I have no experience of my own, but at least in my country, IKEA offers a 15 year warranty on their stainless steel cookware, except the ones with nonstick coating (which isn’t nearly as durable). It’s fairly affordable too. I’m thinking of replacing some nonstick pans of mine with their stainless steel offerings, but haven’t yet pulled the trigger.
I figured it might be interesting to add here because it’s one of the few companies that sells in most of the western world and I believe the lineup is similar everywhere. If anyone has experience with their cookware, I’d be happy to hear about it.
Exactly. A 10% decrease in run time for a method is a small optimization most of the time, but whether or not it’s premature depends on whether the optimization has other consequences. Maybe you lose functionality in some edge cases, or maybe it’s actually 10x slower in some edge case. Maybe what you thought was a bit faster, is actually slower in most cases. That’s why you measure when you’re optimizing.
Maybe you took 3 hours of profiling and made a loop 10% faster but you could have trivially rewritten it to run log n times instead of n times…
