> all signs indicate gravity can not be successfully described as a quantum field

That's not quite correct. The quantum field theory of a massless spin-2 field was developed in the 1960s and 1970s and is perfectly well-defined. The problem with it then was that it is not renormalizable; but today basically all QFTs are viewed as effective field theories anyway, which means not being renormalizable is not a showstopper.

The real issue is that we have no prospect of measuring any quantum aspects of gravity now or in the foreseeable future, so there is no way to test the QFT that has been developed against experiment.

> Gravity has properties such as having its interaction strength grow with the amount of charge (energy), which is very different from the forces described by quantum fields that have constant interaction strength.

This is not correct either. The coupling constant of the massless spin-2 field is just Newton's gravitational constant (modulo some constant factors that depend on your units). The fact that the total interaction in a specific case varies with energy is no different from the fact that the total EM force between two charged objects varies with the charge. Energy is the source for gravity just as charge is the source for EM; the source is not the same as the coupling constant.

> To get antigravity, you need to find a way to have negative energy without it making the vacuum unstable.

Agreed. And as far as we know that is not possible.

> All this suggests gravity is not a fundamental force

This is quite possible, yes, but even if it were true it would not necessarily make the spin-2 massless QFT I referred to above invalid; it would just make it an effective theory that emerges from whatever is the next level down. (Which, as I noted above, is basically how we view all QFTs today anyway, including the Standard Model of particle physics.)

> The closest to an "antigravity" in general relativity is the cosmological constant, thought to explain dark energy. Its tiny (10^-122) positive value behaves like a constant negative energy attributed to the vacuum itself, driving the exponential expansion of space.

No, a positive CC does not have negative energy. It has positive energy and negative pressure. The effective source in the Friedmann equation is the energy density plus three times the pressure, which for a positive CC is negative (because the negative pressure outweighs the positive energy density).
While this is undeniably true, deferring childbirth the length of a traditional full-time undergraduate program immediately following high-school

Unfortunately, that's not how this works. If it were, then the article wouldn't be citing early 30s as the age at which educated women have kids.

How this works is that a poor woman from a bad neighborhood in her teens is happy if the guy doesn't beat her, isn't a substance abuser and has a job at all. Then she gets an education and her expectations change. Of course, he won't be a substance abuse. Of course, he won't beat her. He also should have a professional job, dress well, and have certain other appealing traits. Her expectations go way, way up.

In most cases, she also is unwilling to give up her career. She didn't get a degree to become a homemaker. Two career couples face significant challenges in finding a city where both careers can thrive.

Things get vastly more complicated and it takes time to find the right guy, among other things. Some of these women start trying to arrange for a child in their twenties and don't get one until their late thirties or even their forties.

Julie Numar was quoted as saying she sometimes wished she was brave enough to have an accident. She married a Texas businessman and had her only child in her forties. She was soon divorced and raised the child alone.

There are good things about getting an education and career as a woman. But for most women, it complicates the hell out of the desire to have kids. Those complications can mean it gets put off and put off and put off.

But I think I'm going to walk away from this discussion for now. It's an overwhelmingly male forum. The issues involved in waiting to have kids that so many women find agonizing are being trivialized. I'm being attacked and dismissed. The basis for my knowledge is being attacked as irrelevant. Etc.

Y'all have fun as men hashing out how women ought to view this issue.

I don’t know, I feel it connects and grounds us to know a thing of our past. I like to ask people about their ancestry as part of bantering and I’ve had a lot of interesting conversations that way.

I’m a fourth generation American of Eastern European Jewish background and I’ve been able to track my ancestry back into specific countries in Eastern Europe via documentation I’ve dug up on ancestry.com but haven’t gotten further. I’ve found it a fascinating exercise. I have not been able to determine the source of my surname (Soffian) which still remains a curiosity for me. Sometimes you uncover interesting artifacts. I learned I had a great uncle who immigrated to America from Romania aboard the RMS Carpathia in 1904. Eight years later in 1912, this would be the first ship to come to the Titanic’s rescue, and six years after that would itself be sunk by a U-Boat. My great uncle had left Romania likely to escape anti-semitism. He’d eventually find his way out to Denver. Sadly, he’d die in 1918 (the same year the Carpathia was sunk) at the age of 25, very probably from the flu.

This was him btw, along with his headstone and declaration of intent to become a citizen:

They could have bought something off the shelf. Not sure what was the value in building everything from scratch
They could do lots of things, but absent any evidence that they're likely to, it's just wild speculation.

And it's not "sideloading." There's no other local device involved. Once you've flipped the "unknown sources" switch, you just go to a website, download, and install, same as you would on a desktop.
What do you mean by "trolls"? Someone who disagrees with you? Like half the country is "trolls"?

And what stops you from simply unfriending these trolls, if they are so toxic?

I'm not buying that narrative at all. What I think actually happened is that groups of people always had irreconcilable differences, but these groups were mostly physically separated, because people tend to form bubbles of like-minded people. But then FB came, and everyone's opinions became visible. Half of your coworkers that you went out drinking with turned out to be Trump supporters or antivaxxers, and that just makes you and them angry.

The solution is to stop demonizing the other side, and start having rational conversations. But good luck with that.

P.s. Calling them "trolls" will only drive them further away from your politics, you're helping Trump to get reelected.

That is in no way different than REST:

1. (same)
2. Based on the screen designs and workflows, front end dev team writes the REST contract that they want. They mock the endpoints (i.e. using nock [0] or Angular's MockBackend) for the contracts and come up with the DTO definitions.
3. Backend folks start implementing the REST endpoints by orchestrating microservices (or by creating a REST service facade for an existing REST API).
4. Once the backend REST endpoints are done, switch out the mock endpoints for the real ones

There is no need or benefit for using GraphQL here, all this can be done with REST already. Tooling around REST is great, i.e. you could use TypeScript to generate .d.ts files for your REST Dtos based on the swagger API schema [1]. Or with plain JS, use a JS runtime library that validates the DTO schematics/REST contracts (both your mocked ones and the real ones returned by the backend) with i.e. joi [2].

"We can't afford that" was the default phrase growing up. I didn't push back, but I also didn't really learn (so to speak). Every one of my siblings (myself included) followed a similar pattern: as soon as we started making money, we bought what we wanted (because we finally could). We were only really taught that "no" was because one couldn't, not because one shouldn't.

My social experiment with my own children is still very early, but we've taken to using the phrase, "we don't think that's worth our money." Typically followed with, "you can spend your own money on it if it's important enough to you." Cheap crappy plastic toys that they're going to forget about in a matter of hours? Not worth my money. Candy at the checkout line? You have a 50/50 chance of convincing me (see above; I'm still a sucker for candy).

The other side of this was growing up we bought the cheapest of everything. On one hand, I can't go to the grocery store without looking at per unit pricing (which is advantageous). On the other hand, I have a hard time choosing between more expensive quality and less expensive junk. Some things are worth spending the real money on (our tent that we bought from REI will last forever; the Coleman tent we bought early in our marriage lasted for one season). But in all honesty, I'm still learning which things fall into the "buy it right and you only buy it once" category.

And when we're invited to fancy dinner parties and eating fancy food, I can't help but think, "I wish they just had a stack of pepperoni pizzas..."

>Agreed 100% + add publicly backed financial support.

That's where you go off the rails.

A girl from an impoverished background, whose only fault is that she is not a mom, has far more need of "publicly backed financial support" of her education than an upper middle class mom. Publicly backed financial support should be either restricted based on need for everyone, or it should be unrestricted and given to everyone as a matter of course. But telling a girl that she has to have a child before she gets access to this particular pot of money sets up the same restrictive environment and lack of "choice" that you decry in the "evil patriarchy".

If you know your queries at compile time, then you can register each query with the server when you build as the hash of the query. Then clients only have to send up the hash and the server can look them up in its registry; plus you now have an easy way to cache (cache based on query hash plus user). If it's the first time you've seen a query, you can hash it and add it to the registry as well.

Ask HN: Sites or tools to help family member sell stuff online
A family member is really good at physically itemising and categorising car parts they salvage from scrap yards.

These parts are generally very specific to certain vehicles (VAG group), e.g. motors for dimmers, ECUs

Selling them online you can make a nice bit of money however it is very time consuming

At the moment I have to create listings on Ebay/ Gumtree etc for stuff they want to sell.

I've tried training them to do it themselves but still struggling. We tried making a spreadsheet of inventory and a external hard drive of photos taken of parts.

I had a look online but couldn't find any suitable software.

Are there any tools or apps that can help them out, so I don't get bothered as much :) ?

It is - it is defense in depth. The application should be secure, and there should be steps to secure it. Especially because a secure application can protect a less secure network setup.

But on the other hand, the server or the network should not trust the application to be secure at all. The infrastructural setup should assume the application to be an <exec($_POST['do_me']);>. And that's why the application should be isolated on a system level, on a network level, and as much as possible. That's the good part I mean - the part that worked.

I think the difference is somewhat slight but actually really critical.

With REST, a common pattern is that you have our RESTful APIs return "business objects", but then down in the UI layer of the app you have a bunch of logic to turn these into "presentation objects". There are a couple problems with this:

1. If you have to support multiple front ends, like Android and iOS, you have to dupe all this logic.
2. If you have native apps, it makes it MUCH more difficult to change your backend APIs without breaking things.
3. Related to #2 above, GraphQL provides a much better paradigm for maintaining backwards compatibility than REST.

What other folks have said is somewhat true, with GraphQL a lot of what you do is "push up" code from the client up into the server. However, especially with native apps where you can't necessarily control when users upgrade, it is a huge benefit to be able to update that code serverside instead of clientside.

> To fetch all the data that the app needs to render on a single view, the code would only need to make a single API call to a graphql endpoint and you only have to deal with a single, neatly formatted response.

If the frontend devs come up with the GraphQL schema definition, they could also come up with a single REST request definition with very specific DTOs needed for that particular view/workflow. You would have the same single, neatly formatted response (caching included). There is no difference what technology you use here, as long as your API is designed UI-first and your API design (or the REST facade for microservice orechstration) is developed according to the UI.

If you go API-first, you will end up doing lot of REST calls to get the data you need for your view, but you would encounter the same problems if you were to model your GraphQL queries API-first, before you design the UI workflow.
