How'd that work out for SawStop? A tech that makes table saws basically safe by stopping the blade immediately on contact with water (simplified description). The inventory tried to license the tech, then tried to get regulatory agencies interested. He never had any luck. I imagine his licensing terms were too much; he ended up making his own line of saws which are substantially more expensive than the unsafe competition.

I'm sure there are tons of other examples. Outside of highly regulated areas, improving safety usually plays second fiddle to lowering price.

The only true reliable way is to burn more than you eat. Counting calories is a way to keep track of that, but it's only going to be so-so accurate unless you only eat labeled food. I will certainly not measure the weight of a banana I eat, and anything else is just a very rough estimate as a banana can be twice the size of another banana.

In general, when I was losing weight I did not really need to count calories, I just ate less than I did. And this worked because I was always hungry especially initially, until the body adapts. If you're always going to check "can I eat this one more thing dear calculator" I'd say you're not really ready to lose weight because tormenting yourself like this every day you will burn out before you can make a dent.

I don't really want to hash this same thing out for the... At least hundredth time. You're not going to convince me, I'm not going to convince you, and we'll both just leave less happy if we keep going.

>Whistleblowers can still encrypt documents on a flash drive, and drop it into a mailbox. There is nothing stopping them from doing so.

The only thing I want to highlight for your consideration is that the USA is not the entire world. The USPS, even if it were perfect, does not exist in the overwhelming majority of the world. People talk to people across borders.

(Also, with some of the proposed laws, encrypting the USB would be illegal)

Sure, the culture is the content and human drive behind it, but the technology has made it so that we cannot avoid it and cannot easily practice good hygiene when it comes to social engagement. Or another metaphor, food, imagine if you had candy/sugar laying around everywhere and that was placed in front of whole foods everywhere you looked, such that you technically could choose a better option, but you were always fighting your human instincts to prioritize fast/cheap energy. As an adult, you know that you need to override these base instincts, and have evidence from your childhood where you encountered the structure of choosing healthy options even when you probably wanted something more sugary/fatty. The argument is that kids are not getting the opportunity to develop this healthy digital content diet because their parents either do not have the technical ability nor the actual functional ability to do anything about it.

There's a reason why most teenagers are on tiktok, but believe that they would be better off if it never existed. [1] https://fortune.com/well/article/nearly-half-of-gen-zers-wis...

yesn't

codegen in the OP article is machine gode generation (i.e. running LLVM)

It's semantically kinda like having a single 100k file, but because rust knows it often generates huge "files" there is a splitting step, somewhere between parsing AST and generating machine code (I think after generating MIR but not fully sure). And the codgen-unit setting is in how many parts rust is allowed to split a thing which semantically is just one code unit. By default for release builds 16 (and as it can affect perf. of generated code it's not based on #cpus). But in there case there seems to be a bug which makes it effective more like 1! Which is much worse then it should be. (But also the statistic they show aren't sufficient to draw too much conclusions).

There wasn't much to them, but yes. The second comment asked a question which I'd already answered, which is why I'm wondering if you read it and followed the link to the article targeting Snapchat.

I can respond again if your attention span has been shot by too much TikTok:

> Then why isn't the article "Social Media Is Harming Children at an Industrial Scale?" USAID checks?

Because he already wrote many, many articles to that effect and wanted to write one on TikTok specifically. Then he followed it up with one on Snapchat specifically.

Social media harming children is his whole thing. He's written a lot of content on it.

Apologies if this reply is too long for you.

The crazy thing about the definition of NP-completeness is that Cook's theorem says that all problems in NP can be reduced in polynomial time to an NP-complete problem. So if a witness to a problem can be verified in polynomial time, it is by definition in NP and can be reduced to an NP-complete problem.

If I can verify a solution to this problem by finding a path in polynomial time, it is by definition in NP. The goal here was to present an example of a problem known to not be in NP.

> Haidt is not the world's most careful data analyst

This is a massive understatement. The ironic thing about Haidt is that his writing is heavily geared towards social media. He writes a good headline and usually has a few facts in there, but is fundamentally non-rigorous. It’s science for skimmers and people who clicked on an article already agreeing with the conclusions and so won’t challenge the “evidence” he provides no matter how weak.

It doesn't have to be your bank if you don't want, have the DMV be an issuer or your car insurance, or health insurance or cell phone service etc.

You choose which one you want you want to have assert your claim. They already know you. It's a better option than giving every random website or service all of your info and biometric data so you can 'like' memes or bother random people with DM's or whatever people do on those types of social media platforms

Kind of weird, because I use youtube premium, a LOT. I don't get anything political, or conspiracy theory. I do get WAY too many wood working suggestions, AI tech, and astrophysics stuff. However, these are at the expense of the other channels on topics that I've subscribed to, like body weight fitness, health nutrition, some music stuff.

The YouTube alg is obviously broken. By broken, it's optimized for monetary profit. I get tired of specifically having to search out my other channels that I subscribe to, that I'm contemplating giving up Premium, and only using it on an as needed basis, since I need to search for my workout channels anyway.

I think that's actually hard... because you have to know what the text is you're redacting to get the spacing for the letters right. You want to redact specific words, but keep the rest of the document the same. This means that you need to know the letters (and their order due to kerning).

The best way to redact a PDF is with a printer, a sharpie marker, and a scanner.

> then what are we really funding

A single mother than works at Walmart and another job delivering food, trying to support her kid(s), and will get let go if she misses a day at work; who is desperately trying to better herself so she can provide a better future for her family?

Look, I get that it's a balance between stopping the cheaters and not putting undue burden on the good ones. But it's not a simple problem, and there's a lot of people out there that are under constraints that a lot of us wouldn't even consider when trying to work out the solution.

I had just a conversation with parent who said she allows her kids to play videogames only because it's the only thing they are able to do with focus. At the same time she is worried that they seem to be unable to listen even 4-minute pop hits from start to finish. They only listen "best parts of hits" – intro, beginning of first chorus, bridge and skip to next piece.

In xonsh[0], that would be:

cd $HOME/media git ls-remote ...

(Not sure about the equivalent of shlex.quote, but in the worst case, you can just use "from shlex import quote as q" or something).

So yes, there are good alternatives to bash - even Python based.

That is not at all the primary point of this article. This article focuses nearly entirely on the damage done by TikTok as a social media application, very much in keeping with the exact same criticisms the author makes of other social media. It focuses very little on the national security implications of Chinese ownership.

Personally, I think the national security argument is the much stronger one for the divestment bill (which the current administration is illegally refusing to enforce at the moment). But that's just not what this author cares most about.

> You are suggesting that family courts in Colorado should be barred from hearing info from psychologists about the impact of dead-naming?

Classic strawman argument. Where was anything like this suggested? Are they barred today under existing legislation?

The eventuality of this line of reasoning is that: "special interests who control the DSM (or whatever standards body governs these soft sciences) can influence and determine the outcome of custody battles."

DSM-4 defined "gender-identity disorder" as a thing, that's now been de-pathologized to "gender dysphoria."

Under your framework, a body of unelected, politically and financially-motivated "experts" can now determine the imposition of legal consequences on a whim.
Show HN News v2: Ad Free Newsfeed - All News, No Ads
by codebydom | 2025-04-17 15:14:18+00:00
Hello,

I built a simple ad free news website after growing frustrated trying to get my news from news websites filled with ads or social media platforms filled with distractions.

I was looking for a news website that gave me literally just the news in a simple - distraction free platform. But could not find a solution that satisfied what I was looking for - so I started building one.

Over last couple of months I developed newsv2.com - a website that is just news with no ads, no images, just headlines and basic descriptions.

The headline based news feed is free and you can use it today and I would appreciate your feedback

60-70% of people just read headlines when getting their news so just presenting those alone should keep people informed but would like to hear your thoughts.

I find myself using newsv2.com/live everyday for my news - and am very happy with it and I finally have a way to get my news without having to go on social media or news websites.

You can also test out the audio visualizer i built into the app for free at newsv2.com/audio - you can visualize audio from youtube videos with it by sharing your browser tab with the visualizer or audio from your mic - just a fun feature.

Also just so you know there are also optional AI features as well, while not the focus of this post, if you are interested (you can use for Free for First month with code PH100 at checkout with 100-200 Credits per month Subscription - cancel anytime)(Note: requires sign up and is not focus on post but just wanted to clarify)

Not looking to sell subscriptions more so looking for feedback and want to give users a way to test those features if they're interested for Free.

I'm also never going to put ads on this site - site is focused on users first and would greatly appreciate feedback to improve it.

Please send feedback or any questions to news@newsv2.com, thanks!

interesting - I think I have to side with the Boundary (YC W23) folks on this one - if you want bleeding edge performance, you need to be able to open the box and hack on the insides.

I don't agree fully with this article https://www.chrismdp.com/beyond-prompting/ but the comparison of punchards -> assembly -> c -> higher langs is quite useful here

I just don't know when we'll get the right abstraction - i don't think langchain or dspy are the "C programming language" of AI yet (they could get there!).

For now I'll stick to my "close to the metal" workbench where I can inspect tokens, reorder special tokens like system/user/JSON, and dynamically keep up with the idiosyncrasies of new models without being locked up waiting for library support.

I think the tech has raised stimulation levels exponentially, which feeds people's desire to consume in ways that was impossible in the past. But, I also think your examples are quite valid, and what we're seeing here now is probably only marginally worse than Neil Postman days back in the '80s and '70s when TV was the big boogeyman. Meaning that our society has already been screwed for half a century, and we should probably try to look at the problem through this lens rather than just trying to turn back the clock by a mere decade or two.

Maybe things were already bad when radio achieved mass adoption and people couldn't get enough of it? Maybe in some ways today's unlimited aural stimulation, of having access to music and podcasts at any moment, is also unnatural and undesirable for mental health?

> The author just want a medal saying they're Technical. Whatever this means, it is important to them.

I don't think that's quite it.

> I guess technical is "techbros and their salary"

That is it, from what I can tell. "Technical" is "you get US coastal techbro power and money". Which, most "technical" (lower-case) people working in computing also don't get, even in the US.

This author wants sciency work in fields with more women in them than computing has, to be valued in terms of pay and prestige as capital-T "Technical", and defines "Technical" such that people deciding who gets that pay are somehow within it (rather than very much not within it, as would be the case for most of the category I think the median HN user would call lower-case t "technical", which is part of why so much of the essay is hard to follow until you've figured that out)

This is why the piece is so hard to follow: this isn't made clear until way down near the bottom.

I actually read your comment while still around the halfway mark of the piece, and assumed it was reductive and way off the mark, but I think you've located the actual heart of it, now that I've finished reading it.

The methods being described in the articles are not what I have been doing. Those are for acute high dose metal poisoning and are very dangerous even when they are truly required. Even the oral versions I use warn not to use them long term for the reasons stated in the articles. If people are getting IV high dose chelation as a method of therapy then yes I would agree that is dangerous and reckless behavior of whatever doctors are doing this. That would be akin to getting TPA shots for therapeutic reduction of arterial plaque.

I used my methods on and off watching my BP over a period of time and watched for the valley floor.

You are completely correct. I'm watching the same thing happen to my little cousin. Please hear me: take the phones and take the computers and take the ipads and make them go play outside. We do this when my cousin visits and it's amazing how quickly he shapes up. But there will be a point at which it's gone too far and the damage is much harder to repair.

You can youtube-dl whatever is good and stick it on a raspberry pi running kodi with no internet. You can get them el cheapo kindles and load them up with all the books they could ever read. You can let them use computers supervised for khanacademy. But please, as the rare adult who's aware of and cares about this issue, don't let your kids fall victim to it.

I keep important data on a zpool that's mirrored across 2 drives, I snapshot it nightly, zfs send/receive the snapshot a drive on a different machine, and run a borgmatic/borg backup to borgbase 3 times a week. I also run a scrub on it quarterly.

So I effectively have multiple layers of backups.

Haidt is equally as famous for skipping any research & data gathering, cherry picking unserious "research" from his allies & often himself to write the books/articles/propaganda. https://3quarksdaily.com/3quarksdaily/2024/07/why-academics-...

The damned site he writes under is called After Babel! His identity at its core is linked to not just convincing but aggravating agitating and hyping an image of the world made "anxious" and depressed by devices.

There's a lot of other causes for the world being as unsupportive as it is. As a society we are losing meaningful connection to work, by having such vast mega corps sucking up all the work, managing the world from the top down. The concentration of capital has had enormously brutal impacts on the human spirit. But you won't see Haidt acknowledge or concern himself with what else is unravelling the human fabric.

There's some directionally correct concerns Haidt has, but as someone whose made it his calling to drive a wedge into what society is & demand a conservatism against the new, stridently & loudly, with no bones about what comes very close to lying, I cannot help but detest him deeply.
Show HN: Zuni (YC S24) – AI Copilot for the Browser
by willgtaylor | 2025-04-17 15:15:39+00:00
Hi HN,

I'm Will, and along with my co-founder George, we've built Zuni (https://zuni.app) - a browser extension that adds contextual AI capabilities to your browser. It understands what you're reading and working on, whether that's email, research, or anything else in your tabs.

We started out building a full email client with AI built in (you might have seen that version showcased in YC’s AI Design Review - https://www.youtube.com/watch?v=DBhSfROq3wU&t=1601s), but learned that people don't actually want to leave their existing tools - they just want them to work better. Gmail might be frustrating, but it has years of features people rely on. So we pivoted to enhance the tools people already use, rather than replace them entirely.

Some specific things Zuni does today:

- Analyzes emails as you read them in Gmail, identifying action items and suggesting possible responses - Lets you discuss how to handle tricky emails, almost like having a thought partner - Maintains context across your browsing session so you can ask follow-up questions naturally - Runs locally first for speed and privacy - Doesn't store chats, emails or anything sensitive in the cloud

We're still early and focusing on getting the core experience right before adding more integrations. The goal is to make AI actually useful in your daily work, rather than just another "AI feature" checkbox.

Would genuinely love feedback from the HN community - what would make this truly useful for your workflow? What are we missing?

Happy to answer any questions about the technical implementation too.

> If TikTok gets banned and some slightly more benevolent version takes it place

I don't have TikTok on my phone. I don't have an account. But I have YouTube, Twitter, Instagram all locked down on my phone (my SO has the Screen Time code).

I did this because the best minds on earth get paid based on how much I doom scroll. If I don't do this, I routinely have times where I scroll for an hour+.

I have argued that the only solution to this is to either ban any sort compensation based on increased engagement of a social media product (probably impossible to enforce or unconstitutional if that still matters). OR to add regulation around infinite video scrolling. We regulate gambling because it hacks our dopamine loop (although usually associated with much more severe consequences). I think it's ok to regulate the video scroll. Start small with something like enforcing a scroll lock after 30 minutes. To enforce it, just regulate the largest companies.

It's a bit hard to give "typical" costs because it's so dependent on how you use it. The project map size (which scales with overall project size) and the number/size of relevant files are the main drivers of cost, so working in large existing codebases will be a lot more expensive than generating a new app from scratch.

Taking Plandex's codebase as an example, it's certainly not huge but is getting to be decent-sized—I just ran a count and it's at about 200k lines (mostly Go), which translates to a project map of ~43k tokens. I have a task in progress right now to add a json config file for model settings and other project settings. To get to a pretty good initial version of this feature, I first did a fair amount of back-and-forth in 'chat mode' to pin down the details (maybe 10 or so prompts) and then an implementation phase where ~15 files were updated. The cost so far is at a little under $10.

I haven't conflated them, it's just that it's required that you misunderstand in order to continue on with the fiction that the youth owe you the money you paid into our elders. That doesn't make any sense. Your premise that you're getting back what you paid in only makes sense if you look at it that you actually paid something into the people paying you, which in practice is the investment in the youth becoming productive. Which you definitely do, just on average non-parents do not do it as much as parents.

It just does not make any sense whatsoever non-parents would get the same stake in SS that parents do. It makes 0 sense at all, as the system is currently set up, and I suspect is responsible for a large part of the moral hazard where people grab SS made possible by investment in children but reject children, basicaly renegging the investment but grabbing the dividends. This is part of the reason why I think SS is a broken system, and as we are finding out is likely destined for bankruptcy as the population pyramid inverts.

Brings back a lot of memories. I worked at K-Mart when I was in high school. I recall in 1983 when the TI-99/4A was discontinued, and the Sunday morning when we were selling them for (I think) $50 with a $100 mail-in rebate. When the doors opened people sprinted down the midway aisle to the TV/electronics department at the rear of the store where the computers were. I was an Atari snob at the time and had no interest in one for myself. I think we had less than a dozen in stock.

I see your point, but I dont agree with your metaphors at all.

Governments around thwe world have had to tax sugary products to save people from themselves. You make it sound like there isnt currently an obesity epidemic because adults know enough to not eat too much sugary foods. In reality the vast majority eat way too much even though they know its not good for them, just like social media use. Its the same as alcohol and drug abuse etc. Humans are terrible at restricting themselves when it comes to stuff that makes them feel good. Tiktok scrolling is just an extension of that, not the cause.

Your quote for that FDA standard is for water, which is consumed by typical people at a level around 1000mL/day (varies widely). The testing is done on toothpaste, which is not consumed at all when used correctly, and even if directly swallowed would be something around a 100mL tube every few months, so 2-3 orders of magnitude less exposure at worst.

Which would put even the most contaminated products in their chart at the "safer than water" level.

I think it's fair to say we're looking at junk science here.
