ZFS has open my eyes to /dev/disk/by-id/. It's the only way when you have many of the exact same make/model/size drives per machine. You will learn by fire the first time you need to determine which drive you need to replace.

Agreed. I get the intended result of 7 5 7 on macOS 10.13.6 LLVM.

  Mac:tmp $ clang -O3 mem1d.c ; ./a.out
  diff = -96
  x = 0x7f9f4fc00300, *x = 7
  y = 0x7f9f4fc00360, *y = 5
  p = 0x7f9f4fc00300, *p = 7

  Mac:tmp $ diff mem1d.c mem2d.c 
  13c13
  <   int *p = (int *)(yi + diff);
  ---
  >   int *p = (int *)(yi - 96);

  Mac:tmp $ clang -O3 mem2d.c ; ./a.out
  diff = -96
  x = 0x7fc2b5c00300, *x = 7
  y = 0x7fc2b5c00360, *y = 5
  p = 0x7fc2b5c00300, *p = 7

  Mac:tmp$ clang --version

You only pasted a clang run here. It's gcc that's supposed to give 3 5 7.

What about the requirement to run signed code from power on?

For anyone interested, there is a video on Amazon Prime called The Science of Fasting 2016.

Just watched it and was really unimpressed. For a documentary titled "the science of fasting" they really went out of their way to find the least credible sources and seemed to try appeal as much as possible to consumers of alternative and holistic medicine. Secret, untranslated texts by open-minded Soviet researchers, Western science rejecting studies out of a bias against unprofitable treatments, genetic memories of starving on the savannah, body resets and cleansing...I know a lot of people who are into fasting would really like that stuff, but I was hoping to find a description of fasting that avoided those sources.

GRC still has a utility for click of death.

What happened to the other 16 threads?

18(core) * 4(cpus) * 2(+ht) = 144

Some fraction has to go to the physical host for its resources.
