Of course not. There is also hair styles, acessories, and makeup… I meant beer, football, and boobs.

If you are using the concepts and writing the code yourself, you’re fine. If you are copying/pasting code from work to your personal project, you’re commiting IP theft. I’d recommend never doing that. On the otherhand, if it is for a peraonal project that you will never give away or sell, no one will know. Id still recommend not doing it, but to each their own.

AC as refrigerant, not coolant. Although that might be semantics.

AC is a type of heat pump. You are moving heat from inside to outside. The physics behind a heat pump, is fairly simple. There are three principles to work with.

1. Take a gas, compress it, and it gets super hot.
2. Take a compressed gas, let it rapidly expand, and it gets super cold
3. Different temperature gases move from hot to cold

Let’s focus on AC since most folks are used to that concept. In an AC, you have a closed loop of refrigerant. Outside, there is a compressor that compresses the gas, which makes it very hot. The gas is pushed through a radiator with a fan pulling air through it. Since hot moves to cold, the heat trapped in the gas moves to the outside air, and the gas is slightly cooled. (As long as the gas is hotter than outside).

Inside, there is an expansion valve that lets the gas rapdly expand, making it super cold. It is pumped through a radiator that has inside air blowing over it with a fan. Since hot moves to cold, the heat in the inside air moves to the cold gas, cooling the inside air. (As long as the gas is cooler than the inside temperature). It is then pumped outside to start the loop again.

So, inside gets cooler while the heat is moved outside. The physics also establishes the limits of the heat exchange. You will only grab heat from inside if the expansion makes the gas colder than the air inside. Typically it expands to around 0 degrees. Likewise, it will dump the heat outside if the gas is hotter than outside air. The compressor typically makes it 130 to 140 degrees (temps vary depending on many factors).

To use a heat pump for heating rather than cooling, reverse the process. Pick up the heat from outside and dump it inside. This will work as long as outside is warmer than the expanded gas (0 degrees or so). Although you can get some that go to around -20.

Over time, the weaken your muscles and make it even more difficult to have good posture. You end up relying on the straps rather than your own body.

More of a physical representation of a debt, but in essence, yes.

I buy a rock from you with $5, that $5 represents the debt I incurred by taking the rock. You have the $5 that you can use to barter for something else. At the end of the day, the government is backing my debt for the rock with a physical piece of paper. Except it isn’t physical anymore now that everything is digital. So, I suppose its more like the bits of data that represent the physical money that represents the debt for the rock is backed by the government. Although that money is actually physical at the bank that conducted the electronic transaction, and they borrowed that physical money from the fed. But even then, it is inflated since not every dollar a bank transacts with, is backed by something physical since the reserve ratio is not 100%. And that is when it starts becoming confusing.

I agree that it isn’t as good as it was. The last two updates have definitely decreased its effectiveness for multiple things, not just dev. It is still my starting point when looking for something. It is just not as good as it used to be.

Obviously, you can’t take what it gives at face value, but you shouldn’t do that from SO either. In general, I see faster results using GPT than I do with Google and SO. You can also extend the responses with any customization or changes specific to what you are trying to do, where you can’t with SO.

I’m not saying SO is bad. Not by any stretch. I still use it a lot. It just isn’t my starting point anymore.
