Made this silly lil' thing: xitter.cf/VaguelyRightHQ/status/…

I get done in one morning what used to take me over a week yet I'm still stressed and feel behind. Incredible.

15/ My frustration with this is that I think it will leave readers with the impression that a central idea in interp rested on a mistake and has now been overturned. I don't think the evidence presented supports that even if some of the findings turn out to be valuable.
Still only partway through, but this is a fascinating read
interpretability might be the most important scientific problem in the world right now, as I don't think we can solve alignment if we don't know what we're building. I think I have good news about it. I co-authored early work in mechanistic interpretability at OpenAI and came away pessimistic, because neural networks appeared to fold into arbitrary tangled knots. years later, I started openai's first large-scale automated interpretability project, finding about 2% of neurons legible with the primitive tools we had
with modern agentic tools and a much closer look, the picture looks totally different. the vast majority in models up to trillions of parameters are legible, and their circuits beautiful. many famous examples of tangled neurons turned out to be misunderstood. The roadblocks I expected mostly aren't there. I now think ambitious interpretability will be solved by the time we need it most, and possibly quite soon, as automated scientists keep improving. it may be a bitter lesson for interpretability: the simple thing, at absurd scale, works

My score today wasn't great, just 10/20.

DINOv2 has never seen a caption, and Qwen3 has never seen an image. We still aligned their embedding spaces without a single image-caption pair.
It even works when the images and the captions come from different datasets.

My consulting company just bought all the Claybook tech from Second Order Ltd bankruptcy estate for 10k€. I wrote it 8 years ago, now it's mine!
I spent half a year optimizing all the SDF ray-tracer inner loops and GPGPU simulators. GPT6 Astra Ultra gets nowhere close.
界隈では有名なInk & Switchが「特殊化され過ぎたツール」をアボカドスライサーで喩えているの、奇しくも自分も同じ課題意識を(ずいぶん低い精度で)白髪ねぎカッターになぞらえていて、みんな同じ気持ちを共有してるんだなぁって嬉しくなった

Reflecting on Illich's recent centenary: he wanted "tools for conviviality" which prioritized individual/local autonomy and situated improvisation over centrally controlled technology which could only be modified by professional elites.
In computing, that's often interpreted as a quest to spread liberatory understanding: everyone should be able to create and mold software; and/or programming should be made accessible to all. End the dependence on centrally-produced commercial software, etc.
It's ironic (and troubling?) that with AI, that long-sought individual autonomy might be achieved without any of the understanding or expertise, and in fact by making the black box much bigger and blacker.

On the SwiftUI team we had a joke: "all bugs are bridging bugs."
It's hard to build a declarative layer over UIKit! There's a lot of undefined behavior, especially in the subtle timing of the update cycle. And it's always changing.
Even sitting in the same hallway, with an explicit goal of keeping the two frameworks in sync, we couldn't do a perfect job.
I can only imagine how hard it's been for the React Native team.
Shop is the first of our apps to complete the move back to native. The team rebuilt it in Swift and Kotlin in just 12 weeks.
It now launches 23% faster on iOS and 50% faster on Android, with a 10x lower crash rate and a 109 MB smaller Android build. We expect those numbers to keep improving.

there was an iOS dev blog post from a while ago that was like “So you bumped your min OS target, here’s what you can now use” — does anyone recall this or have a link to it? Am I misremembering it?

after reading the spec, this actually solves nothing. and the rest of us not in the blessed in-group now has to feal with another mess.
just like with the skills "standard", which to date nobody has implemented properly, because for that you basically have to reverse Claude Code's slop.
we should stop calling our shit engineering.
