EmDash isn't the only project at Cloudflare to graduate from "is this a joke" to 1.0 today. Vinext started as the original slop-fork and is now running literally millions of Next.js sites. Turns out that all it took to make Next.js good was to reimplement the entire framework on top of Vite.

This is what I've been working on since January. I'm really pleased with what we've built, but most of all I'm proud of the open source community that we've built around it. It grew quicker than I could ever have imagined, and there's no way we could've shipped such a good product without them

This is an interesting post, and worth reading. I particularly like the aspects of code review that he identifies as not easily reduced to agent automatable functions www.adaptivecapacitylabs.com/2026/08/24/t...

There is more to code review than (automatable) detection

I have discovered a problem with my "AI now is like the internet in 1997" analogy which is that half you fuckers weren't even born in 1997 and so have no idea what I'm talking about.

I'm going to be launching something pretty big next week, which just happens to include a new atproto AppView, labeler, blob proxy, lexicons. It will have tens of thousands of users, most of whom won't even know they're using atproto, or have even heard of it.

I wanted to use my Steam Controller with my Switch 2, but it’s not compatible 😢 Luckily there’s github.com/jfedor2/hid-... I bought the adafruit board, dragged a file onto it to flash, hooked it up to the switch, and… everything seems to just work?? A++ would do again

It seemed like the new Sol / Luna models + price drop were a slam dunk yesterday over Anthropic, but it looks like the Opus 5.5 model is really surprising people? I'm not sure how much of that is "It's really good at making animations now" vs actually useful though

At least for the way I work with code today, models seem pretty saturated. Cheaper / faster please. And cloud environments. I need this agent stuff off my laptop.

I have a degree in Applied Math and would have jokingly said this in college because the course was basically “Oops, all matrices” It means something rather different today

You can see your correlated logs in the trace waterfall now and also they cluster instead of overlapping which is nice

Damn, Camille does not mince words 🔥
Finally, we come to people. This one is just depressing. Has AI made anything easier about the people management/people skills era? If it has, it has been swamped by all of the new interpersonal challenges we’re hitting thanks to AI.

To start, there’s the increased expectations. Many companies think that that increased visibility and waves hands AI productivity means managers can start to manage far larger teams, with no help coming as we reduce managers and don’t hire new ones. And of course, some companies are also expecting managers to write code because that is apparently the only individual contribution that matters (the idea that managers don’t make valuable individual contributions to companies is so mind-boggling I could write a whole additional piece on it). And while you’re doing this, you have to manage the AI transition: make sure your team is using AI enough, not too much, and soothe their anxiety, and deal with their impatience, and you too have to use it but no one is bothering to teach you how to use it well or soothe your anxiety, you are just expected to figure it the f* out.

So is it any wonder 1 in 3 managers are considering going back to individual contribution roles? Hell, if you’re going to ask me to write code and manage a huge team of people, I might just prefer to say, thanks, writing code is enough for me so I’ll go back to doing that.

I finally got around to finishing Act 2 in Silksong, and… I may call it there. My first experiences in Act 3 were just pure pain Like Team Cherry just went “We don’t have to make sure the casuals can make it through any more? Say no more fam”

anecdotally i'm finally starting to see things actually ship in the past year that aren't just "use the AI to build more AI harness" and it's roughly these categories in order: 1. software made by single programmers with a cohesive vision, that would've previously taken a mid-size startup

So… like… are all the Metroid games in the same timeline? The same Samus? Samus starts exploring an ancient alike civilization on an abandoned planet… again. And loses all her suite’s abilities… again. You’d think after the first dozen times she would have some mitigation plans in place?
