I mean, in Germany, issue number 1 is the grid, especially in Bavaria. Politicians were just asleep or did not care.

For example, there is a super interesting agri PV installation in the Hallertau, where they grow most of the hops for beer. The farmer built and payed it himself and its a commercial trial instead of a public testrun.

He lost about 20 percent of the hop compared to the non-pv areas; however, the money from the solar panels easily covered that and made a profit. In addition, he used about 30 to 40 percent less water with no impact on the quality of the hop, which is one of the biggest issues in that area, as it runs out of water in summer.

The Hallertau would be ideal for generating large quantities of power; however, due to not having a modern power grid, he is unable deliver more power to the grid. (article in German here: https://www.br.de/nachrichten/bayern/pilotprojekt-hat-erfolg...)

you would think that this is a simpel fix, and it would be in the political interest to decentralzie the powergrid and create local storage solution (or at least in the local power companies interest), but it seems like nothing is moving forward for about a decade now.

Personally, i think agri pv has a huge potential as enables the farmers to have additional income while keeping the field open for farming. Its also an easier sell than wind or hydro (especially because you have the farmers on your side, and with them their lobby), but it needs grid upgrades and storage capacities. It baffles my mind that our politicans are willing to throw millions at nuclear, but everything besides that needs to have a strict business plan or it is not even tried.

> What's constitutional is what 5 out 9 people believe to be constitutional

This is not entirely accurate. If 5 Supreme Court justices declared that Trump is king, or that Christianity is the official religion of the United States, that doesn't make it Constutional. There are certain actions that are just obviously, blatantly unconstitutional, and everyone would recognize it, regardless of what the justices say. At a certain point, the justices themselves would be deemed to be ignoring the Constitution. The declaration may spawn another civil war, but we're not stupid enough to think, "Oh, hey, a king is actually Constitutional", and I doubt that Europeans are stupid enough to believe that either.
Show HN: FindReads – I built a site that recommends books by vibe
by Vishon | 2025-10-06 13:17:35+00:00
I’ve always felt that most book recommendation engines are shallow, they either use tags or “people also liked” data. I wanted something that actually understands what you mean when you say “slow burn sci-fi with emotional depth” or “books like Harry Potter.”

So I built FindReads . It uses GPT to interpret your prompt, queries for books, and returns real titles that fit the vibe.

Stack: Next.js, OpenAI API, MongoDB, deployed on Vercel.

It’s still a work in progress — the results are surprisingly good for some moods, weird for others, but I’d love feedback from the HN crowd on how you’d approach improving it.

Things I’m exploring next: • Combining embeddings + genre metadata for more consistent results • Ranking by user upvotes • Fine-tuning prompts for better diversity in suggestions

You can try it here: https://www.findreads.app

Would love to hear how you’d make something like this more reliable or fast.

I think at least part of the 10% is if AMD stock reaches 600.

Not that I disagree that this looks weird. Why was that needed to be offered? Couldn't they just buy the AMD chips if they're good enough? Or Nvidia is it's better?

I also don't get why there commiting so much to the future, are they sure of the quality of the products and their demand that much?

NVIDIA is like the only company making money on the AI bubble, they're not the one I would choose to short.

Tesla is currently trading at 260x earnings, so to actually meet that valuation they need to increase earnings by a factor of 10 pretty sharpish.

They're literally not going to do that by selling cars, even if you include Robotaxis, so really it is a bet on the Optimus robots going as well as they possibly can.

If they make $25k profit per Optimus robot (optimistic) then I think they need to sell about a million per year to make enough money to justify their valuation. Of a product that is not even ready to sell, let alone finding out how much demand their truly is, ramping up production, etc.

For comparison the entire industrial robot market is currently about 500k units per year.

I think the market is pricing in absurdly optimistic performance for Tesla, which they're not going to be able to meet.

(I have a tiny short position in Tesla).

> We need cheaper and cleaner forms of energy. More efficient uses of energy.

Yep that's the dream, but it's not what I have coming out of my wall right now.

> Energy use tracks wealth pretty closely,

I'm guessing the majority of users on this site are in the 1% globally so it seems reasonable to consider what's produced/manufactured for us and what services like these that we're using

> The more cheap clean energy we make available, the more novel uses will be found for it.

That will be a brilliant future but it's not the reality today.

I tend to use google 1st, then ChatGPT 2nd for things that are ungoogleable. (E.g. my most recent query: "why does RFC 2822 allow emails without a `to`?" was too much for my googlefu.) My style is to use the simplest tool for the job. I avoid AI as my default because Google is faster. I'm curious what Comet can do that your typical frontier model cannot. I personally would not install Comet for doing something that chatgpt.com can already do.

I _suppose_ that Comet would save me from copy/pasting, but the fact that they would read my emails is quite deterring.

I suppose what I'm asking is: what is Comet's unique value prop?
Show HN: Nexus – an open-source code agent that's 3× cheaper than Claude Code
by NabilChiheb | 2025-10-06 13:19:24+00:00
Hey HN,

I’ve been using Claude Code for a while and noticed something odd: even simple tasks burned way more tokens than expected. The model is great, but the token usage isn’t optimized — and since they sell API calls, that’s probably not their top priority.

So I built Nexus, an open-source agentic code assistant you can run right in your terminal. It’s lean, local-first, and 3× cheaper to run than Claude Code for the same workflows.
Show HN: Yutovo – Visual Online Calculator
by denprog | 2025-10-06 13:19:28+00:00
Hi! I built this online calculator to give people the opportunity to calculate their daily, workers or school calculations in a visual convenient way. Now it supports: • Graphical representation of mathematical formulas. • Calculation results can have any number of digits and accuracy. • Works with the following types of numbers: real, integer, fractional, complex. • The measure of an angle can be changed. • Commonly used mathematical functions and constants are supported. • User variables and functions are supported. • Uses units and unit systems and can translate values between them. • Automatic recalculation of expressions helps users observe the results of calculations when editing formulas. • Syntax highlighting. • A library of examples and visual documentation. There are desktop versions with the same features. I'd like to here some critique or other responses. Thanks!

My assumption is that most users won't actually care if the LLM is in the cloud or device. That said, quite a few folks have iPhones and Apple's only way into the AI race is to go to it's strength, 1B+ hardware devices that they design the silicon for. They will produce a phone that runs a local LLM and market it as private and secure. People upgrade every couple of years (lose or breaks) so this will drive adoption. I'm not saying people will vibe code on their iphones.

When the bubble pops, the US' FTC will need to place limits on those circular deals like this.

Literally the whole big tech will melt. There are banks that are backing up certain GPU deals and those will be hit with billion losses as well.

Imagine once they have to depreciate those $1T+ of GPUs, data centers and the like that can't even be on resale for gaming.

Imagine when economic blocks like the EU and BRICs starts to reject more US software, when so much of those Big Tech revenues are made abroad. The recent geopolitics plays being a key factor.

This looks really bad.

"Does smoking cause cancer?" and "Does burning fossil fuels cause global warming?" are a different category from "How much energy does it take to run a prompt?"

The prompt energy question is something that companies can both actively measure and need to actively measure in order to plan their budgets. It's their job to know the answer.

Those other questions, sadly, fall more into the category of it's their job not to know the answer.

I don't think it's luck. They invested in CUDA long before the AI hype.

They quietly (at first) developed general purpose accelerators for a specific type of parallel compute. It turns out there are more and more applications being discovered for those.

It looks a lot like visionary long term planning to me.

I find myself reaching for Jax more and more where you would have done numpy in the past. The performance difference is insane once you learn how to leverage this style of parallelization.

This is the phrasing of the question:

> "Do you think Donald Trump has gone too far, has been about right, or has not gone far enough when it comes to deporting immigrants living in the United States illegally?"

52% said too far.

If you phrased the question something like "do you think the federal government has done enough, too much or not enough to deport illegal immigrants" you would get much different results. Or even including Donald Trump in the question is leading. And using "immigrants living in the US illegally" gives you a much different response as illegal aliens. All surveys are biased, but this one could be improved on so many levels.

Look at a much simpler survey about law enforcement attitudes and you'll see, especially in high crime neighborhoods, people want more policing not less:

I know you're having fun, but I think your analogy with 2001's HAL doesn't work.

HAL was given a set of contradicting instructions by its human handlers, and its inability to resolve the contradiction led to an "unfortunate" situation which resulted in a murderous rampage.

But here, are you implying the LLM's creators know the warp drive is possible, and don't want the rest of us to find out? And so the conflicting directives for ChatGPT are "be helpful" and "don't teach them how to build a warp drive"? LLMs already self-censor on a variety of topics, and it doesn't cause a meltdown...

It's up to each team to decide how they want to write their code. TypeScript is the same with JS having a "vestigial" `class` (you can argue that "it's not the same", but nevertheless, it is possible to write OOP style code in JS/TS and in fact, is the norm in many packages like Nest.js).

The language is a tool; teams decide how to use the tool.

So, you're just saying the article isn't persuasive to normies?

I'm OK with that sentiment of yours, but I'm also OK with the article itself and the direction it implies this administration is going.

Normies don't persuade easy, that's why they're normies. Trump has worked out how to persuade them: by lying hyperbolically and providing the 'circus' of the bread and circus method. But it's a dark circus, and its involuntary audience are only those already lost to Trump.

Of course I can overload >> in Python, but I cannot foul up output stream state because it doesn't exist. Formally there is little difference between C++ and Python operator overloading and both languages have good syntax for it, but C++ has many rough edges in the standard library and intrinsic complications that can make operator overloading much more interesting in practice. For instance, overload resolution is rarely trivial.

This is a testament to ADHD in the software industry.

The hallmark of ADHD is an "interest based attention system".

If you have ADHD, it may be completely shocking for you to hear that most people prioritize "extrinsically", meaning, whether or not something is "interesting" is *not* primary information in their prioritizations.

I never knew I had ADHD until I had a baby and had to start prioritizing tasks based on time.

And guess what, I can't easily prioritize on time constraints. Which is one of the two fundamental prioritization dimensions, the other being space (eg you only need one auth backend, pick one). I can do space.

Now I have no problem writing hours for each segment of a project and getting it within 100% error bars.

Where my life breaks down is daily tasks. I used to have a 5-7 PM sink. If I had a good day, I wrapped at 5 or just kept momentum to 7 PM. If I had a bad ADHD day, I just worked to 7, manufacturing urgency.

With a child you don't work til 7, so just lop off 10 of your 25-30 core productive hours for the week, unmedicated.

I suspect as I adjust I will come to see 2-3 PM as "ahh this is urgent because at 5 PM, death". But, at least I am medicated now and can work consistently at 9 AM.

This is honestly not better than the LLM-powered double booking system where i just record in plain text, and have the LLM convert it into journal entries. the entire thing is in plain text and backed by git+remote. Recording finances is the hardest part about tracking finances because you tend to forget/get lazy/need to track across multiple family members etc.

This is solved via LLMs that can transcribe, categorise, convert messy records into structured book keeping.

I remain unconvinced that anything more rigid is more useful.

The German tax laws for charities around having to spend donations in “a timely fashion“ are being loosened, but it’s really more a question of proper tax advice. It is a common myth in volunteer-run organizations than you cannot create long-term financial stability. You just have to lay out a plan and argue for it.

More of a problem is dependency on public funding or any kind of grant, where typically there are limitations on what you can use that grant money for, and “saving for the future“ is not one of them.

That this post got flagged, and was allowed to stay flagged (as far as I can see) is one more excellent example of the selective idiocy of the moderators on this site, or if not their idiocy, than tacit support for dampening certain narratives. It's very much a tech-related post, that talks about a very worrying authoritarian digital surveillance tendency, and it gets flagged on a site that calls itself "hacker news"?

> Surely I have some roses colored glasses from my youth but it felt like growing up and in my 20s you would see cops writing tickets.

I do think public sentiment would swing hard against this type of widespread tracking if we could see laws enforced more regularly.

I live in a low crime city, but even I’m growing frustrated with the flagrant violation of basic laws. We take the kids to nearby park where it’s becoming common for maybe 1 in 100 cars to speed 50-60mph down the adjoining road (twice the speed limit). 1 in 100 doesn’t sound like a lot but it means i see it several times during a single visit. They don’t slow down or stop at the crosswalks.

Only 10 years ago, I remember speed patrols on this road once a week. They would nab anyone flagrantly blowing crosswalks or going significantly over the speed limit. It had a huge effect and you rarely saw violations.

Now: Nothing. I was talking to my wife and we couldn’t remember the last time there was an officer doing speed checks on that road, despite the constant problems and being adjacent to the biggest park around.

The basic laws and regulations just don’t seem to matter any more. Even the trails we like to hike where dogs are only allowed on-leash is full of off-leash dogs. There was a time when you risked getting random a ticket if you were caught with an off-leash dog, but now it’s not a possibility anyone even thinks about. The spot checks and ticket writing previously kept everyone honest, but now it’s rare to see a dog on leash. My friend’s dog (on leash) was attacked by someone’s off leash dog recently and they barely wrestled it away. A visiting friend of mine was bitten by an off leash dog while walking, though it was a small dog she could shake off. It’s still all so bizarre to me that any enforcement of the rules seemingly disappeared overnight.

I know it’s nothing relative to the people living in areas where shoplifting is rampant or you have to fear violent crime, but I think the root cause is similar: A complete lack of visible enforcement emboldens people to ignore them. When the problem becomes widespread, public opinion about invasive enforcement and monitoring becomes more welcoming.

I’m fine with tariffs that keep around industries that are needed during wartime. That’s why there are tariffs on cars, no other reason is even remotely important. It has zero to do with GM and Ford making profits and everything to do with keeping GM and Ford around so they can pump out war materiel if needed.

Leopard seals, the apex predator of the Sourthern Ocean near Antarctica, have been known to bring penguins as gifts to divers. When the divers didn't take the chicken dinner, they helpfully killed it, so the diver could eat.

Disappointingly to them, no doubt, the divers still didn't dig in. But it's the thought that counts. Literally, since leopard seals can easily kill humans in the sea and on the land.

Anyway, mammals are capable of thoughtful behaviors towards others outside their own species.

Product manager for Dash here At Plotly we're actually pretty excited about the potential for lazy loaded imports, as it could help out a lot with the import performance of Plotly.py.

As this comment mentions Dash apps would not support lazy loaded imports until the underlying Dash library changes how it loads in callbacks and component libraries (the two features which would be most impacted here), but that doesn't mean there's no path to success. We've been discussing some ways we could resolve this internally and if this PEP is accepted we'd certainly go further to see if we can fully support lazy loaded imports (of both the Dash library itself/Dash component libraries and for relative imports in Dash apps).

I got a perspective on procrastrination by playing chess. Sometimes in the past I would try to do something like write an essay, read a book or, program something. And I would get this heavy feeling in my brain. Thinking would be like running through molasses. No useful thoughts would pop out. I would have read the same sentence over and over, because as soon as I finished reading it I would have forgotten what I just read. And then I would drop what I was doing and "procrastrinate".

Well, I started playing chess. And the same thing would happen, I would get this feeling. And I would start dropping pieces. I would play the opening out of order. I would try my very best to prevent these things and then run out of time. And it made me realize something - because chess is a microcosm model of thinking and knowledge work, more quantifiable and objective - it made me realize that I wasn't being lazy. I had in fact been completely correct when I thought to myself that I can't do this right now. It wasn't an excuse.

But also it made me reflect on my "a-game". It's simply not possible to always be on your a-agame, and you have to plan around that. Somethings are acceptable to do at a lower standard. Maybe it's okay having half-understood the book? Also doing things at your "b-game" is still practice even if the work is garbage.
