Linux triage

You ssh to a random Linux system and are trying to figure out what is going on.

System identity & hardware

uname -a                  # kernel version + arch
cat /etc/os-release       # distro info
lscpu                     # CPU details
free -h                   # RAM usage

#!/usr/bin/env node

// 0 is even, 1 is odd, and N is even if N-2 is even

/*
Which one is easier to read and understand for you? (Subjectively)
Which one is significantly safer (aka, what could go wrong)? (Objectively)

I found 4 scenarios that would crash the less safe one where the safer one
will return "undefined". Did I miss any?

Ghostty config

Install

Just brew install ghostty. Launch it, then choose Ghostty -> Settings. Paste the text into the bottom of the config file and save.

Reload the entire app (using cmd + q), because some changes require it to restart and not just reload the config while running.

Note: This is assuming you've already got a good shell, powerline, and config manager like oh-my-zsh.
