My bouldering is weak, my chess game is poor, my Neapolitan pizza is terrible but my JS code is worse. 🚀 marcoss.hashnode.dev

No matter how many instructions or skills I give Claude, it cannot seem to figure out how to test what matters, and instead constantly tests implementation details. It's almost like it was trained on a bunch of data with tests that checked unimportant implementation details.

the focus on whether you read the code or not is the wrong thing to look at if you have software you're responsible for, you should be able to answer questions from memory about how it works the expectations for how well you can do this should not be any different now

I'm announcing Byte Binding—a modern, accessible, and powerful EPUB editor. This is for every author who's tired of errors when uploading their books to storefronts. For every creative soul who wishes their editor could do more. Because your digital books deserve better.

My experience with agents is that it doesn't make my work "faster". In the end it costs roughly the same amount of time, if not longer But my role has shifted from "builder" to "sculptor", which is a completely different job. I hated it at the very beginning tbh, but I'm getting better at it slowly

New demo: Animated CSS Grid Layout. codepen.io/bramus/pen/o... Here’s the thing: No View Transitions. No JS at all. Instead, it uses Anchor Positioning to anchor the cell contents to the cell. Then, CSS transitions are used to animate the contents to their new location as the grid re-layouts.

UX = user experience DX = developer experience EX = executive experience guess which one is most responsible for the growth in AI usage?
