Yea what a Fall of Rome type dream - just look what happened when people overused a specific measure - we had Crowdstrike with around 8.5 million devices crashed to BSoD.
Identical OS, identical apps, identical updates, identical crashes at same time.

If you centralise then it is not the question "Will?" but "When?" it will fail.

The intermediary approach shifts trust rather than eliminates it —
you're trading provider visibility for intermediary visibility.
The more meaningful architectural question is what the intermediary
retains after the request completes.

Zero-retention at the inference layer — processing the prompt purely
in memory, logging only metadata (latency, verdict, rule hits), and
discarding the payload immediately — reduces the exposure surface
considerably. It doesn't solve identity linkage at the payment layer,
but it means there's nothing to subpoena, breach, or misuse at the
content layer.

For regulated industries this distinction matters a great deal.
"We never stored it" is a much stronger compliance position than
"we stored it but encrypted it."

> lack of density

One interesting question: what is "density"? Is it number of people per road-mile? Number of households? Structures? Sales tax revenue? Property tax revenue? Property value per road mile?

LA has somewhat insane property values right now, and by the metric of millions of dollars of residential value per road-mile, I think one might imagine the density to be sufficient to afford decent streets. Of course, that does not translate to municipal budgets or even to disposable income of the owners or the residents in those properties.

What does what look like? Approval voting? The unacceptable (usually extreme) candidates fail to get votes and so get booted out of office, with their places taken by more moderate, common-sense candidates.

FPTP, particularly with partisan primaries, has the misfeature that you need to rally the base in order to win the crowded primary field. This leaves only extremist candidates heading toward the general election. In a country like the U.S. where voting is not compulsory, this turns off the moderate electorate, who are forced to choose between two extreme candidates that both seem batshit crazy, and encourages them to stay home.

Strange article. Even though I do like music and engineering.

>Electromagnetic pickups—(...)—fixed the loudness problem. But they left a new one: the envelope

Was it really a problem to be solved? Good tube amplifiers already existed back then. Clean guiar tone was not something frowned upon.

>Hendrix’s mission was (...)

>His solution was (...)

I don't think Hendrix was on a 'mission' to solve engineering puzzles at all. He was just experimenting, as an artist.

Your framing is interesting. You may feel that you can’t change who you are in real life, but people have a choice on how they behave online (or choose not to engage at all). So you could choose to be nice (or at least not a jerk); I’m pretty sure you wouldn’t get people writing to your employer complaining. I’d argue that if you know you’re sometimes a jerk, it’d be less stressful for you and others if you didn’t bring that energy online.

> Honestly, there aren't that many crazy people on the SF Muni/busses. The detractor for taking these services is speed and frequency.

Everyone can form their own opinion on the acceptable number of visibly intoxicated people they’d like to encounter. That said, my understanding of the law is that the correct number is zero. So seeing more than zero is an indication that laws are not being enforced.

People can debate whether particular laws regarding drug use are justified. However, if enforcement itself is optional, one might reasonably question whether that applies to other, less controversial laws as well.

"High-quality code can be a joy to extend and build upon." I love the analogy here. It is a perfect parallel to how a good 3D model is a delight to extend. Some of the better modelers we've worked with return a model that is so incredibly lightweight, easily modifiable, and looks like the real thing that I am amazed each time.

The good thing about 3D slop vs. code slop is that it is so much easier to spot at first glance. A sloppy model immediately looks sloppy to nearly any untrained eye. But on closer look at the mesh, UVs, and texture, a trained eye is able to spot just how sloppy it truly is. Whereas with code, the untrained eye will have no idea how bad that code truly is. And as we all know now, this is creating an insane amount of security vulnerabilities in production.

Scott Wiener is my state senator. My point is exactly that many California cities are being forced to allow density, instead of just coming to that conclusion because it's a responsible one.

They don't want it, even if they need it. They're kicking and screaming and doing anything they can to stop it, while at the same time their city budgets are in the toilet. The only thing that's actually driving this reform is that housing prices are out of control, so you have a large demographics of people fighting to increase density.

Where this is not happening is everywhere else (think: Texas, Florida, North Carolina, Virginia, Arizona). Those areas don't have the same demand for density, but they still have the same long-term structural deficit problems.

I know exactly what you mean, I've been there myself so many times that I have learned be humble just for this one reason. I have a post about good engineers being humble which is based on this idea.

If you think this way, you are already on a good path. Think that there's a lot of folks that don't even care at all, you do care and want to improve, that sets you apart.

Np. Still learning about how to reference agentskills from my coding LLM here. Haven't yet worked with MCP or A2A much. I should port instruction prompts from each project's AGENTS.md to reusable skills in .claude/skills/skillname/SKILL.md ; so that I can reference "/skillname" in a prompt to reuse that prompt text.

Copilot looks for agent skills in .claude/skills/, .github/skills/, or .agents/skills/ .

FWIU there are package managers for agent skills?

PAKS:
https://github.com/stakpak/paks

vercel-labs/skills:
https://github.com/vercel-labs/skills :

export DISABLE_TELEMETRY=1
npx skills add vercel-labs/agent-skills

https://skills.sh/docs/cli

A reproducibility, traceability, and auditability concern:

How to show the text of the exact version of the skill referenced in each input prompt in each chat log? GH copilot's JSON export format is a fairly complete trace compared to e.g. Gemini Chat.

.

ElasticSearch (Java) and Meilisearch (Rust) do at least porter stemming before indexing.

MeiliSearch can be used as a vector database for langchain.

Show HN: Tesseract – 3D architecture editor with MCP for AI-assisted design
by infrastellar | 2026-02-25 23:05:46+00:00
Hey HN. I'm David, solo dev, 20+ years shipping production systems. I built Tesseract because AI can analyze your codebase, but the results stay buried in text. Architecture is fundamentally visual — you need to see it, navigate it, drill into it. So I built a 3D canvas where AI can show you what it finds.

Tesseract is a desktop app today (cloud version coming) with a built-in MCP server. You connect it to Claude Code with one command:

claude mcp add tesseract -s user -t http http://localhost:7440/mcp

I use it for onboarding (understand a codebase without reading code), mapping (point AI at code, get a 3D diagram), exploring (navigate layers and drill into subsystems), debugging (trace data flows with animated color-coded paths), and generating (design in 3D, generate code back).

There's also a Claude Code plugin (tesseract-skills) with slash commands: /arch-codemap maps an entire codebase, /arch-flow traces data paths, /arch-detail drills into subsystems.

Works with Claude Code, Cursor, Copilot, Windsurf — any MCP client. Free to use. Sign up to unlock all features for 3 months.

It's early but stable. I've been dogfooding it on real projects for weeks and it's ready for other people to try.

Docs: https://tesseract.infrastellar.dev/docs

Plugin: https://github.com/infrastellar-dev/tesseract-skills

Happy to discuss the MCP integration, the design choices, or anything else.
Would love feedback.

There are definitely up- and downsides. This is all much trickier than I think people realise, with complex second and third order effects. (Some that I haven't even mentioned. A more nationalised Internet will hurt smaller countries, for example, that cannot create services on par with US juggernauts. It will harm third countries that are neither the EU or the US. It will weaken the West's collective influence vis-à-vis China, Africa, etc.)

I don't know what the optimal course of action is.

> The marginal cost of a housing unit is vastly higher than the cost of building that unit.

The cost of building a housing unit is rather out of control in LA right now, due to a number of factors. Some of those factors involve permitting, but some involve complexities of complying with building regulation, and there is also insufficient availability of contractors and insufficient availability of labor.

I've been shocked by how much my rural / politically red city (pop ~80k) here in California has moved on this issue over the last 5 years. Doubled the allowed meters per lot, super relaxed ADU rules and city + developer funded 5 over 1's in the renovated city center for some impressive density. Also all the new construction for restaurants or whatever in the area requires adding apartments above. Not to mention a massive initiative for safe bike paths from the commercial areas to the park trails. They also bought some longtime closed hotels and converted them to housing for homeless. Really big stuff and huge quality of life improvements.

I just read about the backstory. Gaff (Edward James Olmos) put the unicorn where Deckard would find it as a message. He was gently informing Deckard that he was a replicant. Deckard had just dreamed about the unicorn and told nobody, so the only way Gaff could know is if he knew which dreams Deckard had implanted in his memory.

This came from Ridley Scott, not Philip K. Dick.

I am impressed that Scott was so subtle about this for so long. It would have been a short-term boost to hit us over the head with it, as in The Sixth Sense. But being coy about it helped to make the movie a true classic.
by socalgal2 | 2026-02-25 23:06:46+00:00
I'm of multiple minds about this. I like high density. I like a car-less lifestyle of the last 30 years I lived without a car.

That said, currently I live in West LA. Traffic is atrocious! Doubling or tripling density will make it even worse, probably exponentially worse. Adding non-car transit options just isn't in the cards in any reasonable time frame because of all the people that block construction and because the USA, like most countries, refuses to setup a win-win situation for transit (like Japan) and instead continues to insist it be government based and therefore most likely to go over budget during construction and then under budgeted during operation.

At the same time, I wish our entire coast was 30-50 story high-rises. It's ridiculous to me that only a few elites get to view the ocean from their homes on the coast and everyone else is shut out because no one is allowed to build the high-rises.

Maybe I missed something, but I see little evidence that there is a concerning ability to deanonymize. Many people post under a pseudonym but then link to their GitHub etc.
In fact by construction the HN dataset _only_ consists of people who are comfortable with their real identity being linked to it.

The real question is whether someone who is pseudonymous and actually attempting to remain so can be deanonymized.

In no capacity do these create clean topo, textures, and uvs. If you do not believe me, use the reference image from the post and upload it to Meshy or Tripo and see what happens. Yes, slightly better than the open source Trellis, but still nearly impossible to work with and a model you would never put on any slightly serious eCommerce site.

We've tried them all. If one existed, it would save us money, speed up our pipeline, and trust me we'd be using it.

If you think about it, Wordpad was always just the free "lite" edition of Word for people who didn't buy Office to use. Like Outlook Express was to Outlook.

But in the world we seem to be heading toward, where you can only log into Windows with a Microsoft account, and where your Microsoft 365 subscription state controls which "edition" or "desktop experience" of Windows you get as said logged-in user (regardless of which machine you're logged into)... there'd be no need for Wordpad.

In that world, Word the software package would always be pre-installed. (Why? Because even if you aren't paying for M365, someone who is could always log into your PC as a roaming user; and that person would want Word to work immediately without having to wait for it to download+install.)

And in a world where Word the software package is always preinstalled, then Microsoft could just let anyone launch Word (whether they have an M365 subscription or not); and then, at launch, rather than just putting a paywall in the face of anyone without an M365 subscription, Word could instead use the logged-in user's M365 licensing state to determine whether the spun-up Word process should run the full-fat Word UI, or some kind of degraded unpaid-mode Word UI.

And "Word running with some kind of degraded unpaid-mode UI" could be every bit the "Word lite" offering that Wordpad is. Which makes Wordpad itself redundant.

(The only weird part to me, is that they deprecated/removed Wordpad before pulling the trigger on all of this.)

Hadn’t seen that before! Seems very in line with what with the broader points about regularization. In table 4 they show faster convergence in 200 epochs when used alongside REPA. I’d be curious to see if it ended up beating REPA by itself with full 800 epochs of training — or if something about this new latent space, leads to plateauing itself (learns faster but caps out on expressivity). We’ve seen that phenomena before in other situations (eg UNET learns faster than DiT because of convolutions, but stops learning beyond a certain point).

> This is about the idea that a falsity is "not up for debate".

Your assertion that there's "no comparison whatsoever" is of course not, when there's ample.

> who isn't here to try to explain himself

Lets just say that social norms & experiences drive much of what people believe in. One of Leibowitz's student goes:

"I hated the notion of occupation since the very beginning. My first memories from after the 67 war are traveling with my children in the occupied territories. There were awnings over groceries stores with Hebrew lettering advertising Osem noodles. I couldn't bear it. I thought that was dreadful because I remembered German lettering in France. I have very strong feelings about Israel as an occupier."

We can guess what their "very strong feelings" might have been having experienced Nazi occupation of France during WW2.

Because they're not trying to build a leading coding agent - they're racing to AGI. That means cramming everything and anything, from every angle because general intelligence is happening next year and that'll connect all the dots, leading to hypergrowth and complete industry dominance, across all domains.

Seriously, if you listen to Dario talk, it's non-stop how there's a tsunami coming, people have no idea of what's ahead, how general intelligence or superintelligence is right around the corner. But also, this is super dangerous, and only Anthropic can save us from a doomsday scenario.

I really like this framing of 'Internal Agency.' In 3D, that lack of a 'Seed' is exactly why a model fails when you try to animate it. A human modeler understands that a joint needs extra edge loops to bend correctly. It has 'intent' for the model's future. The AI, performing a 'Statistical Harvest,' only cares that the surface looks right in a static frame. It provides the 'Illusion of Completeness' but none of the functional DNA required for a production environment.
by scoofy | 2026-02-25 23:11:31+00:00
The Strong Towns argument is effectively talking about density as tax-revenue per road mile liability, and trying to keep that positive. Areas with high liabilities (sewer, water, buried electric, fiber, etc.) need to have higher tax-revenue per mile (more people, more businesses, etc) to support that infrastructure.

There are other ways around this though. If you force your citizens to maintain their own septic and well water (or even small-pipe potable water), and have unsurfaced roads, then you can do with much less revenue-per-road mile.

The point is that the federal government usually pays for the infrastructure up from (as an "investment"), but when that subsidized infrastructure is a net money-loser in the long run, cities growing actually makes the problem worse.

>very peak of Chinas demographic dividend

No, 2000s-2020s was peak blue collar dividend, think world combined, but low value dividend. When PRC had lots of hands but few brains, i.e. fraction of STEM vs US / west.

2040s-2080s is PRC peak tertiary skilled dividend. They'll have about 2-4x US in just STEM who'll be in workforce for most of our and our children's life times, even while tfr math starts eating away at future cohorts. The TLDR is they've just started cooking, their highend human capita pool will be exploiting greatest high skill demographic dividend in recorded history for high value. Their final form is OCED combined in talent and world combined in bluecollar backstopped by robots/automation (currently on trend to be more than world combined).

Brain drain barely a problem now, this isn't 2000s where there's shit domestic opportunities and PRC lose large % of the few best they produce. They now they mint so much talent, brain drain a rounding error, top talent increasingly stay in PRC. And many of the best that went abroad are returning. Or future trend is many of best that are leaving will recirculate back to PRC eventually. TBH most of those go abroad now are frankly PRC B/C tier talent, i.e. most international students are those too mid to do well on gaokao and even then they turn into A students in west. Like there's still some sectors where west can draw because they can afford to pay magnitudes more (which is matter of FX/geopolitics), but PRC now also in position to attract foreign talent via $$$, so much so that places have to ban nationals from working in PRC strategic sectors. China's expat draw is it's PRC, if you're high end talent and you want lab built in a few months, bottomless access to resources including human capital, dynamism of Asian tier1 cities, that EU+US can't offer. But immigration point really secondary to fact that when PRC produces plurality of high performing global talent, and retains most of them, they don't need to worry about immigration of competent people, just need to hold on people they have, which by and large is happening, i.e. Tsinghua brain drain rate went from 30% to single digits in last few years and returnee rate higher than ever. As in west depend on PRC talent surplus (because western talent pipeline shit vs PRC), trains them, and now that PRC rich with opportunities, many recirculate/reverse braindrain back to PRC anyway when they're high level.

At end of the day _most_ people are economic migrants, they move for $$$ not muh freedom/community. Ultimately US/EU strength is they have money/FX money multiplier, US way more than EU. When that goes away/decline people start making different choices. And again, PRC demographics will be lingering in background... but just means cheaper housing/less crowded cities, i.e. less drag on PRC living. It terms of active demographic dividend, most of us will be dead before PRC declines, imo not really worthwhile extrapolating on that timescale.

Bus lanes still seem like the thing people who hate cars propose to intentionally screw over the people who have them. "Hey, we have this road with two or three lanes in each direction but it's fairly congested. Each of the lanes is carrying something like 50 cars per minute during the day! Why don't we impound one of them so we can have a bus carrying 40 people drive on it once every 15 minutes?"

If you have enough density to justify a bus lane, you have enough density to justify a subway.
