Is AI able to write code? I think we can stop asking this question: yes, it can!
Actually, it is way too good at writing (a lot of) code. In a surprising number of cases, when I ask an AI to write a moderately complex piece of code, it will produce an output that works.

I’m in both screenshots. I wonder if there should be two types of commits:
1. Quicksave: part of what I’m trying to achieve works, I want to be able to safely go back there and diff new changes against this state.
2. End-of-Level Save: I’ve finished a piece of work that is fully usable.

I find it frustrating that a lot of AI critiques out there are completely off the rails, claiming that AI does not provide any value at all and hallucinates 99% of the time.
The only thing this achieves is to discredit any legitimate critique.

Is it worth automating things?
I'm a software developer. My job is to automate things. Automation, over the last couple of hundred years, has made many of us rich (compared to our ancestors). So the answer should be simple, and yet it isn't... markus.oberlehner.net/blog/what-we...

What We Do - Markus Oberlehner
As AI threatens to automate jobs, this article poses the question whether automation is even worth it, whether it makes us happy, and whether happiness is even a worthy goal.

The pattern I see when I read from people I respect, who describe how they make AI coding work for them, is treating AI more like a natural language input modality:
Tell it exactly what you want and it will be able to understand and do it for you.

people saying ai is a fad don't know what they're talking about. i'm definitely not giving up my claude now; the ability to do structural refactors "change this thing to be layered like this thing in this other project" is fantastic. i *do* want the model to be local and hope we'll get there in time

I have a hard time getting excited about a future of even more centralisation where all of us (developers) are merely building widgets for OpenAI.
And probably having to pay a hefty 40% tax. Yay!

OpenAI just dropped the Apps SDK, built on MCP. This is the future of how users will interact with your apps.
You won’t need to build a chatbot anymore.
OpenAI is the chatbot.
You just expose your tools through MCP.
Exciting progress toward Jarvis! youtu.be/9e581mYtrrs

Typing this on my MacBook, I think about this picture at least once a day. It has completely changed how I see my Apple devices, from loving how tightly integrated everything is to feeling like a prisoner of the Apple ecosystem. Not a single day passes without me making plans for my escape.

So @nuxt.com gets stable chunks! Seems like a small improvement, but it is huge!
Big JS bundle sizes don't matter because they're downloaded once and then cached. Right? Wrong!
Up until now, caching has barely done anything if we were deploying daily.
Stable chunks fix that! youtu.be/eryRM-ovpyY

I get that as a tech CEO, you sometimes have to play the game, and you need a healthy dose of pragmatism.
But how those tech CEOs can look themselves in the mirror kowtowing to this US president is beyond me.
I find it frightening. Is there anything they won't do for financial gain?

Controversial take: AI is merely a new I/O modality.
In the past, we had structured text, graphical UIs, and "structured" voice (already AI-driven); now, with LLMs, we also have unstructured text (and voice).
The unstructured text I/O modality allows us to do some impressive things, no question.

Recently I told my fiancé about my angst that I’m just not good at AI coding because I’m just not getting the results other on social media claim to get. She offered a great insight:
“Maybe you’re expecting more from it than others?”
I think that hits the nail on the head!

Enlightening perspective on the current state of LLM discussions.
the gamble is that you won't ever have to learn or understand what you're doing — so you don't need to start now. each day you don't learn stuff you have to double down on that bet because you're losing time. and peer pressure reinforces it

- Vibe coding is fun, until it isn’t (and somewhat addictive)
