Microsoft inks deal to restart Three Mile Island nuclear reactor to fuel its voracious AI ambitions
  • "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"

  • Filling the Solar System with AIR - What would happen?
  • 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.

  • JD Vance falters with Sun Belt swing state voters. They're more receptive to Tim Walz.
  • As they should be. Walz is a veteran, sensible and overwhelming attentive to his constituents compared to most political figures, a teacher, a coach, and genuinely wants the best for people. Not Democrats, not Republicans, but people. Why wouldn't you be swayed by somebody who has proven again and again they want the best for everybody in the limits of the situation?

  • What are some smaller things I can do to weatherize my home during summer?
  • Black out or light filtering curtains (tubular cellulose) can trap air in window frames. This is a fantastic insulator and will run you about 30/40 dollars a window or so. Additional, ensure the humidity of your home is ideal. It's hard to cool down damp air and will hinder your ability to sweat which will help cool you via evaporation

  • Trump blasts immigrants for taking jobs as he courts voters at a Black church, MAGA event in Detroit
  • 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

  • CFCs
  • 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.

  • This was the first result on Google
  • 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

  • This was the first result on Google
  • 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

  • Child dies after accidentally being shot in the chest at a target practice area
  • 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
