It’s a fairly well-known trick in systems programming. Definitely not invented with zig, but perhaps popularized further. If you write enough systems code in C or Rust, you end up inventing it eventually. If you ever design a datastructure

Is there an original recording of him saying this. Feels like a huge stretch, discounting all technology invented after 1969! Does he address that? I often prefer the source material because so much context is lost in reporting.

Because block-argument is actually the “right way”. The phi-node is very un-natural.. in the same sort of way that pi should have been tau. Also, notice the connection here between Phi nodes and Continuation Passing Style (CPS). It because

That would be my guess. Or you can even consider that him focusing on happiness led to success.

Same. But I guess I’ve just accepted it and moved on. I’m willing to give that up for not having to give up 75% of my wake hours to a purely economic entity. I think I’m mostly surprised that so many smart/capable/successful peopl

Agreed. I don’t use social media of any kind. Not even on the desktop. I always run with Downtime on. All new apps are disallowed from running or notifying unless I whitelist them explicitly. You really don’t need this “attention porn” in y

Compile time. There are preprocessor #if guards all over the code base to provide different implementations for core operations. Many of these are used to provide a thread-safe version (e.g. atomic refcount). Presumably, these should work f

Am I the only one who thinks this is perfectly fine? The requirements for derive Clone are clearly defined. As with much in Rust, the type signature drives things, rather than the function body (contrast with C++ generics). Occasionally, th

You’re right. I think it ends up working out to a 4096 page on x86 machines, that’s probably what I remembered. Yes, _FORTIFY_SOURCE is a fabulous idea. I was just a bit shocked it wasn’t checked without _FORTIFY_SOURCE. If you’re doing FD_

The real fun thing is when the same application is using “select()” and then somewhere else you open like 5000 files. Then you start getting weird crashes and eventually trace it down to the select bitset having a hardcoded max of 4096 entr

The scrolling effect is very disorienting for me. I want the read the article, but it’s disrupting my focus significantly. Is there a version without all to fancy effects?

This is something I believe in. How can one get more involved in this? (Beyond donating)

I think I did something similar. I decided to severely control my information diet after November and switch to only RSS feeds that I have selected manually and HN. It’s gone better than I expected and I feel very little urge to go back. At

Yes, but it’s the old skool version of social media and the conversations here are generally higher quality and more genuine. I strongly disagree that it’s “on par with /.,xchan” HN also doesn’t seem to be as susceptible to rage-baitin

Between Kagi for ordinary web search and Claude for “complicated questions I don’t know how to phrase for a search engine”, I’m pretty happy right now. Great job to both organizations!

I’m glad someone is having fun in C++. Personally, after >20 years, I have to be done with C++. It’s just a mess. If I really need the low-level control, I can wrangle C (warts and all), otherwise Rust, Python, etc just make me happier.

I’ve never liked to conflation with fractions. Abuse of notation. And it causes so much confusion. Also integrals with “integrate f(x) dx” where people treat “dx” as some number than can be manipulated, when it’s more just part of the notat

You can fork and fix that with sed. Haha. I decided on using sigils and then my thought-process drifted to Perl/Php, so $ naturally felt like a variable definition (which naturally must pop from the stack). I guess ^ is “push ‘up’ to s

Thanks for the kind words. But if you’re looking for fancy data-structures, you won’t find them. Haha. It’s just a single object type (sum-type/tagged-union) and lots of cons cells. In other words, just a minimalist Lisp.

I thought of that. But then you’re making the semantics complicated. Say you really did want a (a) closure. Now you can’t have one, and you have to resort to more tricky wrapping. Not worth it.

Ha. Well I meant “add those operations to the C interpreter”, which would be like 4 lines of code.
