Similar story for our youngest - excuse after excuse. We just bought two round-trip tickets to Warsaw and paid privately. It was a little more but my wife and son got to spend time with friends and family for that extra. The effort we had spent in US we never got back. I hope it worked-out okay for your family as well.

That's why you can't understand.
I wonder how, if at all, you can improve precision with 4 stratum-1 clocks like he author has.
I miss the days of knowing who last touched every source file and precisely what version it was:

WHAT(1) General Commands Manual WHAT(1)
NAME
what - show what versions of object modules were used to construct a file
SYNOPSIS
what [-qs] [file ...]
DESCRIPTION
The what utility searches each specified file for sequences of the form
"@(#)" as inserted by the SCCS source code control system. It prints the
remainder of the string following this marker, up to a NUL character,
newline, double quote, `>' character, or backslash.
The following options are available:
-q Only output the match text, rather than formatting it.
-s Stop searching each file after the first match.
EXIT STATUS
Exit status is 0 if any matches were found, otherwise 1.
SEE ALSO
ident(1), strings(1)
STANDARDS
The what utility conforms to IEEE Std 1003.1-2001 ("POSIX.1"). The -q
option is a non-standard FreeBSD extension which may not be available on
other operating systems.
HISTORY
The what command appeared in 4.0BSD.
BUGS
This is a rewrite of the SCCS command of the same name, and behavior may
not be identical.

You'll probably dislike this too:
$ {
> echo foo \
> && echo bar \
> || echo baz ;
> }
foo
bar
<^P><^A>$<^F>IFS
${IFS# echo foo && echo bar || echo baz ; }
$ _
$ foo |
bar | # ?Do? *the* $bar$ && [do] {it!}
baz
<^P>
$ foo | bar | # ?Do? *the* $bar$ && [do] {it!}
bazWow I hate* that. I use bracket comments. They're cool cause they are bracket comments, so I use it in scripts to document pipelines. They are annoying cause they are bracket comments, in an interactive shell I have to type more and in TWO places. It's fun to reason-out how it works ;)
$ echo foo | tr fo FO | sed 's/FOO/BAR/'
BAR
$ echo foo | ${IFS# tr fo FO | } sed 's/FOO/BAR/'
foo
foo \
| bar ${IFS Do the bar. Do it. } \
| baz

Unlike how a bunch of projects end right as they start to get good, this has a great ending. Thank you

I completely understand! I'm also Polish American. I have to say it helps when mother's side of family is Gdańsk+west and father's Lublin+east. My wife's family is all from Warsaw area and I had to translate for my father-in-law during a holiday to Władysławowo-Hel (probably helps my aunt's father's side is Kashubian too, mmm... dessert first).
I was blown-away on holiday to Croatia. It was so unexpectedly relatively easily understandable after Czechia, Austria, and Slovenia. I was all, "What just happened!? Shouldn't this be something more like Italian?"
It took only a month for me to be able to communicate in Ukrainian with my ESL students, you're totally right about Cyrillic. And I too think in concepts but switch my brain to express them externally via language, whatever that language may be at the moment. I am terrible at translating OTOH, so unnatural!
But it has it's limits, I got to a point after German and Norwegian that I thought I harbored a super-power. Then I went to school in Hungary ;) I also had an ESL student from Lithuania, yep incomprehensible.

"To provide causal as opposed to correlational evidence, we take advantage of the fact that, in Wales, eligibility for the zoster vaccine was determined on the basis of an individual’s exact date of birth. Those born before 2 September 1933 were ineligible and remained ineligible for life, whereas those born on or after 2 September 1933 were eligible for at least 1 year to receive the vaccine."
