"Generics" is not why Rust compiles slowly. Rust had certain design decisions and implementation details that impact compile times significantly. Do not misrepresent them and pretend that the Rust developers are incompetent or mal

I am not too familiar with D, but it seems that D's borrowing system is somewhat different than Rust's, given that it is not the focus of how D is implemented and used. This means different design tradeoffs. There are appropriate

Internal use of unsafe requires securing the safe code at the module boundary. However, the design of unsafe still greatly reduces the burden of memory safety, both when it is and isn't used directly. The specific semantics of Rust asi

Your point about compile times is very dismissive and wrong, but I agree aside from that. It's worth noting that the Rust team explicitly tracks, monitors and limits regressions in, and actively optimizes for compile times, and Rust co

If any language would've had this bug, why is Rust being singled out? If the software was written in Go, would the bug get the same attention? No programming language should get flak for a bug that is not the fault of the programming l

(I haven't presently read Wolf's essay on account of it being paywalled. However, I think I get the gist of it, and Scanlon's view too, from the abstract and some commentary.) I see good points from both Wolf and Scanlon, but

While the US education system is plenty bad, I expect that a substantial number of people who can't/don't cook are not held back due to illiteracy. To be fair, this thread seems to be discussing recipes and dishes, but even &

Moreover, changing one's habits to cooking requires effort upfront, and its benefits may not be apparent (at least in the start).

I think this is a good example of how lying can affect one's autonomy (though I don't remotely hold that as an absolute principle). In the ideal exercise of love, I agree with your claim. I don't think it's dismantled in

I find it very hard to judge whether I'm fulfilling that part of the guidelines. I only have a few submissions, and I think I'm good there, but I'm more conflicted when it comes to upvoting or engaging in other people's

The notions of "blame", "excuse", and "forgiveness" are strange to me now. I want to say that understanding is key, and everything else follows from understanding. If I understand a person's action, I shou

The "never had to work a day in his life" claim is wrong, though I agree his experience seems insufficient for the position of mayor.

When I brought up grade inflation, I meant it as a factor of a different kind than { COVID, phones, generative AI, ... }. Grade inflation is the reason why the decline is deceptive. > > What aside from grade inflation explains why tho

I can't honestly call myself "anti-woke", nor can I honestly call myself "woke". What a pain. Harping on about either one makes for a dull comment. If anything, I'd probably be considered "woke" by id

In fairness, I think reading abstracts is a good way to 1) quickly gain information and 2) figure out if the paper is worth the time to read. Especially for paywalled papers, and when I'm trying to get a broad sense of different ideas,

Grade inflation seems to be the main long-term culprit. Lowered standards mean that any student that isn't incentivized for some other reason to learn math simply won't learn. I'm less enamored with the other explanations, su

by vacuity 11mo ago
When the education policy is less about "how do we teach math" and moreso grade inflation, I don't think it's strange.

Standardized testing isn't remotely perfect, but I think I have grounds to say that it is far better than many alternatives. In this case, standardized testing would've caught the problem before admissions.

As someone else mentioned somewhere in this thread, what about public schooling prevents students from learning by themselves? In my experience, the best students I know generally didn't become so due to public or private schooling, bu

The sad thing is that I saw that standardized tests were being blamed based on a certain ideology, when the proponents of the ideology should've realized that their own goals are better served by using standardized tests. It shouldn&#x

Based on what GP said, it isn't clear that the implementation of "allowing advanced students to learn advanced topics" is successful either. It seems like the current gifted/non-gifted system isn't working.

Alternatively, maybe some of the rejected students could be admitted. I don't know that any college has an excellent admissions process that reliably identifies talent (or the lack thereof).

It's not just about pride. Companies, artistic productions, projects of any kind...they require vision and focus. When the people in charge change, maintaining these becomes a challenge.

Percentages and arithmetic in daily life, programming, financial bookkeeping...to be fair, the math I use often is pretty basic, but even so, the report from UCSD seems to be saying that a significant fraction of the remedial math students

And in a classic stroke of Gell-Mann amnesia, if you're questioning what you just heard, how much should you trust what you were hearing five minutes ago?

I agree that learning is what is important, but I wouldn't assume that GP did not make an effort to learn. Learning an entire field is difficult, and small hints may be all that's needed to draw upon one's learning.

To me, a big factor that I subconsciously evaluate on is the "fakeness" of the appearance itself. Instances where plastic surgery results in the uncanny valley of "should be good but looks too perfect or messes up a critical
