Give the demo a try. I compared the CPU usage to the win10 file explorer, and they look identical (both are minuscule); it's super impressive.

Yet these "lower-level" APIs, DX12 and Vulcan, often don't significantly out perform DX11, and in many cases DX11 performs better. I put lower-level in quotes because those APIs bake assumptions about the hardware into their

I find it sad that this paper mentions two valid critiques of OOP[0][1], yet makes no effort to engage with their specific criticisms. Also, citing Microsoft's COM object system as _the_ example of OOP's great success must mean th

The issue with those books is that they don't have any concrete data that affirms that they are worth following. And, in fact, that style of code is largely to blame for why modern software feels so sluggish. They often reduce performa

For those not familiar with the author, this is Daniel Lemire, a high performance software expert. He has done lots of work about squeezing as much performance out of a CPU as possible; see his work on SIMD JSON parsing[0]. I imagine he wro

No, I think exploratory programming is exactly that. Solutions to a problem is the very thing to be explored.
