From 25 years of development experience, I've found it is best not to estimate - at all. Estimation just wastes time.

This is very true:

"Estimation is ultimately a futile effort. Software, more or less, is like writing poetry. Or solving mathematical proofs. It takes as long as it takes, and it’s done when it’s done. Perfect, or imperfect, estimation won’t change how long it takes to complete the work. If that sounds horrible to you, then go do something else."

software: the warm feeling of recently washed and dried clothes * - * (one of my favorite feelings)

Yes! I've made a couple of contributions. My favourite is something I added in DEV's notification settings - "Send notifications when someone reacts to my comments or posts".

There are a number of things here you can do without extensions just by using the developer tools.

Timeshift => just go to the sensorstab in the dev tools and select your desired location from the location dropdown. Need to debug a specific location? Just click the manage button next to the dropdown and add your own.

Pesticide => Dead simple; just add a new style rule in the elements tab. * { outline: 1px solid red; }. Doing it this way has the advantage of not being tied to any browser. It'll work in anything, even ancient versions of IE.

...half asleep, I click onto DEV, see Using Children in React, and forgot all my programming knowledge briefly. So I saw literal children being called over for a work project.

Sips coffee, glad to leave the website building to Ali Spittel and other brilliant minds.
