I saw some documentary that suggested that they used to chip straight through fossilized feathers and skin to get to the bones because they didn't realise what they were.

I believe this is a thing in Quebec.

from https://culturalatlas.sbs.com.au/canadian-culture/canadian-culture-naming

In Quebec, the Civil Code requires parents to assign their child only one surname (either a single or compound surname) derived from their respective surnames. Compound surnames may not have more than two parts, with or without hyphens. Thus, a couple named Joseph BOUCHARD-TREMBLAY and Marie DION-ROY could give their children the surnames:

• BOUCHARD
• TREMBLAY
• DION
• ROY
• BOUCHARD-TREMBLAY
• DION-ROY
• BOUCHARD-DION
• BOUCHARD-ROY, and so on.

In Quebec, the law provides that spouses retain their respective birth names when they are married.

Continue to contribute meaningful content too. :)

We are part-way there. Some basic controls have been implemented. I don't want to get too specific as then they can set out to circumvent them. It shouldn't affect most genuine community members overly much.

Hi OP. I'm sorry that you were exposed to CP. Thankfully I didn't see it before it was purged, but I'm sure it was distressing, especially for someone who was a victim.

I feel that you post is important, but this is not really the appropriate community to raise it. Can you please re-post in support@Lemmy.world?

Many of them can only be controlled from a smartphone app that requires both the phone and the robot to access the cloud. ☹️

(…) cops have yet to ID a suspect.

Surely the could do it digitally?

In case it wasn’t obvious, ignore this suggestion.

Communities have to be nurtured and tended. Start posting content and see whether it grows. Be prepared for it to take a while though. People are still exploring and finding all the books and crannies.

To take my previous comment to the next level, have you ever put your finger over the end of an old-school bicycle pump and tried to push it in? If you have, you'll know that the pump gets hot. The reason is that you are not only compressing air, you are compressing the heat that the air has. This raises the temperature and we can use this phenomenon to move heat around.

Imagine you were outside where it was cool and you extended the bicycle pump and blocked the end permanently.

Then you went inside hour house and compressed the pump. The air (and heat) in the pump would be compressed into a smaller space, so it the air temperature of the air in the pump would increase. If you compressed it a bit, the air in the pump might go up to be the same temperature as the air inside your house. If you compressed it even more, it would get hotter than the air inside the house. If you then held it there, over time, the heat inside the pump would transfer through the wall of the pump to the air in your house. This would cause the air inside your house to warm up and the air inside the pump to cool down until they are the same temperature. In doing this you have taken the heat in the air outside, and released it inside.

If you then went back outside and allowed the pump to extend again, then the air would decompress and, because the heat previously left the air in the pump (when it was inside), it would get quite cold. Colder than the air outside. If you then waited again, the air in the pump would gradually warm up, drawing heat from the air from outside of your house. This happens because even though the air outside is cool, it's still warmer than the air in the pump.

Rinse and repeat. An air conditioner on heating mode, or a heat pump basically work in the same way. However, rather than using a bicycle pump, they have fluid running in a loop from inside to outside and back inside. The evaporator (outside the house) collects heat by allowing the fluid to 'expand' and cool below the ambient temperature outside. The condensor (inside the house) releases the heat by allowing the fluid to 'contract' and heat above the ambient temperature inside.

In this way, no heat is directly created from electricity. It is just moved from outside to inside. Believe it or not, this takes less energy than converting electricity into heat directly.

I've deliberately not talked about phase change here to keep it simple, that doesn't change the basic idea behind it.

It's basically because they don't directly convert electricity into heat, they just pull it in from outside. It still takes energy to 'push the heat uphill' from a cold place to a hot place, but less than directly heating.

It's almost as if stiffing his previous lawyers has made people wary. Strange.
