How does the compilation/linking process work?
...volved in calculating and building any addresses.
First we laying out the allocation of memory as best we can before we can know what exactly goes in each cell. We figure out the bytes, or words, or whatever that form the instructions and literals and any data. We just start allocating memory and...

...not safely pass-by-value
use of Eigen types as members requires special allocator customization (or you crash)

What are the differences between the threading and multiprocessing modules?
...faster to create and manage than processes (because the OS doesn't need to allocate a whole new virtual memory area), and inter-thread communication is usually faster than inter-process communication. But threads are harder to program. Threads can interfere with one another, and can write to each ot...

Why do x86-64 instructions on 32-bit registers zero the upper part of the full 64-bit register?
...rnatively 2), which I'm guessing happens with the 16 bit instructions, the allocation stage probably stalls (i.e. if the RAT has an active allocation for an ax write and an eax read appears, it stalls until the ax write retires).

Array.Copy vs Buffer.BlockCopy
...uffer from one or more severe technical flaws, including not moving memory allocations out of the test loops (which introduces severe GC artifacts), not testing variable vs. deterministic execution flows, JIT warmup, and not tracking intra-test variability. In addition, most answers did not test the...
