Please don't get me wrong here 🙏
Let's just say I find it curious when four female devs (three of which have AI altered pics) and none have their workplace listed, starts following me the same day 😬

PSA: If you've cloned a repo like @expo.dev's mono-repo, remember to disable @github.com Actions.

Working on my @reactuniverseconf.com presentation I need inspiration for a stupid "native API" to implement a Node.js native addon for: "best" candidate is `ejectCupHolder` with me narrating "like this example of ejecting a compact disk drive".
Afraid people will be too young to get the "joke" 😬🤦

This config of the rule did the trick for me. Had to use "suite" and "test" here even though I'm importing `describe` and `it` 🫤

Okay 🥵 I'm not saying that this is my most beautiful creation this summer. I'm also not not saying that this took the most sweat and tears 😑 Thanks #feddelegrand for being the soundtrack of my suffering!

I'll be speaking at @reactuniverseconf.com September 2-4, 2025 in Wrocław, Poland 🥳 My talk will be centered around the #Node-API support for #ReactNative that I've recently helped build.

That's great to hear! I'm really excited that this is public now and we'll be able to collaborate more with the wider community.
I like your art BTW. I wonder if the Node-API for React Native logo spark any ideas from you: github.com/callstackinc...

It's been a surreal experience walking from my hotel to the @jsnation.gitnation.org venue this morning. This neighborhood is nuts 🤯 I'm genuinely wondering if this is part of the curated experience.

Favourite gym routine: Split screening in a @callstack.com stream with the "Strong" app. This enterprise framework gets me fired up 🔥💙 also @grabbou.com dropping Node-API mentions gives me that extra 💯🦾😆

I've since transitioned to something even more energetic 😊 This one for example - I imagine myself frantically running from the AI overlords, chasing me with machine guns strapped to a pack of Boston Dynamics spot robots 🏃♂️🤖🤖🤖

What's up with the usage of JavaScriptCore? Why is it not declining in usage, but instead increasing from 28% → 42% (+14pp)? Compared to Hermes increasing from 57% → 64% (+7pp).

I've added displaying what each resolution resolved "to".
Using 🔴 to show an unresolved module.

I've often dreaded debugging how / why #TypeScript was including a particular file into my project.
But no more, because I built myself a neat little CLI today:
npx resolution-explorer

I don't know how abstract this is 🤔 But here I'm drawing a smoking log from yesterday's firepit. It filled up the entire livingroom and it's constantly reminding me about the freezing dinner we had while exchanging the air inside 🙄

Also, this is all I see while listening to the groovy beat when downloading the native app for Android 🤔 Either something is broken or it has a very long loading scene 😂
