Great list. You missed an important one: Being selected for admission to validate your worth.

The entire HS experience (in the US) is formulated around this validation. Simply being chosen is a reward in itself.
I think the title is clickbaity. As mentioned in the article there is more to University than just classes, there is the social aspect of campus life etc. So it's not like the Uni is getting obsolete because of online learning platforms.

That being said I think there is indeed a big potential to offer quality content at a reduce cost, and make knowledge accessible to more people, especially in countries where access to university is extremely costly, hence access to education not equitable.

Having social, human one to one interaction with professors like Deleuze, Grothendieck, who, in example, where both teaching in French Uni, is not quite the same as watching a video online. So I'd say Uni is the color dolby surround cinema experience, online learning is the black & white TV at home.
It's also quite a bitter taste and coffee-drinkers may have more flexible palates and diverse (generally more healthy) diets as a confounding factor.

>Who wants an app that you can’t do anything with when you download it?

Apple has accepted plenty of those into the App Store before. Maybe you can't expect every application on the App Store to work after downloading. I don't own a Tesla, so why should I expect the Tesla app to do anything for me?
That is a pretty fun architecture. I hope that opens the door to higher performance for more workloads than top500.

At least with the top500 benchmark, the bandwidth is not a problem, so long as you can do a large enough problem. Since it is a linear solve that spends all its time doing matmul (n^3 operations on n^2 data), so long as the problem is big enough, you can saturate the cores.
I first read about this several weeks ago. After they occurred they were called Race Riots, it seems lately it’s been called a massacre, I’m not sure what the difference between this and a pogrom is.

I don’t mean to detract from the story, but there’s a hidden nugget in how such a successful and thriving black enclave started in the first place. Having followed urbanism these thriving enclaves are precious.

There's an extremely old joke (like 100+ years old; I can't find the source atm) that goes something like: "US universities are the best high schools in the world". And it's true. It's not safe to assume that someone with only a high school education will be able to write well, do basic mathematics, etc. The high school grads who go on to teach themselves how to program are an extreme outlier.

The entire US education system needs an overhaul. You can't really fix our university system without making corresponding reforms in K-12.

A lot of it grounds out in trying to be overly egalitarian, realizing that doesn't work, and then hacking the system by introducing an honors/AP track. As a result, things are no longer egalitarian (the split between honors/AP and not-honors/AP happens freshman year or before). However, instead of having a gymnasium-like true high school liberal arts curriculum, we instead just moved some fairly boring college 101 courses into the last year or two high school. Which really isn't the right thing to do.

We should now make the split explicit. And then, instead of teaching mediocre university 101 courses to the honors ("gymnasium"-like) students, simply study the high school material but at a much deeper level in the "honors" track.

Then, the university system should split in a corresponding way, with non-honors students going to applied universities designed for them and honors students going to universities designed for them. NB: this split already de facto exists; there's a whole class of universities you can't get into without doing the honors/ap track in high school.

The ranking is calculated based on the Linpack benchmark. Being a parallel application, performance is not simply scaled to number of processors; the network interconnect is hugely important.

Now, although Linpack is a better evaluation metric for a supercomputer than simply totaling up # of processors and RAM size, it's still a very specific benchmark of questionable real-world utility; people like it because it gives you a score, and that score lets you measure dick-size, err, computing power. It also, if you're feeling unscrupulous, lets you build a big worthless Linpack-solving machine which generates a good score but isn't as good for real use (an uncharitable person might put Roadrunner https://en.wikipedia.org/wiki/Roadrunner_(supercomputer) in this category)

Not sure how slow it’s ARM processor is in actual use, but we know it’s far slower than Apple ARM CPUs.
It’s true that Apple has done two moves to different chips with success, but both times it was to a more capable and probably powerful processor. When moving to PPC they allowed to run 68k apps/code without too much penalty. When moving to x86, there was Rosetta[0], that made the entire existing library /almost/ work seamlessly. moving to ARM... this might not necessarily be true. Sure, you have Catalina but iOS apps on macOS says nothing about all existing apps for macOS. I have no idea of the amount of already existing apps and what would be the amount of work needed to move them to ARM. Very likely Apple did the math and it will be easier/there will be incentives for devs to move to that platform. They do have experience though.

The director's cut provided non-combat solutions to some of the boss fights. But at launch, yeah, those were a huge miss if you had optimized stealth or hacking skills.

AWS has made it into the top500 a few times in fact, though not that high on the list. I think the main issue would be reserving enough machines that have a high performance network between them, which is not a typical cloud need.

But the more interesting question for me is: on an embarrassingly parallel workload, how does Amazon’s full infrastructure compare to these top machines? I’d assume that Amazon keeps that a secret.
That reaches temperatures of 25,000C. AFAICT we don't have any materials that can withstand that, so that reactor remains theoretical rather than practical.
The word you're looking for is propellant. In chemical rockets, the fuel and propellant are the same thing (to be precise, the combustion byproducts of the former comprise the latter). In nuclear fusion and ion thrusters, they're different. In all cases, Newton's second law means that you are using up propellant to generate an equal and opposite reaction in the direction you want to go, and thus the amount of "going" (delta-v) you can do is limited.

> based on your ability to solve the largest dense linear solve you possibly can - something almost no real application does.

Sounds right.

I was going to say what about large-scale optimization problems? But I realized that most typically only require sparse linear solves.

Gradient descent does require the solution of dense Ax=b systems. But the most visible/popular application of large-scale gradient descent today, neural networks, typically use SGD which require no dense linear solves at all.
Gamedev in JS here, findings are very interesting. Memory management is really a pain with JS, the GC is giving me nightmares. Thanks for the article.
Forms suck, but if you actually make a form, it becomes clear that while you can do 90% of stuff declaratively, there's a leftover 10% that just has to be described imperatively, which requires something like JS. Modern forms actually give you a lot for free with pattern matching and whatnot. I could imagine it going a little further and adding properties for "dirty" or not, which right now you have to add using JS onblur listeners. Probably, the standards bodies could add in credit card field types and input masking to get things 99% of the way there. But there's still left over things like: your display name should default to being your personal name plus your family name, but also overridable. I don't see how you can create a declarative language for relationships like that without stumbling into a Turing tarpit.
I'm guessing that for each of your bullet points listed you needed some initial set of technical skills, and that you had those skills before even arriving at University (otherwise the first semesters would not have been wasted.)

It does not though? How does Rust proves that your implementation of a Peterson's lock algorithm[1] or Lamport's Bakery algorithm[2] is:

- Deadlock-free

- Live-lock free

- Free of data races

Second, how does Rust proves that you are correctly using the relaxed, acquire and release atomics so that your channel implementation is free of data races?

You can use Loom[3] but this is guarantee is certainly not provided by the compiler.

In short, Rust compiler only addresses memory issues by flat out preventing memory sharing. However, someone has to write those sharing/synchronizing data structures (Channels, Event Bus, Concurrent Hash-Table, ...) and those people have no tools that help them navigate the significant complexity of multithreading that go beyond memory and lifetime bugs.

Thanks, appreciate the feedback.

The good news is that I have been working on a new "Quick Start" tutorial for the Redux core docs [0], which is _exactly_ what you're describing there: an intro to Redux, for folks who have never used it before, which teaches RTK and the React-Redux hooks APIs as the default way to write Redux logic.

We also have an open issue to discuss reworking the RTK tutorial sequence [1], as there's agreement that the current RTK tutorials focus too much on migration, and the "Advanced" tutorial shouldn't include TS usage.

As I said in that issue thread, it's very hard to know how to split the onboarding flow and explanations between the Redux core docs and the RTK docs. RTK _does_ work best when you actually understand how plain Redux works and how to write Redux code "by hand", and can see the benefits and purpose of abstractions like `createSlice`. So, yeah, ideally everyone would go through the bottom-up Redux tutorial sequence at some point so they fully appreciate what RTK is doing for them.

On the other hand, it's true that RTK is a lot simpler to use, code-wise, and that there's less syntax to confuse people if they're getting started. Problem is, you still need to know concepts like "dispatching actions", "reducers", and "immutability", even if you're jumping straight into RTK.

So, bottom line: this new "Quick Start" tutorial covers exactly that "start Redux with RTK as the default" use case you're describing, and after that's done, my next task will be to rewrite the existing Redux core tutorial sequence. It'll still be a "bottom-up / how it all works by hand" approach, but updated to remove outdated content (like references to "Flux") and show simpler patterns (inline action type strings, "todos/todoAdded" instead of "ADD_TODO", single-file Redux "ducks" logic, etc).

I still don't have a good answer for how to handle the RTK tutorials, but I'm going to paste your feedback into that linked thread, and would appreciate any other suggestions you have in that regard.

Why do you believe that?

You're making the assumption that the problems involved with prolonged space travel are solvable with the time and resources we have here.

It could not be. It could be too expensive to colonize beyond the immediate area. If even the immediate area can be colonized.

There's also the assumption that there's going to be a good reason to make a non-returnable investment. Because, at some point, that's what it is. The speed of light is a limit we have not even come close to exceeding, much less approaching. And even if we do, and the people on the ship, time dilation, yadda, yadda. It does not matter. The people on Earth will still experience time normally. It taking the ship no time at all does not matter if it takes 1000 years on Earth. Or even 50 years. The return has to be phenomenal or the cost negligible.

> They become more healthful at the same cost? I find that highly unlikely. What you are doing is raising the cost of food across the board.

There is a real limit to how much food expenditure in general can increase. If prices had safe room to go up, they'd already be higher. You can see this by just looking at the price differences between poor area grocery stores and wealthy area grocery stores. There's a reason why poor people don't shop at Whole Foods, and it isn't because they don't like mochi ice cream and espresso bars. A very large percentage of people in the US actually don't have extra money to spend. On top of that, you're imagining that literally everything has and needs to have a bunch of sugar in it when that's just not true. What people will do first is switch to foods with less sugar, even if they don't like it as much, because the vast majority of grocery buyers are both extremely price sensitive and also adaptable.

> I could get behind subsidizing fresh meat and vegetables.

1. We do that already.

2. You're the only one suggesting that a tax on sugar can't go directly and completely to additional consumer-side price subsidization of fresh meat and vegetables. I think that would be great and fully inline with the goal of taxing sugar in the first place.
> I think I would say we project different aspects of ourselves into lower dimensions (thoughts and words) depending on the transformation function (context into which we are projecting ourselves).

Such a great way to articulate this. This is why I love HN.
That's fascinating. I know that AMD has been touting HBM as a faster memory subsystem for their GPUs, is that the same as HMB where it's stacked? Or are they just calling it something similar?
> I believe that (A) discovering what is considered normal in one’s community influences what one thinks, and (B) what one thinks is not disconnected from what one does.

It hasn't been considered "normal" to inflict violence on women for decades, so that's not really the context under discussion. The question is, under present circumstances in which domestic violence is a huge no-no, and everyone knows it's unacceptable, would the absence of comments about "scheming women" really prevent or reduce such violence?

Frankly, that's a tough sell.

> We can distinguish between these two cases because adopted twins and siblings have highly correlated genetic factors and weakly correlated environmental factors.

We can't, and the papers I cite give a highly coherent explanation for this, a phenomena called cultural filtering.

Like I said, I suggest you go and actually read recent papers instead of relying on a survey paper from fifteen years ago that relies on actual research older than many of the professors publishing this stuff today.

It's not worth having this conversation is you're unrolling to engage with modern research, and it'll just devolve into an ideological flamewar, which dang prefers us not to have. So again please read some modern research. Or don't, but don't claim this stuff is settled when your are a decade out of date.
>You get to see how the sausage is made in a developed country which is, by far, an outlier in its crime-rate.

I don't think that's actually true. I'll have to find the stats, but IIRC the number of raw crimes is comparable between Western Europe and the US, but in the US the crime is WAY deadlier due to all of the guns. Canada is somewhere in the middle.

“The new top system, Fugaku, turned in a High Performance Linpack (HPL) result of 415.5 petaflops, besting the now second-place Summit system by a factor of 2.8x. Fugaku, is powered by Fujitsu’s 48-core A64FX SoC, becoming the first number one system on the list to be powered by ARM processors. In single or further reduced precision, which are often used in machine learning and AI applications, Fugaku’s peak performance is over 1,000 petaflops (1 exaflops). The new system is installed at RIKEN Center for Computational Science (R-CCS) in Kobe, Japan.
I was sad and frustrated to hear about that story. Personally Nutty Putty freaked me out and I still wish I hadn't gone. The "viscerally uncomfortable" part far outweighed the interest factor.

I remember wondering why I was having to put such a huge amount of conscious effort into the process of turning around to head back to the cave entrance. Feeling stuck, clamped between huge slabs of rock is just not that fun to me. And while someone is saying "you can do it, you got this," describing to you how your limbs are arranged, so that you can even figure out how to move at all...

I had traveled there at age 18 with a few other teenagers. This factor also kind of blows my mind. Another one of the complicating issues was that we were going at the pace of the most experienced among us, who was very much a risk taker. Phew, major respect to spelunkers but I think I got off to the worst start possible, at the worst place possible for a guy like me. Every time I would hear about a tragedy in that cave it made me regret even the idea of cave exploring.
Other commenters saying it isn't used as a verb are wrong. They're correct that people never say "I open-source softwared my last project."

However you can definitely use "open-source" as a verb: "I open-sourced my last project." It's pretty common. And in this case "OSS" stands for "open-source", not "open-source software".

What's confusing you is that when we use the abbreviation "OSS" we're really intended people to read that as "open-source" even though the abbreviation technically means "open-source software". btw, you would never verbally spell out "OSS"—chiefly because it's the same number of syllables as "open-source".
