tp34··on We put half a million files in one Git repository (2022)
What is the "standard linux file system"?

ext4 on an old system, feeble in comparison to yours, performs much better.

ext4, 8GB memory, 2 core Intel i7-4600U 2.1GHz, Toshiba THNSNJ25 SSD:

$ time ls -U | wc -l 555557

real 0m0.275s user 0m0.022s sys 0m0.258s

stat(2) slows it down, but sill this is not as poor as your results:

$ time ls -lU | wc -l 555557

real 0m2.514s user 0m1.126s sys 0m1.407s

Sorting is not prohibitively expensive:

$ time ls | wc -l 555556

real 0m1.438s user 0m1.249s sys 0m0.193s

Drop caches, sort, and stat:

# echo 3 > /proc/sys/vm/drop_caches

$ time ls -lU | wc -l 555557

real 0m6.431s user 0m1.249s sys 0m4.324s

tp34··on For many home-schoolers, parents are no longer doing the teaching
> In home school, there is less people and more choice.

I think you meant "there are fewer people." Were you home schooled? Perhaps public school English would have been a better option.

tp34··on A Modern C Development Environment
> And if you're running on Linux atleast, there's literally no overhead (containers are just processes tagged with C-groups, after all).

cgroups require code to implement. This is overhead. "Literally" is not the word you should be using. Perhaps "little" overhead or "minimal" overhead?

tp34··on Automakers are starting to admit that drivers hate touchscreens
Do you need to look at your computer mouse to "click" the button(s)?

Assuming you possess this basic competence, I find myself wondering how you managed to purchase a vehicle with such absurd ergonomics.

You have a strange, poorly designed vehicle

This "big dashboard full of buttons." Please provide a picture. Is this a custom design?

"For me, when things get dangerous, its [sic] when pressing the button (physical or touch) doesn't do what its [sic] suppose [sic] to do."

What actions are you referring to? Changing the audio volume? The interior fan speed?

You may want to consider researching your vehicle purchases more rigorously.

tp34··on Why Perl?
Translation:

I am not a competent $language programmer. You will not understand my poorly written code.

In this case, language="perl".

perl is not special in this regard.
