1. brew edit node@18
2. Insert ENV["CXXFLAGS"] = "-Wno-enum-constexpr-conversion" after ENV["PYTHON"] = ...
3. brew install node@18
4. Profit!

Notes:

• i. Don't bother reporting this to homebrew because it has severely unprofessional contributors.
• ii. Clang/LLVM people insist on breaking all software and systems for idealological purity.
• iii. Node people refuse to take ownership of this.

Auto Ethernet/Wi-Fi switching script for macOS

! CRITICAL PROBLEM ! Currently broken because ...../airport -z no longer functions and the replacement is uncertain and nonexistent for now

Installation

1. Add local.auto-switch-wifi-ethernet.zsh to /usr/local/sbin
2. Add local.auto-switch-wifi-ethernet.plist to /Library/LaunchDaemons
3. Create /usr/local/.home.wifi.ssid containing the Wi-Fi network name (SSID) to try to connect to when Ethernet is no longer internet reachable
4. Start it permanently sudo launchctl unload -w /Library/LaunchDaemons/local.auto-switch-wifi-ethernet.plist

0. brew install ncurses ruby

1. gem install curses -- --use-system-libraries --with-ncurses-dir="$(brew --prefix ncurses)" --with-cflags='-Wno-error=incompatible-pointer-types'

This is because the Ruby maintainers are hipsters unable to work effectively with reality and Clang/LLVM breaking everyone's shit.

// Specialize stack to work with forward_list (STL singly-linked lists)

// Notes:
// - This is a proof-of-concept as an exercise for template specialization. Don't use in production!
// - Not cache-efficient.
// - Use stack<T, vector<T>> most of the time instead.
