Why is it always the ones you most expect?

Alright, we need to do some research on this right away. How many dentists out of 10 actually agree his motives are unknown?

Fuck man, I wish Lemmy had different content warning descriptors. Like NSFW for nude stuff, NSFL for gore and NSWH (Not suitable when high) for stuff like this.

Nah I don’t think I’m fully charged yet, just one more quick little nap, then I’m good to go.

Please let me off this ride, it hasn’t been fun for 10 years now, please

Yes, normal people do this all the time when they are alone. Talking to ones self is pretty much an universal thing, especially when alone, but sometimes even when in company of others.

YSK this is actually a bad idea. By repeatedly damaging the skin this way you can actually trigger a nerve condition where the ends of your nerves just send pain signals all the time. People who work in professions where they scrub their hands a lot for their work are at risk of this. It’s probably fine to do every once in a while, but don’t make it a regular thing.

The chance is small, but I know a few folk who were real men when they were younger so they didn’t wear gloves when they really should have. Just don’t worry about it and scrub it off was the mindset back then and men wearing PPE were (and sometime are) seen as weak. But they describe the pain as getting stabbed in the hand repeatedly and wish they just wore the gloves.

The look on his face tells me you walked in on him mid-poop

+1 for FreeRDP, I use it all the time!

Neulich fuhr ich das Auto meiner Freundin und schaute beim Rückwärtsfahren nach unten. Großer Fehler, sie hat keine Rückfahrkamera.

They believe in eugenics, they are the worst of the worst.

I don’t think this has anything to do with ADHD, it’s just a little shortcut you can use when doing math in your head. I was taught techniques like this in school when we learnt addition and subtraction etc.

That’s not how AC works at all.

AC works by evaporating a gas, evaporation (going from liquid to gas) takes a lot of energy. By dong this inside a ribbed evaporator, the energy gets extracted from the evaporator cooling it down. Then a fan ventilates the air in the room over the evaporator, which in turn extracts the energy from the air. On the other side the AC has a compressor which turns the gas into a liquid. This takes energy to do, so the compressor puts all that energy in, heating up in turn. A large condenser (looks like a radiator) is used to cool the coolant down. The compressor puts in energy in the form of pressure, but as the gas is hot it can’t turn into a liquid. By cooling it down in the condensor it can turn into a liquid. A fan is used over the condensor to dump the energy from the gas into the outside air.

For gas in the past something like R134a was used, these days something like R290 (propane, but very pure/clean) is used which is better for the environment. In a very real sense ACs are energy pumps, they take the energy from inside and dump it outside. But they can also work the other way around, taking energy from outside and dumping it inside. This leads to pretty cool effects where you can heat your home with more than 100% efficiency. Because the energy you need to put in is only the overhead for pumping the energy, but the amount of energy being pumped can by much much larger. Over 100% efficiency in a closed system isn’t possible, but since an AC dumps the energy in the outside air it isn’t a closed system. ACs are also known as heatpumps for this reason.

The way an AC can be used to dehumidify is because of the dew point in the air. This is a combination of the amount of moisture in the air, the pressure and the temperature. When the AC pushes the temperature from above the dew point to below, the air can’t contain all the moisture it contains. This will cause the water to condens on the evaporator in the AC. This can (and probably will unless you are in a very dry area) occur during normal cooling operation. This is why there are normally lines to take the water and get it out of the AC unit. When the water would remain, it’s a breading ground for all sorts of nasty stuff (look up legionnaires disease), so it’s important to get it out of there. A lot of times a small water pump is used to pump the water away.

When cooling the AC tries to regulate the amount of energy pumped to keep a constant temperature in the room. Older/cheaper ACs just do this by start/stop, but better more modern ACs can regulate their power to prevent big swings in temperature and save energy. But when in dehumidify mode, the only purpose is to push the condensor below the dew point. Now the AC could do all sorts of fancy calculations to figure out the dew point and get it there. However that isn’t done at all, most ACs just push the temperature down as hard as they can. This is because the further you get down below the dew point, the more water condenses, so it gets the moisture out faster. And it’s also really complicated to calculate the exact dew point and get the measurements, because the AC itself influences the measurements a lot, so it would need sensors further away. Some big systems can do this and also measure the amount of moisture in the air and regulate to that. But small systems people have at home usually just go as hard as possible.

This is the reason why it just never stops in dehumidify mode and the air gets colder and colder. Nerds can probably get something cooking with sensors and homeassistant, but regular home systems won’t go to a target when in dehumidify mode. There are hard limits to how cold it will allow the condensor to get, to protect the system and prevent frost, but that’s not really the same as a target temperature in cooling mode.

Some better ACs also have a smart dehumidify mode, where it closes the inside unit, turns off the fan. Then cools down the condensor a huge amount. Then opens the inside unit and slowly blows air. This way it can get a lot of moisture out of the air fast and not cool down the air a lot at once. But in the end it’s the same effect. The energy still comes from the room, so the room will cool down, it will just not have huge swings in temperature.

That’s no news, I knew of Grant before he ever joined the Mythbusters. Sometimes I see something that reminds me of him and it saddens me to think I live in a world without Grant. That man made the world better, just by existing. RIP

There is only one thing to do: Call Jamie Hyneman and Adam Savage, get the Mythbusters back together and have them figure out if this is possible. I don’t care what it takes, it must be done.

Oops that was a typo, that should have been can’t

Who fucking cares at this point? Trump has done so much worse things by now. He can’t legally be president for a third term, so it’s not like it’s gonna impact his re-election. Most of the world already hates the man and think he is vile and disgusting. What is one pee tape going to change.

The pee tape could release today and be barely in the current news cycle. One camp will say “This just confirmed what we already knew”, the other camp will say “Fake news”. And tomorrow it will be forgotten.

No, it has to be something way worse than a simple pee video.

I remember when I was 15 living at my father at the time and my girlfriend was visiting for the weekend. I had to work on Saturday, but she wanted to stay over the entire weekend and would find something to do whilst I was gone. I told her to be free to use my computer.

We also had a couple of cats and one of them would always hang out in my room. Now this wasn’t your regular cat, this was a big boy. Not fat, just a huge bundle of muscles, big claws and huge teeth. We’re talking dog sized cat here. He was very sweet, but could be a bit playful and use his claws and teeth whilst playing. He was very careful with humans and tried to be gentle, but it could be intimidating for people who didn’t know him.

When I got home I found the cat sleeping on my desk and my girlfriend on my bed reading a book. I asked her how her day went, she pointed to the cat and said: “I wanted to use the computer, but that asshole over there didn’t let me.” Apparently what happened was the cat lay down in front of the keyboard, easily blocking the whole thing. And every time she wanted to type he would try to grab her hand and play with her. Being so large, she got scared of him and just didn’t use the computer. The cat declared victory and slept in front of the keyboard to celebrate, thus blocking the computer all day.

After she got to know him better, they got along just fine. He was such a sweet boy and never hurt anyone on purpose. You did need to be careful giving hem treats tho, T-Rex chomping off a hand comes to mind with that one.
