Your job as an engineer is to make yourself unnecessary.

A fun story 👇 We built a caching system for a slow 3rd party that our ops team uses to do stuff. Sometimes webhooks take 30min to tell us the cache needs updating.

Eh whatever, they set up well in advance. This isn’t a problem

And then ...

When Americans don’t understand how Europians can have such strong feelings about ethnicity when “everyone looks the same”

lol amateurs Racism in Europe is such a tricky topic *because* it's hard to draw a line.

Are Spanish people brown? Of course not
They became brown by creating Mexico ... waitaminute 🤔

Greeks are white yes?
Are Turks white?
Gets tricky because of the christian-muslim divide

Variants – a quick tip for better React components

A pattern I've seen lots is adding a bunch of booleans to cover different use-cases of a reusable #React component. This makes components hard to use

A variant prop has worked great so far 🧵

Then it grows, you boolean all the things ImageImage

Got so close to working Firebase support in useAuth last night I can almost smell it 🤞

here's a recap 🧵

swizec.com/blog/codewiths… We finished the stream with a broken flow. A callback doesn't callback, very strange.

And we found that Firebase is "hot garbage" as @tannerlinsley called it. Confusing API, strange docs, odd types.

Been having an interesting debate about "managing up" with some friends this morning and interesting patterns cropped up

👇 1) Managing up with a bad manager feels like you're doing their job. You aren't, but it feels like you are.

This is when folks are most frustrated and complain. It sucks for everyone involved.

Manager thinks you're unmanageable. You think manager just gets in the way.

Some fun stats from product sidehustle land 👇

Since March 2015

2695 hours
1.8 hrs/day average

3-ish products
~2800 sales
$139,208 revenue post fees
$81,767 expenses

$21/hour 🤔

This must be why most people share only the revenue numbers #open Now the obvious question: Why would anyone do this?

Well for starters it's still better than a coding job back home. My first job building websites was for $7/hour.

That was in high school.

LEARN WHILE YOU POOP: Why you should learn React 🧐

Hi 👋 I’m trying something new and need your feedback. What do you think of this as a format for a daily 2min video?

No pressure learning at 2 minutes per day.Start with WHY React all the way to a React 16.3 master in a month. LEARN WHILE YOU POOP: Why are components so great 🤔

React, Vue, Angular, or whatever. Components are the future and you should learn how to think in them. Here's why 👇

Hint: it's a lot like LEGO except you also have a 3D printer to make your own.
