You lost me in the last sentence. I think what you said rings true with an exception. I don’t believe that the people you’re referencing will bother with learning how to care again. It would be a tacit admission that it was willful ignorance.
This one has been easy for me lately: They spell ‘lose’ as ‘loose’.
Good points, 12 seems to be superior and I’ve changed my opinion.
I’m not experienced with RPN but at a glance think there’s a solid argument for it.
Base 16 is superior and once you learn binary math, easier to divide and multiply.
There actually is an array in any POSIX shell. You get one array per file/function. It just feels bad to use it. You can abuse ‘set – 1 2 3 4’ to act as a proper array. You can then use ‘for’ without ‘in’ to iterate over it.
for i; do echo $i; done.
Use shift <number> to pop items off.
If I really have to use something more complex, I’ll reach for mkfifo instead so I can guarantee the data can only be consumed once without manipulating entries.
