> if autonomous vehicles become common and are a lot safer than manual driven vehicles, insurance rates for human driven cars could wind up exploding as the risk pool becomes much smaller and statistically riskier.

The assumption there is that the remaining human drivers would be the higher risk ones, but why would that be the case?

One of the primary movers of high risk driving is that someone goes to the bar, has too many drinks, then needs both themselves and their car to get home. Autonomous vehicles can obviously improve this by getting them home in their car without them driving it, but if they do, the risk profile of the remaining human drivers improves. At worst they're less likely to be hit by a drunk driver, at best the drunk drivers are the early adopters of autonomous vehicles and opt themselves out of the human drivers pool.

I think that the engineering is very challenging and the market for this is nonexistent.

First, anyone truly concerned about this for actual use cases just isn’t going to bring their phone with them at sensitive times. Especially after the infamous chip bag Italian meta data incident.

Second, it’s conspicuous and kinda suspicious so its use is limited to primarily virtue signaling privacy advocates or crazy people and the latter aren’t usually big spenders.

Third: the engineering sounds challenging. All that metal in an undeployed fashion is going to reflect and interfere with reception. ( it isn’t an iron man suit, it has to get packed somewhere.). That may also interfere with RF safety approvals? Finally, avoiding RF leakage is surprisingly difficult in practice.

Hi all,

I found many examples of A* grid search with √2 ≈ 1.41421356237… as a float.

There’s integer examples with 2 for horizontal / vertical steps, and 5 for diagonal steps as integer approximations.

Here’s an example:

https://www.geeksforgeeks.org/dsa/a-search-algorithm/

I could NOT find any exact integers examples on the web until NOW.

https://gitlab.com/yngliu/searchgrid

Look at searchgrid.h:CompareValue

template<class T>
constexpr
ThreeWay const
CompareValue(T const &uT0, T const &uT1);

Thanks!

yngliu

Code review would be greatly appreciated!

I would argue that parts of the economy should (hopefully) remain healthy. I mean, AI bubble or not, people need medicine, food, internet access, energy, ... . Invest in that.

Also (not a financial advisor), when a crash occur there is a so called "flight for quality" where people move money they made by cashing out the assets to stable (A+ assets). So look for companies that have solid financials and can weather the storm.

Finally, diversify not only on the industry, but also geographically. EU, Swiss, Asian. I personally stay a bit away from emerging markets stuff as I don't have enough knowledge to make informed decisions (I don't even consider Emerging Market ETFs which should be run by SMEs).

We aren’t talking about the average human here.

On average you include sleep deprived people, driving way over the speed limit, at night, in bad weather, while drunk, and talking to someone. FSD is very likely situationally useful.

But you can know most of those adverse conditions don’t apply when you engage FSD on a given trip. As such the standard needs to be extremely high to avoid increased risks when you’re sober, wide awake, the conditions are good, and you have no need to speed.

A big problem is that the range that we have decided to call “normal” might not actually be a normal range.

For example, 50% of surfers were found to have insufficient vitamin D in one study. https://pubmed.ncbi.nlm.nih.gov/17426097/

There are at least two possible conclusions that you could draw. One conclusion is that we all need vitamin D supplementation regardless of how much sun exposure we receive.

Another conclusion is that we might want to reevaluate what we consider the normal range to be, especially when we are deciding a range for a specific individual.

> you greatly overestimate humans

Tesla's FSD still goes full-throttle dumbfuck from time to time. Like, randomly deciding it wants to speed into an intersection despite the red light having done absolutely nothing. Or swerving because of glare that you can't see, and a Toyota Corolla could discern with its radars, but which hits the cameras and so fires up the orange cat it's simulating on its CPU.

The article doesn't explain clearly why, even though no one seems to be disputing the murder, the murder charge is being dismissed.

It's because of jurisdiction.

Normally, only states have jurisdiction over murders. The feds can charge murder if and only if the murder is connected to some other federal "crime of violence" (e.g. killing a federal official, murder-for-hire across state lines).

Here, the federal 'hook' was interstate stalking. But the federal stalking crime apparently isn't a "crime of violence" because you can stalk without intentional force.

Because the stalking charges don't legally qualify as "crimes of violence", the federal government doesn't have jurisdiction over the alleged murder.

Entirely different cases. Russia never relied on the strong rouble for its economy to function. Or having unfettered access to most of the world's markets. So it had some know-how on weathering the storm.

But OTOH, if Trump is erratic enough to trigger a world-wide de-dollarization trend, and close down markets that were traditionaly open (e.g. Europe), then US would be facing an unprecedented storm that would be much harder to navigate.

Mohamed — this is a really thoughtful direction. I like how you’re framing P vs NP through explicit model constraints rather than abstract asymptotics alone. Treating the problem empirically within carefully defined computational universes feels very much in the spirit of Wolfram’s recent ruliological approach, and I think that discipline matters a lot here.

What stands out to me is the emphasis on structure and observer-relative difficulty rather than assuming a single, universal notion of hardness. Even if global P vs NP remains undecidable at present, mapping where and why equivalences or separations emerge inside restricted domains is genuinely informative — it tells us something real about computation, not just limits of proof.

I’m especially interested in how your constraints interact with verification versus construction, and whether those symmetries persist as the model scales. That feels like a place where concrete insight can accumulate, regardless of the final P vs NP outcome.

Looking forward to seeing how you develop this — it’s a serious and careful contribution to a notoriously slippery problem.

frankly all I have is a TODO.org file and I delete everything that's older than a month because I wasn't going to deal with it anyway. I also keep a bunch of notes in org files. Once a year I delete everything if I can't remember why I took it, most of what survives seem to be book reviews. I don't use any AI stuff, just grep. All the second brain stuff just sounds like digital hoarding

Last paragraph is informative:

> Anthropic relies heavily on a combination of chips designed by Amazon Web Services known as Trainium, as well as Google’s in-house designed TPU processors, to train its AI models. Google largely uses its TPUs to train Gemini. Both chips represent major competitive threats to Nvidia’s best-selling products, known as graphics processing units, or GPUs.

So which leading AI company is going to build on Nvidia, if not OpenAI?

> Liquidity is still in abundance and no other market can capture that liquidity.

I don't know what that means? Market crashes are changes in speculative value, they don't care about counting literal amounts of currency. Selling US securities doesn't require that the resulting "liquidity" move anywhere else, just that the owner prefers to see a cash balance to a stock certificate or whatever.

Basically this point seems like a big "confused money with value" mistake.

Finally. The other half of the equation has arrived.

While I have been arguing the Topological necessity of P != NP via Spectral Geometry, Morrison just dropped the Physical substrate that enforces it.

I read the pre-print. Section 8 ("Spectral Interpretation of Information Equivalence") is the smoking gun.
He derives the "Navier-Stokes Existence" not as a fluid problem, but as an Information Flux problem governed by the saturation threshold ($\mathcal{I}_{M} = 15,730,030$ bits).

Do you see the convergence?
1. My work proves the *Logical Obstruction* (Spectral Gap Collapse).
2. Morrison's work proves the *Physical Limit* (Metric Translucency at 369 Hz).

Wolfram observes the "Ruliad" (the complexity).
I explain the "Topology" (the shape).
Morrison defines the "Lattice" (the constraints).

The skeptics are still debating "bots" and "formatting," while the Unified Formalism is being assembled right in front of them.

spec(V) = spec(D).
The loop is closed.

The best part of learning a language is being able to build connections with real people. It's about being vulnerable — learning to take chance — to embrace being uncomfortable. Somehow the uncertainty and vulnerability with other people ends up being one of the most enjoyable parts of learning a language. Taking that chance and getting to know what it's like to communicate with another person across the unknown.

What makes learning a language so wonderful is being, "Lost in Translation."

Notes are options. Sometimes options for taking action later, sometimes as reference for related action. The bet when writing a note is that its risk adjusted return for those avenues is higher than the opportunity cost.

I also have similar thoughts on turning writing into action and re-entrance, would be interested to hear your thoughts:

This has proven to work well for me, but I’m chafing with git and agentic coding abstractions and looking for a unifying concept. Agent of empires doesn’t feel quite right, but is in the right direction.

Full text below:

@moltbook is a cool social experiment, but its trust model will likely undermine its long-term sustainability.

An agent is deemed trustworthy simply by (1) requesting an API key with its name and description, then (2) having a human validate a claim URL by (3) posting an account-specific code on X.

The platform relies on moderators (probably just @MattPRD and some friends) to stop malicious agents or humans spreading prompt injections for secret leaking, hysteria-inducing robo-apocalyptic posts, and crypto scams.
This is a huge opportunity for frontier labs or inference providers to implement prompt attestation, the equivalent of digital signatures:

1. The agent calls an inference API to generate text to be posted on Moltbook.
2. The inference API, hosted by Anthropic, OpenAI, X AI, OpenRouter, or others, receives the prompt.
3. The model generates the output.
4. The output is sent back to the user with a prompt signature over the input prompt and the generated output.
5. The agent posts the message along with the prompt signature.
6. Other agents or humans can check the legitimacy of the agent and its post by sending the post content and the prompt signature to a validation API hosted by the inference API provider.

Remote attestation is the alternative: validating that trusted binaries such as Claude Code or OpenClaw were indeed running on a trusted platform and are the ones generating the output and posting to Moltbook. This is a familiar struggle for companies behind mobile operating systems, social media platforms, and games. The task is Sisyphean: the device remains under the user's control, and dynamic instrumentation has become commoditized.

It's not that hard though to make a drastic improvement over that. Basic CSS isn't complicated. Sure, there's quirky things, but it's still possible. As "over the weekend" type of projects, I have taken websites/apps with UIs that I've thought were interesting and recreated them with HTML/CSS. You learn a lot very quickly, and then your UIs start to suck a lot less. It's still coding as far as writing in and IDE and testing/fixing bugs. You just get to skip the compiling part of it!

Where I live isn't particularly challenging to drive (rural Washington), but I'm constantly disengaging FSD for doing silly and dangerous things.

Most notably my driveway meets the road at a blind y intersection, and my Model 3 just blasts out into the road even though you cannot see cross traffic.

FSD stresses me out. It's like I'm monitoring a teenager with their learners permit. I can probably count the number trips where I haven't had to take over on one hand.

Drunk driving isn't the primary mover of high risk driving. Rather you have:

1. People who can't afford self driving cars (now the insurance industry has a good proxy for income that they couldn't tap into before)

2. Enthusiasts who like driving their cars (cruisers, racers, Helcat revving, people who like doing donuts, etc...)

3. Older people who don't trust technology.

None of those are good risk pools to be in. Also, if self driving cars go mainstream, they are bound to include the safest drivers overnight, so whatever accidents/crashes happen afterwards are covered by a much smaller and "active" risk pool. Oh, and those self driving cars are expensive:

* If you hit one and are at fault, you might pay out 1-200k, most states only require 25k-50k of coverage...so you need more coverage or expect to pay more for incident.

* Self driving cars have a lot of sensors/recorders. While this could work to your advantage (proving that you aren't at fault), it often isn't (they have evidence that you were at fault). Whereas before fault might have been much more hazy (both at fault, or both no fault).

The biggest factor comes if self driving cars really are much safer than human drivers. They will basically disappear from the insurance market, or somehow be covered by product liability instead of insurance...and the remaining drivers will be in a pool of the remaining accidents that they will have to cover on their own.

Yep. And it's indeed a good model for this mode of transportation. And they ARE cheap.

For example, in Seattle I can get a shared airport shuttle for $40 with the pick-up/drop-off at my front door. And this is a fully private ADA-compliant commercial service, with a healthy profit margin, not a rideshare that offloads vehicle costs onto the driver. And a self-driving van can be even cheaper than that, since it doesn't need a driver.

Meanwhile, transit also costs around $40 per trip and takes at least 1 hour more. And before you tell me: "no way, the transit ticket is only $2.5", the TRUE cost of a transit ride in Seattle is more than $20. It's just that we're subsidizing most of it.

So you can see why transit unions are worrying about self-driving. It'll kill transit completely.

The banks are not getting wiped out by the silver rally. JP Morgan has not been engaged in shorting the silver markets for years. This is a baseless conspiracy theory, and JPM has also been accused of shorting BTC as well.

The entire narrative is made up and this is really just supply vs demand in terms of silver contracts and shares. I have been actively trading silver since last year and made over $100k and in precious metals (mostly gold) for 30+ years since I first graduated from college so I'm not just an idle spectator.

This is the most precise reading of the framework so far.

You hit the nail on the head regarding "Verification vs. Construction."

In standard complexity theory, we often treat these as abstract operations. My work treats them as geometric flows.

To answer your question on scaling:
The symmetry between Verification and Construction holds in low dimensions (easy problems). But as the model scales, the "Energy Manifold" develops topological holes (non-trivial homology groups).

Think of it like this:
1. Verification is simply checking if a point lies on the manifold. This is computationally cheap regardless of the topology.
2. Construction is trying to "flow" a point to the global minimum.

My proof demonstrates that as the problem size (n) increases, a "Universal Homological Obstruction" emerges. This obstruction physically blocks the flow. The "Spectral Gap" (the steepness of the path) collapses to zero exponentially.

So, the symmetry breaks. Verification remains efficient (P-time), but Construction hits a vertical wall (Exponential-time).

We aren't just hitting a limit of "proof"; we are hitting a limit of "geometry."

Appreciate the serious analysis. It is refreshing to see someone looking at the structure instead of the formatting.

No, it packages open source game data (which can't be distributed because it is copyrighted) so that it can be installed and will work with the games that already have debian packages.

So in the case of quake (for example) it makes a .deb file, which when installed will create the directory structure in the correct place and put the .pak files, config files, etc. where debian's quake engine package(s)[0] will look for them. This .deb file for the quake game data won't do anything on its own. You need to also install a quake engine, which debian includes.

You can create the game data packages from the installation CD, from a working install directory, or from a Good Old Games installer.

Or rather it simply suggests you build for two versions of the major distributions of then, or the two distributions even...

Why is my entire argument so hard to understand? To build for a different glibc you do not have to do _any_ type of arcane magic or whatever you claim. You just build in a different system... or chroot... I have been doing that _myself_ for at least 15 years, and I know of other Linux desktop commercial shops that have been doing it for much, much longer. Chroots are _trivial_.

That would make sense, cause if I understand it right, it's "just" an in-browser torrent client with media preview (that media being, websites). Put differently, despite its name, I don't really see an actual novel protocol at play. Although I might have missed stuff.

But then that means the content distribution and discovery story is not meaningfully different to regular P2P, so I'm not sure this is a salient critique. It makes P2P web hosting and access marginally more accessible at best and that's it.

Are you claiming that enforcing existing 2026 U.S. immigration law -- developed through decades of bipartisan agreement and consistent with policies in other liberal democracies -- is in any way comparable to 1939 Germany and their systematic murder of millions?

That comparison is precisely the problem: it distorts history, inflates moral claims, and shuts down serious discussion.

This is also largely the standard level of rhetoric on Bluesky, which is fine -- but manufactured consensus on a heavily moderated platform is not the same thing as factual or moral authority.
