Lots of people dislike change. Neophobia is a thing, and it's not particularly uncommon.

The good news is, they'll rapidly adapt to each new solar farm; the bad news is, they'll forget about all the ones they're used to by the time comes to expand — I've seen anecdotes of the same thing happening with power lines, where people were upset that some proposed new ones would ruin the view, the person proposing them said they wouldn't be any different from the current ones, and the complainers said "what current ones?" and had to have them pointed out.

> Learn the classic tools, learn them well, and your life will be much easier.

Agreed, but that doesn't stop you from using/learning alternatives. Just use your preferred option, based on what's available. I realise this could be too much to apply to something like a programming language (despite this, many of us know more than one) or a graphics application, but for something like a pager, it should be trivial to switch back and forth.
Show HN: Manage App Store Connect the Smart, Automated Way
by selcukcihan | 2025-10-13 11:56:51+00:00
We are building a powerful CLI tool for managing apps on App Store Connect. It will manage in-app purchases, subscriptions, pricing, and more with IaC (JSON-based configuration). By transforming hours of manual work into minutes of automation, we hope it will particularly be useful for indie developers.

Today is our launch day on Product Hunt, we are collecting a waiting list if you are interested https://www.producthunt.com/products/storeconfig

Wow, that looks fun and probably get to learn a lot about algorithms.

I don't have any feedback, but rather a question, as I've seen many repositories with people sharing their algorithms, at least on GitHub for many different languages (e.g. https://github.com/TheAlgorithms), what did you find that was missing from those repositories that you wanted to write a book and implement hundreds of algorithms, what did you find that was lacking?

People must get taught math terribly if they think "I don't need to worry about piles of abstract math to understand a rotation, all I have to do is think about what happens to the XYZ axes under the matrix rotation". That is what you should learn in the math class!

Anyone who has taken linear algebra should know that (1) a rotation is a linear operation, (2) the result of a linear operation is calculated with matrix multiplication, (3) the result of a matrix multiplication is determined by what it does to the standard basis vectors, the results of which form the columns of the matrix.

This guy makes it sound like he had to come up with these concepts from scratch, and it's some sort of pure visual genius rather than math. But... it's just math.

This is totally an aside, but I wonder how long the "Swiss army knife" metaphor will hang on in popular culture. People generally use it to indicate that something does a variety of things, but I'd say many of younger generation have never touched if even seen such a knife in their life, and even among older generations it doesn't have a positive connotation.

Like when I hear something is the Swiss army knife of something, my take is that it does a lot of things poorly and there are better specific tools for every need. Like if you need a really terrible knife or bottle opener or screwdriver or saw, a Swiss Army knife has you covered. But it should be a tool of last resort when you have no other options.

>A warlike country with a history of antagonism to China is probably less secure than countries that have chosen to behave like good neighbors.

That is naive. China will become imperialistic if given a chance. Look at how they treat their neighbors.

>If you feel like panel production is strategic

I don't necessarily. But many strategically important things suffer the same fate. We cannot compete with China and other low-wage countries without restructuring the monetary system and probably our lifestyles. The Chinese know this and have used the situation to hoover up production capacity for many things that are critical to national security.

>US has a substantial ability to produce panels [1], perhaps a useful strategy would be to consume those panels as much as possible, subsidizing production to make it a growth area.

It would make far more sense to simply ban the import of cheaper panels, and let those who need the panels pay the true cost. The reason is that you could apply the same logic to every offshore-made item, and these subsidies would make random people pay for stuff that random other people are using.

>I'm no economist but the above seems like a solid strategy to me. It would be most interesting to see the outcomes where a country pursued this strategy versus one that actively worked to marginalize solar, killing domestic production instead.

I don't think anyone is trying to kill their domestic solar industry in general. But these installations have to be justified somehow. If the domestic panels are not the cheapest/best option available, they won't be used.

> that if you ever change your OS installation

apt-get/pacman/dnf/brew install <everything that you need>

You'll need install those and other tools (your favorite browser, you favorite text editor, etc) anyway if you're changing your OS.

> or SSH anywhere

When you connect through SSH you don't have GUI and that's not a reason for avoiding using GUI tools, for example.

> even use a mix of these on my personal computer and the traditional ones elsewhere

I can't see the problem, really. I use some of those tools and they are convenient, but it doesn't matter that I can't work without that. For example, bat: it doesn't replace cat, it only outputs data with syntax highlight, makes my life easier but if I don't have it, ok.

Some places have free RTK networks their citizens can use. Michigan's department of transportation, for instance, runs a CORS network that anyone can request access to. (At least as far as I can tell. The signup form doesn't ask for affiliation or payment.) It's just distributed over the internet, the assumption being that you probably have internet access already.

One of these days I'll figure out how to set up a free NTRIP caster on my Galmon station so it can do double-duty. The trick then is advertising and discovery.

It would be lovely to have, say, a standard wifi SSID or a standard LORA channel that your local corrections network would broadcast on. That way you could have a large number of client devices not each needing their own internet access SIM card or whatever. I wonder if the corrections stream would fit into an FM RDS payload or something.

Trouble is, there's so much money in the L-band corrections services, and so little money in replacing them for free...

Oh, yeah, the cryptocurrency folks have weighed in, there's a thing called "goodnet" which appears to be microtransactions in exchange for NTRIP streams over some medium. I haven't looked further into it.

Under the "How difficult is it to exploit" in the FAQ they mention it's very easy and with 100% success. Yet the text itself says this:

In our analysis of the RMP initialization, we observed that the malicious hypervisor running on the x86 cores can still create dirty cachelines pointing to DRAM. [...] As depicted in (c), the malicious hypervisor can use the primitive to get arbitrary unchecked writes to RMP memory.

So it would seem it's easy as long as you managed to install a malicious hypervisor...

Of course not great, with supply chain attacks being a serious cause for concern. Still, hardly "easy" if it requires hijacking a core piece of infrastructure?

I shall quote:

“ The right of workers to manage the state, the military, various enterprises, and cultural and educational affairs is, in fact, the greatest and most fundamental right of workers under the socialist system. Without this right, other rights of workers—such as the right to work, the right to rest, and the right to education—cannot be guaranteed. … We must not understand the issue of the people's rights as meaning that the state is managed only by a small group of people, while the rest of the people merely enjoy rights such as labor, education, and social security under their management.”

Unless it gets outlawed, which I suspect is something Trump might do or attempt as part of his campaign in favour of fossil fuels and/or to own the libs/China.

I'm also not clear how cheaply the US could make its own PV in the event of arbitrary trade war (let alone hot war) between the USA and China.

(The good news there is that even in such a situation, everyone else in the world can continue to electrify with the panels, inverters, and batteries that the USA doesn't buy, but the linked article obviously isn't about that).
by js8 | 2025-10-13 12:01:22+00:00
Yeah. That's why I am saying it's the epistemological problem.

In the above example, that NN recognizes rose as a rose is an assumption that it is correct as a model of the (part of the) world. On that assumption, we get a formal definition of "an image of a rose in the pixelated image", and we use that to formally prove our system allows roses to be painted.

But getting rid of that assumption is I believe epistemologically impossible; you have to assume some other correspondence with reality.

I agree with you on the hardware. I think the biggest obstacle to software formal correctness is the lack of formal models of which we can be confident describe our environment. (One obstacle is the IP laws - companies do not like to share the models of things they produce.)

Show HN: ChartPilot now tracks the top US MidCap and 300 stocks hourly
by thisisagooddayg | 2025-10-13 12:01:46+00:00
Last week I shared an early version of ChartPilot.

Since then I’ve rebuilt a big part of the backend (FastAPI + PostgreSQL + Polygon) and added a new collection: US MidCap 100.

The scanner now checks 300+ stocks and ETFs across 1h, 4h, 1d and 1w timeframes every hour, combining EMA 10/55/200, ADX, RSI and Squeeze Momentum to flag trends before they expand. It’s free to explore here

Would love feedback on performance and how useful multi-timeframe signals are for your trading workflow.

Sorry, I've reread this a few times and I'm not sure which part of Searle's argument you think I mischaracterized. Could you clarify? For emphasis:

> "consciousness can't be instantiated purely in language" (mine)

> "we cannot get from syntactical to the semantic just by having the syntactical operations and nothing else" (Searle)

I get that the mapping isn't 1:1 but if you think the loss of precision is significant, I'd like to know where.

> Unfortunately, it doesn't seem to me to have proven anything; it's merely made an accurate analogy for how a computer works. So, if "semantics" and "understanding" can live in <processor, program, state> tuples, then the Chinese Room as a system can have semantics and understanding, as can computers; and if "semantics" and "understanding" cannot live in <processor, program, state> tuples, then neither the Chinese Room nor computers can have understanding.

There's a lot of debate on this point elsewhere in the thread, but Searle's response to this particular objection is here: https://plato.stanford.edu/entries/chinese-room/#SystRepl

duf is pretty good for drive space, has some nice colours and graphs. But its also not as useful for feeding into other tools.

btop has been pretty good for watching a machine to get an overview of everything going on, the latest version has cleaned up how the lazy CPU process listing works.

zoxide is good for cding around the system to the same places. It remembers directories so you avoid typing full paths.

I see, it makes sense. But I feel like it is a worth while compromise.

Attestation as I understand it is to allow third parties to trust a user's computing device for purposes of handling their sensitive data (both from the user's and the third party's point of view) in a way that doesn't rely strictly on the user's savvy for keeping everything leak proof.

Even if this data belongs to me - as said user - I still think that the existence of open source attested software is a net benefit in the bigger picture because the future looks more and more dependent on secure computation.

Working on https://fileboost.dev –– A Ruby on Rails Active Storage plugin that is a plug and play gem for image transformation without making any code changes.

Being a Ruby on Rails consultant, I frequently see active storage transformation becoming a bottleneck for web servers by eating up resources and making them sweat.

I built Fileboost to solve this problem for my customers. I'd love any feedback.

Killing Reader didn't just kill Reader. It killed the expectation of RSS to be a valid default consumption format of the internet. These days, if you use RSS, it's either relying on some legacy hidden feed feature that hasn't been shuttered yet (lots of Rails and WordPress sites that are like this) or you're explicitly adding RSS to your site as a statement.

Picking up the pieces after Reader was impossible because the entire RSS ecosystem imploded with it. Almost every single news site decided that with killing Reader, they wouldn't bother maintaining their RSS feeds, leaving them basically all "legacy" until they irrevocably break one day and then get shut down for not wanting to get maintained.

> bat it's a useless cat. Cat concatenates files. ANSI colour breaks that.

It's useless as a cat replacement, I agree. The article really shouldn't call it that, although the program's GitHub page does self-describe it as "a cat clone". It's more of a syntax highlighter combined with a git diff viewer (I do have an issue with that; it should be two separate programs, not one).
Show HN: Universal MCP gateway for AI agents
by mcp360 | 2025-10-13 12:04:49+00:00
Hey HN Community,

I built MCP360 after spending weeks integrating APIs for an AI agent project. Each tool needed its own setup, auth, billing, and maintenance. When any APIs changed, my integrations broke. I got tired of it.

MCP360 is a single gateway giving AI agents access to 100+ tools through one config block. Search engines, web scraping, SEO, e-commerce data, maps, domain tools, and more.

Real example: Instead of managing Google Search, web scraping, SERP tracking, and keyword research as 4 separate subscriptions (4 bills, 4 auth systems, 4 points of failure), you connect once.

Works with Claude Desktop, Cline, or any MCP-compatible client.

Setup in 2 minutes: - Copy one config block into your MCP client - Start using 100+ tools immediately - We handle everything for you

There's a free tier to get started.

I'm posting here because I need feedback from people building real agents:

1. What integrations are you currently struggling with? 2. What would make this genuinely useful (not just convenient)? 3.What tools should we add next?

This is early stage. I'm building based on what people actually need, not what sounds cool. Honest feedback welcome, even if it's "this doesn't solve my problem because X."

Website: https://mcp360.ai

Happy to answer technical questions!

Problem: Trailing commas, key-quoting-rules, etc are a problem when generating JSON from scripts/templates - which is a key practical necessity for a Configuration language. Of course, you may already disagree here and say you don't have this problem, but it's a sufficient problem for everyone that there are many attempts to solve it. If you don't have this problem, feel free to ignore.

MAML: Takes JSON, makes trailing commas & key-quoting optional. One may not like it, but it does indeed solve the scripting problem, and it's a nice and novel idea. Thereby it's a "Superset" of JSON. All JSON is valid MAML, but all MAML is not valid JSON.

JSONNet: Also a good attempt, directly solving the scripting problem with built-in functions and so on. But can be overwhelming.

Other approach: A strict "Subset" of JSON. Every value MUST end with a comma, whether it's first or last. Every key MUST be quoted. Comments MUST be a valid JSON key-value called ".comment" that will be ignored at parsing but otherwise part of the JSON. JSON5 seems to be more suitable for this.

updates on learnings - the feed back from hn about ground truths was helpful passed this thread into the ai and it started to base truth on exa search. - it produced alot of slop so it added a review cycle to remove alot of the slop. - it worked out it was doing performative work then removed the data as code and moved this to toml. it then started to focus heavy on processes and doing things like the ALDH2 metabolic process.

honest take - decent at getting a quick understanding of what the ALDH2 process is like but struggles with harder modelling, the experiment gave better insights into ai then medical. (slop is countable with exa mcp (ground truthing, research, anti hallucinations).

There are some attempts at things like this: https://www.opensourceecology.org/gvcs

They're usually very hard to get share because machine manufacturers can smash out cheaper things via processes like castings, mouldings and stampings, then eventually lock down spares (or just don't bother).

The open source option basically only be worse (but maybe more repairable) and/or more expensive than the alternatives, except when there is no alternative in the market. And China is providing so much mid-grade affordable and fairly functional stuff there often is an alternative even in the most isolated places. In 1980, getting a decent lathe in some town in, say, Angola might have been basically impossible. Now, it's still not cheap, but it's not completely impractical. If you can get bearings and induction-hardened shafts you'd need to DIY, you can get the whole thing, and maybe even cheaper.

It's a bit depressing, because of course I want to see the world flooded with high-quality, modular, very standardised, re-usable, repairable, hackable items, but that approach has a limited market in reality.
by kcexn | 2025-10-13 12:06:13+00:00
It's a little bit more complicated than that if you were running a business.

You would want to add the cost of your network+hardware depreciating over the timeframe, and you probably can't just ignore the first 185W since if you are Anthropic it doesn't seem likely that the idle power draw would be needed if they weren't expecting to serve AI traffic.

So, let's say $0.02 per hour ($1/50 roughly). That's about $15 per month per user. Let's call it $10 per month per user since users aren't constantly hammering the service. To support a big sales and marketing engine, you would like to be selling subscriptions for $100+ per month. I'm just not sure people are prepared to pay that for AI in its current form.

>A "simulation" is, by definition, simply an accounting game by which a series of descriptive statements can be derived from some others -- which necessarily, lacks the causal relations of what is being described.

This notion of causality is interesting. When a human claims that he is conscious, there a causal chain from the fact that they are conscious to their claiming so. When a neuron-level simulation of a human claims it is conscious, there must be a similar causal chain, with a similar fact at its origin.

I spent about 30s on those options, but ok, I'll bite.

> Google it and start trying random suggestions.

If the options were indeed as I suggested, why would the top Google result not say "click the very clearly labelled 'scan missing photos' button"?

Google search results are useless when tech companies don't empower users with clear control over their data. Users are reduced to superstitious peasants not because that's their nature, but because they are not given the capability to act otherwise.

No, that's not the message it sends at all. It says: what's in the contracts matter. NL - and in consult with a lot of other countries that have a stake in this - gave conditional permission for this deal. That allowed the Chinese company to take effective control while still protecting the various interests in the IP and in the continuity of the company. NXP is not just a fab, it is much more than that and as such it is critical infrastructure for a large swath of EU and US industry. That's why I believe the sale was a mistake, but I can see how if the counterparty promises to abide by certain restrictions that they let the deal go through. What happened now is a direct result of activity related to bypassing those restrictions.

The fact that this is a mechanism that has been only extremely reluctantly used is proof positive that NL is open for business, and I'm pretty sure this will have immediate consequences for further acquisitions of EU tech by Chinese companies.

Swiss Army knives seem to be as popular as ever. What do you mean, doesn't have a positive connotation?

They're great hiking, camping, traveling, in backpacks and bags.

What's wrong with it as a knife? It's perfectly sharp. Obviously it's not a full-sized chef's knife, but it will cut your apple or twine or packing tape. It's a multitool. It does lots of things. A tool of "last resort" seems to miss the point -- it's not meant to use at home, when you have a full-size screwdriver and bottle opener and corkscrew. It's for traveling with you. And it's great at that.

SAK's are iconic. I don't think your take is a common one.
