A reader asked "Why should you help others play their cards? everyone seems so focused on their own"

moral philosophy is hard, altruism especially

here's 4 reasons I help others play their cards
1 – it's the right thing to do. Others helped me play my cards so I help others play theirs
2 – The optimal solution to the prisoner's dilemma is tit-for-tat

Play nice at first, then do whatever the other person did last. Avoid playing with people who aren't nice, but let them know you're down to change.

True both mathematically and experimentally.
3 – You never know when creating good-will is going to have positive effects

The person you helped 10 years ago could be key to doing the thing you wanna do today.
4 – It's better to grow the pie than to squabble over a pie that's getting smaller.

Everyone wins.
People who aren't charitable to others are playing from a position of fear and low confidence.

Not a strategy you wanna emulate 😉

I interviewed 17 senior engineers in 18 weeks – 7 just in April.

What do you wanna know? ama
#seniormindset
Most folks who thought they were senior evaluated at mid-level.

You’d trust them to write good code, but not to design solutions and component interfaces from scratch.

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 ...
Hey we did this thing and it isn’t instantly showing up!!

Yeah it wouldn’t. Wasn’t designed to.

BUT WE NEED IT!!!!!111one

💩

Okay, we’ll clear the cache for ya. Ping us when you need us

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
I think most people would say Turkey is white.

Okay what about Syria? It's parallel to Cyprus on the map. Is Cyprus white?

What about North Africa in general. Especially Algiers, Tunis, Morocco, etc. White or brown? 🤨

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 🧵

swizec.com/blog/variants-…
You start with a smol reusable component

Then it grows, you boolean all the things ImageImage
And your component blows up in complexity. At 3 bools you have 8 different ways to hold your component.

You think you'll get it right every time? Debugging becomes into a game of whack-a-mole Image

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.

Worst part of working with Firebase is Google's SEO.

Paste error into Google, get the docs. Docs don't even mention the error. 🙊

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.
2) Managing up with a great manager feels like Just Communication.

They set direction and talk company priorities.
You decide how to achieve those priorities, communicate blockers and hiccups, proactively say what's up, and keep the manager informed.
