No, these are not necessarily examples of market failure. I'd suggest reading up on the concept. A large and long lived discrepancy between the price of something and its cost of production might be an example of market failure, perhaps due to a monopoly. It might also be due to government failure (excessive regulation, subsidies, tax policies, etc.). A temporary discrepancy is not market failure at all, it's how markets work.

In the case of child care it is not even clear this situation exists, most of the reasons you listed earlier were reasons why it is expensive to supply child care and not evidence of excess profits.
I love this 3-day graph the best:

https://forecast.weather.gov/MapClick.php?lat=<your latitude goes here>&lon=-<your longitude goes here>&unit=0&lg=english&FcstType=graphical is my favorite.

Just substitute your XX.XXXX latitude and your YY.YYYY longitude (negative from 0 if you're in the US) for the <> and their contents as variables.

There's also a tabular form of this. Very dense in terms of hourly forecasts. I tend to plug in various lat/long changes to figure out when a storm is going to blow into the kid's sporting event clear across town. Each degree of latitude or longitude is 68.3 miles, so you can usually just adjust the URL to get a pinpoint forecast...which is useful in metro areas where you might be traveling 40-45 miles to an event.
CPython already has a lower latency GC than PyPy, gc.disable() already works, and allowed manual memory management when needed.

Reference counting allows you (if needed) to keep references to memory in your python code, and free them in the right spots.

This is PyPy becoming useful for a lot more production use cases. From web APIs that have a latency SLA, to audio, games. In many cases peak performance is not important, it's the minimum performance.
Ask HN: What is the draw of React?
I've been building database-driven web applications since the days of classic ASP and was an early Rails adopter. While I believe in using the right tool for the job, I've always seen myself as someone open to radical change. That's why I am so uncomfortable admitting that after several years of trying to understand why people voluntarily use React, I still don't get it.

I've concluded that either I'm officially in my dinosaur years or the current generation of web developers are experiencing a collective hallucination.

Sam Stephenson made a really good point in this excellent video introducing Turbolinks 5:

https://www.youtube.com/watch?v=SWEts0rlezA&t=3m22s

Unless you're Facebook or Google, you likely don't have the same problems they do. Just because Facebook needs to reimagine the Button doesn't mean that you should do that on your MVP. Lest you accuse me of being hyperbolic, there are over a million instances of "button.jsx" on GitHub:

https://github.com/search?q=button.jsx&type=Code

Googling for answers to explain why people use React:

- you can build "reusable" components

- the virtual DOM is easier to work with and faster to update

- you can finally blend all of your HTML, CSS and view logic into one file using a weird JS/HTML hybrid that has all sorts of quirks

- you no longer have to write CSS... write it as a JS object, it'll be awesome

- easy to learn in just a few hours

I don't have any of these problems, and no project I've ever worked on would have benefitted from someone announcing that instead of getting a proof of concept working they would first focus on reimplementing the concept of form elements. As for it being easy to learn... ¯\_(ツ)_/¯

I genuinely want to be convinced or at least understand why this library is so popular. Give me your best examples of how React made something easier, better, faster. What justified the pain of throwing out 20+ years of accumulated best practices?
Thanks! Doesn't really stand for anything just a domain I liked.
> Economically we are far better off with children in care and parents in the work force but this may not pay off in the long term if future generations fail to perform in life.

Who is "we" in this statement? The parents? Society? I think whether it makes sense varies from family to family. When my daughter was born, my wife and I did the math and it made zero sense for her to go back to work and for us to pay for child care. The cost of child care was far more than she could possibly bring home. Plus, we have the (apparently old fashioned) belief that an attentive and caring parent would do a better job raising her than some rando child care worker who's trying to corral 10 other kids all day.

I don't mean that the nursing period is so much a differentiating factor for the outcome, but rather that if the parents chose to breastfeed, that is one and about the only biologically differentiated role between a mother and a father, thus needs to be accounted for in some way. Ideally men should take more of other child caring burdens during the breastfeeding, but that depends on various other practical factors, so I wouldn't call men up for failing to do that.
> Okay so non-cognitive development is ... clearly lacking in government supported child-care

[citation needed]

The study did not make any such claim; it only claimed that non-cognitive development is important. One would need to study the non-cognitive development across various child-care providers, measuring by price, caregiver education level, curriculum, and a wide variety of other factors to determine which (if any) affect non-cognitive development.

The problem could be as simple as improving the toys, games, and learning materials provided to the kids or as intractable as kids requiring a 1:1 caregiver (aka a stay-at-home parent). Or anywhere in-between.

There are 8 rows of holes, and the top and bottom "margin" seems to be about one hole high. A person would stand roughly two holes high, so most of the ground cover would be shin height with occasional knee height shrubs, which seems reasonable. The flag pole is probably set back from the front surface, so some of its height is obscured below the upper edge. There's probably some perspective distortion happening, too.

I've learned programming with C/C++ so I've always been comfortable playing close to the metal, and Rust ticks a lot of boxes in providing the same low-level strongly typed experience, with a ton of added bonuses: very useful compiler, memory safety, an actual ecosystem of packages that lets one focus on the product and not the build system..

At my previous company, a lot of engineering time was dedicated to maintaining the custom C++ build system, I'm glad to see "newer" languages formalizing this step: "make it opinionated by default so developers can get quickly up and running, but allow hooks into the system for later, when they have specific needs", rather than the JS approach of "batteries not included, nor screws or assembly manual, but hey you can build whatever you want !", which leads to decision fatigue at the most critical time of an idea's inception.

That being said, to answer your actual question: I haven't looked closely into them, but functional programming is still a bit arcane for my OOP-trained mind, it will take a bit of practice to think differently.

The problem is, it's configuration free until it's not. If you end up having to pass in a partial Webpack config anyway, how much time are you really saying?

The reality is, at this point, Webpack has become a powerful tool with a big ecosystem around it. Configuration is not that complicated. It used to be an absolute mess, but these days, the documentation is really good and there are many sensible defaults. It's worth learning without these wrapper solutions.

Maybe it's difficult to get the actual light out into the open air, but there's nothing stopping view dependant parallax from making an image appear "in front" of the display, with the annoying limitation that your object will still be occluded by the bounds of the display.

Failing that, you can easily bend lightwaves in open air with a strong enough gravitational field. So there you go, you just need a way to generate enough black holes and position them very precisely.

Or... a way to modify the density (and therefore index of refraction) within a volume of air, with perhaps, standing waves.
I don't agree with the practice, but a lot of bicyclists will readily pass car drivers around intersections (because cars are bulky and take much longer to safely navigate through an intersection) so you rarely lose /that/ much by poking around a block or two.

Either way, it sounds like you've given it a lot of thought so you're likely the least of my worries. Just imagine it would be your child on the bicycle and you'll probably do the right thing. (Short of picking them up -- don't do that.)

Taking time off from your career puts you behind your peers. That's no surprise. If women take time off to raise young children that hurts their long-term earnings. Again, no surprise.

If we want to frame it in purely economic terms vis-a-vis government:

Does the long-term increase in taxes paid by working mothers cover or exceed government outlays to provide childcare, especially in the early pre-K4 years?

Secondarily is there any negative effect on the children and if so can those effects be mitigated?

The study seems to indicate it is a net-win for the government because high-cost childcare only happens for 1-3 years but the earning power increase lasts the rest of a woman's career. I presume rational government policy would attempt to make free childcare tax neutral in this case.

In alternative terms you could see this as the government making a short-term (3 year) loan to cover childcare while being paid back in the form of higher taxes paid by the beneficiaries over the next 20-30 years.

Whether this makes sense for an individual couple is another matter. Whether the government should encourage new daycares or people to train as childcare providers is also another matter that bears some similarities to the universal healthcare arguments (eg that the government would want to encourage more people to train as doctors and nurses since the expected demand for services would increase, though true believers in the free market should expect the market to take care of such problems).

The tragically austere reasoning would be to reduce stress on caregivers in order to make improved children who make more efficient workers that are cheaper to run due to lower healthcare costs. :)

Population increases or reduction are more complex than simply a function of cost. They are also a function of time and quality of life. People in developed societies tend to have fewer children. I'd be inclined to believe that the absolute cost of raising a child in a developed country is orders of magnitude more than in an underdeveloped one. For instance. In general I will contend that we can support caregivers for altruistic reasons and yet not necessarily increase population growth. Depends.
I bought one of the first Raspberry Pi model Bs, before Raspbian was even around. The device blew my mind. Sure it was super slow, barely ran a UI (tho it did work!), and didn't have a lot of tutorials and learning resources, but it had an RCA jack and USB, so if you had at least a TV within 20 years old (available for $5 at almost any second hand store) and a mouse/keyboard, you had a computer for next to nothing! It also had HDMI as well for convenience. I do wish they'd bring back the RCA jack, but I'm sure they didn't remove it without good reason.

I think it's easy to get excited about the cool things we cool do with the pi, and I do. But remembering how unbelievably well they nailed their original mission of creating a low cost hackable computer that kids and students could afford. Something to teach the next generation who won't have access to the early Home PCs that we did, which were very accessible. Try tinkering with your laptop these days and you'll see how badly the world needs the Raspberry Pi.

I read an article a while back about a couple of americans who went to china and opened a "chinese" food restaurant because real chinese food looked nothing like the americanized "chinese" delivery food and they missed their sweet-&-sour chicken balls and fortune cookies. It flopped hard... until they rebranded and called it "american comfort food". It's always amusing to learn about the quirky dissonances between expectation of people from different cultures.

> SF is filled with the segments of the community that I don't identify with

I'm married and straight so I don't have much contact with the LGBT community in SF, but for some reason the few times have always been somewhat awkward. Imagine looking at marathon runners with funny costumes and then having to explain to your 5/yo not to be pointing and yelling at the naked guy with the rainbow cape. Another time my wife took my daughter to what she thought was a generic kids activity at a library and it turned out to be a transgender seminar, dumbed down to kids vocab level.

I've also found the gay parade in particular to be a bit surreal: the SF parade seemed more like a corporate sponsorship show and had a distinct "spectacle" feel, nothing like the communal street party feel of the Toronto Pride parade.

It almost feels like the culture here is that LGBT identity is this unusual curious thing to be on display on a similar level to the animal shows at the library. Just feels very weird, coming from Toronto, where people are generally nonchalant/indifferent towards sexual orientation.

Apple strongest competitive advantage is their ability to make people pay and it seems to have reach its limit because you cannot ask people to pay more than 1000 USD for a phone when more competitors have similar products costing half.

Sorry, that point has generated more heat than I expected. What I was meaning here (and said poorly) is that for society specialisation seems to work out with a net overall increase in productivity. If some specialise in childcare it should free others up to specialise in other fields and allow those specialised in childcare to look after more children than stay at home parents would.

I also should have stated that this is an assumption I was basing my next statements on, not a statement of fact. This was also just a generalisation used to reason from. I'm not trying to speak for anyone's individual situation.

I share your belief that a caring parent is going to be better at raising children than a care worker. I would choose this option myself if I were to have children regardless of the economics (here in New Zealand childcare is heavily subsidised by the government, so the numbers would be a little different).
That Viral Video of Alexandria Ocasio-Cortez Dancing Is a Meta-Meme
Engineering resources are not unlimited, so naturally new bugs and features will be updated only on master vs. 2 or 5 major semver branches, because 2-5 module Bs haven't bothered updating yet. If you maintain 5 separate branches, then you're spending that much more engineering resources for little benefit, because you don't have external customers. So the modules that haven't migrated yet decay under a state of deferred maintenance, which is a form of technical debt.

To avoid that, you do 10 migration commits so everyone is on the latest version. If you're going to do that as standard operating procedure anyway might as well make it far easier and have a monorepo.
