  • I get that, but outside of using aux heat or having to defrost the coils outside, it seems like identical temp differentials would be identically efficient. The heat pump doesn’t use more energy to heat than cool, the heat pump uses more energy in winter due to a larger difference to overcome.

    Edit: I believe successfultry’s comment below is the most accurate. Heating is more efficient than cooling, not vice versa, due to waste heat not being a waste for heating.


  • Why would they use more energy in one direction versus another? This doesn’t really make sense to me. Heating and cooling is just swapping which element is the condenser and which element is the evaporator.

    Edit: assume I’m talking about identical temp differences. I’m aware it gets more cold than it gets more hot, but that’s not comparing like for like. My question isn’t “is it more efficient in summer or winter” it’s “is cooling more efficient than heating.”



  • You don’t need a job you love, hardly anyone gets to do that. It’s amazing if you can, but a job you can tolerate is really all you need. Keep your eyes open for opportunities, take them if it feels right. Trust your instincts.

    Save some money. Having a bit of financial freedom can drastically help you with having flexibility to do different things, and you need to do lots of different things to figure out what you like.

    You will have to sacrifice comfort at some point and take some leaps into the unknown when the opportunity presents itself.

    Most of all, get out of your hometown. The single biggest influence I’ve seen on people turning out great or people getting stuck in their ways is experiencing different things. College can get you part way there, but travel and living away from your hometown, especially if you can swing something international for a while, can help you immensely.






  • I’d argue that it’s very important, especially since more and more people are using it. Wikipedia is generally correct and people, myself included, edit incorrect things. ChatGPT is a black box and there’s no user feedback. It’s also stupid to waste resources to run an inefficient LLM that a regular search and a few minutes of time, along with like a bite of an apple worth of energy, could easily handle. After all that, you’re going to need to check all those sources chatGPT used anyways, so how much time is it really saving you? At least with Wikipedia I know other people have looked at the same things I’m looking at, and a small percentage of those people will actually correct errors.

    Many people aren’t using it as a valid research aid like you point out, they’re just pasting directly out of it onto the internet. This is the use case I dislike the most.
