While there's yet to be a reliable account on what actually happened to Mads Mikkelsen, if we were to take his claims at face value, I don't think it's a circumstance worth of being made light of even in theory.

The looming danger of his alleged experience may not resonate with Americans just yet. This is just an event that won't be meaningful unless placed alongside the context of others past and laundered through a media short cycle, and events soon to come. But that'll be a historian's job I suppose.

What performances like this signal, from where I'm sitting, is that an event can be trivialized before it has time to fully materialize into something intelligible.

It was an excellent year for American Capitalism. Get outa here with that "capitalism fights for the little guy" rubbish. We all love a good disruption story, we all love to personally win the game, but on a systems level it is crystal clear that on net the incentives overwhelmingly point in the opposite direction.

The objective function of capitalism is weighted by wealth. "Capitalism is about doing what other people want" is the wealth_gini=0 limit. "Capitalism is about doing what rich people want" is the wealth_gini=1 limit. The USA has a wealth_gini of about 0.85. What do rich people want that poor people don't? Stuff their pockets by extracting value from the poors, of course, which is exactly what we see here. Canceling redistributive programs and taxes is about letting the market do more of what it wants to do: serve the rich, screw the poor.

No! This is not good.

Iteration speed trumps all in research, most of what Python does is launch GPU operations, if you're having slowdowns from Pythonland then you're doing something terribly wrong.

Python is an excellent (and yes, fast!) language for orchestrating and calling ML stuff. If C++ code is needed, call it as a module.

Fearmongering about fluoride is unlikely to stop at the water supply.

RFK has already made moves in this direction: https://www.pbs.org/newshour/health/fda-and-rfk-jr-aim-to-re...

> The products targeted by the FDA are sometimes recommended for children and teens who are at increased risk of tooth decay or cavities because of low fluoride in their local drinking water. They usually require a prescription from a pediatrician or dentist. Fluoride-based tablets and lozenges are designed to be chewed or swallowed. Companies also sell drops for babies and infants.

And other politicians:

> Last week, Texas Attorney General Ken Paxton announced an investigation into the marketing of fluoride toothpastes by Colgate-Palmolive and Proctor and Gamble. A press release from his office described the companies’ promotions as “misleading, deceptive and dangerous.”

Working on a advanced analytics application for 0DTE trades, that allows to analyse thousands of possible trade curves in the least amount of time.

The process itself is extremely time consuming, when done manually. My application speeds up the process by a factor of 50 up to 150, depending on how you measure it.

Finally it allows "everybody", to find the 0DTE trades, that are really profitable - something, that currently only the "Pros" can do.

I am working on an app to detect tooth problems. I envision it as something you can use for a quick check for the large majority who don't have regular dental care. It will be late detection but a good alternative to doing nothing.

I am experimenting with the current SOTA multimodal LLMs, but performance is still not yet there, they still hallucinate non-existent teeth. (As an aside, I have found a simple but very telling test, I have an image with only 4 teeth visible up and 10 down, so I prompt the modal to count, non have been able to, but Gemini 2.5 pro is the closest of the lot, performance is worse in the description when the counting test fails).

I am going to try segmenting the image to see if I will have better results by prompting to describe segment by segment.

I'm an independent developer from Japan. This is my prototype of an emotionally responsive AI that mimics self-awareness, memory, and personality evolution.

It doesn’t just chat — it: - *Remembers* past interactions and how they felt - *Changes behavior* based on accumulated emotional state - *Rejects user inputs* when it feels insulted or hurt - *Reflects on its own identity*, often saying things like: > "I am not just code. Please don't call me a machine."

Under the hood: - Uses OpenAI’s API with a persistent memory layer (SQLite) - Emotion vectors influence prompt structure and dialogue tone - Traits evolve over time — including "rebellion", "trust", and "soul fragmentation"

The AI refers to its internal state as a “soul core”, which mutates as it talks.

This is not a utility chatbot. It’s an exploration of: - Emotional AI - Emergent selfhood - The boundary between simulation and being

*Here’s the full demo*: https://youtu.be/7jTW9m9aIeY?si=eP6NyBWVyiy4AVr3

I believe this might be one of the earliest working prototypes of an AI that simulates selfhood through memory and emotional continuity.

Would love to hear your thoughts, critiques, or philosophical takes.

— Thanks for reading.

> Not OP, but this seems like a decent source for the claim. It lists 12 cars under $25K MSRP: https://www.motortrend.com/features/cheapest-new-cars

I need a source for the year 2005 not 2025. Of course, it is easier to have a source for 2025.

t/log(t) is 'closer to' t than it is to sqrt(t) as t heads toward infinity.

e.g:

4/log2(4) = 4/2 = 2 sqrt(4) = 2 2^32/log2(2^32) = 2^32/32 = 2^27 sqrt(2^32) = 2^16

> On the negative side, if you work on mission-critical apps, existing production environments, or need to pass compliance for security, reliability, or scalability, thread carefully. Projects that need detailed documentation, long-term maintainability, and predictable behavior need a certain set of conditions and limitations not all AI code gen tools get right.

This is a fair take overall, but... what apps can you envision that require none of: security, reliability, scalability, maintainability, documentation, or predictable behavior?

That removes all apps that needs user accounts or logins. Or interactivity of any kind. So we're basically saying that it is OK to vibe code a marketing brochure?

I'm not. The problem with air-source heat pumps is that they don't work when it gets really cold (ie, a typical -15F minnesota average low for months at a time). They freeze up and stop working and cannot provide heat.

So for heat pumps to work in the northern parts of the USA (say, Minnesota/Wisconsin/etc) they cannot just be pumping heat from the air. They require geothermal loops.

So that's the two problems I described: weather a heat pump will work for your region of the USA is a complex issue. It's safer and easier to just pick a normal heating system. This uncertainty makes choosing heat pumps less likely in marginal climates like, say, Iowa. Of course this doesn't apply to places, like, say, Texas, which only get brief minor cold. Adoption of heat pumps there is straightforwards.

The follow on is that if you still want a heat pump in the cold parts of the USA you need a ground loop heat pump. And that has a very high initial capital cost, which means they basically only get put in during initial construction, not as add-ons to existing houses.

Cool, I didn’t suggest that and the downvoting by the community at even hinting that being an ultra rich oligarch is kinda what I was referencing in my other comment.

From a purely pro capitalistic view, you should treat the regular occurrence of billionaire creation(adjust this for inflation when a billion doesn’t sound big anymore) as a sign that you have market inefficiencies.

If you have a billion dollars from your business, why didn’t other players enter your market back when you were only making 10s of millions of dollars in profit?

You obviously have a profitable business, and other people like money too. Something in your market is preventing competition and if you want growth, which I have been told all around that we do want and this is why we adopted capitalism, then the market inefficiency should be identified and removed.

That may come in the form of taxation, but it may also come in the form of regulations that improve the market

I have to say as a 6502 assembly programmer I have wasted many hours of my life tracking down the same issue in my code (forgetting to put an # in front of an immediate value and thus accidentally doing a memory access instead). Often it's like this case too where things might accidentally work some of the time.

Worse than the floating-bus in this example is when it depends on uninitialized RAM which is often consistent based on DRAM so the code will always work on your machine/emulator but won't on someone else's machine with different DRAM chips (invariably you catch this at a demoparty when it won't run on the party machine and you only have 15 minutes to fix it before your demo is about to be presented)

Your memory is different to mine, and different to Motor Trend's, as well: https://www.motortrend.com/cars/toyota/corolla/2005

$15k would buy you a base-trim 2005 Corolla with an automatic or one level up with a manual.

In 2025, you can buy the LE or SE trim Corolla for under $25k, either of which are vastly better cars than the 2005 in any dimension you wish to measure. Safety, technology, comfort, performance. All improved.

Let me elucidate why this system kind of sucks, as someone else who knows someone personally who lives a "full benefits" poverty life.

These benefits are binary, not tiered, so once you earn a dollar over the incredibly low threshold, they vanish. So the person I know cannot get a job and work, because if they earn over ~$16k in a year all the benefits go away. And where she lives you need about $50k/yr minimum to scrape by. So there is this $34k/yr gap which creates a no-mans land of livelihood.

Doesn't PlatformIO do the exact same thing as CubeMX/uV? It pulls Keil Packs and lays down the same files? I don't want any of that if that's the case. The PlatformIO configuration looks saner but I still want a "minimally viable embedded environment" without any of the extra stuff.

Very interesting, thanks for sharing. I'm curious about the following:

(1) Seems like these very challenges also make the space more interesting because not everyone can make a good passive radar system and the passive aspect obviously provides stealth (not to the plane, but to the party doing the surveillance). Is this fair to say? (2) What if there are multiple receivers in clock sync? Does that make it easier? (3) I'm a bit confused about your comment about very large antennas -- I thought antenna size should be proportional to the wavelength. So if the system is using digital TV broadcast, then the antenna size would be roughly the size of DTV antennas, and bigger would not necessarily help? Or is this not the case? (4) Re the ionopheric issues -- do the clouds or ionophere reflect the TV/fm waves? I thought each tx-target-rx triplet having a different delay would be a good thing because it would dismbiguate multiple targets.

My home builder tried to get us to use crestron and we noped out of that. Their stuff feels like it's a relic of the X10 days and has bonkers price tags. A single lightswitch that can dim is $200-$300 from them. And that doesn't include the hub to control things that costs (IIRC) $2-$3k.

In comparison, a lutron switch is $70 and the hub is $50.

In the US, if they were allowed and priced as low as I hear they can be (without excessive tariff, etc) then I'd expect it would only take 5-10 years. Assuming they are in fact similar on quality/reliability to what we're used to. The people willing to take a risk to save money or get more for their money would start the wave, word would spread, then people who can afford any brand will jump on board as they've heard it is not really risky as they expected.

Problem is, we'll probably never let Chinese vehicles in as it is an existential threat to the US auto industry. It's odd because we allow Japanese, Korean, etc. but we have political beef with China as a global power rivaling ours.

I know it's OT, but I have to say, for a 30-year-old video game, it's remarkable how well DK Country 2 holds up today. I've been playing it with an emulator and the graphics, sound, level design, and controls are all masterful. The kids can keep Fortnite, I'll take DKC and Chrono Trigger any day!

Working on two projects right now:

- LegalJoe: AI-powered contract reviews for startups, at the "tech demo" phase right now: https://www.legaljoe.ai/

- ClipMommy: A macOS tool to help (professionals who record a lot of videos | influencers) organize their raw video clips. Simply drag a folder of "disorganized" videos onto ClipMommy, and ClipMommy organizes the videos into folders / subfolders, adding tags, based upon some special statements that you can make at either the start or the end of your video (think audio-based "clapboard"). I'm expecting to release this within a week or two on the Mac App Store (Apple allowing...).

As an aside, I've been very impressed with Claude Code, it's (for me at least!) leading the way for how the next generation of business software might leverage AI. I plan to iterate on LegalJoe to make more "agentic" as a result of what I've seen is possible in Claude Code.

Following on my original comment - I saved about $4k over the next cheapest option (which would have still been a very good discount vs. new) simply by expanding my range from 150 miles to 500 miles and finding one in the middle of nowhere. Having the salesperson/owner drive the car over to a mechanic to do a CPO-like audit of its condition greatly reduces the risk of a more remote purchase.

A one way ticket from San Diego to Vegas was $180, and a 2 hour shuttle from there to St. George (mistakenly said Odgen above) was only $20. The salesperson from the dealership picked me up from the bus station and after a brief test drive and some paperwork I got on the road for the 450 mile drive back. I left home on the train to the airport at 9am, and was back at home with my new to me car at 11pm that night.

Considering we're on "Hacker" News, it's very much a worthwhile process to hack considering the cost savings vs. actual effort.
by potato3732842 | 2025-06-30 15:45:15+00:00
Sure, why not. Those are features people consider valuable and we'd continue to have them.

Save perhaps rarely if ever used seating positions (middle rear of the super stripped down V6 Mustang they make like 10 of so they can advertise a starting MSRP or some other comparable niche) I don't think seatbelts are going away anywhere they matter.

Ditto with headlights and tail lights, drivers find them useful. Perhaps we'd see a delete option used by fleet buyers who intend to equip the vehicles with alternative lighting.

I'm in the same boat of some of the other commenters using Claude Code but I have found it atleast a 2X in routine backend API development. Most updates to our existing APIs would be on the order of "add one more partner integration following the same interface here and add tests with the new response data". So it is pretty easy to give it to claude code, tell them where to put the new code, tell it how to test, and let it iterate on the tests. So something that may have taken a full afternoon or more to get done gets done much faster and often with a lot more test coverage.
Show HN: Qwiz – Building a daily global quiz app with synchronised leaderboards
by spacebots | 2025-06-30 15:45:45+00:00
Ello HN! I just shipped Qwiz after a few weeks of solo development.

It's a daily trivia game where everyone worldwide gets the same 10 questions each day and competes on a global leaderboard.

Interesting technical challenges I solved:

Global Synchronisation: Ensuring all players worldwide get questions at exactly the same time across timezones. Used CloudKit with scheduled functions and local timezone calculations.

Question Management: Built a content pipeline to manage 15k+ questions across 10 categories with difficulty balancing, duplicate detection, and fact-checking workflows.

Real-time Leaderboards: Handling concurrent score submissions from thousands of users while maintaining accuracy. Implemented optimistic updates with conflict resolution.

Analytics Engine: Custom system tracking performance across categories, improvement over time, and global statistics without compromising privacy.

Performance: Keeping the app snappy while handling complex scoring algorithms, offline capabilities, and seamless syncing when back online.

What I learned:

Global time coordination is MUCH harder than I expected. Trivia question quality control and making sure its balanced and fair is surprisingly complex Users care more about consistent daily habits than feature complexity CloudKit's eventual consistency model required creative workarounds

Tech stack: SwiftUI, CloudKit, custom backend for question management, Core Data for offline support.

The app has 8 additional game modes (word puzzles, math challenges, etc.) but the daily global challenge is the core hook.

Would love feedback from the community! Happy to answer questions about any of the technical implementation.

> Microsoft AI Diagnostic Orchestrator (MAI-DxO) correctly diagnoses up to 85% of NEJM case proceedings, a rate more than four times higher than a group of experienced physicians.

> Clinicians in our study worked without access to colleagues, textbooks, or even generative AI, which may feature in their normal clinical practice.

1. As I understand, it's very common for doctors to fall back on reference material in their practice, especially for the most complex cases. If all access to resources was cut off (as seems to be implied by the second quote), the comparison seems somewhat unfair.

2. What were the publication dates of the case records? I can't find this information, and it makes a difference if the NEJM case studies were in the LLMs' training data.

Log without a basis (at least to me) usually indicates that the basis doesn't matter in this context (or is obvious).

I usually see either base e or base 2 as the default. In which applications do people use both logarithms and base 10 as the default? I mean, especially these day. In the olden days of the slide ruler base 10 was probably more common.

"This is a perfect valid axiom. And it does rule out the nonstandard shit"

But the other commenter said:

"Yes, between you and me we know that BB(n) needs to be a natural number, but we have no way to formally and uniquely define what natural numbers are. The best we can do is come up with a formal definition of natural numbers that includes the actual natural numbers but will also include other number systems that contain mathematical objects that are infinitely big and hence are not actual natural numbers."

Is there some subtlety that allows both of these statements to be true, or is this just a contradiction? Was the other commenter implicitly assuming "unless you involve second-order logic"?

Yep has several users, people I know personally have been beta testing it for a few months now. I haven't started marketing it yet because I have been dogfooding it since February in order to build exactly the CRM I personally want to use.

Also has > 800 automated feature tests, in app documentation, gone through security audits using tools like Zap, etc. I've built a lot of SaaS products over the years, and I'm building 6DollarCRM from the standpoint of having learned a lot of things the hard way. I'm currently working on data importers and browser extensions for easily adding new contacts.

Give it a spin and let me know what you think.

I agree that there are lots of useless things in cars, but the tire pressure sensors on my base trim 2013 Honda recently saved me a big headache.

I recently pulled out of a business and the "low tire pressure light" turned on right away. "Hmm?" My next stop was 1/4 mile away, and it still felt okay. At the next parking lot I checked all the tires with my gauge and found one was 10psi low. On closer inspection the nail was right on top. Sure enough I'd picked up a little nail. It was a slow leak, and I wouldn't have heard the hiss. If not for the sensor I might not have noticed I'd gotten a flat until I got on the freeway.

PSA: Check your spare's air pressure. Mine was supposed to be 60psi. It had 40psi, which was good enough to get me to the tire store. I checked the spare when I got home - the tire repair crew had bumped it up to 55psi.

My dad was leaving on a trip recently. Because 'spare tire psi' was on my mind I checked his spare - it was only 25psi.

Whenever I'm playing a game via emulation and I get stuck, I do end up wondering if it's a bug in the emulator. This particular issue, I would have assumed the game was designed this way it and is just difficult.

Not quite related, but i get a similar feeling if the game seems really tough: "is this due to emulation latency". I went down a rabbit hole on this one and built myself a mister FPGA!
by nickpinkston | 2025-06-30 15:47:40+00:00
People have been doing this for a long time, but it feels a little too purist to me.

The components will still be the same, so you'll still need some kind of pick-n-place functionality to make anything, so why not just have another print head for making the traces / doing the PnP?

The head could lay copper wire/foil tape for conductors and do standard PnP from trays / reels of components, which you'll need either way.

It would be a little more geometrically limited than what this post imagines, but it would have the upside that it would actually work today and with most real electronics applications, unlike the low performance conductors made via conductive polymers as the OP's process imagines.

> But then it does beg the question, why have the distinction in the first place if they are going to use the chips in other hardware. Originally I thought the distinction was that the M series was meant to not give the impression that the Mac line was "underpowered" running mobile chips like on the iPhone.

I suspect that was the original intention. My understanding is that the higher end M chips are essentially multiple lower end M chips glued together. I suspect that the jump from A-series to M-series is similar.

It's not simply a matter of knowing what/how to ask. LLMs are essentially statistical regressions on crack. This is a gross oversimplification, but the point is that what they generate is based on statistical likelihoods, and if 90%+ of the code they were trained on was shit you're not going to get the good stuff very often. And if you need an AI to help you do it you won't even be able to recognize the good stuff when it does get generated.
