> It's not like the kids get one teacher their whole life, every kid going through the public school system will have dozens of teachers and the affect of any single good or bad teacher averages out.

"averages out" - No, it may not.

I had the same teacher for 4th and 6th grade in elementary school. I thought she was great. A friend of mine _changed schools_ so she wouldn't have the teacher again, because the teacher had been verbally abusive to her. I never saw it, but it was a big deal to her.

A year later, I had a teacher who would _publicly_ ridicule and harass me. Sure, I only had to deal with that for one class and homeroom everyday for TEN MONTHS, no big deal, right?

My other teachers weren't like that. But one is enough.

My anecdotal experience as a parent is that there are far more teachers like that now. (The students are often worse, too, which may be one factor.) To write off abuse from a) persons in authority and b) government employees as "oh the kids will get over it" isn't just wrong, it's demeaning.
So I run a remote-first company and our team is all over the globe. We had some people (including me) who had this issue at one point.

I solved it by establishing two expectations:

1) No one is expected to be on Slack outside of their work hours. Full stop, pretty much.

2) Everyone must provide their personal mobile number to the company. They're all stored in an "emergency directory" (it's just a Google Doc). If there's an urgent emergency which can't wait until someone starts their next workday, you are allowed to call this number to reach them.

In five years there's been one call through that emergency system, I think it was a big customer getting hacked.

There have been many times where people just routed around the issue, like, "Oh, XYZ won't be available for the next 12 hours, I will talk to ABC instead and tell the stakeholder that I'll be able to get the expert engaged tomorrow" and it all worked out fine. Never been a big deal from what I've seen.

We lost half our revenue in a very short period of time during Covid - it didn't trigger a call. Why should it have? Very bad news, but learning about it at 10pm wasn't going to improve anything. People all got a good night's sleep and then woke up and saw the terrible news in the morning, probably for the best because they were refreshed and relatively prepared to deal with it.

Could you argue we're overall less responsive as a company because of this? Maybe but I don't think so, we haven't had customer complaints which would point to this. On the contrary we get customer feedback that our people thoroughly attentive to their needs. (Even with our customers we are clear up front about everyone's availability hours.) I do know that nobody is an anxiety zombie, and our people seem to be quite good at making rational and clear-headed decisions all the time, our company culture felt more panic-driven and knee-jerk before I instituted these rules. I'm pretty sure that allowing people to be totally unplugged for 16 hours a day if they want makes them better performers during the 8 when they're on the clock.
Yes the PPU is more complex than the CPU, but the audio emulation was more difficult than the PPU for me. Noticed the audio is a TODO for this emulator.
Except they have much more flexibility, up to individualization, in terms of curriculum content and pacing, teachers from potentially more varied backgrounds/main jobs besides teaching, and the ability to eject unruly and problematic kids that impact other kids’ abilities to focus and learn?
We were forced to homeschool our child due to Pandemic, and later, from desire for him to actually learn. It was eye opening! Schools are chaotic, and one of the biggest take aways for the child is conformity. In fact, I believe the entire institution of age based grades started in the militaristic state of Prussia. From the point of view of a state that needs soldiers, having standards and consistency is important. Individualism, and creativity are not very useful in a marching formation. And questioning authority, is equally frowned upon.

Nobody solves all their problems. But they can prioritize, make a plan, and knock them down one at a time. Success isn't instant, either.

NYC is nowhere near the population density of many other global cities, even nice ones like Seoul [0] (sorry for the mediocre link). Anecdotally, as an NYC resident I am astounded by the number of empty lots in Manhattan and buildings with three or fewer stories. I don’t think the issue is land capacity.

School is local in the US, so there’s no point in generalizing when discussing things like teacher salary.

That aside, a fantastic highly trained teacher with 30 students, isn’t likely to outperform a mediocre teacher devoting their full time to 1 or 2.

I wasn’t homeschooled myself but I did help my homeschooled younger (by 20 years) sister with math. If I had the time to devote 30 hours a week or so I’m fairly confident I could outperform even the best teacher teaching my own kids—-assuming they had 20+ full time students.
Do you think humans have infinite capacity to store their trains of thought?

We invented writing stuff down for a reason. Mathematical notation is precisely a tool for enabling humans to extend their train of thought beyond their immediate 'prompt context length'.

Even with finite working memory, humans are generally considered capable of exhibiting intelligence.
What did you all think was happening? Parents chose to hold their children back in subject areas they were weak in? Of course we delegate teaching certain topics to professionals.

The thing about those professionals, they know their continued employment is based on the merit of their work. You can fire your children's teacher(s) and hire better ones.

It stops and demands help. While car automation leans on GPS/nav, it won't blindly follow it -- similar to (almost all) humans.

It’s illegal, in many places, to sell your vote. Extending that example to a general principle — if you have any decision making power/responsibility over others, then allowing it to be subverted (for pecuniary or other benefit) is a dereliction of fiduciary responsibility.

If you are only selling consequences on yourself (we can debate the legality of that, and protections necessary against exploitation) that’s a different scale of potential harm compared to selling away the power concomitant with your duties.

By that logic, it might be possible (if the potency of behavioral advertising can be established) to forbid people from holding decision making responsibilities (including voting) if they wish to sell away their decision making power for benefits.

At the extreme, imagine board members or government heads deciding a question of enormous importance, and their decision making getting hacked by personal behavioral targeting. If that sounds too fantastical, imagine a popular streaming service promoting an emotionally charged war drama (for Washington DC subscribers) when Congress is in session discussing geopolitics questions. Or more precise targeting analogues — aiming at key decision makers, or their friends/family. I doubt shareholders / stakeholders would be okay with that.

Learning how to deal with adversity and dumb people was school's greatest gift. The world is full of both.
right, it is almost always cheaper to destroy something than it is to build it. there is some beauty to this principle, in a cosmic sense, but this particular stunt doesn't impress me either.
Historically schools were usually a way to do one of two things: provide a strong education (mostly in the humanities) to the upper class, and teach basic literary skills so that kids could read religious scriptures and then later, post Enlightenment, adequately participate in government and society (including basic arithmetic and non-religious literary skills). The first public schools in New England were motivated by the pre-Enlightenment attitude and public schools became more widespread with the post-Enlightenment attitude.

The idea of public schools as a way to enforce national unity (~WW1 when it became a priority in the US to de-italicize ethnic identities and loyalties) and teach kids skills that would set them up for nationally important jobs like those in science and technology (Cold War) was a much later phenomenon.
If we're at LR2, and each level is effectively unaware of the levels above it, how do we know what LR3/4/5/6/7/8/9 are or might be?

Or do you mean that a civilization at a particular level will always be unaware of civilizations above? That doesn't seem to make sense either; I see no reason why a LR4 civ couldn't have knowledge of a LR5 civ, for example.
This seems like those conservative talking points "I saw a homeless child on my drive to work today. Why are we sending money to Ukraine".

> There's a history of oil companies buying patents to inventions that could increase gas mileage etc.

Oh, that one. That theory was all the rage in the 1970s. Oil companies buying patents for 100 mpg carburetors and then quashing them. I asked my dad (23 years in Air Force) about that. He had a big belly laugh. He said one of the biggest logistical problems the military had was fuel consumption. Destroying the Axis fuel supply was a major component of the Allied victory.

There's no way in hell that the military would not use a suppressed patent that doubled mpg. (The military bulldozed aside the airplane patents in WW1.)

This is a “tell me you don’t homeschool without telling me you don’t homeschool”

No homeschooling family I ever met has set hours, and most spend far less time than that daily. Schoolwork takes a lot less time when you cut out the crowd control, distractions, “pledging allegiance” and other nonsense

They did an interview with the guys from NYT's Hard Fork (https://podcasts.apple.com/us/podcast/hard-fork/id1528594034...).

When asked what their act of protest was against, they said "cars in general." They're very anti-car and, although they acknowledge that self-driving cars will be much safer in the long term and could transform a world full of wasteful single-car ownership, they are adamant that cars shouldn't exist.

Yes, they're in their 20s and enjoy riding their bikes in San Francisco.

I hope your children don't get "exposed to this reality" in school, as you put it.

The sorts of harrassment that school bullies inflict on their victims is, to put it simply, not tolerated anywhere else. Why should it be tolerated when it happens in school, where the victims have no choice but to attend every day?
I'm really curious to go back to Show HN posts and see if there are any interesting stories associated with the project. It would be fascinating to see if some of the stories didn't hold up but the projects benefitted from them. I bet it happens even here on HN.
> Show me a poor school district with a public school that looks like this: https://www.youtube.com/watch?v=Xm4dy25VmCw

Carmel HS in Indiana is funded at $9.6k/pupil [0]. My urban school district (DC Public Schools) spent ~$22k/pupil [1].

> It's also absurd on its face to think money has no effect on the quality of instruction, the market works pretty well for everything else, but teachers don't respond to incentives

Schooling is not anywhere close to a market and public schools are not private enterprises. As I've shown above, my poor performing school district was much, much better funded than the Tiktok you linked - much of the problem is on how that many is spent and what is happening within the schools - inequality in funding is just not sufficient to explain gaps in performance. [2]

The paper underlying your second link (https://www.nber.org/papers/w22011) seems strong and potentially causal, I will read it with interest.

> However, we don't do nearly enough to correct for the affects of poverty. Someone growing up in poverty needs a lot more education help than someone growing up in a middle class or upper class family (on average). Also, it's way, way more stressful to teach kids who are growing up in poverty than otherwise, but the salaries do not account for this. So the teachers who work at the poor schools are often working at their last choice school, even if the school nominally has the same level of funding. They're the teachers who couldn't get hired elsewhere, or were hired simply because the last teacher quit out of frustration (I don't want to begrudge teachers at poor schools, there's a lot who are very good at their jobs and who love their students, but this isn't enough to overcome systemic differences).

This part I largely do agree with, I think salaries do try to account for this to some degree (public teachers where I lived made 6 figures often if they taught in schools like these) but not to a significant enough degree (we should be paying close to software engineer salaries IMO).

The goal of lowering to binary at 0.1 million lines/sec isn't very ambitious. Virgil bootstraps its 59,000 line compiler in 400 milliseconds, which is over that number, and it does whole program reachability and optimization.

On the other hand, the 10 million lines/sec parsing is probably not achievable. Thats 400MB/s. The fastest JavaScript parser I know of, V8's, is on the order of 60-80MB/s. Virgil's is about 45MB/s. Maybe if you are parsing Lisp you can get to 200MB/s, but no curly-braced language with actual syntax is going to parse that fast.

And you don't have to parse 10X faster than semantic analysis. In my experience, semantic analysis is only about 2X as expensive as parsing, so that 1 million line/sec goal for semantic analysis is easily achievable. (Virgil is at about 800KLoc/sec).

Keep in mind the above is all just one core. 10 and 20 core CPUs are becoming widespread, and these two phases parallelize nicely. Just don't do C's stupid O(n^2) header madness and Carbon will compile plenty fast.
Economic effects of a prolonged deterioration in the general health of the Spain [pdf]
From recent headlines, it sounds like people are protesting the fact their city is being used as an alpha testing site and causing a nuisance.

I don't think its necessarily in protest of the technology in general, but the irresponsible way these things are let loose on the road without a person there to get it out of the way when it gridlocks.

Its an issue that can be solved by spending relatively little money on a test driver's salary that they're purposefully avoiding to save money and avoid responsibility.

Driverless cars will eventually be safer and more efficient than human drivers

That'll happen only when we have solved the general intelligence problem. Driving on roads is a cooperative process, it requires a theory of mind, and many people are sick of making allowances for experimental technology that is inherently incapable of performing as intended. It's the equivalence of goldmaking alchemists.

Meanwhile there's us motorcyclists - I trust robotaxis to even estimate distances as much as I trust drunk drivers or teenagers on their second driving lessons.

Sure. Here's a couple of functions to iterate over an array of "Ball" objects, as you might do in a Breakout-style game that has a multi-ball powerup. I didn't do anything to make it particularly 6502-amenable; it's how I'd write it for a modern machine, probably. Even compiled with -O2: as expected, the code is slow and enormous - a single addition compiles to something like 30 instructions.

False positive punishment is more common than one would think. It's fine to ban accounts for alleged fraudulent activity. The question is why isn't there a path for recourse when you're only a false positive?
