice cheap way to push goods round the world

They will be nuclear in ten years, most likely

Jack London's 'The Mutiny of the Elsinore'  isn't one of his works on 
reading lists like 'Call of the Wild'.

london.html

He might be describing the crew of a Liberian vessel. The socialists would 
like to include London in their fold but they have to tread very lightly.

   Well, sometimes London sounded like a 'socialist'
   but really he wasn't. They can try to STEAL and
   BIAS his stuff but they won't be entirely successful.

   Alas the modern gens won't REALIZE the distortions ...
   in USA "history" is kind of forbidden now, you can
   ONLY teach the ultra-left 'truths' to the kiddies
   Or ELSE.

Instead of creationism...
TBH I see the USA more than any other country as bing torn apart by two 
different lies, while the truth dares not show its face...

The socialists want to appropriate everything popular. I wonder how they

   Loved the story a few years ago when they realized
   that all those huge cranes had Chinese cameras in
   them - which phoned home. Ergo the CCP could track
   ALL containers across the entire world :-)

   Sometimes the most effective spying is very subtle.

   Nothing obsolete about steppers.

   Nothing wrong with steppers ...

   Even a lot of current tech - in the end
   it's running steppers. It's how mechanical
   stuff gets DONE in a quasi-quantifiable
   fashion.

   Or do you think DC/PWM gets it done ?
   Done that - NOT especially precise.

   At some point, 'software' has to translate
   into 'real world'. Best Dreams don't work
   valves and machines at the water plant.

See other posts about my use of 'steppers'. I should know by now to be 
more precise.

If I understand correctly what steppers are, washing machines here have 
been using them till recently. My previous one had that.

It would make sense. A stepping relay with timer inputs could get the job 
done. My relationship with washing machines consists in dropping quarters 
down the slot. The really is one laundromat in town that is coin operated 
rather than a card swipe. It's something to do with 5 pounds of quarters.

I grew up with laced looms. Frankly a skilled operator can do them 
faster than tie-wraps, and cheaper. I can still lace.

I was a hair late for lacing. The last large control panels I designed 
used what we called Wiremold although I don't think that is the correct 
term.

He finally opens the door at around 1:50 and it looks like home. With the 
wiremold you could add or replace wires as need without messing about with 
a harness.

That is what we did. Often with solid core wires bent round nails driven 
into wood to identify branch points.

Solid core was best for fixed installations where the wires were 
soldered as they didn't have stress concentrations at the soldered joint

Then the loom was held down with cable ties - not zip ties - loops of 
plastic with holes at the end for a screw

Surprisingly cheap compared to today's prices for looms. Minimum wage or 
piece work by home workers in the consumer industry...serried ranks of 
nimble fingered Asian ladies on the shop floor for Mil Spec

(Flexible) PCBs today are cheaper.  I remember trying to get everything 
to mount off PCBs by the late 1970s...

The first company I worked for had the contract to make the harnesses for 
the company I eventually went to. The harness board consisted to two 4x8' 
plywood panels with a lot of finishing nails. 

The final connections would be made in the field, so a bundle of 
unconnected wires were left. Nobody wanted to come up short so I think 
everyone in the process added a 'little bit'. I went to the site with the 
VP of the company to do the pilot setup. There was about 5 feet of 'little 
bits' I cut off. The VP gathered up all the wasted wire to take home and 
ram up somebody's butt. 

When I went with the other company I designed in Amphenol connectors.

No tedious and error prone hookups on site.

   There ARE 'chips' ... or, cruder, boards with
   a lot of transistors.

   Anyway, the GOAL is to replace those big boxes
   full of mechanical relays ye and me both remember.

   That "PLCs" are being BLAMED for these hacks - now
   that's just bullshit. Modern PLCs are set up using
   modern software - and THAT'S what's being hacked.

   Never loved "ladder logic" diagrams. I've DONE
   it - in hardware and software - but it's not my
   favored perspective. Pref a more straight-up,
   logic-based, point of view. Yea yea, PLCs are
   "simple" and "rugged" - BUT .......

   IMHO, 'software' based PLCs are the only modern
   way to go. Alas that also introduces vulnerabilities.

   Industries NEED PLCs ... so much machinery that
   needs coordination/logic.

   Clicky-clicky-clicky ... DID kind of like those
   old boxes full of relays  :-)

   Anyway, are PLCs responsible for all these nasty
   hack in middle-America ? I don't think so. It's
   the all-ONLINE paradigm instead.

Semantics. A transition device was Square D's NorPak system. There were a 
number of different cards that that mounted in a frame similar to  a 
backplane. NOR gates are the simplest so those were the basic building 
blocks. Working with NOR, NAND, and NOT gates leads to brain bleed.

'Programming' was done by stripping wire, crimping on a tapered pin, and 
seating it with a too like an automatic center punch. Solid state relay 
logic...

   Modern PLCs do not involve placing wires.

   HAVE done that, but the new paradigm is
   more 'software" or "software defined"

   These cyber-attacks ... they seem to have
   been aimed at a specific, widely used,
   PLC/programmming paradigm. FAIR chance
   nobody changed the default passwords.

   Governments tend to copy OTHER nearby
   govts ... "State/County X uses THIS and
   thus this justifies US using X".'

   Been there, seen this from the bureaucracy.
   The IDEA is to cover their asses in case
   something goes wrong. "We just did what
   THEY did !!!". Yet another reason I retired.

   It's all M$ Fault regardless, not OUR
   fault !!!

   Anyway, it was interesting to see "PLCs"
   blamed. Sorry, it's NOT the PLCs but
   WAY up the chain.

   CyberIdiocy CAN destroy us.

   What happens when they get into the power
   plants, the NUKE power plants ???
