“is usually written by an over worked engineer”

I’m in this post and I don’t like it.

But really these scada systems are rarely well defined by the time implementation happens. Often the architect has a great plan, but by the time it’s passed to a manager, a non-software engineer, to the product engineer to the automation team to the contractor the end result is “X data is pushed in With Y form and we use either a,b,or c date time stamp any nobody knows”

Well, it wouldn’t change the gravitational field of any given planet so the atmospheres around planets would exist still but they might become more air saturated. The other thing to consider is that since this air would be so far away from the gravitational fields of many planets that it would actually get pulled into the sun over time, increasing the mass of the Sun and further accelerating the collapse of the solar system. By how much I could not tell you, but eventually the extra mass being dumped into the vacuum of space around our solar system would increase the mass of our star.

Minnesotan here, been very pleased with the direction of policy and commitment to constituents he’s had. Bummed he won’t be the gov when he’s VP but that’s just me being a little selfish.

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
