Anwsering my own comment cause I can't edit it anymore, but this article has started a heated debate on tweeter.

The author of "black" suggested that the cause of the slow down may be that asyncio actually starved postgres for resources:

I wrote a lengthy comment here about bike fitters. They can also help with this. It's however often more complicated than just a few measurements. They often have a special bike where literally everything can be adjusted (google retül bike), and then when the fit is done (~1h) they got lots of parameters that can be put into a DB to spit out bikeframes+gear that will work for the rider. However, my experience is that the system still needs a human expert to verify and tweak the results.

However, for a basic fit your method works. For instance when buying a Canyon they ask for your measurements for some things to recommend frame size. But this of course if very rudimentary and already assumes you want that model.

time trusting anything else than the state to handle health data

Why would you trust the state with anything? Didn't the UK govt sell health data to a Google owned company?
Sorry, I should have worded that more clearly: Only that science or truth that is doesn't contravene the current social order is allowed air, allowed to be talked about without reprisal and shunning. The degree to which this is true is a canary for how totalitarian and neurotic your micro-society is. The micro-society of universities generally seems to be becoming more, rather than less, rabid and paranoid.

A lot of it is like Bostrom's idea of the decentralized electroshock dystopia: even though a significant proportion of people are witches, everyone's afraid of reprisal for not actively hunting witches, so the witches-in-hiding hunt their own when they're unmasked.

But this is the way of things; this wave will pass, eventually, as well. And like the soviet scientists who kept their heads down and mouthed the party line, the secret iconoclasts will survive till the current order is replaced by the next, with its own peculiar tabboos.
I agree with you, so by zombie state I mean the languages are still being used, but for historic reasons (e.g. you don't want to rewrite), but no one really wants to start a new project in COBOL.
Isn't it "juj" in Spanish? :)
And state doesn't care about money ? I've heard several places talking about bumping insurance for stuff the moralising politicians find easy to wilify - from stuff like dietary choices and whatever the diet fad seem to be popular (nutrition being the scam that it is basing mandatory public policy on it is ridiculous), over drinking to smoking, illegal drug use (recreational or performance enhancing) etc.

I don't want anyone collecting data on me - I should be in charge of disclosing the information - there is an adage in the PED community - if you mention steroid use to your physician and it gets on your record the next time you brake a bone or catch a cold it's going to be "steroid related". Probably the same shit for rec drugs or regulated nootropics.
> for everyone / my next app is an interior design / home control app.

That's a good point but really not "for everyone". Agreed that for a one shot app like this, pay once is the model that works. Although one could argue that you still held the customer data captive as soon as they get a new phone and the app is no longer compatible.
While Facebook and MySpace are different in many ways, the average lifespan of a S&P 500 company is below 20 years.

Facebook could very well be an outlier. If it isn't, it could definitely go away in the coming years.

In any case, that shows that its revenue/income is not a predictor of anything. When a company spirals down, it does so at an accelerating rate and can quickly burn through any amount of cash.

This case can be framed more like "an american company suspended an american account of an american citizen to comply with Chinese local law." Operating in China doesn't necessarily expand its jurisdiction into the US. What Zoom should have done is blocking participants in China from the meeting created by Zhou and Wang rather than suspending a US citizen's account.

For the case of Gitlab, Google and Gitlab are both US based companies so it makes sense to comply with the US law.
Apple has a talent for putting themselves right at the center of important technologies. I wonder if this strategy plays out as integrated medical devices and a full-blown healthcare platform. Their reputation for top-notch hardware, good UX, and their shift towards in-house SoCs gives them a serious edge there. Everything about their brand feels well suited for healthcare, and IMO they still don't have a killer enterprise app. This could be what Watson was promising to be.
Of course, I used that phrasing to highlight the fact it causes less conflicts of interests (albeit not none).

That thought did occur to me as well but, in taking the article at face value it's most certainly some core aspect of their banking systems at the very least...

If they are intent on replacing the mainframe then, imo, MongoDB would be a bad choice but who knows... the new, challenger banks don't use mainframes.
What's wild about this is that Mongo isn't even in fashion anymore! NoSQL has been supplanted by NewSQL, and relational dbs are in season again. Even if they were trying to follow the trend, they'd be a half-decade behind.
Improving our policies as we continue to enable global collaboration
The hot path is the time between receiving market data from the network, and reacting to it by potentially sending an order. It's typically a thread constantly polling events from the network card.

In that path the rest of the world does not exist: you are interacting with an exchange, possibly multiple exchanges, and that's it. The rest of the world doesn't exist. No ZeroMQ or Kafka or whatever.

After you send an event, you can set a flag or copy some data structures for another thread of lower priority to do some house keeping. This might include sending an update on some messaging system, yes. This can be something like TIBCO RV, or a proprietary equivalent, or perhaps the ones you mentioned.

But the bottom line is: when doing low-latency, high-frequency trading you don't want to do anything that is not strictly required in the hot path. You must read the message coming from the market, very quickly decide how you want to react (i.e. send a new order or update an order, at which price point, etc.) and that's it. You will in fact even avoid computing too much stuff here; you would have pre-computed as much stuff as possible to be ready to very quickly do a lookup and maybe some trivial computation before making your decision.
This really kills discovery. Seeing an upfront price without the ability to trial the app really dissuades the user. On top of it, refunds are tedious to obtain and you can do it only so many times.

In the past I've edited titles, carefully crafting them to give a better indication of the content, only to have people complain that the title has been changed, and subsequently to have the mods change it back.

So I've given up even trying to put any thought into the title ... if the article seems like it would, should, or could be interesting to the HN community, I post it.

I've been trained not to put any work into it.

Companies used to serve multiple stakeholders that included, employees who worked for them, communities they were present in, customers they served, etc. in addition to stock holders. Slowly, slowly, the definition of stakeholders has been shrunk and reduced to stock holders and responsibilities reduced to maximizing profit. Of course these stakeholders and responsibilities are being further reduced slowly slowly to where companies only exist to benefit large shareholders and corporate executives.

I am guessing you might be young and may not be aware of history of corporations.

Well, 'huh' is basically a grunt.
They must have missed Swedish. We don't have 'huh', we have 'va'.
One possible explanation is that someone thinks it's their email address, they've forgotten the password and are annoyed that they're not getting the 2FA code on their phone..

Novel is often a matter of perspective. For example a company with no experience in GraphQL might want to integrate it, they don't know how long it will take because it's novel to them.

I think that NoSQL and SQL are so much different that they will equally coexist, in the same way that languages that are used for very different purposes like Java and Javascript can equally coexist. However, it is unlikely that we have 5 different equally popular languages for one specific domain (e.g. systems programming).
I'd expect many more words to exist in all languages. It would seem that there is a core set of words that are absolutely fundamental to any sort of spoken communication (yes/no, for example), and would be very surprised if this word "huh" is the only one so far found to exist in all languages.
2 problems. let us agree china law has issue, can zoom block any account traffic to china. But you note google and Apple has no such issue.

More problematic and deeper issue is how the overall game work for chinese market access and free world market access. As only China sanctioned account can communicate with china but you can use the channel for most, it has an advantage move others have. The market access to billion. As there is no equivalent they will take over a significant percentage of the market with sanction and freedom of speech as a cost. If it connects with india ...

Have to stop that kind of WHO and world trade chinese model, otherwise the free world would be in trouble.
Sure. Couple of points:

* Lastfm has an API but it's not great and an API is different to a dataset. I want to have the data available in my own DB, not have to make requests for whatever I might need.

* You can't get youtube links from the lastfm API, you have to crawl the tracks pages.

* The tags on lastfm are a folksonomy not a fixed taxonomy like musicbrainz

I have used [music-map](https://www.music-map.com/) and last.fm together to make a [playlist generator](http://playlist.hallofbrightcarvings.com.au) but I'd like to be able to do the same kind of thing without having to crawl third party sites.
I'd also like to know that there was a music database of listenable music that was kept up to date.
I’m using the Watch and with my iPhone. The Health and Activity apps work great together.

The visualizations are clear and understandable. For example, I’m significantly less active this spring than last spring—average of 2.2 miles walking per day in 2019 vs. about 1 mile in 2020.

That’s mostly due to stay at home orders due to COVID-19 the past 3 months. Once the weather got better and the number of cases subsided, I started taking walks in my neighborhood due to the actionable data I had.

Remember, the Watch and the iPhone can do machine learning on the device.

What’s missing is an easy way to do more advanced health data processing on my Mac if I wanted to.

I’d like my public health department release an app for COVID-19 exposure notification, using the Apple/Google API.

You could also envision broad clinical trials of treatments for COVID-19 using these components.
Siding with governments, instead of people is wrong. Not a surprise though, Zoom can do anything for money and its position. It is my wrong though, to wait for some kind of soul from corporates.
Lol. Just lol.
Relax HN guys.. this is the reason for this:

"Local requirements for each country will be built into the application, but there's no need to maintain separate data models or separate databases anymore. We could easily design the global data model and database using the MongoDB JSON schema model. That brings data from all operating countries into one database and the application can run on just one database. Which is a lot of reduction in resource and maintenance cost."

Is there any Database that can do this? other than MongoDB? I am hearing about data corruption in MogoDB, I believe that is due to bad, out of the box settings, which I believe they would have mitigated when using in cooperation with MongoDB company (which I am sure they are).
I would love a source for this.

And why is that relevant to liking spy gadgets?
GrannySmith: macOS app to backup Photos.app with shared albums, comments
The thought experiment is bad for the same reason, which you appear to agree with. The hashes are not secrets, it's just that passwords are pretty bad secrets. If I gave you an RSA modulus in which you know one factor is chosen from a range of a few trillion primes, the public key could be broken if public. The fact that typical user-chosen passwords are iffy secrets doesn't make the hashes secrets as well.

The choice to use password hashing is in effect an admission that they'll still be secrets. We are only using a specialist password hash

No, as you say yourself, we'd still hash if the passwords were random strings. Which turns them into non-secrets. The specialized hashing is an admission that many passwords are guessable. It sorts of sounds like you want to forklift your own terminology into this using the fact that user-selected passwords can be guessed.
Is it important?
The level of control they maintain over the devices after you have paid means I don't feel I am left alone. I feel I only have the rights of renter not an owner.

They do eventually use this power to force you to buy a new house. They use it to mark perfectly capable devices as obsolete e.g. why is a MPB i7/retina/ssd with discrete graphics now being marked as obsolete? Why is an iPad4 not allowed ad blocking with no chance to install an alternative open OS?
What and make them accountable? Not a chance.

I can also suspect they did it on purpose to loose some data by accident. What could possibly go wrong.
Maybe it's the french in my talking, but I really have a hard time trusting anything else than the state to handle health data.

I'm not French, and also feel the same way. It can also due to the fact that is is the center of all the political focus and other stuff. In general US has worse data protection polices than other developed nations (of course still better than country like China).
Yeah but they do not recommend using that. I think the one nosql afficianado in my team spoke with mongo support and they recommended reassessing our document structure for it. (So a migration after all... )

Also in their blogpost [1], about $lookup they say:

We’re still concerned that $lookup can be misused to treat MongoDB like a relational database. But instead of limiting its availability, we’re going to help developers know when its use is appropriate, and when it’s an anti-pattern. In the coming months, we will go beyond the existing documentation to provide clear, strong guidance in this area.

I'm gonna play the devils advocate, and say that money _is_ more important than morals. And it's because americans have a lot of money (collectively) that they can enjoy having high morals.

So i don't disagree that zoom is lacking in morals, but i also have to agree with what they did - for it is the only course of action that leads to them "winning" economically.
Well, I think Postgres will remain a very safe default choice in new projects for most organisations for a long time yet, because the skills to work with it are common and relatively cheap.

However, Crux is much easier to justify with stakeholders if you have a complex problem revolving around ad-hoc graph joins or bitemporal queries & audit requirements. Or if you simply have high single-threaded transaction throughput requirements. Postgres in particular doesn't have pleasant answers to this intersection of problems.

I think the tables will inevitably turn against currently-safe choices life Postgres though, as systems like Crux are going to continue to be able to take advantage of the latest and greatest ideas, relatively unencumbered by decades of antiquated design decisions and legacy code. This is where the whole Clojure philosophy really shines in Crux, as all the layers interact through clean and composable Clojure protocols that facilitate new kinds of database modularity. These protocols allow the community to take advantage of whatever wonderful cloud services they might want to use, without any additional ceremony to interact with the core development team.

EDIT: Finally, as new generations of developers emerge the pressure for the industry to standardise on a better relational query language will build. Fingers are crossed for Datalog!
Great explanations!
Fair enough. As for A14, maybe we know more after WWDC.
I think an organization should be able to deliver on what it promises when hiring someone even to an intern and both parties expectations should be expressed in good faith as clearly as possible. Frankly if someone told me they were cleaning toilets unexpectedly in their software development internship my advice would be to look for ways to get out of that internship if they can because engaging with that company is clearly a waste of time.
"Linux/Unix shells,"

On the other hand if the work is done on Windows it's much better to learn that platform than pining for something else.

Go with whatever is platform specific, and available out of the box. Avoid complex configuration packages just to get the specific interface flavour to the computational substrate you would prefer to use privately.

The reason is, if there is specific computational platform that the employer is using, you are much more helpfull to all around you if you operate with the vanilla settings rather than try to find something more special.

Privately try to find the best methods that work for you, in public, collaborating, try to find the most simple and straighforward method of contributing. Simple in this case does not mean a kludge, but it may mean a few extra lines of code or configuration here and there.
if you switched 'Zoom' with 'Google' in the above, would you have made a different argument?
I have worked in a German bank and the bundesbank does regulate on very high-level decisions. f.e., systems which do financial crime monitoring need to be compliant with their rules. Access to pre-production should be limited.
I love XKCD, but that strip is philosophically and historically ignorant.

Free speech isn't the First Amendment. Free speech is a broad foundational principle of liberalism, and the First Amendment is just an encoding of this principle in the context of the U.S. government. But go back to Mill's "On Liberty" and you'll find that he was just as concerned about threats to free speech stemming from social disapprobation as those from the government.

Anyway, I prefer this modified version of the strip: https://pbs.twimg.com/media/ECqxDQGVAAAXUgK?format=jpg&name=...
From the article, it looks like they are replacing separate DBs used for each country.

"Local requirements for each country will be built into the application, but there's no need to maintain separate data models or separate databases anymore. We could easily design the global data model and database using the MongoDB JSON schema model. That brings data from all operating countries into one database and the application can run on just one database. Which is a lot of reduction in resource and maintenance cost.
"

Are there any other schema-less databases out there that is better than MongoDB? If not I believe it's time for someone to build it.
