Being somewhat adjacent to that with my work, there is a good chance anything in a critical area (hopefully fields like utilities, petroleum, areas with enough energy to cause harm) have decently hardened or updated equipment where it either isn't an issue, will stop reporting tread data correctly, or roll over to date "0" which depending on the platform with industrial equipment tends to be 1970 in my personal experience. That said, there is always the case that it will not be handled correctly and either run away or stop entirely.

Like I said it falls apart on its edges but for most people it's probably a better understanding of it than they will ever have or need, but most people scrolling thru Lemmy probably don't need to be understanding electrical concepts like electrons not actually flowing, charge, etc. I'm a controls engineer and while I am aware of the concepts and such, I am not designing electronics so at the end of the day I barely have a use for half of the concepts myself. Sure I could get down to the half semester class of quantum where things get weird, but that won't easily tell people to not to try to plug their fridge into a car battery
Clever, it just breaks down again with my analog of water volume lol. Definitely not saying it's wrong, I just like to leave it off so there are less questions haha
Another way to think of it is this: Volts are like water pressure (potential energy) Amperage is like the flow rate of water Ohms (resistance) is like how hard it is to push water from high pressure to low pressure Watts are like the volume of water (a unit of energy)
A big hose has low resistance, water can move freely A coffee straw has large resistance, it's hard to pull and push water thru it
A river has very low water pressure, and the speed of the water can vary, so volume of water moving can be huge so the flow rate of water can be huge as well. A pressure washer might have very high pressure, but use as much water as a kitchen faucet. Certain applications need high pressure, some need low pressure. A car battery is like a river, low pressure (typically 12volts) but move a lot of amps (cold cranking amps of up to 500-600 ish usually), and a wall outlet by comparison is like a pressure washer with 120v, 15A (in the US). A fridge won't play nice on 12v, it needs 120v. It might need 400 watts which a car battery can do but it cares about how it can get that by requiring higher potential.
A watt, W=VA, can be thought of as asking how much water is there? 1 minute under a sink verse 1 minute in front a fire hose has two very very different amounts of water.
A watt hour, which most people are familiar with in the US for billing on their utilities, is like asking how many cups of water an hour. A light bulb needs a fraction of a kilowatt hour, a drier needs multiple kilowatt hours, but might only run for 30 minutes.
This idea gets a little tricky and falls apart at its edges but as a general idea should hold up for most peoples understanding of electrical stuff unless you work with it daily like an electrical engineer, electrician or something similar. For sanity sake I'm not going to try to apply this to AC verse DC, I don't have a good analogy for that
Obligatory mobile formatting heads-up and what not and I'm not caffeinated so meh
Terraria!! Easy to understand mechanics, building, controller support or mouse and keyboard and can be run on anything
My brother in law has appendicitis, my 'rents have head colds, and I am still suffering from a 6 day sinus infection and COVID head fog from Thanksgiving but otherwise we're peachy
I would assume he's referencing the number of celebratory gunfire incidents. There are a lot of holes in roofs, cars, and every now and again people from people shooting guns in the air for celebration. There is a non-zero chance that one of those bullets will have enough power to do serious bodily harm. Scary as hell bc it can be some idiot within 3 miles putting lives at risk
American here and by no means an expert so take this with a grain or 1000 of salt. It's not segregation (at least not enforced any more) as much as a cultural thing. Many black churches likely started during segregation and the culture has definitely shifted over time which heavily influences things like music (look up soul gospel or soul music) and I believe tend to be more colorful in clothing and decor. There are aspects of elements of a service, and without a doubt influences on the topic of the sermon (thinking about it... Sermon might be a very Catholic word so I am not sure if that translates well). There might be some social do's and don't's that I don't know of as well but I don't have first hand experience
