Tbh it starts to look better to just define a constant and comment it.
Well.. if (waterPressure > MAX_PRESSURE_BEFORE_YOU_FLOOD_THE_WHOLE_TOWN_OF_IPSWICH_AND_CALNE) is pretty self-documenting. No comments needed.

...what the code does, not why it does it
This is my issue with "it's self documenting code!". I'm a maintenance coder. I deal with people's code long after they're dead (or ragequit). Some are for control systems.
if (waterPressure_psi > 500) raise PipeMayBurstException. Okay, we're dealing with water pressure, in psi unit, and if it's too high, it may break the piping. Self documenting!!
Except that our pipes are rated for 1000psi. SO WHY THE 500?! Do we have one or two sites - out of hundreds - with lower rated pipes? I can double performance if we raise the threshold to 700, well within the safety tolerance, but AM I GONNA KILL SOMEONE when they upgrade to our latest controller??
Honestly, the joke landed anyway. I've done numerous uppercase-Q trying to quit, because I didn't let go of Shift fast enough after typing the colon...
The meme refers to the old adage "C lets you shoot yourself on the foot. C++ lets you shoot both feet and gives you a shotgun to do it" - referring to the how C allows you to perform memory-unsafe operations (causing corruption, or worse, security vulnerabilities), and C++'s complexity, potentially obscuring such unsafetyness.
Rust's memory safety tries to save you from doing (un)intentional bad stuff, by giving you compile-time errors. It's also the bane of everyone so used to C/++'s ability to just pass around and modify whatever memory they want.
"Mark works for MS" is a massive understatement. He's CTO of Azure now.
And speaking of Sysinternals, arguably the most exciting update was when ProcessExplorer got a dark mode late last year :)
Those were the times when I had to pull out my hard drive, ride my bike to my best mate's house, and plug it into their PC so I could finish up a report due the next day. All because Windows 95 didn't shut down cleanly and refused to boot.
