Hi everyone
I recently launched HeartRateTap — a completely free, zero-download web site that lets you check your heart rate by simply tapping (or pressing the spacebar) in rhythm with your pulse. No phone camera, no wearable, no sign-up — just your browser and your fingertip.
It’s designed for quick wellness checks: whether you’re curious about your resting heart rate after waking up, or want to estimate your exercise intensity during a home workout.
Features so far:
Real-time BPM calculation
Resting & exercise heart rate reference charts by age/gender
Visual pulse map and heart rate zone indicator
Local-only storage (your data never leaves your browser)
Fully responsive + keyboard support (spacebar = tap!)

But as the solo developer behind this, I know I’m missing blind spots. That’s why I’m reaching out to you!
Could you take 1–2 minutes to try it out and share your honest feedback?

Is the UI intuitive?
Did anything feel confusing or slow?
What features would make this actually useful in your daily routine?
Any bugs or UX quirks on your device/browser?
Your input will directly shape the public roadmap — and I will read every suggestion!

Try it here: https://www.heartratetap.com
Or reply here / email me at mailto:cloudhu2000@gmail.com
Thanks so much for your time and kindness. Let’s make heart health a little more accessible — together

Yeah understandable. If you've got the hardware for it, consider looking into Flux.2 Dev with the Turbo LoRA. It's probably the best-in-class for sheer prompt adherence right now, though Qwen-Image is still very respectable.

And of course, we should see Qwen-Image 2.0 become open-weight in 4-6 weeks as well - so good things on the horizon!

I'd look to Google's ADK for what enterprise open source / production features look like. Available in { python, java, golang, typescript } at varying levels of maturity. Work appears rapid (I maintain a fork for adk-go, which includes sandboxing, time travel, and a few bug fixes / enhancements). Great interfaces that are easy to extend with code.

> needing to know obscure things like Win+E

I'm sorry but this is a skill issue. This is the second hotkey you learn in Windows, after Win for start menu, and before win+left/right to snap windows to sides of the screen.

Regardless, the whole flow both of you are talking about can be done on Windows without ever touching the mouse. Win+E Win+E Win+Left Enter Alt+D "destdir" Enter Alt+Tab Alt+D "sourcedir" Enter (arrow to whatever you want) ctrl-X Alt+Tab ctrl-V.

I use Linux with i3wm at home, I haven't used Windows as my main OS in nearly a decade and I can still play out those keystrokes in my mind without thinking about it.

Now, win+E -> click folder -> alt+D -> "powershell" -> enter? That's power user shenanigans.

What do you mean by "per hour"?

Watt is a measure of power, that is a rate: Joule/second, [energy/time]

> The watt (symbol: W) is the unit of power or radiant flux in the International System of Units (SI), equal to 1 joule per second or 1 kg⋅m2⋅s−3.[1][2][3] It is used to quantify the rate of energy transfer.

We can write new laws when new things happen, not everything has to circle back to copyright, a concept invented in the 1700s to protect printers' guilds.

Copyright is about granting exclusive rights - maybe there's an argument to be had about granting a person rights of an AI tool's output when "used with supervision and intent", but I see very little sense in granting them any exclusive rights over a possibly incredibly vast amount of AI-generated output that they had no hand whatsoever in producing.

> Maybe the motherboard? Could that have a speaker built into it? That must be terrible for acoustics, but maybe useful for a little beep when something is wrong?

Yes, it was called the PC Speaker, and that's pretty much exactly what it was used for. https://en.wikipedia.org/wiki/PC_speaker

It was standard equipment through the (mid?) 90s, and completely independent of the (optional) PCM sound card.

Now PCM sound is built in to motherboards and the PC Speaker long ago faded into irrelevance. Modern motherboards don't even have headers to connect a PC Speaker. Some motherboards will emulate the PC Speaker over the built in sound output, but of course you need speakers plugged in and on to hear those beeps.

Hmm, I am not sure the missing front fork is worse than the unsteerable front wheel mountings (which look like rear wheel mountings) most models so far have produced. It might be better... sort of an admission of an unsolved problem in design of the bike rather than producing something that looks approximately correct but can't possibly work. Like a "TODO" comment in code.

Also the position of the pelican on the bike would be somewhat awkward, but fits anatomically with a pelican's relatively short legs. In fact I can remember riding (or trying to ride) an adult bike as a young child using a similar position.

Reminds me a bit of the Park of Aging in Miraikan The National Museum of Emerging Science.

I remember when staff casually handed me a paper brochure near the area dedicated to aging that when opened was blurry and difficult to read. I was confused. When it finally dawned on me this was one of their simulations of old age I never laughed (at myself) harder. Such a fun and educational experience highly recommend for all ages.

So uh, funny story: I didn’t know this a few years back. GDC was missing the sqlite interface in GDC’s phobos. This made it so the dlang onedrive client and some other packages wouldn’t compile with it. Situation was like this for years: https://forum.dlang.org/thread/doevjetmiwxovecplksr@forum.dl...

You were right the first time, the holier-than-thou sanctimony is a bit much, especially as it relates to these developments.

Nearly half the potentially responsive files still withheld (per reports of ~6M pages collected but only ~3.5M released, plus heavy redactions and privilege claims), and HN top commentary is about not rushing to judgement and conspiracy theories... maybe it's because the government is literally running an active cover up on a child abuse scandal that involves the billionaires, the elites, and threatens to take down entire governments.

>It's hard not to feel like a lot of people want to paint a picture that Jews are especially depraved and amoral.

That is because it is true, a lot of people do want to paint all Jews like that. People would probably find the catholic church stuff even juicier if the vatican was running an intelligence agency that brokers with most other western intelligence agencies with these same rapists.

The thing with Epstein is that he really seems heavily connected to intelligence. Maxwells dad is alleged to be a Mossad agent. There are pictures of him in meetings in his office with a map of Israel, gaza, and the west bank on the wall. There are FBI documents that allege epstein himself was at least at one point a Mossad agent.

So you have this compelling israeli intelligence angle. The fact that global elites genuinely partied with this man. All the history of the case from the sweetheart plea deal in 2007 that stopped the federal investigation at the time in its tracks and granted immunity for potentially involved parties, the fact he was never actually convicted before he died (even that is suspect), the fact that outside Maxwell no one has been arrested.

I mean it really quacks like a tin foil hat global elite conspiracy. That is what makes this story so damn juicy and compelling. It isn't just a couple priests getting their rocks off with some alter boys, but an entire systematic thing where its looking like this guy was not only trafficking girls but running some sort of Bene Gesserit esque breeding program impregnating teenagers he thought had good genetic traits.

You couldn't even write this stuff into a movie it is so wild and hardly believable if it wasn't coming from DOJ evidence respositories.

That is the thing about these conversations, is that the issue is potentiality. It comes back to Amara's Law; “We tend to overestimate the effect of a technology in the short run and underestimate the effect in the long run.” Its the same thing with nuclear energy in the 1950s about what could be without realizing that those potentials are not possible due to the limitations of the technology, and not stepping into the limitations realistically, that hampers the growth, and thus development, in the long term.

Sadly, there is way, way, way too much money in AGI, and the promise of AGI, for people to actually take a step back and understand the implications of what they are doing in the short, medium, or long term.

> While you are at it, cancel all those streaming subscriptions, and stream for free in the high seas

Setting up jellyfin+plex (some devices support one but not the other) and most of the arr suite (radarr, sonarr, prowlarr, tunarr) has really been the best choice I've made this year. I have every TV show or movie I ever want to watch, all my favorites, all the classics. And all in one place. And I made sure to keep it local-first so I still have access at home if we lose internet. Started sharing with family and friends and I get a few requests a week to add content, so its being used.

Just removing the "what streaming service is this show on that im watching?" has been a nice improvement.

A Dododo Land on that premise would be more interesting than what is described, which is weak tea social commentary. A Dododo Land where the doors are confusing and you have to pull rather than push - where there's typos everywhere and the kerning is always inconsistent or sometimes the font randomly changes and everything is hung 1 degree off level - where you pay for a ticket but then it errors out at the entrance and the clerk tells you that your payment must not have gone through - where a few lights just flicker once in a while and there's an odd high-pitched sound that half your group can't hear but sounds like tinnitus - where the employees are reading manga and you have to get their attention by coughing loudly - ...

Hi HN — creator of Phonchain here.

Phonchain is an experimental mobile-native L1 secured by real smartphones instead of hashpower or stake.

Each participant contributes periodic device-signed heartbeats (PoP-Secure S4), aggregated into blocks with a fixed target time (5 min) and Bitcoin-like supply schedule (21M cap).

The goal is to explore whether large-scale phone participation (potentially tens of thousands per block) can provide Sybil-resistant security without specialized hardware.

Reference implementation and bootstrap endpoints are public if anyone wants to run a gateway or core node.

Happy to answer technical questions.

I guess argument seems to be that any AI capable of eliminating all of humanity would necessarily be intelligent enough to cure all diseases. This appears plausible to me because achieving total human extinction is extraordinarily difficult. Even engineered bioweapons would likely leave some people immune by chance, and even a full-scale nuclear exchange would leave survivors in bunkers or remote areas
by overgard | 2026-02-13 06:41:22+00:00
They aren't truly intelligent so we shouldn't consider them to be. They're a system that, for a given stream of input tokens predicts the most likely next output token. The fact that their training dataset is so big makes them very good at predicting the next token in all sorts of contexts (that it has training data for anyway), but that's not the same as "thinking". And that's why they get so bizarelly of the rails if your input context is some wild prompt that has them play acting

There are reasons not to like gypsum drywall:

> Some buildings standing today still have wattle-and-daub panels from 700 years ago.

Will any drywalled building survive even a tenth of this time?

> The plaster mixture used then was a homegrown concoction, with recipes matching the climate needs and vernacular material availability.

The wonder of wattle-and-daub (clay) and plaster-and-lath (lime) is that the materials are breathable, move with the structure, and can even self-repair small cracks. I don't know of any old house that suffers from black mold...

My last big gripe with gypsum drywall is disposal. Demolish a property with clay or lime walls, and they'll naturally degrade into the environment. Drywall needs proper disposal: "Do not burn: Drywall releases toxic fumes. Do not bury: It can create dangerous hydrogen sulfide gas in landfill."

Does anyone want to live with that?

Definitely not a bot or ai touched at all or ESL. And reading the comment as I wrote it, it definitely read oddly to me too!

I take a little offense to the low content. Maybe low effort, but I feel like the references were worthwhile and for a reply-less post (at the time) I thought soranews24 deserved more attention. It is very weird to me. It looks like a content farm or buzzfeed, but all the content seems relatively original and there’s a lot of it.
by kmoser | 2026-02-13 06:45:23+00:00
I wouldn't call it trivial. First you have to determine where to cut it; if you cut the wrong area you have to cut again. All the steps in repairing it either take time, are messy, or require some skill, and the time adds up (e.g. waiting for the patch to dry before you can sand; waiting for the primer to dry before you can paint; etc.).

And then you have to match the surrounding paint, which is all but impossible since even if you have the same color, the original will have likely faded over the years, making your newly applied coat a mismatch, so now you have to paint the entire wall (no fun when it's a big wall). And if you had wallpaper instead of paint, good luck to you unless you saved some extra scraps.

All in all, an access panel would make the job much simpler.

They could also cheat on the private set though. The frontier models presumably never leave the provider's datacenter. So either the frontier models aren't permitted to test on the private set, or the private set gets sent out to the datacenter.

But I think such quibbling largely misses the point. The goal is really just to guarantee that the test isn't unintentionally trained on. For that, semi-private is sufficient.

It is indeed how it's done in the UK. It's a bit of a cliché for British people to complain about American houses, but it's not that we don't have stud walls ourselves, it's just that we don't just go and paint directly on top of plasterboard. Both walls and ceilings are skimmed, with either plaster or shudder Artex. We also have dot and dab walls which are built from block, have a layer of plasterboard glued, leaving a ~6mm cavity, then skimmed with plaster.

This future would lead to bad actors stealing or buying the identity of other people, and making agents use those identities.

There is a precedent today: there is a shady business of "free" VPNs where the user installs a software that, besides working as a VPN, also allows the company to sell your bandwidth to scrappers that want to buy "residential proxies" to bypass blocks on automated requests. Most such users of free VPNs are unaware their connection is exploited like this, and unaware that if a bad actor uses their IP as "proxy", it may show up in server logs while associated to a crime (distributing illegal material, etc)

Even if it is in the T&Cs, this one feels like it wouldn’t actually hold up?

Expecting people to read those for most simple sign ups is already a high baseline, and Starbucks is not technically a banks and offers no consumer protections (FSCS or other), so that feels knowingly misleading, even if the total balances held are small per customer.

IANAL, of course.

What? This is basic human social skills.

It’s like when you don’t like someone’s friends but you’re not actually going to say that out loud. Instead you say “I'm just too tired to go out” — it’s a “diplomatic out.” Yes it’s a lie at face value but you leave people with their dignity while simultaneously signal your intent. Your friend, who presumably has social skills, picks up the subtext and you successfully communicate two layers of meaning with one sentence.

Press releases are the same thing.

Windows is also the "it just works" operating system, and it has hundreds of useful things you can only do through registry hacks.

It's not a very useful test.

I look at the good things about macOS over desktop linux like how cmd-c/v works across all apps, and it would be amazing if it were just a cli command to bridge the gap.

Made a sound effects plugin for Claude Code.

GLaDOS roasts you when your code breaks. JARVIS calmly confirms your deploys. Steve Jobs celebrates passing tests. A WoW Peon sighs at every prompt.

12 themes, 165+ sound files. Mix mode picks randomly across all of them.

Install:
/plugin marketplace add 6m1w/claude-sound-fx
/plugin install sound-fx@claude-sound-fx

Adding your own theme = a folder with MP3s and a manifest.json.

I don't think it's a meme. I'm not an AI doomer, but I can understand how AGI would be dangerous. In fact, I'm actually surprised that the argument isn't pretty obvious if you agree that AI agents do really confer productivity benefits.

The easiest way I can see it is: do you think it would be a good idea today to give some group you don't like - I dunno, North Korea or ISIS, or even just some joe schmoe who is actually Ted Kaczynski, a thousand instances of Claude Code to do whatever they want? You probably don't, which means you understand that AI can be used to cause some sort of damage.

Now extrapolate those feelings out 10 years. Would you give them 1000x whatever Claude Code is 10 years from now? Does that seem to be slightly dangerous? Certainly that idea feels a little leery to you? If so, congrats, you now understand the principles behind "AI leads to human extinction". Obviously, the probability that each of us assign to "human extinction caused by AI" depends very much on how steep the exponential curve climbs in the next 10 years. You probably don't have the graph climbing quite as steeply as Nick Bostrom does, but my personal feeling is even an AI agent in Feb 2026 is already a little dangerous in the wrong hands.

Everyone dies. And if your lifespan is 1400 years, you won't live for nearly 1400 years. OTOH, people with a 1400 year life expectancy are likely to be extremely risk averse in re anything that could conceivably threaten their lives ... and this would have consequences in re blackmail, kidnapping, muggings, capital punishment, and other societal matters.

Using a waffer sized chip doesn't sound great from a cost perspective when compared to using many smaller chips for inference. Yield will be much lower and prices higher.

Nevertheless, the actual price might not be very high if Cerebras doesn't apply an Nvidia level tax.

Agree w/ you on the model's tendency to butcher things. Performance wise, this almost feels like the GPT-OSS model.

I need to incorporate "risk of major failure" into bluey bench. Spark is a dangerous model. It doesnt strongly internalize the consequences of the commands that it runs, even on xhigh. As a result I'm observing a high tendency to run destructive commands.

For instance, I asked it to assign random numbers to the filename of the videos in my folder to run the bm. It accidentally deleted the files on most of the runs. The funniest part about it is that it comes back to you within a few seconds and says something like "Whoops, I have to keep it real, I just deleted the files in your folder."

I’m not sure that your customer exists.

If someone wanted to “invest in crypto”, they have already done it by now and probably thinking to get more than a single digit percentage return[0].

You are offering a 4%-7% return that is only slightly higher than the promotional interest by fintechs[1] (where the money, up to a value, is guaranteed by the government).

Why would your customer invest in your system instead of going directly to stocks/ETFs?

The people holding 10k€+ in cash/ bank savings account that I know are old, tech illiterate, afraid of investing, and oblivious to the effects of inflation. They simply store the money somewhere so they can use it later at a short notice.

With these people you have way too much friction with the Coinbase way. Even if you succeeded in convincing them they deserve yield, it will be hard to compete with investing tools that are integrated into their banking apps that show higher profits than you.

I've often found when receiving a clueless support response like this, it can be effective to just follow up with a polite request to forward the ticket to an engineer or developer. Usually the front-line csr simply hasn't understood the issue. In this case I would say something like,

"Yes, I managed to work around the issue by switching to my personal email address, but this bug is still preventing me from using my work email domain. If you could please forward the error log I included to a developer, it should help them resolve the issue. Thank you."

In the current age everyone can eat everything everywhere, apparently there are even people who fly their bread everyday from France to New York. So when we talk about food in some place, its usually about the general practices and not the possibilities.

For example the food in London is shitty even if you can find some of the best restaurants there. The problem with London is that you can't fit those restaurants into your daily routine, the default is a sad meal deal from Tesco or something.

> The unscientific regulation, and in some countries bans or practical stoppages and embargoes on approvals and research, of nuclear power under the guise of saving the environment has been probably the most environmentally destructive initiative ever to come about

Six days old, but of course this isn't true. The initiative to block the ascend of electric cars early 20th century to favor fossil interests has been incomparably more destructive.
