I don’t think this really has much to do with fidelity/clarity, so much as accuracy. One could have an extremely high fidelity visual of a bike that is incorrect and you wouldn’t say they had aphantasia as a result.

I have aphantasia, I have no voluntary visual component to my mind as far as I can tell. I also have quite a good memory. If I were to draw a bike from memory I suspect I would make similar mistakes as those.

One thing I have noticed in the threads that come up about aphantasia is comments either directly or indirectly calling into question its validity. I want to share a test I got from another HN comment, so I won’t take credit, that I have found to be the easiest way to explain to people how completely absent the visual component is for me.

Close your eyes and imagine a ball bouncing across a table. Imagine the sound it makes as it goes. Bounce. Bounce. Bounce. What colour is it?

Most people I ask answer this question without hesitation. It’s easy, because they were just looking at it, maybe still are. I have asked this question of various friends tens of times, and I still don’t know what colour the ball is for me because it doesn’t exist. I know what a bouncing ball looks like, I know the sound it makes. I know what colour it could be. But I’ve never seen it.

That is aphantasia. It’s not foggy, or blurry, or “low fidelity”, it’s just nothingness.

> This feels like a cheap trick to drive users towards Claude Code

How did you come to this conclusion? It’s very much like he remarked: OpenAI acquired Windsurf, OpenAI is Anthropics direct competitor.

It doesn’t make strategic sense to sell Claude to OpenAI. OpenAI could train against Claude weights, or OpenAI can cut out Anthropic at any moment to push their own models.

The partnership isn’t long lasting so it doesn’t make sense to continue it.

> That was always intended to be... [something else entirely]

That's not what he said, anyone can invent excuses after the fact but that doesn't change the facts.

Musk simply pulled the "Don't be evil" trick, in so many words. Oops, sorry, not being evil helps the competition - which has also been slapped with 150% tariff, just in case.

I replaced the four screws in the bottom of my laptop(air m4) with hex bolts retaining a FLIR neckstrap and homemade torso strap. It makes a great walking laptop but I would add I'd much rather some kind of AR setup for this as the T-rex-arms are really only good enough to type out a prompt before the cramping sets in

Agreed, knowledge of how to use an energy source is as important as its presence. The former will not have the opportunity to emerge without the latter, though the former may be the more proximate cause of a "revolution". (I think it's important to emphasize material inputs because it is a common and very consequential misconception that prosperity is driven by human ingenuity alone.)

I didn't know that about coal! Thanks.

I'm confused as to why they are using a tree model to describe the archive objects (the current model and newly minted child).

It seems to me that this is a linear process (parent -> mint new improved model -> evaluate model, if it passes -> mint new child -> make newly minted child the parent)

I feel like this makes a linked list model rather than a tree model. Am I wrong? What are the other nodes (outside of parent and child) supposed to be?

By tautology, if you split the language, you split the language. Different groups will exhibit divergent evolution.

> current orthography is highly divergent from the actual spoken language, which is a problem in its own right

The orthography is no more divergent to an Australians speech as to an American's speech, let alone a Londoner or Oxfordian. But why would it be a problem?

> Or at least it used to be?

I chose not to write it earlier but my candid thoughts were that he seemed too old to still be doing this. Its just younger enthusiasts and professional gamers that do this, and the younger enthusiasts eventually get enough money for a mac and choose that.

The PSU is completely overkill, as if he was going to get GPU's. But then he has this completely outdated and old, power inefficient GPU in it instead, which is nothing to brag about and doubly warrants an explanation if the rig is to be explained at all. All while newer GPU's from the same company solve all of his driver and OS problems.

Flabbergasted is the right emotion.
Show HN: OpenAI-C – A lightweight OpenAI Chat API client in pure C
by LunaStev | 2025-06-06 02:28:57+00:00
Hi HN,

I just released openai-c, a lightweight C11 client library for the OpenAI Chat Completion API (like gpt-3.5-turbo). While openai-python is widely used and officially maintained, I made this for those who still enjoy working in C or need a small, native integration without Python dependencies.

Written in pure C (C11) Only uses libcurl and cJSON Supports both default and custom model names MIT licensed CMake and Makefile support

If you're a C programmer and want to integrate OpenAI into your low-level tools, embedded projects, or just love the language – I’d love your feedback or contributions!

GitHub: https://github.com/LunaStev/openai-c

Thanks!

It's pretty easy to figure out max capacity of any of those businesses. Audit the traffic and compare against reported figures. So yeah, you can get away with it, but can't go overboard. It's safer to just waste some high margin inventory to keep. A bar I used to go to was a ML operation and they would just ring in lots of expensive drinks throughout the night and then the boss would come in and settle up the registers. No matter how much I drank my tab was always $20. The same was true for pretty much anyone that was a regular. It was great because it was definitely impressive to order a round of patrons shots for everyone at the bar. On a busy night there would be a couple instances where the DJ would bring up one of "the guys" and let him announce that the DJ was gonna play his 3 favorite songs and while they were playing everybody in the bars drinks would be on him. Very fun.

check out SigNoz: https://github.com/SigNoz/signoz

We started building signoz as an OS alternative of Datadog/New Relic four years back and opentelemetry-native from day 1. We have shipped some good features on top of Opentelemetry and because of OTel's semantic conventions & our query builder, you can correlate any telemetry across signals.

>Generally, my advice would be to stick to country code TLDs.

Why? Unless you're talking about the country code of the same country you are operating in, (mis)using ccTLDs is basically gambling your domain's survival on the generosity of the country or even the very survival of the country itself. See Mali taking back .ml domain for a recent example.

Just stick to .net, .org or maybe .com for stability sake with only slightly higher but capped pricing.

I have this too, or something similar at least. I have the same issues around visual memory and first person memory.

I noticed it specifically when talking to my wife about remembering feelings and emotions. I have a lack of empathy (different to sympathy) and when looking back at past events I struggle to feel the emotions I was feeling at the time. I can recreate them using facts and things I understand but it's different to experiencing the same feeling.

The author of the article doesn't touch on this so I'm curious to know if they have the same experience.

The great vowel shift happened in the 16th century and is responsible for most of these changes. The original grammatical simplification (loss of cases etc.) between 10-1300 is difficult to ascribe, as similar happened in continental Scandinavian languages (and the Swedes had their own vowel dance!) But the shift in words themselves came much after (and before empire).

> which is present on the drone and use direct IMU input and ESC commands from the Jetson

Does the jetson board even have the appropriate UARTs on it to talk directly to the ESCs? Your typical hobby grade 5" class size ESC (either 4-in-1 or discrete) cannot talk to two different controllers at the same time. If it's already wired to the four UART outputs from a 30x30 size flight controller (such as something STM32H7 based running betaflight), the ESC cannot be in communication with any other device.

I’m realized years ago I have full blown aphantasia. But I don’t suffer from autobiographical memory deficiencies. For me it’s akin to what happens when you close your eyes for a moment then open them again. I’m not shocked by everything in the room “appearing” suddenly. I knew it was all there, but not because I visualized it while my eyes were closed. So when I remember past events, it’s with that same sensation of being there but just having closed my eyes to it. I do dream with full imagery.
by brookst | 2025-06-06 02:37:23+00:00
I 100% agree with you except your framing makes it sound like the model providers are doing something wrong.

If I spend a ton of money money making the most amazing ceramic dinner plates ever and sell them to distributors for $10 each, and one distributor strikes gold in a market selling them at $100/plate, despite adding no value beyond distribution… hell yeah I’m cutting them off and selling direct.

I don’t really understand how it’s possible to see that in moral terms, let alone with the low-value partner somehow a victim.

Get on a bike in Boise, Idaho and "blow through a red light" (making sure to stop and yield to oncoming traffic, first). It's not necessarily as small as you might think. And you know, don't ride your bike on the interstate, because that would be totally stupid.

But you know, go downtown, and ride around a bit in traffic, on the greenbelt, etc. And you'll see the cyclists are typically going to make a better decision for themselves and others than cars will.

Like I said, it's fine. If you can't understand it, maybe go experience it first hand.

Dear Apple AirPods 4 / Pro 2 / Pro owners,

When you're in a conference call over the net and listen to music simultaneously, do the earbuds output STEREO music?

There's apparently AAC-ELD-Stereo48K+voice and LC3-Stereo48K+voice modes on AirPods Pro, but neither recent iPhones nor macOS could activate it AFAIK.

I often cannot recognize people I know mildly well, especially if I lack context clues. This is not due to carelessness: trying harder does not help. But I do not have complete face-blindness.

Whether this means that you are wrong about when prosopagnosia is a continuum, or whether it means we should characterize how things work for me in terms separate from prosopagnosia (and thus perhaps in terms separate from face-blindness), I do not think it is productive for you to basically insult me and everyone like me by attributing our behavior to not trying hard enough. I've tried quite hard.

It's very socially bad not to be able to recognize people. I pay high costs for this inability and I would love to eliminate it if I could. I think (as the OP suggests) being aphantasiac might make it difficult for me to remedy this inability, because having a visual memory might be the best (the only?) way to record features of faces well enough to recognize people you know mildly well. I am aphantasiac and that too is something I cannot remedy. I would appreciate not being lumped in with assholes.

I'm out of touch with RF technology lately. But there are some immediate applications that I can think of, where a community approach can yield interesting results. That 'long wavelength' part in your question would necessitate receiver antennas with a large radio aperture to get some reasonable spatial resolutions - sometimes on the order of kilometers. The practical way in which this problem is addressed is using signal processing techniques like Aperture Synthesis and Very Long Baseline Interferometry (VLBI).

If the worldwide community can share the cost by deploying cheap receivers and donating compute time, it can lead to some interesting results. Much of these already exist, but they do have room for innovations and improvements. It's also a fun way to demystify these seemingly esoteric concepts.

The best that I can tell, this disconnect is explained by how the term "feminism" is used in an academic context and how that differs from its use in a casual context. In the academic context it's an analytical framework that looks at the world around us through the lens of gender dynamics. This is very different from the casual meaning of political activism for females.

This paper uses feminist theoretical frameworks like standpoint theory and intersectionality and so calling it a feminist analysis is a matter of intellectual precision more than it's a matter of it being a problem for women in particular.

Honestly I've learned a lot about feminism and what it is and isn't in researching these answers. There's apparently a lot more to academic feminist theory than empowering women.

Classic fixed / variable cost fallacy: if you look at the steel and plastic in a $200k Ferrari, it’s worth about $10k. They have 95% gross margins! Outrageous!

The ROI of unknown unknowns is by definition unknown.

I'm always amazed by people who speak fancy econ language like "ROI", economics is an abysmal example of science, it can't predict or solve anything but you're arguing for making it the arbiter of all other sciences? That's going to end as everything econ - in another great depression or war.

They might still. Why not?

Illustrates a risk of building a product with these AI coding tools. If your developers don't know how to build applications without using AI, then you're at the mercy of the AI companies. You might come to work one day and find that accidentally or deliberately or as the result of a merger or acquisition that the tools you use are suddenly gone.

I’ve gone through periods of life where I didn’t recall dreaming for years at a time, and others where I have frequent, vibrant dreams. I’ve had sleep paralysis many times when I was younger, a handful of extremely lucid dreams, times when I close my eyes and see nothing, and times when I can close my eyes and visualize clear, fully-actualized images.

I bring this up for two reasons: I wonder how fluid this sort of thing is, and I wonder what factors can dial up and down the intensity. Nicotine, patches in particular, absolutely supercharged my dreams to be bright, vivid, insane, bizarre hallucinations.

In general, my memory of novel events / odd connections / hilariously specific details is quite good, going back many years. I can also forget what I’m supposed to be doing right now within minutes. I can often remember when/where/how I read/saw something but not WHAT I read, so I have to retrace my steps to get to where I know the information is that I’m seeking.

It all seems to oscillate and shift and it’s fascinating.

in a job interview

"Tell me about a time when you tripped over while commuting."

"Tell me about a time when your feet touched each other during a walk."

"Tell me about a time when you were facing north-east and a bus passed in front of you." [follow-up question] "What type of bus was it? [suburban, long distance, etc] You say you saw it, so walk me by your visual experience."

If you have lived your life as a walking person, as you seem to imply by your comment, you surely have done these things multiple times, right? Failing to respond in a truthful and satisfactory manner will be counted heavily against you.

This is good feedback to make things more clear :) HyperDX is part of ClickStack, so ClickStack = { HyperDX, ClickHouse, OTel }. This is the stack we recommend that will deploy in seconds and _just work_, and can scale up to PB+ and beyond as well with some additional effort (more than a few seconds unfortunately, but one day...)

HyperDX v2, the version that is now stable and shipped in ClickStack, focuses more on the querying layer. It lets users have more customization around ClickHouse (virtually any schema, any deployment).

Optionally, users can leverage other ways of getting data into ClickHouse like Vector, S3, etc. but still use HyperDX v2 on top. Previously in HyperDX v1 you _had_ to use OTel and our ingestion pipeline and our schemas. This is no longer true in v2.

Let me know if this explanation helps

Thank you very much for a great reply but in no way can I see how destroying unsold vehicles can never be better in selling them for less.

If you say they can't lower the price because it signals to investors there's a problem doesn't it signal the same problem having a massive amount of vehicles unsold and then destroyed? How is one signal better than the other? So they're signaling they've got so much money they just don't care? That also seems like a bad signal to send. Far better to say publicly, hey we made a mistake this vehicle is not selling now we're going to sell what we made for less and stop making it.

None of this theorizing about signaling to investors makes any sense as long as we know that the vehicles aren't selling.

Stanford was edgy enough to reefer to “toking” in the moniker, but exercises restraint by depicting the titular thunder lizard smoking a putatively conventional tobacco cigarette.

I am hoping to use this “Tokasaurus” nickname with affection for my neighbors. If Stanford is ok with informal usage.

Success with Meta AI / Llama 4:

Hey Meta, I would like to see an image of a Tyrannosaurus Rex, who is clad in a leather jacket, sunglasses, and fedora. He is so cool looking, and smoking a joint of marijuana, and his image is superimposed against a skyline of Phoenix in the golden glow of sunset.

Can you light up the joint with a glowing tip?

I'm a staff ML engineer trying to internalize modern GenAI concepts, and wrote this to explain LLM buzzwords (RAG, RLHF, MoE, etc.) through a fantasy metaphor. It’s a follow-up to two other stories on how LLMs and RAG systems work. Would love feedback from the HN crowd.
by catlifeonmars | 2025-06-06 02:48:07+00:00
Yeah that was very hand wavy on my part. What I meant to say is that LLMs encode the relationships between words. The idea being that the relationship between words is a good enough representation of the relationship between the things that the words represent.

I am conjecturing

1. that solely relying on written artifacts by produced by humans has some upper bound on the amount of knowledge that can be represented.

2. that language is an inefficient representation of human knowledge. It’s redundant and contains inaccuracies. Using written artifacts is not the shortest path to learning.

For example, take mathematics. It’s not sufficient to read a ton of math literature to effectively learn math. There’s a component of discovery that comes from e.g attempting to write a proof that can’t be replaced by reading all of the proofs that already exist.

Anyway I would take all this with a giant grain of salt.

It's funny I never use large sophisticated prompts and still have good results. Something like:

> Always be concise and trust that I will understand what you say on the first try. No fluff in your answers, speak directly to the point.

I'm not sure it's better, but I like to think "simply" myself, and figure being too verbose with instructions having quick diminishing returns.

I wonder whether OpenAI legal can make the case for storing fuzzy hashes of the content, in the form of ssdeep[1] hashes or content-defined chunks[2] of said data, instead of the actual conversations themselves.

After all, since the NYT has a very limited corpus of information, and supposedly people are generating infringing content using their APIs, said hashes can be used to compare whether such content has been generated.

I'd rather have them store nothing, but given the overly broad court order I think this may be the best middle ground. Of course, I haven't read the lawsuit documents and don't know if NYT is requesting far more, or alleging some indirect form of infringement which would invalidate my proposal.

It's cute but unless you really need the size+ onboard screen, I don't see the big win of this over an Apollo air-1. (Esphome based, easy HA integration.

Or an inkbird - I paid $99 for one with co2, HCHO, AQI, PM2.5 PM10, TVOC, Temperature, Humidity. It has a display and integrates with home assistant. Built in battery if you want to move it around.

I own both of those. A DIY it but I haven't seen a good reason to.

The analogy is a bit like this. Imagine that there are 100 ceramic dinner plates for $6 each. Now someone comes in and buys them from you for $5 each - undercutting your margin. Then a 3rd company comes in and literally eats your lunch on your own ceramic dinner plates. The moral of the story is any story involving ceramic dinner plates is a good one, regardless of the utility of any analogy.

Another nice thing about markdown is that you can pick up the formatting even if reading the markdown in plaintext.

So lists look exactly how you would expect lists to look like if you were writing it on a piece of paper.

Italic/Bolds are surrounded by /* which convey emphasis even in plaintext.

Headings prefixed by # is a reasonable way to depict headings in plaintext and convey the intention immediately even if you don't know Markdown.

I think I have aphantasia, and there's two interesting things about this to me.

One, I couldn't tell you what sound a ball makes when it bounces on a table. I've never thought about absence of other senses but, thinking about it a bit, I can't really think of what a glass feels like or a fire smells like either. I have descriptions for all of them, like a glass is hard or a fire smells like.. smoke? Not really the best description. But in all of these cases, I instantly know I'm touching a glass or smelling a fire when it happens.

Two, I only thought of the ball in terms of the parabola it makes. When I read the color question, I can assign a color to it, but nothing in my "imagination" changes. There's just another word, blue or whatever, associated with it.

Thanks for making me think!
