Dear lord in heaven I hope this is true. My work laptop is an M2 Air and I recently got them to spring for an M5 iPad Pro as a companion device. Whenever I'm using it as a wireless second screen I am acutely aware that it both has a larger display and significantly more powerful processor than the laptop it's serving as an extension of.

Because part of the price of a work of art is its perceived historic / cultural importance. Autographs are taking this to the extreme, where only the mark of the author exists, on its own, and still gets a high price. On the other end, fakes and very accurate reproductions, would never be as valued even if the effect as a visual piece is practically the same.

The colors are all roughly the same lightness? If so, for people with color deficiency, you want the lightnesses to vary because people that can't easily tell certain hues apart should still be able to tell different lightnesses apart (although, if you need a color for lots of different pie slices, the lightnesses you can pick will start getting too close together and you might have to resort to patterns).

Glad to see yet another RSS/Atom feed reader project on HN. This is a favourite topic of mine. The more such projects we have, the merrier. I often mention, here and elsewhere, that adding an RSS/Atom feed is one of the best things one can do for a personal website, provided one wants to be part of the loose social network and ecosystem that exists around RSS/Atom feeds.

Some detractors might say that RSS is dead today, but the reality is far from it. In fact, most of the traffic to my personal website comes from RSS feeds. A little game on my website even became moderately popular after someone discovered it via my RSS feed and shared it here on HN [1].

In fact the three largest sources of traffic to my website are, in decreasing order, RSS feeds, newsletters and search engines. Reviewing the referer (sic) data in my web server logs from time to time, I was surprised to discover just how many community maintained tech newsletters exist on the Web and how active their user bases are. Once in a while, a newsletter picks up one of my silly or quirky posts, which then brings a large number of visits from its followers. But I digress. Let me get back to talking about RSS/Atom feeds.

So I was saying that there is indeed a decent user base around RSS feeds. I can see from the 'referer' logs that every time I publish a new note or article on my website, a good number of visitors arrive by clicking a feed entry that shows up in their feed reader. I know this with some confidence by looking at the 'referer' headers of visits to my HTML pages and the subsequent browsing of the website, as opposed to the isolated and automated fetches of the XML feeds. So there must be a reasonably active base of users around RSS feeds. It is a bit like being part of an invisible social network that we know exists and that we can measure through indirect evidence.

Many personal websites publish a blogroll with a list of their favourite bloggers. One thing I wish more blogrolls had is links to the bloggers' feeds or, even better, an OPML file that I could import into my feed reader. Then I could keep multiple collections of blogs in my feed reader, for example Alice's Blogroll, Bob's Blogroll and so on. I do publish an OPML file for my blogroll [2], and I urge other personal websites with blogrolls to do the same.

If you train yourself to expect the highs of unhealthy food with excess carbs, sat fats, and salt, which is what restaurants, junk food, and high carb liquids have, then no healthy food is going to be tasty enough.

If you eschew those highs and settle for some sprouted moong bean salad with a little bit of salt/lime/black pepper, or hummus and veggies, or eggs with some smashed avocado on toast, tofu and some broccoli, etc, then it does not cost much time.

There is no baking involved, just cutting, mixing, blending, and maybe soaking. Sautéing or pan frying in a little bit of olive oil or canola oil is also quick.

Hi HN,

I’ve been building autonomous agents and hit a persistent architectural flaw: system prompts that dictate persona are brittle. Over long context windows or multi-turn orchestrations, LLMs inevitably drift from their assigned character into a generic, sycophantic tone.

Hardcoding adjectives ("be helpful but sarcastic") scales poorly and yields non-deterministic variance across different base models.

I built PersonaNexus to address this. It treats agent identity as configuration rather than prose.

How it works:

1. You define the agent in a strict YAML schema.
2. Instead of guessing prompt adjectives, you use established quantitative psychology frameworks (OCEAN/Big Five, DISC, Jungian).
3. The compiler validates the schema via Pydantic, maps the psychological vectors to semantic constraints, and generates a deterministic, model-agnostic system prompt (or JSON payload).

It supports inheritance (archetypes/mixins) and isolates hard/soft guardrails from the core personality matrix to prevent safety instructions from bleeding into tone.

I open-sourced it to test if this structured approach is viable for production, or if I am over-engineering a problem solved by better prompting.

PyPI: pip install personanexus

I would appreciate technical feedback on the Pydantic schema design, specifically the conflict resolution logic when inheriting multiple conflicting mixins.

You can try it. Parents should try what they want and there is a huge amount of "you must do it this way or else" material that just produces unnecessary stress.

My observation is that there is limited research showing that this actually works and that the amount of extra effort required to constantly be observing the baby for these cues makes the already extremely difficult task of caring for a baby just more difficult, even if it did work.
Show HN: BXP – An open standard for atmospheric exposure data
by BXP | 2026-03-08 14:53:36+00:00
Air pollution kills 7 million people a year. The sensors exist. The data infrastructure does not.
Every device, app, and agency stores air quality data in incompatible formats. A sensor in Accra cannot speak to a hospital in Nairobi. A researcher in London cannot access ground-truth data from Lagos. There is no open standard for atmospheric exposure data — the same way there was no open standard for the web before HTTP.

BXP (Breathe Exposure Protocol) is my attempt to fix that.

It defines: — A universal .bxp file format any device or software can read and write — BXP_HRI: a composite Health Risk Index incorporating all agents with WHO-derived weighting — A complete REST API specification for federated node networks — A privacy framework protecting individual exposure records by design

Like HTTP, PDF, or MP3 — BXP is a format layer. No hardware required. No licensing fees. No central owner. Apache 2.0. Forever free.

The reference implementation is live right now:

Live public node: https://bxp-node.onrender.com
GitHub + full source: https://github.com/bxpprotocol/bxp-spec
Spec DOI (Zenodo): https://doi.org/10.5281/zenodo.18906812
Implementation DOI: https://doi.org/10.5281/zenodo.18907003

You can clone it and run your own BXP node in under 3 minutes:
git clone https://github.com/bxpprotocol/bxp-spec
cd bxp-spec/reference-server
pip install fastapi uvicorn pydantic
python server.py
The spec covers 31 atmospheric agents — PM2.5, NO2, ozone, benzene, mold, heavy metals — with WHO thresholds, quality flags, geohash-based spatial indexing, and a federated network architecture where each node operator owns their own data completely.
I am looking for developers, researchers, and institutions who want to implement BXP, contribute to the spec, or run a community node. Particularly interested in connecting with anyone working on air quality infrastructure in developing countries where the data gap is most severe.

Happy to answer any questions.

I tested something similar and continous re-transcription was the only way I could get close to batch-level accuracy.

In my current implementation I’m fairly aggressive with it. I don’t rely much on streaming word confidence. Instead I continuously reprocess audio using a sliding window. As new audio comes in, it’s retranscribed together with the previous segment so the model always sees a longer context.

That recovers a lot of the accuracy lost with streaming, but the amount of retranscription makes it hard to justify economically with cloud APIs. That’s why I’m focusing on a local-first approach for now.

> Incredible digging

Thanks. I appreciate your kind words, I was thinking of writing some piece/blog about it but procastination is definitely something :) But I am just happy that I finally wrote a comment atleast explaining all/most of my understanding. That's more than fine for me.

> Incredible digging. I remember reading comments about the reason the price hike was the Sam Altman secured a deal with the few ram producer in secrecy were they promised to reserve a large portion of their production to OpenAI for the next years (I don't remember how long). Supposedly Sam will just to put them in a warehouse to collect dust.

I do believe that's gonna be the case as well. Most of the ram is probably not needed currently (thats what I feel like) so its gonna sit on dust, That, or oracle/microsoft will use it within their datacenters as old ram breaks apart to have some more monopoly given their close ties to OpenAI.

Even if OpenAI internally sells them at half the market price to microsoft/oracle, they still technically turn a profit.

I actually felt too conspiratorial thinking about it when I had first discovered it because I was under the previous assumption that OpenAI actually needed the ram myself too. But seeing recent events of OpenAI with Department of Defense, I definitely think that they did this on purpose.

Cloth diapers are good. We used them for our last kid with a diaper service and are going to do it again washing them ourselves with our next who is due at the end of the month. Regular diapers are useful to have either way. But cloth diapers are obviously much better for the environment and if they're an option for you, you should consider them. Not a hard concept, not worth a big discussion.

I've been doing SEO for a while and always had the same frustration: backlink lists with no way to know what's actually there on the live page. Every tool pulls from databases nobody checks the actual URL the way search engines do. So nobody really knows what they're working with.
Verify Backlinks takes any backlink Excel file and checks every link live on the URL — placement context, manipulation patterns, indexability signals, language alignment. Not from a database. The actual live page.
Output per link: Keep / Review / Consider Disavow with Excel workbook, PDF summary, and disavow.txt.
First time I actually knew what to do with my backlink list.
Sample report: https://verifybacklinks.com/sample-report/
BetaList: https://betalist.com/startups/verifybacklinks
Curious if anyone else thinks about live-URL verification in their SEO workflow.

Tangential: I decided to write a Wasm parser (more precisely, a decoder the the Wasm binary format) from scratch, as a means to learn both Wasm and Rust[0].

It was the first time I was writing this sort of thing, but I found the spec very clear and well-written.

Fun fact: I was surprised when the test from a toy parser surfaced a real regression in version 3 of the spec[1], released roughly 4 months before.

I get what you’re saying, but it’s not as though there are trillions of books and blog posts and stackexchange questions about excel and the handful of other things that most office workers do, too.

I honestly figured that’s why everyone is coming out with MS Office plugins for all the models, and MS itself is putting it in the tools.

So if most any company only needs one person to solve limited IT issues, prompt code production and deployment, generate the usual truckloads of excel spreadsheets, and do most of the finance and accounting… it starts to look pretty scary.

Then, what about the people making and maintaining all the facilities for these people we don’t need anymore? The world flipped its lid about commercial real estate when wfh became a thing. That was relatively small and temporary.

It costs the same, we just mark it as an opportunity cost of unloading the memory on the spot market.

If I buy contracts for 1 gold bar at $500, and the gold price runs to $1200, I can either continue to market my gold-containing product for the same profit margin, or I can unload all that gold for $1200/bar and make a profit of $700/bar. If my profit margin is high and it doesn't take many gold bars to make a thousand units, maybe discontinuation doesn't make any sense. But if my product is "solid gold statuary of Dear Leader", and the bars are most of my cost basis, I know what I'd do.

And if you lived in a state that published open data you could see this happen — hospitalization rate goes up and bed count goes down, and we’d go to tighter restrictions until the trend reversed and the bed count went back up. A lot of the public health response wasn’t about stopping COVID transmission, it was about limiting the effect on a hospital’s ability to provide care for things like life-threatening injuries.

I don't care if anyone uses cloth diapers but the cloth diaper evangelists always seem to take a page out of the people who say "renting is always bad" or "leasing a car is always bad." Focusing on the (completely legitimate) negatives associated with the thing they don't like, and completely ignoring the (no less legitimate) negatives about the thing they like.

I don't see it anywhere here, which is refreshing, but there's also something about cloth diaper use that lends itself to people making it their entire personality.

I’d be okay with it generating the posts and the reports of the financials and such but you need some human interaction in there.

Generate the posts with AI so it can free up your time to interact with people replying to the post.

Or write the bigger, longer, more content posts yourself with maybe some AI assistance in places here and there then use AI to create smaller posts from your larger posts. Still keeping with the human interaction with those that reply to the posts.

I spent the last couple of weeks away from a laptop, which meant actually finishing The Brothers Karamazov.
The thing that surprised me most was how contemporary it feels — not in a shallow "timeless wisdom" way, but structurally. The narrator is semi-omniscient but explicitly unreliable and self-conscious about it. The characters have inner lives that contradict their stated beliefs. Ivan's devil predicts satellites. The diagnosis of over-specialization in medicine (one doctor for the right nostril, another for the left) landed differently than expected.
Most of all: the psychological model of humans in that book is still more sophisticated than what we use in most social science today. That felt like an uncomfortable observation worth sitting with.
The post also has some notes on Grapes of Wrath, a couple of essays worth rereading, and the new Hallmarks of Cancer paper if you're into that sort of thing.

I have it running locally, but speed is a problem. I have the 35GB model running on a PC with 64GB, a fairly new processor and a mid-level GPU. Ask a question, go drink a coffee.

I mean, it's great that so many models are open-source and readily available. That is hugely important. Running models locally protects your data. But speed is a problem, and likely to remain a problem for the foreseeable future.

That’s a massive oversimplification of the field's trajectory.

Google introduced the Transformer model in 2018. They built interactive voice response (Google Assistant) and applied it to web search but didn't do much more because they considered reliability to be an issue.

ChatGPT was introduced in 2022. It was based on the Transformer model as are all the current AI chatbots.

ChatGPT's big innovation was scale. They spend billions to digitize everything they could find on the web and beyond and market it as a general purpose AI.

Even with a world of data, reliability remains an unsolved issue.

It's not irrelevant, because if SPEC 0 says that a particular Python version is no longer supported, then libraries that follow it won't avoid language or standard library features that that version doesn't have. And then those libraries won't work in the corresponding PyPy version. If there isn't a newer PyPy version to upgrade to, then they won't work in PyPy at all.

If you consider just Wasm 1.0 and 2.0, the amount of “runtime” is relatively sparse.

A tool like wasm2c (or my wasm2go) shows this: there is no huge runtime to carry, just a fairly direct translation of Wasm byte code to C (or Go).

What’s the point of having 27 threads accounts, rather than 1 high quality one?

Do none of these places care if they’re botted?

Thanks, I have updated the comment. I had thought that it was 200 but its actually 1700 and also for the official link.

From the link that you shared:

It's currently the seventh-greenest computer in the world, he said.

"This particular system is about half a petaflop, or capable of about 500 trillion calculations per second," he said. "In the current time that we can measure it, it's about the 35th- or 36th-fastest computer in the world, and with some things that are going to be changing in the next eight or nine months with some upgrades, we could boost it to maybe the 20th-fastest computer in the world, and at the same time make it, at that moment in time, the greenest computer."

Do you feel like something like this can again be possible with Linux being ported to PS5 now? I don't quite understand why sony would remove the linux feature from ps4 if this was something that the govt. was benefitting from. I assume that the govt. must have put some pressure to still allow linux on ps4/ps5 given that it was benefitting from it in the past?

Agreed on the strollers. There are medical reasons sometimes or whatever I’m sure, but that doesn’t explain most of them. We pushed ours to walk outdoors as much as possible as soon as they could walk at all, otherwise you end up with the 6yo with an iPad in a stroller at the zoo, wtf. Can’t let them get used to anything you don’t want to keep doing for a looooong time.

> It's ok to send your kid to school/daycare with holes in their socks.

My kids wreck clothes. Others (like the people we buy them from, used) seem to fare better but each of my kids probably puts four holes in clothes per week, not even considering stains. Sure you can mend them but not when you discover the hole two minutes before you have to be out the door.

> Kids' clothes are forever dirty

Mine never, ever were as a kid—but I had one homemaker parent. You can do a way better job at this stuff while also feeling less-stressed and overall doing less total work under those circumstances. Between paid work and non-fun kid stuff / housekeeping my wife and I put in probably 70 hours a week, each, and don’t keep up as well as my mom did (granted, we have more kids too, but still). Coordination costs and having to chop the work into little bits between other things makes it way less efficient, and it can be hard to get to everything quickly. Things that go wrong Monday may not get addressed until the weekend, where my mom would have had it taken care of within an hour.

> Modern American middle class norms are that babies cost a fortune.

> The best nutrition, daycare, early childhood learning, classes, tuition, etc. Extreme expenses.

Daytime childcare isn’t really optional in the first few years. Our system assumes both parents will work. In many metro areas childcare alone can take close to half of a median household income, and daycares are even pretty notoriously low-margin businesses. Moving somewhere cheaper is possible, but that often means fewer job opportunities and lower earning potential.

The result is a tough set of choices for Americans looking to have children:

1) Earn well above the median so childcare costs are manageable (obviously not an option for everyone)
2) Accept a massive drop in your standard of living after having kids, possibly to the point of impoverishment
3) Decide not to have children

Maybe that’s the part of the system worth questioning first.
