It is but it's quite straightforward to build your own simpler version using only Combine - that's what we're doing at the moment and it tends to work very well, interacting with Core Data has been kind of clunky though.

> I am looking forward to SwiftUI. I really hope that the documentation improves, though.

I've been on a project using it for the last 8 months both for macOS and iOS, I would honestly not rush into using it anytime soon. It's improved significantly since release, especially if you can target the newest iOS but requiring that is a hard-sell for most. On the Mac it's a different story and is much more neglected, macOS versions also tend to have far longer tails than iOS so it's a non-starter to try and sell a Monterey-only Mac app.

Edit: rereading my comment it sounds like I'm really down on SwiftUI - which I'm not, I think it's great when it works but there's a lot of rough edges at the moment and also quite a lot of hype.

The thing about math is that it just boils down to simple rules that have wide ranging consequences and interrelations.

To keep from being overwhelmed, pick a problem and try to focus on only the information relevant to that problem.

I sucked at math as a small child because the social message teachers give that math is hard did not really make sense in light of boring arithmetic so I thought I was missing something. Turns out I wasn’t.

Go into it driven by curiosity. Focus on building strong fundamentals; algebra and trigonometry are very useful. Then look into calculus or linear algebra.

Make sure to solve actual problems for practice. But spend plenty of time researching. Take notes. Write out all the steps in your problem solving so that you can debug any mistakes.

Lastly, have fun! There’s a lot of neat math out there, treat yourself to some research into whatever is interesting to you when you get sick of grinding on the fundamentals.

Physicisty type here! It's actually easy to calculate because it's so small.

If you dropped them side-by-side the difference would require factoring in the curvature of the Earth and would really be way below anything you might measure... If you drop them in series then yes that does have another effect... the actual acceleration should be like g(1+m/M) instead of just g, so if a ball is 0.6 kg and Earth is 6e24 kg the fall time goes like √(2D/g) and so for a 10s (500 m) freefall in vacuum it changes the time by 0.5 yoctoseconds? Way smaller than any clock accuracy as far as I know...

No the real inaccuracy is that the drag force in air will scale like the square of the velocity,

m dv/dt = m g – ½ ρ A v² c

Where c is a dimensionless geometric constant called the Drag Coefficient, you can handwave that for these rough sphere surfaces it's maybe 0.5 or so, ρ is the density of air which of course gets lower at high elevations, at sea level it’s 1.22 kg/m³, but decreases like 0.13 kg/m³/km or so. A is the cross-sectional area of the ball π r². If you pretend that these variables are fixed instead of changing then this is a soluble equation, defining U = √{2mg/(ρ A v² c)},

dv/dt = g – g (v/U)²
v(t) = U tanh(g t/U)

U is the terminal velocity. Note that for small times tanh( gt/U) ≈ gt/U and v(t) ≈ gt becomes independent of U and hence m...

So that's my pet peeve: The two things on Earth should fall side-by-side in tandem at first, then slowly the tennis ball should lag behind! That's not what we see in this simulation, unfortunately.

Thank you. The indexes are built on top of either Faiss, Hnswlib or Annoy depending on the settings - https://neuml.github.io/txtai/embeddings/configuration/#back...

I've primarily focused on single query times, which have averaged around 5ms - 25ms depending on the size of the index. Queries can be batched so query times wouldn't increase linearly. You could batch quite a few and still get subsecond response times.

All three libraries are approximate nearest neighbors but I know at least for Faiss, it can be configured to effectively be a precise query.
What I meant is that current grid scale lithium ion battery storage projects are designed for at maximum a few hours between charge and discharge. They are mostly for shorter window grid stabilization, not to store energy for days or weeks.

LiIon grid scale batteries are still very expensive as a long term energy storage solution, they are sized to provide higher value grid ancillary services, like frequence regulation.
If there were a science of user interaction, its second law could be called the Wide Angle Fallacy. When a disgusted user goes back to the designer saying, “Your system doesn’t perform the special function I need,” the designer’s ego is deeply affected. To regain the good graces of his customer—and to re-establish his self-esteem—the designer is likely to answer, “I can fix it in no time. I will just add another command for you.”

Later, the same man will be seen at conventions, meetings and workshops, extolling the virtues of his system, the “power” of which can be measured by the great number of commands it can execute. I believe this is usually a fallacy and users should recognize it as such.

There are so many questions waiting to be answered. He's plotted intraday versus overnight returns and showed that the former are larger. He claims this is evidence of market manipulation because overnight positions should be less risky. So demonstrate that by plotting the volatilities!

Flamewar comments like this, and others you've posted recently, are not ok and will get you banned here. We've had to warn you about this several times before, and unfortunately you've continued to do it quite regularly. Would you please review the site rules and fix this? https://news.ycombinator.com/newsguidelines.html

In particular, please stop the pattern where you get entangled with some other user you're arguing with, and then get increasingly aggressive toward them. That's absolutely not ok, regardless of how wrong they or or you feel they are, and regardless of whether they're also breaking the site guidelines.

Also, please don't use HN primarily for ideological battle. I'm seeing mostly that in your recent comments. We want curious conversation, not battle, on this site. Not only are those not the same, they're incompatible—for the same reason that having a tank battle and playing frisbee in the park are not compatible, or that boxing and dancing aren't. When an account is primarily using HN for battle, that's one line at which we ban the account [1, 2]. I don't want to ban you, so if you'd please fix this also, I'd appreciate it.

It would be good if you'd review the guidelines and take their intended spirit to heart. We want thoughtful, respectful, intellectually interesting conversation that gratifies intellectual curiosity. We don't want comments (and commenters) that are just out to defeat enemies—which I'm afraid is how your participation in more than one thread has been coming across.

This is an incredibly new development and is based entirely on prosperity.

For most of history of democracy and capitalism, individuals made altruistic choices for their own future generations - not for humanity, but for their own children.

It's only during the post-war boom (and only in the countries that were undamaged by the war) did automatic prosperity become the ubiquitous expectation.

And even in that context, immigrant parents made similar sacrifices.
This is “uncensorable” in the same way that “sovereign citizens” are immune from prosecution. Once someone uses it for something which is actually illegal, they’ll learn how useful blockchains are for prosecutors.

The underlying mistake is thinking about this like a game where you can make up rules for the government to follow. What actually happens is one of two paths:

1. You’re outside their jurisdiction, so anything will work because your local police don’t care. Maybe you have to avoid traveling to certain places or doing business with certain companies but you can almost certainly live a full life with minimal impact unless you’re doing something like leaking the secrets of a drug cartel or Russian oligarch.

2. You’re subject to their authority, which gives them a rich suite of tools ranging from arresting you, having ISPs filter DNS or network connections, launching denial of service attacks on your infrastructure, etc. How much effort they’ll expend depends on exactly what you’re doing and how authoritarian the government is, not the technology.

Since it isn't really clear, Handshake protocol is an attempt to create an alternative DNS without authoritative root name servers, where instead users auction names priced in Handshake coins, the initial bulk of which were gifted to various FOSS developers and organizations to try and keep rich people from hoarding everything. Instead of querying root servers for TLDs, you query a blockchain to get the records.

This guy figured out you can stuff Tweets into DNS TXT records, and chose to do it on Handshake DNS instead of regular DNS, since this one is on a blockchain, which I guess means even when a name record is sold to someone else and the current record is changed, the old record is still there in the blockchain history, so you can now never delete or edit a Tweet.
The major lesson of the Fed’s QE policy has been that QE does not put dollars into the economy evenly. Certain asset classes and professions get first crack at the newly printed dollars, and over time firms and industries specifically designed to capture printed money evolve e.g. wework.

It's a bit more specific than just being "faster" and "more efficient". There's two main advantages:

First, waiver of class-action rights. This is a big deal because there's a cottage industry of enterprising lawyers who do find a couple main plaintiffs, generate a suit on behalf of a large class against a deep-pocketed defendant, and settle for something around a dollar per class member plus millions in legal fees.

Second is a limitation on discovery and subpoena rights for plaintiffs. In a traditional court setting, you may be allowed to force a company to turn over extensive communication records and other documents, corporate executives to testify or be deposed, and even burden non-party witnesses (eg, part suppliers).

In many jurisdictions, companies that wish to use binding arbitration have to pay the entirety of the significant fees to fund the arbitration system (and in a timely manner). It's still worthwhile for them to do so, even if they aren't tipping the scales of justice one micrometer. With the exact same outcome as a court case, the arbitration fees are fully worth it to avoid discovery, better protect executives from being forced to testify, dodge class-action fishing expeditions, etc.

> You can’t stop it being added

It really depends what you mean by “you”, of course I can't, but miners can since they are the one actively adding stuff to the chain. In fact, they may even be legally responsible for what they add to a blockchain (IANAL though), and since miners are physical entities most of whom have a publicly known IP address, it may even be realistically enforceable.
Why not using DAX FS mode for Optane DC memory for instance and serialize the data structure by hand? I'm not sure how much performance you lose. That said the data store I'm working on serializes the huge persistent in-memory index to durable storage in a postorder traversal (mainly changed records in a data page Plus path copies) and atomically sets an offset to the main root, the UberPage to the new revision in a file. So, I'd say it's precisely what you describe :-)

Not included in this analysis is leakage rate... by which I mean ooze leakage.

I have found that some batteries have a much greater likelihood of leaking ooze than others (yeah Rayovak, I'm looking at you!)

Except in the case of crappy toys, the damage that this causes radically outstrips the cost of the battery.

As a result, I buy batteries not based on electrical performance, but track record in not ruining the things I put them into. I am very happy to accept 50% less energy if I can avoid destroying my $200 gadget.

The best explanation of anarchy I've heard is by debunking the common view that people think anarchy is when a a disaster happens and a warlord takes over - but it's really when a disaster happens and neighbors start checking on each other to make sure everyone is alright and see if anyone needs help. If the community isn't voluntarily doing it then it isn't anarchy

Yes, that is why many anarchists consider government a coercive system and seek alternatives to that coercion. Of course, coercion can't be eliminated, but we can acknowledge the right of legitimate self defense against that coercion.

Nice article, and nice analysis of the problem.

I have a personal theory that once a codebase gets complicated enough (no matter the language, no matter sync or async), you'll run into subtle bugs or performance problems that require a very deep understanding of all the relevant libraries in order to resolve the problem. One worry that I have with async rust is that the executors are so complex that the "baseline complexity" starts rather high.

If this theory is true, then one might expect async rust to run into such problems more often than comparable non-async code. I haven't personally written enough async code to have any data either way, except for a few unpleasant experiences while making errors when writing async code.

To the extent that this theory is a problem that needs solving, I don't think there is a solution. But I do think that, over time, weird async footguns will become less and less frequent as projects like tokio continue their excellent engineering efforts to plug up any weak spots and make things more robust in general.

I'm sure you could pay professionals to work in shifts to monitor stock prices 24/7.

Isn't that circular reasoning? "The stock market needs to close during the day because the end-of-day price is significant to a lot of things because the stock market needs to close during the day". Take the spot price at 00:00:00 AM as your end-of-day price and call it a day.
>To suggest this is punishing new teachers is ridiculous. If you don't like the salary schedule, you shouldn't have taken the job

Err, you have this backwards. If I don't like my company's stock vesting schedule, I can choose to go get a new job down the street with a completely different comp structure.

If a young teacher in LA County is frustrated that their school is rewarding low performers with double their salary simply because of time, your suggestion is they "shouldn't have taken the job"? Despite the fact that the Union has negotiated with the entire school district, and they have no choice but to leave the county at the very least if they want something different?

You see how the Union is actively harming the younger teachers by taking away their choices, right?
