What are they and why should I use them?
When I first started using Redux, I didn’t understand selectors. They seemed like a completely unnecessary intermediate layer that just slowed me down. I learned later, however, that they’re actually there to speed me up.

Everyone can use a little help, sometimes...
It isn’t always easy to know when to use Rails view helpers. You don’t want to sit down and try to write a bunch of helpers before you have a UI spec, or even before you’ve started to write a rough layout of your markup. But at some point, hopefully earlier in the implementation phase, it’s good to remember that helpers are there to help.

Good design starts small
Software development is an iceberg and if you skip the stuff beneath the surface, it’ll just sink you later. Give me three minutes and I’ll save you enough time to break even on a ten-minute task.

#update_column used to be a critical performance tool before Rails had dirty
attribute tracking. Now that ActiveRecord manages dirty tracking for us, there
are very few legitimate uses of this function with a lot of serious down-sides.
