How is TeamViewer so fast?
...y good implementation of x264 you get much better results with TV at lower CPU load. AnyDesk and Chrome Remote Desk use libvpx, which isn't as good as x264 (optimization and video quality wise).
However, I don't think TeamView can beat microsoft's RDP. To me it's the best, however it works between ...
Does pandas iterrows have performance issues?
... via SIMD instructions. Some parts of Numpy enable SIMD, depending on your CPU and installation process. The benefits to parallelism won't be as dramatic as the static typing and better caching, but they're still a solid win.
Moral of the story: use the vector operations in Numpy and pandas. They ...

Why main does not return 0 here?
...return value from a function is normally stored in the eax register of the cpu, so the statement "return 4;" would usually compile to
mov eax, 4;
ret;
and return x (depending on your compiler) would be something like:
mov eax, [ebp + 4];
ret;
if you don't specify a return value then the compil...

setImmediate vs. nextTick
...n completes.
So in a case where you're trying to break up a long running, CPU-bound job using recursion, you would now want to use setImmediate rather than process.nextTick to queue the next iteration as otherwise any I/O event callbacks wouldn't get the chance to run between iterations.

Scalar vs. primitive data type - are they the same thing?
