The rough numbers I can find are that the acid cloud layer is ~75km thick, which seems awfully long for any kind of tether that'll have to support its own weight. With the low pressure (~0.1 ATM) it'd also need to be a rather big balloon.

Further down, the ~100m/s (~220 mph) winds on the tether would likely try to drag everything sideways, scraping any probe across the landscape.

In what way is this a conspiracy theory or guilt by association? I don't think it is. (Except maybe the statement that he's an Israel citizen, though I think in this context it's a legit statement to make.)

The parent post explicitly makes two separate statements - 1. that he's an Israeli citizen, and 2. that he has questionable morals. I don't necessarily agree with the second statement, but it's explicitly not saying he's immoral because he's Israeli (guilt by association).

Thanks.

- Load balancing is easier because your connection is stateless. You don't have to connect to the same server when you reconnect. Your up traffic doesn't have to go to the same server as your down traffic. Websocket tend to come with a lot of connection context. With SSE you can easily kill nodes, and clients will reconnect to other nodes automatically.

- The compression is entirely optional. So when you don't need it don't use it. What's great about it though is it's built into the browser so you're not having to ship it to the client first.

- The connection limit of 6 is only applies to http1.1 not http2/3. If you are using SSE you'll want http2/3. But, generally you want http2/3 from your proxy/server to the browser anyway as it has a lot of performance/latency benefits (you'll want it for multiplexing your connection anyway).

- In my experience CPU/memory usage is lower than websockets. Obviously, some languages make them more ergonomic to use virtual/green threads (go, java, clojure). But, a decent async implementation can scale well too.

Honestly, and this is just an opinion, no I can't see when I would ever want to use websockets. Their reconnect mechanisms are just not reliable enough and their operational complexity isn't worth it. For me at least it's SSE or a proper gaming net code protocol over UDP. If your browser game works with websockets it will work with SSE.

The people holding the ETF and selling the option. If they had not sold the option, they would have benefited from the value rising, now they instead got (collectively) $2.5M.

If the price had stayed flat or dropped, they would of course still have the $2.5M.

The precision makes it look a lot like a crime, as trading on information that's not publicly available is illegal.

I agree with the last two paras, with the following addendum. I'm also pro-Israeli people, but I find their leadership (and the settlers) the same as Hamas. No different.

As for the first para, I have very close friends who have been harassed for expressing support for plight. If you are a university student in the US today and said exactly what I have said, you can be found guilty as a terrorist-sympathizer. I have been downvoted to hell on reddit and elsewhere for putting it as mildly as I did here.

2005 is basically the dark ages of the web. It’s pre Ajax and ie6 was the dominant browser. Using this as an argument is like saying apps aren’t suitable because the iPhone didn’t have an App Store until 2008.

> It’s not true because throwing a video file as a source on video tag has no information about the file being requested until the headers are pushed down.

And yet, if you stick a web server in front of a video and load it in chrome, you’ll see just that happening.

Anecdata: I can count only a few couples in my circle of friends - who mostly had kids in their late 30s and early 40s - who didn’t end up having long and sometimes heartbreaking IVF, copious miscarriages, kids with trisomy, and in our case, stillbirth.

I think part of the problem was an assumption that modern medicine around childbirth is actually better than it is, and thus delaying having kids is a safe choice.

I consider myself very lucky indeed to have two healthy sons and my advice to my eldest is to get on with having kids as soon as you’ve met the right person, ideally in your 20s…

I don't trust them at all. The amount of traffic to various domains is incredible coming out of their desktop apps.

But mostly, when they first started the subscription model I wasn't furious about it - until I realised I was stuck on a yearly plan, and I'm usually pretty good at detecting when I'm being tricked into that. A part of me doubts I was ever asked correctly.

No idea! Infuriatingly, it looks like Netlify just decided to put up a random password-protection wall for no apparent reason. Sorry about that—I'm trying to fix it now.

edit: apparently it was taken down due to violations of their ToS—although I'm struggling to see how a simple one-page static website discussing my mum's experience being banned from Facebook could possibly violate the ToS.

No, in XP you were essentially logged in as root 24/7 (assuming it was your machine), and any program -- including your browser -- was running as root too. I remember watching a talk about how stupidly easy it was to write rootkits for XP. "Drive-by viruses" were a thing, where a website could literally install a rootkit on your machine just by visiting it (usually taking advantage of some exploit in flash, java, or adobe reader). Vista flipped it, by disabling the admin account, so that in order to do something as admin you needed to "sudo" first. That alone put a stop to tons of viruses.
Show HN:Browser-based heart rate measurement using only phone sensors (SCG)
by moshael | 2025-04-12 08:11:30+00:00
We've built HeartScan.app, a free, browser-based solution that accurately measures your heart rate using only your smartphone's built-in accelerometer—no camera, no wearables, no app installation.

Unlike typical camera-based methods (photoplethysmography/PPG), HeartScan leverages seismocardiography (SCG), capturing mechanical vibrations from your heartbeat through your phone's sensors. With a neural network trained on over 500,000 user-contributed records, we've reached over 95% accuracy for cardiac phase (R-peak) detection, achieving medical-grade BPM estimation directly in your browser.

It's entirely frictionless: no login, ads, or paywalls. We aim to democratize heart monitoring globally, especially valuable in low-resource settings.

Would appreciate any feedback, questions, or ideas!

EC scientific expert here (occasionally judging FP7/8/Horizon 2020/Horizon Europe grants in multiple areas including AI). I also authored some bigger proposals, one rejected (score: 13/15) and one funded.

It is perhaps not a good idea to apply to that many in such a short time frame, unless you have nothing else to do: the individual efforts need to be really excellent to succeed, so focus should be on quality rather than quantity. Why? There is a funding threshold, and you can have 5 proposals that get 13/15 ("good enough to fund"), but you still don't get any of them funded because there enough competing grants with 15/15 score, and after they receive their funding, the pot of money is already empty (the funding is in order of merit).

In my experience, most applications that fail to get the perfect score required are incomplete: To get excellent scores it is vital to FULLY address ANYTHING mentioned in the call. And to squeeze all that into 40 pages is an art. (There are folks that provide consulting support, which I have not used yet, or you could collaborate with someone who has worked on the other side to learn more about what is important.)

While getting grant money remains hard, I was pleasantly suprised about the judging effort and the EC's personnel energy put into the evaluation process and in making it fair; for each call, their is a special rapporteur going around and documenting that everything that should be done gets done the way it should be, and the EC take great pains to find experts that are diverse across multiple dimensions (gender, country, industry/academia, seniority, field of expertise etc.).

Turns out most GMOs were fine but they actually allowed for a huge increase in the use of Roundup.

Roundup is wildly aggressive pesticide and a lot of GMOs were called “Roundup ready” crops, so they could absorb (in theory!) huge amounts of Roundup without being affected.

But the huge increase in the use of Roundup in America might be behind (according to some) the increase in neurocognitive disease.

In the US this was never a thought.

Ask HN: What's a surprisingly useful tech skill that's underrated today?
by Userrr | 2025-04-12 08:13:42+00:00
We often talk about mastering popular languages, frameworks, and AI tools. But what about the less-hyped skills that quietly make you 10x more effective?

For example:

Knowing how to write a custom shell script that replaces a SaaS tool

Building internal tools with no-code + cron + GitHub Actions

Understanding how to optimize a slow SQL query line-by-line

Crafting a bash one-liner that saves you hours every week

Using the command line like a superpower

I'm curious: What are the most underrated but highly valuable tech skills you've learned that more people should know about?

Would love to hear stories, examples, or even niche tools you swear by. Bonus points if it’s something you only discovered by accident or necessity, not through a tutorial.

While I was developing [foyer](https://github.com/foyer-rs/foyer), which is a hybrid in-memory and disk cache project in Rust. Some users asked for metrics system support for both the Prometheus ecosystem and OpenTelemetry ecosystem. After investigating and trying out some libs, I decided to develop a new lib that is lightweight, support both Prometheus and OpenTelemety, and even different version of `prometheus`, `prometheus-client` and `opentelemetry` crates for various users.

I agree that laptop hardware compatibility on Linux is not the best but it can work if you buy the right device. Thinkpads are particularly well supported. You might also want to try a more up to date Linux distribution like Fedora. I never had problems with Fedora on my laptops but for example OpenSUSE Thumbleweed wouldn’t sleep properly for me and had broken Thunderbolt support.

This is the American position. “If you can’t prove it’s bad now, it should be legal immediately”.

Europe food regulation runs on the precautionary principle. You have to prove it’s safe first.

I am beginning to see this increasingly. Apps that make the most basic of mistakes. Some new framework trying to fix something that was already fixed by the previous 3 frameworks. UX designs making no sense or giving errors that used to be solved. From small outfits (that’s fair) to multi billion dollar companies (you should know better) , I feel that rigor is definitely lacking.

The amount of people in the startup world infected by the American Dream-Logic of privatization and Anarcho-capitalism always astounds me.

All I know and have in my life is thanks to public funding. Social Democracy works and is good for business too. A state with little financial regulation in the end also has less power and control sum total.

Since the southern US basically survives off slave laborers with no paperwork and giving any normal human decency to those people would probably lower the Murican standard of living I have low hopes for change. Here in the EU we screwed ourselves too haha. No one really looks out for the little guy anymore.

This is definitely not true, the issue is in the non-optimized software. I tried SXMo [0] on a Pinephone (which is much slower than the Librem), and it was unbelievably fast, including watching videos and looking a maps in a split-screen mode, simultaneously and smoothly. Android had 10 years and a huge team of developers to optimize the UI.

Because last year ...

> Adobe knowingly "trapped" customers into annual subscriptions, the FTC alleged.

> Adobe prioritized profits while spending years ignoring numerous complaints from users struggling to cancel costly subscriptions without incurring hefty hidden fees, the US Federal Trade Commission (FTC) alleged in a lawsuit Monday.

> According to the FTC, Adobe knew that canceling subscriptions was hard but determined that it would hurt revenue to make canceling any easier, so Adobe never changed the "convoluted" process. Even when the FTC launched a probe in 2022 specifically indicating that Adobe's practices may be illegal, Adobe did nothing to address the alleged harm to consumers, the FTC complaint noted. Adobe also "provides no refunds or only partial refunds to some subscribers who incur charges after an attempted, unsuccessful cancellation."

You can have microsecond updated, once the connection is established you can stream. Regardless of your latency.

Say your ping is 100 (units are irrelevant here). It will take you 100 before you see your first byte but if the server is sending updates down that connection you will have data at whatever rate the server can send data. Say the server sends every 10.

Then you will have updates on the client at 100 110 120 130 etc.

> Gemini 2.5 Pro in Deep Research mode is twice as good as OpenAI’s Deep Research

That matches my impression. For the past month or two, I have been running informal side-by-side tests of the Deep Research products from OpenAI, Perplexity, and Google. OpenAI was clearly winning—more complete and incisive, and no hallucinated sources that I noticed.

That changed a few days ago, when Google switched their Deep Research over to Gemini 2.5 Pro Experimental. While OpenAI’s and Perplexity’s reports are still pretty good, Google’s usually seem deeper, more complete, and more incisive.

My prompting technique, by the way, is to first explain to a regular model the problem I’m interested in and ask it to write a full prompt that can be given to a reasoning LLM that can search the web. I check the suggested prompt, make a change or two, and then feed it to the Deep Research models.

One thing I’ve been playing with is asking for reports that discuss and connect three disparate topics. Below are the reports that the three Deep Research models gave me just now on surrealism, Freudian dream theory, and AI image prompt engineering. Deciding which is best is left as an exercise to the reader.

I wouldn't even say Gemini Pro 2.5 is the best model. Certainly not when you do multimodal or function calling, which is what actually matters in industry applications. Plain chatbots are nice, but I don't think they will decide who wins the race. Google is also no longer in the mindset to really innovate. You'll hear surprisingly similar POVs from ex-Googlers and ex-OpenAI guys. I'd actually say OpenAI still has an edge in terms of culture, even through it fell deep.

This reads as FUD. I'm an American who's lived in Germany recently. On every measure, my experience was been better than the US.

I can walk to the grocery. Or ride a bike. Or take the bus. Or take the train into the city. There are options in transport and in the stores. Never, ever had those options in the States.

Yes, I've had some doctors I didn't care for. So I found another one and they've been great. Same thing happens in the States. You must advocate for yourself. Nothing different.

The big difference is the complete lack of fear going in because you know you won't have to pay an arm and a leg. And yes, it's not "free". It comes out of your paycheck. 110% better. Never had to wait an excessive time, even for specialists. No more than in the States; you schedule it out. Yet, I can go to the emergency room when there's a concern and be greeted with compassion and receive care. So much better, it's hard to convey and hard for Americans to believe. I didn't until I lived there.

As for "digitalization", yeah, it'd be nice to submit some forms online rather than through paper. But it's not a big deal. Howwver, it's super nice to talk to human beings on the phone! Haven't run into too many "your call is very important to us. Please listen as our menu may have changed" and then have to deal with a 1kbsp mega compressed audio line. Also, while I've had bad experiences with clerks, many more have been very patient and gracious. Again, contrast that to the DMV. Not much difference.

Doctors in the US also deal with tons of paper work...has your friend also worked in the States?

I just don't get how Adobe didn't get dethroned after being so unpopular for so long. There are so many Photoshop competitors, many of which are quite good, they seem to be ripe for disruption. The last version I used was CS6, which came out more than a decade ago, and even that had more than a good enough feature set.

Blender is slowly taking over 3D, why can't 2D be disrupted similarly?

> Hamas has broken ever cease fire since they took power.

Israel has broken every ceasefire, though US media tends to treat Israeli attacks as hiccups and challenges to ceasefires involving Israel and those on the other side as more serious. This is similar to the way that the same linguistic cause/effect separation (sometimes termed the “exonerative tense” or “exonerative mood”) frequently used to deflect responsibility for domestic police violence to Israeli military actions, but not to their opponents on any side.

One cool hacky thing you can do on Android is to get access to what music is currently playing on the phone (i.e. what Spotify song is playing, or any other music app).

The second cool thing you can do on Android is to have a bubble app to overlays on the screen on top of all apps. Once clicked, it can expand or collapse.

So, I built a bubble app that listens to what song is currently playing on the phone, asks ChatGPT to get fun trivia and insights about the song and displays them to the user. With one click on the bubble, you can instantly get behind-the-song info and elevate your music listening experience!

It's called MusicAI Bubble. It's free. Again, it works with any music app on your phone (Spotify, Apple Music, TIDAL, etc).

What more features would you like to see in such an app?

> I think soon people expect this service to be provided for free and ads would become the main option to make money out of chatbots.

I also think adtech corrupting AI as well is inevitable, but I dread for that future. Chatbots are much more personal than websites, and users are expected to give them deeply personal data. Their output containing ads would be far more effective at psychological manipulation than traditional ads are. It would also be far more profitable, so I'm sure that marketers are salivating at this opportunity, and adtech masterminds are hard at work to make this a reality already.

The repercussions of this will be much greater than we can imagine. I would love to be wrong, so I'm open to being convinced otherwise.

I sincerely appreciate the reply, but are you talking about Moore's law? Alexnet could run on a commercially available GPU in 2011(?). But that wasn't the peak compute platform being used at the time for DL inference, so it distorts the progress a bit. It's like me saying I was running a neural net on a raspberry pi yesterday for written character recognition on MNIST and today crunching stable diffusion on a GTX3090. Behold, a trillion-fold leap in just a day (nevermind the unrelated applications). The singularity is definitely gonna happen tomorrow!

But let's take for granted that we are putting exponential scaling to good use in terms of compute resources. It looks like we are seeing sublinear performance improvements on actual benchmarks[1]. Either way it seems optimistic at best to conclude that 1000x more compute would yield even 10x better results in most domains.

Is it just my computer or do others also have huge performance problems in somewhat large chats in AI Studio?

They really need to fix this.

It gets to a point where on each submit Google Chrome pops up a "wait | close tab" dialog.

I then have to use AI Studio for the "big picture" in one tab and ChatGPT in the smaller subtasks which help with the big picture.
