(1) Most countries do not actually have a military. Instead, most countries outsource their security to the US (most common), to Russia (like Belarus), or to China (like North Korea, partially). Iran is unusual in that they're going it largely alone. They're also unusual in that they actually appear to be winning. And if Iran does manage to drive the US out of not just Afghanistan and Iraq, but the entire Middle East, they'll have unfortunately undermined the idea that America can or will provide any security guarantees at all.

Why I'm Skeptical About Efforts to Revolutionize Schooling
5 beliefs, in the piece's order there

Gamified learning is a bit like wrapping medicine in candy. Yes, it may help some students swallow some instruction they otherwise find bitter, but in practice it’s easy to pull off the candy, consume it, and throw the medicine away.

Their words
General problem solving abilities are neither learned nor taught. While some problem-solving methods have broader applicability than others (such as the scientific process of hypothesis testing), students learn these methods better when they’re explicitly taught rather than simply giving students projects and hoping they’ll reinvent them on their own.

I still meet people convinced that AI coding tools will soon reach a point where code quality, design, and even architecture are "solved". So I ran a small ad-hoc experiment. I’ve been working on a CLI tool and let agents plan and implement a first functionally correct version. I provided strict instructions around testing strategy, workflows, and implementation constraints. But I deliberately removed the @codescene MCP and the safeguards I normally rely on. Unsurprisingly, the resulting code suffered from a ton of problems. It would have been a shaky foundation to continue building on. How s… MCP Related

I was thinking about this prediction that we were going to see a lot more CPU bugs, danluu.com/cpu-bugs/, as yet another Intel CPU bug story is on the front page of HN. At the time, Intel threw quality under the bus in the name of velocity. I've seen this happen quite a few times now, sometimes with the stated intention of improving quality later. I'm sure it's ever happened, but I don't think I've ever seen a company do this and then ship very high quality products later. Related

Why Rust is different, with Alice Ryhl
5 beliefs, in the piece's order there
Their words
I think this is kind of leads to another way that Rust really helps with reliability, which is that if you're refactoring, I think Rust is really good at telling you all the places you need to update. I've done this sometimes where I would refactor something. I change the code. I change the return type or whatever it is, and then I just fix the compiler errors and until the compiler stops shouting. And then once I've done that, I've updated every place I need to update.

documentation
Their words
Now the thing is you can of course write examples in your documentation and Rust makes all examples into tests. This means that if you change the underlying code now your test fails. And so this means that you can't even you can't forget to update your examples in your documentation.

TypeScript
Their words
But okay, so to begin with, I think when it comes to TypeScript, Rust fits in as the backend language. That's where I would put it. I wouldn't use it in the front end. I think it's a pretty good fit for backends, API servers.

I think to have a language that feels this way you have to have a type system. That's where it all starts.

Why Rust is different, with Alice Ryhl youtube.com
Their words
I think part of what I liked about Rust is this feeling that as you write the code when it compiles it works. I mean this has to be in quotes right because obviously it's possible that there are bugs but this is something a lot of people say about Rust and there's a reason people say it even though it's not necessarily literally true.

What is a korrent?
A korrent is a belief a person has stated in their own words: one
sentence stating the claim, backed by a quote and a source, kept at
korrents.com .
Under a name here, the quoted block is what they actually said.
The korrent beneath it is the claim those words support, in
korrents' wording — tap it to see the record, its source, and who
else holds it.
Nobody here wrote their own korrents. They are compiled from public
statements, and a person can change their mind, which is recorded too.

About the English under a post
Some people here publish in a language other than English. Where they
do, this site shows a machine translation beneath the post, in
this typeface — the site's own, not theirs.
The post itself is never changed, moved or hidden: what is set in the
serif above is exactly what the person published, and it is what to
quote them on. A translation can be wrong in ways that matter,
especially about tone.
Only the post's own words are translated. A quoted post, a linked
article and a belief on korrents.com
are left in their original language.
