Tried agentic coding via the #claude connector in #xcode - can't say I'm impressed 🙄 Would expect editing project files as the primary use-case for choosing a built-in xcode experience over just editing source files in another editor / agent harness.

That feeling when you accept defeat and trash your starved out #sourdough. Bittersweet as it also frees up mental space and eliminates the reminder of your carelessness, every time you open the fridge to see the corpse of what you once hoped would bring your family fresh bread on a weekly basis ...

> do you find that your user-event handling callbacks often need to *read* new data? I mean, depends on your data modeling paradigm, but when I was working on Realm we had an object model where you could create using a sync call. Pretty useful, especially when creating circular structures.

Example of creating two objects circularly referencing each other.

I had this neat little idea for a great open source contribution 💙

A time-bomb triggered on the 1st of April to override the forEach method on JavaScript arrays to call the callback on the next tick, instead of synchronously.

@elevenlabs.io just announced raising $500M at an $11B valuation to transform how people interact with technology 🎉 Valuation doubling since I signed my contract ... coincidence? I think not 🤔 This place has so much talent and so much potential and I'm really happy to be a part of the journey!

Captive thumbnail signaling the $11.000.000.000 valuation.

Very relatable! The maintainer of the #Hermes engine is looking forward to Node-API support landing: A major milestone on the journey of adding Node-API to #ReactNative 💙 Lots of kudos and energy goes out to the team at @microsoft.com and Vladimir Morozov in particular! github.com/facebook/her...

I already did mine - took literally 7 minutes. Best time ever spent, providing strong signals for the maintainers of frameworks and libraries in this awesome community of ours!

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. Thankfully all was discounted (presumably usage is within the free tier? 🤷)

A graph showing spending of GitHub Actions form a fork of the Expo mono-repository totaling ~ $130 in the current month.

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" 😬🤦

Kræn Hansen 🇩🇰 @kraenhansen.dk · 02/08/2025

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. Grab your ticket before the "late birds" and use this link ti.to/RUC/react-un... if you want to save a bit too.

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.

Kræn Hansen 🇩🇰 @kraenhansen.dk · 09/06/2025

I suspect the main attraction is the food cooked on the fire.. #pågen #gifflar and tortillas with cheese and sausages 🙂⛺🔥

Starting my journey towards #Berlin 🇩🇪 for @localfirstconf.com! I can't wait to meet all the friends I didn't know I had 🤗 #localfirst

Walking by foot to the bus, taking me to the train, taking me to the train, taking me to Berlin 😊

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. (In hindsight ... somewhat obvious 🙈)

Kræn Hansen 🇩🇰 @kraenhansen.dk · 07/02/2025

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 🙄

Kræn Hansen 🇩🇰 @kraenhansen.dk · 15/01/2025

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 😂

BTW, is this a Danish thing or international? I tried asking ChatGPT, but that escalated quickly, assuming my girls are involved in organized crime 😂 (to swear" and "a gang" is spelled the same, but pronounced differently in Danish)

ChatGPT explaining the word "bandekasse".

Kræn Hansen 🇩🇰 @kraenhansen.dk · 11/01/2025

My two 6yo girls made this "bandekasse" (🇩🇰 for "swear box") where you have to drop in coins everytime you say a swear word. Now they're conspiring to find ways of tricking their grandparents into swearing to hustle them for money. I've got to acknowledge their ingenuity 😂

I know I'm not the average #typescript user, however I've wanted to import DOM types without polluting the global namespace many times now. I finally took the time to put together this PR: github.com/microsoft/Ty... 🤞

Kræn Hansen 🇩🇰 @kraenhansen.dk · 05/01/2025

Making great progress on my intent to make Node C++ Addons available for React Native. The screenshots show the RNTesterUnitTests app calling into a "HelloAddon", first via the node-addon-api (C++ wrappers of the lower level C-API) and then via JSI.

Kræn Hansen 🇩🇰 @kraenhansen.dk · 17/12/2024

This is cool an' all - but ... I'd rather spend the extra 5 minutes writing out a user defined assertion function for this 😎 const message = parseIncomingMessage('{"type":"crud.create"}'); console.log(message.type); www.typescriptlang.org/play/?ssl=33...

Kræn Hansen 🇩🇰 @kraenhansen.dk · 16/12/2024

A new strong contestant for the "smallest PR to React Native" (this time I contributed 4 bytes) but hopefully impactful none the less 🙏 Bundling on iOS was broken for devs with whitespace in their `node` binary paths: github.com/facebook/rea...

Here are some of my thoughts, based on the experience.

First (and likely last) #gym picture: I've noticed how a treadmill run makes me prepare a mental list of tasks for the day 🏃‍♂️📒 I suspect it keeps my mind focussed on anything other than my physical body and its surroundings 😅 (i promise I won't turn into a full-on #gymbro from now on)
