You're not supposed to understand "the opposing argument", because it's fake. The real goal of this change is to increase the gap between kids whose family situation will give them an opportunity to learn actual math before college, and those whose family situation will keep them permanently locked out of college. This will ensure that the demographics of the next generation are even more skewed toward social instability and opportunities to replace "the current system".

It would be great to hear "this is why this thing didn't come from the lab: these are the strains under research, it doesn't match what was found. These are the security measures we have in place, here's all the audit data. WHO, please validate."

That would be helpful. Not this "yeah, we have this lab in the same area, why are you asking? It's fine. No you can't look, that's disrespectful."

This is fishy. Even if this pathogen specifically, didn't come from the lab, someone somewhere messed up(or is doing something messed up right now) and don't want people poking around.
I agree they leave a lot to be desired, but they're both at least perceived as somewhat reliable and trustworthy - factcheck is used by Facebook for example. I'm sure lots of people have pointed to those sites as proof, unfortunately.
What are you parents in California looking to do for education nowadays?
Absolutely, a high speed ferry could have great throughput; it seems like a great choice if they're going to put a few dozen or more people onto one of these rockets.
One of the smartest guys I ever met, a professional magician by trade, learned calculus in the sixth grade.

In an age where advanced applied math skills are the shortest path to six and potentially seven-figure salaries, by all means dumb down California further than it's already been dumbed down, but I have to ask questions about where all that 10 to 14% state income tax money is going besides those ridiculous six-figure pensions for retired state employees.
I'm going to be controversial and say this has a marginal impact on educational outcomes. Probably skewed towards better as I'm assuming they've done their homework.

Look, kids who love math and nerd out in their spare time will still be tearing into calc in uni.

Those who don't will still pick up enough to hit the trades or JOB.

The kids who don't need advanced maths might actually get more out of what they do learn as it's delivered at a higher age.

Ok who knows maybe it has marginally lower outcomes over all. No one knows and the people in this thread decrying the end of exceptionalism are deluding themselves into thinking life outcomes are extremely sensitive to high school educational content. I don't think that's verifiable.

Getting people to school and keeping them from dropping out is likely a better first order optimization to overall outcomes. Kids are still going to get their calcs in uni and the universities will still be pumping out overly-educated overly-indebted young adults...

Wikipedia has a list of all the biosafety level 4 facilities.

The answer is around 30 active sites that deal with threats as serious as the Wuhan facility. Of those, less than half work on viruses, and even fewer do GOF work.

So not that many.

Why not stream the classes so that the intelligent fast learners learn algebra early and the slow learners pick it up towards the end of their time at school if at all? That way nobody is inconvenienced by disruption from those that don't get it, and those that don't get it don't get hurt feelings.
It has been around in industry for at least twenty years. Facebook is a bit unusual in using it as an actual job title, but it's by no means new.

If you want a fuller explanation, I'll just ramble about some random bits. Replit will let you create an account, with which you can create "repls": on their own, they are the "disk images" I mentioned; they store files and a few other bits on Replit's servers. You can open this repl if you own it, and edit it in the in-browser (Monaco-based) IDE. Because you own it, Replit will spin up a VM on its servers to handle your session. Your changes sync in real-time with the permanent files in the repl, as well as the live (and ephemeral) filesystem of the VM. All of this happens over the WebSocket-based protocol I mentioned. What you're seeing with this post's link is a repl owned by someone else; in such a case, you see the "Spotlight View", which is read-only. You can fork it to create your own copy of the repl, which you can edit. The list of files is a read-only view of the repl's files. When you run it, it'll spin up a VM similarly to how it does for you with the IDE. The VM I've been mentioning is a restricted Docker container running on some GCP container instances, managed by Replit. It runs Ubuntu 20.04 LTS (I think) if that's what you want to know. The desktop you see when you run this post's link is a VNC connection to a Fluxbox desktop on the VM. The console is sent from the VM to your browser (again, all of this is over that WebSocket protocol) and rendered by xterm.js. Overall it's a bit of a messy system, and there's quite a few other things not mentioned; they'll occasionally talk about this on the blog (https://blog.replit.com/). If you want something more specific explaining, I'll probably do a better job at that.
Signal doesn't have the benefit of resources that telegram does. Also, they have to build their platform out "correctly" the first time, which makes life much harder.

That's how I learned a lot of things. My dad would mention what atoms are and that kind of thing, and I'd read about them in magazines, so them when it came to school it wasn't so big a leap to add a bit of rigour.
N.b. the liberal arts education, trivium, and quadrivium are experiencing a bit of a (modernized) revival, especially in Catholic circles (some examples [0]). Education traditionally was concerned with the formation of human beings as free, rational beings. (The word "liberal" in "liberal arts" refers to freedom, in the authentic sense, and it is contrasted with the "servile arts"). In this sense, modern education isn't education. It's job training.

I'm not quite sure what this Catherine project is proposing. What you don't want is just some random selection of topics with no regard for unifying principles, intrinsic importance, or the fundamental concerns of human existence. Even the so-called Great Books[1] curricula, themselves often plagued by a bias toward anglocentrism, have been known to degenerate into "selected topics" with no unifying principle. In so-called classical education, everything that is taught is taught in a cohesive fashion, at least ideally. Modern education is Kafkaesque in this regard: things happen, you're told to do some things here, learn some things there, but there is no cogent overarching whole into which everything fits. The goal isn't to educate as much as it is to equip students with an assortment of skills thought to be economically valuable here and now. Of course, being able to provide economic value is important, but that is secondary to becoming properly formed. A technically savvy savage is still a savage, but even here, his savvy is bound to be superficial. Ironically, someone who is properly formed in a real education is more deeply equipped and free to provide economic value.

All education systems presuppose some vision of man. The modern education's view of man, as an economic actor and a cog in a machine, is a bleak, stunted view of the human person and ultimately one that is dehumanizing.

Like many other things California (and SF in particular) is doing, this is cruelty disguised as compassion.

Let's take away the opportunities to get ahead early, because it may disrupt some egalitarian principles that are totally absent in the real world. As someone who majored in mathematics and was involved in educating K-12 students for many years, I find this to be completely ignorant of the reality behind school districts like those in the Bay Area, where affluent kids take Russian math after school to compensate for the inadequacies in their school's mathematics curriculum.

This is basically what we're dealing with here in California: https://equitablemath.org/wp-content/uploads/sites/2/2020/11...

"The framework for deconstructing racism in mathematics offers essential characteristics of antiracist math educators and critical approaches to dismantling white supremacy in math classrooms by making visible the toxic characteristics of white supremacy culture with respect to math."

On page 8, the authors claim that one way white supremacy manifests itself is when "students are required to show their work in standardized, prescribed ways". This is literally the definition of mathematical notation, and the use of standardized notation is fundamental to being able to communicate with other mathematicians.
I’m Danish and not at all interested in the politics of it, but there can be a case for teaching algebra late. We do it in Denmark, because it’s the subject children have the hardest time learning, and having too many of them fail too early kills their interest in math. We still teach algebra in grade 7-9, but we’ve gone through the social experiments of teaching it at different ages, and have lost entire generations because it was taught too soon.

I don’t think social justice or equality should play a part of the argument, but it’s always hard to tell where the legislation ends and the propaganda begins these days, and I’m honestly no interested enough to read the 800 page document this article is about.

I will say, however, that I think we’re going to have problems teaching math until we reform the school system to be suited for the modern world instead of the early 1900’s “assembly line” society. It makes no sense to place children in classes based on their age, and certainly not for all subjects.

The result is always going to be that both slow and brilliant students get fucked over, in a myriad of ways, especially if they are a mix of good and bad at different subjects.

Why exactly is it that you aren’t taught courses like math, or history or language according to your ability instead of your age?

> You shouldn't optimize for the average student; you should stratify instruction so students of different levels are pushed to their limits and beyond.

While I personally agree with your point, I think your statement makes the case for the folks who developed this policy.

The “problem” that these policymakers see is that students, when stratified, are not stratified across certain groups in a proportion that is similar to the population.

For folks who focus on equality of outcome, this is a problem.

For folks who focus on equality of opportunity, it is not a problem.
Similar incident: in 1985, political opposition in People's Republic of Poland "hijacked" TV by broadcasting in sync with the actual TV signal. This allowed them to superimpose things on top of the image (within some range around their transmitter), which they used to broadcast political messages.

Differences: not complete replacement, but superposition; "attacked" signal was the final signal to consumers; the hackers were caught (by standard police methods).

Gifted programs do very little or nothing as far as most studies can tell. Any gains in scores are very small, and they don’t appear to make any meaningful difference in student engagement or motivation.

These programs are relatively expensive, and there’s a strong argument the gifted programs should be overhauled, or that the money could be better spent elsewhere.

Cynic warning. Why wouldn't they instead choose to work with something they enjoy doing? Is that just a euphemism for some people being so bad at what they do in general that no one would pay them for doing the things they enjoy, while they just pass the bar in some things (which they dislike), just enough for them to get paid? Because that would explain it.

All good points. I was using GP’s $40/wk for the sake of argument, and “savings account” more as a figure of speech than to literally refer to a savings account (for the reasons you pointed out). I do contend that, for people who have such a small amount available for food every week, saving any amount of money (let alone $1k/mo) is extremely difficult. Life is a never ending barrage of unexpected financial hits, especially when you’re already living frugally.
I would say a strong counter to your argument is that Covid highlighted the need for much better STEM education, because of how painfully obvious it was that so many do not understand "the science". That's in quotes because that's the phrase that was bandied about so often.
> It requires 1 person (the president) to agree to build emergency hospitals, or at worst 51% of 535 people in congress.

At worst, it takes 60% of the Senate (because cloture), 218/435 in the House, plus the President to pass the law to do it federally, and then someone invokes the judiciary via lawsuits over federal authorities (“building hospitals is not an enumerated power”).
How do you think Signal could be funded in the long run? It is clear that optional donation doesn't work in actually getting to a non loss state, let alone being a company who could hire top engineers and invest in some innovation.
Ideally yes. But looking at the images I am not sure they did that. Unless there is some Aston Martin Valkyrie level of hiding underside aero...
I didn't say boards are capricious. They just have a clear motive: more money, now. This should not be a surprise to funded CEOs. Don't let your happiness depend on making a board happy, if that's not what you bring to the table.

If you're the best person to achieve more money, now you stay. But if you cease to be the best person to achieve more money, now, you are susceptible to replacement.

Of course, there are transaction costs that might make a particular pivot too expensive. McDonalds isn't going to pivot to Elon Musk, even if Elon Musk is objectively the world's best CEO. In that case, the current CEO may still the "best" guide to more money, now, all things considered.

But no CEO can adopt a long term position inconsistent with their Board's two goals (more, now) without risking replacement.

I can't think of a worse group of people to try and make do sales.

Good sales requires cultivating the right environment for good sales people. That means you need good pipeline. Sales people are blood-thirsty mercenaries who go wherever the most pipeline is so that they can maximize their personal income. They're short-term minded people who only care about results over the next quarter.

Ph.Ds are inherently delayed-gratification types of people. Salespeople are thrill-seekers (aka, always crash the sales department's parties if you want to have the best time).

China built a 1000 bed covid hospital in 10 days and staffed it with army nurses.

Compare this to requiring 330 million people to continually agree and coordinate basic pandemic behavior like masks and vaccines.

Costs are largely irrelevant. Perhaps 100 million for such a hospital. This is 0.0001% of the 6+ trillion the government has spent on other covid actions.

> ...is more concerned with providing child care rather than instruction.

Which could actually be a reasonable design for school.

If public schools can't teach advanced topics, they could still handle the basics, provide childcare, and help to socialize kids.

And then tutors (backed by a voucher system), parents, and the internet can do the teaching of advanced topics.
Why Foxes Are Better Forecasters Than Hedgehogs – Philip Tetlock [video]
The structure you describe is 1) legal and 2) typical.

Preferred shares cost more, but for that extra money they come with preference. What is preference? It can vary, but the term that matters most is that they get to earn their money first. A 1X Preferred share (very generous) will be paid their investment back before anyone else sees a dime. Often shares are not 1X, they can be 2X or 3X, which means they will get more than they put in before anyone else sees a dime. There are more variations, but this is what matters in the story you’re telling.

Common shares, which is what employees receive, are much, much cheaper (the strike price will often be pennies on the dollar compare to preferred shares that investors receive). However they simply convert to common stock when they’re exercised, with no special treatment.

How does anyone make money then? The answer has to do with liquidity events that are large enough that everyone is getting their money. If money is limited, the investors get it first.

Iterators can be invalidated (e.g. after a rehash). The requirement is rather that the address of the value itself must not change (so that pointers will remain valid).
