Switch Bluetooth off when you're not using it. It quietly looks for things to pair with all day, and there's no reason to leave that open in your pocket.

You don't need fancy security software on your laptop. The encryption built into your Mac or Windows is the same kind banks lean on, and it's already free. Just flip it on and save the key.

Open your project: is there a lock file, is it committed, and does CI install from it instead of resolving fresh? Three yeses means your builds are repeatable. Fix any no.

"Close enough is fine for my business details." Not to AI. "Joe's Cafe" and "Joe's Coffee LLC" can read as two places. Pick one name and use it everywhere.

Tired of pasting the same key into three files? A single .env file holds it once, your code grabs it from there. Change it in one spot and you're done.
