Novamin toothpaste is only sold & mfg in the UK. There are some conspiracy theories going around that the ingredient is so good they won't sell it to us in the US! [1]

I actually buy it off Amazon and use it myself because I have teeth sensitivity and it contains no SLS, which causes some irritation for me. It is quite interesting stuff. I doubt it would have lead since a synthetic compound. [2]

I wonder how much of this will just encourage protests and radicalization. If your agent is trained to match a profile of a radical, then it necessarily is spreading and encouraging that radical messaging in order to fit in and gain trust. At least with real agents there is a plausible mechanism for their judgement to filter out who is targeted and they can't infinitely propagate like the AI could.

Because lookup tables are not necessarily faster compared to 8-bit SIMD operations, at least when implemented naïvely.

Lookup tables can be fast, but it's not simpler, see T-MAC https://arxiv.org/abs/2407.00088 (Note that all comparisons with `llama.cpp` were made before I introduced the types from https://github.com/ggml-org/llama.cpp/pull/8151 where the 1.6-bit type uses the techniques described in the aforementioned blog post).

I wanted to try without lookup tables to at least have a baseline, and also because the fixed point packing idea lent itself naturally to using multiplications by powers of 3 when unpacking.
Ask HN: For LLMs, Create a cultural, palatable norm of noting sarcasm?
by thimkerbell | 2025-04-17 14:35:07+00:00
Does anyone else feel inhibited about making a not-to-be-taken-literally comment for fear the LLMs will imbibe it? What is the palatable fix for this? (and if a good one, could HN become a leader in its promulgation?) (/s is ugly (unpalatable) to most who write/read the comments, sadly, in a "do i have to spell it out for you" weary way.)

That's more or less what I've been doing lately. It's great at first stage rubber ducking, and very occasionally my problem is common enough that it already has the solution in the database.

Probably more than half the time I use the LLM to barf up the right keywords then search for the answer myself.

Since my job right now is "try to cover for ten missing employees" it's been vital to staying productive. Along with a general focus on efficient processes, I've managed to get my workflow pretty fast.

Interestingly, my Mom's parents owned both an icebox and a quite modern electric refrigerator (1980s).

The icebox was kept in a carpeted room and it was used for dry storage. We never put ice in it. And it was definitely called "the icebox". But also, Grandma referred to the refrigerator as "the icebox" as well, and we always knew what she meant, because she'd typically say "put that milk in the icebox" or whatever to refrigerate the stuff.

Grandma had the best kitchen with the most fascinating appliances and gadgets. She had a flour sifter, an eggbeater or two, an actual breadbox (have you ever heard the question, "is it bigger than a breadbox?"). Our other grandparents were the first ones on the block to purchase a microwave oven. They hoisted it on top of the refrigerator and we could barely reach into it! My cousin said not to look into the microwave while it was cooking because it'd cook our eyeballs!

I mean I agree about Tramiel management. I was an Atari ST user from 86? 87? to 92.

But I also think there's just no way Atari Corp could have taken on e.g. Apple regardless of management. They simply didn't have the capital, market penetration, etc. to carve out a segment that big. Apple was already a big deal and although the Macintosh was not really a big success at that point, there was a giant company behind it with top tier talent, and lots of cash.

TikTok isn’t doing much that our domestic social media overlords aren’t doing to us themselves. Yeah Facebook is for boomers and Instagram is for millennials, but they’re only targeting the platforms like that because TikTok has already seized the younger demographics. If it wasn’t there they’re be on a Meta, Snap, YouTube, or Twitch app instead and still having their brains rotted.

We need actual data privacy laws that make that business model of invasive surveillance capitalism non-viable as well as some of severe regulations placed on algorithmic recommendation engines to limit these harms. At the very least, users should be permitted to tune their algorithm parameters, including deciding how much they see things they’ve explicitly requested to see less of.

Yeah we can scaremonger about TikTok all we want, but it’s not solely TikTok’s fault that it’s trash. The economic incentive structure is to produce a surfeit of brainwashing trash that erodes people’s mental health. We need to structurally change privacy laws and force market competition to crack these network effect monopolies if we want that to stop.

You've taken something from a fun thought exercise to "why are you executing on this!?" We're just having fun, but I encourage anyone to freely take the idea and run with it. The world is a big place.

Note the concern you share, which shows how far we've slid towards said authoritarianism. If you're afraid to even talk about it, the damage done is evident. Fear is a feeling, danger is objective.

Is Guile really that good at the shell scripting "thing"? Like, the bash superpower is that it makes it extremely easy to run subprocesses in incredibly flexible ways (in the background, foreground, in pipelines, with stdout/stderr redirected to files, etc. etc.). Can Guile do that smoothly? I generally find that doing things like this is way more awkward in most "real" programming languages compared to shell scripting languages.

It looks like Huang got shafted by Trump and this is retaliation. The timeline of events is:

* Huang attends million dollar Mar-a-lago dinner

* Trump admin says it will allow H20 sales to China

* Nvidia announces $500 billion investment in US AI infra construction

* Trump admin 180s and bans H20 sales to China

* Huang unexpectedly shows up in China.
by afavour | 2025-04-17 14:37:41+00:00
Every time there's a post like this on HN ("social media app harms children") responses like this seem to be a primary response. It always feels like handwavey avoidance of addressing the actual issue at hand: harm to children. "Oh so it's only bad because the Chinese own it? You're okay with American propaganda?!??"

"TikTok Is Harming Children at an Industrial Scale" does not imply "Instagram Is Not Harming Children at an Industrial Scale". It is simply studying one app. There have been numerous reports of the dangers Instagram poses (especially to teens), and when they get posted we get a raft of "why just pick on Instagram?" comments. It's tedious.

> I wish Americans still believed in American freedoms

I wish people understood the American system at a philosophical level. What you call "American freedoms" are largely based off of negative rights, i.e. John Locke. Our bill of rights use specific language like "Congress shall make no law", "shall not be infringed", "shall not be violated". It's inherently freedom from state action.

Over the past 100 years a different interpretation of rights has emerged, so called positive rights as exemplified in FDRs second bill of rights; e.g. "the right to a good education" or "the right to earn enough to provide adequate food and clothing and recreation". This requires state action to facilitate freedoms for its citizens.

Unfortunately these systems are incompatible. I think a lot of the friction we are seeing in modern times can partially be traced to this contradiction.

Markmonitor is much more about the people and service behind it rather than the software. To replace markmonitor you don't need a dev to write a tool. You need a dev to write a tool, and then a team of people who build relationships with everyone in the domain world and are available 24/7 to make calls and deal with issues if they come up.

My opinion is that TikTok is vengeance for the Opium Wars and the Century of Humiliation.

Internally, China protects its kids:

I can't compare levels of evil, however. I don't think anyone, in good faith, can, since it depends on your value system.

Show HN: Dapto – Real-Time Firewall for AI Prompts and Responses
by sharmasachin98 | 2025-04-17 14:39:34+00:00
Most companies are excited about GenAI, but scared to use it.

Why? Because they have no control over what the AI sees, says, or shares.

We kept seeing this problem in enterprise GenAI rollouts. Tools like GPT or Claude are getting embedded into dashboards, chatbots, and workflows, but there are no guardrails in place.

So we built Dapto. A drop-in firewall that sits between users and the model. It intercepts every prompt and response, blocks prompt injection and hallucinations, masks PII and sensitive content, and adds full logs, metadata, and risk scoring.

It works out of the box with OpenAI, Claude, Gemini, Ollama, and LangChain. No need to modify your model or application.

Here’s a short demo: https://youtu.be/dxFb7Q12gcw

We’re looking for feedback, early pilots, and brutal honesty.

Would this fit into your stack?

This is Jonathan Haidt, and he's been writing against all social media for years now. This article is about TikTok, but a quick stroll through the archives shows they released an identically-titled article about SnapChat yesterday:

https://www.afterbabel.com/p/industrial-scale-snapchat

The archive also includes a bunch of articles on social media in general, edtech, and similar.

The first link in the article contains PPM, and if you click through it lists % actionable levels for the individual brands / contaminants:

https://tamararubin.com/2025/01/toothpaste-chart/

Maybe HN should just link to this?

Incidentally, apparently, they test based on donations from their reader base. Most of their readers are interested in weird fluoride-free stuff.

If you want them to test more mainstream brands, you can send them money:

https://tamararubin.com/2025/02/lead-safe-mama-llc-fundraise...

I'm not endorsing them, and have no idea how well they conduct their tests, etc. There might be a better way to fund independent testing of consumer products.

I think more harm is being done by everyone retreating to their own echo chambers, and being unwilling to have their views challenged; then they forget how to discuss things rationally and reach a compromise.

This also applies to parenting, which is why people instead turn to products such as these and insane privacy-destroying laws, instead of... talking to their children; developing a trusting relationship with their child where the child can talk to their parent (and vice versa) about what they're seeing online, what they believe, etc.

I bought an XBOX One as opposed to a PS4 because I'd heard the Plex client was perfect on XBOX -- personally I like game consoles as media players because they play discs and I'd rather have an overpowered rather than underpowered machine.

I ditched Plex when they came out with a FAST [1] service which was thoroughly pizzled [2] for me. I switched to Jellyfin which I struggled with in so many ways, the terrible XBOX client which was a degraded version of the web client was the worse but Jellyfin's poor metadata handling was part of it.

Last summer I spent a lot of time in a room in our rental house where I tried (and failed) to gentle a feral cat and wound up watching a lot of Tubi and came to the conclusion that FAST wasn't so bad and gave Plex another chance when I rebuilt my home server and I can say I'm highly satisfied.

3FS isn't particularly fast in mdbench, though. Maybe our FDB tuning skill is what to blame, or FUSE, I don't know, but it doesn't really matter.

The truly amazing part for me is combining NVMe SSD + RDMA + supports reading a huge batch of random offsets from a few already opened huge files efficiently. This is how you get your training boxes consuming 20~30GiB/s (and roughly 4 million IOPS).

Sure, but when everyone else uses the upvote/downvote button that way it doesn’t matter how you personally use it. The end result is anything that goes against the hivemind gets suppressed.

I’ve had fully scientifically sourced rebukes of things (effectively, straight up facts) get downvoted to oblivion on Reddit. Hundreds or thousands of people didn’t see that their preconceived notions were probably wrong. It’s no wonder politics has become more insular.

HN is better than most, thankfully.

> The main reason TikTok is being targeted is because it doesn't silence pro-Palestinian perspectives on the conflict.

First of all, TikTok was being in the crosshairs ever before Hamas decided to slaughter and take hostage civilians on Oct 7th.

Second, why is it always the pro-Palestine crowd that acts like their issue is the most important thing in the world, completely de-railing any debate? Seriously, no other geopolitical conflict has so many people injecting it into any debate they can find.

even a monkey can act by flinging faeces at random. you are proud of things you should feel shame about. It takes a special kind of "genius" to look at established things and not consider that half a century+ of bipartisan leadership may have considered getting rid of those things but knew better.

You're like a wealthy person burning down his fancy cars, and his property because the servants used it. Not caring your wealth and pride is tied up in those things.

It doesn't appear to be random. I once made that offer to a woman who hardly knew me, joking not joking, and she took it as a compliment, as intended, but alas she declined. I assume that my batting average would be better if I were very rich. Or if I had social skills. Or If I wasn't repulsive.

But as I am socially retarded I'm not clear on when and why such an offer is not OK. I am willing to be educated. In terms of the golden rule it seems to pass validation, as I would be honored (and shocked) to be asked to father a child for a stranger.

Absolutely agree, AI's rapid evolution is making high-quality data more valuable than ever. As the saying goes, "data is the new gold," and in the AI race, it's the sharpest competitive edge. While LLMs are getting better at automating scraping tasks, they're not perfect yet—so reliable, precise data collection is still critical. Teams building AI tools need solid scraping pipelines to stay ahead, and in 2025, that’s becoming less of a nice-to-have and more of a must-have.

You're welcome. The Android app is pretty good, but for iOS it remains unreleased, so you have to deploy yourself. Prologue seems to be the best iOS App.

I feel like this is a site full of educated people, for whom a citation for this claim is about as necessary as one for the claim "the President is the leader of the executive branch of the US government"

Honestly, I question the motivations of any techie trying to argue that a Chinese state-controlled propaganda machine consumed en masse by children is anything but especially problematic.
by mjburgess | 2025-04-17 14:42:43+00:00
The problem becomes when the president does it; and how he does it.

Since the president has vast formal and informal powers, any use of his power to achieve a totalisation of his ideology into society is "alarms going off territory".

When he has taken down the law firms, suspended the licenes of the media companies, sequestered the national guard against protestors, and deported political opponents --- at that stage, what will be left to protect you?

The president, as one man, cannot wield the full power of governmenrt -- this is tyranny. And, esp. cannot weild it against civil society, this is totalitarianism.

I sometimes wonder whether the end result of this proliferation of bots is the creation of a "premium" Internet where you are authenticated as a real person before entering. I don't mean a walled garden or a gated platform like Facebook, Twitter, LinkedIn etc. I mean some sort of application layer protocol running on top of TCP that has real world authentication built in. Any application built on top of that protocol is guaranteed to be used by only real human beings.

We've made the world run on machines, and gotten better about machine intelligence and distributing software, so the speed at which the world's machines can operate smarter has increased significantly.

An innovation by one person can be distributed to the majority of people on the planet within minutes. It's amazing and all of our social and political norms aren't built to handle this.

> Spotify can pull the plug on whatever your favorite song is and there is NOTHING you can do about it

There's plenty I can do about it. If Spotify decides to "pull the plug" on a song or artist I like, it's my prerogative to switch providers or decide to self-host. I'm not locked into a lifetime serfdom with them, and it's not like the files will magically vanish from the internet once Spotify decides not to host them.

> who will willfully consume the most crappy audio codec

I listen to 99% of my music through Bluetooth on AirPods, so 320kbps is perfectly fine for my use case. If I was someone who cared deeply about audio quality, I would switch to a competing service with HiFi.

> The arguments are "Protect the children.", "Catch terrorists.", "Catch criminals.".

> Those arguments have been engaged with for decades. They are purely emotional arguments. Anyone who still pushes those arguments forth is most likely doing so with ulterior motives and cannot be reasonably "engaged" with.

Oh come on. Why do you think a "purely emotional arguments" are illegitimate? Are you some galaxy brain, coldly observing humanity from some ivory tower constructed of pure software?

Nearly all positions people take are, at their core, "emotional." And the disagreements that result in "arguments" are often really about differing values and priorities. You might value your "freedom" more than anything and are willing to tolerate a lot of bad stuff to preserve strong encryption, some other guy might be so bothered by child sexual abuse that he wants to give it no encrypted corner to hide in. You're both being emotional.

Yeah, it's not "moronic propaganda", it's someone who has, historically and famously so, been very focused on the broad issue of social media's impacts focusing in on various specific aspects of it, of which TikTok is a part.

Humans can do _most_ of what you said in real time, both providers using bespoke software and club analysts using off the shelf stuff like Sportscode. For full positional data on every player, every frame then yes, computer vision is doing most of the work but the quality isn't always great. Providers with in-stadium multi-camera systems provide great data, but you don't necessarily have access to the size of dataset you'd want for recruitment, and so lower-quality broadcast tracking exists (with all the problems you can imagine like missing players, occlusions, crazy camerawork etc). Most clubs also have wearables for their own analysis. Almost every fully automated broadcast tracking solution has hit a wall (sometimes on the first day of a season) in terms of quality that is often only solved by human QA, or by just discarding some games, so this is far from a completely solved problem. Fun domain to work in, but lots of horrible edge cases.
by coldpie | 2025-04-17 14:43:32+00:00
Yeah, you're on the right track now. What you need to do next is provide evidence for your arguments:

> there is a ton of exposure that constitutes inappropriate risk

Like what? What are the harms that are caused by the too high level of risk?

> it can be mitigated reasonably

Can they? What would the cost to introduce the mitigations be? Are the harms solved worth the increased costs?

These are interesting questions and I 100% believe that there are good changes to be made here. But, a study showing that current products are already below a set risk threshold is not evidence that the risk threshold is too high. That requires a different kind of study & evidence.
