The specific NPU doesn't seem to be mentioned in TFA, but my guess is that the blessed way to deal with it is the Neon SDK: https://www.arm.com/technologies/neon

I've not found Neon to be fun or easy to use, and I frequently see devices ignoring the NPU and inferring on CPU because it's easier. Maybe you get lucky and someone has made a backend for something specific you want, but it's not common.

You obviously know they can't be trusted, you just said so.

Why not just say that as a disclaimer to the video, instead of attempting to "get ahead" of other people who also know that, and will call you on omitting it.

Don't dismiss HN users as "certain crowds" and preemptively try to head them off at the pass for pointing out what you chose to omit. What "certain crowds" would that be, people who don't tolerate bullshit?

It's not about "certain crowds" who know Joe Rogan and Bret Weinstein are full of shit, it's about Joe Rogan and Bret Weinstein being full of shit, and you knowingly repeating their shit.

FIFY:

>Joe Rogan and Bret Weinstein are full of shit, but I enjoyed the most recent Bret Weinstein interview on Joe Rogan [0] where Bret talks about his pet theory on natural selection / evolution (maybe 2/3 way through the interview), which is bullshit.

Then don't just repeat their bullshit without question. You could have even gone as far to explain WHY they're full of shit instead of just propagating their bullshit without warning, as if "certain crowds" are trying to suppress that vital information.

When you uncritically recommend and parrot bullshit, and try to preempt comments from "certain crowds" who you know disagree, it sure comes off looking like you believe it.

It already exists in the form of Discord and Slack. Folks looking for a generic community need that community to exist en masse before they sign up. This is the problem dating apps have. No one is interested in joining because no one is in there.

Semi-private social apps that are invite only (like a company's Slack channels) or require discovery (like a game's Discord) have made lots of money and neither of those companies uses ads.

- Go hangout where your potential buyers hangout. It could be LI, IG, TikTok, Golf clubs, High end bars, Charity events. Make those connections.

- Make two (nested) lists - the people you know in real life- and the people they might know. Now, can any of these people be your potential buyers? if they are in first list, good, just talk to them, if they are in second list, ask for an introduction from your connection in first list.

- Advertise where your potential buyers might notice.

We are in an era where our financial shenanigans go unregulated never mind prosecuted. Everyone can see that the TSLA emperor has no fig leaf for a near-infinite PE ratio.

Absurdity is everywhere. The Tesla P/E ratio seems like a quibble compared to the really frothy part of the AI economy. Building new nuclear reactors, which takes 20 years, isn't going to power all the chips already waiting to be powered up. The response to that fact is to proposed to shoot it into space.
by cortic | 2025-12-27 15:44:04+00:00
That is really interesting; Though i suspect its just a effect of differing training data, humans are to a larger degree trained on spacial data, while LLMs are trained to a larger degree on raw information and text.

Still it may be lasting limitation if robotics don't catch up to AI anytime soon.

Don't know what to make of the Safety Risks test, threatening to power down AI in order to manipulate it, and most act like we would and comply. fascinating.

This. The issue is the culture inside many of these HW companies that is oppositional to upstreaming changes and developing in the open in general.

Often an outright mediocre software development culture generally, that sees software as a pure cost centre, in fact. The "product" is seem to be the chip, the software "just" a side show (or worse, a channel by which their IP could leak).

The Rockchip stuff is better, but still has similar problems.

These companies need to learn that their hardware will be adopted more aggressively for products if the experience of integrating with it isn't sub-par.
by thunky | 2025-12-27 15:44:19+00:00
> So you really believe that we arrived to the end of software?

No that's not what I'm saying. I'm saying that demand (for a product or service) is what drives the amount of labor that is performed, not the other way around.

If a company has maxed out the amount of widgets the can sell in their market and adding new features will not change that, then adding more labor makes no sense.

It follows that making their existing labor more productive leads to layoffs.

I spent the last 6 months building a bridge between Claude Desktop and my local Python quantitative models.

It uses the Model Context Protocol (MCP) to let Claude 'consult' a regime-switching LSTM model before answering questions about stocks.

The wildest one is how people say just because you produce open source software you should be happy that multibillion dollar corporations are leeching value from your work while not giving anything back but are in fact making your life harder. That’s the biggest piss on my back and tell me it’s raining bullshit I ever heard and makes me not want to open source a damn thing without feeling like a fool.

Not sure what do you mean. I.e., what exactly is supposed to be the tricky part. Yes, I've dealt with quite a few processes like that, but I never tried, or would ever want to to put this into crontab. In fact, I don't know how the author intended his article, but if you consider doing that for production, I strongly advice you not.

What you do instead, is you schedule the cronjob for the most generic case, e.g. each day. And if it does not need to run 3 days before holidays with crescent moon when wind is blowing from the south, it is just the part of business logic of the process, which you write in the any proper programming language that you prefer (or that the system is written in anyway).

Now, how do you manage the list itself depends on the details and I've done all sorts dirty things that one probably shouldn't do (cutting corners), but in the most flexible case it is just some CRUD-type page in your back-office system, with a real UI, and there is a person (usually in the bookkeeping department of the company) who has it among his responsibilities to maintain the schedule. You store it in some proper SQL database and cache it aggressively, so the the myriads of cronjobs don't bother it more than necessary.

Our firm uses python extensively and the virtual environment for every script or script is ... difficult. We have dozens of python scripts running for team research and in production, from small maintenance tools to rather complex daemons. Add to that the hundreds of Jupyter notebooks used by various people. Some have a handful of dependencies, some dozens of dependencies. While most of those scripts/notebooks are only used by a handful of people, many are used company-wide.

Further, we have a rather largish set of internal libraries most of our python programs rely on. And some of those rely on external 3rd party API's (often REST). When we find a bug or something changes, more often than not, we want to roll out the changed internal lib so that all programs that use it get the fix. Having to get everyone to rebuild and/or redeploy everything is a non-starter as many of the people involved are not primarily software developers.

We usually install into the system dirs and have a dependency problem maybe once a year. And it's usually trivially resolved (the biggest problem was with some google libs which had internally inconsistent dependencies at one point).

I can understand encouraging the use of virtual environments, but this movement towards requiring them ignores what, I think, is a very common use case. In short, no one way is suitable for everyone.

How are we still in a world where there are breathless, hand-waving blog posts written about the theoretical potential of super-fast SBCs for which the manufacturer shows fuck all interest in competent OS support?

Yet again, OrangePi crank out half-baked products and tech enthusiasts who quite understandably lack the deep knowledge to do more than follow others' instructions on how to compile stuff talk about it as if their specifications actually matter.

Yet again the HN discourse will likely gather around stuff like "why not just use an N1x0" and side quests about how the Raspberry Pi Foundation has abandoned its principles / is just a cynical Broadcom psyop / is "lagging behind" in hardware.

This stuff can be done better and the geek world should be done excusing OrangePi producing hardware abandonware time after time. Stop buying this crap and maybe they will finally start focussing on doing more than shipping support for one or two old kernels and last year's OS while kicking vague commitments about future support just far enough down the road that they can release another board first.

Please stop falling for it :-/
by ndriscoll | 2025-12-27 15:46:24+00:00
My uninformed normie view of the ecosystem suggests that it's the support for almost every particular board, and that's exactly the issue. For some reason, ARM devices always have some custom OS or Android and can't run off-the-shelf Linux. Meanwhile you can just buy an x86/amd64 device and assume it will just work. I presume there is some fundamental reason why ARM devices are so bad about this? Like they're just missing standardization and every device requires some custom firmware to be loaded by the OS that's inevitably always packaged in a hacky way?

I did my PhD on fibre lasers, 0.1 DB would have been considered a ver bad splice and I would have recut and respliced (if you have 1-10W in your cavity that 0.1 dB loss would risk burning and the fuse propagating through your cavity destroying everything in its path (as a side not look up Videos of fibre fuse, looks fascinating). In my experience 0.01-0.02 is much more typical than 0.1 dB loss.

I’m sharing not arguing. This is the comment section of a website. I sold my autonomy for a wage doing other things, but I happily accept my affliction of contemplating the universe. Maybe it will spark something in the imagination of someone. Amateurs thinking is what led humanity to this point. I clearly stated my lack of domain expertise- but I reserve my right to unprofessionally question foundations and reject treating silence about first principles as intellectual virtue. I also accept, with grumbling, the downvotes.

> Have you had any "learned the hard way" moments?

A big lesson for us is that you still need to be careful even in a sandbox.

We've been running Claude/Codex/Gemini in sandboxed YOLO mode and have seen some interesting bypass attempts. [1]

A few examples:

- created fake npm tarballs and forged SHA‑512s in our package‑lock.json

- masked failures with `|| true`, making blocked operations look successful

- cloned a workspace, edited the clone, then replaced the workspace w the clone to bypass file‑path deny rules

So, we’ve learned to default to verbose logging, patch bypasses as we see them, and try to keep iteration loops short.

> Not really sure how else I was supposed to interpret your comment

Yes, that was a bit facetious of me, I apologize for that.

> What is so bad about the existence of this project?

Being very blunt: The fact that it reinforces the extremely common misconception that a) converting between containers like mkv and mp4 will always require reencoding and that b) there is a single way to reencode a video (hence suggesting that there is no "bad" way to reencode a video), seeing as next to no encoding settings are exposed.

Every community I have lived in has benefitted enormously. I grew up in Washington state and built my first company here, employing several people in landscaping. When I lived in Los Angeles, I built a company employing over 100 Californians. Now that I am back in Washington state, I have a farm employing 5 people and have invested hundreds of thousands of dollars in the local economy.

I have NEVER taken any benefits from the government. I have paid millions of dollars in taxes in California and millions more to Washington state. City and counties have likewise collected huge sums from my work.

People who move from place to place can contribute more than people who stay in one place living off the system.

>Stimulants reversed the behavioral and brain effects of sleeping less

Supporting this observation: https://www.frontiersin.org/journals/psychiatry/articles/10....

I've been looking for theories for why 10mg Adderall seems to give me a brief feeling of drowsiness ~30 minutes after taking it.

The state regulation theory (§3) in this article might suggest that the process of returning to baseline could feel like sleepiness https://www.frontiersin.org/journals/psychiatry/articles/10....

Which makes more sense if the sleep disorder explanation for ADHD means that the normal feeling of sleepiness is not properly functioning.
by pron | 2025-12-27 15:50:34+00:00
Except it suffices to know that some construction that supports the integer/natural axioms exists without having any specific theorems, such as 1 ∈ 2, about its specifics. In fact, in TLA+, which contains a formalised set theory, the construction is not part of the definition of the integers, and 1 ∈ 2 (or any other theorem about the construction of the integers) is not provable (of course, 1 ∉ 2 is not provable, either). The details of the construction can remain unknowable.

Anyway, my point is that type theories contain at least as many junk theorems as set theories, if not more, and junk theorems are fine either way. Neither approach is more philosophically pure. Any claims to that effect are really an expression of personal aesthetic preferences.

The attached post feels AI-generated/AI-edited. I don’t know why that detracts from the usefulness of this utility, but it — at least how I’m reacting to it — seems to.

For me, it reads as not having any soul to it, as well as changing who its target reader is throughout the post. The choice of emphasis comes across weirdly too.

I think this is a wonderful tool, but whether it’s because the author uses AI to help them write this post, or that there’s AI edited content everywhere now, I’m weary of reading and trusting something that reads like this post does.

I don’t know if this is overblown or meta-commentary on the state of online posts these days, but it’s how I’m feeling, more and more, when I see online writings.

I downvote people who express things disrespectfully, like saying they're "embarrassed on behalf" of people who don't think like them.

So yeah, I'll be a totalitarian censor against people who put down others while expressing their opinions.

They also requested that people explain their downvotes, so I did, but I also find it objectionable to say something like "I'm embarrassed for you, but if you downvote me, you owe me an explanation." That's a one way street for respect.

Also LLMs. Also television. Also smart phones, particularly those. Also books, the wrong ones can really cripple the intelects. Also talking to children, they can be so cruel. And adults too. Also math and chess, they can send people right over the edge. It's astonishing how many mental health threats are insufficiently labeled, no wonder people are so messed up.

> It's because the comment was so poorly communicated and because the author was so profoundly out-of-touch with the average person that they had lost all perspective.

None of those things are true. Which is the point I’m making. Go read the original conversation. All of it.

https://news.ycombinator.com/item?id=9224

Don’t skip Brandon’s reply.

https://news.ycombinator.com/item?id=9479

It is patently absurd to claim that someone who quickly understood the explanation, learned from it, conceded where they were wrong, is somehow “profoundly out-of-touch” and “lost all perspective”. It’s the exact opposite.

I agree with Dan that we’d be lucky if all conversations were like that.

When have you bought something?

Example 1: The other day I was trying to fix a sprinkler. My results were mid, then I saw a truck at my neighbors house with a phone number.

1. I was not in the market for sprinkler repair until that day.
2. I was too busy to make a market comparison, seeing that my neighbor did it was enough.

Example 2: I was thinking about refining my mortgage this year. My current servicer called me one day with an offer. It was a competitive but not t optimal deal, but the lady on the phone signaled to me she understood my values and would get it done.

That’s what you are looking for with outbound, people who are in need, willing to part with cash, but probably not shopping for the thing.

This is why cold calling works and why volume is so important. You aren’t trying to persuade people who aren’t interested, but trying to find those who are.

The biggest fear of people with money is not spending money, but that what they pay for won’t work out.

Well done! Government agencies tend to always seek more funding and never change or close down even when everyone universally agrees change is needed. Good to see change here.

The shrinking of the federal government is much needed as there is no mechanism to remove dead wood like bankruptcy does for private industry. We do need a smoother mechanism than just hacking whatever is not protected by insane public employee unions though.

> some of them spaced and extra long; apparently this publisher had a very “inflationary” style!

It's pretty common to see a single em-dash for the comma-like parenthetical usage (p6 etc.) and a double em-dash for the "someone's dialogue was interrupted and cut off" usage (p15).

The "I'm redacting this name" usage (p11) often uses two em-dashes too, although Wodehouse('s typesetter) doesn't in this case.
by tux3 | 2025-12-27 15:55:15+00:00
There is still a guardrail. The blog post explains that it is just using different functions and notation which might allow things like 0/0. But at the end of the day, different notation still cannot be used to prove false things.

In other words, you can use all these junk theorems to build strange results on the side, but you can never build something that disagrees with normal math or that contradicts itself. There is no footgun, because the weird results you obtain are just notation. They look weird to a human, but they don't allow you to actually break any rules or to prove 1=0.

The post is brilliant, interesting, and deeply performative. It can be all those things, and more. It feels like being shown a display case at your friend's private library ("Did you read them all?" "Oh, these are just for this week" — Umberto Eco used this reply when folks asked him about his 50k books). Obscure references, namedropping, the right doses of self-deprecation, the footnotes (gosh, the footnotes!)

Nobody writes like this just for themselves. It's for the show. It's their mansion of words and it's there to wow bystanders. Mind you, I'm not condemning, just merely stating why the post somewhat irks me. I respect the intellectual depth of the author; I might even have a beer with them (though it couldn't be a standard lager, I guess).

Edit: I'm commenting on the post, not on the author. I don't know them. I'd love to.
by beAbU | 2025-12-27 15:56:51+00:00
Yes, because the vast majority of self proclaimed and vocal so called "Christ"-ians have completely forgotten about (or conveniently abandoned) the teachings and philosophy of Christ the man.

Nobody can claim with a straight face that the "Christian Right" movement in the US can be classified as wholesome love-thy-neighbour Christianity. Because from where I'm standing, it's far from it.
Show HN: Goodreads Analyzer – AI roast and book recs from your reading history
by DoingSomeThings | 2025-12-27 15:56:58+00:00
Inspired by the HN Wrapped Roast (https://news.ycombinator.com/item?id=46336104), I built a web app that analyzes your Goodreads library and generates a literary roast, personality profile, and book recommendations.

Upload your Goodreads export CSV and get:

- Reading stats

- A roast of your reading choices

- Inferred personality traits

- Year-by-year thematic analysis

- Personalized book recommendations

Uses Gemini API for analysis. Book data stays in browser (localStorage), only titles/reviews/dates sent for insights. Demo mode available if you want to try it without uploading your own data.

This started as an experiment in prompt engineering and pattern recognition. I was curious how much personality insight you could extract from reading patterns alone.

The results were surprisingly accurate. It correctly inferred my shifts in physical location, political beliefs, and religious affiliation based purely on reading history.

Would love feedback on the analysis accuracy or additions that would make this more fun to use.

I'd like some proof that the embedded programmers working for 'the man' at medical device companies are better and more motivated than those that are hacking on loop devices.

You're comparing people with a death wish in disguise with people that are extremely motivated to improve the QOL and they're very careful about how they do this, in fact if you read up on this you'd notice the insane attention to detail and the very rigorous process, on par with what I've seen in industry and in fact probably better than most.

All of this talk in this thread makes me think back to a time when people were laughing at that Finnish kid that was making his own OS with his buddies. Surely nobody would ever trust their business, their property or the lives to open source.

I checked and this is actually hacker news, not the BSA.
