> For investments, I think now "buying index" will stop working well and buying chosen quality, profitable companies will work much better. My 2c.

Eh, that's what the index should be comprised of anyway, with some lags.

Or, to put it differently, nothing new: it was always much better, if you knew which companies will exceed expectations. After they do so consistently, they get included in the index eventually.

This theory is highly generalized. Depending on context any critical resource may become precious as a result of economic problems and social disparity. Sometimes it is food, other times housing, and so on. And these triggers are differentiated from the structural issues that generate critical instability in the first place. What spreads kindling around may be unrelated to what strikes the match.

Memories are about density. I my memory isn't playing tricks with me, a TCAM is about ~300-400F^2 where F is the feature size of the node. On a per bit level, that means that this bit is 4E^10 bigger.

Put another way, the TLB in a CPU is relatively small and definitely a hotspot but you could estimate the TLB in a CPU at ≈ 0.0003 – 0.002 mm^2. which is ~50 times smaller then the single bit in this paper. To get to 10GHz we could just make 10 copies of an existing TLB operating at 1GHz and still have a ton of headroom. There is also a electro-optical conversion penalty that you need to take into account with most optical systems.

Not trying to be a Debbie downer. It's a cool result, no doubt incredibly useful for fully optical systems. Probably something really useful here for optical switching at the datacenter infrastructure level.

I was thinking last night how many in some ways these age verification laws might actually have some upside for those of us who were fond of the early internet...

Ultimately what these laws will end up doing is pushing internet traffic towards the "normie web", create a separation between sites which refuse to implement these measures and those who will.

Ultimately for this filters to work authoritarian countries like the UK will need to ban sites like 4chan which do not comply with their age verification demands despite hosting adult content. As it stands until the UK do this the age filtering may as well not exist because kids (and adults) will just go to other sites.

Additionally search and content aggregators will likely come under increased pressure to blacklist these "rogue" sites so slowly both the ability to access non-compliant sites and the ability to find non-compliant sites will diminish.

Like in the old days when cool sites and blogs spread more by word of mouth than social media and search aggregators, we're likely heading back to a world where those who are savvy enough to work around the filtering of authoritarian states will have access to a new kind of "semi-dark web" or a "rogue web".

I almost like that idea. If the internet bifurcates it might actually become a more authentic place for those of us in know. I suppose the only question then is whether authoritarian countries like the UK will ultimately come after private VPN users as well, but I feel like that would be impractically costly to enforce.

I went to a particular sports bar back in the day. They have "all you can eat ribs" plate. The first comes fully treated with sauce and is very, very delicious.

When you order the second plate, it comes without the sauce and it tastes flatter. You're filled at this point and you can't order the third.

Very creative and fun if you ask me. I was prepared for this though, because the people we went together said how it's going to go, exactly.

I think all Robovacs still kind of suck.

We bought a mid-tier Roborock and it's been, meh.

* The "mop" function is pretty much useless. It's very good at creating a thin layer of grime across our entire house. It basically just pushes grime from the high traffic areas of the high into the lower areas. Even with an aggressive setting for "mop cleaning", it just doesn't get clean.

* The vacuum function is okay-ish. It does pretty well at keeping our dog's hair at bay, but it misses a lot of fine dirt and sand.

Where I see the real value of something like this is time-wasting AI agents at monopolies like CVS Pharmacy. These seem designed to be as slow and frustrating as possible & I'm sure the goal is to get you to give up before you can talk to a human. I'd love to see a demo of your agent requesting a callback from a CVS pharmacist. Or trying to talk to Comcast customer service.

What I found interesting from the comments in this thread is not that their services were unlimited or not, and whether it's fair that they added more limits.

Just below me as I type there's a comment saying they're refusing to cancel a subscription (may not be below me any more when I finish typing).

Somewhere lower there's a comment saying they do not show the full price when you subscribe, but add taxes on top of it and leave you to notice the surprise on your credit card statement.

Is there an ethical "AI" service anywhere?

I don't see a world where this won't be abused.

Maybe by the authorities, furthering policies already in place to deal with people who don't toe a certain line of thought.

Probably by people outside the law, who now have a fantastic system to relentlessly attack. A place to source identity information that can be used for almost any part of a criminal enterprise, from buying credit cards to selling new names to carry.

And when security of government systems fail, in a way where damage is irreversible like this case, it is... Rare... To see fair outcomes.

> I don't think you should use LLMs for something you can't master without.

I'm not sure, I frequently use LLMs for well-scoped math-heavy functions (mostly for game development) where I don't neccessarly understand what's going on inside the function, but I know what output I expect given some inputs, so it's easy for me to kind of blackbox test it with unit tests and iterate on the "magic" inside with an LLM.

I guess if I really stopped and focused on math for a year or two I'd be able to code that myself too, but every time I tried to get deeper into math it's either way too complex for me to feel like it's time well spent, and it's also boring. So why bother?
Show HN: App to Help Parents Explain Anything to Kids–and Parenting Questions
by toisanji | 2025-07-29 13:42:04+00:00
I just built an app for children and parents to ask questions to explain to kids and to for parents to ask how to deal with any parenting situation. For example a 4 year old may ask “why does the plate break when it falls?”

Sometimes it can be hard to answer that in a way that a child can understand. The system will go out and scour the web for information the topic, and then rewrite in a kid friendly and safe way. It goes and finds related images, videos, products and reference links. It also gives related words ,quiz, and some games and experiments to try with your child to see if they are really interested in the topic. You can see an example here: https://www.studyturtle.com/ask/lg5areW6-all-about-the-banan...

It has another mode for parents, just ask any parenting question like "how do I get my sons to stop fighting whenever there is a pizza"

This will give you a full research report by going out and crawling the internet and looking for diverse information. This was purposely built to not just choose "the best way" because there is no best way and I wanted to make sure different points of views are foundd with pros and cons. The parenting tips page will find research papers, books, blog articles, related youtube videos, and more information and present it all to you on one page. You can see an example here: https://www.studyturtle.com/ask/PJ24GoWQ-pizza-sibling-fight...

You can ask a parent or kid question here https://www.studyturtle.com/ask/ to test it out, I would love to get your feedback on this.

> More than half of students predicted to succeed in advanced math are denied access to those classes.

> Our research firm evaluates federally funded education programs in K-12 schools. In the early to mid-2000s, these grant-funded program evaluations began requiring measurable objectives and pre- and post-data comparisons. During this period, federal grants aimed at getting more low-income and minority students into advanced STEM courses became a common trend.

> These program evaluation requirements led to a striking discovery. Tens of thousands of high-scoring students in North Carolina were not enrolled in advanced math courses. When staff working on the grant-funded programs (typically school counselors, school improvement teams, and administrators) discovered they already had hundreds of top-scoring, academically successful students in a single middle or high school who were not in advanced math, they usually wanted to enroll them. More often than not, they were told by their math departments that they couldn't enroll these students because students needed a teacher recommendation.

This is incorrect. There are a number of eerors, as others have pointed out, but for me the most central one is not that almost all reals are uncomputable numbers, but that the product of two 64-bit integers is 128 bits, as anyone who has done arbitrary-precision rational math has noticed.

I think it's great to experiment with improving fundamental algorithms, but not to make misleading claims about your results.

The immigration is certainly not unprecedented, we've had significant chinese, polish, and even Italian immigrantion. And they too suffered prosecution.

If the same thing keeps happening and we keep being wrong, I lose faith in the premise. I have no reason to believe the right is faithful on these issues, so I don't care. I'm just going to assume they're making a big deal out of nothing and I'm probably right.

There are videos of civilians storming Hamas warehouses and being shot and Hamas on aid trucks.

If your main source is aid organisations then be aware UNRWA employ members of Hamas and the staff at many others call for the death of Jews on their personal social media.

Shi Yongxin is the person who has made the Shaolin Temple so successful today. Despite being a cultural icon in Chinese traditional and modern novels, the Shaolin Temple has fallen into a dilapidated state before Shi became the head, due to the social unrest in the 20th century. As the Fangzhang(head) of the temple, he managed to revive Shaolin Temple by bringing in investment and developing business such as kungfu performances, medicines, and tourism. I'm not saying that he is a good person. In fact, I found it ironic that his very traits that conflict with Buddhist principles help made Shaolin temple prosperous again.

Personally, I would say that if one is a real PL fanatic, one is more interested in the semantics than the syntax. :)

The problem with the linked docs on the Pony website is not that it doesn't explain the semantics (it does!) but that it seems to be written at a pace appropriate for someone who has no clue what static types even are. [1] Give a concise demonstration of the syntax and the semantics, even if that means that the latter will use terminology that not everyone will understand. Then the full tutorial is there for the details.

That's all understandable. But like I said I did spend 2 weeks working with SQLc, however when I compared it to just writing the query in my code, the developer experience was miles apart.

You could compare it to people writing CSS, JavaScript and Markup in separate files Vs having just one file in React/Svelte etc. which gives the user the option to combine everything into one.

There maybe a lot of drawbacks from the latter approach but it's makes everything a hell easier for people to just get started building.

Nope! Office of national statistics published a CSV for postcode -> constituency name [ https://geoportal.statistics.gov.uk/datasets/6f2f35a9a0b94e7... ], and then the official gov.uk parliament API for a constituency name -> MP lookup [ https://members-api.parliament.uk/index.html ]. So all of the data is the officially available data. I humbly posit that this is a publicly owned bug.

There's a clear difference between "I have used these tools, tested their limits, and have opinions" and "I am consuming media narratives about why AI is bad"

AI presently has a far lower footprint on the globe than the meat industry -- The US Beef industry alone far outpaces the impact of AI.

As far as "work pillaging" - There is cognitive dissonance in supporting the freedom of information/cultural progress and simultaneously desiring to restrict a transformative use (as it has been deemed by multiple US judges) of that information.

We don't see eye to eye, and I think that's ok. We can re-evaluate our predictions in a year!

==why did they usually do it==

I'm not entirely sure, maybe they did it to give people a narrative to distribute? I just know what they are doing now, which is forced starvation and violence without warning. The exact thing people warned about before the conflict started.

Why would you forcibly starve a population of civilians if your goal wasn't to eliminate them? Why have they blocked outside journalists from entering Gaza for over 600 days if they weren't trying to hide their actions? Starving civilians in an area where you control the airspace and coastline isn't a "spiral of violence," it is a war crime.

Posting at the top to point out that if you saw the image of a starving child recently, you’re looking at images of a child with a genetic disorder and you should reconsider which media you consume.

You can also find more images of Mohammed al-Mutawaq, an 18-month-old with cerebral palsy, with his healthier sibling - which was cropped by the media to exaggerate claims of starvation.

It means that the language and runtime both agree not to look at your dead-end state, so no-one can say it's their fault ;)

For example I can define a notsemaphore actor that calls a callback once an internal count reaches 0, and then I can forget to decrement it and so it will never reach 0. But technically this didn't involve synchronization so there isn't a stack trace to tell me why is my program stuck and somehow this is better.

I have to disagree with the "Christian Nationalist" characterization.

https://www.politics.co.uk/news/2025/07/29/nigel-farage-taki...

>"Nigel Farage ‘on the side of predators’ with Online Safety Act criticism, says Labour"

Is the UK's Labour Party now Christian Nationalist?

The end goal here is digital ID and censorship. Compare this to the perennial efforts for encryption backdoors. If there is a characterization that accurately encompasses this, it is the illiberal, statist, authoritarian impulse. Sure, they used a sex-panic to advance their agenda. However, this is merely symptomatic of the larger illiberal trend towards authoritarianism and the expansion of the state.

Both China and Russia have claimed parts of other countries using the tactic of moving in their people to then use that as an excuse to annex or overtake those parts.

Crimea for Russia as an example, but this is also true for other former Soviet states.

With China it's been Bhutan, India, Vietnam, Philippines, Malaysia, Brunei, Indonesia and Japan. In addition to their claims over Taiwan or their excuse to (culturally) genocide the Uighur in China).

That is ignoring Africa as a whole, where conflicts are far more common. To name a recent example, over 50,000 Nigerian Christians have been killed by Islamists in the past 16 years. The world is far more bloody than most people seem to realize. The world peace has only been a peace in a relative sense.

Okay but why isn't it possible? You can't just say thing and then pretend they're true.

You've had like 3 comments now to explain why you think it isn't possible and you've decided not to, presumably because you can't.

I think it's possible. We've done it before. I've already explained the benefits.

Okay, so what now? I have an argument, you don't. Feel free to provide one, or don't, I don't really care because I'm starting to think you're not acting in good faith.

There is a parker-style 0.5mm point refill from jetstream (Uniball Jetstream SXR-600) that I used in my Rotring 600. Thin point and dries instantly, very nice for taking quick notes. However for the last year I have switched to a Jetstream Edge 0,28 mm point pen which unfortunately does not fit the Rotring 600.

Why don't we just require kids to price they're an adult before accessing the Internet then? The issue with these laws isn't the goal, but the implementation is fatally flawed. Do you think websites like Worldstar are going to implement age verification? Of course not, no foreign site will. Then the next step for a law like this must be censuring all of those sites across the country.

Who defines what should be censored? The law certainly doesn't; it's purposefully vague to give the most latitude possible to the implementers. There's already been cases with the new UK law where peaceful arrests were censored by the law due to "violence."

VPNs exist, proxy websites are easy to setup, and frankly parents need to take some ownership.

Two alternative laws that'd have been much better: a) Require ISPs to provide a child friendly Internet gateway that would blacklist large weather if the Internet without a login. And b) legally require websites to accurately describe the content on their page and it's age appropriateness in headers sent back to the user, so the ISP or end device can decide whether to age gate a website.

These are much better solutions, the burden on websites isn't so onerous (many small sites have already had to shutdown due to the burden of the UK law). Implementation is distributed, preventing a single state actor from having full control of a censorship machine. Parents are empowered to decide what content is okay for their children. And you don't have to upload your fucking ID to use the Internet.

People who support this crap need to stop believing politicians every time they say "think of the children!"

On a more serious note, I'm sure most of the people can't fathom or even think about the resources they are consuming when using AI tools. This things doesn't use energy, they consume it like how a black hole sucks light.

Take Reddit as an example: Reddit became big after Digg fucked up their mainpage and has replaced most hobby forums and discussions on the internet. A competitor to it would have to implement a lot of compliance stuff like age verification and that would be very expensive, making it harder for a competitor to be bootstrapped. That's why Reddit has an incentive to support such regulation, even if it costs them a lot. Once implemented, competition becomes harder and harder.

I've only seen two episodes of The Expanse after reading the books, but I will 100% upvote the book series. It's one of the best sci-fi series I've read in years.

I kind of want to give the series another go, I just rarely watch TV. I'm currently 5 episodes in of an 18 episode series over 3 months lol.

Side-tracking a bit further, "Murderbot" is also a fun sci-fi series although much lighter than The Expanse. And now I'm reading "Bobiverse", just ~150 pages in but enjoying it as well.

I wouldn't call myself a vaccine skeptic, and I don't have a problem with anything else you said, but "feel entitled to disregard medical science progress" puts my back up. We are in fact all entitled to that.

I think a not insignificant part of the skepticism problem stems from well meaning authoritarians who believe they have the right to shoot everything that has a pop sci press release behind it into everyone else's bodies.

It's like the opposite of the naturalist fallacy: if it's man made and has a sciency name, let's assume it has no glaring flaws until we get the class action lawsuit recruitment commercials a decade later telling us we might be entitled to 5 dollars compensation if we're on our deathbeds because of some horrible complication.

Even better if your political tribe has tied its identity to the thing.
