Actually, that's a thermal camera, not just a thermometer. The little gun-shaped ones are thermometers, they just give you a number. The cameras show you the actual heat picture, which is way more useful for finding drafts. The cheap ones are surprisingly decent now. I used a no-name brand one to spot a missing insulation patch in my attic last year.

Honestly, I'd just run a linter on save. It'll flag the semicolons and you'll unlearn it fast.

That whole "learn to expect it" line sounds like giving up. If your food keeps making a mess, maybe you're just doing it wrong.
