Yep I guess the case is the limiting factor then, no CPU cooler can do much if the case traps the hot air inside. Though 5 fans should be enough to force quite some air to move already.

I had a fully new build so used one of the well reviewed Fractal cases to get good airflow, with 5x140mm case fans.

People care too much about food waste. Food waste is a result of food being cheap. If food stops being cheap then it stops getting wasted. (And when I mean cheap I'm talking about the price its purchased at at a bulk level.)

And you're not going to convince people to cut back on meat.

I also edited my post that people are considering putting solar panels on cropland because food is so cheap.

This general line of thinking is just flawed. You don't fix global warming by reducing consumption (of any form), you do it by changing the root source of how consumption is performed while continuing to increase consumption. i.e. solar panels and wind, not coal. There is no such thing as an low per-capita energy consumption rich country. Energy efficiency begets more energy usage, not less.

The same goes for meat consumption. If meat shortages start happening people will switch to more types of meat consumption (or meat product consumption) that come from more "manufactured" sources. Plant-based meat and grown meat should be going after the areas where they can replace inputs by being a cheaper product. For example, almost no one uses leather now because leather substitutes are cheaper and good enough.

It's happening to me with API Key usage. I assume there are no Terms of Use protections on our data unless we access Gemini CLI in a paid manner?

[API Error: {"error":{"message":"{\n \"error\": {\n \"code\": 429,\n \"message\": \"Resource has been exhausted (e.g. check quota).\",\n \"status\": \"RESOURCE_EXHAUSTED\"\n }\n}\n","code":429,"status":"Too Many Requests"}}] Please wait and try again later. To increase your limits, request a quota increase through AI Studio, or switch to another /auth method

However, in the Google cloud console I don't see any of the quotas going above their default limits.
Show HN: Delfyn, AI Agent to help businesses get paid faster
by jhack88 | 2025-06-25 21:06:39+00:00
Hi HN,

I'm Junior, founder of Delfyn, and I’ve been building an AI-powered agent that helps finance teams get paid on time. If you've ever dealt with slow-paying B2B customers, broken invoice matching, or cash flow uncertainty, this might resonate.

The problem: In B2B, waiting 60–90 days to get paid is common. AR teams spend hours manually:

- Reconciling payments to invoices

- Chasing customers

- Updating spreadsheets

Explaining why cash flow projections keep being wrong

Meanwhile, late payments quietly bankrupt 1 in 4 SMEs in Europe.

What Delfyn does: We built an AI agent that helps automate:

Invoice-to-payment matching using rules, embeddings (e.g. “0099” → “INV-2023-0099”), and retrieval models

Cash flow forecasting with transaction-level granularity

Proactive reminders + incentive recommendations to reduce DSO

We're combining deterministic logic (amount, IBAN, date) with semantic models (e.g. e5-base-v2) and LLMs (for gray-zone explanations only).

Who it's for: Finance teams (esp. in B2B SaaS, agencies, professional services)

Founders managing AR themselves

Companies tired of relying on NetSuite exports + wishful thinking. Or even worst sending payments collections emails to customers who have already paid. I've seen that a lot.

Back in the day, if you went to a website you could always tell who wrote their HTML by hand and who used a tool like GruntPage, Dreamweaver, etc. even without looking at the META tags. The by-hand stuff was like a polished jewel that had only as much layout, styling, and markup as needed to get the desired effect. The proprietary web editor stuff was encrusted with extraneous tags and vendor-specific extensions (like mso: attributes and styles in GruntPage).

Then as now, if you let the machine do the thinking for you, the result was a steaming mess. Up to you if that was accessible (and for many, it was).

Worst D-4 ever! But more seriously, I wonder how closely you could get to an non-uniform mass polyhedra which had 'knife edge' type balance. Which is to say;

1) Construct a polyhedra with uneven weight distribution which is stable on exactly two faces.

2) Make one of those faces much more stable than the other, so if it is on the limited stability face and disturbed, it will switch to the high stability face.

A structure like that would be useful as a tamper detector.

> Has anyone ever used .exe for anything other than Windows?

Did you know that Microsoft Windows originally ran on top of the much older MS-DOS, which used EXE files as one of its two executable formats? Most Windows users had lots and lots of EXE files which were not Windows executables, but instead DOS executables. And then came Windows 95, which introduced 32-bit Windows executables, but kept the same file extension as 16-bit Windows executables and 16-bit DOS executables.

Setups like that just sadly don't exist in my part of the world. But, in your case, totally agree. Keep renting and just smash your savings in to other investments. I'd be doing the same.

Meat provides a lot of nutrition that crops do not. How about we "cut back" on manicured lawns instead? Ornamental grass is the single largest crop in the united states; and while some of it goes to compost which can be used to grow food, an estimated 8% of landfill waste in the united states is lawn clippings. When grass is put in landfill instead of compost it produces greenhouse gases (not to mention all the fuel used in lawnmowers and garbage trucks).

The idea that these "marginal" spaces which exist right beside where people live, eat and work cannot be used for food production is a little silly. It used to be quite common before it was cheap to have food airlifted from 10000km away. Alternately, the "wild yard" thing provides a lot of habitat for innumerable species and helps support the bird population.

As a professor who teaches courses on media literacy and artificial intelligence, I am obsessed with our relationship with AI interfaces. I got tired of the default sycophantic glaze on ChatGPT and the tedious ritual of manually telling it to be more direct in every new chat. I'm also weary of the endless user engagement questions that GPT asks with every interaction.

As a weekend vibe coding project, I implemented this tool to fix the problem for myself. It’s a lightweight Chrome extension that lets you define and automatically inject a custom prompt to control the AI's personality.

This extension prepends the instructions to the user's message before each fetch request is sent. It's a "simulated" system prompt, but it works surprisingly well and I think this is more effective than relying on custom instructions.

This can also be adjusted mid-conversation without needing to launch a new conversation. It's 100% local. Nothing is ever sent to any server but OpenAI's. It collects zero data.

It's a simple tool for a simple problem. I'm sharing it here because I figure others might find it useful too. I'd love to hear any thoughts or feedback you have.

Engineers should be talking with customers at least some of the time, so that part is covered.

There is the strategy side of things which you won't get from talking to customers, but I've seen many cases where senior management make absolutely terrible (and obviously terrible, not only with hindsight) strategic messes, so I'm not totally convinced that senior management are necessary for this part either. Senior management do usually have a better overall picture - eg. that some product is losing money and some other product is growing rapidly - but that's usually because detailed revenue numbers are hidden from everyone below the C-suite.

I explicitly call out public libraries.

But I didn't get into that discussion, but even that system was borne out of Carnegie, an earlier hypercapitalist. That's probably the only reason why libraries are publicly accepted. And in reality, many Republican jurisdictions, they aren't accepted and are being actively defunded.

Well, what I was getting to was more of a European piazza style open area with businesses surrounding it so that people can attend somewhere ever to whatever.

The Atlantic suggests this results from the release of those convicted during a decades long crime wave, which apprently took place when many of us grew up. Perhaps it also tracks with a progressive decline in law enforcement. Whether that is because crime waves not longer exist or whether it is some other reason is a question for the reader. A substanbtial amount of crime is now done via internet. Few are ever convicted.

It also can't seem to create icons from another set and match the stroke weight, curvature, and other stylistic choices of another simple icon set. Seems it struggles with tight constraints. 10 years ago you would think it would be able to handle the visually "simple" things over the more complex ones it can do today. Sorry, my disappointment is showing isn't it?

Just to be clear, it's extreme in the sense that owning a car means you are more likely to have less money.

If you live in a house out in Queens and work as a plumber then you definitely have a car.

If you live in Manhattan or Brooklyn and work for an investment bank you probably don't.

Having a car in the city can be a real pain. A lot really depends on your lifestyle, if you need one -- like if you go rock climbing every weekend, you do. If you're into restaurants and clubs, you definitely don't.

Agreed. People don't realize that farming uses essentially all the land not because it needs all the land, but because that's the cheapest way of producing the required amount of food. We could produce more food on less land, but that would make food more expensive. In the extreme, a greenhouse can produce 1000x as many calories per acre than dryland farming can. But a greenhouse can't produce 100,000 calories for $6 like a dryland farm can. (1 bushel of wheat is almost 100,000 calories and sells for $6).

But more expensive food can and has provoked severe world-wide crisis. So that's what we need the second green revolution for -- to handle increasing demand without raising prices.

You're not going to reduce food costs with vertical farming, but radical approaches to meat and meat substitutes certainly can.

I think that's how it started out, and also how a lot of developers still conceptualize it. Wine has had to massively expand that scope to reach the maturity it has now. I think it's kind of straddling the line between "Implementation" and "translation".

Philosophically its still a translation layer though. It doesn't really care about correctness if the no apps depend on it. Success is in meaningfully running client software. The implementation of the Windows Libraries are just a way to get there.

I’m the person behind CollapseRAM. This isn’t a quantum computer it’s a symbolic memory system that simulates some informational behaviors of quantum systems, like collapse-on-read, entanglement, and no-cloning, using deterministic classical logic and RAM.

I’m not trying to replace physics or claim quantum advantage. I just wanted to see if we could model quantum-like constraints for key exchange and secure memory using symbolic logic alone and to my surprise, it actually works.

I’m not here to argue, just hoping the core idea gets a fair look. Thanks to everyone who gave it a moment.
by mlindner | 2025-06-25 21:13:39+00:00
Where do you think the nitrogen in nitrogen fertilizers comes from? The atmosphere. The key part of the Haber-Bosch process that needs to be replaced is the hydrogen, which could easily be done with on-site electrolysis if needed.

However only 1-2% of global CO2 output is from the fertilizer production industry. Oil use is never going to go away until it is truly gone or too expensive to pump out of the ground. As long as it's cheaper to use fossil fuels for chemical input stock companies elsewhere in the world from where regulations are will do so and that cheaper product will take over the market. It becomes a whack-a-mole of banning products further and further down the industrial pipeline to the point there's no way you can ban products made with fossil fuels.

The way out of this is to make competing methods cheaper. And if electricity gets cheap enough, then electrolysis sourced hydrogen becomes cheaper than fossil fuel sourced hydrogen and then your haber-bosch process will be carbon neutral.

Updates as marketing? Makes sense, but not well-executed by OP.

The update titles are good, but try focusing on the feature, not the “toil.” If I’m using your product and want the feature, you’re telling me what I already know. Keep text to a minimum.

Revised first example (duplicate button):

You can now create repeating events by clicking “Options > Repeat.” Sync with company holiday schedule to skip repeat events on holidays.

> The way you present it, with "good" vs. "bad", suggests that you're arguing for one, not for both, for release announcements instead of release notes.

I don't think release notes are bad, but I think adopting a release notes style for a release announcement is bad. Similarly, I think adopting a commit message style in release notes is bad.

I'll look for ways to clarify this in the article.

>> When vendors just publish a terse changelog, it feels like they don't care much about me

>That depends on what you mean by terse. "Bug fixes and performance improvements" is terse and careless. A comprehensive list of changes is not necessarily terse. And in a sense, "release announcements include only the most impactful changes" is terse too.

When I say "terse" I mean that they describe each individual change tersely. KeePass is an example of a vendor I think publishes release announcements with terse change rundowns, and I think the announcements suffer because of it.[0, 1] When minor changes get the same screen real estate as big new features, it's hard for the reader to recognize the important features because the signal to noise is too high.

Out of curiosity, what's your opinion of KeePass release announcements?

It's the same hardware on each test. The only difference are the drivers and OS in question. Lenovo has been slow to officially ship updated GPU drivers for this device, but the exact same SoC is used on a number of handhelds.

As for the performance, its a 15W handheld trying to play games that 600W PCs and 300W consoles struggled with just a few years ago.

Gemini web UI is extremely apologetic and self deprecating at times.

Therefore I was not surprised to experience Gemini spiraling into an infinite loop of self-deprecation - literally it abandoned the first command and spiraled into 5-10line blocks of "i suck"

---

Right now there is one CLI that influences and stands far and beyond all others. Smooth UX, and more critical some "natural" or inherent ability to use its tools well.

Gemini can also achieve this - but i think it's clear the leader is ahead because they have a highly integrated training process with the base model and agentic tool use.

UPD: Found the paper: - https://huggingface.co/papers/2502.09741 - https://fouriernumber.github.io/

in paper mentioned “number” is a single sort-of “token” with numeric value, so network dealing with numbers like real numbers, separately from char representation. All the math happens directly on “number value”. In majority of current models numbers are handled like sequences of chars

I'd argue that the laws that must be obeyed form an odd superset of the laws of the nation from where the organization is operating and the laws where the users are located. Where those laws intersect nicely, the mode of operation is clearly defined, where they do not intersect, the mode of operation becomes very tricky. (As we've seen with privacy, cookie laws, etc.)

This sounds like a red herring to me.

If the only way to associate a user with their ID is by fingerprinting them, you can do the same thing without an ID with having shadow profiles. If the proof system is designed for privacy, the ID doesn't make you more trackable.

In other words, if the ID never directly leaks companies can just make up a static ID for you and get the same results.

Some of these games are practically neck and neck for performance. I'm wondering if it's a similar situation to early Proton comparisons, where framerates were higher in Proton but when comparing still for still you could tell it just wasn't actually doing certain effects. Are there features that are being attempted in the Windows version that are just not functional and thus effectively disabled on the Proton one?

But even then, assuming that is true, if they're pretty much the same would people care about maybe some fog looks a little different but you get an extra 15-20fps in a game? I think a lot of people would still prefer the boost in frames.

I say this as an author who has definitely had a lot of my work slurped up by these machine-learning goblins: This was the right call. I learned to write by reading other authors' works, so I'd have to be quite the hypocrite to stop others from learning from me. Still, it makes me sad and tired to know that I'm unwittingly training my own replacement--one that will never be sad or tired itself.

In my view, one real gray area is in image/video generation, especially "x in the style of y" kinds of shenanigans. As a society we may need to consider some better protections for an artist's/studio's style, otherwise distinct and novel and interesting styles will become watered down into a sea of bland mimicry until the sweet release of the heat death of the universe.
Show HN: Towards agentic Graph RAG: Enhancing graph retrieval with vector search
by laminarflow027 | 2025-06-25 21:21:08+00:00
In this post, we document the results of some experiments comparing vanilla Graph RAG (just a single pass of text2cypher) vs. a router agent Graph RAG approach that can call vector search tools alongside text2cypher. The routing agent uses an LLM to decide which vector search tool to call, depending on the terms identified in the question, and it works quite well.

The results show that recent frontier LLMs like `gpt-4.1` and the trusty workhorse `gemini-2.0-flash` produce great quality Cypher reliably and reproducibly, with some prompt engineering to ensure that the graph schema is formatted well in the text2cypher prompt. Across a suite of 10 test queries (that are moderately complex and require paths to be retrieved from the knowledge graph), `gpt-4.1` and `gemini-2.0-flash` pass all tests, generating the right answers when a router agent is added to the workflow to enhance vanilla Graph RAG.

Prompt engineering is done using BAML (a programming language that makes it simple to prompt LLMs and get structured outputs from them in all experiments. In fact, the knowledge graph itself was constructed using BAML prompts that extract entities and relationships from unstructured data upstream.

A logical next step to this workflow is to build more complex agent loops that can run multi-step Cypher queries whose results can be consolidated to answer harder questions (similar to how a human would approach it). The general principles of testing and evaluation would apply here, too. Seems promising to explore these methods further!

We did wait for the “perfect” time, and are very happy we did.

I got my son at almost 40, and I’m positive I’m a much better parent because of that. Sure, kids cost energy, but at 40 and 50 you’re not geriatric. I often get the opportunity to compare our parenting style to younger parents, and it’s clear that they often have some emotional growing up to do themselves. They complain about normal parenting things that we just shrug about, they are torn between their career and raising a kid, and most importantly they often lack patience, where to us it just comes natural.
