Look at the map in this linked article (1). Seems like southern states are the ones getting most subsidy. Midwest for the most part relatively lower on the spectrum.

And what is even the subsidy? Interstate road works? Hardly matters to your daily life. The other subsidies are probably things like welfare benefits or medicaid, which might be a significant thing in your daily life if you qualify but if you don't are also irrelevant.

Lower property prices on the other hand lift all boats. Renters benefit. Homeowners benefit. Corporations benefit. At every income level in the market.

https://taxfoundation.org/data/all/state/state-federal-aid-r...

I really don't think subsidy is a factor in keeping things cheap in terms of cost of living. I think it is pretty solely due to the relationship between the size and rate of growth of the local high income demographic and housing inventory. For example it is even cheaper to live in Mexico due to this relationship, and there is probably a lot less subsidy going on there.

Once you have everything figured out, you just keep using the config you have. It might be worth the investment. I stopped using oh-my-zsh when I realized it was what was causing multi-second delays on Raspberry Pis.

I think auto suggestions and syntax highlighting plugins can be installed separately from oh-my-zsh.

I use starship for a better prompt, and it works on more shells than just Zsh.

I also have Atuin installed to share history across machines, and as a benefit the history search is a lot more powerful.

Crashes, various points over the last few decades. Three fender benders but the guy in Istanbul managed a proper one at speed, early hours of the morning and going too fast in the rain - thankfully nobody hurt but his car was trashed.

Robberies, both 2012, on the same trip.

And yes, corruption still rules the roost in a lot of old eastern bloc countries, from the government to the cops to the babushka driving the bus - it will take a long while for the mindset that the USSR inculcated to dissipate - that is, that the only way to get ahead in life is to lie, cheat, and steal. 2012 was my first time east of the Urals, and these days I know far better how to deal with it than back then, when I was still wet behind the ears.

"The LLM system's core mechanism is probably a "propose-verify" loop that operates on a vocabulary of special tokens representing formal logic expressions. At inference time, it first proposes a new logical step by generating a sequence of these tokens into its context window, which serves as a computational workspace. It then performs a subsequent computational pass to verify if this new expression is a sound deduction from the preceding steps. This iterative cycle, learned from a vast corpus of synthetic proof traces, allows the model to construct a complete, validated formal argument. This process results in a system with abstract reasoning capabilities and functional soundness across domains that depend on reasoning, achieved at the cost of computation required for its extended inference time."

I've got multiple degrees, and the presence of an MBA invalidates my opinion?

I'm serious when I say this is not just "MBA think", this is everywhere. People are being short sighted. People are not thinking things logically through, and this is widespread.

Yes, we're talking physical goods. Items where short sighted thinking destroys brands, exactly what the original post discusses. It's too easy to just blame the MBAs. This is a widespread issue that is not just in physical goods, it is at the core of what is required to sustain democracy - a critical thinking population. We've educationally failed the population en mass by not having education verticals that stress perspective. We only teach short term perspectives as meaningful and worth action, and all this is coming home, today.

Those that should be able to talk sense in the critically short sighted decision makers have not been taught how to make their points and be understood. That is real, and widespread. Continue to label the cliche and get no where. We need to recognize this critical failure, because it is destroying one hell of a lot of foundation we need.

> "compile-time hierarchy of encapsulation that matches the domain model"

The talk doesn't mention it of course, but this still exists, even in "modern" languages that purport to be free of OOP! What do you think Typestate is - particularly in its genericized variety - other than a kind of "compile-time hierarchy of encapsulation that matches the domain model"? Change my mind: Typestate - and Generic Typestate only more so - is just good old OOP wearing a trenchcoat.

> But it hasn't solved the issue of having the vast majority of merchants accepting crypto, the issue of crypto price volatility (or associated risk of stable coins), or the friction/unreliability of turning cash into crypto.

The price volatility seems like a red herring. If you're using it as a currency then you're not holding it for significant periods of time and the entire point is to make it an automated process, so you're buying some cryptocurrency for cash and then immediately spending it. How much volatility do you really expect in the timespan of a fraction of a second?

Meanwhile the conversion shouldn't be a hard problem. You have a service that allows you to buy cryptocurrency with a credit card or bank transfer and then an app that uses that service to buy cryptocurrency and transfer it to a merchant that accepts cryptocurrency, and then any merchants being unfairly targeted by the payment networks can do that. And the cash to cryptocurrency service can be operated by a different party than the app so the former can't be assaulted for having the wrong customers and the later isn't directly interacting with the payment networks.

I suspect the real problem is this: The chargeback process for credit cards isn't compatible with anything where the merchant is delivering fungible goods to the customer that they can't feasibly recover if the customer was using a stolen card or issues a fraudulent chargeback, and cryptocurrency is one such thing. So then the service that allows you to buy cryptocurrency with a a credit card gets screwed, because customers issue a chargeback to them or use stolen cards on their service even though they actually provided the cryptocurrency as promised.

Which is a huge existing problem with the payments system. The payment networks dump the cost of fraud onto innocent merchants and then lose the incentive actually prevent it even though they're the only ones in a position to do it, e.g. by issuing chip cards that could be read by any ordinary PC/phone via open standards and therefore enable "card present" transactions to happen over the internet.

And then if you expect cryptocurrency to solve that problem, it can't do that on the side of the transaction where the cryptocurrency is the thing you're buying.

I don't see another option. We already have the gov going down far worse roads of papers please and secret police. I at least want the some of these corrupt rich people to go down with the ship.

I used to view the mcarthy era of communist purges as a bad thing that harmed many innocents. But if we are going to throw out due process and habeus corpus anyway? I want the MAGA and donors like musk hunted like any communist was. And their children and grandchildren on watchlists . Just like the commies.

At my gliding club there is an older glider with a large toggle switch on the panel. That switch is labeled "BUGS". Always amuses me...

The "BUGS" switch is an input to whatever that glider uses for a flight computer. A single bug splat disrupts the laminar flow and significantly reduces the performance of the wing in that spot. Enough splats and you have to let the flight computer know that the performance of the glider has significantly decreased. In practice that affects things like the final glide calculation. Without the adjustment you might think you have gained enough altitude to get back to the gliderport without having to climb again, but you could end up a bit short.

It's not the animation itself that does anything magical, but the afterimage (I think that's what you would call it?) your eye produces after you stare at the dot for long enough. The black bar is just a countdown timer for the impatient.

But try to maintain laser focus on the central dot, not letting your eyes move or blink if you can help it. Once the black bar depletes, the circle should start shrinking, and around its periphery (like an eclipse) should be some incredibly vivid, super saturated colors.

... and what I post to Mastodon/Bluesky is different from what I post to HN

https://mastodon.social/@UP8

For instance, I post links to phys.org a lot more and I'm less likely to post a link to the paper because (1) Mastodon can't extract images out of the latter and (2) I get more replies like "this is over my head" from Mastodonsters whereas I think most of you might think you'd look stupid if you said something like that. On the other hand I rarely post links to The Guardian to Mastodon because it can't extract images from Guardian articles.

Bonus: if you look right now you'll see the user interface that I use to post to HN! [1]

Can we talk about hacking, this being hackernews?

A few comments claim the sensors can be triggers by non-smoking events such as hairspray, nail polish remover, perfume...

If that is accurate it seems to me one could exploit that sensor flaw by purposefully triggering a false positives with some benign action - and video record doing so - perhaps a couple of times.

Then if and when smoking is alleged, obtain a log of the alleged event times, then provide video evidence that debunks at least one alleged smoking event.

A relatively small number of activists could probably create a viral nightmare for Hyatt and anyone else implementing this system.

Disagree.

You want them rigidly held in place as *any* flex in their mounting will add up to fatigue failures over enough time. Realistically, that means glue or a screw-down anchor that exerts tension--and if you have such an anchor you need to beef up the substrate also to avoid it deforming the case over time. Glue is thinner and lighter, thus it wins in the market. Likewise, cases are glued because providing waterproofing via glue is thinner and more reliable than providing it by gaskets and screw-down anchors.

Simple observation: I have a chest strap heart rate monitor, uses a coin battery and is rated for swimming. What's the biggest failure mode? Imperfect seal of the gasket against the stuff around it permitting water intrusion. (There is a redesign that is supposed to be more reliable but since mine never gets submerged it's still working despite once I found the gasket was clearly not properly seated.)

Consider the average american life over the last 100 years and how power demands changed. We went from gas to induction stoves. Furnace to electric heating. From ice boxes to refrigerators. From high ceilings to AC units. From books to TVs and then to TVs in every room. Compute hardware wise most people are using probably 5% of their cpu to web browse.

Once we hit the 90s, what are even the sources for added consumption in American households? We hit all the big ticket power sucking items already, like refrigeration and AC.

If zsh has its completion fully configured by default, there will be no need for most people to turn knobs nor will it be a "half decent shell." It'll be the best shell, if it isn't already.

I wonder why ghost text history suggestions are popular though, I'd rather not have it. Shell history search works better, and I don't want my shell always showing me or whoever else is looking at the screen random commands that I've previously typed.

They claim 75% better. I doubt this is better than compressors in general but they seem to be going for a niche where a high power compressor does the high load part but when only a litte cooling is needed the compressor is now very inefficient and so the peltier is better. Normal fridges just let the temperature have a wider swing which is good enough for most needs.

> In a way, this is being done. If you look around a little you'll see a bunch of jobs that pay like $50+/hr for anyone with a hard science degree to answer questions. This is one of the ways they're collecting data and trying to create new data.

This is what expert systems did, and why they fell apart. The cost of doing this, ongoing, forever never justified the results. It likely still would not even at minimum wage, and maybe more so because LLM's require so much more data.

> All these problems should be assumed to be within the training data.

And yet most models are going to fall flat on their face with these. "In the data" isnt enough for it to make the leaps to a solution.

The reality is that "language" is just a representation of knowledge. The idea that we're going to gather enough examples and jump to intelligence is a mighty large assumption. I dont see an underlying commutative property at work in any of the LLM's we have today. The sooner we get to an understand that there is no (a)I coming, the sooner we can get down to building out LLM's to their full (if limited) potential.

> But then I remind myself: it’s not a product made for me. I don’t have to like it.

That’s not the point of the article, though.

It never says it’s not a good product. The issue is not that, it’s that it is a disposable product : the day the company behind it closes or decides to unplug the wires, the toniebox instantly becomes a paperweight.

That’s at least an ecological issue, but also a moral issue. I think it’s wrong in 2025 to give objects to our kids that we know have no future.

Disclaimer : someone offered a toniebox to my son so we own one. I agree it’s a good product.

But there was an opportunity to make it working fully offline and they decided not to for money reasons. The figurines could have had some mb of embedded memory, it’s not like they were cheap to buy.

This guy had a green card and no past crimes. They're also deporting refugees that are here under protection. What they're doing is lawless and immoral.

I'm 100% for deporting people that have overstayed their visas and are working. They are workers without labor protections and essentially slave labor and when they get hurt on the job their medical bills are payed by you. (In this case the government should make those that were supporting them pay their medical bills)

Transaction fees are lower because no one really uses the L1 network for commerce anymore. It goes back to the 2017 block size war.

>Besides that, there are other cryptocurrencies (Solana? Stellar?) which have effectively zero fees and are much faster than Bitcoin.

They are faster because they are not very decentralized. The entry costs for vendors to independently audit and verify payments the blockchain is greater.
Ask HN: How to get portfolio exposure to RISC-V?
by micvbang | 2025-07-20 21:02:19+00:00
I believe RISC-V hardware is going to well in the coming decade. I've been trying to figure out what I can invest in to get exposed to it, but have been unable to find anything with direct exposure but privately held companies, e.g. SiFive. I'm happy to hear about indirect exposure as well, but I've already got the most obvious cases like e.g. TSMC on my list.

Do you have any ideas for how to get exposure to RISC-V hardware?

Maybe OP doesn't literally think amazon had to convince some people to not eat beef to get the datacenter built, but it's pretty obvious that the underlying sentiment of "we're making sacrifices so amazon can build a datacenter" is sincere. But that doesn't make much sense either, because the two things (ie. guy eating beef, amazon build datacenter) is totally unrelated. Doing one isn't enabling or preventing the other.

The browser platform with HTML/CSS is fundamently legacy over legacy and broken for most application styles ( not general pages ), and incurs insane development costs for even simple things ( been there done that for close to 17 years )

The current best option IMO is: Open Full Browser window size canvas (with webgl, webgpu backend graphics ) and draw everyhing yourself ( meaning with something else than the browser layout engine, lots of options available, Flutter, Avalonia etc... ) and deploy with your favourite programming language through WASM.

In fact a next generation browser should bascially be this, with the legacy browser functionality implemented as a WASM module that draws to this single canvas... The browser would become small and much easiert to secure ( only input, audio and general WASI style apis missing and to secure )

Unless you're about to fix hallucination, isn't it more harmful to have AI administer inaccurate information instead?

Refusing to answer lobotomy-related questions is hardly going to prevent human harm. If you were a doctor trying to research history or a nurse triaging a patient then misinformation or neglected training data could be even more disastrous. Why would consumers pay for a neutered product like that?

Not sure if it's appropriate to post ChatGPT's response here, but I gave the same challenge to o3 and it's response was:

``` 2025-07-20 10:32 That’s an exhilarating challenge! But here’s the sober reality:

*1. Scale & Surface Area*

* *Jira* and *GitLab* each represent well over a decade of engineering effort from dozens‑to‑hundreds of developers, QA, designers, product managers, and SREs. * They’re not just web apps—they’re ecosystems: issue tracking, CI/CD pipelines, permissions, integrations, APIs, marketplace extensions, mobile clients, high‑availability clustering, compliance tooling, analytics, and elaborate permission models.

*2. Engineering Effort in One Week* Even an aggressive “strip‑to‑core‑features” build would demand:

| Area | Must‑Have Functionality | Typical Complexity | Realistic Time (solo) | | ---------------------------- | ------------------------------- | ------------------ | --------------------- | | Auth & user management | SSO, 2FA, roles | weeks | 3‑4 weeks | | Issue / Merge request model | CRUD, workflow, attachments | months | 4‑6 weeks | | Git backend or sprint boards | Repo storage or board drag‑drop | months‑years | 8‑12 weeks | | CI runner orchestration | Job scheduler, logs, artifacts | years | 6‑12 months | | Notifications & webhooks | Email, Slack, webhooks | weeks | 3‑4 weeks | | Security & compliance | RBAC, audits, CVE patching | ongoing | Ongoing |

That’s after *scope‑cutting to the bone*—and still well beyond seven days for even a seasoned full‑stack team.

*3. Minimum Viable “Clone”* If the goal is a demo that looks Jira‑ or GitLab‑like and handles the absolute basics (login, create issue, simple Kanban board or Git repo viewer), you’d still need:

* *Pre‑built OSS components* (e.g., Focalboard, Gitea, Drone CI) * *Glue code* to stitch UI, auth, and database models * *DevOps* for cloud deploy, backups, SSL, monitoring * *Acceptance tests* so the demo doesn’t fall over during the pitch

With a well‑coordinated *5‑7 person tiger team*, an MVP façade might be shown inside a week—but it would be fragile, feature‑poor, and nowhere near production‑ready.

*4. What \$1 million can buy fast*

* *Fork & skin* an existing open‑source platform (e.g., Forgejo for GitLab‑like, OpenProject or Plane for Jira‑like). * Hire a *dedicated squad* (engineers, designer, DevOps) on a 3‑to‑6‑month crash program to reach parity for the specific subset of features you actually need. * Budget for *security audit, uptime SLA, and ongoing maintenance*—because the first release is only the beginning.

*5. Suggested Next Steps*

1. *Clarify scope:* Which exact capabilities do you really need on Day 1? 2. *Select a foundation:* OSS codebase vs. greenfield build. 3. *Form a team + timeline:* Realistically 12–24 weeks for a hardened v1 with a mid‑sized team. 4. *Milestones & deliverables:* Demo, beta, public launch, enterprise tier. 5. *Contingency planning:* Budget for security, scaling, and feature creep.

If you’d like, I can help map out a detailed project plan, assemble a tech‑stack recommendation, or break down resourcing and costs. Let me know how you’d like to proceed! ```

As long as we're stuck in the type of secrecy Einstein so objected to, nudging ecosystems back to within sustainable margins using geoengineering will be way too risky anyway. However, should a situation arise where such a worldwide orchestrated attempt becomes plausible, we'll need as much data as possible if projections are to match the actual outcome of our meddling... If too much data has gone missing (or has become unreliable as a result of being tampered with), this approach will no longer be an option at all.

OK, a typical Peltier device has 3.5% coefficient of performance, that is, it produces 35 W of cooling per 1 kW consumed.

Fine, let's expect that the new tech doubles the efficiency, to 7%. Still, to my mind, pretty wasteful, on par with a steam railway engine. A Peltier element is good in cases where you can afford a large heat removal device, but need precise temperature control and no moving parts. For a home fridge, I'll take the sound of the compressor and the temperature fluctuations of a 400% efficient compressor-based heat pump over a Peltier element any day.
