I'll take your word on the 130nm node matching, but I do recall when the 90nm node debuted, as I was in my university's electrical engineering program at the time. I also recall our professors (at least 3 different ones) mentioning that the new node label did not match any of the feature sizes. It seemed like they were all pretty irked about the fibbery.

When I saw a diagram of how the plug is designed, I don't see how lock wire would have helped. It looks like the bolts are threaded in from the interior side of the plane into taps in the door plug. These are probably steel bolts and I think it's a fair chance that the taps are aluminum, and these are oriented in the same direction as the outwards force. If the taps are indeed aluminum, all this put together pretty much guarantees the bolts are going to loosen up as the steel wears down the aluminum threads. The bolts should probably go all the way non-threaded through-holes, with the bolt heads on the exterior side of the through-hole, and lockwashers, nuts, and finally a lockwire on the interior side.

If the electrical provider says, "Sorry, we don't have enough line capacity where you want to build this," the project is dead in the water until the provider upgrades the lines and substations. The supply chain, even just for common items like pad-mount service transformers, is still backed up 12 months or so, and anything that falls under disaster repairs automatically jumps to the front of the line.

Adding new transmission lines is also terribly slow, not only do you have NIMBY problems, but some of the providers are basically bankrupt from lawsuits (i.e. PG&E) or probably will be soon (i.e. Hawaiian Electric Company).

On top of all this, some of these lines route through federally-owned substations (particularly DoD), and those substations need upgrades, too. Those federal substation upgrades compete for energy & utility project funds with initiatives like this one, which leads to a Catch-22 of nothing happening on either.

NFPA.org, free of charge. You're just stuck registering on their website and viewing the standards through their viewer that won't let you copy-and-paste.

Just so you know, anyone can register on nfpa.org, and view any of their standards online, free of charge. National Electric Code is NFPA 70. Being able to copy-and-paste is paywalled, however.

In the paper, they only tested this at the milliamp scale. While that could possibly help in something like a CPU, there's still a lot to go to see if this could remain valid for loads larger than a bathroom exhaust fan. Superconductors, even the cryo ones, tend to break superconductivity after the current reaches a certain threshold, and that threshold isn't always strongly related to the crossectional area, so "just make it bigger" doesn't always work, either.

Not addressing "precision munitions" in the above, as that is a vague term for a bunch of different guidance methods, propulsion (or lack thereof), and ordnance types.

Of the three, only long range artillery (and I'm using "long range artillery" as actual military jargon, here) has enough range where this could possibly be an issue, but weather and altitude (air density) affect it more. However, long range artillery is usually used for area targets, and if it's used for something other than terror-effect, there will be a forward observer telling the artillery battery how to adjust based on the impact points of the initial shots. Once the impact point is "good enough" a "fire for effect" is called for to saturate the area, typically with a battery (typically 6 guns) firing together as a unit.

The U.S. adopted what was then the Imperial wine (Queen Anne's) gallon of 231 cubit inches as the gallon for all liquid commodities. The UK gallon is a minor modification of what was originally the Imperial ale gallon, with the modern definition being based on the volume of 10 pounds-mass of water (with various stipulations of the exact conditions of measurement). Both systems define their pint as 1/8th of their respective gallon. A UK fluid ounce is literally one ounce-mass of water (under the same specific conditions as the gallon), these together yield the 20 fluid ounces to a UK pint. A U.S. fluid ounce is 1/16th of a U.S. pint, which is pretty close to the UK fluid ounce, but it's technically about 4% larger.

Note that there were two very minor revisions to the definition of an inch (and therefore the cubic inch) along the way, so there's also been some slight difference in size of the U.S. gallon over time.

Also, the U.S. dry gallon (not really used officially anymore: but dry bushel and dry pint still exist) is 1/8 of a U.S. bushel which is itself only a minor mod of the old Imperial corn ("Winchester") bushel.

In context, a rake is an attachment to a tractor, bulldozer, scraper, etc. (not the home garden tool). They used to be in common use in forest management to create firebreaks (preferably before fires happened). Also, having lived in the region, for part of the time period referenced (with friends and relatives still there), there are also lots of wild grasslands that used to be better managed with firebreaks and service roads, and also with a lot more livestock grazing (there used to be more sheep and goats). Many of the forest fires start as grasslands fires. There also used to be more active forestry with trimming off lower bows of conifers (which will droop branches all the way to the ground, it you let them), or even cutting down conifers entirely in broadleaf forrests.

I bought an Oculus Rift 2 a while back. It was fun, for awhile, but it was always a pain to clear enough space to safely use it. My home isn't terribly small, but it's not so big I can dedicate a permanent space for using it. I would imagine a large number of people who would like to have a VR headset just don't have space for it. Factor in inflation for necessity items (e.g. groceries), and it's easy to see why not so many people are planning to get one.

The skip returned about 6 months ago! One of my good friends is a CB & Ham guy and excitedly talks about it all the time. He frequently mentions things like, "It hasn't been this good since the '90s!"

They probably used a zone-controller system that had multiple zone controllers on each lighting circuit (i.e. more than one classroom per circuit breaker) and probably had the master controller fail. When the zone-controllers fail to receive a data signal from the master controller, they fail to an always-on state. Something similar can happen if something goes wrong with a data cable termination at any particular zone controller, because the zone controllers daisy-chain the data signal.

I just ripped out similar systems out of a couple of large buildings, and replaced them mostly with simple occupancy (motion) sensors with no data connections. If the one of the sensors or relay packs on the simple system fails, you replace just one broken part and it works again without affecting any adjacent light zone.

Circuit breakers are generally only designed for a fairly limited number of manual throws. When you manually throw them regularly, it can cause the overload trip to fail to do so when the circuit is actually over-loaded (which can lead to the wiring overheating and catching things on fire). There are such things as switch-rated circuit breakers, but they are fairly uncommon and usually have to be special-ordered.

While that is technically true, in facilities and maritime design conventions, "power circuits" is taken to mean "A/C power circuits other than lighting". Often, in a large enough building, there will be separate electrical panels just for lighting loads.
