#til — Public Fediverse posts

While I guessed it was the case, #TIL (or today I *confirmed*) that #awk doesn't support first-class functions, meaning you can't do

function x(s) { print "X:", s }
function y(s) { print "Y:", s }
BEGIN {
# can't assign a function to a variable
a[0] = x
a[1] = y

# which would allow me to randomly choose a function:
srand()
zero_or_one = int(rand()*2)
a[zero_or_one]("hello")
}

Wiatrakowiec (zwany również żyrokopterem) to statek powietrzny przypominający wyglądem niewielki śmigłowiec.
Unosi się dzięki wirnikowi nośnemu, który obraca się swobodnie pod wpływem przepływu powietrza podczas ruchu do przodu.Wirnik nie jest napędzany silnikiem podczas lotu – napędzane jest jedynie śmigło pchające (lub rzadziej ciągnące), które zapewnia prędkość postępową. Wiatrakowiec potrzebuje krótkiego rozbiegu, aby oderwać się od ziemi.

#TIL the rain in my eyes is less acidic than when I was child. Progress!

#TIL! #LuciVanOrg sang 1996 "Meine #Bildung hab' ich aus dem #Fernsehen", bei mir ist's #Wikipedia:

"Die Gestaltung von Rasengleisen ist … keineswegs ein neues Gestaltungselement der #Straßenbahnplanung. So wurde 1905 das erste #Rasengleis der Welt in der #Hardenbergstraße in #Berlin eingerichtet."

https://en.wikipedia.org/wiki/Green_track#cite_note-9

Auch die #Tram, die schönste Form der #EMobilität, stammt bekanntlich aus Berlin. Damals wurde sie einfach "Die #Elektrische" genannt.

Übermorgen, am 16. Mai jährt sich zum 145. mal die erst Fahrt in #Lichterfelde, damals noch Vorort Berlins, heute Teil des Bezirks #SteglitzZehlendorf.

#TIL (ok, yesterday ;) that rsync --delete only works if you're specifying a directory to copy, not individual files.

So

rsync -rvt --delete /path/to/dir user@server:

will work, while

rsync -rvt --delete /path/to/dir/*fileglob* user@server:

will not.

#PSA ;)

Solved the mystery of why there was a huge pile of empty pine cones below one linden tree when the snow melted.

I assumed squirrels or some other forest creature, but yesterday a friend suggested it was the woodpeckers work, who uses holes in the tree as cone holder and then pecks out the seeds.

So I looked up and indeed found two spots where cones were still stuck, one in a hole and one between trunk and a branch.

Clever birds. No hands but know how to utilize their environment :)

Fein fein. Die #Ansible Collection community.general.nmcli erwähnt erst beim ausführen, dass es bitte:

Failed to find required executable \"nmcli\" in paths:

In der Doku habe ich es nicht erwähnt gefunden.

Eigentlich wollte ich nur-mal-eben-schnell ein virtuelles Netzwerk-Interface anlegen.
Aber ein Shell-Command

wollte ich mir eigentlich(tm) sparen und das per Ansible-Modul machen. (1/2)
