THIS IS ALL WRONG! When working with tile you level of precision is 1/4 an inch. So the 2-5/8 tile is either 2-1/2 or 2-3/4. Either way divide by 2 and it is 1-1/4 or maybe 1-1/2 - both will fit so who cares.

If you are under 60 and not in a vulnerable group and got two shots you are already done. Biontech/Moderna both offer pretty good protection against getting seriously ill.

So no need to get Covid the "natural way". If you are fully vaccinated, you are fully vaccinated. As long as there is no new escape variant you are fine already.

The third shot might be pretty optional for young people, we will have to see. Still even if necessary, it is not like you have to get a shot every week, the third will probably last much longer.
Ask HN: Mathematics and Organized Knowledge
For any ordered system, there can be a mathematical description of its structure and relationships.

So, can human knowledge be organized into an ordered structure that can be used to statistically measure an individual person's state of knowledge? (A map of knowledge as a standard of measurement to evaluate a person's level of understanding)

I'm aware of Knowledge Space Theory and Bayesian Knowledge Tracing. I'm asking whether human knowledge, as a whole, can be organized into a tangible hierarchical structure of nodes, sub-nodes, etc. whose relationships can be mapped in a reasonably doable way.

To me, the use of mental models, first principles thinking, scientific reductionism, and the abundance of freely available knowledge (Wikipedia) would make this a not-impossible and very-rewarding task. If we divide knowledge into science (discovered) and philosophy (made), it'd be easier to organize scientific knowledge first, then move on to making the complex organization of history, philosophy, political science, etc. (As the saying goes, the laws of planetary motion are simpler than the history of Sweden).
My bank (Bunq) also has virtual cards and allows to track subscriptions. Pretty nice to have. It doesn't have an easy option to cancel subscriptions though, but I actually don't need that to be honest. Still, nice niche idea.

Interestingly, because you can get these debit cards and IBANs with the subscription, Bunq is often used by money mules and the like, giving Bunq a bad name in the process. Wouldn't surprise me if something similar happened here, even if just as a preventive measure.

I do think its strange Justuseapp.com allows people to get a virtual debit card with an address in USA, even when they're not in USA (their customer). Either way, if you're using this ("financial VPN based in USA") to steer away from US government you're doing it wrong. A proper use case would be to avoid PII getting leaked on all kind of online services.

Tesla v10 FSD Update Is yet Another Safety Disaster
I just built my MVP in a Next.js monorepo. We built the mvp in a few weeks and actually landed some real customers with it.

But I knew doing it in Rails or Django would've been faster, but I haven't got enough experience with either.

Let's say I want to create my app in Rails (or django). I don't need it to be pixel perfect, but I do want some flexibility around the UI. ActiveRecod is fine. Can I just plug this into the admin and customize as I see fit? I know Django has a built-in Admin, does Rails?

FWIW, I have used Django (without the admin) and tried learning Rails several years ago but it was too overwhelming for me. Rack middleware, the ruby syntax, the conventions—all of it seemed over my head. But if I can learn redux, react, etc, I feel like I can do Rails too.

Do you have any recommendations on resources? I want to learn how to make something that looks really good, is convention-based, lets me plug in my custom code when needed, and lets me prototype fast as hell.

A ton of huge stuff was in JDK 16 though, and seems most companies won't upgrade until LTS releases, so folks should be looking at JDK 17 as JDK 12-17 if they're in a corporate environment.

Records, multiline strings, pattern matching for instanceof, handling nulls in pattern matching/switch, sealed classes/interfaces, probably other things I'm forgetting.

I had never written Java before until recently, and thank god for JDK16 features. Only thing that made it slightly tolerable.
Are there real statistics on just how many people are being turned away? Hasn't it always been the case that people sometimes have to be turned to another hospital?

It's not "conspicuously absent from the paper". They have a whole group of experiments on this: "Experiments on anatomic and phenotype confounders" and conclude "Race detection is not due to obvious anatomic and phenotype confounder variables."

I am skeptical about the "strong encapsulation" and in general, of all cases whey people tell me about something: "you don't need it, it's better for you to do it other way".

Usually I know better what I need. There were cases when I needed to access the internals, e.g. fixing a prod issue.

A quote from Thinking Forth comes to mind:

> The newest traditional languages (such as Modula 2) bend over backwards to ensure that modules hide internal routines and data structures from other modules. The goal is to achieve module independence (a minimum coupling). The fear seems to be that modules strive to attack each other like alien antibodies. Or else, that evil bands of marauding modules are out to clobber the precious family data structures.

> This is not what we’re concerned about. The purpose of hiding information, as we mean it, is simply to minimize the effects of a possible design-change by localizing things that might change within each component.

The only reason it hasn't happened is because they had no legitimate competition until recently. In a healthy market they would have been forced to do so long ago. Capitalism and "market forces" only work where competition exists.

You are claiming that people who make predictions of this sort are not making a "serious" prediction. And I am claiming that you don't get to say that.

You may dismiss their predictions; you may feel they are worthless to listen to; you might have an explanation for why we shouldn't take such predictions seriously. I can agree with all that. But none of this makes my claim any less of a prediction.

My claim is that in the future people will have a certain point of view. That is what a prediction is.

I am confident you know that predictions can be false, and calling something a prediction doesn't mean "it will come true" or "it is more likely to come true than not".

I'm just puzzled about your use of the word "prediction" -- perhaps we mean different things.

> Why are young girls so awful to each other?

Why does this conversation always have to exclusively revolve around how young girls treat each other? Young boys are awful to young girls. Women and men are awful to young girls. The question you should be asking is why do we as a society tolerate people (of any age and any gender!) being so awful to girls?

The article is about Facebook, the company. Facebook isn’t run by young girls. And yet many comments in this thread are focused not on Facebook’s responsibility to (and profiteering from the exploitation of) girls mental health and are instead focused on blaming the girls themselves.

Seems more than a little backwards to me.
The unvaccinated are putting others at risk, including kids. I can't say the same about the obese or people who don't take their medication.
If someone were struggling with alcoholism, and I offered them an FDA approved shot to remove their addiction to alcohol, I would consider them fairly stupid if they refused it. Handling diseases and addictions is a long term struggle, not similar to a one time choice at all. It is orders of magnitude easier to get a covid shot than to rid yourself of an addiction.

The comment doesn't sound to me like blaming the girls, but just taking the core of the blame off of Facebook.

And it's really pretty clear that Facebook didn't create any of these problems and that removing it won't solve them. Facebook makes it easier for girls to bully each other in the same way that relaxed gun laws make it easier for criminals to shoot people. Or, as Londoners will tell you: "you can't solve knife crime by taking away people's knives".

The fact that Facebook profits from the issue doesn't make it their fault unless you can prove that they actively seek to make it worse. And even then, they can only carry the blame proportional to how much they made it worse.
I absolutely believe the importance of this specifically because the desktop is failing at that in todays standard. In other words, maybe there is an apple or microsoft to be created around turning android or ios devices into work stations. I think that would require a new vm, i dont think you can code html 5 app on such a device for example.
Yet I grow food in my garden (inefficiently) and play instruments for fun (not very well), because modern life is so convenient I can do those things.

At age 85 I might have regrets that I should have done more to preserve things for the next generation. Then again, we're terrible at predicting the future...

If you read the original article, Facebook employees felt, based on their research, that Instagram was worse for teenage girls than Snapchat or Tik-Tok.

"They came to the conclusion that some of the problems were specific to Instagram, and not social media more broadly. That is especially true concerning so-called social comparison, which is when people assess their own value in relation to the attractiveness, wealth and success of others."

"'Social comparison is worse on Instagram,' states Facebook's deep dive into teen girl body-image issues in 2020, noting that TikTok, a short-video app, is grounded in performance, while users on Snapchat, a rival photo and video-sharing app, are sheltered by jokey filters that 'keep the focus on the face.' In contrast, Instagram focuses heavily on the body and lifestyle."

So maybe they understand the dangers of Instagram better than you do?
I’m posting this again (previously posted https://news.ycombinator.com/item?id=28507916) because there has been a lot of development on the story since yesterday. This issue got a lot of attention and a hot debate sparked which included questioning the TC39 process as it stands. The issue was later closed and further comments disallowed for reasons of it being too heated.

Me personally am a little disappointed by the reaction of the TC39 members here. The way I see it is that a huge interest sparked around a topic and instead of embracing and celebrating this interest, the member decided to shut it down.
I had also heard a point for toothpaste involving the marketing: toothpaste advertisements, and all marketing imagery of toothpaste on a toothbrush, almost always show absurdly larger amounts of toothpaste than is effective or appropriate to use brushing teeth, trying to increase consumption by increasing waste.

Ok but if you're barely in the top 2% that would sound like you'd afford the worst in London - is it the worst you're going for or are you expecting to be the quality of what you'd get other places?

Obviously I don't know if you're barely or not, just since you said top 2% and not top 1% it might be you are just at the edge.

A clarification: Rust only makes this guarantee for certain types[1] which you would expect to be represented by a simple pointer under the hood (e.g., Box<U>, &T, function pointers) and for other types which can never be all 0.

Microsoft tried doing something like this with Windows Phone. It was OK, but the fundamental issue here is that the messaging apps themselves absolutely do not want such a thing, because it would commoditize them and keep the user away from revenue-boosting gimmicks and dark patterns. They will never allow it to be built. RIM was only able to do it before companies realized the value of messaging lock-in; even if it still existed in any real capacity today, this feature would not.
We do not have to think about weather, even the day-night cycle produces very strong differences in energy demand. Now what does the nuclear power house France do to counter this change in demand? Hint: it is (to 99%) not to regulate nuclear power. E.g https://energy-charts.info/charts/power/chart.htm?l=en&c=FR&...

There are limited sources of variable energy like some hydro, biomass, storage or ... (some) fossils. Nuclear is very bad as a variable energy source and therefore, aside for nuclear carriers, nowhere the only source of power. It would be nice if it were, but it is not.
