> if you need to be working very hard to give your kids a stimulating, healthy, childhood.

They don't work hard, they enjoy themselves.

They also have hobbies and my friend is always working on some hobby/home project. His wife is very social and is always planning something and he has no issues following along as he likes going out and doing things. They take the kids because they enjoy being with them and the kids also enjoy going out too.

The big issue today is the fact that parents are distracted by phones so their kids follow that example. It used to be everyone sat around, watching TV or talking to a friend on the phone. Those were limited activities as eventually you got tired of talking or nothing good on the few channels of TV so you found other things to do. Now its phones constantly pumping out attention stealing content 24/7. It's a prison.

i am totally an advocate of the 15 minute city, but the strike thing is a genuine problem, it's total blackmail. yes, they are asking for better working conditions, but then you look into the details and it's because early retirement age has been raised from 56 to 58 and days off have been reduced from 28 to 26. that sort of thing cannot be indulged. i'm getting to an age where i know seniors in my european side of the family that have been retired longer than they have worked, but insist they deserve their yearly vacation. that social contract meme is real.

>The objective of providing free childcare to anyone that wants it is to enable people to avail themselves of free childcare.

The objective of excluding the parent from that has been made pretty clear at this point, which is a deliberate choice to destroy the family unit.

>Value is also determined by the fact that stay-at-home mums are willing to look after their own kids for free, and childcare professionals are not.

The free market value of taking care of 1 child under some arbitrary standard of care is not meaningfully impacted by the fact an arbitrary person might do it for free, anymore than the fact I might be willing to search for gold for free reduces the value of gold. It will have some effect in aggregate, but that effect would impact the whole market so is meaningless in the context of differentiating a universal payment.

>Makes it easier for parents to decide to work if they want to, but I thought ancaps liked that sort of thing...

It indeed does make it easier to decide to work if you're now getting taxed to cover $12K per child of every child in the whole state going to daycare, and you get none of that for your own kid unless you put them into daycare yourself because magically your own childcare doesn't count.

>The absolute best thing we could do for children is to ensure that those of them who have low-earning parents stay at home on their own with no daycare and no education?

I said from the beginning I wanted a waiver. i.e. reduction of taxes. I would put taxes at 0% and free up lots of jobs and returned tax money to low-earning families so they could afford more for their children, which I think is the best thing possible for them. With the added effect they can spend that money freely rather than having a state lord over them what one public school they can spend it on or lording over them with their own stolen money what childcare provider they can use.

The reason why I would argue for equal subsidies if they're provided is I believe either no tax, or equal subsidies is the most liberty minded solution. The solution where the state forcibly taxes and then lords the money over you depending on whom provides the childcare is the lowest-liberty solution of all of them. That is why I'm a temporary ally of the policy alternative I reference.

Thank you! This has been an exciting project to work on!

For the industrial robot (in the video on the main readme page) I intentionally gave Claude no context beforehand. All of the inferences that you see there are based on information that it got through the MCP tools that let it analyze the ROS topics and services on the robot.

In fact, I had a starting prompt to ignore all context from previous conversations because this looked to be like an example of emergent behavior and I wanted to confirm that it was not picking things from my earlier conversations!

I love my personal car bubble as much or more than most people (though maybe not as much as you), but at some point we have to get over ourselves. We're all so spoiled. Why the hell do we deserve to all have our own giant speed machines careening through cities where people (including us drivers!) are trying to live? It doesn't make any sense and it's a shame that we've let it go so far, especially in the US.

It should be discouraged (financially, logistically, socially) to drive in dense urban places. Obviously, in order to achieve that, these urban places need to have alternative means of transportation.

> [...] python notable for their giant reliance on libs.

I object. You can get a full-blown web app rolling with Django alone. Here's it's list of external dependencies, including transitive: asgiref, sqlparse, tzdata. (I guess you can also count jQuery, if you're using the _builtin_ admin interface.)

The standard library is slowly swallowing the most important libraries & tools in the ecosystem, such as json or venv. What was once a giant yield-hack to get green threads / async, is now a part of the language. The language itself is conservative in what new features it accepts, 20yro Python code still reads like Python.

Sure, I've worked on a Django codebase with 130 transitive dependencies. But it's 7yro and powers an entire business. A "hello world" app in Express has 150, for Vue it's 550.

Regardless of someone's stand on the topic of remote vs in-office, I find it staggering that _anyone_ could believe that either one of them is the one-true-way. There's downsides to both and either decision is likely to make at least some of the participants unhappy.

I'm firmly on the WFH end of things; I much less productive in an office. But I know other people that are better in the office with the ability to talk things over with co-workers in person. And the fact that I'm not there makes it harder for them (and easier for me; tradeoffs)

So a tax financed site telling how it's great to have more tax and regulations. Not surprising. Find it very weird to have government trying to gerrymander things just as we are on the cusp of EV transition and autonomy. Go take a ride in a Tesla with FSD, the future is here, let it come in, get out of the way. In a few years with autonomous vehicles the need for vehicle ownership wild radically decrease and with that a huge need for parking space will simply vanish.

What I suggest instead: make electricity super cheap use all the ways possible create space for charger system but let brands compete( don't over regulate) Allow autonomous system to operate, be a trailblazer in the field.

One factor here is the perception of safety. To choose public transit over a car, you have to feel safe walking to/from the station and you have to feel safe riding the train. This is especially true if you are at a physical disadvantage because of gender, disability, age, whatever. Because it's a perception thing, this is not just about statistics. A dirty, chaotic subway station just feels threatening to passengers.

I've ridden public transit in a bunch of cities, and this makes a huge difference to how welcoming the experience is. Hong Kong is #1 for me. The trains and stations are clean enough to eat off of - probably cleaner than my car. On/off boarding is fast and orderly even during peak travelling hours. This is not a universal, and there are definitely cities where I would hesitate to take public transit if I had some other choice - which is the root of the problem when you're trying to convince a population to fund and use such a system instead of bringing their cars.

it has been quite impressive so far. It makes very less number of mistakes.

Cons: Context size if less so compaction happens frequently. Interesting bit is that the compaction doesn't seem to affect it as much as the Claude models. So I don't have to continuously look at the context size. Also it doesn't seem to lose the coherence even when nearing like 1% of the context.

Would you give heroin to your kids? No? Then why give them social media?

Both are highly addictive. Both rewire the brain. Both damage the ability to form healthy relationships.

We need to stop pretending this is harmless. The long-term effects on attention, empathy, and identity are becoming clearer and more alarming.

It’s time to treat digital exposure with the same seriousness we treat chemical exposure. In so doing we need to ask an even more uncomfortable question: if it's so bad for children then how can it be good for us?

Mandatory access controls, fine-grained capabilities, temporary capability grants, risk scoring, progressive disclosure, high-level intents that encapsulate permissions, and most importantly, an audit system.

We have the hindsight of developing highly distributed low-trust systems. We can do better than `curl -fsSL https://remote_install_script/ | sudo sh`.

Trump took office in January, so I'm guessing this has nothing to do with tariffs like people are implying? I didn't read the article (paywall), but if that is the case why was this misreported? couldn't he have just blamed biden or something? Either way, that sounds like a big number, is it interest rates that are causing this?

> Cool, get big enough, become friends with the right people and you can squat an entire name on the internet. What, you're the Nepalese Party for Marxists, you've existed for 70 years and you want to buy npm.np ?

I think you and I have drastically different ideas about how dramatic a response is warranted by the scenario of needing to buy a domain with a different three letters or maybe even four or more letters before the TLD.

> Dare I remind you that the whole left-pad situation was because Kik, the company, stole (with NPM's assistance because they were big enough and friends with the right people) the kik package ?

...and then the package was entirely removed, which would have been preventable by sane policies around making removal just not allow new dependencies to use it. You're also conflating a resource that's ostensibly free and perpetual for people to claim with one that's only rented for fixed periods of time for money.

I think I can follow this artikel, but am unsure. Are these mortgages backed by the underlying real estate?

“ Among the newly delinquent multifamily mortgages was the $62 million mortgage on Park West Village in Manhattan. The 4.65% fixed-rate mortgage on the 850-unit property, built in 1950 and renovated in 2014, was originated in August 2022. In August 2025, it became 30 days delinquent.”

62 million / 850 = 80k per unit. Seems easy to cover?

I'll add that cities in the U.S. west, which did most of their growing after cars were invented, just don't have what it takes. At this point they're trying to find a way to squeeze bike lanes into roads that were never designed for them. They're trying to pay for public transit between metro centers that are 50 miles apart and separated by gulfs of nothingness. A hub system is much harder to support when the center is so far from the edges.

I accidentally started using Pinterest to organize infographics on my phone, which led to resurfacing material on a daily basis.

The process of organization with the app on my phone is itself mindless enough that I can focus on the meaning of what I'm looking at.

That's the friction point in a lot of these PKM solutions - the process of using them is set up for Big Important Tasks. The process of using the interface interferes with the flow of thought.

> It's not pro- public transit and better urban planning that bothers me. It's the anti-car "lobby".

The absolute worst are the "war on cars" people. Not the people who are "anti-car", because while there are some, there's really not that much, so you don't hear those people. No, the people who argue that spending a dime on anything that's not for cars is a "war on cars" and will vociferously reject any investment in public transit. And those tend to be the people who run transportation departments!

But you tend to lose your most capable employees when you create a bad/undesirable/etc work environment. I think people are attributing malice where the intent is merely...not incompetence, but it's what everybody else is doing. People forget that business goes through fashionable phases just like everything else. Microsoft fell victim to idiotic trends (stack-ranking, AI, etc) just like everybody else has.

I don't understand, that recent article is a fairly balanced take on what the title literally asks: What if? It examines what if the hype is true, or what if it is partially true. That seems like a good article. You might have a point if the article was, "The hype is true: examining how the world will now change" or something.

I'm unconvinced with this article. Whilst obviously a smart guy, I don't think Lemire really works on the same problems most of us do. Looking at his posts and publications it's generally high peformance work on problems that are small in scope. I suspect most people actually work on far bigger projects than he does! Neither do I see from that arctile that he's actually used a modern debugger to its full potential. I rarely step through code in slow motion, but sometimes it's great to see program state. If there are thousands of files in a project I don't know well, I can put breakpoints to test hypotheses about my understanding.

I find this sort of claim really common (the commenter you responded to).

Skin color is unfortunately correlated to socioeconomic outcomes in the United States. Once poverty is controlled for, at least in my analysis, most of this difference is ameliorated (though mild correlation persists).

Most people in this vein, at least in my experience, will describe after a long conversation that they think there can only be two sources of correlation - genetic ("nature", which I disagree is a primary cause of socioeconomic outcomes) and a weird subset of nurture that fails to take into account intergenerational impact (history), instead focusing solely on state (assertion of Markovian process to life).

In my view, nuture breaks out into those components -- history defines the resources you have access to in your broader community, and state defines your immediate challenges. It's hard to get resources to change your life if you have a bad state, but it is possible. Americans love an underdog story and the bad-state good-history fits it well. Bad-history leads to a lot of additional issues -- systemic type issues. Americans have seen this in both hostile urban planning to a full community and to hostile resource reallocation to rural areas (towns shutting down with no way to recover) in favor of suburbia. From my studies, I think Strongtown lands the description of the issues (Youtube channel).

I'm not epistemically arrogant enough to assume I am 100% right here -- much of this is from 20 years of research experience but there is always more to understand at a population level and how that relates to the individual level.

I am epistemically arrogant enough to require people to hold to their ideals -- if someone wants to ensure equality of opportunity, that has to both be for the state (Little Jimmy and Jane come from a poor family) as well as history (and none of Little Jane's community has been to college and nor do they understand the college application or financial assistance process; further, most are unbanked and most of the male population can't get gainful employment due prison sentences connected to overpolicing and/or desperation behaviors [a catch-22 for communities wanting to build a brighter future while also exercising punitive justice]).

For me it's more about "feeling" badly written code, as if it stinks and is unpleasant to look at, and conversely enjoying nicely written one, and seeing its elegance and beauty.

Especially when I have to familiarize with code written by someone else, I usually start by "cleaning" it - small refactorings such as splitting overlong functions and simplifying expressions, that are trivial to prove as correct even without a deep knowledge of the code purpose.

Only when the code looks sufficiently clean and familiar, I start adding the requested new features

People don’t pick their mode of transportation based on space efficiency.

They pick their mode of transportation based on their needs and priorities. Taking the subway works when there’s a stop near your home, a stop near your destination, and you have all of the time necessary to wait for it. If these conditions aren’t met then you need additional transport to and from one or both ends of the subway journey.

There’s also the matter of weather, which is less obvious to people who don’t live in locations that see extreme weather or deep snow. Safety and cleanliness is another issue depending on the location. There are cities where I’m just not going to take my kids on the subway if I can avoid it.

People who hold up numeric metrics like number of people transported per unit area don’t understand why people prefer to hop in their car and go to their destination rather than spend potentially far more time navigating a crowded subway system.

> Firstly, there's only one sentient primate race: Homo Sapiens.

Nope, species, not race - or arguable sub-species.

As your link says race is a social construct, so it is whatever society says it means. It means different things in different societies. This is something I experience personally so I am very aware of it: https://pietersz.co.uk/2023/08/racism-culture-different

> However, when genetic variation is compared both between and within those groups, we see more variation within those once isolated groups than we do between those groups

Which is why genetic similarity does not work well as a way defining race, and why the concept of race has no biological basis. This is covered by the wikipedia link in my previous comment too.

> What's more, even within such groups genetic variation is only around 0.5-1.5%.

Yes, but that is just normal for a species. We share a lot of DNA (98%?) with chimpanzees and something like 70% with fish! its not really meaningful. However, its not the main argument, because the variation within vs (lack of) between groups is really the killer argument.

This is generally true, but there are some additional aspects.

1. With PostgreSQL heap, you need to access the heap page itself. And it's not for free. It goes all through the buffer manager and other related components.

2. In OrioleDB, we have a lightweight protocol to read from pages. In-memory pages are connected using direct links (https://www.orioledb.com/docs/architecture/overview#dual-poi...), and pages are read lock-less (https://www.orioledb.com/docs/architecture/overview#page-str...). Additionally, tree navigation for simple data types skips both copying and tuple deforming (https://www.orioledb.com/blog/orioledb-fastpath-search).

According to all of the above, I believe OrioleDB still wins in the case of secondary key lookup. I think this is indirectly confirmed by the results of the TPC-C benchmark, which contains quite a lot of log of secondary key lookups. However, this subject is worth dedicated benchmarking in the future.
