I think it specifically applies to implementing standards that are known to be more difficult to implement and easily break.

I'm sorry, but this is such an extreme example. You should not overdo anything, be it meditation, gaming, playing, reading, any sport, even drugs. Drugs also give you a state of mind that, when taken to the extreme, can harm your social life and well-being. That is not a problem specifically of meditation.

You can safely do anything up to the point that it benefits you. The moment your well-being suffers, or you neglect important parts of life, like friendship, you should stop.

ReactOS has nothing to do with ReactJS.

That's a great way to put it. I had a few depressive episodes in my life, I know that these thoughts and feelings are symptoms. The inability to feel, even the hopelessness are symptoms of the disease. Usually, I can even pinpoint the cause of the episode. But another symptom is the inability to imagine a state of mind without depression. And no matter how rational you are, it is very difficult to believe in something that you cannot imagine.

My x86-assembly has become very rusty, but couldn't it work like this, not using a branch:

(with eax being the unsigned 32-bit input word)

  xor ebx, ebx
  test al, 7
  stnz bl
  shr eax, 3
  add eax, ebx

(edit: replaced a movzx with an xor)
