Correct. I deeply pity anyone whose soul is so dead that they can watch a car do a barrel flip on cold-gas thrusters and only think "what is this good for"?
I do wonder that, myself. But because my soul is not dead, I questioned the utility only *after* reveling in the sheer audacious awesomeness of what I had just seen.
Some things you should do just because they're crazy cool.
"Why did they waste so much time making a flying car no one can use in the real world?"
Because not everything is about whether you can imagine it being useful to you. Because like art, sometimes we make things for the glory and challenge of making them. Because we don't know if what we'll learn will make your toaster work better and you'll never realize it because you take for granted that things get better without thinking through how that happens. Because you can't inspire people with toasters, but a barrel-rolling car that can drive upside down is absolutely setting someone on fire right now.
I'm not a car person and you shouldn't trust me with a rocket, but I want a roadster because I make art and that thing is absolutely a thing made for love and passion and I get that in my heart.
(Also because I'd look really cool in one.)🤣

In 1983, an 80-year-old Navy admiral held up a piece of wire and proved that almost every engineer in the room had been lying to their bosses about the speed of their own computers.
Grace Hopper cut the wire to 11.8 inches — the maximum distance light can travel in one nanosecond. Anyone who quoted a chip speed in nanoseconds without knowing that number didn't actually understand what they were selling.
The wire wasn't a teaching prop. It was a public test. Generals and executives had been nodding along to "nanosecond" for years without being able to picture one — she made the invisible unit something you could hold, and something you could be caught not understanding in front of a room.
42 years later, computers run in picoseconds, a distance a thousand times shorter than what she was cutting, and nobody hands out the proof on live TV anymore.
Readers added context they thought people might want to know
Grace Hopper's wire demonstration was a longstanding educational teaching aid she used from the late 1960s to help audiences visualize nanoseconds and signal delays, not a 1983 public test proving engineers lied or were caught not understanding.

Allow me to interpret what’s happening.
Anthropic is being audited.
Anthropic desires to file an S-1, as they would like to go public. Therefore they need an audit. And by “they”, I mean the VC’s who invested in them. So “they” can exit their position and pass the bag to firemen, nurses, teachers and policemen.
How does this go from the VC’s to the working man and woman? Because the size of the IPO will automatically qualify Anthropic for the Fortune 500 and the Dow Jones 100. Therefore, every working person with a 401k or pension will end up owning a little bit of Anthropic in their mutual funds. Teachers hold the bag, VC’s take the cash. Thank you, come again.
Now back to the audit. The audit required is a PCAOB audit, Public Company Accounting Oversight Board. This audit is what all public companies must comply with be on the stock market. Revenue recognition, expense classification, depreciation, related party transactions, etc. It’s there for consumer protection.
This audit is TOUGH. It is INVASIVE. There is no way to lie your way through it. Any company that passes a PCAOB audit automatically earns my trust on finances.
How do I know? Because I’ve been through it before. @ChangRobotics is 2 year PCAOB audited and currently underway for a 3 year audit. It’s brutal. The same as showing up as the valedictorian to your high school graduation, except you’re naked, and you have to walk on stage and deliver the speech. It’s rough. And I know many incredible founders that can’t pass one.
Now, why would Anthropic be leaking all kind of weird statements lately about “self pacing” a slow down on AI (e.g. they are WAY behind on revenue), and profitable if they didn’t have expenses (e.g. we just learned for the first time what our expenses are, because we’re being audited).
Because they were claiming NVIDIA discounts and Microsoft cloud credits as revenue. Because they had no clue what their expenses were, or why it even mattered. Because they had unlimited investor capital and their job was to burn it to make an LLM. Well, they did a great job with that!
That’s the same as my wife coming home with Bed Bath and Beyond coupons and telling me it’s her paycheck. Ummm, not the same, sweetheart.
So by now hopefully you can see that Anthropic is in a PCAOB audit right now, in order to file an S-1 and go public, and pass the bag to teachers so the VC’s get profits. And hopefully that explains their “crazy” behavior.
In reality you can be grateful to KPMG, PWC, or whoever is auditing Anthropic, because it’s the first time Dario learned that:
1) we are not profitable
2) expenses matter
3) coupons are not revenue
4) we have no clue how to be “profitable”
5) growth is hard when revenue numbers are in an audit and not a power point

RSA-260 appears to be factored.
- That means the specific 260-digit RSA Challenge number is broken.
- RSA-260 is 862 bits; the previous public general-purpose factoring record was RSA-250 at 829 bits.
- It does not mean RSA-2048 is broken.
- The biggest question is how the factor was found: conventional GNFS, a major optimization, or a genuinely new method.

That's a small reminder! 👇
As of June 2026, HTTP has a new method - a GET with a `body` 😎
Meet QUERY (RFC 10008).
It lets you send complex queries in the body (like POST) while staying safe, idempotent, and cacheable (like GET). Already works on servers (Node.js, Go, Laravel…).
Browsers are still adding full support, usable now with care, with widespread adoption coming later in 2026+.

The NSA kept 1 lecture in a vault for 40 years. In 2024 they released it. It's Grace Hopper explaining the future of computing in 1982.
The channel that posted it: the National Security Agency's own YouTube.
Hopper stands at a podium in Navy uniform, a captain, and talks to a room of NSA staff for 90 minutes across 2 reels.
The title: "Future Possibilities: Data, Hardware, Software, and People."
She compares the computer industry to the early automotive one, all custom parts and no standards, and argues software will become the hard problem, not hardware. She was right by decades.
She invented the first compiler and gave COBOL its shape. She kept a clock that ran backwards on her wall to prove rules can be questioned.
The tapes were too degraded for normal release, so the agency restored them before posting.
40 years in an NSA archive. 90 minutes. Now free.

I am old and was around for Sun's demise. Aravind's reasoning is 100% true. Sun sold web servers that cost a million dollars each, with expensive services wrapped around them. They could do incredible things small Linux servers could not. For example, you could hot swap cards out of a Sun server WHILE it was running.
But a fully loaded Linux web server cost maybe $10,000, so you could buy ten and still save 90%. People rushed for the cheap Linux boxes. Sun tried to adapt, but the whole org was built around million-dollar servers. They just couldn't change. This all happened very quickly, about two years if I recall correctly.
Lots of parallels to expensive cloud AI and local AI. If Kimi K3 ships open weights as promised, you could run it on a couple of future Mac M5 or M6 or M7 systems (whatever ends up shipping) for maybe $50,000.
And local AI is the worst it will ever be today. Think where it is in two years. I don't think Fable 5 at $50/MTok output is sustainable.
At its peak, Sun Microsystems was valued at 205B (394B if inflation adjusted). Sold software in enterprise servers. Got disrupted by Linux, x86, and commodity hardware. Ended up selling to Oracle for 7.4B, losing 96% of its value.
Open source models running on local hardware can have a similar impact given what’s going on.

A Scottish audio company, famous for their turntables, once invented a CPU architecture.
Their internal software kind of sucked.
Somehow along the way, the company became convinced that the problem was not from their programmers being bad.
No, instead the (logical) conclusion was that all traditional Von Neumann-style computers were WRONG. Linn (the audio group) needed to develop their own design, which became known as the Rekursiv.
Honestly, if you can get past the insanity it’s actually quite admirable. The whitepaper is clearly written by some (very) stubborn engineers; it’s like the opposite of RISC, no visible memory addresses, everything’s an object, auto GC, etc.
Oh, and they wrote their own programming language to go with it, of course (Lingo).

I’m excited to announce that @CapitalOne is open-sourcing VulnHunter, an advanced agentic AI security tool we built to help the entire developer ecosystem find and fix software vulnerabilities.
The digital threat landscape is moving faster than human defenders can keep pace. Because modern supply chains are deeply interconnected, a single vulnerability can ripple across thousands of enterprises simultaneously. No single organization can solve this challenge alone, and stakes are only rising for security teams to fight AI-enabled threats with equally capable AI-driven defenses to protect our digital environments.
We designed VulnHunter with a developer-first mindset to solve a massive industry pain point: overwhelming false positives that create friction and slow down daily workflows. VulnHunter represents a new approach through three primary technical innovations:
-Falsification Engine: It actively tries to disprove its own findings to virtually eliminate false alarms.
-Attacker-First Analysis: It simulates a hacker's journey, tracing entry points to map real attack paths.
-Evidence-Backed Repair: It generates the exact code changes needed to fix verified defects.
I’m incredibly proud of our internal team for exemplifying Capital One’s culture of innovation and invention. I’m also appreciative of our partnership with @AnthropicAI. VulnHunter’s advanced reasoning workflow is optimized to run using the exceptional capabilities of Claude Opus 4.8 and the Claude Code environment. It’s a noteworthy milestone in our collaboration, and I can’t wait to see how we’ll continue to create state-of-the-art capabilities together.
At Capital One, we hope the release of VulnHunter enables the broader tech and security community to inspect the workflow, challenge its assumptions, and contribute improvements. Collectively using and contributing to these solutions can help advance the betterment of the systems we all build and the customers who depend on us to keep their data safe.

Claude just became a craacked video game designer.
With the launch of Unreal Engine's MCP server last week, you can now build entire video games just by talking to Claude.
I spent the past few days building with it, and I'm telling you, this is going to forever change how video games get made and who gets to make them.
In this video I show you exactly how to set up the Unreal Engine MCP yourself and run through three demos: building a full playable city, cloning a real city from Google Earth, and creating custom buildings in Blender.
Here's the agent harness I mention too: github.com/per-simmons/unrea…

This guy collected every local law in America and put them in a single database.
2.2 million laws.
This might seem to you like some nerds side project, and while it is technically, it is also much more important than you think.
Historically, whenever anything is made transparent to the voting bloc it undergoes radical change.
Every. Single. Time.
To the extent governments work overtime to make things opaque. (And I expect that to happen to this dataset too very soon, in a thousand different ways.)
The internet makes everything including politics “global/local” and local laws won’t escape.
It’s hard to understand right now how profound this will be, but we live in interesting times for sure.
Thank you Joe, and all the other nerds who do stuff like this because they are personally curious and they can. This is how history moves forwards
New paper: every law in America is technically public. But not really, until now!
With @DenisPeskoff at UC Berkeley, we built a corpus of ~every publicly accessibly city and county law, and released a huge chunk of it!
2.2 million laws, you're (probably) covered in it!
