Just don't try putting something convenient in between, at least that's what my adventures in TB4 taught me: displayport from a TB port works fine, even when DP goes to a multiscreen daisychain and the TB does PD to the laptop on the side, but try multiscreen through a hub and all bets are off. I think it's the hubs overheating and I've seen that even on just 2x FHD (Ok, that one was on a cheap non-TB hub, but I also got two certified TB4 hub hubs to fail serving 2x "2.5k" (2560x1600). And those hubs are expensive, I believe that they all run the same Intel chipset.

I was brought up on the refrain of "aren't computers silly, they do exactly what you tell them to do to the letter, even if it's not what you meant". That had its roots in computers mostly being programmable BASIC machines.

Then came the apps and notifications, and we had to caveat "... when you're writing programs". Which is a diminishing part of the computer experience.

And now we have to append "... unless you're using AI tools".

The distinction is clear to technical people. But it seems like an increasingly niche and alien thing from the broader societal perspective.

I think we need a new refrain, because with the AI stuff it increasingly seems "computers do what they want, don't even get it right, but pretend that they did."

For the past few weeks, I've been working on one of the coolest things I've ever pushed to production (in my opinion, of course): a LeetCode-style platform for system design.

I've been writing about system design for a while now, and I genuinely love the topic (I talk about it weekly on my blog https://olucasandrade.com). I always wanted a tool to practice it without having to hunt down a billion references across the internet.

Every tool I found was either paywalled for the basics or completely abandoned. So, I built my own, and I have no intention of letting it go. I believe this project has the potential to build a really great community. That's why I decided to "open-source" the entire platform. It's 100% open on GitHub, and I'm already creating issues for the next planned evolutions.

How this can help you:

The idea is simple: just like LeetCode, you can submit your solution (with a diagram + textual explanation), and you can view and interact with solutions from others. No favoritism here—I truly believe there's no better way to prepare for an interview or just sharpen your skills.

I don't plan to fully "productize" this until I hit my first major goal, so feel free to play around as much as you want, and please let me know if you find any bugs.

How you can help me:

First and foremost, dropping a star on the repository (https://github.com/olucasandrade/systemstudio) is a huge boost. That alone is massive support.

But if you want to help on a deeper level, feel free to open issues or even pull requests to add new features or work on existing ones. Honestly, the potential of this platform is not something I have enough bandwidth to explore alone. Finally, spreading the word is also a big help. I want this to reach as many people as possible who need it.

Cheers!

The link to the app is: https://systemstudio.app If it gets some traction, I'll share the next steps that I plan.

It will not.

One (of many) issue is that this has no bearing on other regulatory regimes. So, sure, the FDA approves of the drug/device/thingy because the AI got lost and no one is checking what it's saying. But Canada's CFIA doesn't because they are still using real people or centaurs ( people + AI, but I'm not 100% sure so don't quote me on that ).

That makes it so that you can only sell the drug/device/thingy in the US and some other countries that blindly follow US FDA (mostly poorer nations with very small markets and a lack of legal recourse, they'll just turn to the EFSA/EMA).

Which fine, but that is not the bet that these large companies made about a decade ago when it came to whether or not this drug/device/thingy would be worth it to pursue. These big drugs need to pay off all the failed research with international sales. Same is somewhat true with devices (mostly internal these days). These big drug makers want stability. Profits are fine, but revenue is just as important as these pipelines are sooooo long and soooo fraught. The human body is just too variable.

The tariffs and all the monkey business with this admin is very much not good for the US when it comes to these large drug/device/thingy makers. Chaos is not good for business. They have all learned that Donny and his ilk (per the article here) do not keep their words when it comes to corruption. They do not stay bought, they are not stable.

We're already shedding jobs here in favor of moving to the EU. Yes, not India or China, but the Baltics mostly (inside Schengen zone). We lost 10 people with jobs opening up there (same day) just this last week. The EU is stable in the eyes of my very own bosses.

It's verifier law.

Coding agents are useful and good and real products because when they screw up, things stop working almost always before they can do damage. Coding agents are flawed in ways that existing tools are good at catching, never mind the more obvious build and runtime errors.

Letting AI write your emails and create your P&L and cash flow projections doesn't have to run the gauntlet of tools that were created to stop flawed humans from creating bad code.

Hey HN,

I'm the solo founder of Korrero. I built this out of my own frustration. On my previous projects, I was constantly getting pulled from core dev work to handle "simple" content updates for marketing (like changing text on a promo banner). It was a huge productivity killer.

So I built Korrero: a headless CMS focused only on notification content. The idea is to be a "peace treaty»: 1. For Marketers/PMs: An intuitive no-code UI to create, schedule, and manage all dynamic content (banners, alerts, etc.). 2. For Developers: A simple API/SDK. You set it up once, and never get a content ticket again.

It's built on a modern stack: Next.js/Tailwind for the lander, React/MUI for the admin panel, and an Express/Prisma/Postgres backend.

We're also launching on Product Hunt today, but I'm here because I'd love the technical feedback from the HN community.

Is this architecture overkill? Is this a pain point you've also felt? I'd be grateful for any thoughts or brutal feedback.

Steam getting a 30% cut is certainly less objectional that Apple getting 30% because they've locked other people out of selling on iPhones.

On the other hand, that Steam taking as big a cut as Apple can claim because of their unfortunate practices isn't great.

Generally, the smallest indie creators, who aren't really likely to benefit from organic discovery on Steam, seem to priority selling on itch, which, by default, only takes a 10%, despite doing all the work you mention.

That Steam seems to have a marketplace monopoly based on network effects, and this allows them to claw money from all but the largest and smallest game developers is not something they have a strong right to claim to morally, and something society would benefit from doing away with. It appears that 72% of game devs feel that way too.

So, to answer your question, for me, two thirds of Steam's revenue seem unfair.

Since Llama 2, the models have been commercially licensed under an acceptable use policy.

So you're able to use them commercially as you see fir, but you can't use them freely in the most absolute sense, but then again this is a thread about restricting the freedoms of organizations in the name of a 25-year-old law that has been a disgrace from the start.

> contributing to degradation of the Web for humans

I'll be the first to say that Meta did this with Facebook and Instagram, along with other companies such as Reddit.

However, we don't yet know what the web is going to look like post-AI, and it's silly to blame any one company for what clearly is an inevitable evolution in technology. The post-AI web was always coming, what's important is how we plan to steward these technologies.

It's weird, but the pain of moving to a whole new language seems less than the pain of using one of these language subsets. I guess it might be because of "loss aversion": we dislike losing something we have more the value we put on gaining it. In a new language each newly added feature is a gain, but in a language subset you're always encountering things you would have in the full language. So no matter how good the rational case is, there is a bias against them. I can't think of a successful one actually - anyone?

> I guess you have no experience with assembly lines?

I've spent a few weeks on one, so not zero, but not a lot.

Note that I simplified greatly a real assembly line, and there are lots of different lines with different configurations. Nearly everything is multiple lines. There are often buffers along the way so that you can get ahead of the line by a little (or if you need to use the restroom the line continues). Sometimes there are two people in a station with the understanding that if both are perfect they are 80-90% busy (or some such number), but if someone is slow the other can help up. Lines often go slower than possible because of safety. There are likely more issues, but there is a point where the line is waiting on the slow person.

With the above in mind, what am I missing?

Patents and copyright are both IP. Feel free to replace “copyright” with “IP” in my comment. Do you not agree that IP laws are related to the explosion of innovation and creativity in the last few hundred years in the Western world?

Furthermore, claiming “X is not natural” is never a valid argument. Humans are part of nature, whatever we do is as well by extension. The line between natural and unnatural inevitably ends up being the line between what you like and what you don’t like.

The need to eat is as much a natural law as higher human needs—unless you believe we should abandon all progress and revert to pre-civilization times.

IP laws ensure that you have a say in the future of the product of your work, can possibly monetise it, etc., which means a creative 1) can fulfil your need to eat (individual benefit), and 2) has an incentive to create it in the first place (societal benefit).

In the last few hundred years intellectual property, not physical property, is increasingly the product of our work and creative activities. Believing that physical artifacts we create deserve protection against theft while intellectual property we create doesn’t needs a lot of explanation.
Show HN: I built AI twins from LinkedIn and CRM data to simulate real B2B buyers
by resonaX | 2025-11-05 14:05:03+00:00
I’ve been working on resonaX — an experiment to see if we can simulate real B2B customers using AI.

The idea: instead of sending surveys or running A/B tests, what if marketers could ask questions directly to an AI twin of their ideal customer — built from real data like LinkedIn profiles, CRM notes, and behavioral insights?

Each twin captures that customer’s role, pain points, buying triggers, and communication style. You can then ask:

“Would this headline make sense to you?”

“Why would you hesitate to book a demo?”

“What would make this offer more relevant?”

Under the hood:

LLMs + embedding models fine-tuned on buyer language

Real-world inputs (LinkedIn data, optional CSV uploads)

Lightweight feedback layer to validate responses

70+ beta testers are using it to test messaging and GTM ideas before launch.

Would love feedback from HN:

How might you improve the data ingestion layer? How can I simulate a focus group? How can i combine data to create a digital twin of a post like VP of Marketing (broad as some users are demanding not testing with just one profile but a combination of atleast 10)?

Any ideas to make the twin modeling more reliable over time?

I work in corporate finance and these issues are certainly present. However, they are almost always known and determined low priority to have a better process built. Finance processes are nearly always a non priority as a pure cost center/overhead there’s not many companies that want to invest in improving the situation, they’ll limp along with minimal investment even once big and profitable.

That said, every finance function is different and it may be unknown to them that you’re being asked for some data multiple times. If you’re enduring this process, I’m of the opinion you’re equally at fault. Suggest a solution that will be easier on you. As it’s possible they don’t even know it’s happening. In the case provided, email to all relevant finance people “Here’s a link to a shared workbook. I’ll drop the numbers here monthly, please save the link and get the data directly from that file. Thanks!” Problem solved. Until you don’t follow through which is what causes most finance people to be constantly asking for data/things. So be kind and also set yourself a monthly recurring reminder on your calendar and actually follow through.

Sadly, it doesn't mention the related (and equally-wonderful) Whole Internet User's Guide and Catalog: https://www.computinghistory.org.uk/det/16352/Whole%20Intern...

Before web search engines became a thing, "searching the net" meant either fiddling with WAIS/Veronica (which searched only titles, not content), sending mail to your local "weirdy beardy" Unix guru - or getting a bus into town, heading for the nearest bookshop, and spending half an hour flicking through their sole copy of WIUGC.

The latter course often turned out to be by far the most productive...

Unfortunately, it doesn't help.

Almost any digital camera RAW format is TIFF inside. And you can see how much kludges good metadata library needs to read all of them: offsets from the IFD, offsets from beginning of file with or without header, offsets from fields in IFD, etc, etc, etc. You take TIFF, you change header to make your format, and then you cannot implement this TIFF properly!

Even DNG (which is tiff inside) is mangled by camera firmware authors!

What's the chance this event happened as recorded in popular memory? The inscription dates to 1284, but the earliest mention according to the article is 1384, 100 years later. On a symbolic day no less. The plaque, where 1284 is inscribed, is on a house dating to the 1500s.

It seems much more plausible that e.g. children emigrated as adults to another region (as mentioned in the article) and the old-timers who stayed behind lamented the 'loss of their children' so to speak; when the history was recorded in town records, it's unlikely that any of these old-timers or children were around. Hundreds of years of historical layering, where the most interesting version of the story is the one that is reinforced likely explains the mythological nature of the tale.

But what do I know? I suppose it is curious.

Everything is now about verification.

AI may be able to spit out ann excel sheet or formula - But if it can’t be verified, so what ?

And here’s my analogy to think about the debugging of an excel sheet - you can debug most corporate excel sheets with a calculator.

But when AI is spitting out excel sheets - when the program is making smaller programs - what is the calculator in this analogy ?

Are we going to be using excel sheets to debug the output of AI?

I think this is the inherent limiter to the uptake of AI.

There’s only so much intellectual / experiential / training depth present.

And now we’re going to be training even fewer people.

At the end of the day I /customers need something to work.

But failing that - I will settle for someone to blame.

Brenda handles a lot of blame. Is OpenAI going to step into that gap ?

Not always:

If you don’t automate it:

1a) your company keeps you hanging on forever maintaining the same widget until the end of time

OR

1b) more likely, someone realizes your job should be automated and lays you off at some point down the road

If you do automate it

2a) your company thanks you then fires you

OR

2b) you are now assigned to automate more stuff as you’ve proven that you are more valuable to the company than just maintaining your widget

————

2b is really the safest long term position for any employee, I think. It’s not always foolproof, as 2a can happen.

But I’d rather be in box 2 than box 1 any day of the week if we’re talking long term employment potential.

The DC-10 was a rushed programme to avoid Douglas being frozen out of the 1970s widebody market by Lockheed and Boeing.

Similarly, the MD-11 was a cost-restricted update of the airframe to avoid McD being frozen out of the 1990s widebody market by Airbus and Boeing.

McD management wouldn't fund the more ambitious four-engined MD-12, so the trijet's fuselage was stretched and aerodynamic tweaks applied.

The MD-11 never met its performance targets and heralded the end of the Douglas commercial line. It was fairly quickly relegated from pax to cargo service where it has a good payload but little else to commend it.

I see where you are coming from but in my head, Brenda isn't real.

She represents the typical domain-experts that use Excel imo. They have an understanding of some part of the business and express it while using Excel in a deterministic way: enter a value of X, multiply it by Y and it keeps producing Z forever!

You can train AI to be a better domain expert. That's not in question, however with AI, you introduce a dice roll: it may not miltiply X and Y to get Z... it might get something else. Sometimes. Maybe.

If your spreadsheet is a list of names going on the next annual accounts department outing then the risk is minimal.

If it's your annual accounts that the stock market needs to work out billion dollar investment portfolios, then you are asking for all the pain that it will likely bring.

Yes, subscribing outside the app does avoid the cut. Which is why you can't subscribe to spotify in the iOS app, you have to open a browser: https://support.spotify.com/us/article/cant-subscribe-to-pre...

Until this year, Spotify couldn't even tell you in the iOS app that you could pay for premium: https://newsroom.spotify.com/2025-05-01/following-landmark-c...

This meant in apple music, the user could open the app and it would work including paid features.

In spotify, you could open the app and it would tell you "You can't subscribe here, sorry" and couldn't even link you to a webpage you could subscribe at.

I'm certain a non-zero number of users couldn't understand what to do with that apple-approved error and gave up.

Maybe there's a reason that apple lost in court for that one.

"Thinking mode" only provides the illusion of debuggability. It improves performance by generating more tokens which hopefully steer the context towards one more likely to produce the desired response, but the tokens it generates do not reflect any sort of internal state or "reasoning chain" as we understand it in human cognition. They are still just stochastic spew. You have no more insight into why the model generates the particular "reasoning steps" it does than you do into any other output, and neither do you have insight into why the reasoning steps lead to whatever conclusion it comes to. The model is much less constrained by the "reasoning" than we would intuit for a human - it's entirely capable of generating an elaborate and plausible reasoning chain which it then completely ignores in favor of some invisible built-in bias.
