I wrote a ZSH oneliner that generates a drop-in configuration for user@.service for setting the XDG base directory environment variables.
#!/usr/bin/zsh -f
print -- "Setting XDG_DATA_HOME to \"foo bar\" for demonstration purposes"
XDG_DATA_HOME="foo bar"
print -l -- "Base expansion" \
"\$(typeset -m 'XDG_*_HOME')" "" \
$(typeset -m 'XDG_*_HOME') ""
print -l -- "Add newline splitting and sorting flags: (fo)" \
"\${(fo)\"\$(typeset -m 'XDG_*_HOME')\"}" "" \

Maybe you're a Windows user, or someone working on the same repository as you is, or you do development across operating systems, or you're working with tools that break operating system convention, or...

Weird Coding - FizzBuzz in Befunge

Weird Coding - FizzBuzz in Befunge

Jan 28 2021

I seem to have a real infatuation with unconvential programming challenges. Whenever I get to do something completely new that is at the same time simple enough to take no more than a day or two, but also far enough 'out there' that just looking up the solution is out of the question, my brain really seems to light up.
