To symlink SSH_AUTH_SOCK on boot to system-wide switch the value from default ssh agent:

1. Change /opt/homebrew/ to the correct homebrew path (/opt/homebrew is for Apple Silicon and /usr/local for x86)
2. Change the ssh agent as needed, this example uses https://github.com/FiloSottile/yubikey-agent
3. Save as ~/Library/LaunchAgents/link-ssh-auth-sock.plist
4. Run launchctl load -F ~/Library/LaunchAgents/link-ssh-auth-sock.plist

Falsehoods programmers believe about time

This is a compiled list of falsehoods programmers tend to believe about working with time.

Don't re-invent a date time library yourself. If you think you understand everything about time, you're probably doing it wrong.

Falsehoods

• There are always 24 hours in a day.
• February is always 28 days long.
• Any 24-hour period will always begin and end in the same day (or week, or month).
