YouTube and Twitter are full of “things developers should never do”. There's an endless demand for simple advice that applies in all situations. And that's not a bad thing. If there's a simple solution that works 80% of the time, this is valuable information. More practical than just "it depends." But advice-givers and advice-getters can do better. The best advice doesn't just solve an immediate problem. It tells you when to ignore this advice, and what to do if the problem isn't solved. I share a very old story about when I needed help sizing a connection pool, the advice I got, and the advice I now wish someone had given me. P.S Sorry about the audio quality. I had to record outside, and my lav mic wasn't as good as my desk mic.
