my unpopular opinion:
this is not evil: (float)x
this is: static_cast<float>(x)
too much typing, too much to read, no benefit

Win11 no longer allows to create new text file from context menu. Seriously? "Show more options" has the same choices. My workaround was to create a Publisher Document, rename it to some text format like .hlsl or .txt, delete the binary crap and start typing but it made me sad.

It took my a while to understand why GPU ray tracing is faster without back face culling. Seems the fast path cannot do the test so it needs to do extra work. I expected the test to be part of the ray triangle intersection.

Memory layout that provides:
Deterministic memory map behavior,
Single-cycle allocation speed,
Regular C object life cycle for objects that need it.
This makes it very suitable for games.
