Discriminatory pricing feels nasty when you're get the short end of the stick but any pricing scheme will have bias. Having a high wage earner pay the same fare for a service as a low wage earner gives a much better deal to the wealthier person. (In Finland traffic tickets are calculated as a percentage of your income)
In many countries you will pay a surcharge if merchants think that you are wealthier since it implies a greater ability to pay. (Bulk discounts are not universal)
The point where a flexible price structure becomes a problem is where price gauging is being practiced to take advantage of people in a bind.
That assumes everyone picks their job as a rational economic actor. This is clearly not the case. Even if it were, if you believe you have a decent change then you might as well give it one shot, and if it doesn't work then you can fall back on something else while you're young.

Note that this is the same rational for starting a startup. Would you argue that all successful startup founders are the best of a bad lot?
What do authorities do for international cases?

Don't get me wrong, I'm all for pursuing any person who behaves as in the article to the greatest extent possible, but you they have to get IP, dig up the person, contact authorities in that country and hope they do something?

That's a lot of paperwork for maybe something _might_ be done and no one died and no large amount of money went missing (so to speak).

Maybe it's not so much they don't care (most people would care about this no?) and more they are limited in resources (and perhaps motivation) and it is difficult to get results.
What if they share the link on social? All the new traffic would seem to be non-unique.

I think that's the most succinct way to put it: Give children stake in your interests.

It doesn't even have to be direct. If I'm working on a lesson (I teach technology), I can ask the kid to come up with some ideas, help clean the room, decide on what to have for lunch, help me grade assignments, etc...

At home it's the same. Help clean, ask if they can help me find a mistake I made, ask about food, ask them to comb my hair (funny, but kids 3-10 love doing this for some reason), ask them to put some music on for us, etc...

Of course it doesn't always stick and the kid wants some other attention, but when it _does_ stick I find it to be as beneficial as the time lost.

> They’re all children. And like every case of abuse, a child is never at fault.

This is accurate, first and foremost before what I say could be interpreted as shifting the blame from these perverts. But one thing not mentioned in this article is why an 11 year old would be on the internet at all. I think we need to have a serious think about whether it makes sense to expose a child to everything to world has to offer, unguided, before they're much older than 11.

There was a lot of optimism about the internet, or more specifically the web I guess, as it developed. But realistically it's not the utopian vision many expected it to become, large parts of it are a cess pool.

Back when I was younger the idea that it would aid in education, and make it easy for children to research any topic. Is that truly the case? I'd argue not, misinformation is rife, could any child really be expected to critically examine this stuff unguided? I think we were better with something like encarta to be completely honest.

Social media is an abomination, I'm not convinced many adults have the faculties required to use it in a non destructive way. How many of us have parents that seem to be completely radicalised by one Facebook group or another? We know that because they won't shut up about it, so what's it doing to a bunch of kids that don't share what they're reading with their parents? God knows.

This is all before we admit that children can be really quite cruel, which gets magnified by them not actually seeing the result of their words/actions. Putting a screen in-between the bullying is a sure fire way to make it much worse. Couple that with the isolation that's felt by this fake 'social connection' and its a recipe for disaster.

I really worry about the future if our education systems can't be retooled to teach children critical thinking, and if we don't start to change the way we look at the internet to realise its way more dangerous than we expected it to be.
> The opposite -- a presumption that people always vote in their own best interests -- is equally condescending because it's an expression that nobody can really believe.

It's hard to believe that every position of a candidate you vote for is in your interests because that's basically never the case.

Suppose I support the elimination of most federal programs and taxation (let the states do it) but I think that a federal carbon tax which is paid out as a dividend to the citizens is a great idea, because it's a national/global issue and pricing externalities is the legitimate purview of government. Who shall I vote for? I have never seen a single candidate proposing to do both of those things.

In a sense the only way for me not to vote against my interests is to stay home. At the same time, there are two candidates on the ballot that are very much not the same as one another. So it's not so much a matter of "voting against your own interests" as choosing which of your interests outweigh the others.

But assuming that anybody who makes a different choice than you is a fool is very condescending.
Yep. That’s about it. That feeling of not being able to do something, but not being able to do nothing. I keep imagining that when they grow up and leave home I’ll have an almighty outburst of productivity as I get cracking on all the thoughts and ideas I’ve had that haven’t made it far up the priority list.

Isn’t price discrimination embedded in nearly every transaction we engage in, though?

What is the difference between price discrimination between classes of individuals (to your point, business vs leisure travellers), and individuals themselves?

Nearly every pricing guide on this site recommends offering an ‘invoiced’ pricing plan for enterprises for substantially more than the same service on credit card billing. Price discrimination at its finest and, I would argue, a good thing for suppliers to extra more of the benefit they are providing to consumers.

I made it clear with my wife that I would need to have some time for my activities before we had kids. Luckily she has some friends that believe the same because she has no hobbies. So we take turns each month giving each other time away from the kids. So she might go out with her girlfriends and I might go golf or kayak.

Also, I don't subscribe to the notion that a parent needs to be playing with their kid every waking minute. My wife is more toward the opposite but getting more flexible. My son plays with Legos and other building toys by himself and I like that. I did the same when I was young. You have two kids so let them play with each other and you and your SO should dedicate more time as partners together. Get your date nights in.

Your kids are getting old enough that they should be playing with each other all day long soon and that will open up your time. Mine are younger than yours so I have a few more years but I hear having multiple is a game-changer for parents.

The other thing I would suggest is to just take your kids with you everywhere you can. I got a hiking backpack and I take him to music festivals, he's flown overseas and traveled around Europe, National Parks, etc. He doesn't make a peep in the hiking backpack and loves being able to see different things outdoors. I highly recommend!

As far as doing a side project, maybe do the planning/strategy for it while hanging out with them but when your kids are playing with each other. I can't code very well with kids around but I can still ideate.
The idea is that such end-to-end techniques can be used to tackle problems for which we don't have background knowledge. For example, (according to DeepMind's latest paper on MuZero) real-world robotics tasks etc. Atari games are a good use-case for this because they dont' have very clearly defined rules like board games have, so a model basically has to first learn to play the game before it can learn to play it well.

You can perhaps design a game that is difficult to solve by AI (though I wouldn't bet on it). The question with AI is usually not what it can't do but what it _can_ do. If a certain system fails at your task but performs well in a range of other tasks that are considered useful and challenging, then it's worth consideration. Especially so if there is no system that can perform well on that one task.

Just because pedophiles are common on social media doesn't mean they're particularly lucrative as a demographic . It's not as if they can legally form pro-pedo groups and chat and share child porn and create a social graph around their interests that would be of any value to advertisers.

There's a strange anecdotal contradiction with the research. Although much research says otherwise I'm finding that anecdotally people disagree with my statement and they actually end up have multiple children indicating that the first one was an enjoyable experience.

I think what's going on is that those research studies are picking up on unbiased measures of happiness.

In general if you ask people if children make their lives happier, they answer yes. However if you ask the same people about there overall happiness on a 1-5 scale people with children score lower then people without.

This makes sense from a biological perspective. Having an extra person to take care of; who only takes advantage of your hard earned resources without contributing does not give you any intrinsic form of happiness in any context unless this extra person is your child. Your body produces chemicals to counteract the unhappiness to satisfy your biological imperative but the main stressors are still their and can be measured in a survey that asks you questions about your happiness without the context of children.

It's hard to say if it actually is better to have kids. Is it like falling in love? Are we better off with the ability to fall in love?

As of this writing, my initial post has negative three votes which indicates general disagreement. Obviously, I don't have kids so I can only observe the phenomenon from an impartial standpoint.
I'm waiting for the moral grandstanders to take to social media and try to publicly shame companies for refusing to hire their trained ex-cons
I've noticed significantly higher prices starting about ~6 months back to the point that is has actually driven me to go fewer places. It being rainy season in San Francisco has also pushed prices up to $40 or more for a ~3 mile drive some evenings. I actually canceled plans when an Uber Pool was $36 and Lyft even more than that just a few days ago. It's just not worth paying $70+ round trip to grab a drink. I'm willing to bet drivers will see some loss in revenue as a result of higher prices but that's just my opinion.
These pictures are funny because some of the stereotypes are true. For example, those lumberjack shirts from Marks Work Warehouse are total chick magnets here in Ontario.

> prevent those guys from becoming predators.

You think this hasn't been tried? These guys are not like you or me, they are severely lacking in empathy. They feel no aversion whatsoever to engaging in predatory behavior on fellow humans, including kids, as a matter of basic temperament. You can prevent them from becoming predators only by providing clear consequences for such behavior, and an appealing alternative for them to choose instead. (The latter is why smart people don't tend to become predators of this sort - they have other ambitions, whatever those might be.)
I would assume that, at the very least, every large social media platform that allows image uploads is checking them against a law enforcement database of CP hashes. If not, they should be.

Ah gotcha. Yeah there is definitely a lot of pastel palettes on there. I guess that's what I lean towards. I'll try to add more, non pastel palettes soon :)
Imagine you're the sort of guy to slip into the DMs of a random hot of-age woman and she actually replies and engages you in conversation.

"Grooming" is nothing more than establishing a relationship and rapport with the aim being naked pics and ultimately in-person sex. The difference is the target here is a child, and thus more easily manipulated.

Just ask any of your attractive of-age female friends how many times they get harassed on social media by random guys they don't know if they have their DMs open. Which they probably don't.

My point is these people are acting like many horny guys on the internet. The difference is their targets are kids, but that doesn't make them psychopaths, it makes them pedophiles.
I'm in the same situation kid-wise but I don't feel like I have no life. I do manage to get some time to myself to exercise and grab coffee with friends now and then.

The key to this is working remotely. Two major advantages that apply here:

1. Not wasting precious time on commuting (even 1 hour makes a huge difference)

2. Being way more flexible so I can run errands and house chores mid-day if I'm feeling unproductive and use the time I earned to catch up on work later.

If working for a distributed company is an option for you - I can highly recommend. If not - from what I see around me it gets way easier and more fun when your youngest is ~3 y/o.
>already carrying the fixed costs of owning a depreciating vehicle

Except depreciation and other costs are pretty heavily a function of miles rather than time. (Especially outside of the snow belt where the number of winters plays a big role in salt damage.)

>They also don't have to front the capital cost of a medallion.

That's true but how many places is that a big factor?

We can argue the details and you're right that it's hard to compare dynamic pricing to long-term negotiated fixed pricing.

But I'm not really making a case for exactly where pricing/costs will end up assuming sustainable ride-share businesses. I'm just saying that taxi fares in most markets are probably a reasonable benchmark whether or not ride-share on average settles a bit higher or a bit lower.
Transactional Data Structure Libraries
I was reading a story a while ago (I don't recall enough about it to even search to provide a link) that talked to some pedophiles. Specifically, people who had the urge to interact sexually with young people. It talked about how some of them knew this was a bad urge and acted to counter it. One of the ways they did that was to get hold of fictional child pornography (stories, drawings, animations, etc). This allowed them to feed their urge without hurting anyone.

The idea behind the disucssion/story was that pedophilia (the desire) is a condition (like any other we treat; alcoholism, depression, etc). Treating it like that, looking for ways with the urge to avoid hurting people, was a reasonable approach. It was argued that making such fictional items illegal hurt, rather than helped, children; because it took away non-harmful outlets for the desires.

It gets better - My kids range from 14 to 9.The 14 year old is hanging out with friends and making jewelry. The 12 year old is sitting in my bedroom, reading. The 9 year old is playing games. I'm coding on personal projects, and my wife is in the basement making blankets. We have an entire day of just all doing whatever we want. Weekdays are busier with school and work, but you the point is that you do get your time back, once the kids are old enough to have some independence and interests of their own.

I'd recommend just enjoying being a parent while they are young. They need you at this age. Play with them, read to them, and all that. Write down ideas you'd like to pursue in a couple years when your free time returns. And you can be confident that it will return.
This may be a US only issue but isn't the below section illegal discrimination against older workers? The sentence about being at an advantage with "pre-trained resources" is also a fairly disgusting view of what are ultimately people imo.

2. Attract more young blood
Modern and innovative technology attracts young and new
workers as even education focuses on these specific needs
of the industry. Businesses are at an advantage when the
resources are pre-trained rather than investing time and
energy in training the existing resources. Fresh minds
also mean fresh ideas. In a business world demanding
constant innovation and rapid growth, there couldn’t be a
better time for both businesses and youngsters to grow
together.

I've seen this viewpoint taken over the entire industry with every company I've worked start to refuse to hire people below senior level and removing any time or money allotted for training or learning. Everyone's expected to come in knowing their tech stack already and if the industry moves you're expected to learn on your own time.

Knowing the max someone was willing to pay could help an actor set their prices optimally where there is no competition. Where there is competition, setting price to the max someone is willing to pay could drop overall profits since a competitor would happily undercut. So it does not change the rules of the game.

Companies already price by predicting what people are willing to pay, by theory and experimentation. I wouldn't expect them having perfect information change much other than quicker convergence to the prices they would set anyway.

Yesterday I fell in the Collatz trap (https://news.ycombinator.com/item?id=21780068). So after a few hours my 7y old son asked what I was doing (what was I doing?!). Explained him how it works and then we did Collatz "by hand" for almost an hour. These sorta random triggered experiences are the best.

Good writeup. As a tech nerd, it's easy to get carried away with fancy things (breeders! MSR's! pyroprocessing!), but what nuclear really needs to succeed is driving down costs and improving public acceptance.

> Many advanced reactor companies talk about using high-assay low-enriched uranium (20% enriched rather than 5%), which is economic bonkers. But enrichment and uranium are dirt cheap at the moment due to overcapacity from the Japanese and German nuclear shutdowns. This won't last though, and the HALEU reactors will very likely be too expensive to operate if they do actually get built.

Hmm, sure, enrichment cost doesn't increase linearly as a function of enrichment, but it shouldn't be prohibitive either, particularly as fuel cost is such as small part of the total?

Of course, to get correspondingly higher burnup you probably need a new fuel design, and probably also burnable poisons, which will increase costs.

> Put simply, this means we must build reactors that have only a tiny number of valves, cables, motors, etc. that are needed to safely shut down and cool the reactor.

Isn't this what Nuscale is basically proposing (in addition to riding the SMR bandwagon, which may or may not work out)? Their design is cooled by convection, and can be indefinitely passively cooled after shutdown.

> In 1957, Walter Zinn (director of Argonne National Lab) suggested that liquid metal cooled (low pressure) natural uranium fueled (like a CANDU) reactors were most likely to succeed economically.

Interesting, got a reference? I couldn't find anything via some quick searching.

Though 1957 was also before centrifuges drove down enrichment cost, so the benefit from low enrichment isn't as great today as it was back then.
