I understand I’m behind in terminology in this space and figured that there at least would’ve been a post to make its way through HN that would explain what the “Atmosphere” is. Apparently this submission was supposed to be that (5 days ago) but it doesn’t define the concept.

> The "Atmosphere" is the term we use to describe the ecosystem around the AT Protocol.

— <https://atproto.com/guides/glossary#atmosphere> (Why on earth is the glossary not alphabetized by the way?)

I think that ATProto is going to win against other decentralized/‘fediverse' protocols in the long run. Bluesky? Maybe not. But I am impressed by the look of other platforms like Leaflet and that one that’s supposed to be an alternative to GitHub or something like that. [1]

I can’t speak on the tech behind the protocol itself but as far as marketing is considered it’s in the lead in my opinion. ActivityPub seems too gangly and Nostr is the worst—as in 'worse is better’—and in a way I’m fond of it because of that.

The planning behind ATProto appears to be far more coordinated than the other two. Despite being the senior of the three, ActivityPub is still going through inter-platform drama (e.g., the Instagram clone that was recently condemned for not handling text-only posts...like an Instagram clone should) and I get the feeling that the mind behind Nostr can care less about coordinating. I look at it more like a toolkit to build a protocol out of than a single one akin to the other two. [2]

[1]: This is my first look at OffPrint. It looks too much like Substack. I hate it. But I figure that the beautiful thing is that in theory I can use Leaflet and you can use OffPrint and I guess our writing is all in the same...atmosphere. Hah.

[2]: Similar to another web project that I’m fond of, Datastar.

The problem is in parts, how confirmatory statistics work, and how journals work. Most journals wouldn’t publish „we really tried very hard to get significance that x causes y but found nothing. Probably, and contrary to our prior beliefs, y is completely independent of x.“

Even if nobody would cheat and massage data, we would still have studies that do not replicate on new data. 95 % confidence means that one in twenty surveys finds an effect that is only noise. The reporting of failed hypothesis testing would really help to find these cases.

So pre-registration helps, and it would also help to establish the standard that everything needed to replicate must be published, if not in the article itself, then in an accompanying repository.

But in the brutal fight for promotion and resources, of course labs won’t share all their tricks and process knowledge. Same problem if there is an interest in using the results commercially. E.g. in EE often the method is described in general but crucial parts of the code or circuit design are held back.

FWIW, people here illegally are already not eligible for Medicaid, [0] so it's hard to see why ICE having access to a roster of Medicaid enrollees would help them with their stated mission of enforcing removal orders.

Then again, we have ICE shooting American citizens in the streets, so I guess the law is whatever they decide it is, not least because our legislative branch is uninterested in laws.

They tried to install it to our home too, but our landlord just didn't do anything to help them to open doors and now we've been soon waiting two years for the connection.

The more I read about DTAG the happier I feel like using our cable connection which, upstream excluded, works quite well.

We're about to buy our apartment in Berlin and that changes things. I hope we have soonpre choice on the fiber operator.

> The insurance part will settle out over time as they get more data I would imagine.

I'm not so sure. The issue is two-fold: First, If you get into an accident and you're at fault, the average damage is a lot more than with an ICE, due to the much heavier weight. Second, compared to an ICE, just about any repair is a lot more expensive. If some of the battery gets damaged, that's crazy expensive. There's also not a good ecosystem for parts - they are more expensive and less modular than with an ICE (or so I'm told).

It apparently is a lot more common for EVs to be declared a total loss compared to an ICE just because of the expense to repair.

> 500$ a year is very little for any car

This is over 3 different cars. And all of them very old (I bought two of them when they were 8 years old, and another when it was 15 years old - still driving that last one).

About $80/year for oil changes. That's it. Then every once in a while there is an expensive repair (brakes, tires, some engine problem, etc). Doesn't happen every year - so the average comes out to $500.

I also don't go to the official dealers. Everything is more expensive with them.

And yeah, the cars are old, so few electronic parts to repair. I imagine if I get another 8 year old ICE, the annual cost to repair will be more just due to the extra safety systems that can go wrong.

> but I opened a Nissan leaf for 8 years and spent less that 2K, of which 1K was for the AC

Leafs are the best case scenario. They're small, not heavy, and thus don't have much tire wear.

This is something I find fascinating about TikTok: on that platform you literally get a few seconds to catch the attention of your audience before they skip to the next video.

You can't just find one hook that works and reuse it forever because people will get bored of it - including if that hook is heavily used by other accounts.

This makes TikTok a fascinating brute-force attack on human psychology, with literally millions of people all trying to find the right hooks to catch attention and constantly evolving and iterating on them as the previous hooks stop being effective.

People don’t really understand what this stuff means and create fucked up processes.

In a blame focused postmortem you say “Johnny fucked up” and close it.

When you are about accountability, the responsible parties are known or discovered if unknown and are responsible for prevention/response/repair/etc. The corrective action can incorporate and number of things, including getting rid of Johnny.
Show HN: Oura (Activity Tracker) MCP Server with Claude
by thedebuglife | 2026-01-25 20:19:24+00:00
I've worn an Oura ring since 2020 and I've been that guy who cross references HRV with everything from supplements, late meals to quitting nicotine. I use the data to tell the difference between 'I feel off' and 'my resting heart rate is 8bpm higher than baseline'. And also for introspection, and to make better decisions in the future as Claude has access to 6 years of journal entries as well. (Yep privacy concern, but I find it worth it for me)

What bugged (lol) me is that I was spending too much time exporting data and manually correlating things. Earlier this year I tried feeding 5 years of data into a custom GPT, and the responses were actually (sort of) useful if it didn't choke.

So I built this as an MCP server, I had no idea how MCPs functioned so this was a good way to learn. It fetches fresh data on-demand rather than choking on a static dump, and the statistical analysis (correlation, outlier detection, trends) happens server-side before the LLM even sees it. When I ask "what predicts my best sleep?" it actually computes the answer instead of pattern-matching on vibes.

Works with Claude Desktop.

You should see it as the triumph of chip manufacturing — advanced, powerful MCUs have became so cheap thanks to manufacturing capabilities and economies of scale means it is now cheaper to use a mass manufactured general purpose device that may take more material to manufacture than a simpler bespoke device that will be produced at low volumes.

You might be wondering "how on earth a more advanced chip can end up being cheaper." Well, it may surprise you but not all cost in manufacturing is material cost. If you have to design a bespoke chip for your earbuds, you need to now hire chip designers, you need to go through the whole design and testing process, you need to get someone to make your bespoke chip in smaller quantities which may easily end up more expensive than the more powerful mass manufactured chips, you will need to teach your programmers how to program on your new chip, and so on. The material savings (which are questionable — are you sure you can make your bespoke chip more efficiently than the mass manufactured ones?) are easily outweighed by business costs in other parts of the manufacturing process.

I don't think Linux has an equivalent of Apple's vision API, and if it does I guarantee it's not as robust and isn't baked-in to every Linux distro (the way Vision is baked-in to every Mac released after X date).

That alone will likely prevent this from just being a "convert to Linux" vibe session ... which is unfortunate, as I would LOVE to have this on Linux.

Huh, no. Pollution close to humans is bad for both city and rural people.

> The pollution always goes somewhere,

"The solution to pollution is dilution". We want the concentration of pollution low, so the health effects are low too, and we can give natural processes the time to decay/oxidize/etc the pollutants.

> not like we have large swaths of useless places

We do... we mostly care about the lower ~100 meters of atmosphere because that's where people live. That's less than 1% of the total atmosphere. This means we can distribute pollution over a volume a 100x larger than that that is important for us. And then I'm not even counting the vast amount of the planet that's uninhabited / non-land.

Also, smokestacks are designed to not directly pollute the air close to people, see:

I’m curious about this. Could you please point to some things the CEO has said, or reports of shard failures?

The bit about paying for publicity doesn’t bother me.

Edit: I haven’t found anything egregious that the CEO has said, or anything really sketchy. The shard failure warnings look serious, but the issues look closed

If you think the SCOTUS has been arbitrarily rubber stamping the administration's goals, you haven't been paying attention. I'll fully agree with you it appears to have been fairly partisan, but less than a month again they blocked the administration from deploying the national guard to states:

>In one of its most consequential rulings of the year, just before breaking for the holidays last week the Supreme Court held that President Trump acted improperly in federalizing the National Guard in Illinois and in activating troops across the state. Although the case centered on the administration’s deployments in Chicago, the court’s ruling suggests that Trump’s actions in Los Angeles and Portland were likewise illegal.

You can do this on many Android phones. You can have up to 5 WhatsApp numbers on a Samsung phone.

Samsung has dual messenger, so you can have 2 instances by default. Then you can open up a work profile and have another two. Then install WhatsApp in a secure folder and have another one (dual messenger seems blocked in secure folder so just one)

not totally random, that black and white velcro American flag-like patch seems to be a common sight, like all the temu/amazon/walmart mallninja stuff.

its easy to obtain, and coupled with masking, makes it easy pickings for imposters.

Thank you!

We actually made the course ourselves, following James Stewart's Calculus and our own approach to teaching these topics (we're two PhD students). We wrote everything in English first, then translated it into other languages.

AI accelerated our workflow, we prompted the visuals and explanations we wanted, then polished the results ourselves. So we're confident in the teaching quality and correctness of these videos, they're not pure AI artifacts :)

That logic doesn't hold up.

Legal immigration - as is today - is about 1% of the US population. That's pretty standard, and would result in an slowly increasing population.

But regardless, saying "we need immigrants" then jumping to "illegal or not" is not a logical argument. We absolutely can have a system that prevent illegal immigration, while carefully screening legal immigrants. Heck, every country in the world does this except the US.

I’ve recently really gotten into playing Starfield by Bethesda and you can turn the difficulty up and down, they obviously put a lot of systems in that they decided most people would find annoying and not fun, so they kept it in but gated it in granular options menus that give you an exp bonus.

Like becoming dehydrated and malnourished if you don’t eat every half hour, which is pretty easy to manage, not being able to carry as much, turning damage up, and increasing afflictions so when you get hurt you have to go see a medic and can’t just cure them, although you can stabilize them.

While those ones are okay, and I’ve turned them on (like the weight being lower has a skill that you can add to mitigate, and items that make you stronger), there’s environmental afflictions on certain planets, but they didn’t put sufficient mitigations in the game to combat them. So a high air pressure planet or high solar radiation planet, even if you get a protective suit it gives you maybe two minutes of mitigation, not nearly enough time to do anything productive while walking on the planet, so if you crank the difficulty up those planets just become totally off limits, since there’s no way to “plan effectively and feel clever”, instead you just get burns and then come down with pneumonia and it’s not fun.

I think you could make it engaging, maybe by leaning harder into the robots automation and allowing them to do more tasks, or having diving style space suits for higher pressure environments.

To your larger point I don't think engineering logic is necessarily superior to financial logic, or manager logic. The problem is that because of the way we have built our society, engineering (and all other fields) must comply with and be subservient to bureaucrat and lawyer logic. The legal defense against an engineering failure is not to prove that your overall failure rate is low and within acceptable limits, but rather to come up with as long a list as possible of safety measures and policies that you followed without any regard to whether they actually have any effect at all.

I think the physics of the situation don't make a barrier feasible: a derailed train going >100 mph is going to transfer a lot of energy to any kind of barrier it impacts, which in turn might exacerbate the situation (by spreading debris).

I think these kinds of accidents are largely mitigated by rail defect monitoring. I know rails in the US are equipped with defect detectors for passing trains; I'm surprised that a similar system doesn't exist for the rails themselves. Or more likely, one does exist and the outcome of this tragedy will be a lesson about operational failures.

I agree.

The issue is a significant minority of techies used ethnic nativism instead of a more pluralistic/American nationalism in their pushback instead of arguing to reform the H1B program to disincentivize bad actors (and tbh, we had an opportunity to reform it when I was on the Hill, but it got stuck because of DACA).

This made the whole concept become a zero-sum game instead of a stag-hunt, and led to significant animus and resentment amongst members of the diaspora.

This played a role in Nir Zuk and Gili Raanan building the Israeli ecosystem in the 1990s following what was viewed by Israelis as unjust American pressure during the First Intifada and what Fei-Fei Li and Andrew Ng did to help build the Chinese ecosystem in the 2010s during what was felt by Chinese as unjust pressure during the SCS Crisis in 2016-17. This is also what a large number of Indian Americans are now doing and feeling as well after 50% tariffs, GOP politicans calling our gods demons, and supporting Pakistan.

This only leads to American industries increasingly getting isolated and falling behind - as can be seen in Cybersecurity's hard shift to Israel and India as well as Material Chemistry's shift to China.

This is why good writing on the web is broken up into multiple posts split by concern, and with links to the others at the top of the article.

The real problem is when they SEO the shit out of it and replace those links with irrelevant trash meant to steal your attention and people only want to share the "make me care" posts.

The writers stop bothering even posting details when they have them. They bury the lede because it's what the "make me care" crowd forces them to do.

This is neat, some years ago i also thought of making a simple DPaint clone (though much simpler than what this project seems to do) and started by... painting the tool icons, then losing interest :-P. I did end up reusing them for a pixelart editing component for Lazarus though[0] (and put the icons in my "Bad-Common-Icons" icon set[1] that i use for my GUI programs). But i do want to, at some point, tackle making something like Paint Shop Pro 7 (for desktop, not web) because i think it has the best UX of all image editing programs (including later versions of PSP which i never liked).

That said, i played with this a bit and found some bug with the smudge tool blending[2]. It also seems browser-related as it has different behavior in Firefox and Falkon (which uses QtWebEngine / Chromium). Also the way opacity works with the smudge tool feels weird/wrong as even at 1% it seems to affect the image a lot even though it should barely make a difference.

Someone may have already been curious about the topic beforehand. I’m guessing they already have some kind of itch or curiosity. For example, someone who is interested in reading a dense technical textbook that gets straight into the details likely has a preexisting question waiting to be answered, which is why they care. That’s what motivates them to keep reading, even when the material jumps directly into the details

ICE and DHS already were bloated and somehow grew from not existing 25 years ago to a $100 billion budget. Then the big Trump spending bill added another $200 billion to their budget. And there’s no accountability for who gets that money - it’s all friends and donors and members of the Trump family.

They have money for this grift of epic scale but complain about some tiny alleged Somalian fraud to distract the gullible MAGA base. And of course there is somehow not enough money for things people actually need like healthcare.

> Like blameless postmortems taken to a comical extreme where one person is always doing some careless that causes problem

Post-mortems are a terrible place for handling HR issues. I'd much rather they be kept focused on processes and technical details, and human problem be kept private.

Dogpiling in public is an absolutely awful thing to encourage, especially as it turns from removing a problematic individual to looking for whoever the scapegoat is this time.
Show HN: QR Code Editor with static and dynamic QR codes (client-side first)
by assetofbaskets | 2026-01-25 20:28:07+00:00
Hi HN,

I built a small QR code editor after repeatedly running into the same problem: once a QR code is printed, the destination is frozen.

This tool supports both:

Static QR codes (generated entirely client-side)

Dynamic QR codes (editable destination after creation)

Dynamic QR codes come with a minimal dashboard where you can:

Update the QR destination without reprinting

See basic scan stats (count, device, time, approximate origin)

I intentionally kept the feature set small and avoided heavy analytics or tracking. The goal is something simple that works well for menus, flyers, events, and small businesses.

The app is live here:
https://qrcodeeditor.com/

I’d appreciate feedback on:

What’s missing for this to be useful day-to-day

Whether dynamic QR codes are something you actually need

What you’d expect before paying for a tool like this

Thanks for reading.

I don't know why I'm being downvoted, but I live in a developing country where the tailpipe emissions from a modern well maintained car are literally cleaner than that of commercial (power) plants - potentially making EVs worse. Ofc I'm sure it's much nicer if you're in a 1st world country, but unfortunately that's not where I am.

> I mean, this isn't even a very hard thing to model.

Could you please explain in more detail what exactly do you want to model here? Above, you mentioned "advancing electric car technology so they're cheaper than ICE cars". Now as we both know the issue is with the battery, do you just want cars with battery so small that the car is cheaper than an ICE but nobody wants it? Because there is no need to model that, it has been tried and failed.

If you mean modeling battery technology that's not yet available in EVs, good luck with that. There are better batteries available than in mass-market vehicles, but they are not cheaper; cheaper technologies are not as good. Sure, in 10 years the batteries will be much better overall, but we don't really have the luxury of waiting until the technology gets perfect and then scaling that, do we.
