Oh I see, that is odd. I thought your background was yellow beforehand. Is it perhaps plasma’s Night Light? That will tint everything yellow when it’s enabled.

New plasma update sets the accent colour from your background. To change it go to System Settings > Colours and Themes > Colours (not sure if Mint has it in the same place) then set the accent colour you like from the top.

Torvalds just really dislikes C++. He’s gone on the record saying that he thinks it’s just not a good language. In his own words “C++ is just a waste, there is no design at all, just adding some scum on top of C.”

There’s a whole bunch of mechanisms, largely depending on the fusion architecture and the atoms being fused. For tokamak reactors the circular nature lends itself well to what you describe, though usually it’s energy being imparted into the ions to keep them contained and away from the walls. In the ‘standard’ deuterium-tritium fusion model (the easiest to perform) fusion produces a helium nucleus and a neutron, where the neutron gets most of the energy. Since a neutron can’t be contained by magnets it impacts the chamber walls. This heat is wicked away by, you guessed it, cooling water which turns into steam. In order to use a direct energy conversion strategy you need a fusion reaction that produces no neutrons, but we’re not there yet.

Some types of fusion can bypass steam generation and use what’s creatively called Direct Energy Conversion. If the fusion products are charged particles they can be passed through a magnetic field to separate them based on charge and collected onto plates. When you look at the electric potential between the plates you’ve effectively created a voltage, no steam necessary. It’s also theoretically possible to do the same with some types of fission products too.

As other people have said, oozing. In addition to their fixes I would suggest looking into sequential printing as a print method to be aware of. Rather than printing two objects layer-by-layer, sequential printing will complete all the layers of one object before starting on the next. This has the major benefit that you get zero oozing or stringing between parts. This can be a lifesaver on materials like PETG that will always string to some extent. The only gotcha is that you have to place the parts further apart on the print bed, as the extruder will collide with any nearby completed parts (Prusa slicer has all of this built in, including alerting you if any collisions would occur). I don’t recommend it for every print, but it’s a useful tool to have in your toolbox.
