Ah okay, didn't know that. Good luck wherever you are!

FWIW, as a high performance C++ dev who likes Rust but considers unsafe the biggest issue by far, it's encouraging to see important folk within the project believe there are issues…

It's honestly unfortunate that rust has been sold so hard on memory safety, so that when C++ folk don't spend tons of time in memory issues they think rust is pointless. I don't wa…

Duplicating meaning that the smart pointer deleter is going to need a copy of the allocator (or a pointer to it if you prefer, but allocators are already typically pointers). If yo…

I think there's a bit of confusion here around "value semantics". No C++ smart pointer has "value semantics", relative to its target T. You can see this because == performs address…

It's a pretty drastic assertion (and quite HN worthy) that a whole industry is abusing their developers, based on not even one job, but your impression of a job based on an intervi…

I would encourage you to benchmark linear search and binary search on a dynamic array (std::vector) of a million elements. You may be in for a surprise. I can only assume you have …

IIRC, Java interfaces are subtype polymorphism. Ad hoc polymorphism would be, for example, overloading.

I would assume that within unsafe you could simply do the same kinds of shenanigans you would do in C++, e.g. you have a fixed size struct that is just the "header", it's only crea…

It's hard to say. I think a lot of the Rust community actually hails from more of the web world, where security is rightfully a big concern, and the that's where actix was position…

Very curious where you work, because there's only really a handful of major places doing HFT (as opposed to algorithmic trading) and haven't heard of Rust being used at any of them…

I think this picture of how HFT and games work doesn't have much connection to how it actually does. In these industries you can't just get all or even most of the high performance…

Yes, he may well improve some algorithm, or rewrite some commonly used tool to improve efficiency. And researchers are often not incentivized to do that, so it would be great. But …

I normally don't bother but this comment is so profoundly ridiculous I had to say something. Tenured ML professors at the top 100 or so universities in the world aren't "most of us…

Except that in HFT we don't generally disable RTTI or exceptions. I work at a top HFT firm, have friends/colleagues at other top firms, have seen multiple people like Carl Cook at …

Well you can certainly elect to torture yourself if you really want to. Atomics in C++ compile to assembly in very straightforward ways and there isn't really an enormous design sp…

Dude I mean the context in which I'm discussing this is a large organization operating on timescales shorter than microseconds with numerous people involved in optimizing every sin…

I didn't intend to imply otherwise but I see my wording was unclear. I meant that D generally would be a hit, though it's only really speculation either way.

HFT doesn't subset C++ nor does it ignore the standard library. Given you're totally wrong about one I'm not inclined to believe you on the other, and I have an examples from the s…

I'm sure these people exist but they're the exception rather than the rule. The two biggest industries in SG14, the C++ low latency study group, are games and HFT. In both these ar…

That's a pretty vague statement though. vector and unique_ptr are class templates (generic classes). To understand them you need at least a basic idea of how that works, which you …

I think the author blows his credibility very early with this comment: > As I said, it’s a superficial example, but I think it shows a general difference in philosophy between C++ …

I'm not saying that D is defined by that. I'm simply saying that if you're comparing to C or C++, you are talking about use cases that are defined by performance and/or memory mana…

The whole "subset" argument is pretty thin. There are style/convention guides, and there are are more obscure features in C++ the same way there are more obscure features in other …

If you can tolerate GC then like 20 languages (as or less obscure than D) enter the conversation. If you can tolerate GC and the performance implications that go with it, then usin…
