Map Tiling Algorithm
...late as a grid. We know the points on the grid at constant temperature. We set the temperature of all unknown points to be room temperature (as if the vent had only just been turned on). We then let the heat spread through the plate until we reach convergence. This is done by iteration: we iterate t...
Is [CallerMemberName] slow compared to alternatives when implementing INotifyPropertyChanged?
...e can check that with any IL disassembler (like ILSpy) : the code for the "SET" operation of the property is compiled exactly the same way :
So no use of Reflection here.

kernel stack and user space stack
...rspace stackpointer to be valid nor usable, and therefore will require one set under its own control. Different CPU architectures implement this in different ways; x86 CPUs automatically switch stackpointers when privilege mode switches occur, and the values to be used for different privilege levels...

Why doesn't C# support the return of references?
...y-accessor of a value type:
public struct Point
{
public int X { get; set; }
public int Y { get; set; }
}
and now create an array of that struct:
var points = new Point[10];
points[0].X = 1;
points[0].Y = 2;
In this case points[0], the array indexer, is returning a reference to struct....
What's a correct and good way to implement __hash__()?
...on will not cause one object to replace another when used as a dict key or set element as long as the objects do not also compare equal.
Outdated/bad solution
The Python documentation on __hash__ suggests to combine the hashes of the sub-components using something like XOR, which gives us this:
