## learning how to set pkg_config_path

icu4c is keg-only, which means it was not symlinked into /usr/local,
because macOS provides libicucore.dylib (but nothing else).

If you need to have icu4c first in your PATH run:
  echo 'set -g fish_user_paths "/usr/local/opt/icu4c/bin" $fish_user_paths' >> ~/.config/fish/config.fish
  echo 'set -g fish_user_paths "/usr/local/opt/icu4c/sbin" $fish_user_paths' >> ~/.config/fish/config.fish

For compilers to find icu4c you may need to set:

# The following functions append/prepend the specified directory to the path variable specified by name
# If the directory is already in the path, it is first removed and then appended/prepended.
# Examples:
#
# Prepend `~/bin` to `$PATH`:
#   prepend_path PATH ~/bin
#
# Append `~bin` to `$PATH` instead:
#  append_path PATH ~/bin
# (this will remove `~/bin` from the beginning of `$PATH` first)

Raspberry Pi on Internet via reverse SSH tunnel

HackerNews discussed this with many alternative solutions: https://news.ycombinator.com/item?id=24893615

I already have my own domain name: mydomain.com. I wanted to be able to run some webapps on my Raspberry Pi 4B running perpetually at home in headless mode (just needs 5W power and wireless internet). I wanted to be able to access these apps from public Internet. Dynamic DNS wasn't an option because my ISP blocks all incoming traffic. ngrok would work but the free plan is too restrictive.

I bought a cheap 2GB RAM, 20GB disk VM + a 25GB volume on Hetzner for about 4 EUR/month. Hetzner gave me a static IP for it. I haven't purchased a floating IP yet.
