  • Unpopular opinion, but Tesla model 3 has been the best car with the lowest total cost of ownership.

    Electricity is cheaper than gas by a lot, no moving parts or fluids to replace except washer fluid, brakes last forever since it’s Regen braking.

    It’s also pretty fun to drive.

    Not a fan of the dude, and never bought into the hype on the tech side, but it’s a solid car.





  • I’m in tech and It’s literally not falling.

    People are still hiring, just the bar is no longer absurdly low.

    During the pandemic, everyone was hiring like crazy, and people coming out of boot camps were instantly hired even when they didn’t understand algorithms, didn’t understand system design, and didn’t understand engineering principles.

    Now, you actually need to have a brain to be hired.

    Tech is also not a bubble, because tech is in every single industry now. You might get froth in certain segments of tech (crypto, AI, whatever is the current “hot thing”), the market fundamentals are absurdly good. Operating margins of mature software companies are consistently in the mid 20s to 30s.

    It actually does get higher revenue for content creators for the majority of your creators. Average per view is something like 5-10x vs non premium views.

    It’s based around your watch time and something like 50%? of your subscription split across the channels you watch.

    Ad impressions pay very little on YouTube.





  • No, unless you are leveraging evaporative cooling, that amount of circulation isn’t going to get you much.

    Just get a real geothermal hvac system if you have the opportunity. Incredibly efficient.

    Back of the napkin conversion: 20btu/sqft recommended cooling capacity. 1btu = 252 calories (small)

    A 60k btu cooling needs

    15120000 gram degrees C of water. Assuming you have perfect heat exchanger on both ends, that’s 15120 liters-degrees circulated per hour.

    Pumping that much water alone is going to be quite a bit of energy.

    Then you have the problem of heat exchanger. There are lots of sizing mostly based on the deltaT temperature difference.

    Realistically, without some agent evaporating and recondensing, you’ll have a massive water to air heat exchanger that’s not practical at all.

    If you want to do more research yourself, heat exchanger sizing can be found in mechanical engineering and chemical engineering handbooks.
