Haven't pinned down exactly why, but when switching from the Mac to Windows, Windows feels snappier. While the Mac is a faster machine.

I'm a simple man. Writing code with Purple Disco Machine on the background is all it takes to make my day.

Look at me optimizing my workshop instead of building the thing. The whole dev space is addicted to productivity porn.

Interesting. Twitter is moving to Elixir.
JUST IN: 𝕏 announces it will soon roll out a 90% reduction in web app load times.

GitHub user from almost day one (#825), and I share Mitchell's frustration. Scale and slop are blamed, but it's the enshittification eating the whole web.
Ghostty is leaving GitHub. I'm GitHub user 1299, joined Feb 2008. I've visited GitHub almost every single day for over 18 years. It's never been a question for me where I'd put my projects: always GitHub. I'm super sad to say this, but its time to go. mitchellh.com/writing/ghostt…

Bullshit. Winning teams have the psychological safety required to win - not because they coddle each other, but because they trust each other to perform, and hold each other accountable. It takes a *very high* degree of psychological safety to do that. Don't forget the *actual definition* of psychological safety: the shared belief that the environment is safe enough to take personal risks. Everything about building winning teams is helping people get comfortable taking more risk - with the product, with their career, with their relationships to each other. What those teams aren't is easy to build, or zones of swaddled comfort where nobody does a bad job and everyone gets praised. High performance machines care about psychological safety *because* they care about winning. You have to build honest, real trust - not the kind that comes from telling folks what they want to hear, but the kind that comes from *telling the truth and doing what you say you will do*. Then being judged on the outcomes of your choices. I get that it's popular right now to say shit like this, but it's just bad advice. Even they don't actually believe it when you hear them talk about how people should behave.

AI makes bad architecture fail faster. Clean abstractions aren't optional. Without them, the mess compounds at machine speed.

The most powerful form of AI collaboration is not AI generating code but using AI for understanding code.

Things are moving so fast right now. I already read a lot during the week, but I still have a whole backlog of interesting articles that I work through during the weekend.

3rd rewrite of a new agentic system in 48 hours. Frustrating? Yeah, a little. But I'm learning so much. It's a relentless loop: spend hours on the design, execute fast, hit reality, learn, restart. Each pass I'm making fewer mistakes and building real intuition for how the system I'm building works best.

I created two skills which I always found to be gotcha's when working with #elixirlang and LiveView. Both can have a big impact on user experience. First, LiveView and optimistic updates, making sure that the UI stays responsive, even when there is latency. github.com/wunki/amplify/tre…

Second is working with forms, where you have to make sure that forms don't get wiped on reconnect, or when and how to use debounce to make sure you don't spam the backend. github.com/wunki/amplify/tre…

Let me know what you think and how we could improve them. PRs or comments are welcome. Let's share best practices so we can use LiveView and all its benefits without compromising on the user experience. #myelixirstatus
