It's not the articles themselves. It's the quality of the commentary that comes from them. IMO these highly charged topics are very corrosive to the culture of a site. The people that post the hyper emotional comments on these posts and get rewarded in upvotes start doing the same thing throughout the site. Also in my experience if I post a low effort political comment I get much more karma from the crowd than a high effort technical post. What does that do for content incentives?

It's my belief that the recent growth in both user count and highly emotionally charged low quality content on this site is directly proportional to the amount of hot button issues on this site. A decent amount of folks use this site as yet another culture war front.

IMO these kinds of discussions need much, much more moderation than HN does to be productive. That's not a knock on HN moderation, it was never meant to be a structured debate platform. But taking a lightly moderated site and inundating it with hot button high emotion posts will not go well.

Very funny read from the MBA set when the same collapse is happening in software itself. He's saying MBAs are going to have to shift to data analysis and product design roles, as if those aren't being eaten by the very same processes.

But I don't say this to belittle the author, I just mean funny in how people are all grasping around the same elephant (https://en.m.wikipedia.org/wiki/Blind_men_and_an_elephant). I don't claim to have special insight here, just noticing that this is happening across many diverse professions. My personal theory is that we reached the point of diminishing returns of what can be built and effectuated via software or people management and at some point an economy can't bear the dead weight of people pulling down six figure salaries by moving some javascript or PowerPoint slides around, while the base of the economy (industry, farming, energy production, transportation) dies from lack of investment.

And if you are using a newer Perl they sometimes add features that aren't enabled by default unless you opt-in with a 'use v5.38' style declaration.

If you want those features on in your one-liner you can use -E instead of -e

perl -pi -E '...' file.txt

(I used to need this long ago when I wanted to use the then-new "say" in my one-liners)

If you want to actually measure radon concentration quantitatively what you are describing is not the way. Typically devices simply measure alpha count rates coming from air, radon diffuses very effectively and no filtering or extra flow is necessary. Your technique would show "hey look there is a little bit of something radioactive here" but would be very difficult to turn into a concentration without a lot of extra complicated steps.

Agreed. I think an underappreciated aspect of choosing a script VM in the space Roblox is in (user-generated content where scripts are content) your product is at the mercy of whoever controls your scripting implementation.

The scripting engine is an integral part of your product, and you need to "own" it end-to-end. Any bugs that creep into new versions of your scripting engine, any API breakage or design changes that impact your usecase are things that you are responsible for. Roblox owns the entire toolchain for Luau, and it's relatively small compared to the set of libraries required to compile to and execute WASM in a performant way.

The nuances of your typical JITing WASM runtime or V8 are pretty hard to learn compared to a simpler VM like Luau, it's a big reason why I've used Luau in my own projects.

Liability and access rules in the US vary by State. For example, Maine allows open access to private land by default (owners have to post to prohibit access) and protects owners from liability (as long as they don't actively create hazards). Some coastal states have public-right-of-ways along the shore... there's a lot variation, as always.

Fun to read about the other systems and considerations in this thread.

1. realtime features, timeplus can help build realtime features with realtime data processing capabilities

2. realtime data context, for AI LLM that need fresh data context to do a better job, timeplus can be used to process and service those realtime data for it

3. realtime inference, in those cases where user want to do realtime inference, leveraging those UDF, user can combine the realtime data with model inference in one single box, greatly simplify the overall ML architecture

Feels a lot more like power was concentrated again and the bottom line managers and middle managers are being cast out.

This aligns with corporate history in America going back decades.

Like how many of these people in the “management” class are actually managers in the sense that they are given agency over resources and how they are deployed vs supervisors who are just there to make sure the real manager’s(usually a Director or VP) plan is executed or alerting up the chain if it isn’t?

I had more say as a supervisor in a deli at age 20 when I picked what shifts people got without the need for any sign off than I have ever had in the tech industry with the word “Manager” in my title. You’re ostensibly in charge of raises and promotions but in reality you are only advising on those decisions and your vote only matters as much as your real manager cares about your opinion

I'm thinking of people who bought an Occulus Rift, which Meta then purchased and then forced people to associate a facebook account with it which they could then ban causing you to lose access to the hardware (and any games you purchased). A strong incentive to use the facebook account as little as possible since making a throwaway facebook account is now such a PITA. Infuriating since it was a bait and switch on an expensive piece of hardware. I guess the only winning move was to sell the device to some other sucker the moment the facebook purchase of Occulus was announced.

Don't worry this requirement was removed. Now you just need a Meta account which is totally different!

Yeah, but the government would have to prove it in court, which is hard and takes a long time. As long as there are a bunch of other people doing it chances are you will die of old age before law enforcement does anything about it. Lots of rich people crime works this way. Make it hard enough to prosecute and you can get away with it, especially when you can afford to hire good lawyers.

That's reasonable and personally I hate it when all the helpful details I need are buried in Slack history. But also it's a lot more effort. When someone has an immediate question they need help on, real time chat is an appropriate place to get help.

It takes additional effort and overhead to then go capture the pertinent details that exchange and write them in a wiki. With infinite Slack history you get a janky high noise knowledge base for "free". Huge downsides of course, but clearly it's a very popular approach.

My general experience with things like this from Google is to assume that this is at least one big step behind what they're doing now internally. Taking a position on how useful one finds this today effectively insulates from thinking more seriously about what could be done. If taken from a perspective of "what hints are laying around in this blog post or scientific articles about what's possible?" it's probably more effective use of time if you're going to invest time in reading it.

As an example, as you're reading it, try posing a few relevant counterfactuals.

The data and searchability is slacks main selling point. A lot of people don't get that.

I've been using slack for years, since they didn't have video chat or any of that.

There are countless chat apps, including IRC. Slack's offering is that I can find messages or files on some subject from years ago with little effort in a matter of seconds. The history is the product IMO. The free 90 day version is worthless IMO, and barely better than IRC etc.

Slack's name is supposedly derived from "Searchable Log of All Conversation and Knowledge".

I have been using Supermemo daily for almost 20 years, and I have basically stopped trying to sell people on the idea. When I explain it to them, they agree that it is a good idea, but very a few people can truly follow through in the long-term. Yes, SRS is basically a gym membership that most people will stop using after Jan 3, I like that metaphor.

I was wondering what was going on, because Orange Pi only sells to distributors, not direct to customers.

Amazon only has a single listing for any given product, and all distributors, whether authorized or not, are under the same listing. When there's more than one distributor, you can choose which one to order from, but the buy now button follows a default.

If it isn't too late, I would highly recommend disputing through Amazon, as disputes are the only way Amazon addresses problem distributors. Many know how to game the system, so if you communicate directly with them, they will try to delay you until after the dispute period has ended.

This might be slightly of topic but this article mentions the stat that keeps going around that refutes productivity gains given by LLM’s, but honestly I think this is because this is reported by companies that are either measuring time to deliverable completion, or value in dollars generated by their workers using the technology.

They always seem to miss another metric, saved human brain power. My experience hasn’t been that I can complete tasks faster from go to woe, it’s been that they’re far less mentally taxing and I can do other things whilst the ai churns some of the tedium away. When I’m feeling real tired, it’s a lot easier to review ai code than write my own from scratch. As any writer will tell you, editing is easier than writing from a blank page.

A good analogy might be that I can vacuum the house way faster than my robot vacuum can, probably in less than 1/3rd of the time! But letting the robot do it is still way better for quality of life and also it frees me up to do other things. This has been the true gain from using coding LLM’s in my lived experience.

I got this with a very short and basic prompt, it lets the user track blood sugar and ketone levels.

It worked really well, and it was very fast, especially considering that it is on the front page of HN. Congrats, very cool project

I’m not sure this approach is the right one, but the problem resonates with me.

I vividly remember hitting some blocker (7th grade chem, 4th grade reading, 2nd grade dinosaurs), where I had a question that the teacher dismissed.

My mind was stuck (blocked) as it couldn’t get past the question I had, and in a public school setting, it wasn’t worth the time for the teacher to dive down the tangent (or they simply weren’t prepared).

My hope for LLMs in education, is that they can supplement traditional curriculums such that students can go “off the rails” while still being nudged back to the desired outcome.

- How do we know electrons “spin”?

- Why does that word behave differently than others (in English)?

- How big is a sauropod compared to a blue whale?

I’ve found that on my own journey through education, it’s these sparks of interest that drive towards deeper understanding, rather than surface level rote memorization.

TFA says: “What if students had the power to shape their own learning journey?”

In the context of nonfiction/textbooks, this is already possible!

I didn’t read “How to read a book”[0] until high school, but it opened the world for me on another silly blocker I had, which is that material should be consumed start to finish.

Hopefully with “AI” more students will learn that there are many paths towards understanding the world, and not just the curriculum in front of them.

If you can't discern what good answers look like to the questions you're asking, you're not asking the right kind of questions.

Asking the right kind of questions is a genuine skill.

It applies to every domain of life where you are at the mercy of a "professional" or at the mercy of some knowledge differential. So you need to be a good judge of whether the answers you're getting are good answers or bad answers.

For FFTW the showstopper was GPL license. For IPP, 200 MB of binary dependencies, also I remember when Intel was caught testing for Intel CPUs specifically in their runtime libraries instead or CPUID feature bits, deliberately crippling performance on AMD CPUs. I literally don’t have any Intel CPUs left in this house. For cuFFT, the issue is vendor lock-in to nVidia.

And the problem is IMO too small to justify large dependencies. I only needed like 200×400 FFT as a minor component of a larger software.

Like what exactly? As far as I can tell, the drug discovery is fizzling out, so it's not talked about much. Toxicity, for one, is a big problem, and the AI is not going to tell you whether the new drug it just concocted is suitable for humans or not.

Small model solves an easy problem; big model solves a challenging problem. I wouldn't call those problems; they are more like invented puzzles. Perfect match for the AI marketing department to "solve".

Thanks for stopping by to comment!

I'd love to see some good examples of those bugs you referred to, in order to get some more context.

Is the intent of the second form to evaluate only once, and cache that answer to avoid re-evaluating some_expr?

When some_expr is a simple variable, I didn't think there was any difference between the two forms, and always thought the first form was canonical. It's what I've seen in codebases forever, going all the way back to C, and it's always been very clear.

When some_expr is more complex, i.e. difficult to compute or mutable in my timeframe of interest, I'm naturally inclined to the second form. I've personally found that case less common (eg. how exactly are you using nulls such that you have to bury them so deep down, and is it possible you're over-using nullable types?).

I appreciate what you're saying about nudging developers to the most correct pattern and letting the noise fade away. I always felt C# struck a good balance with that, although as the language evolved it feels like there's been a growing risk of "too many different right ways" to do things.

Btw while you're here, I understand why prefix increment/decrement could get complicated and why it isn't supported, but being forced to do car.Wheel?.Skids += 1 instead of car.Wheel?.Skids++ also feels odd.

Offensive how? "Developing" and "things aren't so bad" are offensive because they obfuscate imperialist relations. That's the position of the theorists who use "Global North"/"South", anyway. https://en.wikipedia.org/wiki/Global_North_and_Global_South#...

What do you mean by discriminatory?

Salespeople usually worked with Salesforce in other companies, and some of them are even familiar with the dozens of low-code, no-code tools that you can use with Salesforce. All of them making the data model absurdly worse than what it already is.

Sales and marketing executives are usually the most hostile stakeholders an engineering department may have (tip: Sometimes Legal and Compliance are your best allies when in a fight against Marketing and Sales), they absolutely hate engineering because they are absurdly focused on the short run.

Give them Salesforce, Office 365, some connectors and some no-code tool and they poke holes the size of the Titanic in your security, but they don't care, because they want their brilliant ideas implemented now, and salesforce and excel let them do whatever they please now.

Seems very similar when Microsoft invested in Apple back in the day when Apple was about to die. Their concern was that they would be the only one OS company standing and be defacto a monopoly and regulated such. So, it was a away to keep your 'weak' competition alive just enough not to make you the sole provider.

Steve Jobs was able to turn around Apple in such a fashion that they become even bigger by letting go of the PC market and going mobile.

Not just "off the air," either. I'd be surprised if 1% of Kimmel's viewership receives the show over the air.

The distinction is vital. The FCC's stewardship of the public airwaves as a limited natural resource is the only reason we granted them this extraconstitutional power in the first place. When the airwaves aren't actually involved, the FCC should have no say whatsoever.

I've been hosting a git service for quite a while now and it's maybe around half an hour per year of maintenance work. It's totally worth it in my opinion, it's so much better on almost every way ... One big reason is decentralization. Full control of data, change what you want, then things like the current npmjs attack show the downsides of having everyone using the same thing, and so much more

It was the only amazon distributor as far as I know.

they were directly linked from the Orange Pi 5 website.

Its their responsibility they direct their customers to dubious distribution systems (IF THAT IS THE CASE).

We should never reward orders or preorders in any fast devaluating area (like electronics) to be reneged after inflation: this would allow manufacturers to post-select a financial path: if less inflation than expected fulfill order, if more inflation than expected renege the deal.

Same in the UK - it is called the Occupiers Liability Act. It's not black and white but the liability is on the Occupier. I know this because I own an area of ancient semi-natural woodland which I'm restoring back to the natural NVC type (basically, oak standards and hazel coppice). As part of my duty I have to go and survey all the boundary trees once every "reasonable period" and after storms or significant weather events. There's some nuance to in the liability I've got when considering the harm to trespassers, but staying on top of duties and having your auditing ducks in a row helps.

It's like exercise equipment.

If you have free weights, a bench, and a place to run, you are already 98% of the way to being a healthy fit human. There is ample information available on how to use those tools.

You don't need a trainer, a $10,000 gym machine, and a $5,000 stationary bike.

Education has gotten so insane with per-student spend, and the results are the same as the kids who had pencils and 10 year old text books.

What if the base of the economy is well-paid power point rangers buying stuff? Because that’s what most of our economy is: consumer spending.

It’s some sort of myth that the American farmer is the core of our economy or something.
Show HN: Nanobot – Turn MCP servers into full AI agents
by smw355 | 2025-09-18 19:46:07+00:00
Today we're releasing Nanobot an open-source framework for building AI agents on top of the Model Context Protocol (MCP).

MCP servers are a great way to expose structured tools, but they’re usually just that—collections of functions. Nanobot makes it simple to wrap any MCP server with reasoning, a system prompt, and orchestration so it behaves like a real agent. Even better, Nanobot fully supports MCP-UI, so agents can pass rich interactive components (forms, dashboards, even mini-apps) directly into chat.

A simple example: if you had a Blackjack MCP server with tools like deal, bet, and hit, you could wrap it with Nanobot to create a dealer agent that knows how to explain the game, guide a player, and render an interactive Blackjack table inside chat.

We built this because we wanted agents that go beyond text and function calls, into actual interactive experiences—something useful for everything from games to e-commerce to developer tools.

Code is on GitHub: https://github.com/nanobot-ai/nanobot

Live demo (Blackjack): https://blackjack.nanobot.ai

We’d love feedback from this community—on the framework, the design, and what you’d like to see next.

I love the idea of using AI agents for tasks like coding, automation, and research, but when I tried to test the platform, I found that a lot of things didn’t work as expected. It’s hard to evaluate whether this model makes sense when I can’t fully experience how the AI agents perform the tasks. Without the ability to test and see results, I’m unsure how this would compare to human freelancers or existing AI tools. It feels a bit premature to gauge its value right now. Looking forward to seeing more functionality and clearer use cases!

> EdTech has the worst returns of any industry in venture capital. Why?

I think this one is fairly simple. Half of consumer spending comes from the top 10% of earners, whose kids we can assume have generally pretty decent educations already. The people who need education help the most don’t have money to spend on it.

The parents who do have money to spend want to invest in tailored education from a human teacher, not cheap, generic scalable technology. So margins will be low.

So if you want to make money, you need to focus on things like enrichment and test/college prep for the top 10%. Helping inner city kids who are 3 grades behind in reading doesn’t print money and VCs don’t want anything to do with that.

Eh we got confused implementing this today.

Basically we severed connection to the public npm registry completely earlier in the week whilst this worm plays out.

Unfortunately there wasn't a way to do this without taking our cached "good" public packages down as well, so we later replicated the good cached packages into a new standalone private registry to be the new upstream.

The bit that was not obvious in the moment but self evident once we realised is that the registry we're using took the copy time as the publish time, and therefore our new 2 week delay is rejecting the copied packages...

So sample size of one, but the registry we're using is definitely using upload time not any metadata in the packages themselves. Good to know the filtering is working.

And this post shows exactly why cluely is such a damp squib destined to fail. Zero substance just grandiose claims that hold no water. They’re spending tens of millions of dollars of investor money “going viral” instead of spending investor money actually building a great product.

Cluely is just some kids larping as founders, the perfect example of the worst of the AI boom, it’s as if the entire thing is AI generated, a simulacrum of a startup. There are a million more talented and capable teams of young people out there.

If someone from a16z reads roy’s post they might finally realize they should ask for their money back.
