> There's an expression on Wall Street, often attributed to Warren Buffett, which goes, "They don't ring a bell at the top." There's tremendous wisdom in that adage, because while in retrospect it's easy to pinpoint the day that the market (or even a specific stock) reached an all-time high that looks unlikely to ever be attained again in the foreseeable future, at the moment it happened it was impossible to recognize. That's because, unlike market bottoms, which usually have a crescendo feeling to them accompanied by investor panic, a market top generally passes without fanfare, indistinguishable from the series of tops that preceded it.

> You know when else they don't ring a bell? For parents, they don't ring a bell the last time you read Goodnight Moon. They don't do it the last time you watch Sleeping Beauty and they don't do it the last time you help your daughter put on the same article of clothing she's wanted to wear every day as a toddler. Instead, a couple years after the fact, you find the book on a shelf, the DVD in a box, and the tights with the pink ballerinas on them in the back of a drawer. You can't for the life of you remember the last time you read the book, danced to "Once Upon a Dream" with your daughter on your feet, or helped put those tights on. But you do know that now she reads to herself at bedtime, she dances, alone, to Taylor Swift, and the tights—well, the tights wouldn't even make it over her knees.

You get it. It’s about value. Keep you eye on that north star and you won’t go wrong.

Whose value? How do I value? Can I reconcile disparite value? Yep, those are the right questions.

For me, I read this and want to give a shout out to Zen and the Art of Motorcycle Maintenance, but that’s just me.

I enjoyed the read, thank you.

Prepared statements work fine. Views can be tricky.

The statistical invalidation will in general disable caching on views since their results will change without any corresponding writes (because we only associate writes with the backing tables of the view). Currently our best answer to views is the new stale-while-revalidate flow which revalidates against the db while still serving a hit. With this feature enabled, one can turn off invalidation (if the resulting eventual consistency is acceptable).

More details about how invalidation works here:

Not out of vanity (ok, a little) but because I think the idea has importance that has not been fully explored. The article's Bayesian perspective may be the whole story but somehow I don't think so. Unlike the article's author, my work left me feeling model architecture was the most important thing (behind training data) whereas they seem to feel it is ancillary.
