Couldn't agree with you more. The internet has, to borrow the word of the moment, become enshittified, and people think that's "normal".

People accept that platforms should be centralised, and that they should harvest your data in order to sell it to adtech companies who will then feed it to an industry that learns in real-time how to prey on your darkest fears to sell you things you don't need but might make you feel slightly less sad for a second. And people just accept it: that's normal these days.

They even call it doom-scrolling, and don't ask "wait, should I want to scroll through actual doom? Is the occasional video that makes me smile really worth it all?"

Perhaps it's my age, but I can't understand anybody who says their main form of media consumption is YouTube. How? How do you actually put up with that, knowing what is behind every mouse movement and click, and the knowledge that every single pixel in front of you is being tweaked by robotic neuroscientists squeezing every drop out of A/B tests to make you feel like utter crap? Like, seriously, WTAF?

HN is popular within its niche precisely because it isn't like that. It is not "a platform", in the modern and now normalised sense. It links out to other sites and asks people to come back together to discuss what they saw there. Old school. No ad tracking. No doom scrolling. Pick what you like. Click it, don't click it. Discuss it, don't discuss it. Nobody is tracking "engagement". There's some gamification, but does anyone _really_ care?

This type of interaction is entirely native to my generation and older (I just squeak into millennial, on the older side), but feels completely bonkers to people who think Facebook, Instagram and TikTok are what is normal and how the Internet works.

Some of know they're not normal. We know they're aberrations, ghouls that prey on unwitting masses.

I worked in recruiting for a long time and I can tell you I never saw much in the way of any deliberate strategy to create fake job posts.

The thing is that whether or not a job exists at a point in time is far less black and white than you might naively think.

There are many reasons for it to be somewhat grey and banning the practice doesn’t really mean anything because you would have to quantify precisely under what circumstances a job is allowed to be advertised and as I say, it’s not as clear as you might imagine.

There is absolutely not a one to one relationship between a job and a job ad.

This is the same reason why I'm disappointed that Pinyin won over Wade-Giles. If Hepburn can be acknowledged to be better than Kurei-Shiki, then Wade-Giles is also better than Pinyin. At the very least we'll no longer have to deal with words containing q that's pronounced nowhere near q. Although admittedly it does produce some exotic looking words and boon for Scrabble players.

1:76 is a very popular scale for model railways in the UK, so I wonder if they design figures for that audience, then paint them in fatigues to expand the market range.

The US preferred 1:87 historically. English 1:76 and American 1:87 trains run on the same size track, but the English models are typically built slightly over-size because their smaller bodies wouldn't fit a good motor easily.

The link is just to the book, the details are scattered throughout. That said the page on GPUs specifically speaks to some of the hardware differences and how TPUs are more efficient for inference, and some of the differences that would lead to lower latency.

https://jax-ml.github.io/scaling-book/gpus/#gpus-vs-tpus-at-...

Re: Groq, that's a good point, I had forgotten about them. You're right they too are doing a TPU-style systolic array processor for lower latency.

Because the black americans are $5M less well off than if they had stayed in Africa, or ?

Don't get me wrong, slavery was (and is) a terrible thing that stains humanity. But at some moment we have to move on.

I fully believe that this continuous racial tension is fueled by US' enemies (e.g. could be Russia).

There was much less racial tension some years ago. And gender tension.

Firefox has made some shady choices of late. The settings functionality is getting ever more unreliable and they are moving more essential settings to about:config and then you have to go and dig around in there and hope you find all interdependent parameters. That is one thing that has definitelybdeclined: be open to your users and enable them to customise the software. All the ML settings can only be changed via editing the profile. How many non-techies go and dig around in the profile?

Most “AI for business” tools in 2025 are wrappers around a few cloud LLM APIs. BrainPredict went in the opposite direction: 445 specialized ML models across 16 business domains (commerce, supply chain, finance, HR, ops, etc.), running 100% on your own infrastructure, with zero ChatGPT or external LLM dependency.

What it does

445 pre‑built models for things like churn, demand, pricing, inventory, fraud, contract risk, SLA breaches, cash‑flow, maintenance, etc., organized into 16 platforms (Commerce, Supply, People, Sales, Marketing, Legal, Risk, Finance, Innovation, Controlling, Communications, Data, Strategy, Sourcing, Operations, Customer).

Everything runs on‑prem: training, inference, and logging stay inside your infra (Linux/Windows servers, VMs or private cloud); the vendor’s servers only handle license checks, docs and updates, not data.

Models are “classic” ML/DL (XGBoost, RandomForest, Prophet, ARIMA, PyTorch, TensorFlow, BERT, spaCy) tuned for specific KPIs; field tests show ~92–95% accuracy and lower false positives vs single general models.

An “Intelligence Bus” coordinates everything: >570 event types let models share signals across platforms (e.g., a demand spike prediction from Commerce can trigger Supply, Finance and Operations decisions automatically).

Optional federated learning: customers can opt‑in to share encrypted model weights (never raw data) with differential privacy; aggregated weights are redistributed, so everyone benefits from better models without sharing data.

What’s intentionally not included

No calls to OpenAI, Anthropic, Gemini, etc.

No need to upload data to a vendor cloud or “AI API gateway”.

No chat front‑end pretending to be a decision system. The whole stack is designed to keep regulated enterprises comfortable: GDPR native, EU AI Act‑oriented, zero‑knowledge architecture, and the option to run in offline or air‑gapped environments.

Why this might be interesting to YOU:

If you work in a large company, you’ve probably seen AI pilots die because security/compliance blocked sending data to LLM vendors. This is built specifically to avoid that conversation entirely.

Architecturally, the Intelligence Bus is a bet that many small, specialized models, orchestrated with explicit events, beat “one big model with prompts” for structured business decisions – especially when you need explainability and stable behavior.

It’s also an experiment in “old school” ML at scale in an LLM‑obsessed moment: the platform leans heavily on structured data, time series and tabular ML rather than generative text.

> I think it is insane to expect that when you offer something for free (or very cheap), and it requires work and patience, that most people will follow through.

Just look at gym memberships. Apparently over 2/3 of people never use it and only about 20% use it regularly. Are the gyms also to blame for that? I don't think so.

If you can, do not expose ports like this 8080:8080, but do this "192.168.0.1:8080:8080" so its bound to a private IP. Then use any old method expose only what you want to the world.

In my own use I have 10.0.10.11 on the vm that I host docker stuff. It doesn't even have its own public IP meaning I could actually expose to 0.0.0.0 if I wanted to but things might change in the future so it's a precaution. That IP is only accessible via wireguard and by the other machines that share the same subnet so reverse proxying with caddy on a public IP is super easy.

Hi, the "author" and OP here.

I posted it 4 days ago here but it got zero attention. Surprisingly, the recovery process from Yesterday's outage of HN, had it reposted, and I was surprised to see it this morning in the front page.

here is the story of this post

I have just started studying math in October, and my first course is linear algebra.

I have read too many introductions to complex numbers that follow the same script:

"Mathematicians needed to solve x^2 = -1, so they invented i, and despite calling it imaginary, it turned out to be useful..."

Then comes the complex plane, and everyone nods along, pretending they understand why we’re drawing circles when we started with algebra.

I never bought it. Something felt wrong.

So, last week I took a break from my lecture/recitation routines to write down everything I know about the topic, fill in the gaps, and search for the real answers.

While I was working with the LLM to answer the questions to myself, at the end of the day, it felt like sharing it might be beneficial, so that took another two days of me fighting the LLM to control it in place and have it focused on the historical facts and chronological order of events.

When my search led to Cardano's actual book, and pages in discussion, I was so thrilled, naively thinking others will find it useful as well. Apparently, everyone want to start an "AI-STARTUP", but refusing to get involved even in reading if AI was involved in the process.

I am open and clear about the use of AI and had no intention of claiming "discoveries" whatsoever.

This is in fact my first "math" related post I put out online, and I get the criticism with open arms, as long as they related to the math and history facts (and there are issues spotted which I may take the time to correct).

The Oil Well analogy (and other spicy terms) is not an AI's but mine, see, at a certain point, I was drinking coffee in my balcony, here in Abu Dhabi, over looking the sandy horizons, and while thinking about a discovery of new layer of numbers, the association with the Oil wells was inevitable.

here is a comment I have written by hand, no AI/LLM involved whatsoever.

thank you for reading.

That's a wrong way of using AI in peer review. A key part of reviewing a paper is reading it without preconceptions. After you have done the initial pass, AI can be useful for a second opinion, or for finding something you may have missed.

But of course, you are often not allowed to do that. Review copies are confidential documents, and you are not allowed to upload them to random third-party services.

Peer review has random elements, but thats true for all other situations (such as job interviews), where the final decision is made using subjective judgment. There is nothing wrong in that.

The fact that HN does not work in exactly the same way as the horrid platforms out there that automagically surface things that make neurone in your head scream "click that thing! click it! look! LOOOOOOK!", does not mean your brain doesn't treat it the same way.

This isn't unique to this technology: books with interesting titles and covers sell better than books with boring titles and covers, even if the latter has more interesting content.

I think what makes HN a little different is that a lot of places we might congregate online only exist for the flamebait, or are specifically built around engagement metrics to serve DAU/MAU numbers and advertising asks. You just happen to take a bit more chance on here than you would anywhere else, and that's absolutely 100% a good thing.

If there are controllable inputs that skew you to one side of the variance, I hope the moment someone discovers them, they are shut down - otherwise this place just becomes another hell-hole.

So DB Pro is a local desktop database client for managing your databases and data. Prisma ORM it won't replace, but Prisma's browser-based data browser, yes it will absolutely replace that. It's not a replacement for Supabase, it works alongside it, if that answers your question?

I'm planning to extend DB Pro into much more than a database manager though, letting you build dashboards, workflows and workbooks.

(Show HN?) Here is another attempt at providing intuition on complex numbers, the multiplication rule in particular: "Why does complex multiplication have to be the way it is?" https://gregfjohnson.com/complex/

I find that the easiest intuitive on-ramp to complex arithmetic is to start with compass headings: "Oh that nice coffee shop? Go two blocks north and then a block east." Numbers come with any direction on the compass, not just "east" and "west". It turns out that it is pretty easy to intuitively justify multiplication by a scalar and addition of complex numbers, but multiplication is harder. A great way to get a feel for multiplication is to consider the equation "(x+1)(x-1) = x*2 - 1". Then, substitute "i" for x. The left-hand side is (intuitively) on a circle of radius 2 centered at the origin, and the right-hand side is on a circle of radius 1, where the circle is shifted horizontally so that its center is on the real line at -1. There's only one place these two circles meet: -2 on the real line.

This question seems very strange, because it’s really not difficult to understand how it works. You submit, people vote if they like it, but mostly ignore it, and occasionally flag it. Stories that generated interests rise, sometimes to the point where they end up in the front page. Stories that generate too much unwanted interest (e.g. that look too much like flame wars, or like never-ending discussions that go nowhere) sink to the bottom. There are corner cases and you won’t get the exact algorithm, partly because human moderators intervene as well.

If there is one thing to note, it’s that obvious self-promotion is not good. Technical details are more interesting than sales pitches.

Good candidates are not universally good, they are good for you after hire.

One of the best business analysts I worked with (also a profession, mind you) was almost fired when working under an old, grumpy and clearly underskilled one.

I was hired once without interview into a unicorn, was loved by colleagues but hated the work, the business and the industry, then left rather quickly.

See? There are mismatches and unknown unknowns, not just bad or good developers.

Our L1 defense is actually incredibly good. A human will undergo about 10^16 cell divisions over the course of their lifetime. Around 10^3 to 10^6 of those divisions will result in a mutation that gets past the L1 defenses and need to be eliminated by the T cells. It's not generally easy to make dramatic improvements to something with a 99.9999999% success rate.

The immune system is pretty good too, which means any given improvement to the replication system is, all else being equal, probably going to prevent mutations the T cells would already handle. If you need to do the research to figure out what's getting past the immune system anyways, and improving the immune system is lower hanging fruit, it's the logical place to start.

Ultimately most of these decisions come down to economics and not mustache twirling villains. The banality of evil.

Simplest "bad" reasons are the wealth of the patients. Malaria, river blindness, guinea worm, etc are terrible diseases that mostly impact poor people out of sight from Western eyes. Spending $X billion developing a drug for a population that can barely afford to feed themselves is not going to make a financial return on investment.

[Laughs nervously]

I bet that this isn’t an exaggeration. Being highly-ranked on HN can probably give a startup a huge advantage, in the hype department.

I guarantee that LLMs are currently being feverishly trained on HN front pages, for the last few years, and we’re gonna be seeing “link farm” sites, specifically designed to rank high on HN.

I enjoy it here. I don’t hang out on any other social media, so this place gets a lot of my time (I’m writing this right now, as I’m working up some tired, to go back to sleep). I’ve spent my entire life, hanging around people that intimidate and inspire me, so this place feels like home.

If it turns into a Dead Internet site, I’ll probably pack it in. I have left a number of sites, over the years. It would make me sad, as I’ve lasted longer here, than anywhere else.

Most of my karma is from comments, not submissions. I like to engage.

And most of it was struck down immediately, with the dismantling solved by the most serious threat of packing the Supreme Court by the President and his party

what stands out to me is that this President is written about favorable in our history books despite that plan being far more egregious and unprecedented at the time

in any case, the court shifted its tune as a compromise not as a matter of actual opinion of the constitution

and like I previously wrote, everything else was just hard to challenge at all, unless you are a President suddenly trying to fire some folks

the US advancing from a backwater to an economic powerhouse is great! I wonder if we can do it another way without leaning on the Interstate Commerce clause to regulate all facets of American life

A great take, and thanks for your all hard work dang.

Yesterday the top comment on two stories I went to discuss had deep and meaningful content, before the last line which was a "and I talk about this stuff all the time on my newsletter [link]", and I was conflicted. Same poster each time.

The poster had done the HN thing: responded with thoughtful examination of TFA, unique and interesting insight, and I don't feel it was AI generated.

And then they marred it. They pushed something just slightly out of context. Not entirely, just a smidge.

I hope we can keep an eye on that sort of thing around here, it feels like it could slide into something...

I know companies that are posting vacancies that currently don't exist in order to keep good candidates on the hook. They tell the candidate that we should keep in touch for when the company is ready to hire them.

I am not sure if it's bad or not. It's true that it kinda wastes the candidate's time. In some cases though, the candidate is so good that the company will create a position just for them.

Writers.

Money. A spot as US citizen to get into startup school.

Money. An investment from a noble mind to another noble mind.

Money. Pass information to fellows at YC (who are from a different domain, see YC as a cool place) they crowd and promote (seems organic)

Money. Well, then the product or the tech fades, because its a bloatware.

They retry the same thing again with next batch of people. Keeps the forum running. The maintainers get retired or really tired.

Readers. I have seen this one before. Reader. Well, now, you are old

This is so cool! As someone who loves trying out new restaurants I need to ask: why would I go with you guys instead of going to the restaurants myself with a friend or partner? Looking around your website it seems to me that there's very large attendance, which in my mind means generally less focus on the food itself. Do you think one of the main factors is meeting new people/the sense of community? Anyway good job! I'm not sure what your margins are but it's probably more than 500/month! Congrats!

> how does that work as a growth indicator, are there any known organizations that track your growth based on how many job postings you do, and then use that data to indicate your growth?

As a wild guess this may be part of the story a company tells itself. Every individual and company needs to tell themselves a nice "story" to feel good about themselves. In case of a company "damn, look how many jobs we're posting, we're growing and doing great" is a nice story to tell. Yeah the owners/manager know it's fake, the people writing the post know it's fake, people receiving applications also know it's fake, yet it still works. On paper officially they can tell each other how great they are doing. This is more likely how a large company would operate.

Another, more positive perspective from a small company I worked for is "ABH" (Always be hiring). That means always post jobs, and continue interviewing, because you might find an exceptional engineer for whom you'd make an exception and hire them. But at least in our case it was always an honest effort every time to sit down and evaluate the candidates, pay them to visit and interview face to face and such. It wasn't a game it indeed took quite a bit of effort on our side.

For years I thought that Hacker News has no moderators. Apparently it does, but they seem to keep a low profile. I have no idea what their protocol is and I don't see any help menu that mentions them.

I found out, the other day, that if you post too many comments in too short a time (also undocumented) your final comment is deleted (sorry, you just lose it) instantly with a somewhat snarky message about how you post too much.

I am a little mystified about what community Hacker News serves. It doesn't seem to be the kind of hackers I grew up with (fiercely skeptical, a la 2600 magazine), because, as one example, skepticism about AI or self-driving vehicles is generally downvoted.

Not so much Hacker News as Next Shiny Toy News.

Even so, I know of no better way to discover interesting tools and trends than Hacker News.

"The measure does not allocate any initial city dollars, a move that may have helped secure support from the board's moderates after repeated years of city budget shortfalls. Instead, the ordinance establishes a framework to receive future contributions - whether through city appropriations or private donations."

"Walton acknowledged funding remains the central challenge, but expressed optimism about tapping foundations, corporations, and individuals to support the effort."

Is the $5m an upper limit?
