If you rotate the hinge to angle X above the horizon, light coming in from an altitude angle of 2X (=zenith angle of 90deg-2X) will get reflected to into horizontal rays inside the tube.
So you don’t need a mount with adjustable altitude angle - the hinge accomplishes that.
Yeah, the four color problem becomes obvious to the brain if you try to place five territories on a plane (or a sphere) that are all adjacent to each other.
I think one of the earliest attempts at the 4 color problem proved exactly that (that C5 graph cannot be planar). Search engines are failing me in finding the source on this though.
But any way, that result is not sufficient to proof the 4-color theorem. A graph doesn’t need to have a C5 subgraph to make it impossible to 4-color.
Think of two C4 graphs. Choose one vertex from each- call them A and B. Connect A and B together. Now make a new vertex called C and connect C to every vertex except A and B. The result should be a C5-free graph that cannot be 4-colored.
Did you choose components and plan the connections on the perfboard yourself?
Also what was the original like? Would things work if you replace for example the transformer input side either the new kit and keep the output side the same?
Anything that’s updated with the OS can be rolled back. Now Windows is Windows so Crowdstrike handles things it’s own way. But I bet if Canonical or RedHat were to make their own versions of Crowdstrike, they would push updates through the o regular packages repo, allowing it to be rolled back.
If I give you the entire real line except the point at zero, what will you pick? Whatever you decide on, there will always be a number closer to zero then that.
Does any GNOME user here use X11? On my computer I have been exclusively using Wayland for 3 years. It's great.
Slightly concerned about remote desktopping though. What do I replace xrdp with?
