Drilling a hole at the crack tip does zero to stop it from spreading, the crack just keeps going past it half the time. Hairline like that on a hardy hole usually means the whole corner's about to go, so babying it now is just wasting time. Losing the corner bites, but that anvil's on borrowed time and you're better off planning for a replacement than trying to save it.

Paper lids are slept on, honestly. Had the same doubt when we switched for our pho cups because the plastic dome ones kept cracking in cold weather and leaking everywhere. The paper plus seal ring combo just doesn't budge, even stacked in a hot trunk for a couple hours. Only thing I'd watch is really oily broths, those can soften the rim a bit after like 45 minutes. For ramen you're fine.

Mine was "password123" for way too long and I did the exact same thing, sticky note and all. A guy at the gym actually told me my network name because his phone auto connected when he walked by my house. Felt like such an idiot. After that I set up a guest network with its own name and a password I change every few months. The guest network keeps people off my main one so they can't see my printer or my laptop or any of that. Best part is when someone asks for the WiFi I just hand them the guest password and don't have to worry. Takes two minutes in the router settings and it's worth it.
