Americans mostly don’t even want to do the manual labor jobs which have always been available in the US, like residential construction or picking crops. And the oligarchs want to both reduce immigration and re-industrialize? It’s going to be comically unpopular.

I believe administrations like FDR or JFK would’ve tolerated none of this shit. Biden looked weak as hell. I like the guy and I support the democrats but you can’t take the high road indefinitely. I take your point though and I’m not happy about it either. But I would’ve preferred a bad boy Democrat administration over whatever the fuck this is…
You’re right of course. On the other hand this policy of strictly following established laws and precedents is in part what got us into this mess. Democrats could’ve been ruthless but they were meek. And now they have become almost entirely sidelined.
I read it and it is a good article. Thanks for sharing.
But yeah, stupid headline.

Not letting me reject trackers without paying is some real garbage…
It’s been continuously surprising to me how much hatred some C and C++ devs have for Rust. While Rust isn’t perfect, and plenty of criticisms aimed at the language are well-reasoned, the borrow checker is IMO the logical next step forward in “zero-cost abstraction” which is one of the strongest core philosophies behind C and C++.
The R4L effort seems to be structured sensibly, starting out with only allowing Rust code in (new) drivers. From what I can tell there’s comparatively little that has to be maintained upstream, but even that is encountering aggressive pushback.
I can’t help but feel like some devs have spent so much of their professional careers learning how to avoid the many footguns of C(++) that they fundamentally resent Rust for being a language which avoids most these problems, allowing fast code to be written with fewer bugs in less time and with less effort. This feeling is based on having written lots of C++ code for over 20 years, and having personally encountered devs who deeply resent Rust just because it’s not C.
Do you really believe the US Senate cares about 75 Nobel Laureates?
Yeah, as low as $61 on Amazon for 1TB. Pretty amazing if you’re old like me and remember diskettes.

I doubt doing it in software like that outperforms sqrtss/sqrtsd. Modern CPUs can do the conversions and the floating point sqrt in approximately 20-30 cycles total. That’s comparable to one integer division. But I wouldn’t mind being proven wrong.
Well, yeah, but you asked why they didn’t use integer sqrt. It’s something many programming languages just don’t have. Or if they do, it’s internally implemented as a sqrt(f64) anyway, like C++ does.
Most CPUs AFAIK don’t have integer sqrt instructions so you either do it manually in some kind of loop, or you use floating point…
The builtin u64.isqrt
seems to be available in nightly only, and additionally I guess the author didn’t want to use any external crates as part of their self-imposed challenge. Though I think there may be an off-by-one result with f64.sqrt
I don’t think this functionally breaks their u64 code because they loop to root_n + 1
.

There isn’t even any memory management in their code. And arguably the most interesting part of the article is implementing a bignum type from scratch.
The author pointed out they also could’ve just called openssl prime -generate -bits 1024
if they weren’t trying to learn anything. Rebuilding something from scratch and sharing the experience is valuable.
It’s not like Rust is the first language which requires you to reason about ownership. People still write tons and tons of C++. Rust is much faster to write than C++ in my experience, because ownership is checked by the compiler instead of requiring the human programmer to constantly think and reason about.
I wouldn’t write gameplay code in Rust like I posted above, but most of the complaints about the borrow checker making Rust somehow exceptionally hard to write are overblown imo. There’s a learning curve but then it makes sense.
Yeah, that’s a more nuanced take than mine. I sadly doubt this country will actually do anything to improve pay equality however, which I would agree lies at the root of the unpopularity of those jobs.
