Here's the thing: I implemented exactly this for a side project where I needed users to be able to express simple logic for custom data handling rules. Here are some examples:

level = new Expression(['map', ['char', ['tail', 2], 0], {'=': 1, '-': 2}])
body = new Expression(['parse', ['trim', ['body']]])
name = new Expression(['replace', ['trim', ['body', 1]], /[ \t\r\n]+/, ' '])
target = new Expression(['first', ['body', 2], ['body', 3], ''])

The arg to `new Expression` is a Javascript object (i.e. can be sourced from JSON). The first element in each nested array is a function name/operator. It was absolutely trivial to implement. All the functions are implemented in a few lines of code within cases of a switch statement, and nested expressions are handled recursively.

For me this is just a temporary throwaway solution while I work on other more critical stuff first. I will replace it with an s-expression based DSL later. Like JSONLogic, it won't be Turing complete.

It just seems to me that JSONLogic is making a huge deal for what's really just a small reusable library.
> Or, better yet, make a database and have cities provide feeds of changes/permits/closures.

"Sorry, I know you crashed, your car's on fire, and you're bleeding out. But I need to get this road closure form submitted before I can help, or a self driving car might ignore the stationary accident and make things worse. Ugh, 5G's not working today... hold on..."

The cars must be able to handle random, unexpected events happening without maps, and without external guidance. A wheel falls off a truck in front of you for metal fatigue reasons and is bounding down the road - that's a thing that happens, and a thing that in no way will be reported before it becomes relevant.

If a self driving car can't handle this sort of thing (or an accident and coming on a flagger) autonomously, it has no business being allowed on the road.

And if it can - then there's no need to have a centralized database of weird things, because it can deal with the range of events autonomously.

If the CCP didn't have such a startling surveillance system and tight grip over any international narrative, I'd be inclined to agree with you.

But they have done themselves no favors in their handling of the situation.

I'm not sure the coverup would require a vast network of people. Maybe 1-2 dozen in a lab, max, (depending on who knew which experiments were being done) and a bunch of CCP members who I would not be surprised are tight lipped.

The counter questions are equally as troubling.

- Why haven't we found the host species? Typically it takes a few months, but we're going on 1.5 years. You'd think the CCP would have it very high on their priority list to find.

- How did this virus mutate a series of genetic sequences, none of which are found in other corona viruses? The series of mutations in SARS-COV2 seems very unlikely to have been a natural fluke.

There's a lot of questions here on both sides.

For me, I'd still put it at 50-50. I will not be surprised if a smoking gun is found one way or the other.

Arguably many of those legacy students provide more upward mobility to their peers via culture and opportunity than the middle management jobs those peers will graduate into. Let's say for a moment efforts like this manage to succeed at removing all cultural advantages, on what basis should students and people in general compete, and on what principles should communities organize themselves?

It's as though nobody has asked what qualities policies like this optimize for. Equality is what you have when you remove distinguishing qualities, so that's not really the thing. Justice presumes a crime, which kids have not committed. To me it seems like a cynical gesture aimed at destroying wealth instead of creating opportunity.

I also have almost no knowledge about dark matter in physics, and maybe I am a complete moron. But what do you think is more likely, there is this matter out there that no one has been able to find in decades of searching, or the mainstream assumptions/math on gravity are wrong/incomplete?

> there is a large chasm between discovery and information that is widely known and accepted among the population

There are even more extreme examples of this. The Moscow Papyrus is from 01850 BCE, and it explains how to calculate the area of a hemisphere from its diameter and how to calculate the volume of a truncated pyramid, so this information had already been discovered 3870 years ago—perhaps for many centuries.

Yet what fraction of people today know it? Try asking your taxi driver next time you're on vacation in Perú or the Philippines. Heck, I don't know the pyramid-volume thing myself! I'd have to work it out by integrating a quadratic.

(I recall that studying the calculus as a kid was a bit of a transition for me, because for the first time I came face to face with the realization that most adults' intellectual development was arrested around the year 01583 for some reason. It wasn't that they took a long time to grasp differentiation, or that they had some weird irrational belief at odds with reality, but that they just stopped learning and never grasped differentiation in the decades and decades they lived, converting themselves into intellectual dwarfs. I was still young enough to imagine that somehow I would avoid this...)
The industrial revolution was as much a product of economics as technology. If wages for lower-class workers hadn't been nearly so high, the technology might have come and gone without making much of a ripple. In fact, there's an argument to be made that it once did exactly that. Steam-powered machines were known to the Romans, and seen as a stupid novelty.

Disclaimer: I don't know English history well enough to put together a better explanation, but I'm sure this has been the subject of a number of PhD theses. Maybe someone can point to a source that goes into better detail.

>...but does anyone else mostly care about IOPS

IOPS helps, but for the average user, hundreds of thousands is already functionally infinite. What matters at this point is latency. Where you really feel that is Queue Depth 1. Where you read a file that points you to other files, that point you to other files, etc. That is the exact case where the computer is still making you wait.

This happens when you start your operating system, it starts services, you launch apps, etc. Driving that latency down is the biggest improvement you'll ever see past where we are today in terms of IOPS and throughput.

This is where the latest Optane actually shines. Optane doesn't win on IOPS or throughput, but where it shines is its crazy latency (delivered at relatively low power levels). Where latencies are 10% of that of even the highest end PCIe 4.0 NVMe SSDs. Do something like launch 20 applications at once, and it'll be done in a fraction of a time compared to even something like a Samsung 980 Pro because of latency being more around 10 μs instead of 100 μs.

PCIe 5.0 SSDs will cut latencies down to where Optane is today, but driving latency under 1 μs is where we'll get into a new level of crazy.

If a woman has 3 children at those odds, there is a 99.8% chance at least one child will live. If she has 4 children, it goes up to 99.997%. Having 6 children is clearly an overcompensation given this level of risk (99.9997% of one or more out of 6 living.)
Have you considered the possibility that it first appeared in the vicinity of a lab that experiments on similar viruses is because if it had appeared elsewhere, there would have been no sufficiently-equipped lab to isolate it? This is the streetlight effect: you find things where you (are able to) look for them.

In other words, it couldn't have appeared somewhere far from a properly-equipped lab, because there would be no properly-equipped lab to detect it.
The books have been a staple in our household as well, and I echo other people is saying that this a loss of a true talent. One thing I thought I'd add to the conversation is that a series of very well done short films were made based on some of his books.

Very interesting, thanks. I still don't understand how you handle capture groups in loops though?

My interest was for high trip counts but I think there's just a bug for any trip count:

let matcher: Matcher1<_> = regex!(br"(.){3}");
println!("{:?}", matcher.match_ranges(b"abc"));

I expect this to capture the 'c' but instead it captures the 'a'.

It won't happen until cars can talk to each other, think of how ants walk in a line and follow each other around an obstacle.

Car A (driven in manual mode) tells Car B (FSD) that tells Car C (FSD) that tells... Car Z (FSD):
"I stopped at a stop sign in stop & go traffic at Lat/Long xyz while I spotted a human in the middle of the road. This is marked on my maps data (updated overnight) as not being a normal stop. No new data was detected except the human standing and a human laying on the ground."

Car B, C, D... all confirm the same until Z passes the area and sees no more humans (they've been moved). Car Z tells Car AA all good here, proceed as normally.

I'm just rambling now, but it's truly how ants operate. Draw a line of chalk in the middle of their "line" or walking patch and watched them avoid it and find a way around it. The difference is all of these cars will feed a true neural net of public data of live road conditions, accidents, etc. A possible privacy nightmare, but these are different times.

>Cool story and all, but it does have to do with poverty level

Somethings I just don't volunteer as they are private, but since you asked in this very public forum:

>Did you worry about food or housing situations

yes

>have to take care of the household and siblings cause parent's were working

yes

>deal with substance abuse of parents

luckily, no. but abuse from parent, yes. parents with undiagnosed medical conditions, yes.

>or any number of things that are common experiences among poor families

yes

>You're basically saying your material conditions didn't matter, which is just untrue for most things.

To quote the Dude, "that's like, your opinion, man". There were definite obstacles to overcome. I was able to, others are not. I'm not judging anyone for not being able to as situations are different, yet you seem to be wanting to judge me. My economic situation changed as did the economy dictated the earning ability of parent's jobs. I was taught how to talk to people that came to the door looking for the "adults" or called on the phone (before we finally went without a phone all through my high school years). Did I live in the ghetto? No. One of the better financial decisions my parents made and were able to do was built their own house. Not paid a builder, my dad and grandfather cut the wood, swung the hammers.

What was your situation like?
I think you're right, but it's not in Apple's ethos. As an example see the Apple Magic Wireless mouse that has its charging port on the bottom specifically because Jobs didn't want users to ever use it as a wired mouse.
> When you say "China", do you mean the Department of Health, or the Department of Defense, or the Department of Trade, or the Chinese government, or the Chinese people, or some Chinese guy?

We call this deflecting. And it's a rhetorical device used when you are on the wrong side of the argument.

And the answer is "All Of The Above". All parts of the Chinese government leaders see very little problem with executing those who might upset their status quo.
It may be tangled up in the number of children. Spreading resources over more children may put them all further into that 12% category?

Anyway it seems to be true that child mortality has dropped across the board. US child mortality used to be almost 50% (in 1800). Now its around 0.7%. Somalia is about where the US was in 1925.

You are talking about admissions for highly specialized schools, which exists in America as well. This article is concerning regular public universities.
You didn't state the use case initially. The context of the discussion is evaluating the value of the approach. What I'm saying is that you can't make that evaluation without stating the use case. Obviously one can think up a scenario where JsonLogic can be useful - that doesn't mean anything.

> Interoperability is the main reason. We need this data and the evaluation matrix to be portable across different "credential wallets" as part of a standard model for matrix evaluation of Verifiable Credentials (see also https://www.w3.org/TR/vc-data-model/).

Representing verification logic in the schema flawed. Just because the W3C publishes a spec doesn't make it good.

So I guess one of the few valid use cases for JsonLogic (or similar) is if your company makes a bad technical decision and you're forced to implement something?

The only way would be to have arbitrary precision integers by default and thus no overflows ever. (IIRC smalltalk was something like that, but it was long time ago since I used it, so I'm not sure)
Programmers are already familiar with the surface syntax, including gotchas like only having doubles.

Also, the logic can be embedded in an already-existing JSON file.

This is useful if you occasionally need to look at the file, but usually you don't, so it's not worth putting any more effort into nice tooling.

I think it's better to not contribute to an environment of hatred towards large groups of people. Is the question potentially interesting? Sure, I suppose. But there's a huge difference between idly thinking about something and telling everybody else that they should as well. The latter has consequences, and you can't just ignore them.

My wife once taught a kid whose father kept brusquely "correcting" them any time they they used saw, as in the simple past tense of to see, correctly. The father insisted on seen, and not in a "that's how we talk here" way, but in a "that's how you talk period" way. I'm sure that wasn't the only way he was harming (or trying to harm, anyway) his kid's prospects.

Of course they were poor, too. :-(

> Speaking of which, Trump's "travel ban" (that wasn't a travel ban) was the single action taken after the virus was already spreading uncontrolled in NY, Washington State, and Europe. It did nothing to restrict US citizens traveling to and from the affected areas unrestrained, which thousands continued to do, even if we believed it would be remotely effective at that point

I'm not defending Trump. I'm pointing out media hypocrisy. What did they do? Call the travel ban racist. Their behaviour has been very partisan, often at the expense of the truth. Exhibit A: the lab leak theory in the OP.
There are a million ways to try to deny the forbidden conclusion, but none of them has withstood empirical scrutiny. Twin studies, adoption studies, etc. The only hypothesis that fits the data is that different races have different distributions of intelligence.

There's no reason this should be surprising. Races differ in height, musculature, bone structure, etc. We know that smart people tend to have smart kids and dumb people tend to have dumb kids. Why would intelligence be exempt from variation across races when no other complex heritable trait is?
Speaking of Wordpress: This would be an amazing tool for someone managing a lot of Wordpress sites -- I can picture it allowing for global changes across multiple sites, bulk content uploads, etc.

Almost certainly not your primary use case, but probably a quick way to gain market penetration if you or someone in the community built an integration for that purpose.
I'm talking about situations like search, where you hold the entire index in ram. Total # of machines = size of index / indexserver ram. Usually the apps that run on these have, say, 96 cores and they're using about 80, and the idle time is mostly instructions waiting for memory fetches.

Typically that index fronts a disk repository which wouldn't fit in RAM, although over time, what fit in RAM, what fit in disk, what lived in RAM, what got cached in RAM, etc, have changed over time.

BTW, I'm probably of the same generation as you and the single most important lesson I ever learned for computing performance was "add more RAM"; in the days when I first started using Linux with 4MB of RAM, it wasn't enough to do X11, g++ and emacs all at the same time without swapping, so I spent my hard-earned money to max out the RAM, at which point it didn't swap and I could actually do software development quickly.
Refuse to choose by Barbara Sher is an interesting book about this phenomenon. It talks about different types of “Scanners”, some switch topics every few years, others weeks, days or even minutes. The books main advice is to not fight these behaviours but instead figure out a way to use them to your advantage.
