Isn’t @boomsupersonic casting their own blades and vanes for turbines?
Elon Musk says SpaceX is using its rocket-engine casting shop to make turbine blades and vanes, the parts that run 12 to 18 months behind the rest of the turbine, so it can bring power online 12 to 18 months faster than anyone else “So we’re casting the blades and vanes for the turbines. So SpaceX already has a very advanced castings capability that was developed for rocket engines." "So we have, I think, actually the most advanced casting capability on Earth, because the demands for castings for rocket engines exceed the demands for anything else you could possibly imagine." "So, taking that incredible team that has, I think, objectively the most advanced casting technology in the world and saying, hey, can you guys also make some blades and vanes for terrestrial turbines is much easier than what they have done in the past." "And when we talk to the turbine suppliers, they tell us that the blades and vanes are 12 to 18 months behind the rest of the turbine. Meaning they can deliver everything except the blades and vanes 12 to 18 months before they can deliver the blades and vanes." "So casting is this really difficult bottleneck. And if anything, it seems to be getting worse." "So that means that we can bring power online 12 to 18 months faster than anyone else." "That’s the kind of advantage that’s difficult to replicate. Unless someone else is building an advanced casting shop, they will be unable to compete with SpaceX in this regard.”

AI-generated fake documents grew 500% last year, and humans can no longer tell the difference That's why we’re launching Extend Verify, the first document fraud detection API built for agents Verify catches the fastest growing types of document fraud, including: - fully AI-generated documents - localized AI edits (down to a single modified character) - patched text, overlays, and in-painting from Photoshop, PDF editors, and coding agents - digital tampering after a document was signed - and many more In our internal evals, Verify detected over 96% of AI-generated and tampered documents. Verify is available today: extend.ai/verify/request-acc…

Replying to @kdaigle
Kyle, this is a classy move. Thanks for doing this! AWS re:Invent isn't at the same time or area, but we're setting aside 100 complimentary passes for folks with cancelled GHC registrations. While re:Invent isn't a replacement for GHC, I also hope that it will give folks a chance to connect Nov 30-Dec 4th, in Las Vegas. Please email [email protected]

Feature request for @bot I want the ability to group and collapse groups of bots and restrict whether they talk to each other (ok if they all talk to the captain) I have different projects and I need to keep them separate.

If I had one of these I would install a tiny electric train on the spine to send snacks to the back seat.
This is the "brass floating spine" center console in the new all-electric Jaguar Type 01. It extends from the front of the car all the way to the rear. Jaguar: "It accentuates scale and exuberance, creating individual spaces for the four occupants while opening up to reveal exuberant brass color stowage and cupholders and in Row 2 the control panel and air vents.​ Hot stone massage on the front-row seats underpins the sensory experience."

Children of Austin, send me your buy links! I will purchase any amount of lip gloss robots, bioengineered pizza topping, b2b saas… what do you got? Let’s kick Miami’s ass on the next one.
Kids aged 9–16 across 10 cities made $23,715.59 during Founders Weekend. Miami led the way, with 34 students making $12k. Across all 10 cities, kids were eager to turn their ideas into businesses, with our guides and mentors helping them decide what to sell and how to get their first customers. That’s what makes these weekends so fun. Kids get to find out whether someone will pay for an idea they’ve been thinking about, while spending two days surrounded by other kids doing the same. If your kid is always coming up with business ideas, give them a weekend to put one to the test. See if we're coming to your city and apply for an upcoming Founders Weekend (next one is October 24-25): founders.school/build-weeken…

Staying with delta because I *like* being able to tell people I’m completely unreachable for the next five hours while I sit in this chair in the sky and dive into this novel I’ve been wanting to read for six months.
Smart move. United Airlines is targeting unhappy Delta frequent flyers that are frustrated with slow in-flight Wi-Fi and the lack of @Starlink, offering to get matched Premier status through January 31, 2028. The status match offer ends on October 15: promo.united.com/offers/stat…

My Grok @bot project got its first feature request. A 93-year-old solver asked for printable pdfs of the solved grid. Made my day! ❤️❤️❤️
Hey homeschoolers! And parents of smart bored kids! I started a crossword site specifically avoiding old people trivia that regular crosswords are full of. Give it a try. Let me know what you think. New puzzles daily! nontrivialcrosswords.com/?ca…

I wish people would talk more about this. 99% of passkey deployments have neutral or negative security impacts.
Passwordless isn't the hard part anymore. Recovery is. Three ways teams quietly undo their own passkey rollout

Not to mention neutral or negative usability impacts - which is saying a lot because passwords were completely fucking unusable yet somehow passkeys are even worse.

When ENTJs have fucking had it with ENFPs
Can we please have this woman run for anything so that we can elect her and ultimately make her POTUS?

Tell me you don’t have kids without telling me you don’t have kids. Allllll of the school/hockey/dentist emails are written by AI now.
free-idea for any solo bootstrapper who's after an idea that will easily cross a million dollars a year. Integrate pangram (AI detection) with Gmail. Automatically block and report as spam any emails that pass a high confidence interval for any incoming mail written by AI.

Playing with jev for identity and access management standards!
The timeline is full of jev. So I pointed one at login and access. You type what you need, in plain English. The published projects that already do it climb out of the pile. Not a chatbot. No key. Runs on your machine. github.com/clawdreyhepburn/i…

Preach! 🙌
The "whiteboard defense:" I should be able to pull you aside at any moment and ask you to explain any customer-facing system you've shipped. You should be able to clearly explain how it works and defend the decisions you made. This is my benchmark for responsible AI usage. I don't expect line-level familiarity with the code. I don't care if you remember the exact function name or implementation detail. You may not even know it. I don't care. But if I ask "why did you do X instead of Y?", "what happens if this actor behaves maliciously?", "what data structure did you use here and why?", or "where does this fail?" you should be able to answer confidently. For PoCs, demos, experiments, whatever: I don't care. Generate 100% of it and understand none of it. Speed over quality every time in those specific scenarios. But if you're shipping customer-facing work, you can't be shipping things you don't understand at a high level.

We need to stop using LEAN to solve math problems and start using it to build mathematically provable sandbox boundaries that are enforced at runtime.
The best example of how the AI could go unaligned that I've seen.
