If you have an Apple developer account or an app in the App Store, read this now and share it. Apple rejects your app. The notice is vague, so you fix what you reasonably think is wrong and resubmit. Apple approves it. Months later, with nothing in review, Apple terminates your account under 3.2(f) for “a pattern of manipulative or misleading behavior.” Every app gone. No explanation of what you did. Your crime? Trusting the approval. Apple’s own reviewer looked at your fix, with your rejection history in front of them, and said yes. Then Apple turned that yes into evidence against you. So who’s misleading whom? I ran App Review for seven years and wrote the guidelines. 3.2(f) used to mean real fraud. Now it’s being used against developers who did exactly what Apple approved. I’ve made this Substack post free for everyone. Every developer needs to see it before this happens to them. Share it before someone you know gets that email. phillipshoemaker.substack.co…

Looks great but the constant, almost metronomic, cuts prevent any immersion and make it seem amateurish. Would love to see clip length properly extended in next few years. It’s a surprisingly strong blocker for good story telling.
Watch Episode 1 of our Odyssey series made with Grok Imagine. Let us know in the comments if you'd like a full breakdown of how it was done! Creative collaboration with @WonderStudiosX and director Dev Walker @glumlot_

Maybe one day FSD will be so prevalent that inferior competitors and humans will have better safety records because their errors are ‘patched’ by the FSD fleet.
From yesterday's earnings call: “It’s easy to get to the first 90% and make a cool-looking demo. But when you get into the long tail of this problem, it’s so long that people don’t realize anyone with their sane mind should not attempt to solve this problem. It’s so difficult and so long-tailed, and especially to get to a safety point where you can drive safely for millions of miles with no injuries and so on. That’s going to be extremely hard. As we release unsupervised FSD to the broader customer fleet, I don’t think anyone can match it in several years.”

People are AI hacking TV’s shitty software and it’s awesome.
This is how fast the TV moves now that Claude deleted all the BS laggy bloatware it comes with

We built a car to bring you the time and weather... Seriously, though, the design is a great mashup of so many other devices
Apple’s pretty damn great at dashboard design now.

"The culture on X today is remarkably friendly and inclusive. It is a cheerful place", I couldn't agree with @daringfireball more. X is the place to be if you genuinely like technology and progress. Just such a delightful optimism here. daringfireball.net/2026/10/x…

Thrilled to welcome @spacexai as a Founding Corporate Patron for the Omacom Foundation. That's $1,500,000 in @grok tokens for the maintenance and development of Omarchy. Maybe soon they'll be beamed straight from orbit? Let's go 🚀🌕 omarchy.org/news/2026/10/spa…

I'm not super up to date with the latest slang and terminology folks are using these days, but I believe these are called "schools"
We created gyms because modern day work no longer required physical activity. Without exercise, our muscles atrophy. I predict we’ll need gyms for our brains too, once AI starts doing our knowledge work.

I used GPT-6 Astra to break an unsolved cipher to one of Napoleon's generals that had gone unread for 217 years. What makes this impressive isn't actually the codebreaking, but that Astra completed the entire multi-modal workflow in ~6 hours from a single image and goal. 1/6🧵

We are entering the age of opportunistic software. There’s so little downside to spinning up a random idea. It’s really amazing but I wonder just how useful it really is. LLMS still seem to be missing asking the *why*. They just do.
Opus 5.5 built me the most impressive web app I've seen yet. I asked for a visualizer of my MLX processes. I said "call it PonteMLX", from the Latin "pontem", or bridge. Give it a classic, antique look. This is what it made. The river flows in real-time as tokens are processed locally, it monitors different MLX API gateways, and it updates RAM usage. For the assets? It found Qwen-Image-2.1 locally and coordinated it to create images for the app. I did not prompt that. Claude is still unmatched at frontend, and Opus 5.5 feels GREAT to use so far.

One of the key points about Space Xs data centre idea is that it is cheaper. Access to land is not the issue. It’s power and accessibility. There’s lots of room in the middle of nowhere in the US but it’s not usable because of the above.

All of this of course relies a lot of things to go right, but satellite comms used to be small numbers of huge sats in geo stationary orbit. Now’s it’s lots in very low orbit. SpaceX data centers are kind of a low cost disruption.

I’m not sure many people realize what an incredibly difficult thing Tesla has accomplished with FSD. This post doesn’t even mention owning massive specialized data centers built from the same chips as in the car.
현대자동차그룹의 엔지니어 여러분께. 안녕하세요. 아쇽입니다. 자율주행 출시를 전략적으로 늦추셨다는 소식을 들었습니다. 충분히 이해합니다. 저희도 이 문제가 얼마나 어려운지 알고 있습니다. 동료 엔지니어로서 몇 가지 응원의 말씀을 드리고 싶습니다. 먼저, 데이터 수집을 위한 하드웨어를 수백만 대에 장착하는 일이 잘 진행되기를 바랍니다. 카메라와 컴퓨팅 장치뿐 아니라 저장공간, 통신, 전력, 냉각까지 필요하겠지요. 연구개발팀이 필요한 사양을 모두 적고 나면, 구매팀에서 연락이 올 겁니다. 그 비용을 차값에 반영하면 고객에게 설명해야 하고, 반영하지 않으면 재무팀에 설명해야 합니다. 어느 쪽이든 응원합니다. 엔비디아와의 협상도 잘되기를 바랍니다. 칩 가격도 중요하겠지만, 소프트웨어 비용과 데이터 사용 권한, 향후 변경의 자유도까지 좋은 조건을 확보하시길 바랍니다. 여러분의 장기 목표와 공급사의 장기 수익성이 아름답게 일치하기를 기원합니다. 아참. 데이터를 많이 모으신 다음에도 할 일이 조금 남아 있습니다. 어떤 장면이 필요한지 찾아야 하고, 왜 실패했는지 알아내야 하며, 그 장면을 어떻게 학습시킬지 결정해야 합니다. 비슷한 도로 영상이 백만 시간 더 생겼는데 어려운 좌회전은 그대로일 수도 있습니다. 저장공간은 늘었는데 실력은 그대로인 상황을 만나지 않으시길 바랍니다. 물론 학습이 잘되면 검증이 기다리고 있습니다. 어제 못하던 좌회전을 고쳤는데, 어제 잘하던 횡단보도 대응이 나빠지지는 않았는지 확인해야 합니다. 새로 맞힌 문제를 세는 일보다, 새로 틀리게 된 문제를 찾아내는 일이 더 오래 걸릴 수 있습니다. 여기서부터는 응원을 조금 더 보내드립니다. 그다음에는 이 모든 과정을 빠르게 반복해야 합니다. 수집하고, 선별하고, 학습하고, 검증하고, 차량에 맞게 최적화하고, 다시 검증하는 일입니다. 큰 서버에서 잘하던 모델이 차량의 메모리와 전력 한도 안에서도 같은 판단을 제때 내리는지 확인해야겠지요. 모델을 가볍게 만들었더니 판단까지 가벼워지지 않기를 바랍니다. 차종도 가능하면 단순한 편이 도움이 될 겁니다. 정확히는 차종 이름보다 센서 배치, 컴퓨팅 장치, 차량 제어 특성의 조합이 중요하겠지요. 브랜드와 차종이 다양하다는 것은 영업팀에는 좋은 소식입니다. 검증팀에는 확인할 조합이 늘었다는 소식일 수 있습니다. 표준화가 잘되기를 바랍니다. 검증팀의 주말도 함께 응원합니다. 그리고 5년 뒤에는 꼭 테슬라를 망하게 해주시길 바랍니다. 경쟁은 좋은 일입니다. 엔지니어에게도 분명한 목표는 도움이 됩니다. 다만 한 가지 양해를 부탁드립니다. 그때까지 저희도 개발을 계속해도 괜찮겠지요. 저희는 아직 일정을 전략적으로 늦추지 않아서요. — 가상의 아쇽 드림

Ryan makes a great point here. What’s interesting is that with a quick check of the accelerometer data to determine orientation prior to opening, you could move the blur to the center which would still make for a good experience.
THIS is how everyday users will open the Duo, not the controlled way Apple showed, so the incredible fade illusion is likely to be annoying. 🤷‍♂️

This a fascinating bit of investigation.
This post looks like the start of a VERY sophisticated and well-funded PR operation to get support for Democrats to regulate AI into oblivion. Let me show you how it works: 1.) This guy, with minimal followers and no previous account activity, goes to the Wall Street Journal which publishes an exclusive with quotes from him on his resignation 18 minutes BEFORE this post goes up. Planning was clearly done in advance. 2.) Within hours, it has tens of thousands of reposts and the account has 100k+ followers. The post is punchy, quotable, it almost seems professionally written. The first three accounts to quote tweet it all do so within 15 minutes of the initial posting. Remember, this account had basically zero engagement beforehand, so an organic reach explanation seems unlikely. According to Grok those accounts are @_NathanCalvin (General Counsel at Encode AI), @peterwildeford (Head of Policy at the AI Policy Network), and @DKokotajlo (Head of the AI Futures Project), all of which are up-and-coming AI-Doomer policy advocacy nonprofits. The AI Futures Project website says it is funded “primarily” by the Survival and Flourishing Fund, which says on its own website that it has advised Jaan Tallinn, Skype creator and one of the leading investors in Anthropic, to grant over $2.5 million to the AI Futures Project since 2024. Encode AI says on its website that it is ALSO funded by the Survival and Flourishing Fund, which in turn says that it told Anthropic investor Jaan Tallinn to grant $516,000 to Encode AI in 2025. And wouldn’t you know it, the Survival and Flourishing Fund ALSO says it told Jaan Tallinn to grant $2 million to the AI Policy Institute, the 501(c)(3) affiliate of the AI Policy Network, as well. What are the odds that the first three quote tweets of Coxon’s post would all be major AI-restriction policy advocates funded generously by the same donor, who also happens to be one of the leading investors in, and a board member of, Anthropic, the company Coxon was resigning from? And all within 15 minutes of posting (two within ten)? 3.) Jacob Coxon doesn’t have much of a resume, but we do know that, in 2022, he got a $20,159 scholarship for the “long term future scholarship program” from the Good Ventures Foundation, one of the philanthropic vehicles of Dustin Moskovitz, a notorious AI-doomer who has spent tens if not hundreds of millions on policy advocacy to strictly regulate AI, while also being an Anthropic Investor himself. It also just so happens that the 14th person to quote Coxon’s post was @MaxNadeau_ (27 minutes after posting) who is the program officer for the Technical AI Safety team at Coefficient Giving, another of Moskovitz’s philanthropic spending vehicles. Max is not a frequent poster, his last posts before quoting Coxon were before Labor Day, but he was remarkably quick off the mark for this one. 4.) Basically every major Democrat politician and candidate has suddenly glommed on to this post, and conveniently, as the people cry out foe answers, Bernie Sanders already has a bill written to “ban super intelligence” and regulate AI into oblivion, and will be releasing later this week. The bill, among many other things, will create “a new cabinet-level federal agency to safeguard the public from the dangers of artificial intelligence” that will be “advised by an Artificial Intelligence Advisory Board comprised of experts on artificial intelligence.” Do you think, perhaps, Anthropic and its many investors who fund AI policy advocacy might have interest in getting to place a pet “expert” on the board of an entity that dictates what AI is and isn’t allowed to do? And isn’t it fortuitous that this whistleblower came forward with his oh-so scary stories so close in proximity to the release of the most radical piece of AI legislation ever introduced?

A valid point, but doesn’t account for the truly enormous amount of post v13 work Tesla has put in testing and honing the model against real driver supervised miles. Where are the half million or so vehicles running this daily? Do we really think this new tech doesn’t need that?
