I remember hearing about System76 a while back. They manage Pop!_OS which comes preloaded on their stuff. I don’t know much more than that. If you are mainly looking to replace your laptop because you don’t want to switch to 11, you could always try out Linux on it with a live USB. Basically you format a thumb drive to act as a boot drive. There are resources online on how to do it and it’s pretty simple. It doesn’t mess with your current install. If you like it, you can fully install it later.

It’s more than just a water level issue. As I understand it, the Amoc is responsable for warmer water cycling up to the coasts of western Europe resulting in warmer temperatures than they would normally get at that latitude. It would change the temperature and weather experienced there. Hank Green did a video talking about how it could potentially affect Ireland about a month ago.

You can also spike the brain of the fish. There’s stuff online about Ikejime which is supposed to be a way to quickly kill the fish to improve the quality of the meat. There’s resources online about it.
